In recent years, the number of steel pipe towers for power transmission lines has grown rapidly. According to the requirements of the State Grid Corporation of China for the construction of standardized transmission lines and safety production, higher and higher requirements have been put forward for the installation and standardization of steel pipe tower signs.

At present, the installation of domestic transmission line steel pipe tower sign boards mostly adopts pasting, wire binding, and angle steel insertion to the ladder bolts. In these installation methods, since the signboard has no fixing device, the signboard is easily detached from the tower under the action of wind, not only losing its marking function, but also causing certain safety hazards to passers-by. At the same time, due to the special structure of the electric steel pipe tower body, there are safety risks in the operation process of these traditional sign board installation methods. Since the sign board needs to be marked at a position higher than the ground, the operator needs to operate at high altitude. Operators are required to hold both the sign board and some auxiliary tools, so there will be some potential safety hazards in the operation. In addition, the entire installation process takes a long time, the work intensity is relatively high, and the work efficiency is low.

In this technical solution, processing the load-bearing frame with angle steel can make the processing process of the load-bearing frame more convenient, and at the same time ensure the load-bearing strength of the load-bearing frame.

A method for fixing a signboard using a power steel pipe tower signboard fixing device, comprising the following steps:

(1) Before the operation on the tower, the sign board is fixedly connected to the support bracket by bolts, and then the two G-shaped clamps are connected by a piece of iron wire;

(2) Take out the connecting bolts to make a preliminary connection between the supporting bracket and the connecting frame of the ladder and the tower body, clamp one end of the top plate on the supporting bracket with a G-shaped clamp, and bypass the other G-shaped clamp The connecting frame between the ladder and the tower body, and then clamp the other end of the top plate on the support bracket, and initially connect the electric steel pipe iron tower sign board fixing device with the tower body;

(3) Adjust the position of the tongue plate so that the upper end of the tongue plate touches the lower part of the connecting frame between the ladder and the tower body, and then fix the connecting bolt and the supporting bracket through nuts;

(4) Reinforce the nut with a wrench, and remove the two G-shaped clamps on the bracket respectively.

Through the above method, in the process of fixing the sign board, the personal safety of the operators can be effectively guaranteed, and at the same time, the work efficiency can be improved.
