Description

Technical Field

[0001] This invention relates to the field of elevator balance compensation chain technology, specifically to a highly stable elevator balance compensation chain and its usage method. Background Technology

[0002] Elevators are an essential mode of transportation in high-rise buildings. An elevator balance compensation chain is a device used in elevator shafts, usually installed inside the shaft, to balance the weight of the elevator and provide energy transmission. During elevator operation, the compensation chain is used to compensate for the weight of the steel wire rope. In vertical elevators, the compensation chain is an important device to ensure the stability and safety of elevator operation. The compensation chain consists of chains, rocker arms, and suspension rods.

[0003] The defects of existing elevator balance compensation chains are:

[0004] 1. Document KR2020090004473U discloses an elevator balance chain. "In constructing an elevator balance chain that is connected to the lower part of the elevator and the lower part of the counterweight respectively, balancing between the elevator and the attendant, at least two or more of the aforementioned balance chains are integrated into a single tube for insertion protection. The balance chain is flowably inserted into each insertion hole, but a weight and the balance chain are simultaneously inserted into each insertion hole. The weight is placed in a weight correction hole between the insertion holes of the balance chain and the tube, and the weight is placed inside the weight correction hole. Even when the elevator moves up and down, multiple balance chains will cause their respective balance chains to move left and right. While preventing upward flow, using a single balance chain does not significantly reduce or generate noise. Multiple balance chains connected to the elevator and the counterweight reduce concerns about short circuits. The bending alpha value of the balance chain connected to the lower part of the elevator and the lower part of the counterweight is smaller than that of conventional balance chains, providing an elevator balance chain that adapts to the elevator's movement." This elevator balance chain cannot adaptively adjust for wear generated during its own use. Continuous wear shortens the service life of the elevator balance chain and cannot guarantee the stability of the elevator during use.

[0005] 2. Document CN213864929U discloses a highly stable elevator balance compensation chain, "including a rubber sleeve, a galvanized layer, and a reinforcing chain. A second locking block is uniformly installed on one side of the rubber sleeve, and a locking structure is uniformly arranged on the other side of the rubber sleeve. A reinforcing chain is uniformly installed inside the rubber sleeve, and the reinforcing chain has a reinforcing structure inside. A first chain is wrapped around one side of the galvanized layer, and a second chain is wrapped around the other side of the galvanized layer. A second internal thread is provided on one side of the top and bottom ends of the first chain, and the second chain has a second internal thread on the top end of the second chain." Both the top and bottom sides are provided with a first internal thread. This utility model connects the rubber sleeve by installing a second locking block on one side of the rubber sleeve and engaging it between adjacent first locking blocks. The rubber sleeve is flexible, can be bent flexibly, is not easily worn, effectively reduces noise, and is easy to disassemble for maintenance. However, this elevator balance compensation chain cannot automatically detect the wear between the first and second chains, requiring manual inspection at irregular intervals, which cannot guarantee the safety performance of the elevator balance compensation chain during use.

[0006] 3. Document CN212050056U discloses a highly stable elevator balance compensation chain. "The locking ring has slots on both sides, and locking blocks are installed in these slots. The locking blocks are fixed to both sides of the locking ring with bolts, and the locking rings are connected to each other. Rollers are also installed at the connection points inside the locking rings. The connected locking rings are wrapped with a rubber composite layer. This utility model has a reasonable structure, and there is no torque between adjacent locking rings, avoiding deformation and rolling of the locking rings, thus ensuring the stability of the elevator. Unlike traditional compensation chains, there is no collision between adjacent locking rings, and no friction occurs on the inner side of the locking rings, thereby increasing the service life of the elevator balance compensation chain. Furthermore, the external rubber composite layer prevents two other locking rings connected to one from being located on the same side, thus ensuring that the overall length of the elevator balance compensation chain is always maximized, also guaranteeing the stability of the elevator." However, when this elevator balance compensation chain is inspected or replaced, the rubber composite layer needs to be completely removed, increasing the labor intensity of workers and the maintenance cost of the balance compensation chain.

