Auxiliary device for welding inner web on box type steel column

Abstract

The invention discloses an auxiliary device for welding an inner web on a box type steel column, and relates to the technical field of box type steel column manufacturing. The auxiliary device comprises a supporting mechanism, conveying mechanisms, clamping mechanisms and preheating mechanisms, wherein the supporting mechanism is arranged close to the lower part and is used for supporting the box type steel column; the conveying mechanisms are symmetrically arranged on the front side and the rear side of the supporting mechanism in the lower part and used for conveying the box type steel column; the clamping mechanisms are symmetrically arranged on the front side and the rear side of the supporting mechanism in the upper part and used for clamping an inner web; and the preheating mechanisms are symmetrically arranged on the left side and the right side of the supporting mechanism in the middle and used for preheating the box type steel column. In conclusion, when the inner web on the box type steel column is welded, the box type steel column can be supported, conveyed and preheated, and the inner web can be clamped. The auxiliary device for welding the inner web on the box type steel column has the advantages of being ingenious in design, reasonable in structure, low in manufacturing cost and convenient to use and maintain.

Description

technical field [0001] The invention relates to the technical field of manufacturing box-shaped steel columns, in particular to an auxiliary device for welding inner webs on box-shaped steel columns. Background technique [0002] Welding inside the box-shaped steel column is more difficult because of the lack of internal space. At present, there are already automatic welding equipment inside the box-shaped steel column on the market. However, when welding inside the box-shaped steel column, if the steel plate is a thick plate, it needs to be welded before welding Preheating, there is no preheating equipment for this kind of box column, so we need to research this kind of equipment. [0003] There are two existing preheating methods, one is to use the flame method for heating, the advantage of this method is that the heating is fast and convenient, but the heating of the base material is uneven; the other method is to use the ceramic liner for heating. Heating, the advantage...

[0003] There are two existing preheating methods, one is to use the flame method for heating, the advantage of this method is that the heating is fast and convenient, but the heating of the base material is uneven; the other method is to use the ceramic liner for heating. Heating, the advantage of this method of heating is that the base metal is heated more evenly, but the heating is slower and the use is more complicated
