[0010] Through the above technical solution, after the plug-in limit block is moved under the sliding seat, the electric push rod drives the push block to lift up, and externally presses the four extension pads outside the plug-in limit block.
[0011] Furthermore, one end of the spring facing away from the push block is fixedly connected to the inner side wall of the cross deep groove.
[0012] Through the above technical solution, after the push block is lowered to the original position, the outward ends of the four extension pads can be retracted, which facilitates the insertion block to be pulled out of the sliding seat and the sliding seat to be removed from the outside of the vertical frame.

[0014] Through the above technical solution, the rope winding roller can rotate to lower the wire rope and the limit block, and then the rope winding roller can reverse to lift the limit block, thereby realizing rapid adjustment of the vertical frame outer sliding mount and the crossbeam height.
[0015] Furthermore, a servo motor is installed on the side of the stabilization platform, and the output end of the servo motor is fixedly connected to the end of the rotating shaft opposite to it through a coupling.
[0016] Through the above technical solution, the servo motor drives the rope winding roller in forward and reverse directions.

[0033] The plug-in limit component includes a plug-in limit block 10 and a top block 11 fixed on the top of the plug-in limit block 10. A cross deep groove is opened on the top of the plug-in limit block 10. Sliding openings 1001 are opened on the four sides of the plug-in limit block 10. Extension pads 12 are inserted and slidably connected in the four sliding openings 1001, and two springs 16 are symmetrically installed on one end of each extension pad 12 extending into the cross deep groove. A pressure-feeding component matching the four extension pads 12 is provided at the lower part of the plug-in limit block 10; the pressure-feeding component includes a push block 15 movably inserted in the cross deep groove, and the inclined surfaces on the four sides of the push block 15 are respectively arranged to be in a fit with the inner extending inclined surfaces of the four extension pads 12. A suspension 13 is fixedly installed on the bottom side of the plug-in limit block 10, and an electric push rod 14 is installed on the inner bottom side of the suspension 13.
