Description

Technical Field

[0001] The utility model belongs to the technical field of spiral drill rod welding, in particular to a multifunctional spiral drill rod welding machine. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. In the process of mining coal resources, it is necessary to drill holes with spiral drill rods.

[0003] At present, in the process of production and processing of spiral drill rods, the spiral strips need to be spirally wound on the drill rods by welding. During the use of the existing welding machines for spiral drill rod welding, it is difficult to ensure that the gun head of the welding gun always maintains a tight connection with the connection between the spiral strips and the drill rod, which leads to deviations in the welding position and affects the welding effect. Moreover, most of the existing welding machines for spiral drill rod welding can only weld one type of spiral drill rod. Changes in the length of the spiral drill rod or the width of the spiral strips will affect the normal welding of the welding machine. For this reason, we propose a multifunctional spiral drill rod welding machine. Utility Model Content