[0007] 4. Document JP2015157663A discloses an elevator compensating chain / cable snap-fit ​​detection device. The problem to be solved is to provide a snap-fit ​​detection device that can detect the snap-fit ​​of the compensating chain / cable through a simple structure and prevent damage to the detection device during the detection process. The solution is an elevator compensating chain / cable snap-fit ​​detection device for detecting the snap-fit ​​of the compensating chain / cable between the car and the counterweight suspended in the hoistway, such that: two cantilevered support arms are fixed and arranged in the lower part of the hoistway; a movable rod is arranged upwardly movable between the free ends of the two supports; the compensating chain / cable suspended between the car and the counterweight is arranged to cross the movable rod; and a contact mechanism is included to actuate in conjunction with the upward movement of the movable rod. When the elevator compensating chain is worn out, the entire compensating chain needs to be replaced, which is inconvenient for operators and increases maintenance time, adversely affecting the use of the elevator. Summary of the Invention

[0008] The purpose of this invention is to provide a highly stable elevator balance compensation chain and its usage 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 highly stable elevator balance compensation chain, comprising an outer sheath, an alloy steel closed-loop chain, and an alloy steel contact chain.

[0012] Preferably, a lubrication component is provided on the outer side of the tension adjusting seat. The lubrication component is used to lubricate the chain tension adjusting component. The lubrication component includes an oil reservoir and a flow pipe. The oil reservoir is installed at the center of the outer side of the tension adjusting seat. A sealing cover is installed on the inner side of the oil reservoir. The flow pipe is opened on the inner wall of the oil reservoir and is connected to the sliding groove.

[0013] Preferably, the outer end of the outer sheath has a mating arc groove, the top of the other end of the outer sheath has an operating port that communicates with the mating arc groove, the outer end of the outer sheath has a snap-fit ​​protrusion, the outer end of the outer sheath has a snap-fit ​​groove at the end away from the snap-fit ​​protrusion that matches the snap-fit ​​protrusion, and the inner side of the outer sheath has a leak-proof filling putty.

[0014] Preferably, one end of the outer sheath is provided with a docking assembly, which is used to dock with the docking arc groove to assemble the outer sheath. The docking assembly includes a docking arc seat, a pressing plate, and an operating pressing column. The docking arc seat is installed on the outer sheath at the opposite end of the docking arc groove, and the docking arc seat is inserted into the inner side of the docking arc groove. A vertical pressing groove is opened on the top of the docking arc seat. The outer end of the pressing plate slides on the inner side of the vertical pressing groove. The operating pressing column is installed on the top of the pressing plate and cooperates with the operating port. A docking spring is installed on the bottom wall of the vertical pressing groove, and the top end of the docking spring is connected to the bottom of the pressing plate.

[0015] Preferably, an alloy steel connecting chain is installed on the outer side of the alloy steel contact chain, and the alloy steel connecting chain is sleeved with another alloy steel closed-loop chain. An assembly block is installed on the outer end of the alloy steel contact chain, and an assembly groove is opened on the outer end of the alloy steel connecting chain. The assembly block and the assembly groove cooperate with each other. Side grooves are symmetrically opened on the inner side of the outer sheath. A center side strip is installed on the front of the alloy steel contact chain, and the center side strip is engaged with the inner side of the side groove. A receiving groove is opened through the front of the center side strip. A threaded assembly hole one is opened on the front of the alloy steel contact chain, and a threaded assembly hole two is opened on the front of the alloy steel connecting chain. Assembly studs are installed on the inner sides of the alloy steel contact chain and the alloy steel connecting chain, and the assembly studs are threaded to the threaded assembly holes one and two. An assembly nut is installed on the inner side of the alloy steel connecting chain, and the assembly nut cooperates with the assembly stud.

[0016] Preferably, a wear monitoring component is provided on the inner side of the alloy steel connecting chain. The wear monitoring component is used to monitor the degree of wear between the alloy steel connecting chain and the alloy steel closed-loop chain. The wear monitoring component includes a detection slot, a friction contact sensor, and an illumination camera. The detection slot is opened on the inner side of the alloy steel connecting chain, and a friction contact sensor is installed on the inner side of the detection slot. The illumination camera is installed on the inner side of the outer sheath.

