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.

    本发明公开了一种电力施工用电缆沟盖板提升装置,包括支撑架,所述支撑架的底部四角处固定安装有万向轮,所述支撑架的顶部固定安装有同步升降机构,所述同步升降机构的顶部固定安装有升降架,所述升降架的顶部一端固定安装有控制开关,升降架的内部固定安装有连接杆,连接杆的两端均贯穿连接有两端固定安装于升降架内壁上的滑杆,连接杆的中间位置两侧分别转动安装有另一端均转动安装于升降架内壁上第一滚珠丝杆和第二滚珠丝杆,第一滚珠丝杆和第二滚珠丝杆位于连接杆内的一端分别固定安装有第一锥型齿轮和第二锥型齿轮。本发明利用可旋转的钢杆伸入电缆沟盖板缝隙从底部勾住电缆沟盖板,便于该装置在电缆沟间隙过小时的使用。
