Orbit of gas shielded welding automatic welding trolley in offshore steel structure

Abstract

The invention provides an orbit of a gas shielded welding automatic welding trolley in an offshore steel structure, which is a circular orbit formed by the abutting joint of a semicircular upper half orbit and a semicircular lower half orbit. The upper half orbit and the lower half orbit are respectively a compound guiding orbit comprising guiding orbits at two circular sides and a transmission orbit between the guiding orbits, screw holes are respectively arranged in gaps between the transmission orbit and the guiding orbits at both sides for the threaded connection and the fixation of a magnetic bracket and the orbits. A working mode of gear transmission is adopted so that the automatic welding trolley makes circular motion around a welded piling pipe along the orbit and has good motion stability and high welding quality. The invention has the efficacy of simple and light structure, convenient mounting, rapid and accurate positioning and deformation resistance in use.

Description

technical field [0001] The invention relates to welding equipment, in particular to a running track of a marine steel structure gas shielded welding automatic welding trolley. Background technique [0002] At present, gas-shielded welding is widely used in various steel structure projects due to its advantages of high welding efficiency, convenient operation, and high welding quality. Especially, gas-shielded welding is often used for steel structures in marine engineering. With the continuous development of offshore oil, the amount of construction is also increasing. In order to speed up the construction progress, facilitate construction operations, and reduce the risk of offshore operations, the industry has continuously researched and developed automatic welding equipment suitable for gas shielded welding. The existing automatic welding equipment includes a welding trolley, a welding track and an automatic control mechanism; the welding trolley runs along the pre-laid wel...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing track is mainly reflected in the lack of installation and positioning reference, resulting in inaccurate installation and positioning and long installation time

At the same time, the existing track is mainly designed to carry radial force. When carrying axial force, there is no load bearing and guide rail, which leads to poor transmission stability during operation and cannot meet the requirements of horizontal welding.
