Abstract

The invention discloses a traction system and method for lifting a power transmission line tower. The system and method are suitable for various construction terrains and conditions. The traction system comprises a servo winch, a traction inhaul cable, a tension sensor, a tower material connecting member and the like. In the lifting process of the power transmission line tower, the tower can be stably protected, the situation that the tower tilts excessively due to severe weather such as strong wind and other human factors is prevented, and the safety in the tower lifting process is guaranteed. In-situ lifting transformation is achieved, the range of a line protection area does not need to be changed, complex procedures such as land acquisition and removal, foundation rebuilding and towererecting and stringing construction are avoided, a new tower position is not needed, and the influence on the environment is small. The method effectively solves the problem of safety guarantee in thetower lifting process, solves the problems of low efficiency and low reliability of an existing manual operation mode and method, and has the advantages of being high in controllability, stable and convenient to operate.

Description

technical field [0001] The invention relates to the field of research on the lifting of power transmission line poles and towers, in particular to a traction system and method for lifting power transmission line poles and towers. Background technique [0002] With the continuous development of my country's power grid line construction, the construction technology of pole towers has also been greatly improved. The construction period is shortened under the premise of ensuring the construction quality. At present, the traction of transmission line poles and towers is stable by the stay wires. The stay wire layout of the stay wire towers has There are many ways, the common ones are square pull wires and so on. In areas with relatively flat terrain, the position of the pole cable pit is well determined, and the calculation of the cable length is relatively simple. However, under special terrain conditions such as mountainous areas, due to the undulating terrain, there is a heigh...
