Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, specifically to a winch used in the production of power transmission towers. Background Technology

[0002] In the field of material handling, lifting equipment plays a crucial role, applied in various sectors such as industrial manufacturing, construction, and shipbuilding. The structural design of these devices directly impacts operational efficiency and safety. However, traditional lifting equipment often suffers from drawbacks such as complex structures and inconvenient operation. Currently available lifting equipment still has room for improvement in its connection structure and operation methods. For example, the connection between the hook and the rope may not be flexible enough, making it difficult to adapt to complex and changing working environments and lifting requirements. Furthermore, when multiple lifting devices need to work together, there is often a lack of an effective docking and transfer mechanism, which not only increases the difficulty of operation but also raises safety risks.

[0003] Chinese patent document CN103010938B discloses an automatic hook, the main structure of which includes: a specially designed through hole at the upper part of the hook head for easy installation and fixing. Inside the through hole, a pin is installed, with its two ends fixed to through holes in the side plates of the housing, ensuring structural stability. A spur gear is installed at the upper end of the hook head, which precisely meshes with the output gear of the reduction gear set, ensuring smooth transmission. The input gear of the reduction gear set meshes tightly with the gear on the output shaft of the motor, forming a highly efficient transmission system. The entire motor and reduction gear set are securely fixed to the side plates of the housing through a series of connectors, ensuring the stability of the equipment during operation. The motor is connected to a battery box and a control circuit board via wires. The battery box provides power to the motor, while the control circuit board controls the motor's start, stop, and operating speed. The control circuit board is also connected to an electromagnet, which, under the control of the circuit board, can engage or disengage to achieve specific mechanical actions. The battery box not only provides power to the electromagnet but also connects to a remote control receiver. The receiver receives external remote control signals and transmits them to the control circuit board for remote control. A rotating lifting lug is designed on the top plate of the housing, allowing the entire device to be hoisted and moved.

[0004] When processing workpieces, it is usually necessary to transfer them to the next work area. In the factory, there are often multiple winches that can transfer workpieces to perform multiple processes. However, when it is necessary to transfer the workpiece to the next hook, the workpiece cannot be placed on the ground because the coating on the workpiece is not dry. Therefore, it is common to use another hoisting device to hold the workpiece at another hoisting point, and then the hook on the previous hoisting device releases the workpiece. However, this requires multiple hoisting points, so the requirements for the shape of the workpiece and the setting of the hoisting points are relatively high. In summary, the existing workpiece transfer between two or more hoisting devices is inconvenient and affects efficiency. Summary of the Invention

[0005] This invention provides a winch for the production of power transmission towers, aiming to solve the problem of inconvenience in transferring workpieces between two or more winches in related technologies.

[0006] A winch for power transmission tower production includes a lifting rope and a hook connected to the bottom end of the rope. A connecting assembly for connecting the hook and the lifting rope is installed between the two. The connecting assembly includes:

[0007] The connector has a hook attached to its bottom. The top of the connector has two slide rails, one end of which extends to the front end of the connector. The front end has a magnetic assembly for engaging with the front end of other connectors.

[0008] The sliding part is slidably installed in one of the slide rails and connected to the suspension rope;

[0009] The limiting assembly includes two limiting blocks that are slidably mounted on the connecting seat and can enter the slide rail, and a triggering assembly for controlling the movement of the limiting blocks. The triggering assembly includes a triggering part one and a triggering part two. The triggering part one is located on the front end face of the connecting seat. When the front ends of the connecting seats on the two winches are brought together, the triggering part one abuts and triggers, causing the limiting blocks to slide out of the slide rail, thereby allowing the two sliding parts to slide from one connecting seat to the other connecting seat. During this process, the limiting blocks trigger the triggering part two, causing the limiting blocks to enter the slide rail on the other connecting seat and limit the movement of the sliding parts.

[0010] Its effects are as follows: During the workpiece handling process, the limiting block restricts the freedom of the sliding part. By preventing the sliding part from disengaging from the slide rail, the limiting block effectively prevents the sliding part from unexpectedly disengaging. When two connecting seats need to dock with each other, the triggering mechanism is activated, controlling the two limiting blocks to slide out of their respective slide rails. In this way, the sliding part on one connecting seat can smoothly slide into the slide rail of the other connecting seat, and at the same time, the sliding part on the other connecting seat will also slide into the slide rail of the first connecting seat. In this way, the interchangeability between connecting seats is realized, so that the workpiece can flow smoothly between the two winches. This method avoids the cumbersome process of removing the workpiece from one winch and then hanging it on another winch, greatly speeding up the docking and transfer speed between winches. In addition, it effectively protects the coating of the workpiece from damage, simplifies the operation process, significantly improves work efficiency, and ensures the continuity and smoothness of the entire process.

