Description

Technical Field

[0001] This invention relates to the field of elevator balance compensation chain manufacturing technology, specifically to an automatic chain tensioning and torque-reducing device for elevator balance compensation chains. Background Technology

[0002] Key technical indicators of elevator balance compensation chains include straightness and operational stability. The verticality of the chain links is crucial to the smooth operation of the compensation chain. In existing compensation chain production equipment, the chain links are manually loaded and the chain links are manually adjusted by visual inspection. This process is time-consuming, results in gaps in the chain links due to lack of tension, and makes the compensation chain prone to abnormal noise after production. Furthermore, the unclear adjustment of the torque can cause the compensation chain to easily flip during operation, thus losing its balance compensation function.

[0003] The existing tensioning and torque-reducing devices have the following drawbacks:

[0004] 1. In the patent document JP2023001412A, the main consideration is to supply lubricating oil to the chain links by setting an oil core component. However, it does not take into account the problem that the existing elevator balance compensation chain has a slow rate of manual torque removal during production, which makes it less practical.

[0005] 2. In the patent document KR1020190101073A, the main consideration is how to disperse the impact energy generated when the guide rod collides with the compensation chain. However, it does not take into account that the existing elevator balance compensation chain is not convenient to adjust the space of the chain link guide clamping module according to the size of the chain link during production.

[0006] 3. In patent document KR101921454B1, the main consideration is how to adjust the rotation angle of the guide device, but the problem of poor convenience of tension adjustment during production of existing elevator balance compensation chains is not taken into account.

[0007] 4. In patent document CN217263886U, the main consideration is how to reduce the use of manpower in the packaging process, reduce the difficulty of operation, and improve production efficiency. However, it does not take into account that the existing elevator balance compensation chain is not convenient to adjust the tension of different sizes according to the different chain link sizes during production, and has poor flexibility. Summary of the Invention

[0008] The purpose of this invention is to provide an automatic chain tensioning and torque-reducing device for elevator balance compensation chains, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an automatic chain tensioning and torque-removing device for elevator balance compensation chain, comprising a lower frame and an automatic chain link placement and torque-removing module, wherein the automatic chain link placement and torque-removing module is used to remove the torque of the compensation chain links, and the automatic chain link placement and torque-removing module is assembled from a speed regulating motor, a base plate, an eccentric wheel, an adjusting screw, a centering shaft, a chain guide plate, and a slot.

[0011] The top of the chain plate has symmetrically arranged slots for placing the compensation chain.

[0012] Preferably, a middle frame is welded to the top of the lower frame, and an upper frame is welded to the top of the middle frame. A bracket arranged in a front-to-back configuration is welded to one outer wall of the upper frame, and the bracket has an "L"-shaped structure. The bottom of the bracket is connected to the top of the middle frame. A chain link guide clamping module is installed on the top of the bracket, and the chain link guide clamping module is used to clamp and guide the chain link. The chain link guide clamping module is assembled into a complete device by a guide rail, a slider, a fixing block, and an ACE gas spring. The tops of the two sets of brackets are bolted with symmetrically arranged guide rails and front-to-back fixing blocks, and the surfaces of the two sets of fixing blocks that are close to each other are connected to the front and back of the two sets of guide rails, respectively. An ACE gas spring is installed inside the two sets of fixing blocks. A slider is installed at the output end of the ACE gas spring, and the slider is inside the guide rail. The ACE gas spring is used to adjust the movement distance of the slider in the guide rail according to the chain link of different specifications.

[0013] Preferably, a chain tension adjustment module is installed on the top of the lower frame, and the chain tension adjustment module is used to adjust the tension of the chain. The chain tension adjustment module is located on one side of the chain automatic placement and de-twisting module and on the lower side of the upper frame. The chain tension adjustment module includes a storage plate that is bolted to the lower frame. The top of both sets of storage plates is provided with a through hole. The top of both sets of storage plates is provided with symmetrically arranged sliding guide blocks. The through hole is located in the middle of the two sets of sliding guide blocks. The surfaces of the front and rear sets of sliding guide blocks that are close to each other are provided with a slot. The slot is engaged with a limit plate. The top of both sets of sliding guide blocks is fixed with a baffle by bolts. The baffle is located above the limit plate and is used to limit the limit plate. The front of the front and rear sets of limit plates is provided with a storage hole and a storage groove. The storage groove is located below the storage hole.

