Description

Technical Field

[0001] This invention relates to the field of elevator compensation chain technology, specifically to a low-noise elevator compensation chain structure and its noise reduction method. Background Technology

[0002] Elevators are becoming increasingly common in people's lives, and people are relying on them more and more. The elevator compensation chain plays a crucial role in the operation of elevators.

[0003] The existing elevator compensation chain has the following defects:

[0004] 1. In patent document US3768596A, "elastic spacers provided for alternating links of an elevator compensating chain keep the links fully extended, thereby eliminating the rattling sound of the chain. The cross-sectional dimensions of the spacers exceed the cross-sectional dimensions of the links to eliminate noise generated by the links impacting components in the shaft. The Y-type connection with the car and counterweight allows the use of a single compensating chain without interfering with the buffer." The compensating chain body described above lacks an internal protective structure, cannot improve the wear resistance of the compensating chain, has too much exposed metal part, and produces a large amount of noise when it collides.

[0005] 2. In patent document KR102022057B1, "a guiding device for an elevator compensation chain is described. The guiding device for the elevator compensation chain includes a fixed member fixed to a support frame installed near the elevator compensation chain, and a guide roller that rotates when in contact with the compensation chain. The guide roller is connected to the fixed member and compensates for the compensation. A roller unit is also described, which is configured to elastically rotate about a connection point with the fixed member to disperse the impact energy generated when the chain collides with another chain." The aforementioned compensation chain lacks a silent guiding structure, leading to collisions during chain movement.

[0006] 3. In patent document WO2017016110A1, it is stated that "This invention discloses an elevator balance compensation chain with steel balls, including chain links (1), a galvanized layer (2), a PVC outer layer (3), and steel balls (4). The chain links (1) are interlocked to form a long chain. The zinc layer (2) is adsorbed on the surface of the chain links (1), and the surface of the zinc layer is smooth, uniform, and fine. The PVC outer layer (3) is uniformly coated on the surface of the galvanized layer (2) to maintain the form of a metal chain. The steel balls (4) are uniformly distributed in the PVC outer layer (3). The elevator balance compensation chain with steel balls can effectively reduce elevator operating noise, has good flexibility, is not easy to crack, has a long service life, and high strength." However, the compensation chain lacks a guiding structure displacement adjustment function inside, and when the compensation chain is close to the wall, it will collide with the wall, causing noise and increasing the noise level.

[0007] 4. In patent document WO2016192291A1, "This invention discloses a balance compensation chain for a fully plastic elastic flame-retardant elevator, including a metal chain (3) covered by a covering layer (2). The covering layer is provided with a sheath (1). The metal chain (3) includes two sub-metal chains. The two sets of metal chains are a first set of metal chains (31) and a second set of metal chains (32), and the second set of metal chains (32) is wound and fixed on the first set of metal chains (31)." The above document lacks an adjustment structure, making it impossible to adjust the height of the guiding structure, and the applicability of the device is relatively low. Summary of the Invention

[0008] The purpose of this invention is to provide a low-noise elevator compensation chain structure and its noise reduction method to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a low-noise elevator compensation chain structure, comprising a steel wire chain, a buffer layer installed on the outer side of the steel wire chain, a reinforcing wire installed on the outer side of the buffer layer, a wear-resistant layer installed on the outer side of the reinforcing wire, connecting components installed on the outer sides of both ends of the wear-resistant layer, a safety component installed on the outer side of the wear-resistant layer, and a guide component movably installed at the bottom outer side of the wear-resistant layer.

[0010] The connecting assembly includes an assembly tube installed on the outer sides of both ends of the wear-resistant layer. A connecting rod is installed through the inner wall of the assembly tube. The connecting rod passes through the inner side of the steel wire chain, the buffer layer, the reinforcing wire, and the wear-resistant layer. A tightening member is installed on the outer side of the connecting rod by means of a thread. The tightening member abuts against one side of the assembly tube. A U-shaped ring is installed at the top end of the assembly tube.

[0011] Preferably, the safety component includes two sets of arc-shaped plates installed on the outer side of the wear-resistant layer. Assembly plates are installed on the front end and front side of the arc-shaped plates. A tensioning rod is movably installed through the inner side of the two sets of assembly plates. A fixing ring is installed on the outer side of each set of arc-shaped plates. A first connecting ring is movably connected to the outer side of the fixing ring. An installation ring is connected to one end of the first connecting ring. A safety rope is installed at one end of the installation ring. Installation rings are provided at both ends of the safety rope.

