The limiting block 506 can limit the limiting steel wire rope 507 so that the limiting steel wire rope 507 located at the lower end of the limiting block 506 remains vertical. At the same time, the reinforcing steel plate can reduce the wear of the hole of the limiting block 506 caused by the limiting steel wire rope 507 when it is raised or lowered.

[0044] The implementation principle of the embodiment of the dynamic monitoring device for foundation pit slope stability of the present invention is as follows:

[0045] When the staff needs to adjust the height of the monitoring device 512, the staff starts the motor 503 to drive the rotating rod 504 to rotate. Through the rotation of the rotating rod 504, the limiting wire rope 507 is wound. While winding, the winding position can be limited by the fixed disk 505 to reduce the space when winding. When the limiting wire rope 507 is wound, the limiting wire rope 507 located at the upper end of the limiting block 506 has a large inclination, which causes wear to the limiting block 506. When the limiting wire rope 507 moves up and down, it can drive the lifting plate 509 to move up and down. When the lifting plate 509 moves up and down, the fixed plate on the left side of the lifting plate 509 The sliding of the slider 510 and the vertical slide groove 7, as well as the connecting rod 604 fixed on both sides of the cross bar 511 fixed to the right side of the lifting plate 509 and the sliding of the limiting slider 603 and the slide rod 601 can assist in limiting the right side of the lifting plate 509; at the same time, when the base plate 1 is fixed, the reinforcing support auxiliary mechanism 4 on the left side of the support column 2 can assist in fixing the support column 2. After fixing the fixed plate 403, the limiting wire rope 402 is adjusted in length to pull the left side of the support column 2 by the limiting wire rope 402; through the cooperation of the above structures, the problem of the threaded rod being damaged and being unable to drive the monitoring equipment 512 to be lifted or lowered is solved.
