[0002] Generally, compensation chains are installed only on elevators with a height exceeding 30M. The compensation chain compensates for the weight of the steel wire rope, enabling the elevator to achieve a smooth running effect. During the use of the compensation chain, it is installed at the bottom of the elevator car. During the movement of the elevator car, the iron rings used for connection in the compensation chain are prone to collide with each other, resulting in damage to the compensation chain.

[0003] The defects existing in the existing elevator compensation chain devices are as follows:

[0019] Preferably, the working steps of the elevator compensation chain device with chain break protection are as follows:

[0020] S1. When the galvanized iron chain inside the transparent tube and the galvanized iron chain outside the transparent tube are in use and the main galvanized iron ring or the secondary galvanized iron ring is broken or fractured, affected by gravity, the galvanized iron chain below the fracture will move downward. Through one set of the multiple groups of first stainless steel ropes or the second stainless steel rope, the falling galvanized iron chain can be restricted and intercepted.

[0021] S2. During the restriction and interception process, the first tension monitoring module or the second tension monitoring module can detect abnormal tension data, and send the collected data to the judgment module and the processing center in real time to monitor and judge the fracture position, and contact the staff through the mobile data terminal for maintenance.

[0022] S3. Use tools to take out the access block from the notch. At this time, the damaged main galvanized iron ring or secondary galvanized iron ring can be removed, and a new main galvanized iron ring or secondary galvanized iron ring can be replaced.

[0023] S4. After the main galvanized iron ring or the secondary galvanized iron ring is replaced, the access block is inserted back into the notch again through the connection port, connection block and bolt. Push the limiting block to make the end of the limiting block disengage from the inner wall of the limiting ring. Rotate the limiting block to drive the bidirectional lead screw to rotate. Through the limiting block, the first rotating shaft, the connecting rod, the second rotating shaft and the push plate, the rotation of the bidirectional lead screw can drive the push plate to move, and the chute can limit the direction of the push plate. The push plate can reduce the collision when the main galvanized iron ring and the secondary galvanized iron ring move. Release the pushing tool, and the elastic force of the compression spring can push the end of the limiting block into the limiting ring, and the limiting ring can prevent the limiting block from rotating;

[0024] S5. The placement box and the pressure roller are provided to limit the galvanized iron chain and improve its stability during use. Through the base, the damper, the placement block and the transparent plate, the galvanized iron chain will hit the inner top wall of the monitoring room due to swinging and other situations during use. The damper can protect the placement block and the transparent plate.

[0025] Preferably, the following steps are further included in the step S1:

[0026] S11. According to the setting of multiple groups of first stainless steel ropes, the position of the first tension monitoring module that transmits abnormal data is determined through detection, and then the position where the main galvanized iron ring or the secondary galvanized iron ring is broken can be judged;

[0027] The following steps are further included in the step S2:

[0028] S21. The processing center can drive the PLC control module to control the camera and the lighting lamp, and can detect the connection condition of the main galvanized iron ring and the secondary galvanized iron ring entering the monitoring room in real time.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. Through the setting of the compensating chain, the safety rope, the first stainless steel rope and the first tension monitoring module of the present invention, the compensating chain installed in the transparent tube, when the main galvanized iron ring or the secondary galvanized iron ring is broken during use, affected by gravity, the compensating chain below the break will fall with gravity. During the falling process, the compensating chain will pull one of the multiple groups of first stainless steel ropes. The first stainless steel rope can intercept and limit the broken chain, and the first tension monitoring module can transmit the collected data, so as to achieve the effect of broken chain protection;

[0031] 2. The present invention uses one or the second set of stainless steel ropes from among the multiple sets of first stainless steel ropes to limit and intercept a falling compensating chain. During the interception process, the first tension monitoring module or the second tension monitoring module can detect abnormal tension data and send the collected data to the judgment module and processing center in real time to monitor and determine the break location. Repair personnel can then be contacted via a mobile data terminal for repair, thereby improving repair efficiency and user safety.