[0011] Preferably, the bottom of the connecting seat is connected to the hook by a chain link. The chain link design enhances the flexibility of the hook and the connecting seat, adapts to different lifting needs, and allows the hook to remain stable while also having a certain degree of movement during lifting. The chain link connection also facilitates the replacement or repair of the hook when needed, improving the ease of maintenance of the winch.

[0012] Preferably, the connecting seat is provided with a guide rod arranged in the left and right direction, and the limiting block is provided with a guide hole that cooperates with the guide rod. The cooperation between the guide rod and the guide hole ensures that the limiting block moves accurately within the slide rail, avoiding offset and jamming, and further improving the stability and reliability of the connecting seat. The surface of the guide rod is coated with wear-resistant material to extend its service life, reduce frictional resistance, and ensure smooth sliding of the limiting block.

[0013] Preferably, the triggering component further includes two symmetrically arranged racks slidably installed in the connecting seat and parallel to the guide rod. The ends of the two racks slidably connected to each other are respectively connected to two limiting blocks. Gears meshing with racks slidably are installed in the connecting seat. Racks 2 and 3 are respectively meshed on the two gears. Racks 2 and 3 are slidably installed in the connecting seat and perpendicular to the front end face of the connecting seat. The parts of racks 2 and 3 protruding from the front end face are the triggering parts. As the two connecting seats approach each other, racks 2 and 3 come into contact with each other and generate a mutual pushing action, causing racks 2 and 3 to drive the two gears to rotate. As the gears rotate, racks 1 are pushed and begin to move. During the movement, the elastic element deforms and accumulates elastic potential energy. At the same time, the limiting blocks begin to be gradually pushed out of the slide rail. When the two connecting seats are fully connected, that is, when the predetermined position is reached, the limiting blocks will no longer restrict the movement of the sliding component, and the sliding component can move freely on the slide rail.

[0014] Preferably, an elastic element is installed between the gear and the connecting seat to allow the limiting block to slide out of the slide rail. The elastic element gradually accumulates elastic potential energy during the rotation of the gear, and then releases it to pull the limiting block to slide quickly into the slide rail, ensuring that the sliding part is restricted within the slide rail.

[0015] Preferably, the outer end of rack two is provided with a receiving hole, the length of which is not less than the maximum length of rack two protruding from the connecting seat. The outer end of rack three is adapted to the receiving hole. The front end of rack two is provided with a limiting member to prevent rack three from entering the receiving hole. The limiting member ensures the timing of rack three entering the receiving hole during operation, thereby controlling the timing of the limit block sliding out of the slide rail, and thus realizing the degree of freedom control of the sliding part, thereby improving the reliability of the entire system.

[0016] Preferably, the limiting component includes a baffle and a resetting component. The baffle slides up and down at the front end of the rack two to prevent the rack three from entering the receiving hole. The resetting component is installed between the baffle and the rack two. The baffle has a through hole that matches the outer end of the rack three. The through hole allows the rack three to enter the receiving hole at the appropriate time. Initially, the through hole and the receiving hole are misaligned, thus preventing the rack three from entering the receiving hole. The top of the baffle extends into the slide rail, and the top of the baffle is designed to be wedge-shaped. When the sliding part slides along the slide rail, it pushes the baffle downward, causing the through hole to coincide with the receiving hole, thereby allowing the rack three to enter the receiving hole. This design ensures that the sliding part can perform degree-of-freedom conversion at the correct time and position.