[0014] Preferably, a counterweight assembly is installed at the bottom of the chain link tension adjustment module, and the counterweight assembly is used to adjust the counterweight of the chain link tension adjustment module. The counterweight assembly includes a suspension rod, a first support block, a second placement hole, a connecting rod, and counterweight blocks. The suspension rod is fixed inside the placement groove by bolts, and one end of the suspension rod passes through the inside of the jack from the bottom of the placement plate and extends into the inside of the lower frame. The bottoms of the two suspension rods are both welded with the first support block. The second placement holes are penetrated through the surfaces of the two first support blocks close to each other. The connecting rod is fitted and installed inside the two second placement holes. The outer surface of the connecting rod is sleeved with evenly arranged counterweight blocks, and the counterweight blocks are used to increase the downward pulling force of the downward suspension rod.

[0015] Preferably, the adjusting screw is used to push the chain arranging plate to rotate on the centering shaft. The first slot is in a "U" - shaped structure. The adjusting screw is located in front of the centering shaft, and the eccentric wheel is located on one side of the centering shaft. The shaft parts for fixing the chain arranging plate and the adjusting screw are both located in the middle of the two first slots;

[0016] After the two sliders are combined together, there is a "mouth" - shaped gap in the middle. The lower frame, the middle frame, the upper frame, and the bracket are made of steel pipes or angle steels. The lower frame, the middle frame, the upper frame, and the bracket can bear the weight of all components and the operation requirements;

[0017] The limiting plate is in a "T" - shaped structure. The bottom size of the limiting plate is smaller than the size of the jack. Under the action of gravity, the limiting plate can slide downward in the card slot. The chain link tension adjustment module is located inside the middle frame;

[0018] The counterweight block is in an inverted "U" - shaped structure. Increasing the number of counterweight blocks placed on the connecting rod can make the suspension rod pull the limiting plate downward to move in the card slot.

[0019] Preferably, chain link guiding roller assemblies are installed on the tops of the upper frame and the middle frame and inside the chain link tension adjustment module. The chain link guiding roller assemblies are used to ensure the correct running direction of the chain link. There are two sets of chain link guiding roller assemblies on the upper frame. The chain link guiding roller assembly is assembled by a bearing seat, a main shaft, a chain link orientation wheel, and a positioning sleeve set into a complete set of devices. The bearing seats are installed inside the two first placement holes and on the tops of the upper frame and the middle frame. The main shafts are installed inside the two bearing seats. The positioning sleeves are sleeved and installed on the outer surfaces of the two main shafts close to each other through stop bolts. The chain link orientation wheels are installed at one ends of the two main shafts close to each other.

[0020] Preferably, an upper chain plate is installed on the bottom wall of the lower frame by bolts. The top of the upper chain plate penetrates through the bottom of the lower frame and is provided with a slot hole for passing through the compensation chain.

[0021] Preferably, a foot adjustment module is installed at the bottom of the lower frame, and the foot adjustment module is used to adjust the overall height of the device. The foot adjustment module includes connecting plates embedded in the four corners of the bottom of the lower frame, an upper chain plate located between two sets of connecting plates, and an adjustment sleeve embedded in the center of the bottom of the four sets of connecting plates. The adjustment sleeve is internally threaded with a threaded rod, and the top end of the threaded rod extends through the bottom of the lower frame and into the interior of the lower frame. A support block is installed at the bottom end of the threaded rod to support the placement of the entire device.

