Material frame elevator

The utility model discloses a material frame lifting machine which comprises a motor, a main driving shaft, a branch driving shaft, a longitudinal lead screw, a lifting seat, a lifting platform and a lifting claw. The lifting seats are arranged on the two sides of the material frame conveying rail, and the motor, the main driving shaft, the branch driving shafts and the longitudinal lead screw are sequentially connected. The longitudinal lead screw is vertically arranged on the lifting seat; the lifting platform is arranged on the longitudinal lead screw in a sleeving mode and can be driven by the longitudinal lead screw to ascend and descend. The lifting claw is hinged to the lifting platform and can horizontally swing on the lifting platform. The scheme is simple in structure, easy and convenient to construct and convenient to lift and reform an existing conveying rail. Compared with an existing double-track scheme, the implementation cost is low, and the occupied space is small; and compared with the schem
