Problems solved by technology

However, people found in actual use that due to the processing error of the steel cylinder itself and the slight deformation during the transfer process, the butt joints often appear to be staggered after the steel cylinder is placed. At this time, it must be adjusted manually (such as adding Gaskets, etc.), which has a great impact on the labor intensity of the operator and the safety of the operation

Abstract

The invention discloses an auxiliary device for large-caliber steel cylinder butt joint, and relates to the field of steel cylinder machining, in particular to the auxiliary device for large-caliber steel cylinder butt joint. The auxiliary device for large-caliber steel cylinder butt joint is simple in structure and convenient to adjust and weld, and improves the machining quality. The auxiliary device for large-caliber steel cylinder butt joint comprises a pair of support sets and a pressing mechanism; and the pair of support sets are used for supporting a first steel cylinder and a second steel cylinder correspondingly. The auxiliary device realizes butt joint during sliding of the steel cylinders, achieves a reliable support effect, and improves the welding reliability.

Description

technical field [0001] The invention relates to the field of steel cylinder processing, in particular to an auxiliary device for butt jointing of large-diameter steel cylinders. Background technique [0002] With the application of large-scale machinery and equipment in construction, large-diameter steel cylinders are widely used in roads, bridges and other structures; due to the large diameter of steel cylinders, when production and processing are docked, two steel cylinders are usually placed on two sets of supports Roller, so that the two steel cylinders are connected end to end (with a certain gap), and then the outer wall of the steel cylinder is manually positioned by spot welding with the outside of the steel cylinder. However, people found in actual use that due to the processing error of the steel cylinder itself and the slight deformation during the transfer process, the butt joints often appear to be staggered after the steel cylinder is placed. At this time, it m...