[0022] Preferably, the method of using the tensioning and torque-reducing device is as follows:

[0023] S1. Before using the elevator balance compensation chain automatic chain tensioning and torque-reducing device, first rotate the support block two according to the usage needs, so as to drive the threaded rod to rotate in the adjusting sleeve, so as to adjust the distance between the support block two and the bottom of the lower frame, until the device is at a suitable height.

[0024] S2. Next, start the speed-regulating motor to drive the eccentric wheel to rotate, so that the adjusting screw can move with the rotation of the eccentric wheel, and then push the chain straightening plate to rotate on the centering shaft, so as to remove the torque of the compensation chain links and straighten the chain links.

[0025] S3. Then, pass through the top of the middle frame to enter the chain link guide clamping module, and adjust the ACE gas spring to drive the slider to move back and forth in the guide rail until the two sets of sliders can move closer or further apart, thereby completing the limiting and guiding of the compensation chain links.

[0026] S4. Next, the chain links of the compensation chain are introduced into the chain link tension adjustment module. Then, the number of counterweights on the connecting rod is increased or decreased according to the actual needs of use, thereby increasing or decreasing the downward pull of the boom. When the weight is increased, the boom will pull the limit plate down and move in the slot until the chain link tension of the compensation chain is in the optimal state. Finally, the chain links are exported through the chain link guide roller assembly at the top of the middle frame.

[0027] Preferably, step S1 further includes the following steps:

[0028] S11. Then, pass one end of the compensation chain through the slot in the upper chain plate, enter the slot 1 on the chain plate of the automatic chain placement and de-twisting module from below, and then pass through the lower frame to feed the compensation chain into the automatic chain placement and de-twisting module.

[0029] Step S3 further includes the following steps:

[0030] S31. After being guided by the chain link guide clamping module, the chain links are moved in the correct direction by two sets of chain link guide roller assemblies on the upper frame, so that the chain links can always be located inside the chain link guide rollers.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention, equipped with a speed-regulating motor, a base plate, an eccentric wheel, an adjusting screw, a centering shaft, a chain guide plate, and a slot, utilizes an automatic chain tensioning and torque-reducing device for the elevator's balancing compensation chain. First, the compensation chain is inserted from below the upper chain plate into the automatic chain link placement and torque-reducing module. After passing through slot one, it is guided into the chain link guide clamping module. During this process, the speed-regulating motor on the lower frame is activated, causing the eccentric wheel to rotate, which in turn moves the adjusting screw. Then, under the action of the adjusting screw, the chain guide plate rotates on the centering shaft, thereby removing the torque on the compensation chain links and straightening the chain links, improving their neatness.

[0033] 2. This invention, by installing guide rails, sliders, fixing blocks, and ACE gas springs, allows the ACE gas springs to adjust their extension and retraction accuracy according to the size of the chain link after it enters the chain link guide clamping module. This pushes the sliders to move within the guide rails, enabling the two sets of sliders to perform limit and guide operations on the chain link. This results in high safety and reliability, continuous production, high automation, and convenient operation.

[0034] 3. This invention, by installing a storage plate, a sliding guide block, a baffle, a slot, a hole, and a limiting plate, allows the elevator balance compensation chain automatic chain tensioning and torque-reducing device to first insert the limiting plate into the slot of the sliding guide block before use. The baffle is then fixed above the sliding guide block with bolts, allowing the baffle to limit the limiting plate. The chain guide roller assembly is then installed in the storage hole one on the limiting plate. In subsequent production processes, the tension is adjusted by the counterweight assembly, improving the flexibility of use.

