Power transmission tower reinforcing clamps, power transmission tower reinforcing device and power transmission tower reinforcing method

Abstract

The invention discloses power transmission tower reinforcing clamps, a power transmission tower reinforcing device and a power transmission tower reinforcing method. Each power transmission tower reinforcing clamp comprises a main body and a matched part, wherein the main body comprises a clamping part and a connection part which are connected; the clamping part and the matched part are matched to clamp a power transmission tower main material; the joint of the clamping part and the matched part is located in the positions where the clamping part and the matched part extend through the two side edges of the power transmission tower main material. The power transmission tower reinforcing device comprises the multiple power transmission tower reinforcing clamps and a plurality of reinforcing parts. The reinforcing parts are fixed to the power transmission tower main material through the power transmission tower reinforcing clamps, meanwhile, every two adjacent reinforcing parts are in butt joint and are then connected with a shoe plank on a power transmission tower foot plate. The power transmission tower reinforcing method ensures the reinforcing effect of a power transmission tower through combination of finite element analysis and tests. The power transmission tower reinforcing clamps are simple to install, and the power transmission tower reinforcing device and the power transmission tower reinforcing method improve the strength of the power transmission tower.

Description

technical field [0001] The invention relates to the field of engineering maintenance, in particular to a fixture for strengthening a transmission tower, a strengthening device for a transmission tower and a strengthening method thereof. Background technique [0002] Some of the existing transmission towers have been built for a long time and have low design standards. This type of transmission tower has low reliability and poor wind resistance. In bad weather, especially in windy weather, accidents such as falling towers are prone to occur, threatening the safety of personnel, affecting industrial production and people's lives, and causing serious economic losses to the country. [0003] Retrofitting the old transmission tower can strengthen the strength of the transmission tower, such as drilling the main material of the original transmission tower and connecting it with the added sub-main material, but the drilling operation is difficult because the operator needs to climb...

[0002] Some of the existing transmission towers have been built for a long time and have low design standards. This type of transmission tower has low reliability and poor wind resistance

In bad weather, especially in windy weather, accidents such as falling towers are prone to occur, threatening the safety of personnel, affecting industrial production and people's lives, and causing serious economic losses to the country.

[0003] Retrofitting the old transmission tower can strengthen the strength of the transmission tower, for example, drilling holes on the main material of the original transmission tower and connecting with the added auxiliary main material, but the drilling operation is difficult because the operator needs to climb the transmission tower to perform corresponding operations; It is also possible to weld the auxiliary main material on the main material of the original transmission tower, but the operation is also very difficult, and the welding quality cannot be guaranteed. The strength of the original tower body will be weakened during the process, the risk factor is high, and the transformation process is complicated, which prolongs the power outage time of the power grid during the transformation process
