The invention relates to the technical field of electric pole hoisting, in particular to a large-bending-moment concrete electric pole hoisting tool. Comprising a lifting arm, two electric sliding seats which are symmetrically connected to the lifting arm left and right in a sliding mode, a winding mechanism arranged on the lower portions of the electric sliding seats and a lifting clamping jaw arranged on the lower portion of the winding mechanism, and the upper portions of the two electric sliding seats are jointly provided with a first stretching type multi-point auxiliary lifting mechanism. Two front and back corresponding auxiliary wing rods in the first stretching type multi-point auxiliary lifting mechanism rotate and stretch out to drive an auxiliary inhaul cable to pull a lifting clamping jaw in the front and back longitudinal direction, so that a lifting point is expanded to the front and back longitudinal direction from the single vertical direction, and meanwhile, the auxiliary wing rods, the auxiliary inhaul cable and the lifting clamping jaw form a triangular limiting structure; therefore, the stress of the concrete pole is effectively dispersed, the concrete pole is stably supported from different directions in the hoisting process, the problems of non-uniform stress and low stability caused by a single hoisting point are avoided, and the hoisting stability is remarkably improved.

    本发明涉及电杆吊装技术领域,具体为一种大弯矩混凝土电杆吊具。包括吊臂、两个左右对称滑动连接在吊臂上的电动滑座、设置于电动滑座下部的收卷机构以及设置于收卷机构下部的吊装夹爪,两个所述电动滑座上部共同设置有伸展式多点辅吊机构一。本发明通过伸展式多点辅吊机构一内的前后对应的两个辅翼杆转动伸出,带动辅拉索从前后纵向上拉动吊装夹爪,从而将吊点从单一的竖直方向扩展到前后纵向,同时使辅翼杆、辅拉索与吊装夹爪形成三角形限位结构,以此有效分散混凝土电杆的受力,确保混凝土电杆在吊运过程中得到来自不同方向的稳定支撑,避免了单一吊点带来的受力不均匀、稳定性低的问题,显著提升了吊运的稳定性。
