The invention relates to the technical field of column switch hoisting and relates to the technical field of hoisting. The overall length of a suspension arm of an existing isolating switch cannot be adjusted, and when the existing isolating switch is transferred to a use site, the overall length of the suspension arm is too long and is inconvenient to transfer; the lifting device comprises a supporting frame, a lifting arm, a motor, a speed reducer, a pulley, a winding wheel, a lifting rope, a lifting hook and a storage mechanism, the storage mechanism comprises a servo motor, a lead screw, a lead screw sleeve and a connecting piece, the lifting arm comprises a bottom column, a sliding column and an arm body, and when the lifting device needs to be transferred to a use site, a worker controls the servo motor to start, the lead screw is driven by the servo motor to rotate, and the lifting rope is lifted; due to the fact that the connecting piece is arranged on the lead screw sleeve on the lead screw and detachably connected with the interior of the sliding column, when the lead screw sleeve moves on the lead screw in the direction of the servo motor, the sliding column is driven by the connecting piece to slide in the sliding groove, the sliding column is stored in the sliding groove, and therefore the overall length of the suspension arm is reduced; and the suspension arm is stored and is convenient to transfer.

    本发明涉及柱上开关吊装技术领域,涉及吊装技术领域;现有隔离开关不能调节吊臂的整体长度,在转移使用场地时,吊臂的整体长度过长,不便于转移;本发明包括支撑架、吊臂、电动机、减速器、滑轮、收卷轮、吊绳、吊钩和收纳机构,收纳机构包括伺服电机、丝杆、丝杆套和连接件,吊臂包括底柱、滑动柱和臂体,当需要转移使用场地时,工作人员控制伺服电机启动,通过伺服电机带动丝杆转动,由于丝杆上的丝杆套上设置有连接件,连接件与滑动柱的内部拆卸连接,当丝杆套在丝杆上向伺服电机的方向移动时,通过连接件带动滑动柱在滑槽的内部滑动,使得滑动柱收纳在滑槽的内部,从而降低吊臂的整体长度,在转移使用场地时,对吊臂进行收纳,方便转移。
