Offline cutting equipment for pipeline

Abstract

The invention discloses offline cutting equipment for a pipeline, and belongs to the technical field of pipeline cutting equipment. The offline cutting equipment for the pipeline comprises a guide rail, a pipeline supporting bracket, a portal frame and a cutting saw; the pipeline supporting bracket is arranged on the guide rail, the guide rail and the pipeline supporting bracket are arranged on one side of the portal frame, the middle of the portal frame is provided with a circular hole used for allowing the pipeline to penetrate, a circular rail is arranged along the circular hole, and the cutting saw used for cutting the pipeline does circular motion along the circular rail; the pipeline is arranged on the pipeline supporting bracket, and a clamping device is arranged over the pipeline supporting bracket and used for clamping and fixing the pipeline; and the pipeline supporting bracket is connected with a lifting device and used for adjusting the height of the pipeline on the pipeline supporting bracket. The pipeline is erected on the pipeline supporting bracket, and the pipeline is adjusted to enable the central axis of the pipeline to coincide with the central line of the circular hole of the portal frame through the lifting device while the pipeline supporting bracket moves along the guide rail; and the pipeline is clamped and fixed through the clamping device, the cuttingsaw is started to do circular motion along the circular rail on the portal frame to cut the pipeline penetrating through the circular hole formed in the portal frame, and offline cutting of the pipeline is achieved.

Description

technical field [0001] The invention belongs to the technical field of pipe cutting equipment, in particular to an offline pipe cutting equipment. Background technique [0002] Multi-reinforced steel-plastic composite pressure pipe is a pressure pipe formed by spiral winding and welding of steel-plastic composite strips reinforced by one or more layers of continuous high-strength steel wire mesh and ribs composed of steel strips. Existing multi-reinforced steel-plastic composite pressure pipes do not have offline cutting equipment, and the pipes can only be cut on the production line. Since it is impossible to cut, make pup joints, samples, etc. for the pipes that have been offline, cutting operations on the production line will affect the production progress. Therefore, in order to cut pipes off-line conveniently and quickly, it is urgent to develop a cutting equipment that can meet the pipe size required by special tasks, and can also meet the pipe connection requirements...
