Petroleum pipeline weld seam trolley automatic walking method

Abstract

The invention discloses a petroleum pipeline weld seam trolley automatic walking method. Two driving wheels are arranged on the bottom face of a welding trolley frame and connected through a wheel axle; the wheel axle is mounted on the welding trolley frame through a suspension frame; a wheel axle bevel gear is arranged on the wheel axle; a transmission shaft for vertical transmission is arrangedon the part, corresponding to the welding trolley frame, of the bevel gear; a lower transmission shaft bevel gear engaged with the wheel axle bevel gear is arranged at the lower end of the transmission shaft; an upper transmission shaft bevel gear is arranged at the upper end of the transmission shaft; a driving motor is arranged on the welding trolley frame; a rotary shaft bevel gear is arrangedon a rotary shaft of the driving motor and is in engagement transmission with the transmission shaft bevel gear; guide rail clamping devices are arranged on the two sides of the welding trolley framecorrespondingly; each guide rail clamping device comprises an adjusting screw, an L-shaped sliding frame, a lower limiting wheel and an upper limiting wheel; the adjusting screws are connected with the upper ends of the L-shaped sliding frames; the L-shaped sliding frames are enabled to move left and right by rotating the adjusting screws; and the lower limiting wheels and the upper limiting wheels which are clamped on guide rails are arranged on the L-shaped sliding frames.

Description

technical field [0001] The invention relates to the technical field of pipeline welding equipment, in particular to an automatic walking method of a petroleum pipeline welding trolley. Background technique [0002] Welding is labor-intensive and working conditions are harsh, especially the welding of special steel. The welding process is complicated, the process is special, and the quality requirements are high. The implementation of traditional welding processes mainly relies on manual operations. Manual operations have the following three characteristics: more smoke and dust , strong heat radiation and high risk. Long-term work in this environment is extremely unfavorable to the welder's body, and it is easy to cause fatigue of the workers, making it difficult to ensure the stability of welding quality. The welding working environment, the complexity of welding products and processes, and the high requirements for welding quality and precision urgently require the realiza...