[0017] Preferably, when rack three abuts against the front side of the baffle, there is a gap between the limiting block and the sliding part on the front projection plane. In the initial state, the through hole and the receiving hole are misaligned, the top of the baffle extends into the slide rail, and the top of the baffle is wedge-shaped. When the sliding part slides along the slide rail, it pushes the baffle downward, causing the through hole and the receiving hole to coincide. After docking, rack two and rack three are completely retracted into the connecting seat, and rack three is in close contact with the baffle. At this time, there is a certain gap between the limiting block and the sliding part on the front projection plane. As the sliding part slides along the slide rail, the sliding part will contact the inclined surface, which will squeeze the baffle, causing the baffle to gradually press down on the reset member, thereby causing the baffle to move downward. As the baffle moves downward, the through hole and the receiving hole gradually coincide, and the elasticity... The component releases its stored elastic potential energy, allowing the gear to rotate. The rotation of the gear allows rack three to smoothly insert into the receiving hole a certain distance. As rack three and rack two move relative to each other, the gear rotates, driving rack one to move. This causes the limiting blocks on the two connecting seats to contact the sides of the sliding part, thus completing the initial release of the limiting blocks. During this process, the inner wall of the through hole of the baffle abuts against rack three. Therefore, after the sliding part passes the baffle, the baffle cannot return to its original position. Finally, the baffle continues its movement trajectory, offsetting from the limiting blocks, while the outer end of rack three is fully inserted into the receiving hole. In this way, the limiting blocks can enter the slide rail, preventing the sliding part from sliding back and ensuring a stable connection between the sliding part and the connecting seat.

[0018] Preferably, the magnetic suction assembly includes two magnets, which are disposed on the front end face of the connecting seat and arranged symmetrically on the left and right. The magnetic poles on the outer sides of the two magnets are different. The mutual attraction between the magnets on the two connecting seats ensures that the connecting seats fit tightly, thereby achieving a stable connection between the two winches. This avoids safety hazards caused by unstable connection during workpiece transfer. In addition, the design of the magnetic suction assembly simplifies the docking process, reduces the difficulty of operation, and further improves work efficiency.

[0019] Preferably, the front end face of the connector has a mating hole, and a mating rod that matches the mating hole is fixedly installed on the front end face of the connector. The two connectors are stably connected through the mating hole and the mating rod. After the mating rod is inserted into the mating hole, a firm locking structure is formed, ensuring that the two connectors can only move in their front-back direction, thus improving overall stability. The magnetic attraction component further enhances the connection effect, making the docking process smoother. The precise fit between the mating rod and the mating hole ensures seamless docking between the connectors.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0021] 1. During the workpiece conveying process, the function of the limiting block is to restrict the sliding parts from disengaging from the slide rail to prevent the sliding parts from accidentally disengaging. When the two connecting seats are docked, the baffles on rack two and rack three abut against each other, causing rack two and rack three to drive the gear to rotate, thereby pushing rack one to move, realizing the deformation of the elastic element and accumulating elastic potential energy. As the limiting block is gradually pushed out of the slide rail, the two connecting seats are docked, and the limiting block no longer restricts the movement of the sliding parts.

[0022] 2. In subsequent operations, the sliding component slides along the slide rail and comes into close contact with the inclined plane. Through this contact, the baffle gradually presses down on the reset component, causing the baffle to move downwards. As the baffle descends, the through hole and the receiving hole gradually align, and the elastic component releases its stored elastic potential energy. This energy release drives the gear to rotate, which in turn drives rack three to move forward. Rack three inserts into the receiving hole a certain distance. As rack three moves, rack two also begins to move. The limiting blocks on the two connecting seats come into contact with the sides of the sliding component, completing the initial release of the limiting blocks. During this process, the baffle and the gear... The third rack operates under shearing action, so when the sliding component passes the baffle, the baffle cannot return to its original position. Subsequently, the baffle continues to move, dislocating from the limiting block. The outer end of the third rack is fully inserted into the receiving hole, and the limiting block enters the slide rail, preventing the sliding component from sliding backward. This ensures a stable connection between the sliding component and the connecting seat. After these steps are completed, the sliding component on the other connecting seat moves according to the same process, thus realizing the exchange connection between the two sliding components and the two connecting seats. Finally, the connecting seat carrying the workpiece successfully completes the connection with another winch.

[0023] 3. Through the precise matching of gears and racks, the linkage mechanism of baffles and limit blocks ensures the restriction of the movement freedom of the sliding part, and the timely release of the elastic element provides the necessary power, ultimately achieving a stable docking of the connecting seat, ensuring the reliability and safety of the entire repositioning process. This ingenious design not only improves hoisting efficiency but also greatly enhances the convenience of operation. With this design, the transfer and circulation of workpieces are more efficient in multi-winch collaborative work. Attached Figure Description

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1 As shown, a winch for power tower production includes a winch (not shown), a hook 1 and a hoisting rope 2. A connecting component 3 is installed between the hook 1 and the hoisting rope 2. The connecting component 3 connects the hook and the hoisting rope 2 together, and the convenience of workpiece transfer is further optimized by the connecting component 3.

