The invention relates to the technical field of transformer substations, and discloses a transformer substation indoor cable trench cover plate lifting device which comprises a shell, a rotating shaft, a judging mechanism, an extruding mechanism and a triggering mechanism, the rotating shaft is movably connected to the inner side of the shell and fixedly connected with the output end of a driving motor, the model of an external motor is Y280S-6, and the rotating shaft is connected with the output end of the driving motor. The inner wall of the shell is movably connected with the judgment mechanism, the judgment mechanism is used for judging the friction force of the surface of the rotating shaft, and the inner wall of the shell is movably connected with the extrusion mechanism. According to the hoisting device for the indoor cable trench cover plate of the transformer substation, the triggering mechanism is changed by judging the friction force borne by the mechanism, so that the phenomenon that a bearing rotating shaft connected with a driving motor is jammed is avoided, friction between a bearing and a shell on the outer side is prevented, heat generated by the bearing is avoided, the service life of the hoisting device is prolonged, and the cost is reduced. And manual lubricating liquid adding is avoided, time and labor are saved, and the working efficiency of the lifting device is improved.

    本发明涉及变电站技术领域,且公开了变电站室内电缆沟盖板起吊装置,包括壳体、转轴、判断机构、挤压机构、触发机构,所述壳体的内侧活动连接有所述转轴,所述转轴与驱动电机的输出端固定连接,外接电机型号为Y280S‑6,所述壳体的内壁活动连接有所述判断机构,所述判断机构用于判断所述转轴表面的摩擦力,所述壳体的内壁活动连接有所述挤压机构。该变电站室内电缆沟盖板起吊装置,通过判断机构受到的摩擦力,进而使得触发机构发生变化,实现了避免驱动电机连接的轴承转轴发生卡涩的现象,防止轴承与外侧的壳体会产生摩擦,避免轴承本身产生热量,提高了起吊装置的使用寿命,避免人工手动对其添加润滑液,省时省力,提高了起吊装置的工作效率。
