Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and in particular to a winch for producing power towers. Background Art

[0002] In the field of material handling, lifting devices play a vital role and are used in many fields such as industrial manufacturing, construction, and ship assembly. The structural design of these devices has a direct impact on operational efficiency and safety. However, traditional lifting devices often have defects such as complex structure and inconvenient operation. There is still room for improvement in the connection structure and operation method of the lifting devices currently on the market. For example, the connection method between the hook and the lifting rope may not be flexible enough, which makes it difficult for them to adapt to complex and changing working environments and lifting requirements. In addition, 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 increases safety risks.

[0003] Chinese patent application CN103010938B discloses an automatic lifting hook. Its main structure includes a specially designed through-hole on the upper portion of the hook head for easy installation and fixation. A pin is installed within the through-hole, with its ends secured to through-holes in the housing's two side panels, ensuring structural stability. A spur gear is mounted on the upper end of the hook head. This spur gear precisely meshes with the output gear of the reduction gear set, ensuring smooth transmission. The input gear of the reduction gear set tightly meshes with the gear on the motor's output shaft, forming an efficient transmission system. The entire motor and reduction gear set are securely fixed to the housing's vertical panels via a series of connectors, ensuring stability during operation. The motor is connected to a battery pack and a control circuit board via wires. The battery pack provides energy to the motor, while the control circuit board controls the motor's start, stop, and speed. The control circuit board is also connected to an electromagnet, which, under the control of the circuit board, can engage or release to achieve specific mechanical movements. The battery box not only provides power to the electromagnet but also connects to the remote control receiver, which 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 a workpiece, it is usually necessary to transfer the workpiece to the next work area. In the factory, there are often multiple winches that can transfer the workpiece, so as to carry out multiple processes. However, when the workpiece needs to be transferred to the next hook, the workpiece cannot be placed on the ground because the coating on the workpiece is not dry. Therefore, another lifting device is often used to lift the workpiece at another lifting point, and then the hook on the previous lifting device releases the workpiece. However, this requires multiple lifting points. Therefore, the shape of the workpiece and the setting of the lifting points are relatively high. In summary, it is inconvenient to transfer workpieces between two or more existing lifting devices, which affects efficiency. Summary of the Invention

[0005] The present invention provides a winch for producing electric power towers, aiming to solve the problem of inconvenience in transferring workpieces between two or more winches in the related art.

[0006] A winch for producing an electric power tower comprises a lifting rope and a hook connected to the bottom end of the lifting rope, wherein a connecting assembly for connecting the hook and the lifting rope is installed between the hook and the lifting rope, and the connecting assembly comprises: Connecting seat, the hook is connected to the bottom of the connecting seat, and two slide rails are provided on the top of the connecting seat, and one end of the two slide rails extends to the front end surface of the connecting seat, and a magnetic attraction component is provided on the front end surface for connecting with the front end surface of other connecting seats; A sliding portion, slidably mounted in one of the slide rails and connected to the suspension rope; The limit assembly includes two limit blocks that are slidably installed on the connecting seat left and right and can enter the slide rail, and a trigger assembly for controlling the movement of the limit blocks. The trigger assembly includes trigger part one and trigger part two. Trigger part one is located on the front end surface of the connecting seat. When the front ends of the connecting seats on the two winches are butted together, trigger part one is triggered to cause the limit block to slide out of the slide rail, thereby causing the two sliding parts to slide from one of the connecting seats to the other connecting seat. During this process, the limit block triggers trigger part two, causing the limit block to enter the slide rail on the other connecting seat and limit the sliding part.

[0007] The effect is that: during the workpiece transportation process, the limit block plays a role in limiting the freedom of the sliding part. The limit block effectively prevents the sliding part from escaping from the slide rail by limiting the sliding part. When the two connecting seats need to dock with each other, the trigger mechanism will be activated to control the two limit blocks to slide out from 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. At the same time, the sliding part on the other connecting seat will also slide into the slide rail of the first connecting seat accordingly. In this way, the interchange between the connecting seats is realized, so that the workpiece can flow smoothly between the two winches. This method avoids the tedious process of removing the workpiece from one winch and then mounting it on another winch, greatly speeding up the docking and transfer speed between the winches. In addition, it also 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.