[0037] like Figures 1-9 As shown, the connecting component 3 includes a connecting seat 31, a sliding part 32, and a limiting component 33. The bottom of the connecting seat 31 is connected to the hook 1 by a chain link, and the top of the sliding part 32 is connected to the lifting rope 2. The sliding part 32 is slidably installed on the connecting seat 31. The sliding part 32 is restricted by the limiting component 33 to ensure safety and stability during the hoisting process.

[0038] The top of the connecting seat 31 has two parallel slide rails 311, the front end of which passes through the front end face of the connecting seat 31. The sliding part 32 is slidably engaged in the slide rail 311, so the workpiece can be transferred by the movement of the sliding part 32. The design of the slide rail 311 makes the transfer process simple and direct, while also ensuring the stability of the transfer. The connecting seat 31 is provided with a guide rod 312 in the left-right direction near the front end face. The limiting component 33 is installed on the guide rod 312, so that it can slide along the guide rod 312. The sliding part 32 is used to restrict the sliding part 32 within the slide rail 311 or to allow the sliding part 32 to slide out of the slide rail 311. The front end face of the connecting seat 31 is provided with a magnetic attraction component for engaging with the front end face of other connecting seats 31. Through the attraction of the magnetic attraction component, it can be ensured that the two winches are connected quickly and accurately when docking. The front end face of the connecting seat 31 is provided with a docking hole, and a docking rod that matches the docking hole is fixedly installed on the front end face of the connecting seat 31. The two connecting seats 31 are guided by the docking hole and the docking rod, thereby achieving stable docking.

[0039] The magnetic attraction assembly consists of two magnets 313, which are designed in a symmetrical layout (e.g., ...). Figure 6 As shown, their magnetic poles are different. This unique design ensures that the two magnetic components can be precisely connected when they are docked. It is this precise docking mechanism that allows the two docking seats to fit together perfectly, thereby ensuring the stability and reliability of the entire system.

[0040] The limiting component 33 includes two limiting blocks 331 and a trigger component. The two limiting blocks 331 are symmetrically arranged, and each limiting block 331 has a guide hole that mates with a guide rod 312, thereby allowing the two limiting blocks 331 to slide in contact with the guide rod 312. The surface of the guide rod 312 is coated with a wear-resistant material to extend its service life, reduce frictional resistance, and ensure smooth sliding of the limiting blocks 331. The trigger component controls the sliding of the limiting blocks 331 along the guide rod 312, allowing the limiting blocks 331 to slide into and out of the slide rail 311. When transporting a workpiece, the limiting blocks 331 prevent the sliding part 32 from disengaging from the slide rail 311 (e.g., ...). Figure 6 As shown in the diagram, this prevents the sliding part 32 from accidentally disengaging. When the two connecting seats 31 are aligned, the triggering component controls the two limiting blocks 331 to slide out of the slide rail 311, thereby causing the sliding part 32 on the connecting seat 31 to slide into the slide rail 311 of the other connecting seat 31, and vice versa. This completes the interchange and facilitates the transfer of the workpiece between the two winches, avoiding the need to remove the workpiece from one winch and then hang it on another, ensuring efficient transfer and reducing potential damage. This design significantly improves the efficiency and safety of hoisting operations.

[0041] The triggering assembly includes two racks 332, two elastic elements 333, two gears 334, a second rack 335, a third rack 336, and a limiting element. The two racks are fixedly connected to two limiting blocks 331 respectively. The two elastic elements 333 (preferably torsion springs) are respectively mounted on the two gears 334, and both elastic elements 333 are connected to the connecting seat 31 to provide a restoring force. The first rack 332 is parallel to the guide rod 312. The second rack 335 and the third rack 336 are slidably mounted within the connecting seat 31 and are parallel to each other. The front ends of the second rack 335 and the third rack 336 protrude from the front face of the connecting seat 31, and the second rack 335 and the third rack 336 are at the same height. The rack 332 and rack 335 are offset from each other in height, and rack 335 and rack 332 are perpendicular to each other in the horizontal projection plane. Both rack 332 and rack 335 are engaged with gear 334. Another rack 332 and rack 336 are engaged with another gear 334. When the two connecting seats 31 approach each other, rack 335 and rack 336 abut against each other, thereby causing rack 335 and rack 336 to drive gear 334 to rotate, which in turn drives rack 332 to move, causing elastic element 333 to deform and accumulate elastic potential energy. At the same time, the limiting block 331 is gradually pushed out of slide rail 311. When the two connecting seats 31 are docked, the limiting block 331 no longer restricts the movement of sliding part 32.

