Tunnel anchor rod trolley lifting device

The utility model relates to the technical field of tunnel engineering, in particular to a tunnel anchor rod trolley lifting device which comprises a base, a fixing mechanism is arranged on the base, and the fixing mechanism comprises a fixing plate, a first rotating disc, a second rotating disc, a through groove, a sliding rod, a clamping groove block, a spring and a limiting block. Two sets of fixing plates are arranged at the top of the base, and a first rotary disc and a second rotary disc are rotationally connected into the two sets of fixing plates respectively. By rotating the lead screw, due to the fact that the movable block is in sliding connection with the base, the limiting effect is achieved, and the movable block drives the second rotary disc to move so as to adjust the distance between the first rotary disc and the second rotary disc; the clamping grooves and the clamping groove blocks are in one-to-one correspondence all the time through sliding connection of the guide shaft and the second rot
