Assembly type welding equipment for building

Abstract

The invention discloses welding equipment for an assembly type building, which comprises a first pipe body and a second pipe body, a welding device is arranged in the first pipe body, and a welding rod is arranged in the welding device; the welding device comprises a first circular wheel and a second circular wheel, and the first circular wheel and the second circular wheel are connected through a plurality of connecting rods. Through the arrangement of the first circular wheel and the second circular wheel, the welding device is fixed between the first circular wheel and the second circular wheel, the multiple first telescopic rods and the multiple second telescopic rods are arranged at the two ends of the main shaft, and the two ends of the first telescopic rods and the two ends of the second telescopic rods penetrate through the first circular wheel and the second circular wheel; a first driving wheel and a second driving wheel are arranged at the penetrating-out end, the first driving wheel abuts against the pipe wall to move in the pipe body direction, and when the first driving wheel moves to the position where welding needs to be conducted, the second driving wheel starts to work, abuts against the pipe wall and does circular motion along the pipe wall.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding equipment for prefabricated buildings. Background technique [0002] When performing butt welding between large ring pipes, usually the ends of the two ring pipes are placed in contact with the rollers first, and the ring pipes are driven to rotate by the rollers. During the rotation, the welding head is used to weld the gap on the outside . For large ring pipes, the inside of the pipe must also be welded. Usually, the welding method is to drill into the pipe for welding, or extend the support arm into the pipe for welding. Although the welding effect is good when the man drills into the pipe, it cannot be stretched. , unable to work for a long time, the work efficiency is low, and the support arm is inserted into the pipe for welding, which is fixed by calculating the distance from the gap to the nozzle for welding, but it cannot ensure that each welding is ...

Problems solved by technology

For large ring pipes, the inside of the pipe must also be welded. Usually, the welding method is to drill into the pipe for welding, or extend the support arm into the pipe for welding. Although the welding effect is good when the man drills into the pipe, it cannot be stretched. , unable to work for a long time, the work efficiency is low, and the support arm is inserted into the pipe for welding, which is fixed by calculating the distance from the gap to the nozzle for welding, but it cannot ensure that each welding is included in the gap, so it is only Rough road welding, poor welding quality, and because the position between the tube and the support arm is not very precise, when welding inside, the distance between the welding tip and the tube changes during the welding process, which affects the welding quality. quality
