Automatic welding trolley for hatch cover guide rail and sealed flat steel of bulk cargo ship

Abstract

The invention discloses an automatic welding trolley for a hatch cover guide rail and a sealed flat steel of a bulk cargo ship. The automatic welding trolley comprises a welding device and a welding trolley body, and the welding device is installed at the exterior of the welding trolley body; a toothed plate linkage rod is driven by an adjusting and fixing mechanism to extrude a spring, and splicing and fixing of two adjustable magnets are achieved; The problem that rail hatch cover accessories are higher is solved by splicing the adjustable magnets, and secondary fixing of splicing of the twoadjustable magnets is achieved through hemispherical contact blocks and fastening springs of limiting blocks; welding errors due to loosening of the adjustable magnets are avoided, and the welding errors of welding work are reduced; and a clamping assembly is fine adjusted through control over a synchronous motor, and the welding errors of welding work of a trolley main body is reduced overall.

Description

technical field [0001] The invention relates to the technical field of welding trolleys, in particular to an automatic welding trolley for bulk carrier hatch cover guide rails and sealed flat steel. Background technique [0002] In order to facilitate manufacturing and transportation, the steel plate factory will roll the steel plate into a uniform size. Therefore, when applying the steel plate, it is necessary to cut, splice, and weld the steel plate to form the steel plate of the required specification; in the traditional steel plate welding process , it is necessary to use a welding torch to melt the welding rod to the connection position of the two steel plates, so as to use the melted welding rod to connect the two steel plates together. Usually, it is necessary to weld the welding position of the steel plate multiple times to ensure the stability of the steel plate welding. [0003] However, the current welding trolley cannot cope with the high attachment of the hatch ...

AI Technical Summary

Problems solved by technology

[0003] However, the current welding trolley cannot cope with the high attachment of the hatch cover, which makes the welding work of the welding trolley difficult, and cannot cope with the deviation of the installation line of the sealing flat steel, which leads to the inability to fine-tune the welding work of the welding trolley and produce errors
