Plate rack type full-automatic pipeline joint welding system

Abstract

The invention discloses a plate rack type full-automatic pipeline joint welding system, which comprises a feeding mechanism, an unloading mechanism and a welding mechanism. The plate rack type full-automatic pipeline joint welding system is characterized in that the feeding mechanism comprises a steel pipe feeding part used for conveying steel pipes, and a groove head feeding part for conveying agroove head. The plate rack type full-automatic pipeline joint welding system has the beneficial effects that the steel pipe feeding part and the groove head feeding part, which are adaptive to a driving rubber wheel and a driven rubber wheel are arranged, automatic feeding is realized through the self-weight rolling of the steel pipe and the groove head, a first section of material blocking air cylinder and a second section of material blocking air cylinder, which alternately extend and retract, are combined with a groove head cabin of which the slope is adjustable so as to finish the stablyintermittent automatic feeding of the steel pipe and the steel groove head, and therefore, the steel pipe and the groove head are coaxially positioned. According to the plate rack type full-automaticpipeline joint welding system, the problem that multi-site regulation and control is required through mechanical arm clamping is avoided, a lever mechanism drives a bottom line friction wheel to tightly press a steel pipe raw material, on one hand, friction force between the steel pipe raw material and the driving and driven rubber wheels is increased, the stability of the steel pipe raw materialis guaranteed, a welding bottom line is connected with the steel pipe, and a condition is provided for welding in a next step.

Description

Technical field: [0001] The invention belongs to the technical field of coal mine welding equipment, and more specifically relates to a frame-type automatic pipeline joint welding system. Background technique: [0002] Welding of pipeline joints is the main two lifelines of coal mines, and with the gradual increase in the distance between roadway mining and coal bunkers, there is a great demand for Feng Shui pipelines. At present, most coal mining enterprises use groovers to squeeze grooves at both ends of pipelines. Groove, this processing method has the following disadvantages: [0003] One is that due to the processing form of the extruded steel pipe, the pipe wall at the groove becomes thinner, and the end of the pipe is easily damaged during recycling, transportation or installation, causing the entire pipe to leak and become unusable. [0004] The second is to use the extruded connecting pipe connection method, which has extremely high quality requirements for the ste...

AI Technical Summary

Problems solved by technology

[0003] One is that due to the processing form of the extruded steel pipe, the pipe wall at the groove becomes thinner, and the end of the pipe is easily damaged during recycling, transportation or installation, causing the entire pipe to leak and become unusable.

[0004] The second is to use the extruded connecting pipe connection method, which has extremely high quality requirements for the steel pipe. If the pipe ends are not aligned, it is easy to be biased and cause damage. It can be used immediately, or it may cause leakage of the pipe and make it unusable.

[0005] Therefore, at present, all the Feng Shui pipelines used by our company are welded pipelines. The large number of used pipes makes the welding and processing unable to meet the production requirements. Manual welding can be used up to 15 lines per day per person; it is far from meeting the needs of current excavation production.