[0012] Preferably, the other end of the safety rope is connected to a second connecting ring via an installation ring, and a support ring is movably connected to the top of the second connecting ring, with an installation plate mounted on the top of the support ring.

[0013] Preferably, the bottom of the mounting plate is connected to two sets of support rings, and mounting screws are installed through the inner side of the mounting plate. One set of mounting plates is installed on the counterweight by mounting screws, and the other set is installed on the bottom of the elevator car by mounting screws. A connecting seat is installed at the bottom of the mounting plate, and the connecting seat is located between the two sets of support rings. A movable ring is connected to the bottom end of the connecting seat, and a support member is installed at the bottom end of the movable ring. Two sets of support rods are installed on the inner side of the support member, and the two sets of support rods pass through the inner side of the U-shaped ring.

[0014] Preferably, the guiding component includes a support frame, with guide grooves on the front and back sides of the support frame, and a fixing plate installed on the inner front and back sides of the support frame. A bidirectional lead screw is installed through the inner side of the fixing plate, and a servo motor is installed at one end of the bidirectional lead screw. The servo motor is installed on one side of the fixing plate.

[0015] Preferably, a movable ring is movably mounted on the outer side of the bidirectional lead screw via a thread. The movable ring is located inside the guide groove, and a support frame is installed between the movable rings. The support frame moves horizontally left and right inside the support frame.

[0016] Preferably, a buffer rod is installed on the inner wall of the support frame, a support plate is installed at one end of the buffer rod, a support shaft is installed on the inner side of the support plate, a rotating roller is movably installed on the outer side of the support shaft, a silent wheel is installed on the outer side of the rotating roller, and four sets of silent wheels cooperate to form a limiting structure to guide the movement of the wear-resistant layer.

[0017] Preferably, lifting plates are installed on both sides of the support frame, a telescopic rod is installed at the bottom of the lifting plate, a base plate is installed at the bottom end of the telescopic rod, a through plate is installed at the front and rear ends of the base plate, and a ground nail is installed through the inner side of the through plate.

[0018] Preferably, the noise reduction method for this elevator compensation chain structure is as follows:

[0019] S1. One set of mounting plates is installed on the counterweight with mounting screws, and the other set is installed on the bottom of the elevator car with mounting screws to ensure the stability of the mounting plates. During electric operation, the two sets of mounting plates move back and forth up and down.

[0020] S2. Two sets of mounting plates drive the steel wire chain, buffer layer, reinforcing wire, and wear-resistant layer to move within the elevator shaft. The steel wire chain, made of wound metal wire, is used to increase the weight of the supplementary chain. The steel wire chain fixes the outer buffer layer, which is made of rubber material. The buffer layer supports the outer reinforcing wire. At the same time, the wear-resistant layer works with the buffer layer to fix the reinforcing wire. The reinforcing wire strengthens the compensation chain and prevents the supplementary chain from breaking. The wear-resistant layer is installed on the outside of the compensation chain. The wear-resistant layer is made of wear-resistant rubber material that wraps around the compensation chain. The wear-resistant material isolates the metal material in the compensation chain from the wall, reducing noise generation in the nozzle and achieving noise reduction during elevator operation.

[0021] S3. During the operation of the compensation chain, it will pass through the inner side of the support frame. The support frame fixes the inner buffer rod, and the buffer rod supports the support plate at one end. The support plate is U-shaped and supports the inner support shaft. The support shaft limits the rotation of the outer rotating roller, ensuring that the rotating roller can rotate smoothly. The rotating roller rotates outside the support shaft and supports the outer silent wheel, ensuring the stability of the silent wheel. The silent wheel is made of rubber material. The four sets of silent wheels smoothly guide the movement of the compensation chain. The movement of the supplementary chain is limited by the four sets of silent wheels, reducing the noise generated by the shaking of the supplementary chain. At the same time, the buffer rod buffers the silent wheel.

[0022] S4. When using the supplementary chain, the user controls the servo motor to run. The servo motor drives the bidirectional lead screw at the output end to rotate. The rotation of the bidirectional lead screw drives the outer moving ring to move. The moving ring moves inside the guide groove. The guide ring moves to the support frame. The two sets of support frames move closer or further apart under the drive of the bidirectional lead screw. Adjusting the position of the silent wheels inside the support frame makes it easy to adjust the distance of the silent wheels inside the guide assembly according to different situations. This avoids the guide structure spacing being too large, causing the compensation chain to be too close to the wall and collide. It also reduces the wear of the compensation chain and achieves the purpose of noise reduction.

