Specification

Description:Field of the Invention


The present disclosure generally relates to mechanical lifting systems. Further, the present disclosure particularly relates to a system featuring a manual hoist with a gear assembly and tension handle.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
In various fields, manual hoisting systems are employed to lift and lower equipment. Manual hoists are generally employed in industries such as construction, manufacturing, and shipping for handling heavy loads. Conventional hoists typically involve manual operation with basic components to wind and unwind cables or ropes for lifting or lowering a load. Historically, hoisting systems have been associated with a wide range of designs and methods for operation, including pulley-based systems, drum-based systems, and others. Such systems provide a fundamental means of controlling load movements.
Further, drum-based manual hoists are known to utilize a rotational drum to wind and unwind cables. A rotational drum enables the winding of the cable as the load is lifted and unwinding during lowering. Such systems often suffer from inadequate speed control mechanisms, leading to erratic movement of the load. Speed control in conventional hoists typically relies on manual force, which results in limited precision. Moreover, without speed variation control, there is a significant risk of overload on the hoist, which may result in failure or hazardous situations during operation. Consequently, conventional manual hoists often lack the precision needed for various load-lifting applications.
Moreover, prior manual hoists generally incorporate limited features for controlling tension during operation. Tension management is crucial in preventing slack in the cable, which can lead to unwanted shifts in the load, reduced control, or sudden movements that can cause accidents or damage. Such limitations in conventional systems create challenges in ensuring smooth and controlled movements, particularly during the ascent or descent of equipment. A lack of tension control may also affect the overall longevity of the hoist system as well as contribute to wear and tear on the cables and other related components.
Additionally, conventional manual hoisting systems are often cumbersome to operate due to their lack of ergonomic features. The absence of a suitable mechanism to assist in manually controlling tension and descent speed places an undue physical strain on the operator, further complicating the usage of such systems in demanding conditions. As a result, operators may face difficulty in maintaining smooth and consistent control over the movement of heavy loads, thereby compromising safety and efficiency during operation.
Furthermore, although some manual hoists attempt to provide basic safety measures, such systems are associated with minimal load control, often requiring external mechanisms to achieve the desired level of precision and safety. These systems generally do not account for variable speed control or effective tension management, thus exposing operators and equipment to risk. The absence of an integrated system that addresses both speed and tension control introduces inefficiencies and safety hazards, making conventional systems less reliable for various industrial applications.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for load-lifting operations, specifically in relation to tension control and speed management within manual hoisting systems.

FIG. 1 illustrates a system (100), in accordance with the embodiments of the present disclosure. In an embodiment, a manual hoist (102) includes a rotational drum (104) that serves as a core component for winding and unwinding a cable or rope. Said manual hoist (102) is utilised to lift and lower heavy equipment or materials, often in environments such as construction sites, warehouses, or industrial facilities. The rotational drum (104) may be constructed from durable materials, such as steel or aluminium, to ensure the required mechanical strength for supporting the tension created during lifting operations. The rotational drum (104) is mounted to allow rotation around its axis, thereby enabling the cable or rope to be wound or unwound based on the direction of rotation. The cable or rope is wrapped around said rotational drum (104) as the drum rotates in one direction to lift equipment and unwound as the drum rotates in the opposite direction to lower said equipment. The size of the rotational drum (104) may vary depending on the specific load requirements of the system (100), allowing for flexibility in the hoisting applications. Additionally, the rotational drum (104) can be integrated with other components, such as braking systems, to control the winding and unwinding process, thereby providing operational safety during lifting and lowering activities.
In an embodiment, a gear assembly (106) is integrated with the rotational drum (104) to provide variable speed control in the system (100). Said gear assembly (106) includes a set of interlocking gears that regulate the speed at which the rotational drum (104) winds or unwinds the cable or rope. The gear assembly (106) may include different types of gears, such as spur gears, helical gears, or planetary gears, depending on the design requirements and desired speed variations. The integration of said gear assembly (106) with the rotational drum (104) allows the system (100) to operate at varying speeds based on the load being lifted or lowered. By adjusting the gearing ratio, said gear assembly (106) allows the operator to slow down or accelerate the winding and unwinding process, providing greater control over the movement of equipment. Said gear assembly (106) also helps in distributing the mechanical forces evenly across the system (100), which contributes to the durability of the hoist and prolongs the life of the equipment.
In an embodiment, a tension handle (108) engages with the gear assembly (106) to facilitate the operation of the manual hoist (102). Said tension handle (108) is manually operated by an individual to engage or disengage the gear assembly (106), allowing the user to control the ascent or descent of equipment within the system (100). The tension handle (108) is typically connected to a mechanical linkage that interfaces with the gears of the gear assembly (106), translating the manual input into controlled mechanical action. Said tension handle (108) may include ergonomic features, such as grips or handles, to enhance user comfort and ease of use during operation. By engaging said tension handle (108), the operator can control the amount of force exerted on the rotational drum (104), thereby regulating the speed of lifting or lowering operations. The tension handle (108) is positioned in a manner that allows for easy access by the user while operating the hoist system (100).
