[0033] Example 2 On the basis of Example 1, other configurations remain unchanged and the rope detection box 301 is partially replaced with the laser rangefinder 8 or the image recognition device, and the matching reflector plate 1 81 and reflector plate 2 82 are arranged on the elevator 200, so as to achieve the same measurement effect. However, these accessories have a higher initial arrangement cost than the example, and require professional personnel to perform maintenance in the later use and maintenance, which will incur labor costs and later costs. Compared with Example 1, no additional effect is produced, but the cost is increased.

[0034] Working principle of the present invention: When using the device, the lift 200 must first be docked inside the device and secured to prevent the lift 200 from tilting sideways during the inspection process, potentially causing safety accidents. The fixed hydraulic rod 401 is activated, and the output end of the fixed hydraulic rod 401 drives the positioning plate 402 to contact the lift 200. The positioning plates 402 on both sides of the device move closer to each other to secure the position of the lift 200. The movement of the positioning plates 402 is restricted by the sliding holes 403 and the sliding rods 404, and can only move within a fixed range. After the elevator 200 is fixed, it can be tested. The balance performance of the elevator 200 at different heights needs to be tested, and a test can be set every 0.5M. During the test, it is necessary to control the movement of the relevant components of the extrusion sleeve 700 on the elevator 200 through the adjustment mechanism. For example, in the rectangular load-bearing area of the elevator 200, the longitudinal movement is first carried out to detect the shaking amplitude of the elevator 200 under the longitudinal load change of the elevator 200, and then the lateral movement is carried out to detect the shaking amplitude of the elevator 200 under the lateral load change of the elevator 200. The hydraulic negative pressure rod 703 in the extrusion sleeve 700 can drive the load block 701 to squeeze the top of the elevator 200, thereby simulating different personnel loads. By using the universal movable wheel 702 to move at the top of the elevator 200, the impact of personnel activities on the elevator 200 can be simulated. Influence, start the horizontal movable drive motor 1 505, the output end of the horizontal movable drive motor 1 505 drives the basic movable block 501 to move through the horizontal movable drive screw rod 1 504, and the movable basic movable block 501 is restricted by the fixed slide rail 500 and can only move horizontally on the bottom side of the movable plate 102, then start the horizontal movable motor 2 509, the output end of the horizontal movable motor 2 509 drives the horizontal slider 507 to slide in the horizontal slide groove 506 through the horizontal movable screw rod 2 508, thereby driving the horizontal movable block 503 to move on the horizontal movable plate 502, and the movement of the horizontal movable plate 502 will also be restricted by the balance block 510 and the balance slide rail 511, further ensuring its stable movement. The components of this part cooperate with each other to realize the free movement of the extrusion sleeve 700 part in the horizontal direction, thereby ensuring a wide detection range; As for the detection part, the unwinding rope 305 is pulled out from the rope detection box 301 and connected to the connecting rope 302. The movement of the unwinding rope 305 is recorded by the electronic length counter 306, so that the swing amplitude data of the elevator 200 is recorded through the movement of the unwinding rope 305. The reset motor 303 drives the reset roller 304 to rotate, so as to achieve the reset of the unwinding rope 305 and ensure that the unwinding rope 305 is in a straight state. In order to facilitate the measurement, the position of the rope detection box 301 is adjusted by the mutual cooperation of the fixed sleeve 307 and the inner movable rod 308, and the telescopic motor 309 is used to drive the inner movable rod 308 to move in the fixed sleeve 307. The lifting mechanism is used to control the movable plate 102 to move on the fixed rod 101, so that the device can detect the elevator 200 at different heights, ensuring that the balance of the elevator 200 when used at different heights can be detected, so that designers can set the safe use range of the elevator 200 and limit loads at different heights. The drive motor 604 can be started, and the output end of the drive motor 604 drives the unwinding rope 305 to rotate, thereby releasing the lifting traction rope 601 wound on the rotating block 605, and using the electronic length counter 606 to record the moving distance of the lifting traction rope 601, to achieve precise control of the height of the movable plate 102 and ensure that the device can be detected at different heights.
