[0002] With the acceleration of urbanization, high-rise buildings are increasing day by day. As a key vertical transportation tool, the safety and stability of elevators are directly related to people's daily life and life safety. Elevator traction ropes, as the main load-bearing components in the elevator system, are usually made of high-strength steel wire ropes and need to withstand continuous tension and frequent lifting and lowering movements. Therefore, strength testing of the traction ropes before installation to ensure that they meet safety standards is an important part of ensuring the normal operation of the elevator.

[0003] Among the existing means of testing the strength of elevator traction ropes, tension testing is a commonly used method. By simulating the stress conditions of the traction rope in actual work, the tension test can intuitively reflect the load-bearing capacity and strength level of the traction rope. However, traditional tension testing devices often have shortcomings when fixing the traction rope, such as unstable fixation and easy sliding. These problems may not only affect the accuracy of the test, but also cause safety hazards to testers and equipment. Utility Model Content

A clamping mechanism 2 is fixed to the other side of the upper end surface of the base 1, and the clamping mechanism 2 is arranged corresponding to the clamping mechanism 1. The side wall of the base 1 is hinged to one end of a concave safety guard net 14, and a fixing buckle 15 is provided at the other end of the concave safety guard net 14. A slot used in conjunction with the fixing buckle 15 is opened on the upper end surface of the base 1, and the fixing buckle 15 is clamped in the slot.

[0026] The clamping mechanism 1 includes a fixing plate 3, a fixing block 4 and two clamping units 1;

[0027] The fixing plate 3 is fixedly connected to the tension sensor 2, the lower end of the fixing plate 3 is slidably connected to the base 1, the upper end of the fixing plate 3 is fixedly connected to the fixing block 4, the fixing block 4 is hinged to two clamping units, the two clamping units are both fixedly connected to the fixing plate 3, and the two clamping units are arranged correspondingly.

[0028] Each of the clamping units 1 includes a clamping plate 5, a fastening tooth 501, a slider 6 and a hydraulic cylinder 7;

[0029] The splint 5 is hinged to the fixed block 4, the inner wall of the splint 5 is provided with a fastening tooth 501, the outer wall of the splint 5 is provided with a slide groove 2 along the length direction, the slider 6 is slidably connected to the slide groove 2, the slider 6 is hinged to the telescopic end of the hydraulic cylinder 1 7, and the hydraulic cylinder 1 7 is fixedly connected to the fixed plate 3.

[0030] The clamping mechanism 2 includes a hydraulic cylinder 2 8, a concave plate 9, a fixing frame 10, a hydraulic cylinder 3 11, a slide plate 12, two clamping blocks 13 and two inclined plates 901;

[0031] The hydraulic cylinder 2 8 is horizontally fixed on the upper end surface of the base 1, the telescopic end of the hydraulic cylinder 2 8 is fixedly connected to the lower end surface of the concave plate 9, the side wall of the concave plate 9 is fixedly connected to the fixing frame 10, the fixing frame 10 is fixedly connected to the cylinder body of the hydraulic cylinder 3 11, the telescopic end of the hydraulic cylinder 3 11 is fixedly connected to one side of the slide plate 12, the two ends of the slide plate 12 are respectively slidably connected to the inner wall of the concave plate 9, the other side of the slide plate 12 is slidably connected to two clamping blocks 13, the two clamping blocks 13 are symmetrically arranged and the inner walls are provided with teeth, the outer walls of the two clamping blocks 13 are set as inclined surfaces, and the two inner walls of the concave plate 9 are provided with inclined plates 901 used in conjunction with the two clamping blocks 13.

[0032] When using the utility model, first, open the concave safety net 14 to ensure that the detection area is completely open, so as to facilitate the safe placement of the traction rope; then, start the two hydraulic cylinders 7, and through the movement of their telescopic ends, pull the splint 5 hinged thereto to open outward to provide sufficient space for the placement of the traction rope, carefully place one end of the traction rope to be detected between the two splints 5, and ensure that it is centered, then start the hydraulic cylinder 7 again, at this time the telescopic end of the hydraulic cylinder 7 will push the slider 6 to slide in the slide groove 2, and then push the splint 5 moves in the closing direction. Since the inner wall of the clamping plate 5 is provided with fastening teeth 501, these fastening teeth can effectively increase the friction between the traction rope and the traction rope, ensuring that the traction rope is firmly clamped between the clamping plates 5; then, the other end of the traction rope is placed between the two clamping blocks 13 of the clamping mechanism 2, and the hydraulic cylinder 3 11 is started.

The thrust of the slide plate 12 acts on the two clamping blocks 13. Since the outer wall of the clamping block 13 is designed as an inclined surface, it is in contact with the inner wall of the concave plate 9. The inclined plates 901 form a wedge-shaped fit, causing the clamping blocks 13 to move towards each other under the action of the inclined surface, thereby clamping the traction rope more firmly. The teeth on the inner wall of the clamping block 13 further enhance the clamping effect, ensuring that the traction rope will not slip during the detection process. After confirming that both ends of the traction rope are firmly clamped, close the concave safety net 14, and connect the fixed buckle 15 with the card slot to ensure that the safety protection measures during the detection process are in place; finally, start the hydraulic cylinder 2 8, and use the thrust of its telescopic end to push the entire clamping mechanism 2 Move in the direction away from the clamping mechanism 1, thereby applying tension to the traction rope. Under the action of the tension, the force borne by the traction rope is transmitted to the tension sensor 2 (the prior art) through the clamping mechanism 1. The tension sensor 2 will display the tension value in real time and continuously update the value as the tension increases. The inspection personnel can evaluate the strength performance of the traction rope by monitoring the value changes of the tension sensor 2 until the traction rope breaks. The entire inspection process is safe, efficient and accurate, and can provide reliable data support for the strength evaluation of the elevator traction rope.