[0017] Preferably, the input end of the wear monitoring component is wirelessly connected to a control system. The control system includes a drive module, a receiving module, and an audible and visual alarm module. The drive module is used to control the elevator operation process according to the working state of the balance compensation chain. The receiving module is used to receive the output signals of the friction contact sensor and the lighting camera device. The output end of the receiving module is connected to an audible and visual alarm module, a friction comparison unit, and an image transmission unit. The audible and visual alarm module is used to warn the staff. The friction comparison unit is used to compare the value detected by the friction contact sensor with a preset friction value. The image transmission unit is used to transmit the image captured by the lighting camera device to the remote monitoring backend.

[0018] Preferably, the steps for using this elevator balance compensation chain are as follows:

[0019] S1. First, when the elevator balance compensation chain is working normally, it balances the weight of the elevator traction rope. The alloy steel contact chain pulls the alloy steel closed-loop chain to move continuously. During the movement of the alloy steel contact chain, its inner side contacts the pressure pad on the inner side of the top of the alloy steel closed-loop chain. The pressure pad reduces the sliding wear between the alloy steel contact chain and the alloy steel closed-loop chain. The pressure of the pressure pad causes the pressure seat to slide inside the sliding groove and squeeze the buffer spring. The buffer spring buffers the pressure and adaptively adjusts the tension between the alloy steel contact chain and the alloy steel closed-loop chain to prevent wear at the contact position caused by being too loose or too tight.

[0020] S2. When the elevator balance compensation chain is working, the friction contact sensor detects the friction between the inner bottom of the alloy steel connecting chain and the alloy steel closed-loop chain. The friction contact sensor transmits the detected data to the control system. When the friction value is higher than the preset value, it means that the chain thickness wear exceeds 10% of its original size. The lighting and camera device corresponding to the friction contact sensor at the abnormal wear location works to take pictures of the contact position between the alloy steel connecting chain and the alloy steel closed-loop chain and transmits them to the remote monitoring backend via the image transmission unit. The staff carefully observes the wear area. When the chain reaches the scrap level, the elevator stops running, and the staff replaces the damaged parts of the alloy steel connecting chain and the alloy steel closed-loop chain.

[0021] S3. When disassembling the outer sheath, press the operating pressure column through the operating port. The operating pressure column presses the pressure plate to move inside the vertical pressure groove and squeeze the docking spring. After releasing the limit of the operating pressure column by the operating port, pull one end of the outer sheath to disengage the docking arc seat from the docking arc groove and remove the outer sheath from the outside of the alloy steel closed-loop chain, alloy steel contact chain and alloy steel connecting chain.

[0022] S4. When replacing the damaged chain, fix the assembly nut and unscrew the assembly stud from the inner threads of threaded assembly hole one and threaded assembly hole two to release the thread lock on the alloy steel contact chain and alloy steel connecting chain. Pull the alloy steel contact chain to pull the assembly block out of the assembly slot. After the replacement is completed, assemble the alloy steel closed-loop chain, alloy steel contact chain and alloy steel connecting chain in sequence.

[0023] Preferably, step S1 further includes the following steps:

[0024] S11. During the pressure process of the clamping seat, the lubricating oil in the oil reservoir flows from the sliding groove to the tension regulating ring groove through the flow pipe and is absorbed by the clamping pad. The clamping pad lubricates the contact parts between the alloy steel contact chain and the alloy steel closed-loop chain to reduce friction and wear.

