Power transmission tower with truss capable of being lifted and falling

Abstract

The invention relates to the field of power transmission towers, and provides a power transmission tower with a truss capable of being lifted and falling. The power transmission tower includes a towerhead, a tower body and tower legs, and the power transmission tower is characterized by comprising a truss group and a linear sliding table module group. The truss group is arranged on the outer sideof the tower body in a sleeving manner; and the linear sliding table module group drives the truss group to move, is fixedly arranged on the side face of the tower body, and connected with the trussgroup. The linear sliding table module group includes first linear sliding table groups and second linear sliding table groups; the first linear sliding table groups are correspondingly and diagonallyarranged on the both sides of the tower body; and the second linear sliding table groups are correspondingly and diagonally arranged on the both sides of the tower body and arranged to be symmetric to the first linear sliding table groups. The truss group includes a first truss, a second truss, and a third truss; and the first truss is fixedly arranged at the bottom of the side face of the towerbody, the second truss is arranged above the first truss and connected with the first linear sliding table groups, and the third truss is arranged above the second truss and connected with the secondlinear sliding table groups. According to the power transmission tower with the truss capable of being lifted and falling, the structure design is ingenious, and adaptability and practicability of thepower transmission tower with the truss capable of being lifted and falling to severe weather are greatly improved.

Description

technical field [0001] The invention relates to the field of power transmission towers, in particular to a power transmission tower with a liftable truss. Background technique [0002] At present, transmission towers, as electric energy transmission carriers, are generally built in areas with very complex terrain and climate environments. The transmission tower line system is extremely sensitive to wind force, which makes it easily affected by wind loads and produces a large dynamic response. , when subjected to wind loads, the cables on the transmission tower will drive the insulator strings to shake in irregular directions, thereby transmitting the force to the tower itself, which in turn aggravates the vibration amplitude of the transmission tower. Long-term use or in windy weather, etc. In special cases, the position of the transmission tower will be shifted or bent, which will limit its application range. Contents of the invention [0003] The invention provides a po...
