Folding type lifting device for tunnel vertical arch frame

The invention belongs to the field of folding lifting, and particularly relates to a folding lifting device for a tunnel vertical arch frame, which comprises a chassis, four guide wheels are connected to the bottom of the chassis, lock catches are arranged on the outer sides of the four guide wheels, a folding frame is connected to the top of the chassis, and two hydraulic rods are connected to the top of the chassis. The top of the hydraulic rod is rotationally connected with the outer edge of the folding frame, and a plurality of buffer balls are placed in the protection frame, so that an operator strides into the protection frame, the shank part can be semi-covered, the shank and the instep of the operator are restrained, and even if the operator falls down, the operator only falls over the plurality of buffer balls, so that the safety of the operator is ensured. Compared with the prior art, the device has the advantages that the buffer ball is arranged on the tunnel, large impact damage cannot be generate