[0025] Step S3 further includes the following steps:

[0026] S31. After the worn chain is replaced, the outer sheath is placed on the outside of the alloy steel closed-loop chain, alloy steel contact chain and alloy steel connecting chain. The offset edge strip is engaged in the inside of the offset groove, and the center edge strip is engaged in the inside of the side groove. The operating pressure column is pressed so that it is located in the inside of the vertical pressure groove. After the docking arc seat is inserted into the inside of the docking arc groove, the docking spring pops upward due to its own elasticity, so that the outer end of the operating pressure column is engaged in the inside of the operating port to complete the assembly of the outer sheath.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. This invention features a chain tension adjustment component installed inside a miniature mounting groove. When the elevator balance compensation chain is working normally, the alloy steel contact chain pulls the alloy steel closed-loop chain to move continuously. During the movement of the alloy steel contact chain, its inner side contacts the wear-resistant pad on the inner side of the top of the alloy steel closed-loop chain. The pressure on the pad causes the pressure seat to slide inside the sliding groove, squeezing the buffer spring. The buffer spring buffers the pressure, adaptively adjusting the tension between the alloy steel contact chain and the alloy steel closed-loop chain. This prevents wear at the contact point due to excessive looseness or tightness, extending the service life of the elevator balance chain while enhancing the stability of the elevator during use.

[0029] 2. This invention incorporates a wear monitoring component on the inner side of the alloy steel connecting chain. During elevator balance compensation chain operation, a friction contact sensor detects the friction between the inner bottom end of the alloy steel connecting chain and the alloy steel closed-loop chain. When the friction value exceeds a preset value, it indicates severe wear on the chain links. The lighting and camera device corresponding to the friction contact sensor at the abnormal wear location captures images of the contact area between the alloy steel connecting chain and the alloy steel closed-loop chain. This automatic detection of the wear degree at the contact area between the alloy steel connecting chain and the alloy steel closed-loop chain ensures the safety performance of the elevator balance compensation chain during use.

[0030] 3. This invention features a docking assembly at one end of the outer sheath. When disassembling the outer sheath, the operating pressure column is pressed through the operating port. The operating pressure column presses the pressure plate, which moves inside the vertical pressure groove to compress the docking spring. After the operating port releases the limit on the operating pressure column, one end of the outer sheath is pulled to disengage the docking arc seat from the docking arc groove. The outer sheath is then removed from the outside of the alloy steel closed-loop chain, alloy steel contact chain, and alloy steel connecting chain. After the worn chain is replaced, the outer sheath is placed on the outside of the alloy steel closed-loop chain, alloy steel contact chain, and alloy steel connecting chain. The offset edge strip engages inside the offset groove, and the center edge strip engages inside the side groove. When the elevator balance compensation chain is inspected and replaced, the outer sheath at the damaged location is removed, reducing the labor intensity of the workers and lowering the maintenance cost of the balance compensation chain.

[0031] 4. This invention involves installing an alloy steel connecting chain on the outside of the alloy steel contact chain. When replacing a damaged chain, the assembly nut is fixed and the assembly stud is unscrewed from the inner threads of threaded assembly holes one and two, releasing the thread lock on the alloy steel contact chain and the alloy steel connecting chain. Pulling the alloy steel contact chain pulls the assembly block out of the assembly slot. After replacement, the alloy steel closed-loop chain, alloy steel contact chain, and alloy steel connecting chain are sequentially assembled. When the elevator compensation chain is worn out and scrapped, the damaged chain is replaced. This facilitates operation by staff, reduces maintenance time, and prevents excessive maintenance time from adversely affecting the use of the elevator. Attached Figure Description

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection or a movable connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] Please see Figure 1 , Figure 4 and Figure 5 The present invention provides an embodiment of a highly stable elevator balance compensation chain and its usage method;

[0047] The assembly includes an alloy steel closed-loop chain 2, a miniature mounting groove 16, and a tension adjusting seat 7. The miniature mounting groove 16 is located on the inner wall of one side of the alloy steel closed-loop chain 2. A chain tension adjusting component is located inside the miniature mounting groove 16. This component is used to adjust the tension transmitted between the alloy steel closed-loop chain 2 and the alloy steel contact chain 3. The chain tension adjusting component includes a tension adjusting seat 7, which is mounted on the inner wall of the miniature mounting groove 16. A tension adjusting ring groove 30 is located on the outer side of the tension adjusting seat 7. A retaining seat 32 is movably mounted inside the tension adjusting ring groove 30. A retaining pad 35 is mounted on the outer side of the retaining seat 32. A sliding groove 31 is located on the inner wall of the tension adjusting ring groove 30, and the outer end of the retaining seat 32 slides on the inner wall of the sliding groove 31. A damper 33 is mounted on the inner wall of the tension adjusting ring groove 30, and a buffer spring 34 is mounted on the outer side of the damper 33. The outer end of the buffer spring 34 is connected to the inner side of the retaining seat 32.

