Abstract
A lifting orchestra includes a platen, a platen lifting mechanism, an electric control mechanism and a datum body for support. The electric control mechanism connects with the platen lifting mechanism and the platen lifting mechanism includes a hydraulic cylinder, a transmission frame and a plurality of transmission units arranged on the transmission frame. The piston rod of the hydraulic cylinder is hinged with the transmission frame, and the transmission frame is fixedly connected with a pulley. The upper end of the pulley is provided with rolling wheels. The transmission unit includes a longitudinal push rod, and a link rod. A plurality of positioning stairs is arranged on the working surface in the side corresponding to the pulley of the longitudinal push rod. The rolling wheels on the pulley match the stairs by touching. The working surface of the longitudinal push rod of the utility model is provided with stairs which is in a horizontal state when positioning. When the hydraulic cylinder stops, the weight of the lifting orchestra pressures vertically on the horizontal stair surface so that the pulley avoids bearing the resolving capability of a horizontal direction. Even if the hydraulic cylinder leaks, the shortcoming that the platen dropping caused by the retraction of piston rod can not occur as well.
