Portable pipe welding robot

Abstract

The invention provides a portable pipe welding robot which comprises two car bodies with opposite round pipe outer walls. The bottoms of the car bodies are provided with rollers, the rollers are magnetically connected with round pipes, double-speed chains are connected to the two sides of the car bodies, the double-speed chains of the car bodies are connected through tightening structures, weldingassemblies are arranged on the car bodies, each welding assembly comprises a horizontal sliding block and a longitudinal sliding block, the longitudinal sliding blocks are provided with clamps, welding guns are arranged in the clamps, the car bodies are further provided with laser weld bead trackers, and the laser weld bead trackers, the welding assemblies and the car bodies are all controlled remotely. The portable pipe welding robot has the beneficial effects of reasonable design, the simple structure, safety, reliability and capacity of achieving automatic welding of the round pipes.

Description

technical field [0001] The invention relates to the technical field of pipeline welding equipment, in particular to a portable pipeline welding robot, in particular to a portable round pipe welding device. Background technique [0002] With the development of the times and technology, more and more sophisticated production equipment appears in the modern industrial production process. Production equipment is becoming more and more advanced, and the structure is becoming more and more complex. Standard parts in the traditional sense are still of great significance and can reduce production costs. [0003] Round pipes are widely used in our production and life, and can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes. In the on-site construction process of pipeline installation, it is often necessary to use pipe-to-pipe on-site butt welding. At present, the commonly used pipe-to-pipe...

Problems solved by technology

In the on-site construction process of pipeline installation, it is often necessary to use pipe-to-pipe on-site butt welding. At present, the commonly used pipe-to-pipe welding methods include two solutions. One is manual welding. This method is slow in efficiency and poor in quality. It is stable and has high requirements for the technical quality of the workers themselves. During the welding process of the round pipes, the ends between the two round pipes are usually spot welded manually, and then the gap between the round pipes is welded. During the welding process, the round tube needs to be manually rotated according to the welding progress. The work efficiency is low and the work intensity is high. It is difficult to meet the welding of large quantities of round tubes and affect the welding quality.

The other is track semi-automatic welding, which is to build a track on the pipe, and then let the rail car carry a welding torch to weld around the circumference of the pipe. The advantage of this method is that it does not require high technical quality of workers and the quality is relatively stable, but the disadvantage is that the track The construction is relatively troublesome, and the welding efficiency cannot be effectively improved
