Portable auxiliary supporting frame welding fixture suitable for angle steel tower installation

Abstract

The invention discloses a portable auxiliary support frame welding fixture suitable for angle steel tower installation, comprising a base, a guide groove is arranged on the base, a fixed support plate is arranged at one end of the guide groove, and a movable support plate is arranged at the end of the guide groove away from the fixed support plate , a moving part is arranged under the moving support plate, a screw rod is arranged through the moving part, the moving part and the screw rod are located in the guide groove, the moving part is screwed with the screw rod, and the fixed support plate and the moving support plate are hinged with a rotating support plate, The angle steel is placed between the fixed support plate and the movable support plate, the screw rod is rotated to compress the fixed support plate and the movable support plate, and the angle of the rotating support plate is adjusted according to the angle of the angle steel. The invention can clamp the angle steel between the fixed support plate and the movable support plate, the angle steel is not easy to generate large vibration, and there is no large gap between the two angle steels, which ensures the welding quality, and can be used according to the angle of the angle steel Adjust the angle of the rotating support plate, and its application range is wider.

Description

technical field [0001] The invention relates to a fixing device, in particular to a welding fixture for a portable auxiliary support frame suitable for installing an angle steel tower. Background technique [0002] Iron tower refers to a high tower made of steel materials. The independent steel structures erected to bear a certain air load or communication function are collectively referred to as iron towers. The current iron towers are generally made of angle steel and steel plate parts, which are combined with bolts, but only a small amount of welded parts are used locally, such as hanging wire angle steel reinforcement plates, etc. The base plate is generally welded by electric welding. The upper parts of the tower are generally hot-dip galvanized for corrosion protection. Iron towers are usually divided into the following categories from the type of steel materials: 1. Angle steel tower: the main material and web are mainly made of angle steel. Octagonal towers, the mo...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that when angle steels are welded, especially for 30° angle steels, 45° angle steels and 60° angle steels, large gaps are likely to occur between the angle steels, resulting in poor welding quality and even scrapped angle steels , the purpose is to provide a portable auxiliary support frame welding fixture suitable for angle steel tower installation, to solve the above problems