In an embodiment, the rotational drum (104) is configured with a grooved surface, wherein the grooves are designed to guide the cable uniformly during both winding and unwinding operations. Said grooves are oriented in a spiral or helical pattern around the surface of the rotational drum (104), which aids in aligning the cable properly as it wraps around the drum. This uniform guidance of the cable helps maintain consistent tension throughout the operation of the manual hoist (102), preventing tangling or uneven coiling. The grooves also serve to distribute the load evenly across the surface of the drum, reducing localized stress points that could potentially cause damage to the cable or the drum itself. Depending on the specific load and operational requirements, the grooves may vary in depth and spacing, ensuring compatibility with various types of cables or ropes. The configuration of the grooves allows the system (100) to handle various loads smoothly, providing reliability and safety during lifting and lowering operations.
In an embodiment, the gear assembly (106) is positioned in coaxial alignment with the rotational drum (104), meaning that both components share a common central axis. This alignment enables the gear assembly (106) to engage directly with the rotational drum (104) during lifting operations, providing a more efficient transfer of mechanical energy from the manual hoist (102) to the lifting mechanism. The coaxial positioning reduces the complexity of the system (100) by eliminating the need for additional linking mechanisms between the gear assembly (106) and the rotational drum (104), allowing for a more compact and streamlined design. This direct engagement improves the responsiveness of the manual hoist (102) during operation, enabling precise control over the speed and direction of the drum's rotation. The positioning also reduces mechanical wear on the system components, as the forces are transmitted directly along the common axis, minimizing friction and misalignment issues.
In an embodiment, the tension handle (108) intersects the gear assembly (106) at an oblique angle, which provides the operator with increased leverage during operation. This angled intersection is strategically designed to enhance the mechanical advantage of the manual hoist (102), allowing for greater control over the rotational speed of the rotational drum (104) during lifting and lowering operations. By positioning the tension handle (108) at an oblique angle, the operator is able to apply force more efficiently, making it easier to manage heavier loads with less manual effort. The intersection between the tension handle (108) and the gear assembly (106) also allows for smoother transitions between different speeds, ensuring that the system (100) operates with minimal jerking or sudden movements. The oblique angle at which the handle intersects the gear assembly (106) provides a balance between force and precision, giving the operator control over both speed and the amount of force applied during the lifting process.
In an embodiment, the gear assembly (106) incorporates a planetary gear set, which interfaces directly with the rotational drum (104) to distribute the load evenly across the system (100). The planetary gear set consists of multiple gears, including a central sun gear and several planet gears that rotate around the sun gear within an outer ring. This configuration allows for the even distribution of mechanical forces throughout the gear assembly (106), preventing localized stress points that could lead to premature wear or failure. By distributing the load evenly, the planetary gear set reduces the amount of torque required to operate the manual hoist (102), making the lifting and lowering process more efficient. The interaction between the planetary gear set and the rotational drum (104) ensures smooth and consistent operation, even under heavy loads, while maintaining the structural integrity of the hoist. The planetary gear set also allows for greater torque control, enabling the system (100) to lift heavier objects with less manual input.
In an embodiment, the rotational drum (104) comprises a ratchet unit that is located adjacent to the tension handle (108), said ratchet unit being configured to permit unidirectional movement of the rotational drum (104). The ratchet unit serves as a safety mechanism, preventing the accidental lowering of equipment during the lifting process by allowing the drum (104) to rotate in only one direction. The unidirectional movement restricts the rotational drum (104) from unwinding unless the operator manually disengages the ratchet unit, ensuring that the load remains securely in place while lifted. The ratchet unit may be constructed from durable materials, such as steel or reinforced plastic, to withstand the mechanical forces encountered during heavy lifting operations. The inclusion of the ratchet unit within the system (100) adds an additional layer of safety, making the manual hoist (102) suitable for applications where secure lifting is critical.
In an embodiment, the tension handle (108) is longitudinally connected to a tension spring, wherein said tension spring is positioned to absorb shock during the operation of the manual hoist (102). The tension spring serves to reduce the strain on the gear assembly (106) during rapid lifting or lowering movements by dampening sudden jerks or shifts in load. The placement of the tension spring ensures that mechanical forces generated during operation are evenly distributed across the system (100), preventing damage to the internal components. By absorbing shocks, the tension spring also contributes to smoother motion, allowing the operator to lift and lower loads without experiencing abrupt changes in speed or resistance. The tension spring may be made from materials such as tempered steel, which provides both elasticity and strength, ensuring long-term durability during repeated use.
In an embodiment, the system (100) further comprises a rail mounting bracket that is attached to the manual hoist (102). Said rail mounting bracket is arranged to interface with a railway carriage structure, providing secure attachment and facilitating the use of the system (100) in mobile installation environments. The rail mounting bracket allows the manual hoist (102) to be mounted on a variety of rail systems, such as those used in warehouses, factories, or outdoor environments where equipment needs to be moved along a track. The bracket may include adjustable clamps or fasteners that secure the manual hoist (102) to the rail, preventing slippage or movement during operation. The inclusion of the rail mounting bracket makes the system (100) versatile, allowing for easy transportation of heavy loads along pre-determined paths, while maintaining stability and control.
