The invention discloses a cable trench cover plate lifting device for power construction. The device comprises a supporting frame, wherein universal wheels are fixedly installed at the four corners of the bottom of the supporting frame, a synchronous lifting mechanism is fixedly installed on the top of the supporting frame, a lifting frame is fixedly installed on the top of the synchronous lifting mechanism, a control switch is fixedly installed at one end of the top of the lifting frame, a connecting rod is fixedly installed in the lifting frame, sliding rods with the two ends fixedly installed on the inner wall of the lifting frame are connected to the two ends of the connecting rod in a penetrating manner, a first ball screw and a second ball screw are rotationally installed on the two sides of the middle of the connecting rod respectively, the other ends of the first ball screw and the second ball screw are rotationally installed on the inner wall of the lifting frame, and a first bevel gear and a second bevel gear are fixedly installed at the ends, located in the connecting rod, of the first ball screw and the second ball screw respectively. According to the cable trench cover plate lifting device for power construction, a rotatable steel rod extends into a gap of a cable trench cover plate to hook the cable trench cover plate from the bottom, so that the device is convenient to use when the gap of a cable trench is too small.