[0008] Preferably, the bottom of the connecting seat is connected to the hook by a chain ring. The chain ring design enhances the flexibility of the hook and the connecting seat, adapts to different lifting requirements, and enables the hook to remain stable during the lifting process while also having a certain degree of mobility. The chain ring connection method also facilitates the replacement or maintenance of the hook when necessary, thereby improving the maintenance convenience of the winch.

[0009] Preferably, the connecting seat is provided with a guide rod arranged along the left and right directions, and the limit 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 limit block moves accurately in 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 the service life, reduce friction resistance, and ensure smooth sliding of the limit block.

[0010] Preferably, the trigger assembly also includes two symmetrically arranged racks 1 that are slidably mounted in the connecting seat and parallel to the guide rod, and one end of the two racks 1 that are close to each other is connected to the two limit blocks respectively. A gear meshing with the rack 1 is rotatably mounted in the connecting seat, and a rack 2 and a rack 3 are respectively meshed and connected on the two gears. The rack 2 and the rack 3 are both slidably mounted in the connecting seat and are perpendicular to the front end surface of the connecting seat. The parts of the rack 2 and the rack 3 that protrude from the front end surface are the trigger part 1. In the process of the two connecting seats approaching each other, the rack 2 and the rack 3 contact each other and produce a mutual pushing effect, causing the rack 2 and the rack 3 to drive the two gears to rotate respectively. As the gears rotate, the rack 1 is pushed and starts to move. During the movement, the elastic member deforms and accumulates elastic potential energy. At the same time, the limit block begins to be gradually pushed out from the slide rail. When the two connecting seats are fully docked, that is, reaching the predetermined position, the limit block will no longer impose restrictions on the movement of the sliding component, and the sliding component can move freely on the slide rail.

[0011] Preferably, an elastic member is installed between the gear and the connecting seat to make the limit block slide out of the slide rail. The elastic member gradually accumulates elastic potential energy during the rotation of the gear and then releases it, pulling the limit block to slide quickly into the slide rail, ensuring that the sliding part is confined within the slide rail.

[0012] Preferably, a receiving hole is provided at the outer end of rack two, and the length of the receiving hole is not less than the maximum length of the protruding connecting seat of rack two. The outer end of rack three is adapted to the receiving hole, and a limiting member is provided at the front end of rack two for preventing 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, thereby realizing control of the degree of freedom of the sliding part, thereby improving the reliability of the entire system.

[0013] Preferably, the limiting member includes a baffle and a reset member. The baffle slides up and down at the front end of rack two to prevent rack three from entering the receiving hole. The reset member is installed between the baffle and rack two. The baffle is provided with a through hole that matches the outer end of rack three. The through hole is used to allow rack three to enter the receiving hole at an appropriate time. In the initial state, the through hole and the receiving hole are staggered, thereby preventing rack three from entering the receiving hole. The top of the baffle extends into the slide rail and 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 rack three to enter the receiving hole. This design ensures that the sliding part performs the degree of freedom conversion at the correct time and position.

[0014] Preferably, when rack three abuts against the front side of the baffle, there is a gap between the limit block and the sliding part on the front projection surface. In the initial state, the through hole and the accommodating hole are staggered, 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 to move downward so that the through hole and the accommodating hole coincide with each other. After the docking is completed, 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 limit block and the sliding part on the front projection surface. 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 the reset part downward, thereby causing the baffle to move downward. As the baffle moves downward, the through hole and the accommodating hole gradually coincide with each other, and the elastic The gear releases its stored elastic potential energy, allowing the gear to rotate. The rotating action of the gear enables rack three to be smoothly inserted into the accommodating hole for a distance. As rack three and rack two move relative to each other, the gear rotates, and the gear drives rack one to move, so that the limit blocks on the two connecting seats contact the side surfaces of the sliding part, thereby completing the initial release of the limit block. In this process, the inner wall of the through hole of the baffle and rack three are in contact with each other. Therefore, when the sliding part passes over the baffle, the baffle cannot return to its original position. Finally, the baffle continues its movement trajectory and is staggered with the limit block, while the outer end of rack three is completely inserted into the accommodating hole, so that the limit block can enter the slide rail, preventing the sliding part from sliding back, thereby ensuring stable docking between the sliding part and the connecting seat.

