Description

Technical Field

[0001] The utility model relates to the technical field of steel structure lightning tower installation, in particular to a gas shielded welding structure used for butt jointing of steel structure lightning towers. Background Art

[0002] Steel structure lightning tower, also known as lightning protection steel tower or lightning elimination steel tower, is a tower structure used to protect buildings from lightning damage. This tower is usually made of round steel, angle steel, steel pipe or single steel pipe, and its height can range from 10 meters to 60 meters. Lightning towers are usually welded in sections in the factory and transported to the site for installation. When installing lightning towers, gas shielded arc welding is usually used to splice the sections. The advantages of this welding technology include high efficiency, good welding quality, low cost and strong practicality.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the lightning tower is welded and connected outdoors, there are many high-altitude operations and the wind speed is relatively high. Due to the characteristics of gas shielded welding, it is easily affected by external airflow, resulting in unstable protective layer, thus generating pores and other welding defects, affecting the welding firmness and further affecting the stability of the lightning tower.

[0005] Therefore, a new gas shielded welding structure for butt jointing of steel structure lightning arrester towers is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a gas shielded welding structure for butt jointing of steel structure lightning towers, so as to solve the problem raised in the above-mentioned background technology that when the lightning towers are welded and butt jointed outdoors, there are many high-altitude operations and the wind speed is relatively high. Due to the characteristics of gas shielded welding itself, it is easily affected by external airflow, resulting in unstable protective layer, thereby generating pores and other welding defects, affecting the welding firmness, and further affecting the stability of the lightning tower.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a gas-protected welding structure for butt-jointing a steel structure lightning arrester tower, comprising:

[0009] A main body assembly, the main body assembly comprising a welding gun body;

[0010] A protective component, the protective component includes a fixed plate connected to the upper end of the front side of the welding gun body by screws, a limiting column movably connected to the fixed plate, an arc-shaped connecting block movably connected to the limiting column, a limiting groove opened in the arc-shaped connecting block, a frame glued to the side of the arc-shaped connecting block, a transparent protective cover connected to the inside of the frame by screws, a connecting column glued to the side of the frame, and a ball bearing sleeved on the connecting column.

[0011] Furthermore, the limiting posts are movably connected in the limiting grooves, and there are four groups of connecting posts and balls, which are symmetrically connected at the four corners of the frame.

[0012] Furthermore, the main body component also includes a bent pipe connected to the front end of the welding gun body by screws, and a protective nozzle sleeved on the front end of the bent pipe.

[0013] Furthermore, the main body assembly also includes a switch movably connected to the lower front end of the welding gun body, and a hose connected to the rear end of the welding gun body by screws.

[0014] Furthermore, the main body assembly also includes a spring connected to the rear end of the welding gun body by screws, and the spring is wrapped on the hose.

[0015] Furthermore, the inside of the hose and the elbow are both connected with a wire feeding tube, and the hose passes through the welding gun body and is connected to the elbow.

[0016] Further, it also includes a locking assembly;

[0017] The locking assembly includes a through hole formed on the fixing plate.

[0018] Furthermore, the locking assembly also includes an adjustment rod integrally connected to one end of the limiting column by injection molding, and a knob glued to the adjustment rod;

[0019] The adjusting rod is screwed in the through hole.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. The utility model provides a protective component. When the welding gun body moves or changes direction during welding, the transparent protective cover fixed in the frame moves accordingly, thereby protecting the weld below the protective nozzle and preventing strong wind from affecting the formation of the weld. The fixed plate, the limiting column, the arc-shaped connecting block and the limiting groove can be used to keep the transparent protective cover always located around the protective nozzle. At the same time, the connecting column and the ball bearing can reduce the movement resistance of the frame.

[0022] 2. The utility model provides a locking assembly. If the welding point is a straight line and the welding gun body does not need to change direction, the knob can be turned to move the adjustment rod along the through hole, tighten the limit column, and drive the arc-shaped connecting block to stick firmly to the fixed plate, so that the frame remains in one position and does not move, which is more conducive to welding operation.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