[0048] The miniature mounting slot 16 provides an installation position for the tension adjustment seat 7. The alloy steel contact chain 3 pulls the alloy steel closed-loop chain 2 to move continuously. During the movement, the inner side of the alloy steel contact chain 3 contacts the pressure pad 35 on the inner side of the top of the alloy steel closed-loop chain 2. The pressure pad 35 reduces the sliding wear between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2. The pressure pad 35 causes the pressure seat 32 to slide inside the sliding groove 31 and squeeze the buffer spring 34. The buffer spring 34 buffers the pressure. The damper 33 prevents the buffer spring 34 from driving the pressure seat 32 to shake back and forth. The tension between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 is adaptively adjusted to prevent wear at the contact position caused by excessive looseness or tightness.

[0049] Please see Figure 1 , Figure 4 and Figure 7 A highly stable elevator balance compensation chain and its usage method;

[0050] It includes a tension adjusting seat 7 and an oil reservoir 36. The tension adjusting seat 7 is installed on the inner wall of the miniature mounting groove 16. A lubrication component is provided on the outer side of the tension adjusting seat 7. The lubrication component is used to lubricate the chain tension adjusting component. The lubrication component includes an oil reservoir 36 and a flow pipe 38. The oil reservoir 36 is installed at the center of the outer side of the tension adjusting seat 7. A sealing cover 37 is installed on the inner side of the oil reservoir 36. The flow pipe 38 is opened on the inner wall of the oil reservoir 36 and is connected to the sliding groove 31.

[0051] The oil reservoir 36 stores lubricating oil, and the sealing cap 37 seals the oil reservoir 36. During the pressure process of the pressing seat 32, the lubricating oil in the oil reservoir 36 flows from the sliding groove 31 through the flow pipe 38 to the tension adjusting ring groove 30 and is absorbed by the pressing pad 35. The pressing pad 35 lubricates the contact parts of the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 to reduce friction and wear, which can effectively reduce chain wear during the use of the elevator compensation chain and improve the safety and stability of the elevator.

[0052] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 A highly stable elevator balance compensation chain and its usage method;

[0053] The assembly includes an alloy steel closed-loop chain 2, an alloy steel contact chain 3, and an alloy steel connecting chain 4. The alloy steel closed-loop chain 2 is installed inside the outer sheath 1, and the alloy steel contact chain 3 is also installed inside the outer sheath 1, with the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 interlocking. The alloy steel connecting chain 4 is installed outside the alloy steel contact chain 3, and the alloy steel connecting chain 4 and another alloy steel closed-loop chain 2 interlock. An assembly block 19 is installed at the outer end of the alloy steel contact chain 3, and an assembly groove 17 is formed at the outer end of the alloy steel connecting chain 4, with the assembly block 19 cooperating with the assembly groove 17. Symmetrical openings are formed on the inner side of the outer sheath 1.

The inner side of the alloy steel connecting chain 4 is equipped with mounting nuts 29, and the mounting nuts 29 cooperate with the mounting studs 28.

