Electric transmission line iron tower body welding device

Abstract

The invention discloses a power transmission line iron tower body welding device which comprises a welding head and a base, a disc is rotationally connected to the upper portion of the base, the welding head is installed on a welding plate, a swing frame is arranged on the outer side of the welding plate, and a sliding groove is formed in the side wall of the swing frame and allows the welding plate to slide. The main driving mechanism is used for driving the swing frame to swing, is arranged on the side of the swing frame and can drive the swing frame to swing by 60 degrees during welding; the positioning mechanism is used for assisting positioning of the welding head, is arranged on the side of the main driving mechanism and can drive the welding plate to move before welding, so that the welding head is aligned to the welding point position; the return mechanism can drive the positioning mechanism part to return after single-side welding is completed, and the return mechanism is arranged on the side of the swing frame; the linkage rotating mechanism is used for driving the disc to rotate after single-side welding is completed and can drive the disc to rotate by 90 degrees; automatic welding of the vertical rod and the equilateral angle steel is achieved, manual welding operation is not needed, the manual fatigue is effectively relieved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of transmission line iron tower welding equipment, in particular to a transmission line iron tower tower body welding device. Background technique [0002] A transmission line tower is a tower-like structure for power transmission. Their structural characteristics are that various tower types are space truss structures, and the rods are mainly composed of equilateral angle steel or combined angle steel. The materials are generally Q235 (A3F) and Q345 (16Mn). The entire tower is composed of angle steel, connecting steel plates and bolts, and individual components such as tower feet are welded into a composite by several steel plates. [0003] Most of the existing central structures of transmission line towers are mainly built up by four vertical poles, and two equilateral angle steels are oppositely welded between the vertical poles, that is, the four surfaces formed by the four vertical poles are welded wit...

AI Technical Summary

Problems solved by technology

[0004] In order to maintain the stability of the iron tower body, the four uprights are often inclined gradually from bottom to top to the middle. When welding equilateral angle steel between opposite uprights, since the welding points gradually move closer to the middle from bottom to top, it is often done manually. Manual welding is used on the platform, and there is no automatic welding equipment to assist in realizing this function, and the iron tower is generally very high, and manual welding is extremely exhausting, especially in hot weather and other environments, the labor intensity is high, and the efficiency of manual welding will gradually decrease
