Based on the above, the mobile trolley is provided with a pumping station system and a hydraulic motor, the bottom of the mobile trolley is provided with a driving wheel and a driven wheel, the hydraulic motor drives the driving wheel to rotate, and the pumping station system is the hydraulic motor. The motor, the four lifting cylinders, the swing cylinder, the lateral movement cylinder and the clamping cylinder provide power fluid.

Compared with the prior art, the utility model has substantive characteristics and progress, specifically, the utility model has the following advantages:

(1) Through the lifting of the lifting platform, the clamping platform can be close to or away from the roof of the roadway, and the beam of the portal bracket can be clamped by the claws of the bracket beam on the clamping platform, and rotated by the rotary platform Make the portal bracket tilt at a certain angle so as to pass through the bottom of the front portal bracket, move to the front end of the transfer machine, reset through the slewing platform, make the portal bracket straight, and pass through the lateral side of the clamping platform Moving can adjust the position of the portal bracket in the roadway section, and finally lift up the portal bracket through the lifting of the lifting platform. After the support is completed, the jaws of the bracket beam can be released.

(2) The four lifting cylinders are symmetrically distributed in pairs on both sides of the transfer machine, which can balance the force on both sides and improve the stability of the lifting platform.

(3) The pump station system is integrated on the mobile trolley to provide a power source for various actions of the handling device, all of which use internal transmission to make the rotating mechanism simpler.