[0035] 4. This invention, by installing a suspension rod, a support block, a storage hole, a connecting rod, and a counterweight, allows for adjustments to the chain tension by increasing or decreasing the number of counterweights on the connecting rod according to the chain specifications. This increases or decreases the downward pulling force of the suspension rod. When the counterweight is reduced, it pushes the limiting plate upward within the slot. When the counterweight is increased, the suspension rod increases the downward pulling force on the limiting plate, allowing the limiting plate to move downward within the slot. This, in turn, drives the chain guide roller assembly to move up and down, achieving the purpose of adjusting the sprocket tension. This improves the flexibility and convenience of using the elevator balance compensation chain automatic chain tensioning and torque-reducing device. Attached Figure Description

[0051] Please see Figure 1 , Figure 4 , Figure 8 and Figure 11This invention provides an embodiment of an automatic chain tensioning and torque-removing device for an elevator balance compensation chain, comprising a lower frame 1 and an automatic chain link placement and torque-removing module 2. The automatic chain link placement and torque-removing module 2 is used to remove the torque of the compensation chain links. The automatic chain link placement and torque-removing module 2 is assembled from a speed-regulating motor 12, a base plate 13, an eccentric wheel 14, an adjusting screw 15, a centering shaft 16, a chain guide plate 17, and a slot 18. The speed-regulating motor 12 is installed on the top wall of the lower frame 1. The base plate 13 is bolted to the top of the lower frame 1. The centering shaft 16 is fixed to the center of the top of the base plate 13 by connecting bolts. The output end of the speed-regulating motor 12 passes through the top of the base plate 13 and is fitted with an eccentric wheel 14. The chain guide plate 17 is mounted on the top of the centering shaft 16 via a shaft. To remove chain link torque and straighten the chain links, an adjusting screw 15 is installed on the top of the eccentric wheel 14 via a shaft. One end of the adjusting screw 15 is connected to the top of the chain guide plate 17 via a shaft. The top of the chain guide plate 17 has symmetrically arranged slots 18 for placing the compensation chain. The adjusting screw 15 is used to push the chain guide plate 17 to rotate on the centering shaft 16. The slots 18 have a "U" shape. The adjusting screw 15 is located in front of the centering shaft 16, and the eccentric wheel 14 is located on one side of the centering shaft 16. The shafts used to fix the chain guide plate 17 and the adjusting screw 15 are located in the middle of the two sets of slots 18. The bottom wall of the lower frame 1 is bolted to the upper chain plate 11. The top of the upper chain plate 11 has a slot through the bottom of the lower frame 1 for the compensation chain to pass through.

[0052] Furthermore, when using the elevator balance compensation chain automatic chain tensioning and torque-removing device, the compensation chain is first inserted into the chain link automatic placement and torque-removing module 2 from below the upper chain plate 11, and then guided into the chain link guide clamping module 3 after passing through the slot 18. During this process, the speed-regulating motor 12 on the lower frame 1 is started, driving the eccentric wheel 14 to rotate. At this time, the adjusting screw 15 can move in a circular motion with the rotation of the eccentric wheel 14. Then, under the action of the adjusting screw 15, the chain-aligning plate 17 can be pushed to rotate on the centering shaft 16, thereby achieving the purpose of removing the torque of the compensation chain links, straightening the chain links, improving the neatness of the chain links, effectively solving the gaps and torque between the compensation chain links, and eliminating the noise generated by the gaps between the compensation chain links and the shaking caused by the torque of the compensation chain.

[0053] Please see Figure 5 and Figure 6, an embodiment provided by the present invention: an automatic chain-up tensioning and torsion-removing device for an elevator balance compensation chain, including a chain link guiding and clamping module 3. A middle frame 8 is welded to the top of the lower frame 1, and an upper frame 9 is welded to the top of the middle frame 8. A bracket 10 arranged front and rear is welded to the outer wall of one side of the upper frame 9, and the bracket 10 is in an "L" shape. The bottom of the bracket 10 is connected to the top of the middle frame 8. A chain link guiding and clamping module 3 is installed on the top of the bracket 10, and the chain link guiding and clamping module 3 is used to clamp and guide the chain link. The chain link guiding and clamping module 3 is assembled into a complete set of device by a guide rail 19, a slider 20, a fixed block 21 and an ACE air spring 22. Symmetrically arranged guide rails 19 and fixed blocks 21 arranged front and rear are installed on the top of the two brackets 10 by bolts, and the surfaces of the two fixed blocks 21 close to each other are respectively connected to the front and back of the two guide rails 19. ACE air springs 22 are installed inside the two fixed blocks 21, and the output end of the ACE air spring 22 is installed with a slider 20, and the slider 20 is inside the guide rail 19. The ACE air spring 22 is used to adjust the moving distance of the slider 20 in the guide rail 19 according to different specifications of the chain link. There is a "mouth"-shaped gap in the middle after the two sliders 20 are combined together. The lower frame 1, the middle frame 8, the upper frame 9 and the bracket 10 are made of steel pipes or angle steels, and the lower frame 1, the middle frame 8, the upper frame 9 and the bracket 10 can bear the weight of all components and the operation requirements.

