Problems solved by technology

Our company purchased ten sets of "little crawler" welding equipment. During the use, we found that when welding stainless steel pipes, heavy iron crawlers are used, and the installation is very laborious.
When appearing on the lower part of the welded pipe on both crawler tracks and steel workpieces, it is extremely easy to fall due to insufficient magnetic force
At the same time, affected by spatter during welding, walking is unstable, resulting in welding defects
Due to the above three main reasons, the purchased equipment is discarded

Embodiment Construction

[0023] like figure 1 , 2 Among them, the 360-degree pipeline automatic welding machine device includes two parallel chains 3 fixed on the pipeline 1 (the two parallel chains 3 form a track) and a movable frame 2 that can move along the three chains. 2 is provided with a welding head 4, the welding head 4 is connected with the welding machine through a connecting line or a connecting pipe, the welding machine can be placed on the movable frame 2, and can also be arranged at other positions. When in use, the welding head of the welding head 4 and the pipeline 1. The positions that need to be welded in the form of rings or partial arcs are in contact with each other;

[0024] The movable frame 2 includes an arc-shaped frame 21 (the arc-shaped line type of the arc-shaped frame 21 is the same as that of the pipeline 1, and different arc-shaped frames 21 need to be selected for different diameters of the pipeline 1 to ensure the quality of welding. The device is aimed at steel pip...

Abstract

The invention relates to an automatic welding machine device and a welding method of a 360-degree pipeline. The automatic welding machine device comprises two parallel chains and a movable frame, wherein the two parallel chains are fixed to the pipeline, the movable frame can move along the chains, and a welding head is arranged on the movable frame; the movable frame comprises an arc-shaped frame, a main driving device and a secondary driving device which are arranged on the arc-shaped frame, at least two main gears are arranged on the front end of the arc-shaped frame, at least two driven gears are arranged on the back end of the arc-shaped frame, the main gears and the driven gears are respectively engaged with the chains, the main gears are driven to rotate by the main driving device by virtue of a rotating shafts, and the driven gears are driven to rotate by the secondary driving device by virtue of a rotating shaft; and the length of the arc-shaped frame is greater than the 271-degree arc length of the pipeline. The automatic welding machine device has the advantages that a welding machine can rotate at 360 degrees along the way edge, enough adhesion is supplied so as to guarantee the welding quality, the installation is simple, and the operation is stable.

Description

technical field [0001] The invention relates to a welding device, especially a welding device for a 260-degree pipeline, which belongs to engineering construction and welding specialty; the invention also relates to a welding method using the device. The invention can better solve the problems of laborious installation, easy falling off, unstable running, unguaranteed welding quality and narrow use area of ​​the conventional automatic welding machine. Background technique [0002] At present, the walking mode of similar welding machines in China mainly adopts the magnetic form. Adsorbed on the welding workpiece by magnetic force. Our company purchased ten sets of "little crawler" welding equipment. During the process of use, we found that when welding stainless steel pipes, we need to use heavy iron crawlers, and the installation is very laborious. When both crawler tracks and steel workpieces appear in the lower part of the welded pipe, it is extremely easy to fall due to...