[0023] Preferably, step S4 further includes the following steps:

[0024] S41. The through plate is fixed to the ground by embedded nails. The through plate is used to fix the base plate. The base plate supports the top telescopic rod. The telescopic rod supports the top lifting plate. The lifting plate supports the support frame. The height of the support frame needs to be adjusted to adjust the height of the guide components.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention features a wear-resistant layer and a buffer layer. A steel wire chain secures the outer buffer layer, which is made of rubber material. The buffer layer supports the outer reinforcing wires, while the wear-resistant layer and buffer layer work together to secure the reinforcing wires. The reinforcing wires strengthen the compensation chain and prevent breakage. The wear-resistant layer is installed on the outer side of the compensation chain and is made of wear-resistant rubber material that wraps around the compensation chain. This wear-resistant material isolates the metal material in the compensation chain from the wall, reducing noise generation in the nozzles and achieving noise reduction during elevator operation.

[0027] 2. This invention features a support plate and silent wheels. The support plate is U-shaped and supports the inner support shaft, which in turn limits the rotation of the outer rotating roller, ensuring its smooth rotation. The rotating roller rotates outside the support shaft and supports the outer silent wheel, ensuring its stability. The silent wheel is made of rubber. Four sets of silent wheels smoothly guide the movement of the compensation chain. The four sets of silent wheels limit the movement of the supplementary chain, reducing the noise generated by the chain's swaying. Simultaneously, the buffer rod cushions the silent wheels.

[0028] 3. This invention utilizes a bidirectional lead screw, driven by a servo motor. The rotation of the bidirectional lead screw causes the outer moving ring to move, which moves within the guide groove. The guide ring then moves to the support frame, causing the two support frames to move closer or further apart under the influence of the bidirectional lead screw. This adjusts the position of the silent wheels inside the support frame, allowing for adjustments to the distance between the silent wheels in the guide assembly according to different situations. This prevents excessive spacing between the guide structures, which could cause the compensation chain to be too close to the wall, resulting in a collision. This also reduces wear on the compensation chain and achieves noise reduction.

[0029] 4. This invention features a telescopic rod installed at the bottom, which supports the top telescopic rod. The telescopic rod supports the top lifting plate, which in turn supports the support frame. The height of the support frame needs to be adjusted to adjust the height of the guide component, allowing the guide component to adapt to different situations. Attached Figure Description

The steel wire chain 1, buffer layer 2, reinforcing wire 3, and wear-resistant layer 4 move within the elevator shaft. The steel wire chain 1 is made of wound metal wires to increase the weight of the compensation chain. The steel wire chain 1 fixes the outer buffer layer 2, which is composed of rubber material. The buffer layer 2 supports the outer reinforcing wire 3, while the wear-resistant layer 4 cooperates with the buffer layer 2 to support the reinforcing wire. 3. The reinforcing wire 3 is used to strengthen the compensation chain and prevent it from breaking. The wear-resistant layer 4 is installed on the outside of the compensation chain. The wear-resistant layer 4 is made of wear-resistant rubber material to wrap the compensation chain. The wear-resistant material isolates the metal material in the compensation chain from the wall, reducing the noise generated in the nozzle and achieving the purpose of noise reduction during elevator operation. Connecting components are installed on both ends of the wear-resistant layer 4. The wear-resistant layer 4 fixes the connecting components. A safety component is installed on the outside of the wear-resistant layer 4 and fixed to the outside of the compensation chain. A guide component is movably installed at the bottom of the outside of the wear-resistant layer 4.

[0043] The connecting assembly includes an assembly tube 5 installed on the outer sides of both ends of the wear-resistant layer 4. A connecting rod 6 is installed through the inner wall of the assembly tube 5. The connecting rod 6 passes through the inner side of the wire chain 1, the buffer layer 2, the reinforcing wire 3, and the wear-resistant layer 4. A tightening member 7 is installed on the outer side of the connecting rod 6 by means of a thread. The tightening member 7 abuts against one side of the assembly tube 5. A U-shaped ring 8 is installed at the top of the assembly tube 5. The assembly tube 5 is fitted onto the outer sides of both ends of the wear-resistant layer 4. The connecting rod 6 passes through the inner wall of the assembly tube 5, and then passes through the inner side of the wire chain 1, the buffer layer 2, the reinforcing wire 3, and the wear-resistant layer 4, connecting the assembly tube 5, the wire chain 1, the buffer layer 2, the reinforcing wire 3, and the wear-resistant layer 4 in series. The connecting rod 6 is tightened by the tightening member 7 to ensure the stability of the connecting rod 6 and improve the tightness of the connection between the assembly tube 5, the wire chain 1, the buffer layer 2, the reinforcing wire 3, and the wear-resistant layer 4.