In an embodiment, the gear assembly (106) is enclosed within a casing, wherein said casing is configured with ventilation slots to allow airflow and cool the internal components of the system (100) during prolonged use. The casing serves to protect the gear assembly (106) from external elements such as dust, debris, and moisture, which could otherwise impair the performance of the hoist. The ventilation slots are strategically placed to promote the flow of air over the gears, preventing overheating that could lead to mechanical failure. The material of the casing may be chosen for its durability and heat resistance, ensuring that the gear assembly (106) remains protected even in harsh operating conditions. The design of the casing ensures that the system (100) can be used for extended periods without risk of overheating or damage to the internal components.
In an embodiment, the tension handle (108) comprises an ergonomic grip structure, wherein said grip is molded to fit comfortably in the operator's hand. The ergonomic design of the grip reduces hand fatigue and allows for extended use of the manual hoist (102) without discomfort. The grip may be made from materials such as rubber or plastic, which provide both durability and a non-slip surface for the operator. The shape of the ergonomic grip is designed to fit the contours of the hand, providing a secure and comfortable hold during the operation of the system (100). The inclusion of the ergonomic grip structure enhances the usability of the manual hoist (102), allowing the operator to exert manual force effectively while minimizing strain on the hand and wrist.
FIG. 2 illustrates sequential diagram of the system (100), in accordance with the embodiments of the present disclosure. The system (100) includes a manual hoist (102), which features a rotational drum (104) responsible for winding and unwinding operations. The rotational drum (104) interacts with a gear assembly (106), which provides variable speed control, allowing for precise adjustment during the winding and unwinding of cables or ropes. The gear assembly (106) facilitates controlled movement by engaging with the rotational drum (104) to manage the ascent and descent of equipment. A tension handle (108) engages with the gear assembly (106) at an oblique angle, enabling manual control over the hoisting process. This interaction between the tension handle (108) and the gear assembly (106) provides the operator with leverage for smooth and controlled movement of heavy loads, ensuring safe and efficient operation of the system. The system's components work together to allow manual control over lifting and lowering equipment, making it suitable for various industrial and construction applications requiring reliable load management.
In an embodiment, manual hoist (102) features rotational drum (104) configured to wind and unwind. Said rotational drum (104) enables controlled winding and unwinding of cables or ropes, allowing manual hoist (102) to lift or lower equipment effectively. The rotational drum (104) provides a mechanical advantage by transforming manual input into rotational movement, thereby controlling the ascent or descent of loads. This winding mechanism ensures that equipment can be moved with precision, making it suitable for applications requiring fine-tuned adjustments in load positioning. The manual operation of manual hoist (102) allows for versatility in various environments without relying on external power sources.
In an embodiment, rotational drum (104) is configured with a grooved surface, with said grooves oriented to guide a cable uniformly during winding and unwinding operations. The grooved surface aids in distributing tension evenly across the cable, reducing the risk of slippage or uneven winding. This consistent tension management enhances the stability of the hoisting process by ensuring that the cable remains securely aligned along the grooves during movement. Such configuration also minimizes wear on the cable and rotational drum (104), contributing to prolonged system durability and reducing the need for frequent maintenance.
In an embodiment, gear assembly (106) is positioned in coaxial alignment with rotational drum (104). The coaxial alignment allows both components to share a common rotational axis, facilitating smooth and efficient engagement between gear assembly (106) and rotational drum (104) during operation. This configuration reduces energy loss due to misalignment and enables consistent torque transfer from gear assembly (106) to rotational drum (104). The coaxial relationship also optimizes load handling during lifting, ensuring that mechanical forces are uniformly distributed along the shared axis.
In an embodiment, tension handle (108) intersects gear assembly (106) at an oblique angle. The oblique intersection provides additional leverage, allowing the operator to apply less force while achieving effective control over the rotational speed of rotational drum (104). This angled configuration improves manual control during lifting and lowering operations, enabling smoother transitions between different movement speeds. The leverage gained from the oblique angle enhances the operator's ability to manage heavy loads with greater precision, while also reducing strain on the gear assembly (106).
In an embodiment, gear assembly (106) incorporates a planetary gear set that interfaces with rotational drum (104). Said planetary gear set distributes the mechanical load evenly across multiple gears, reducing wear on individual components and enhancing the overall durability of gear assembly (106). The planetary gear configuration allows for high torque transmission within a compact design, enabling efficient operation even under heavy load conditions. By distributing the load evenly, the planetary gear set improves the longevity of both gear assembly (106) and rotational drum (104) during prolonged use.
In an embodiment, rotational drum (104) comprises a ratchet unit adjacent to tension handle (108). Said ratchet unit allows unidirectional movement of rotational drum (104), preventing accidental lowering of equipment while lifting operations are in progress. The unidirectional movement mechanism acts as a safety feature, ensuring that the load can only be lowered intentionally when the ratchet is disengaged.
