Description

Technical Field

[0001] This utility model relates to the technical field of elevator compensation chain performance testing equipment, specifically an elevator compensation chain performance testing equipment. Background Technology

[0002] Currently, elevator compensating chains on the market consist of iron chains wrapped in PVC rubber composite materials. They are used to compensate for the weight of the steel wire ropes, ensuring smooth elevator operation. When the elevator is at the top floor, the steel wire ropes are on the counterweight side, adding weight to that side. When the elevator is at the bottom floor, the steel wire ropes are on the car side, adding weight to that side as well. The compensating chain balances this difference in height, acting as a dynamic balance. Because the steel wire ropes have weight, dynamic imbalances occur as the elevator moves up and down, hence the need for a compensating chain. Elevator compensating chain performance testing equipment is used to test the performance of these compensating chains.

[0003] Existing elevator compensation chain performance testing equipment involves a cumbersome process when installing the elevator compensation chain onto the testing device. Inaccurate positioning during installation leads to slow installation speed. After installation, during testing, the chain rotation can trigger a slippage phenomenon, causing the compensation chain to detach from the lower fixed seat and potentially resulting in an industrial accident. Therefore, an elevator compensation chain performance testing device is proposed to address these issues. Utility Model Content

[0023] An elevator compensation chain performance testing device includes a base 1, a fixing plate 5, a handwheel 8, a positioning rod 12, and a fixing hole 17. A lower fixing box 2 is fixedly connected to the top of the base 1. A threaded positioning block 15 is fixedly connected to the inner side of the lower fixing box 2. A threaded rod 11 is spirally connected to the inner side of the threaded positioning block 15. A bearing rod 10 is fixedly connected to the other end of the threaded rod 11. An elevator compensation chain 3 is in contact with the outer side of the bearing rod 10. An upper fixing device 7 is detachably connected to the top of the elevator compensation chain 3. A tensile testing device 6 is detachably connected to the top of the upper fixing device 7. The tensile testing device 6 is fixedly connected to the bottom of the fixing plate 5. An interactive panel 4 is provided on one side of the fixing plate 5.

[0024] A bearing rod 10 is fixedly connected to one side of the handwheel 8. A fixing block 9 is slidably connected to the outside of the bearing rod 10. A positioning rod 12 is fixedly connected to one side of the fixing block 9. A compensation chain through hole 13 is opened inside the top of the lower fixing box 2. An elevator compensation chain 3 is slidably connected inside the compensation chain through hole 13 to prevent the elevator compensation chain 3 from rotating during the experiment. A positioning block 14 is fixedly connected to the inside of the top of the lower fixing box 2. A positioning hole 16 is opened inside the positioning block 14. A fixing hole 17 is opened inside the positioning block 14. There are two positioning holes 16. A positioning rod 12 is slidably connected inside the positioning hole 16. A bearing rod 10 is slidably connected inside the fixing hole 17. The use of positioning holes 16 and positioning rods 12 can help the threaded rod 11 and the threaded positioning block 15 to be quickly positioned and connected.

[0025] Workflow: The power required for this utility model is provided by an external power source. First, the bottom end of the elevator compensation chain 3 is inserted into the lower fixed box 2 through the compensation chain through hole 13. Then, the bearing rod 10 and the positioning rod 12 are inserted into the lower fixed box 2 from one side, so that the threaded rod 11 and the bearing rod 10 pass through the fixing hole 17 opened inside the positioning block 14 in sequence. Then, the threaded rod 11 and the bearing rod 10 pass through the gap of the elevator compensation chain 3 in sequence until the threaded rod 11 is moved to one side of the threaded positioning block 15. At the same time, the positioning rod 12 fixed to one side of the fixing block 9 will slide into the fixed position. In the positioning hole 16 inside the positioning block 14, the handwheel 8 is rotated so that the threaded rod 11 fixed at one end of the bearing rod 10 forms a spiral connection with the threaded positioning block 15. Since the bearing rod 10 and the fixing block 9 are slidably connected, it will not affect the movement of the positioning rod 12. Then, the top end of the elevator compensation chain 3 is installed on the upper fixing device 7, and then the upper fixing device 7 is fitted onto the tension detection device 6 installed below the fixing plate 5. After the installation of the elevator compensation chain 3 is completed, the performance test of the elevator compensation chain 3 is performed by controlling the fixed tension detection device 6 through the interactive panel 4.
