Problems solved by technology

However, the ferromagnetic steel plate track has limitations such as high rigidity, not easy to bend, poor flexibility, not tight fit with the round tube, different tube diameters need to make tracks with different radians, etc., and the practical applicability is poor, especially for small tube diameters. Non-ferromagnetic circular tube ferromagnetic steel plate track cannot be applied

Abstract

The invention discloses a flexible track welding tractor. The flexible track welding tractor is used for a circular pipe to be welded and comprises a chain, a chain wheel, a shaft A, a bearing seat A, an internal thread shaft A, a linear bearing A, a spring A, a pressure bearing A, a hand screw bolt A, a flat plate, a bearing seat B, an internal thread shaft B, a linear bearing B, a spring B, a pressure bearing B, a hand screw bolt B and a driving device A. The chain wheel is fixed to the shaft A, one end of the shaft A penetrates into the bearing seat A through a bearing, the bearing seat A is fixed to the internal thread shaft A, the internal thread shaft A penetrates through the linear bearing A, the spring A and the pressure bearing A to be connected with a screw of the hand screw bolt A, and the linear bearing A is fixed to the flat plate. The flexible track welding tractor can bypass the surface of the circular pipe, and a welding gun fixed to the flexible track welding tractor can weld circular pipe circumferential welds.

Description

technical field [0001] The invention relates to the field of welding equipment. More specifically, the present invention relates to a flexible track welding trolley. Background technique [0002] Automatic girth weld welding of round pipes can use welding machine tools for girth weld welding when the steel pipe can rotate. During the welding process, the welded round pipe rotates, and the welding torch does not need to rotate around the round pipe. However, when the round pipe cannot be rotated, such as the welding of the girth weld during the on-site pipeline laying process, it is necessary to use the welding trolley to drive the welding torch to go around the axis of the round pipe to realize the girth weld of the round pipe. For ferromagnetic steel pipes, usually Magnetic welding trolley, with the help of the magnet on the body of the magnetic welding trolley or the magnetic field force of the magnetic wheel, the welding trolley is adsorbed on the surface of the steel pi...
