The invention relates to a transmission line tower leg charged replacement device and method. The device comprises a base connecting device, a top connecting device and a plurality of supporting frames, wherein lower ends of the supporting frames are fixedly connected with the base connecting device, and upper ends of the supporting frames are fixedly connected with the bottom of the top connecting device. According to the replacement device and method, the base connecting device is fixedly connected with a supporting part of a B-shaped tower, and the top connecting device is fixedly connectedwith a second tower body of the B-shaped tower; the lower ends of the supporting frames are fixedly connected with the base connecting device, and the upper ends of the supporting frames are fixedlyconnected with the bottom of the top connecting device; and the base connecting device is supported by a hydraulic cylinder, the second tower body is driven to move away from the supporting part, thenthe second tower body is replaced, and therefore the damaged second tower body is replaced while power supply to a power line is guaranteed.
Description
technical field [0001] The invention relates to the technical field of replacement of tower legs of overhead transmission lines, in particular to a live replacement device and method for tower legs of transmission lines. Background technique [0002] The safe and stable operation of the tower is the most fundamental embodiment of the intrinsic safety of the transmission line. When the tower of the transmission line is damaged by an external force and the tower is deformed, how to quickly respond to eliminate the tower topple, shorten or repair without power failure is particularly important. [0003] Transmission line towers are divided into different types such as angle steel towers, steel pipe poles, steel pipe towers, cement poles, and "B-type" towers. When the "B-type" tower legs are damaged, the traditional replacement of "B-type" tower legs mainly adopts two methods: the crane method and the herringbone pole holding method. The crane method is to use a crane to lift th...
