Connecting flange intelligent welding robot for petrochemical equipment mounting projects

Abstract

The invention relates to a connecting flange intelligent welding robot for petrochemical equipment installation engineering, which includes a supporting base plate, a fixing device, a welding device and a rotating device. The fixing device is installed on the middle part of the supporting base plate, and the rotating device is located at the center of the fixing device. On the outside, the rotating device is connected with the support base plate, and the welding device is installed on the rotating device; the welding device includes a welding vertical plate, a welding adjustment push rod, a welding adjustment spring, a welding top plate, a welding push rod, a welding bottom plate, and a welding telescopic rod , welding support plate, welding mechanism and welding telescopic spring. The present invention can solve the existing problems of low work efficiency, large work damage, inability to perform multiple fixings to the flange, weak fixation of the flange, and inability to perform automatic welding actions when welding the flange and the steel pipe; The function of multiple stable fixing of the flange and automatic welding of the flange and the steel pipe.

Description

technical field [0001] The invention relates to the technical field of chemical equipment installation, in particular to an intelligent welding robot for connecting flanges used in petrochemical equipment installation engineering. Background technique [0002] Flange connection is to fix two pipes, pipe fittings or equipment on a flange respectively first, then add flange pads between the two flanges, and finally tighten the two flanges with bolts to make them A detachable joint that is tightly combined. The flange is connected to the steel pipe by welding. The steps of flange welding are as follows. First, fix the flange, and then grind the chamfer of the flange before welding. The welding area of ​​the flange is polished smooth, which is beneficial to increase the welding effect. Then place the steel pipe on the flange and fix it. Manually use electric welding equipment to weld the interface between the flange and the steel pipe. The welding must be uniform For welding, t...
