A rack-type automatic pipeline joint welding system

Abstract

The invention discloses a pan-type automatic pipeline joint welding system, which includes a feeding mechanism, a discharging mechanism and a welding mechanism, and is characterized in that the feeding mechanism includes a steel pipe feeding part for conveying steel pipes and a groove head for conveying groove heads Feeding part; the beneficial effect of the present invention is: the steel pipe feeding part and the groove head feeding part adapted to the driving rubber wheel and the driven rubber wheel are set, and the automatic feeding is realized through the self-weight rolling of the steel pipe and the groove head, combined with alternate expansion and contraction The first-section stopper cylinder, the second-section stopper cylinder and the grooved head warehouse with adjustable slope complete the intermittent automatic feeding of the steel pipe and the grooved head, and then position the steel pipe and the grooved head coaxially; The clamping of the manipulator requires multi-point control. The bottom line friction wheel is driven by the lever mechanism to compress the steel pipe raw material. On the one hand, the friction force between the steel pipe raw material and the driving and driven rubber wheels is increased to ensure the stability of the steel pipe raw material. The bottom line is connected with the steel pipe to provide conditions for the next step of welding.

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 steel...

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.