[0054] Alloy steel contact chain 3, alloy steel closed-loop chain 2, and alloy steel connecting chain 4 are all made of high-strength alloy steel, possessing excellent properties such as high strength, high hardness, high wear resistance, and high corrosion resistance. Alloy steel contact chain 3 and alloy steel closed-loop chain 2 are interlocked, and alloy steel connecting chain 4 is interlocked with another alloy steel closed-loop chain 2. When the elevator balance compensation chain is working normally, it balances the weight of the elevator traction rope. Alloy steel contact chain 3 pulls alloy steel closed-loop chain 2, causing it to move continuously. When replacing a damaged chain, the assembly nut 29 is fixed, and the assembly stud 28 is unscrewed from the inner threads of threaded assembly hole 18 and threaded assembly hole 22, releasing the thread lock on alloy steel contact chain 3 and alloy steel connecting chain 4. The alloy steel contact chain 3 is then pulled... Chain 3 pulls assembly block 19 out of assembly slot 17. After replacement, alloy steel closed-loop chain 2, alloy steel contact chain 3 and alloy steel connecting chain 4 are sequentially assembled. When the elevator compensation chain is worn and scrapped, the damaged chain is replaced separately. Assembly stud 28 penetrates the inside of the storage groove 27 to assemble alloy steel contact chain 3 and alloy steel connecting chain 4. After assembly, the operating end of assembly stud 28 is located inside the storage groove 27, which will not adversely affect the limiting connection between the outer sheath 1 and alloy steel contact chain 3 and alloy steel connecting chain 4. One end is inserted into the limiting position and the other end is limited by assembly stud 28. While ensuring the stability of the connection, it is convenient to quickly replace alloy steel contact chain 3 or alloy steel connecting chain 4 when it is damaged.

The operating pressing column 26 is installed on the top of the pressing plate 24, and the operating pressing column 26 cooperates with the operating port 11. A docking spring 25 is installed on the bottom wall of the vertical pressing groove 23, and the top end of the docking spring 25 is connected to the bottom of the pressing plate 24.

[0058] The offset strip 15 engages with the inside of the offset groove 9 to limit the outer sheath 1 to the alloy steel closed-loop chain 2. The center strip 6 engages with the inside of the side groove 8 to limit the outer sheath 1 to the alloy steel contact chain 3. When the outer sheath 1 is disassembled, the operating pressure column 26 is pressed through the operating port 11. The operating pressure column 26 presses the pressure plate 24 to move inside the vertical pressure groove 23 and squeeze the docking spring 25. After the operating port 11 releases the limit on the operating pressure column 26, one end of the outer sheath 1 is pulled to disengage the docking arc seat 5 from the docking arc groove 10. The outer sheath 1 is then removed from the outside of the alloy steel closed-loop chain 2, the alloy steel contact chain 3 and the alloy steel connecting chain 4. When the elevator balance compensation chain is repaired and replaced, the outer sheath 1 at the damaged position is removed.

[0059] After the worn chain is replaced, the outer sheath 1 is placed on the outside of the alloy steel closed-loop chain 2, the alloy steel contact chain 3, and the alloy steel connecting chain 4. The offset edge strip 15 is engaged with the inside of the offset groove 9, and the center edge strip 6 is engaged with the inside of the side groove 8. The operating pressure column 26 is pressed so that it is located inside the vertical pressure groove 23. After the docking arc seat 5 is inserted into the inside of the docking arc groove 10, the docking spring 25 pops upward due to its own elasticity, so that the outer end of the operating pressure column 26 is engaged with the inside of the operating port 11, thus assembling the outer sheath 1.

[0060] Please see Figure 2 , Figure 7 , Figure 9 and Figure 10 A highly stable elevator balance compensation chain and its usage method;

[0061] The system includes a friction contact sensor 21, an illumination camera device 14, and a control system. A wear monitoring component is installed on the inner side of the alloy steel connecting chain 4. The wear monitoring component is used to monitor the wear degree between the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2. The wear monitoring component includes a detection slot 20, a friction contact sensor 21, and an illumination camera device 14. The detection slot 20 is opened on the inner side of the alloy steel connecting chain 4. The friction contact sensor 21 is installed on the inner side of the detection slot 20. The illumination camera device 14 is installed on the inner side of the outer sheath 1. The input end of the wear monitoring component is wirelessly connected to the control system. The control system includes a drive module, a receiving module, and an audible and visual alarm module. The output end of the receiving module is connected to an audible and visual alarm module, a friction comparison unit, and an image transmission unit.