[0054] Further, when the compensation chain link enters the chain link guiding and clamping module 3 after passing through the chain link automatic placement and torsion-removing module 2, at this time, the telescopic precision of the ACE air spring 22 on the fixed block 21 is adjusted according to the size of the chain link, so as to push the slider 20 to move in the guide rail 19, so that the two sliders 20 can perform a limiting and guiding operation on the chain link, improving the convenience of subsequent guiding operations.

[0055] Please refer to Figure 2 , Figure 3 , Figure 7 and Figure 9This invention provides an embodiment of an automatic chain tensioning and torque-reducing device for an elevator balance compensation chain, comprising a chain tension adjustment module 4, a counterweight assembly 5, and a chain guide roller assembly 6. The chain tension adjustment module 4 is installed on the top of the lower frame 1 and is used to adjust the tension of the chain links. The chain tension adjustment module 4 is located to one side of the automatic chain placement and torque-reducing module 2 and is located below the side of the upper frame 9. The chain tension adjustment module 4 includes a shelf 23 bolted to the lower frame 1. Both shelves 23 have through holes 27 at their tops, and symmetrically arranged sliding guide blocks 24 are installed on the tops of both shelves 23. The through holes 27 are located in the middle of the two sets of sliding guide blocks 24. The surfaces of the two sets of sliding guide blocks 24 that are close to each other are provided with slots 26. A limiting plate 28 engages inside the slots 26. A baffle 25 is fixed to the top of each set of sliding guide blocks 24 by bolts, and the baffle 25 is located above the limiting plate 28 to limit its position. A storage hole 29 and a storage groove 30 are provided through the front of both sets of limiting plates 28, and the storage groove 30 is located below the storage hole 29. The limiting plate 28 has a "T"-shaped structure, and the bottom dimension of the limiting plate 28 is smaller than the size of the insertion hole 27. Under the action of gravity, the limiting plate 28 can slide downwards within the slots 26. The chain tension adjustment module 4 is located inside the middle frame 8. A counterweight component 5 is installed at the bottom of the chain tension adjustment module 4, and the counterweight component 5 is used for adjustment. The counterweight of the chain link tension adjustment module 4, the counterweight assembly 5 includes a lifting rod 31, a first support block 32, a second storage hole 33, a connecting rod 34, and a counterweight block 35. The lifting rod 31 is fixed inside the storage slot 30 by bolts, and one end of the lifting rod 31 extends from the bottom of the storage plate 23 through the inside of the insertion hole 27 to the inside of the lower frame 1. The bottom of both sets of lifting rods 31 is welded with a first support block 32. The surfaces of the two sets of first support blocks 32 that are close to each other are provided with second storage holes 33. The connecting rod 34 is fitted inside the two sets of second storage holes 33. The outer surface of the connecting rod 34 is fitted with evenly distributed counterweight blocks 35, and the counterweight blocks 35 are used to increase the downward pulling force of the downward lifting rod 31. The counterweight blocks 35 have an inverted "U" shape structure, which increases the force of the connecting rod 34. The number of counterweights 35 is sufficient to allow the boom 31 to pull the limiting plate 28 downwards within the slot 26. Chain guide roller assemblies 6 are installed on the top of the upper frame 9 and the middle frame 8, as well as inside the chain tension adjustment module 4. These assemblies ensure the correct running direction of the chain. Two sets of chain guide roller assemblies 6 are provided on the upper frame 9. Each chain guide roller assembly 6 consists of a bearing seat 36, a main shaft 37, a chain guide wheel 38, and a positioning sleeve 39. Bearing seats 36 are installed inside the two sets of storage holes 29, as well as on the top of the upper frame 9 and the middle frame 8. Main shafts 37 are installed inside both sets of bearing seats 36. Positioning sleeves 39 are installed on the outer surfaces of the two sets of main shafts 37 that are close to each other, connected by locking bolts.Two sets of main shafts 37 are fitted with chain guide wheels 38 at their ends, close to each other.

