The arch frame of the equipment is installed as follows: when the middle arch is hung, the arch placed on the ground is hung by using the ropes in the working platform winch 54 on the middle fixed platform 51, the arch is flexibly lifted in a tilting mode, the middle position of the arch is grabbed by the middle manipulator 63 in the upward lifting process, the ropes are released, the arch 180 is turned over, and the arch is placed on the arch installation place in a roadway by moving the arm support assembly 4. When the left arch frame is flexibly picked up, two hanging points are arranged. The winch puts down the rope, the left winch 618 on the left manipulator 61 hangs the front end of the arch, and the winch 54 of the same side middle fixed platform 51 hangs the rear end of the arch, and the hoisting machine hangs from the ground. During the lifting process, the left winch 618 on the left manipulator 61 slowly takes up the rope, and the winch 54 of the middle fixed platform 51 slowly releases the rope, so that a stable balance state is maintained, and the arch centering is prevented from shaking. In the process of lifting, the rope outlet end of the left guide rope wheel 6111 is arranged between the two limiting frames 6113, and the arch frame finally falls into the limiting frame on the manipulator to realize positioning. And similarly, the process of the right arch frame is consistent with the flexible picking and hoisting process of the left arch frame. The worker performs a connection operation on the connection of the three arches on the left telescopic platform 52 and the right telescopic platform 53, and completes the arch erecting process.