[0015] Preferably, the magnetic attraction component includes two magnets, which are arranged on the front end surface of the connecting seat and are symmetrically arranged on the left and right. The outer poles of the two magnets are different. The mutual attraction of the magnets on the two connecting seats ensures that the connecting seats fit tightly, thereby achieving a stable connection between the two winches and avoiding safety hazards caused by unstable connection during the flow of workpieces. In addition, the design of the magnetic attraction component simplifies the docking process, reduces the difficulty of operation, and further improves work efficiency.

[0016] Preferably, a docking hole is provided on the front end surface of the connecting seat, and a docking rod adapted to the docking hole is fixedly installed on the front end surface of the connecting seat. The two connecting seats are stably docked through the docking hole and the docking rod. After the docking rod is inserted into the docking hole, a firm locking structure is formed to ensure that the two connecting seats can only move along their front and rear directions, thereby improving the overall stability. The magnetic suction component further enhances the connection effect, making the docking process smoother. The precise matching of the docking rod and the docking hole ensures seamless docking between the connecting seats.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are: 1. During the workpiece conveying process, the function of the limit block is to limit the sliding component from escaping from the slide rail to prevent the sliding component from accidentally detaching. When the two connecting seats are docked with each other, the baffles on rack 2 and rack 3 conflict with each other, prompting rack 2 and rack 3 to drive the gear to rotate, thereby pushing rack 1 to move, realizing the deformation of the elastic member and accumulating elastic potential energy. As the limit block is gradually pushed out of the slide rail, the two connecting seats are docked, and the limit block no longer restricts the movement of the sliding component; 2. In the subsequent operation, the sliding component slides along the slide rail and comes into close contact with the inclined surface. Through this contact, the baffle gradually presses the reset component downward, causing the baffle to move downward. As the baffle descends, the through hole and the receiving hole gradually align, and the elastic component releases its stored elastic potential energy. The release of this energy drives the gear to rotate, which in turn drives the rack three to move forward. The rack three is inserted into the receiving hole for a certain distance. As the rack three moves, the rack two also starts to move. The limit blocks on the two connecting seats contact the side of the sliding component, completing the initial release of the limit blocks. In this process, the baffle and the gear The third rack produces a shearing effect, so when the sliding part passes over the baffle, the baffle cannot return to its original position. Subsequently, the baffle continues to move and staggers with the limit block. The outer end of the rack three is completely inserted into the receiving hole. The limit block therefore enters the interior of the slide rail, preventing the sliding part from sliding backward, ensuring stable docking between the sliding part and the connecting seat. After completing these steps, the sliding part on the other connecting seat moves according to the same process, thereby realizing the exchange connection between the two sliding parts and the two connecting seats. Finally, the connecting seat carrying the workpiece is successfully connected to the other winch. 3. Through the precise coordination of the gear and rack, the linkage mechanism of the baffle and the limit block ensures the limitation of the freedom of movement of the sliding part. The timely release of the elastic part provides the necessary power, and finally realizes the stable docking of the connecting seat, ensuring the reliability and safety of the entire transposition process. Through this sophisticated design, not only the lifting efficiency is improved, but also the convenience of operation is greatly improved. Through this design, the transfer and circulation of workpieces are more efficient in the collaborative work of multiple winches. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figure 1 As shown, a winch for producing power towers includes a winch (not shown in the figure), a hook 1 and a rope 2. A connecting component 3 is installed between the hook 1 and the rope 2. The connecting component 3 connects the hook and the rope 2 together, and the connecting component 3 further optimizes the convenience of the workpiece during the transfer process.