[0056] Furthermore, before using the automatic chain tensioning and torque-reducing device for the elevator balance compensation chain, firstly, the placement plate 23 is fixed to the top of the lower frame 1 with bolts. Then, the limiting plate 28 is inserted into the slot 26 on the sliding guide block 24, and the baffle 25 is fixed on the sliding guide block 24 so that it can limit the limiting plate 28. Next, as needed, one set of chain guide roller assemblies 6 is fixed in the placement hole 29. Then, one end of the compensation chain link after being clamped and guided by the chain guide clamping module 3 passes through the surface of the chain guide directional wheel 38 on the upper frame 9, then through the lower surface of the chain guide directional wheel 38 installed in the placement hole 29, and then through the upper surface of the chain guide directional wheel 38 in the final chain guide roller assembly 6 to export the compensation chain. The size of the ring can be increased or decreased by adding or removing the number of counterweights 35 on the connecting rod 34. When the number of counterweights 35 is increased, the lifting rod 31 can pull the limiting plate 28 downward, causing the limiting plate 28 to move within the slot 26. This, in turn, causes the chain guide roller assembly 6 at that position to move downward, thereby increasing the tension of the chain. Conversely, when the number of counterweights 35 is decreased, the connecting rod 34 can be manually pushed upward, allowing the lifting rod 31 to apply an upward thrust, causing the limiting plate 28 to move upward within the slot 26. This allows the counterweights 35 to tension the chain, causing the chain to run with tension during operation. This eliminates the gaps between the chain links and, to a certain extent, ensures the correct running direction of the chain, preventing unexpected shutdowns caused by inconsistent chain direction.

[0057] Please see Figure 10 An embodiment of the present invention provides an automatic chain tensioning and torque-reducing device for an elevator balance compensation chain, comprising a foot adjustment module 7. The foot adjustment module 7 is installed at the bottom of the lower frame 1 and is used to adjust the overall height of the device. The foot adjustment module 7 includes connecting plates 40 embedded in the four corners of the bottom of the lower frame 1. The chain plate 11 is located between two sets of connecting plates 40. An adjustment sleeve 41 is embedded in the center of the bottom of the four sets of connecting plates 40. A threaded rod 42 is threadedly connected to the inside of the adjustment sleeve 41. The top end of the threaded rod 42 extends through the bottom of the lower frame 1 and into the interior of the lower frame 1. A support block 43 is installed at the bottom end of the threaded rod 42 to support the placement of the entire device.

[0058] Furthermore, before using the elevator balance compensation chain automatic chain tensioning and torque-reducing device, first rotate the support block 43 according to the usage needs, which will drive the threaded rod 42 to rotate in the adjusting sleeve 41, so as to adjust the distance between the support block 43 and the bottom of the lower frame 1, so that the lower frame 1 is at a suitable height, thereby improving the practicality and functionality of the device to a certain extent.

[0059] Furthermore, the method of using this tensioning and torque-reducing device is as follows:

Before using the elevator balance compensation chain automatic chain tensioning and torque removal device, first rotate the support block 43 according to the usage needs, drive the threaded rod 42 to rotate in the adjusting sleeve 41, so as to adjust the distance between the support block 43 and the bottom of the lower frame 1, until the device is at a suitable height.