[0042] The outer end of rack 2 335 is provided with a receiving hole. The length of the receiving hole is not less than the maximum length of rack 2 335 protruding from the connecting seat 31, and the length of the docking rod is greater than twice the maximum length of rack 2 335 protruding from the connecting seat 31. This ensures that when the two docking seats are docked, the docking rod is inserted into the docking hole first, avoiding deviation between rack 2 335 and rack 336. The outer end of rack 3 336 is smaller and fits the receiving hole. The limiting member is installed on the outside of the receiving hole, thereby limiting the insertion of rack 3 336 into the receiving hole.

[0043] In the initial state, the limiting member ensures that rack 336 will not accidentally enter the receiving hole, thereby preventing the movement of the limit block 331 when not needed. When the two winches are ready to dock, as the connecting seat 31 gradually approaches, the front end of rack 2 335 will first contact the limiting member. This contact will push rack 336 to move along its installation direction until it is completely retracted into the connecting seat 31. After that, the sliding part 32 slides along the slide rail 311, the limiting member is overcome, and the outer end of rack 336 can enter the receiving hole. This action no longer restricts the rotation of gear 334. The elastic member 333 releases elastic potential energy, thereby causing rack 1 332 to move, while pushing the limit block 331 to slide along the guide rod 312 and gradually enter the slide rail 311. The movement of rack 1 332 will drive gear 334 to rotate, so that the outer end of rack 336 enters the receiving hole, thereby allowing rack 336 and rack 2 335 to be inserted into each other.

[0044] The limiting components include a baffle 337 and a reset component 338. The baffle 337 is mounted on the front end of the rack 2 335 by sliding up and down, effectively preventing the rack 3 336 from entering the receiving hole. The baffle 337 has a through hole that matches the outer end of the rack 3 336. The reset component 338 (preferably a spring) is installed between the baffle 337 and the rack 2 335. In the initial state, the through hole is offset from the receiving hole. The top of the baffle 337 extends into the slide rail 311, and the top of the baffle 337 is wedge-shaped, that is, both the front and rear sides of the top of the baffle 337 are inclined surfaces.

[0045] When racks 2 (335) and 3 (336) are fully retracted into the connecting seat 31, and rack 3 (336) abuts against baffle 337, there is a gap between the limiting block 331 and the sliding part 32 on the front projection plane. When the sliding part 32 slides along the slide rail 311, it abuts against the inclined surface, causing baffle 337 to gradually press down on the reset member 338, causing baffle 337 to move downwards, aligning the through hole with the receiving hole. The elastic member 333 releases its elastic potential energy, causing gear 334 to rotate, thus allowing rack 3 (336) to smoothly insert into the receiving hole a certain distance. Rack 3 (336) and rack 2 (335) move, causing the limiting blocks 331 on the two connecting seats 31 to abut against the sides of the sliding part 32. After the initial release of the limiting block 331 is completed, the baffle 337 and the rack 336 are sheared together. Therefore, when the sliding part 32 passes the baffle 337, the baffle 337 cannot be reset. Finally, the baffle 337 continues to move and is offset from the limiting block 331. The outer end of the rack 336 is fully inserted into the receiving hole, so that the limiting block 331 enters the slide rail 311, preventing the sliding part 32 from sliding back and ensuring the stable docking of the sliding part 32 and the connecting seat 31. After that, the sliding part 32 on the other connecting seat 31 moves according to the above process, thereby completing the exchange connection between the two sliding parts 32 and the two connecting seats 31, so that the connecting seat 31, carrying the workpiece, completes the connection with another winch.

[0046] The work steps are as follows:

[0047] S1. In the production line, the first winch is responsible for driving the workpiece along a predetermined path until it reaches the position of the second winch.