[0032] 3. The present invention is convenient for replacing the damaged main galvanized iron ring or the slave galvanized iron ring separately through the arrangement of the connecting port and the connecting block. The limiting block is pushed by a tool so that the tail end of the limiting block is separated from the inner wall of the limiting ring. The rotating limiting block can drive the cross hole and the cross rod to rotate, and then drive the bidirectional screw rod to rotate. Through the arrangement of the limiting block, the first rotating shaft, the connecting rod, the second rotating shaft and the push plate, the bidirectional screw rod can be rotated to adjust the movement of the push plate, and the slide groove can limit the moving direction of the push plate. The push plate can reduce the collision between the main galvanized iron ring and the slave galvanized iron ring during movement, thereby improving the safety of the main galvanized iron ring and the slave galvanized iron ring;

[0033] 4. The present invention limits the movement of the compensation chain through the arrangement of a placement box and a pressure roller, thereby improving its stability during movement. Through the arrangement of a base, a damper, a placement block and a transparent plate, the compensation chain will hit the inner top wall of the monitoring room due to swinging when moving, and the damper can protect the placement block and the transparent plate. Through the arrangement of a camera and a lighting lamp, the connection status of the main galvanized iron ring and the slave galvanized iron ring entering the monitoring room can be detected in real time, thereby improving safety in use.

[0062] Embodiment 6: Please refer to ​ , an embodiment provided by the present invention: The working steps of the elevator compensation chain device with chain break protection are as follows:

[0063] S1, the galvanized iron chain 12 inside the transparent tube 14 and the galvanized iron chain 12 outside the transparent tube 14, when the main galvanized iron ring 10 or the galvanized iron ring 11 is broken during use, the galvanized iron chain 12 below the break will move downward under the influence of gravity, and one of the multiple groups of first stainless steel ropes 16 or the second stainless steel rope 24 is respectively set to limit and intercept the falling galvanized iron chain 12;

[0064] S2. During the restricted interception process, the first tension monitoring module 7 or the second tension monitoring module 8 can detect abnormal tension data and send the collected data to the judgment module 2 and the processing center 3 in real time to monitor and determine the fracture location, and contact the staff for repair processing through the mobile data terminal 4;

[0065] S3. Use a tool to remove the access block 28 from the notch 25. Then, the damaged main galvanized iron ring 10 or the secondary galvanized iron ring 11 can be removed and replaced with a new main galvanized iron ring 10 or the secondary galvanized iron ring 11.

[0066] S4. After the main galvanized iron ring 10 or the slave galvanized iron ring 11 is replaced, the access block 28 is inserted back into the notch 25 through the connection port 26, the connection block 27 and the bolt, and the limiting block 31 is pushed so that the tail end of the limiting block 31 is separated from the inner wall of the limiting ring 30. The rotating limiting block 31 drives the bidirectional screw rod 39 to rotate. Through the setting of the limit block 41, the first rotating shaft 42, the connecting rod 43, the second rotating shaft 44 and the push plate 45, the rotation of the bidirectional screw rod 39 can drive the push plate 45 to move, and the slide groove 46 can limit the direction of the push plate 45. The push plate 45 reduces the collision between the main galvanized iron ring 10 and the slave galvanized iron ring 11 during movement, and the pushing tool is released. The elastic force of the pressure spring 35 can push the tail end of the limiting block 31 into the limiting ring 30, and the limiting ring 30 can prevent the limiting block 31 from rotating;

[0067] The arrangement of S5, the placement box 47, and the pressure roller 49 restricts the galvanized iron chain 12 and improves its stability during use. The arrangement of the base 50, the damper 53, the placement block 54, and the transparent plate 56 prevents the galvanized iron chain 12 from hitting the inner top wall of the monitoring chamber 52 due to swinging during use. The damper 53 protects the placement block 54 and the transparent plate 56.

