The invention relates to the technical field of electric power overhaul, and discloses an electric power overhaul safety lifting device which comprises an outer frame arranged in an up-down penetrating mode, universal wheels installed at the four corners of the bottom face of the outer frame and a protection frame arranged above the outer frame, and two positioning plates are horizontally arranged in the outer frame up and down. According to the lifting device for electric power overhaul safety, the protection mechanism is arranged, a protection part in the protection mechanism is used for achieving anti-falling safety guarantee on a positioning plate on the upper portion, when the lifting device works, a rotating cylinder is rotated to control a rotating disc to rotate, a movable tooth block in a moving column on the upper portion is engaged with a tooth plate, and the safety of electric power overhaul is improved. According to the principle that the bottom end face of a movable tooth block is inclined, the height of an upper positioning plate can be kept unchanged when a fault occurs, the possibility of personnel injury is reduced, before the upper positioning plate descends, a rotating cylinder is rotated again, the movable tooth block is retracted, and a lower moving column with a friction plate extends out and rubs against the side face of the tooth plate, so that the working efficiency is improved. And the upper positioning plate stably descends.

    本发明涉及电力检修技术领域,且公开了电力检修安全用升降装置,包括上下贯通设置的外框,安装在外框底面四角的万向轮,和外框上方设置的防护框,所述外框内部上下水平设置有两个定位板。该电力检修安全用升降装置,通过设置保护机构,利用保护机构内部的防护部对上方的定位板起到防掉落的安全保障,在该设备工作时,旋转转动筒控制转动盘转动,使得上方移动柱内部的活动齿块与齿板相互啮合,利用活动齿块底端面倾斜的原理,使得上方定位板在故障时能够保持高度不变,减少人员受伤的可能性,在上方的定位板降下之前,再次旋转转动筒,使活动齿块收回,并使下方带有摩擦片的移动柱伸出并与齿板侧面摩擦,使上方定位板稳定下降。