[0048] S2. Adjust the height of the first winch so that the connecting component 3 is aligned with the connecting component 3 of the second winch;

[0049] S3. Move the connecting component 3 on the second winch so that the docking rod on the connecting seat 31 is inserted into the docking hole;

[0050] S4. Gradually bring the two connecting seats 31 closer together, causing racks 2 335 and 336 to abut against each other, thereby rotating gear 334. The rotation of gear 334 causes rack 1 332 to move, driving the limiting block 331 to slide out of slide rail 311, no longer restricting the sliding part 32 (state as follows). Figure 1 (as shown)

[0051] S5. Push the sliding part 32 on the winch to slide, so that the sliding part 32 abuts against the baffle 337. The baffle 337 moves down, and the through hole on the baffle 337 gradually overlaps with the receiving hole. The rack 336 smoothly inserts into the receiving hole a certain distance.

[0052] S6. Continue to push the sliding part 32 so that it passes completely through the limiting block 331. The elastic element 333 releases elastic potential energy to make the gear 334 rotate, so that the rack 336 is fully inserted into the receiving hole. The limiting block 331 enters the slide rail 311, preventing the sliding part 32 from sliding back.

[0053] S7. Control the second winch to pull the rope up a short distance, so that the second winch applies a certain lifting force to the workpiece;

[0054] S8. Slide the other sliding part 32 into the slide rail 311 of the connecting seat 31 without a workpiece, and repeat the above steps to ensure that the sliding parts 32 on both connecting seats 31 are stably connected to the limiting block 331 (as shown in the figure). Figure 5 (as shown)

[0055] S9. Confirm that the sliding parts 32 on the two connecting seats 31 are fully engaged with the limiting block 331 to ensure a stable connection.

[0056] S10 overcomes the magnetic force to separate the two connecting seats 31, thereby completing the transposition and transferring the workpiece to the second winch.

[0057] In the above process, by alternately applying tension through the first and second winches, the sliding part 32 can be easily pushed, avoiding the sliding part 32 from being inconvenient to slide due to excessive tension. At the same time, this design also avoids the possibility of jamming or damage to the sliding part 32 when subjected to excessive tension, further improving the service life and safety of the winches. In specific operation, the operator only needs to follow the above steps to easily complete the hoisting and transfer of the workpiece, greatly improving work efficiency and accuracy. In summary, the present invention successfully solves the problems existing in the traditional winch in the process of workpiece transfer and circulation, bringing a more convenient, efficient and safe solution to hoisting operations.

[0058] Working principle: When transporting the workpiece, the limiting block 331 restricts the sliding part 32 from disengaging from the slide rail 311, thereby preventing the sliding part 32 from accidentally disengaging. When the two connecting seats 31 are in contact, the baffle 337 on rack two 335 and rack three 336 abuts against each other, thereby causing rack two 335 and rack three 336 to drive gear 334 to rotate, which in turn drives rack one 332 to move, causing the elastic element 333 to deform and accumulate elastic potential energy. At the same time, the limiting block 331 is gradually pushed out of the slide rail 311, and the two connecting seats 31 are connected. At this time, the limiting block 331 no longer restricts the movement of the sliding part 32. In subsequent operations, the sliding part 32 slides along the slide rail 311. At this time, the sliding part 32 is in close contact with the inclined surface. Through this contact, the baffle 337 gradually presses down on the reset member 338, causing the baffle 337 to move downward. As the baffle 337 descends, the through hole and the receiving hole gradually align, and the elastic member 333 releases its stored elastic potential energy. This energy release causes the gear 334 to start rotating. The rotation of the gear 334... The rack 336 moves forward, inserting itself a short distance into the receiving hole. As rack 336 moves, rack 2 335 also begins to move. The limiting blocks 331 on the two connecting seats 31 contact the sides of the sliding part 32, completing the initial release of the limiting blocks 331. During this process, the baffle 337 and rack 336 undergo a shearing action. Therefore, after the sliding part 32 passes the baffle 337, the baffle 337 cannot return to its original position. Subsequently, the baffle 337 continues to move, interacting with... With the limit block 331 offset, the outer end of the rack 336 is fully inserted into the receiving hole, and the limit block 331 enters the slide rail 311, preventing the sliding part 32 from sliding back, thus ensuring a stable connection between the sliding part 32 and the connecting seat 31. After these steps are completed, the sliding part 32 on the other connecting seat 31 moves according to the same process, thereby realizing the exchange connection between the two sliding parts 32 and the two connecting seats 31. Finally, the connecting seat 31, carrying the workpiece, successfully completes the connection with another winch.