[0044] The safety assembly includes two sets of arc-shaped plates 9 installed on the outer side of the wear-resistant layer 4. Assembly plates 10 are installed on the front and front sides of the arc-shaped plates 9. A tensioning rod 11 is movably installed through the inner sides of both sets of assembly plates 10. A fixing ring 12 is installed on the outer side of each set of arc-shaped plates 9. A first connecting ring 13 is movably connected to the outer side of each fixing ring 12. One end of the first connecting ring 13 is connected to an installation ring 14. A safety rope 15 is installed at one end of the installation ring 14. Installation rings 14 are provided at both ends of the safety rope 15. The two sets of arc-shaped plates 9 are secured to the outer side of the wear-resistant layer 4, fixing the assembly plates 10. The two sets of assembly plates 10 are aligned, and the tensioning rod 11 passes through the two sets of assembly plates 10, assembling the assembly plates 10 together and ensuring that the assembly plates 10 and the arc-shaped plates 9 are level. The arc-shaped plate 9 is fixed to the outer side of the wear-resistant layer 4, ensuring the stability of the fixing ring 12. The fixing ring 12 is connected to the first connecting ring 13, which is movably connected to the mounting ring 14. The mounting ring 14 is connected to the safety rope 15. The other end of the safety rope 15 is connected to the second connecting ring 16 through the mounting ring 14. The top of the second connecting ring 16 is movably connected to the support ring 17. The top of the support ring 17 is equipped with the mounting plate 18, which fixes the bottom support ring 17. The support ring 17 is connected to the bottom second connecting ring 16, which is movably connected to the mounting ring 14. The mounting ring 14 supports the safety rope 15. If the support structure breaks, the support structure will provide protection during maintenance.

[0045] The bottom of the mounting plate 18 is connected to two sets of support rings 17. Mounting screws 30 are installed through the inner side of the mounting plate 18. One set of mounting plates 18 is installed on the counterweight using mounting screws 30, and the other set is installed on the bottom of the elevator car using mounting screws 30. A connecting seat 19 is installed at the bottom of the mounting plate 18, located between the two sets of support rings 17. A movable ring 20 is connected to the bottom end of the connecting seat 19. A support member 21 is installed at the bottom end of the movable ring 20. Two sets of support rods 22 are installed on the inner side of the support member 21, and these two sets of support rods 22 penetrate the inner side of the U-shaped ring 8. One set of mounting plates 18 is installed on the counterweight using mounting screws 30, and the other set is installed on the bottom of the elevator car using mounting screws 30, ensuring the stability of the mounting plate 18. During electric operation, the two sets of mounting plates 18 reciprocate up and down.

[0046] The guiding assembly includes a support frame 23. Guide grooves 31 are formed on the front and back of the support frame 23. A fixing plate 37 is installed on the inner front and back of the support frame 23. A bidirectional lead screw 38 is threaded through the inner side of the fixing plate 37. A servo motor 40 is installed at one end of the bidirectional lead screw 38 and is mounted on one side of the fixing plate 37. A moving ring 39 is threadedly installed on the outer side of the bidirectional lead screw 38. The moving ring 39 is located inside the guide groove 31. A support frame 25 is installed between the moving rings 39. The support frame 25 moves horizontally left and right inside the support frame 23. The guide grooves 31 are formed on the front and back of the support frame 23. The support frame 23 fixes the fixing plate 37 on the front and back, facilitating the fixing plate 37's movement of the servo motor 40. The servo motor 40 and the bidirectional lead screw 38 provide support. When the supplementary chain is in use, the user controls the servo motor 40 to run, which drives the bidirectional lead screw 38 at the output end to rotate. The rotation of the bidirectional lead screw 38 drives the outer moving ring 39 to move. The moving ring 39 moves inside the guide groove 31 and moves to the support frame 25. The two sets of support frames 25 move closer or further apart under the drive of the bidirectional lead screw 38. The position of the silent wheel 28 inside the support frame 25 can be adjusted to facilitate the adjustment of the distance of the silent wheel 28 inside the guide assembly according to different situations. This avoids the guide structure spacing being too large, which would cause the compensation chain to be too close to the wall and collide. This reduces the wear of the compensation chain and also achieves the purpose of noise reduction.