[0061] S2. Next, start the speed regulating motor 12 to drive the eccentric wheel 14 to rotate, so that the adjusting screw 15 can move with the rotation of the eccentric wheel 14, and then push the chain straightening plate 17 to rotate on the centering shaft 16 to remove the torque of the compensation chain links and straighten the chain links.

[0062] S3. Then, pass through the top of the middle frame 8 to enter the chain link guide clamping module 3, and adjust the ACE gas spring 22 to drive the slider 20 to move back and forth in the guide rail 19 until the two sets of sliders 20 can move closer or further away from each other, thereby completing the limiting and guiding of the compensation chain link.

[0063] S4. Next, the chain links of the compensation chain are introduced into the chain link tension adjustment module 4. Then, the number of counterweights 35 on the connecting rod 34 is increased or decreased according to the actual needs of use, thereby increasing or decreasing the downward pulling force of the lifting rod 31. When the weight is increased, the lifting rod 31 will pull down the limiting plate 28 to move in the slot 26 until the chain link tension of the compensation chain is in the optimal state. Finally, the chain links are exported through the chain link guide roller assembly 6 at the top of the middle frame 8.

[0064] Step S1 also includes the following steps:

[0065] S11. Then, one end of the compensation chain passes through the slot on the upper chain plate 11 and enters the slot 18 on the chain guide plate 17 of the automatic chain link placement and de-twisting module 2 from below. Then, it passes through the lower frame 1 to send the compensation chain into the automatic chain link placement and de-twisting module 2.

[0066] Step S3 also includes the following steps:

[0067] S31. After being guided by the chain link guide clamping module 3, the chain links are moved in the correct direction by the two sets of chain link guide roller assemblies 6 on the upper frame 9, so that the chain links can always be located inside the chain link directional wheel 38.

[0068] Working principle: Before using the automatic chain tensioning and torque-reducing device for the elevator balance compensation chain, first rotate the support block 43 according to the usage requirements, which will drive the threaded rod 42 to rotate in the adjusting sleeve 41. Adjust the distance between the support block 43 and the bottom of the lower frame 1 until the device is at a suitable height. Then, pass one end of the compensation chain through the slot on the upper chain plate 11 and enter the slot 18 on the chain guide plate 17 of the automatic chain link placement and torque-reducing module 2 from below. Then, pass through the lower frame 1 to send the compensation chain into the automatic chain link placement and torque-reducing module 2. Next, start the speed regulating motor 12 to drive the eccentric wheel 14 to rotate. Under the action of the adjusting screw 15, the chain guide plate 17 is pushed to rotate on the centering shaft 16 to achieve the purpose of removing the torque of the compensation chain links and straightening the chain links.

[0069] The compensation chain then passes through the top of the middle frame 8 into the chain link guide clamping module 3, and the ACE gas spring 22 is adjusted to drive the slider 20 to move back and forth within the guide rail 19 until the chain links of the compensation chain are limited and guided. Next, the chain links of the compensation chain are guided into the chain link tension adjustment module 4 through two sets of chain link guide roller assemblies 6 on the upper frame 9. Then, the number of counterweights 35 on the connecting rod 34 is increased or decreased according to actual needs, thereby increasing or decreasing the downward pull of the suspension rod 31 to achieve the purpose of tensioning the chain links, so that the chain links run with tension during operation, eliminating the gap between the chain links. Finally, the chain links are exported through the chain link guide roller assembly 6 at the top of the middle frame 8. This effectively solves the gap and torque between the chain links of the compensation chain, eliminates the noise of the compensation chain operation and the discomfort caused by the shaking of the compensation chain in the elevator, and the automatic chain loading of the compensation chain saves labor costs. It realizes the automatic chain loading and tensioning of single or multiple chain links to remove torque, effectively improves the production efficiency of the balance compensation chain and saves labor costs.
