Welding device used for underground engineering waste water pipeline and working method of welding device

Abstract

The invention discloses a welding device used for underground engineering waste water pipelines and a working method of the welding device. The left side of the upper part of a fixed plate is fixedlyconnected with a workpiece holder; a rotating platform is rotatably connected with the upper part of a moving trolley through a rotating shaft fixedly connected with the lower part of the rotating platform; a support pillar is fixedly arranged at the front side of the upper part of the rotating platform; the front side of the support pillar is provided with a vertical slideway; the top part of thesupport pillar is fixedly provided with a vertical driving motor; a welding arm consists of a fixed arm and a sliding arm; the lower part of the left end of the sliding arm is fixedly connected withwelding tongs; the right end of the fixed arm is fixedly connected with reels; one side, near the slideway, of a slider is provided with two sliding chutes II which extend vertically and of which thecross sections are in a shape of T; a sliding rail of which the cross section is in the shape of T is glidingly assembled in each of the two sliding chutes II; upper ends and lower ends of the two sliding rails are respectively and fixedly connected with the upper end and the lower end of the slideway; and two lubricating oil filling devices are fixedly arranged at the front side of the slider ina manner of being respectively corresponding to the sliding chutes II. The welding device is convenient and fast in operating process and high in operation efficiency, and is suitable for welding operation of round workpieces.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a welding device for underground engineering waste water pipelines and a working method thereof. Background technique [0002] In the process of traditional manual welding of pipes, since the outer contour of the pipe is a circumferential surface, the weld seam on its surface is also an arc-shaped surface. During manual welding, either the oxygen cylinder does not move, and the outer contour of the pipe is welded manually. ; Either the pipeline does not move, and the oxygen cylinder is welded around the pipeline to its outer contour. Due to human factors, the welding speed is not stable, resulting in uneven weld seam, low welding efficiency, which affects the welding quality; and working under high temperature and dusty conditions will cause great harm to the human body. [0003] In addition, the traditional manual welding method has problems such as low we...

Problems solved by technology

Due to human factors, the welding speed is not stable, resulting in uneven weld seam, low welding efficiency, which affects the welding quality; and working under high temperature conditions and dusty conditions will cause great harm to the human body

[0003] In addition, the traditional manual welding method has problems such as low welding efficiency, high labor intensity, and unstable welding quality. It has been gradually replaced by automatic welding equipment. The three-claw plate and pneumatic cylinder are used to fix the welded parts, which will cause many problems such as slow delivery time and inability to guarantee welding quality.