[0047] A buffer rod 26 is installed on the inner wall of the support frame 25. A support plate 27 is installed at one end of the buffer rod 26. A support shaft 32 is installed on the inner side of the support plate 27. A rotating roller 33 is movably installed on the outer side of the support shaft 32. A silent wheel 28 is installed on the outer side of the rotating roller 33. The four sets of silent wheels 28 cooperate to form a limiting structure to guide the movement of the wear-resistant layer 4. During the operation of the compensation chain, it will pass through the inner side of the support frame 25. The support frame 25 fixes the buffer rod 26 on the inner side. The buffer rod 26 supports the support plate 27 at one end. The support plate 27 is U-shaped. The support plate 27 supports the inner support shaft 32, and the support shaft 32 limits the rotation of the outer rotating roller 33, ensuring that the rotating roller 33 can rotate smoothly. The rotating roller 33 rotates outside the support shaft 32 and supports the outer silent wheel 28, ensuring the stability of the silent wheel 28. The silent wheel 28 is made of rubber material. The four sets of silent wheels 28 smoothly guide the movement of the compensation chain. The movement of the supplementary chain is limited by the four sets of silent wheels 28, reducing the noise generated by the shaking of the supplementary chain. At the same time, the silent wheel 28 is buffered by the buffer rod 26.

[0048] Lifting plates 24 are installed on both sides of the support frame 23. A telescopic rod 29 is installed at the bottom of the lifting plate 24. A base plate 34 is installed at the bottom end of the telescopic rod 29. Through plates 35 are installed at the front and rear ends of the base plate 34. Ground nails 36 are installed through the inner side of the through plate 35. The through plate 35 is fixed to the ground by the ground nails 36 and the base plate 34 is fixed by the through plate 35. The base plate 34 supports the telescopic rod 29 at the top. The telescopic rod 29 supports the lifting plate 24 at the top. The lifting plate 24 supports the support frame 23. The height of the support frame 23 needs to be adjusted to adjust the height of the guide component, so that the guide component can adapt to different situations.

[0049] Furthermore, the noise reduction method for this elevator compensation chain structure is as follows:

[0050] S1. One set of mounting plates 18 is installed on the counterweight by mounting screws 30, and another set is installed at the bottom of the elevator car by mounting screws 30 to ensure the stability of the mounting plates 18. During the electric operation, the two sets of mounting plates 18 move up and down reciprocally.

[0051] S2. Two sets of mounting plates 18 drive the steel wire chain 1, buffer layer 2, reinforcing wire 3 and wear-resistant layer 4 to move. The steel wire chain 1, buffer layer 2, reinforcing wire 3 and wear-resistant layer 4 move in the elevator shaft. The steel wire chain 1 is made of wound metal wire and is used to increase the weight of the supplementary chain. The steel wire chain 1 fixes the outer buffer layer 2. The buffer layer 2 is made of rubber material and supports the outer reinforcing wire 3. At the same time, the wear-resistant layer 4 works with the buffer layer 2 to fix the reinforcing wire 3. The reinforcing wire 3 strengthens the strength of the compensation chain and prevents the supplementary chain from breaking. The wear-resistant layer 4 is installed on the outside of the compensation chain. The wear-resistant layer 4 is made of wear-resistant rubber material to wrap the compensation chain. The wear-resistant material isolates the metal material in the compensation chain from the wall, reduces the noise generated in the nozzle, and achieves the purpose of noise reduction when the elevator is running.

[0052] S3. During the operation of the compensation chain, it will pass through the inner side of the support frame 25. The support frame 25 fixes the inner buffer rod 26, and the buffer rod 26 supports the support plate 27 at one end. The support plate 27 is U-shaped and supports the inner support shaft 32. The support shaft 32 limits the rotation of the outer rotating roller 33, ensuring that the rotating roller 33 can rotate smoothly. The rotating roller 33 rotates outside the support shaft 32 and supports the outer silent wheel 28, ensuring the stability of the silent wheel 28. The silent wheel 28 is made of rubber material. The four sets of silent wheels 28 smoothly guide the compensation chain to move. By limiting the movement of the supplementary chain through the four sets of silent wheels 28, the noise generated by the shaking of the supplementary chain is reduced. At the same time, the silent wheel 28 is buffered by the buffer rod 26.