[0062] The detection slot 20 provides an installation position for the friction contact sensor 21. When the elevator balance compensation chain is working, the friction contact sensor 21 detects the friction between the inner side of the bottom end of the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2. As the thickness of the alloy steel closed-loop chain 2 wears, the friction between the two will continuously increase. The friction contact sensor 21 transmits the detection data to the control system. When the friction value is higher than the preset value, it means that the thickness of the chain piece wears more than 10% of its original size. The lighting and camera device 14 corresponding to the friction contact sensor 21 at the abnormal wear position works to take pictures of the contact position between the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2 and transmits them to the remote monitoring backend through the image transmission unit. The lighting and camera device 14 has its own lighting function and is adapted to the dark environment inside the outer sheath 1. The staff carefully observes the wear area. When the chain reaches the scrap level, the elevator stops running, and the staff replaces the damaged parts of the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2.

[0063] The drive module is used to control the elevator operation process according to the working status of the balance compensation chain. The receiving module is used to receive the output signals of the friction contact sensor 21 and the lighting camera device 14. The sound and light alarm module is used to warn the staff. The friction comparison unit is used to compare the value detected by the friction contact sensor 21 with the preset friction value. The image transmission unit is used to transmit the image captured by the lighting camera device 14 to the remote monitoring backend.

[0064] The steps for using this elevator balance compensation chain are as follows:

[0065] S1. First, when the elevator balance compensation chain is working normally, it balances the weight of the elevator traction rope. The alloy steel contact chain 3 pulls the alloy steel closed-loop chain 2 to move continuously. During the movement of the alloy steel contact chain 3, its inner side contacts the wear-resistant pad 35 on the inner side of the top of the alloy steel closed-loop chain 2. The pad 35 reduces the sliding wear between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2. The pad 35 is pressed, causing the pressing seat 32 to slide inside the sliding groove 31 and squeeze the buffer spring 34. The buffer spring 34 buffers the pressing pressure and adaptively adjusts the tension between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 to prevent wear at the contact position due to excessive looseness or tightness.

[0066] S2. When the elevator balance compensation chain is working, the friction contact sensor 21 detects the friction between the inner bottom of the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2. The friction contact sensor 21 transmits the detected data to the control system. When the friction value is higher than the preset value, it means that the thickness of the chain piece is worn by more than 10% of its original size. The lighting and camera device 14 corresponding to the friction contact sensor 21 at the abnormal wear position works to take pictures of the contact position between the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2 and transmits them to the remote monitoring backend through the image transmission unit. The staff carefully observes the wear area. When the chain reaches the scrap level, the elevator stops running. The staff replaces the damaged parts of the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2.

[0067] S3. When disassembling the outer sheath 1, the operating pressure column 26 is pressed through the operating port 11. The operating pressure column 26 presses the pressure plate 24 to move inside the vertical pressure groove 23 and squeeze the docking spring 25. After the operating port 11 releases the limit on the operating pressure column 26, one end of the outer sheath 1 is pulled to separate the docking arc seat 5 from the docking arc groove 10. The outer sheath 1 is then removed from the outside of the alloy steel closed-loop chain 2, the alloy steel contact chain 3 and the alloy steel connecting chain 4.

[0068] S4. When replacing the damaged chain, fix the assembly nut 29 and unscrew the assembly stud 28 from the inside of the threaded assembly hole 18 and the threaded assembly hole 22 to release the thread lock on the alloy steel contact chain 3 and the alloy steel connecting chain 4. Pull the alloy steel contact chain 3 to pull the assembly block 19 out of the assembly groove 17. After the replacement is completed, assemble the alloy steel closed-loop chain 2, the alloy steel contact chain 3 and the alloy steel connecting chain 4 in sequence.

[0069] Step S1 also includes the following steps:

[0070] S11. During the pressure process of the clamping seat 32, the lubricating oil in the oil reservoir 36 flows from the sliding groove 31 to the tension regulating ring groove 30 through the flow pipe 38 and is absorbed by the clamping soft pad 35. The clamping soft pad 35 lubricates the contact part between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 to reduce friction and wear.