[0030] like Figures 1-9 As shown, the connecting assembly 3 includes a connecting seat 31, a sliding part 32 and a limiting assembly 33. The bottom of the connecting seat 31 is connected to the chain link between the hook 1, the top of the sliding part 32 is connected to the lifting rope 2, and the sliding part 32 is slidably installed on the connecting seat 31. The sliding of the sliding part 32 is limited by the limiting assembly 33 to ensure safety and stability during the lifting process.

[0031] The top of the connecting seat 31 is provided with two parallel slide rails 311. The front end of the slide rail 311 passes through the front end surface of the connecting seat 31. The sliding part 32 slides and fits in the slide rail 311. In this way, the workpiece can be transferred by moving the sliding part 32. The design of the slide rail 311 makes the transfer process simple and direct, and also ensures the stability of the transfer. The connecting seat 31 is provided with a guide rod 312 in the left and right directions near the front end surface. The limit assembly 33 is installed on the guide rod 312 so that it can slide along the guide rod 312. The connecting seat 31 is provided with a magnetic component for connecting with the front end surface of the other connecting seat 31. The magnetic component is attracted by the magnetic component to ensure that the two winches are connected quickly and accurately during docking. The front end surface of the connecting seat 31 is provided with a docking hole, and a docking rod adapted to the docking hole is fixedly installed on the front end surface of the connecting seat 31. The two connecting seats 31 are guided by the docking hole and the docking rod, thereby achieving stable docking. The magnetic attraction assembly is composed of two magnets 313, which are designed to be bilaterally symmetrical (such as Figure 6 As shown in the figure, their magnetic poles are different. This unique design ensures that the two magnetic components can be precisely docked when docked. It is precisely because of this precise docking mechanism that the two docking seats can fit together perfectly, thus ensuring the stability and reliability of the entire system.

[0032] The limit assembly 33 includes two limit blocks 331 and a trigger assembly. The two limit blocks 331 are symmetrically arranged. A guide hole that matches the guide rod 312 is opened on the limit block 331, so that the two limit blocks 331 are slidably connected to the guide rod 312. The surface of the guide rod 312 is coated with a wear-resistant material to extend the service life and reduce friction resistance to ensure that the limit blocks 331 slide smoothly. The limit blocks 331 are controlled to slide along the guide rod 312 by the trigger assembly so that the limit blocks 331 can slide into and out of the slide rail 311. When transporting a workpiece, the limit blocks 331 limit the sliding part 32 from escaping the slide rail 311 (such as Figure 6 As shown, this prevents the sliding portion 32 from accidentally disengaging. When the two connecting seats 31 are connected, the trigger assembly controls the two limit blocks 331 to slide out of the slide rails 311, causing the sliding portion 32 on one connecting seat 31 to slide into the slide rail 311 of the other connecting seat 31. The sliding portion 32 on the other connecting seat 31 then slides into the slide rail 311 of the first connecting seat 31, completing the interchange and the transfer of workpieces between the two winches. This avoids removing workpieces from one winch and then hanging them on the other winch, ensuring efficient transfer and reducing potential damage. This design significantly improves the efficiency and safety of lifting operations.

