Lock catch single-gun and double-gun automatic welding equipment

Abstract

The invention discloses lock catch single-gun and double-gun automatic welding equipment. The equipment comprises a spiral welded pipe and a welding tractor, the welding tractor is arranged above thespiral welded pipe, the welding tractor comprises a supporting plate, vacuum tire walking wheels, walking fixed wheels and a gear motor, the walking fixed wheels are arranged on the front side of thesupporting plate, and the vacuum tire walking wheels are arranged on the rear side of the supporting plate. A connecting shaft is arranged between the vacuum tire walking wheels, a speed reducer converter is arranged on the connecting shaft and arranged below the gear motor, the front side of the gear motor is connected to the side face of the supporting plate, a first welding machine welding gunand a second welding machine welding gun which are movably connected are arranged on the front side of the supporting plate, a welding machine head is arranged on the supporting plate, a first weldingmachine wire feeder and a second welding machine wire feeder are arranged on the welding machine head, and the first welding machine welding gun and the second welding machine welding gun are connected with the welding machine head. The equipment is low in potential safety hazard, reduces the welding cost and is suitable for production and popularization.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to an automatic welding equipment with locking single and double guns. Background technique [0002] At present, the common welding methods of spiral pipe pile pipes produced in China mainly include: manual welding carbon dioxide gas shielded welding, manual electrode welding submerged arc welding, large automatic trolley fixed track welding, etc. [0003] The main reasons for the current domestic welding methods include: a large amount of labor is required, time-consuming and labor-intensive, unstable weld bead formation, uneven thickness of the weld gap, unstable consumption of welding wire and welding materials, and a large amount of repairs after welding due to substandard welds. For example, the size of common welds does not meet the requirements, cracks, pores, welding beads, arc craters, undercuts, slag, and incomplete penetration. The normal forming weld bead is smooth in di...

AI Technical Summary

Problems solved by technology

[0005] 1. Many welding personnel and auxiliary personnel are required, and the site is large

[0006] 2. The operation is unstable, the welding time is long, and a single weld requires two people to work at the same time for welding

[0007] 3. Two people work at the same time, the arc damage is large, the site is large, many people weld at the same time, and there are great safety hazards

[0008] 4. A lot of labor is required, time-consuming and labor-intensive, the weld bead is unstable, the thickness of the weld is uneven, and the amount of repair is large

[0009] 5. Waste smoke, strong light, particulate matter, ultraviolet rays, electromagnetic radiation, etc. produced by long-term welding by employees are harmful to the body

[0010] 6. The amount of welding wire used in manual welding is 0.45Kg / m, resulting in unnecessary waste of welding wire

[0011] 7. Due to the single-pass welding operation of the manual welding lock, the uneven welding of the weldment and the uneven heating and cooling can easily lead to the problems of telescopic deformation, angular deformation, bending deformation, wave deformation, and twisting deformation of the steel pipe lock

[0012] 8. At present, the deviation of locks produced by various manufacturers is relatively large, and the existing fixed automatic welding cannot meet the welding lock process on spiral welded pipes.
