A welding construction device for building roof steel structure

Abstract

The invention discloses a welding construction device for a steel structure of a building roof. The welding construction device comprises a welding construction platform, a frame body arranged on the welding construction platform, two conveying brackets and two welding ports for cutting the steel structure A cutting head assembly; also includes a central rotating connecting piece, an arc-shaped supporting assembly, a hanging rod piece, a rotating sleeve body and a rotating connecting driving piece; the central rotating connecting piece is arranged on a rotating welding construction platform; the hanging rod The vertical sliding part is arranged on the frame body, and the frame body is provided with a lifting member that drives the suspension rod to rise and fall; two cutting head assemblies are respectively arranged on the rotating sleeve body and the side wall of the suspension rod member, and the two cutting head assemblies Opposite to the two conveying brackets; both the rotating sleeve body and the side wall of the hanger are provided with rotating connection driving parts. The invention has a simple structure, can adjust the connection angle of the steel structure before welding, and can cut the welding end of the steel structure to match the connection angle obliquely, so as to improve the firmness after welding; the operation is convenient and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of building steel structure welding, in particular to a welding construction device for building roof steel structures. Background technique [0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect components or parts. [0003] Some welding of steel structures requires two parts to form a certain angle; therefore, the parts need to be placed at a certain angle before welding and then welded, and in order to make the head connection more tightly, the end of the steel structure needs to be cut obliquely; The angle needs ...

AI Technical Summary

Problems solved by technology

[0003] Some welding of steel structure requires two parts to form a certain angle; therefore, it is necessary to place the parts at a certain angle before welding, and in order to make the head connection more tightly, it is necessary to cut the end of the steel structure obliquely; welding The angle needs to be adapted to the angle of the oblique cutting at the end of the steel structure. The operation is controlled by manual operation, which cannot achieve a tight fit welding, and the whole operation is more cumbersome
