（1）Front rod, back link and caving shield are assembled in advance, caving shield assembly is formed, caving shield is placed on carrying On roof beam structure, front rod is freely placed, and back link is placed on the first passage roof beam structure and the second passage roof beam structure；Top beam is placed on water On flat-pushing moving device, pedestal is placed on scooter；

（2）Moving slide board vehicle keeps the sweep of scooter parallel with the bottom plate of caving shield assembly thrust gear, then fixes very heavy Under roof fall, scooter is carried out to stablize support；

（3）First lifting jack and the action of the second lifting jack drive the first passage roof beam structure, the second passage roof beam structure and carrying Roof beam structure acts, and the action of third lifting jack drives third passage roof beam structure action, by the mounting hole of front rod and back link bottom end Centering is carried out with the mounting hole on pedestal, axis pin is then charged into, caving shield assembly is made to be assembled with pedestal；

Lifting gear and horizontal translocation device start operation, and top beam movement is made to the mounting hole pair of top beam and caving shield front end in place In, it is then charged into axis pin, so that top beam and caving shield assembly is assembled, is finally completed the assembling of entire hydraulic support.