[0053] S4. When the supplementary chain is in use, the user controls the servo motor 40 to run. The servo motor 40 drives the bidirectional lead screw 38 at the output end to rotate. The rotation of the bidirectional lead screw 38 drives the outer moving ring 39 to move. The moving ring 39 moves inside the guide groove 31. The guide ring 39 moves to the support frame 25. The two sets of support frames 25 move closer or further apart under the drive of the bidirectional lead screw 38. The position of the silent wheel 28 inside the support frame 25 is adjusted to facilitate the adjustment of the distance of the silent wheel 28 inside the guide component according to different situations. This avoids the guide structure spacing being too large, causing the compensation chain to be too close to the wall and collide. This reduces the wear of the compensation chain and achieves the purpose of noise reduction.

[0054] Step S4 further includes the following steps:

[0055] S41. The through plate 35 is fixed to the ground by the buried nails 36. The through plate 35 is used to fix the base plate 34. The base plate 34 supports the top telescopic rod 29. The telescopic rod 29 supports the top lifting plate 24. The lifting plate 24 supports the support frame 23. The height of the support frame 23 needs to be adjusted to adjust the height of the guide component.

[0056] Working Principle: One set of mounting plates 18 is installed on the counterweight using mounting screws 30, and the other set is installed at the bottom of the elevator car using mounting screws 30, ensuring the stability of the mounting plates 18. During electric operation, the two sets of mounting plates 18 reciprocate up and down, driving the steel wire chain 1, buffer layer 2, reinforcing wire 3, and wear-resistant layer 4 to move. The steel wire chain 1, buffer layer 2, reinforcing wire 3, and wear-resistant layer 4 move within the elevator shaft. The steel wire chain 1, made of wound metal wire, is used to increase the weight of the supplementary chain. The steel wire chain 1 fixes the outer buffer layer 2, which is made of rubber material. The buffer layer 2 supports the outer reinforcing wire 3, while the wear-resistant layer 4, in conjunction with the buffer layer 2, secures the reinforcing wire 3. The reinforcing wire 3 strengthens the compensating chain to prevent breakage. A wear-resistant layer 4 is installed on the outer side of the compensating chain, wrapped in wear-resistant rubber material. This layer isolates the metal parts of the compensating chain from the wall, reducing noise from the nozzles and achieving noise reduction during elevator operation. During operation, the compensating chain passes through the inner side of the support frame 25. The support frame 25 fixes the inner buffer rod 26, which in turn supports a support plate 27 at one end. The support plate 27 is U-shaped and supports the inner support shaft 32. The support shaft 32 provides limiting support for the outer rotating roller 33, ensuring smooth rotation of the rotating roller 33. The rotating roller 33 rotates outside the support shaft 32, supporting the silent wheel 28 on the outside to ensure its stability. The silent wheel 28 is made of rubber material. The four sets of silent wheels 28 smoothly guide the compensation chain to move. The four sets of silent wheels 28 limit the movement of the supplementary chain, reducing the noise generated by the shaking of the supplementary chain. At the same time, the buffer rod 26 buffers the silent wheel 28. When the supplementary chain is in use, the user controls the servo motor 40 to run. The servo motor 40 drives the bidirectional lead screw 38 at the output end to rotate. The rotation of the bidirectional lead screw 38 drives the outer moving ring 39 to move. The moving ring 39 moves inside the guide groove 31. The guide ring 39 reaches the support frame 25 to move. The two sets of support frames 25 move closer or separate under the drive of the bidirectional lead screw 38, adjusting the position of the silent wheels 28 inside the support frame 25. This allows for easy adjustment of the distance between the silent wheels 28 inside the guide assembly according to different situations, preventing excessive spacing between the guide structures and causing the compensation chain to be too close to the wall, thus reducing wear on the compensation chain and achieving noise reduction. The through plate 35 is fixed to the ground by the embedded nails 36, and the through plate 35 is used to fix the base plate 34. The base plate 34 supports the top telescopic rod 29, which in turn supports the top lifting plate 24. The lifting plate 24 supports the support frame 23. The height of the support frame 23 needs to be adjusted to adjust the height of the guide assembly.
