Abstract
The invention relates to a gas pipeline weld joint protection device, and belongs to the field of oil and gas transmission. The device comprises a chassis, wherein two front wheels are installed on the two sides of the front end of the chassis correspondingly, two rear wheels are installed at the rear end of the chassis, two main hydraulic cylinders are vertically fixed to the upper surface of thechassis, piston rods of the two main hydraulic cylinders are fixed to the same lifting disc, two auxiliary hydraulic cylinders are vertically fixed to the two sides of the lifting disc correspondingly, piston rods of the two auxiliary hydraulic cylinders are fixed to the same transverse rod, vertical rods are vertically fixed to the two ends of the transverse rod correspondingly, rotating rollersare installed on the two vertical rods correspondingly, the distance between the two rotating rollers is smaller than the diameter of a pipeline, two Y-shaped frames are vertically fixed to the two sides of the lifting disc correspondingly, and a rotating shaft is supported by the Y-shaped frames. According to the device, the welding position of the pipeline is protected through a ring, the situation that due to huge pressure of the pipeline, defective weld joints crack, and accidents happen is avoided, meanwhile, manpower and material resources are saved, and oxidation corrosion of the welding position can be avoided.
