Description

Technical Field

[0001] The utility model relates to the field of fracturing vehicle production, in particular to a crossbeam positioning welding device. Background Art

[0002] A fracturing truck is a device used for shale gas and shale oil extraction. It injects high-pressure liquid into the wellbore to fracture the rock to release the stored natural gas or crude oil. This process is called fracturing. It can increase the permeability of the rock, thereby improving the recovery rate of oil and gas. The frame of a fracturing truck is generally composed of longitudinal beams and cross beams. There are two main types: side beam type and center beam type. The side beam type frame consists of two longitudinal beams on both sides and several cross beams. The longitudinal beams and cross beams are connected by riveting or welding to form a solid rigid frame.

The first rotating gear and the second rotating gear are driven by the rotating motor to rotate, and the meshing action between the second rotating gear and the meshing gear bar is used to realize the rotation function of the rotating disk, which can adjust the direction of the beam and the longitudinal beam, so as to facilitate the welding of the beam; by setting a positioning mechanism, the beam can be placed on the workbench, and the positioning motor is used to drive the positioning threaded rod to rotate, so that the positioning threaded sleeve drives the positioning bracket to move relative to each other, so as to realize the positioning and clamping function of the beam, so as to avoid the error of the welding position due to the movement of the beam during the welding of the beam, thereby affecting the overall stability of the beam.

[0004] However, some harmful fumes will be produced during the welding process, which may affect human health after being inhaled. Utility Model Content
