A guide groove 34 is opened on the lifting plate 33 to cooperate with the guide shaft 35, and the guide shaft 35 slides in the corresponding guide groove 34.

[0015] By adopting the above technical solution, the five movable frames 32 can move at equal distances under the guidance of the guide rod 31.

[0016] Both slider 47 and slider 49 are equipped with pulley sets on the side near the bow-shaped clamp 41, and the pulley sets slide in the corresponding grooves on the bow-shaped clamp 41.

[0017] By adopting the above technical solution, the first slider 47 and the second slider 49 can slide stably on the bow-shaped clamp 41.

[0018] The two ends of the synchronizing rod 412 are slidably connected to the detection frame 2 via slide rails. A fixed frame 413 is fixedly installed in the middle of the synchronizing rod 412, and an electric cylinder 414 is fixedly installed in the middle of the detection frame 2. The driving end of the electric cylinder 414 is fixedly connected to the fixed frame 413.

[0019] By adopting the above technical solution, the electric cylinder 414 pushes the synchronizing rod 412 to move under the guidance of the slide rail through the fixed frame 413.

[0020] The detection frame 2 has a threaded rod 36 rotatably mounted in the middle, and a threaded ring 37 is threaded on the outer wall of the threaded rod 36 and fixedly installed in the middle of the lifting plate 33.

[0021] By adopting the above technical solution, the threaded rod 36 rotates and drives the lifting plate 33 to move up and down through the threaded ring 37.

[0027] By adopting the above technical solution, the drive rod 410 slides under the guidance of the guide block.

[0028] Working principle: Firstly, in practical applications, the spacing of the synchronous clamping assembly 4 is adjusted according to the distribution of the elevator wire rope spacing. Figure 1 , Figure 2 and Figure 5As shown, the drive end of the motor 38 is turned forward, which drives the threaded rod 36 in the detection frame 2 to rotate. The threaded ring 37 on the threaded rod 36 rotates with the thread, which drives the lifting plate 33 to move upward along the slide rail on the inner wall of the detection frame 2. The guide groove 34 on the lifting plate 33 cooperates with the guide shaft 35 on the moving frame 32. The five moving frames 32 slide at equal distances along the guide rod 31 to realize the synchronous adjustment of the spacing between the detection units 5. like Figure 3 As shown, the elevator wire rope is positioned between the limiting groove and the limiting block 43 of the clamping frame 42. Then, the electric cylinder 414 is controlled to retract, and the synchronous rod 412 is pushed to move horizontally along the slide rail of the detection frame 2 through the fixed frame 413. The synchronous rod 412 drives the guide ring 411 and the drive rod 410 to move, driving the second slider 49 to slide along the transverse slide groove of the bow-shaped clamping frame 41. The second slider 49 pulls the corresponding first slider 47 along the vertical slide groove of the bow-shaped clamping frame 41 through the two active rods 48, so that the two first sliders 47 move closer to each other. The first slider 47 drives the driven rod 46 and the push rod 45 to rotate together, so that the limiting block 43 rotates around the rotating shaft of the clamping frame 42, forcing the wire rope to fit tightly with the limiting groove and the limiting block 43 of the clamping frame 42, so as to realize the synchronous clamping of the wire rope by the clamping frame 42. Finally, the five detection units 5, along with the synchronous clamping assembly 4, after completing the clamping and spacing adaptation of the wire ropes, apply detection force to the wire ropes they clamp and collect tension data. Through the coordination of spacing adjustment and synchronous clamping, the force detection environment of multiple wire ropes is ensured to be consistent, and the load-sharing pre-tension detection of elevator wire rope tension is finally realized. After the detection is completed, the system can be reset according to the reverse steps above.