[0033] The trigger assembly includes two racks 332, two elastic members 333, two gears 334, rack 2 335, rack 336 and a limiting member. The two racks are fixedly connected to the two limit blocks 331 respectively. The two elastic members 333 (preferably torsion springs) are respectively installed on the two gears 334, and the two elastic members 333 are connected to the connecting seat 31 to provide a reset force. The rack 1 332 is parallel to the guide rod 312, and the rack 2 335 and rack 3 336 are both slidably installed in the connecting seat 31, and the two are parallel. The front ends of the rack 2 335 and rack 3 336 protrude from the front end surface of the connecting seat 31, and the rack 2 335 and rack 3 336 are at the same height. The rack 332 and the rack 1 332 are staggered in vertical height, and the rack 2 335 and the rack 1 332 are perpendicular to each other in the horizontal projection plane. The rack 1 332 and the rack 2 335 are both engaged with the gear 334, and the other rack 1 332 and the rack 3 336 are engaged with the other gear 334. When the two connecting seats 31 approach each other, the rack 2 335 and the rack 3 336 abut against each other, so that the rack 2 335 and the rack 3 336 drive the gear 334 to rotate, thereby driving the rack 1 332 to move, causing the elastic member 333 to deform and accumulate elastic potential energy, while gradually pushing the limit block 331 out of the slide rail 311. When the two connecting seats 31 are docked, the limit block 331 no longer restricts the movement of the sliding portion 32. The outer end of the second rack 335 is provided with a receiving hole, the length of which is not less than the maximum length of the second rack 335 protruding from the connecting seat 31, and the length of the docking rod is greater than twice the maximum length of the second rack 335 protruding from the connecting seat 31, thereby ensuring that when the two docking seats are docked, the docking rod is first inserted into the docking hole to avoid deviation in the docking between the second rack 335 and the third rack 336. The outer end of the third rack 336 is smaller in size and fits into the receiving hole, and a limiting member is installed on the outside of the receiving hole to limit the insertion of the third rack 336 into the receiving hole. When the two winches are ready to dock, as the connecting seat 31 gradually approaches, the front end of the rack 2 335 will first contact the limiting member. This contact will push the rack 336 to move along its installation direction until it is completely retracted into the connecting seat 31. After that, the sliding portion 32 slides along the slide rail 311, and the limiting member will be overcome, allowing the outer end of the rack 336 to enter the receiving hole. This action no longer restricts the rotation of the gear 334, and the elastic member 333 releases its elastic potential energy, thereby moving the rack 1 332 and pushing the limiting block 331 to slide along the guide rod 312 and gradually enter the slide rail 311. The movement of the rack 1 332 drives the gear 334 to rotate, causing the outer end of the rack 3 336 to enter the receiving hole, thereby allowing the rack 3 336 and the rack 2 335 to be plugged into each other. The limiting member includes a baffle 337 and a reset member 338. The baffle 337 is mounted on the front end of the second rack 335 by sliding up and down, effectively blocking the third rack 336 from entering the receiving hole. The baffle 337 is provided with a through hole that is compatible with the outer end of the third rack 336. The reset member 338 (preferably a spring) is mounted between the baffle 337 and the second rack 335. In the initial state, the through hole and the receiving hole are staggered. The top of the baffle 337 extends into the slide rail 311. The top of the baffle 337 is wedge-shaped, that is, the front and rear sides of the top of the baffle 337 are both inclined surfaces. When the rack 2 335 and the rack 336 are fully retracted into the connecting seat 31, and the rack 336 abuts against the baffle 337, there is a gap between the limit block 331 and the sliding portion 32 on the front projection surface. When the sliding portion 32 slides along the slide rail 311, the sliding portion 32 abuts against the inclined surface, so that the baffle 337 gradually presses the reset member 338 downward, causing the baffle 337 to move downward, and the through hole coincides with the receiving hole. The elastic member 333 releases the elastic potential energy to rotate the gear 334, so that the rack 336 is smoothly inserted into the receiving hole for a distance, and the rack 336 and the rack 2 335 move, so that the limit blocks 331 on the two connecting seats 31 abut against the side surfaces of the sliding portion 32. After the initial release of the limit block 331 is completed, the baffle 337 and the rack three 336 are sheared. Therefore, when the sliding part 32 passes over the baffle 337, the baffle 337 cannot be reset. Finally, the baffle 337 continues to move and is staggered with the limit block 331. The outer end of the rack three 336 is fully inserted into the accommodating hole, so that the limit block 331 enters the slide rail 311, blocking the sliding part 32 from sliding back, ensuring the stable docking of the sliding part 32 and the connecting seat 31. Afterwards, 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 is connected to the other winch with the workpiece.