[0071] Step S3 also includes the following steps:

[0072] S31. After the worn chain is replaced, the outer sheath 1 is placed on the outside of the alloy steel closed-loop chain 2, the alloy steel contact chain 3 and the alloy steel connecting chain 4. The offset edge strip 15 is engaged in the inside of the offset groove 9, and the center edge strip 6 is engaged in the inside of the side groove 8. The operating pressure column 26 is pressed so that it is located inside the vertical pressure groove 23. After the docking arc seat 5 is inserted into the inside of the docking arc groove 10, the docking spring 25 pops upward due to its own elasticity, so that the outer end of the operating pressure column 26 is engaged in the inside of the operating port 11 to realize the assembly of the outer sheath 1.

[0073] Working principle: When using this device, the elevator balance compensation chain first balances the weight of the elevator traction rope during normal operation. The alloy steel contact chain 3 pulls the alloy steel closed-loop chain 2 to move continuously. During the movement of the alloy steel contact chain 3, its inner side contacts the wear-resistant pad 35 on the inner side of the top of the alloy steel closed-loop chain 2. The pad 35 reduces the sliding wear between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2. The pressure on the pad 35 causes the abutment seat 32 to slide inside the sliding groove 31, which in turn affects the buffer spring 3. 4. The compression is applied, and the buffer spring 34 buffers the pressing pressure and adaptively adjusts the tension between the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 to prevent wear at the contact position due to excessive looseness or tightness. During the compression process, the lubricating oil in the oil reservoir 36 flows from the sliding groove 31 to the tension adjustment ring groove 30 through the flow pipe 38 and is absorbed by the pressing soft pad 35. The pressing soft pad 35 lubricates the contact part of the alloy steel contact chain 3 and the alloy steel closed-loop chain 2 to reduce friction and wear.

[0074] When the elevator balance compensation chain is working, the friction contact sensor 21 detects the friction between the inner bottom of the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2. The friction contact sensor 21 transmits the detected data to the control system. When the friction value is higher than the preset value, it means that the thickness of the chain piece is worn by more than 10% of its original size. The lighting and camera device 14 corresponding to the friction contact sensor 21 at the abnormal wear location works to take pictures of the contact position between the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2 and transmits them to the remote monitoring backend via the image transmission unit. The staff carefully observes the wear area. When the chain reaches the scrap level, the elevator stops running, and the staff replaces the damaged parts of the alloy steel connecting chain 4 and the alloy steel closed-loop chain 2.

[0075] When disassembling the outer sheath 1, the operating pressure column 26 is pressed through the operating port 11. The operating pressure column 26 presses the pressure plate 24 to move inside the vertical pressure groove 23 and squeeze the docking spring 25. After the operating port 11 releases the limit on the operating pressure column 26, one end of the outer sheath 1 is pulled to separate the docking arc seat 5 from the docking arc groove 10. The outer sheath 1 is removed from the outside of the alloy steel closed-loop chain 2, alloy steel contact chain 3 and alloy steel connecting chain 4. When replacing the damaged chain, the assembly nut 29 is fixed and the assembly stud 28 is unscrewed from the inside of the threaded assembly hole 18 and the threaded assembly hole 22. The threaded locking of the alloy steel contact chain 3 and alloy steel connecting chain 4 is released. The assembly block 19 is pulled out from the assembly groove 17 by pulling the alloy steel contact chain 3. After the replacement is completed, the alloy steel closed-loop chain 2, alloy steel contact chain 3 and alloy steel connecting chain 4 are assembled in sequence.

[0076] After the worn chain is replaced, the outer sheath 1 is placed on the outside of the alloy steel closed-loop chain 2, the alloy steel contact chain 3, and the alloy steel connecting chain 4. The offset edge strip 15 is engaged with the inside of the offset groove 9, and the center edge strip 6 is engaged with the inside of the side groove 8. The operating pressure column 26 is pressed so that it is located inside the vertical pressure groove 23. After the docking arc seat 5 is inserted into the inside of the docking arc groove 10, the docking spring 25 pops upward due to its own elasticity, so that the outer end of the operating pressure column 26 is engaged with the inside of the operating port 11, thus assembling the outer sheath 1.
