Technical Field

[0001] This utility model relates to the field of power transmission line tower technology, and in particular to a tower body turning and fixing device for power transmission line towers. Background Technology

[0002] Transmission line towers are tower-shaped structures used for power transmission. Their structural characteristics include a space truss structure for all tower types, with members primarily composed of single equilateral angle steel or composite angle steel. The members are connected using coarse bolts, relying on shear force for connection. The entire tower consists of angle steel, connecting steel plates, and bolts. Some components, such as the tower legs, are assembled from several steel plates welded together. Therefore, hot-dip galvanizing for corrosion protection, transportation, and construction are extremely convenient.

[0003] However, existing technologies have some problems: the existing tower body turning and fixing devices do not have a locking structure. After splicing the tower body on the ground, the pole of the spliced ​​tower body section is fixed to the tower body turning and fixing device, but it cannot be locked. During hoisting, it is easy to loosen and slip, which affects its safety. Therefore, it is necessary to provide a tower body turning and fixing device for transmission line towers to solve the above technical problems. Utility Model Content