[0068] Step S1 also includes the following steps:

[0069] S11. Based on the arrangement of the plurality of first stainless steel ropes 16, the position of the first tension monitoring module 7 transmitting abnormal data is determined by detection, thereby being able to determine the position where the main galvanized iron ring 10 or the secondary galvanized iron ring 11 is broken;

[0070] Step S2 also includes the following steps:

[0071] S21. The processing center 3 can drive the PLC control module 5 to control the camera 9 and the lighting lamp 55, and can detect the connection condition of the main galvanized iron ring 10 and the slave galvanized iron ring 11 entering the monitoring room 52 in real time.

[0072] Working principle: Through the settings of the galvanized iron chain 12, safety rope 15, first stainless steel rope 16, and first tension monitoring module 7, the galvanized iron chain 12 installed in the transparent tube 14, when the main galvanized iron ring 10 or the secondary galvanized iron ring 11 breaks during use, affected by gravity, the galvanized iron chain 12 below the break will move downward with gravity, driving the transparent soft rubber 13 to move downward together. The downward movement force of the galvanized iron chain 12 will pull one of the multiple groups of first stainless steel ropes 16. The first stainless steel rope 16 can limit and protect the broken chain. At the same time, when the first stainless steel rope 16 is subjected to tension, it will pull the first tension monitoring module 7. The first tension monitoring module 7 will send the collected data to the judgment module 2 and the processing center 3 in real time to monitor and judge the break position, and contact the staff through the mobile data terminal 4 for maintenance. Through the settings of the second tension monitoring module 8 and the second stainless steel rope 24, when the two ends of the galvanized iron chain 12 break, the falling galvanized iron chain 12 will be intercepted by the second stainless steel rope 24. At the same time, the force when the galvanized iron chain 12 falls can be transmitted to the second tension monitoring module 8 through the second stainless steel rope 24. The second tension monitoring module 8 will send the collected data to the judgment module 2 and the processing center 3 in real time, and contact the staff through the mobile data terminal 4 for maintenance. Through the settings of the connection port 26 and the connection block 27, it is beneficial to replace the damaged main galvanized iron ring 10 or secondary galvanized iron ring 11 separately, which is beneficial to saving resources and improving the maintenance efficiency after damage. By using a tool to push the limiting block 31, the end of the limiting block 31 is disengaged from the inner wall of the limiting ring 30. Then, through the settings of the cross hole 36 and the cross rod 37, rotating the limiting block 31 can drive the cross hole 36 and the cross rod 37 to rotate, and further drive the bidirectional lead screw 39 to rotate. Through the settings of the limiting block 41, the first rotating shaft 42, the connecting rod 43, the second rotating shaft 44, and the push plate 45, the rotation of the bidirectional lead screw 39 can adjust the movement of the push plate 45, and the chute 46 can limit the movement direction of the push plate 45. By the push plate 45, the collision during the movement of the main galvanized iron ring 10 and the secondary galvanized iron ring 11 is reduced, improving the use safety of the main galvanized iron ring 10 and the secondary galvanized iron ring 11. When the pushing tool is released, the elastic force of the compression spring 35 can push the end of the limiting block 31 into the limiting ring 30, and the limiting ring 30 can limit the rotation effect of the limiting block 31. Through the settings of the placement box 47 and the pressure roller 49, the movement of the galvanized iron chain 12 is restricted, improving its stability during movement. Through the settings of the base 50, the damper 53, the placement block 54, and the transparent plate 56, when the galvanized iron chain 12 moves, it will hit the inner top wall of the monitoring room 52 due to swinging or other situations. The damper 53 can protect the placement block 54 and the transparent plate 56. Through the settings of the camera 9 and the lighting lamp 55, the connection situation of the main galvanized iron ring 10 and the secondary galvanized iron ring 11 entering the monitoring room 52 can be detected in real time, thereby improving the use safety.
