Multi-angle overturning welding device for long-distance large-diameter jacking pipe

Abstract

The invention discloses a multi-angle overturning welding device for a long-distance large-diameter jacking pipe, relates to the technical field of jacking pipe welding equipment, and solves the problems that according to an existing welding device, a welder needs to manually knock a welding slag coating after welding, the efficiency is low, manpower is wasted, and hand fatigue of the welder is likely to be caused by frequent knocking actions. The multi-angle overturning welding device for the long-distance large-diameter jacking pipe comprises a base and a positioning square rod, wherein thebase comprises a V-shaped supporting plate, vertical supporting rods, a lead screw and a connecting top plate, the base is integrally of an I-shaped structure, and the two vertical supporting rods aresymmetrically welded to the middles of the front side and the rear side of the base; and two gear rings are rotationally inserted and supported at the top ends of the two vertical supporting rods, and the front end side gear ring is movably mounted. According to the multi-angle overturning welding device, a knocking rod can slide left and right along a rail square rod through a square sliding sleeve to be adjusted and is inserted and positioned through the rail square rod, and the device is suitable for knocking welding slag on butt welds at different positions, is flexible to use and wide inapplication.

Description

technical field [0001] The invention relates to the technical field of pipe jacking welding equipment, in particular to a multi-angle flip welding device for long-distance and large-diameter pipe jacking. Background technique [0002] In the penstock pipe laying project, there are generally two methods: one is the open large-scale excavation method, that is, the ground is fully excavated by the excavator, the pipe is placed down for counter-welding, and the weld is inspected after passing the inspection. , and then refill; the other way is that when limited by the specific environment, such as crossing highways, railways, buildings, rivers, green belts, etc., it is not possible to use large excavation to lay pipelines, and only trenchless underground can be used. Pipe jacking construction method, that is, pipe jacking construction. Regardless of the pipeline laying method, it is necessary to connect adjacent pipelines when laying pipelines. When using concrete pipelines, yo...

Problems solved by technology

[0005] The purpose of the present invention is to provide a long-distance and large-diameter pipe jacking multi-angle flip welding device to solve the inconvenient butt clamping and positioning operation of two pipe jackings proposed in the background technology above, and the welder needs to knock manually after welding. The efficiency of welding slag coating is low, a waste of manpower, and frequent tapping actions can easily cause hand fatigue of the welder
