[0002] As a crucial component of elevators, the quality of steel wire ropes directly affects the elevator's operational quality and lifespan, and is also closely related to people's safety. Strength testing is required before steel wire ropes are put into use to ensure safety during operation.

[0003] The current announcement number is CN221587736U, which describes a testing device for elevator wire ropes. The device includes a testing platform, a protective support mechanism on the testing platform, and a drive testing mechanism. The protective support mechanism includes a protective cabinet and a cabinet door. The protective cabinet is located on the testing platform, and the cabinet door is located on the protective cabinet. The drive testing mechanism includes a movable frame and a hydraulic cylinder. The movable frame and the hydraulic cylinder are located on the side wall of the protective cabinet. The output end of the hydraulic cylinder is equipped with a pressure sensor. A connecting frame is connected to the pressure sensor. A limit component is connected to the bottom wall of the connecting frame, and rollers are rotatably mounted on the connecting frame. This utility model belongs to the field of elevator testing technology, specifically referring to a testing device with a protective structure that is accurate and convenient for testing elevator wire ropes. In the actual use of this device, the fixing of both ends of the wire rope is done manually, which is not convenient for quickly fixing both ends of the wire rope, greatly prolonging the testing time of the wire rope and making it inconvenient to use. At the same time, it is not convenient to perform multiple segment tests on the same wire rope, requiring repeated manual operation and testing, which reduces the efficiency of the testing device. Therefore, we have proposed a testing device that is convenient for testing elevator wire ropes. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This testing device for elevator wire ropes facilitates the testing of both ends of the wire rope. The wire rope passes sequentially through a first square sleeve, a pull sleeve, and a second square sleeve. A second motor drives a first lead screw to rotate, causing a first push plate to push a first push rod downwards. This causes a first clamping block and a first pad to clamp and fix the inlet end of the wire rope. A third motor then drives a second lead screw to rotate, causing a second push plate to push a second push rod upwards. This causes a second clamping block and a second pad to fix the outlet end of the wire rope. This allows for quick and easy fixing of both ends of the wire rope, reducing testing time and simplifying its use.

[0018] 2. This inspection device for elevator wire ropes facilitates the inspection of elevator wire ropes by passing the wire rope sequentially through a first square sleeve, a pull sleeve, and a second square sleeve. The end of the wire rope passing through the second square sleeve is then inserted into a clamping block. Next, a first motor drives a roller to rotate, causing the wire rope to wind up. Then, the inlet end of the wire rope is clamped and fixed by a first clamping block and a first pad, and the outlet end of the wire rope is fixed by a second clamping block and a second pad. This allows for easy inspection of different sections of the same wire rope, facilitating multiple section inspections of the same wire rope without the need for repeated manual inspections, thus improving the efficiency of the inspection device.

The second clamping block 380, in conjunction with the second pad 310, fixes the exit end of the wire rope. Then, the electric hydraulic rod 120 is activated to retract, causing the electric hydraulic rod 120 to work with the pull sleeve 140 and pressure sensor 150 to detect the wire rope. After the detection is completed, the second motor 240 and the third motor 340 are activated to release the wire rope, and the first motor 170 is activated simultaneously. The first motor 170 drives the roller 180 to rotate and wind up the wire rope to adjust the detection section of the wire rope.
