The invention discloses an opening and closing type power transmission first-aid repair tower head. The opening and closing type power transmission first-aid repair tower head comprises a tower head connecting device, a first tower head body and a second tower head body, wherein the first tower head body and the second tower head body are symmetrically arranged. The first tower head body comprisesa first supporting crank arm and a first connecting mechanism arranged at one end of the first supporting crank arm. The second tower head body comprises a second supporting crank arm and a second connecting mechanism arranged at one end of the second supporting crank arm. The other end of the first supporting crank arm is rotatably connected to the first end of the tower head connecting device,and the other end of the second supporting crank arm is rotatably connected to the second end of the tower head connecting device. The rotating plane of the first tower head body coincides with the rotating plane of the second tower head body. The first connecting mechanism is used for being fixedly connected with the second connecting mechanism so as to fix the first tower head body and the second tower head body. The first connecting mechanism or the second connecting mechanism is used for hanging a wire through an insulator. The opening and closing type power transmission first-aid repair tower head disclosed by the embodiment of the invention is symmetrical structurally, eccentric force bearing is avoided, and the stability of a first-aid repair tower is improved.
Description
technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to an openable power transmission emergency repair tower head. Background technique [0002] Transmission lines are important lifeline projects, and their safety is directly related to national economic construction and people's lives. It is very important to ensure the normal and reliable operation of power grid transmission lines. The transmission line tower line system has the characteristics of high tower, large span, and strong flexibility. The geometric nonlinearity of the ground wire and the insulator string and the coupling between the tower lines make the effect of the transmission line tower line system on the excitation of typhoon and other environments Very sensitive and prone to damage phenomena such as mechanical vibration, fatigue damage and dynamic collapse. [0003] The southeast coast of my country is not hit by typhoons every year. When a lar...
