Abstract

The invention relates to a hydraulic pipe orifice assembly reshaping device, which is used for auxiliary operations of welding a pipe orifice assembly on a municipal construction site. The reshaping device comprises a hydraulic positioning disk, a hydraulic reshaping disk, a walking roller wheel and an extra high pressure hydraulic power station system positioned outside the device. The positioning disk positions and compresses welded pipeline inner walls of the device and pipe groups, and the reshaping device uses the reshaping disk to reshape a port at the pipe orifice assembly and is used for on-site pipeline welding construction.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to the technical field of welding medium-diameter pipelines at narrow construction sites, and is a hydraulic nozzle group pair shaping device for positioning and shaping the nozzle group pairs. Background technique [0002] φ400~φ700mm medium-diameter steel pipes are mostly used for laying municipal gas, water supply and drainage pipelines. Due to the short laying distance and small pipe diameter, it is usually not suitable to use all-position automatic welding machines for pipelines, internal welding machines, and medium-frequency heaters for pipelines. Suitable for large-diameter pipes , Automated construction equipment for long-distance pipeline construction, but manual welding is mostly used. In the welding process of the nozzle group pair, the roundness consistency of the welding port is relatively strict. If the roundness consistency accuracy at the nozzle is not...