[0034] The working steps are as follows: 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; S2. Adjust the height of the first winch so that the connecting assembly 3 is aligned with the connecting assembly 3 of the second winch; S3, move the connecting assembly 3 on the second winch so that the docking rod on the connecting seat 31 is inserted into the docking hole; S4, the two connecting seats 31 are gradually brought closer together, the rack 2 335 and the rack 3 336 are offset against each other, thereby rotating the gear 334. The rotation of the gear 334 causes the rack 1 332 to move, driving the limit block 331 to slide out of the slide rail 311, and no longer restricting the sliding of the sliding part 32 (the state is as follows Figure 1 shown); S5. Push the sliding portion 32 on the empty winch to slide, causing the sliding portion 32 to abut against the baffle 337. The baffle 337 moves downward, and the through hole on the baffle 337 gradually coincides with the receiving hole. The rack 336 is smoothly inserted into the receiving hole for a distance. S6. Continue to push the sliding portion 32 until it completely passes through the stop block 331. The elastic member 333 releases its elastic potential energy to rotate the gear 334, so that the rack 336 is completely inserted into the receiving hole. The stop block 331 enters the slide rail 311, preventing the sliding portion 32 from sliding back. S7, controlling the second winch to retract the rope upward for a short distance, so that the second winch exerts a certain lifting force on the workpiece; S8, slide the other sliding part 32 into the slide rail 311 of the connecting seat 31 without the workpiece, repeat the above steps to ensure that the sliding parts 32 on the two connecting seats 31 are stably connected to the limit block 331 (the state is as follows Figure 5 shown); S9. Confirm that the sliding parts 32 on the two connecting seats 31 are completely connected with the limiting blocks 331 to ensure a stable connection; S10, overcoming the magnetic force to separate the two connecting seats 31, thereby completing the position change and transferring the workpiece to the second winch.

[0035] In the above process, the first winch and the second winch alternately apply tension, so that the sliding part 32 can be easily pushed, avoiding the sliding part 32 from being subjected to a large tension and being inconvenient to slide. At the same time, this design also avoids the sliding part 32 from being stuck or damaged when subjected to excessive tension, further improving the service life and safety of the winch. In specific operations, the staff only needs to follow the above steps to easily complete the lifting and circulation of the workpiece, greatly improving work efficiency and accuracy. In general, the present invention successfully solves the problems existing in traditional winches in the process of workpiece transportation and circulation, and brings a more convenient, efficient and safe solution to lifting operations.

[0036] Working principle: When transporting workpieces, the limit block 331 limits the sliding part 32 from escaping the slide rail 311, thereby preventing the sliding part 32 from accidentally escaping. When the two connecting seats 31 are connected, the rack 2 335 and the baffle 337 on the rack 3 336 are abutted, so that the rack 2 335 and the rack 3 336 drive the gear 334 to rotate, and then drive the rack 1 332 to move, so that the elastic member 333 is deformed to accumulate elastic potential energy, and at the same time, the limit block 331 is gradually pushed out of the slide rail 311, and the two connecting seats 31 are connected. When the stop block 331 no longer restricts the movement of the sliding portion 32, in the subsequent operation process, the sliding portion 32 slides along the slide rail 311. At this time, the sliding portion 32 is in close contact with the inclined surface. Through this contact, the baffle 337 gradually presses the reset member 338 downward, causing the baffle 337 to move downward. As the baffle 337 descends, the through hole and the receiving hole are gradually aligned, and the elastic member 333 releases its stored elastic potential energy. This energy release causes the gear 334 to start rotating, and the rotation of the gear 334 Drive rack three 336 to move forward, rack three 336 is inserted into the accommodating hole for a distance, and with the movement of rack three 336, rack two 335 also starts to move, and the limit blocks 331 on the two connecting seats 31 contact the side surfaces of the sliding portion 32, completing the initial release of the limit blocks 331. In this process, baffle 337 and rack three 336 have a shearing effect. Therefore, when the sliding portion 32 passes over the baffle 337, the baffle 337 cannot return to its original position. Subsequently, the baffle 337 continues to move, and The limit block 331 is staggered, and the outer end of the rack three 336 is fully inserted into the receiving hole. The limit block 331 therefore enters the interior of the slide rail 311, preventing the sliding part 32 from sliding back, ensuring stable docking between the sliding part 32 and the connecting seat 31. After completing these steps, 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 successfully completes the connection with the other winch with the workpiece.
