Rapid stripping machine for three PE (polyethylene) anticorrosion layers for steel pipe

Abstract

The invention discloses a rapid stripping machine for three PE (polyethylene) anticorrosion layers for a steel pipe, which belongs to the technical field of pipeline construction. The rapid stripping machine comprises a split cutting beveller, a hydraulic drive device, a follower rest assembly, a tool rest assembly and a connector assembly, wherein the hydraulic drive device is connected with the split cutting beveller, the follower rest assembly is connected with the split cutting beveller through the connector assembly, and the tool rest assembly is mounted on the connector assembly and provided with a turning tool. The follower rest assembly and the split cutting beveller are sleeved on the outer surfaces of the PE anticorrosion layers for the steel pipe and circumferentially move along the outer surfaces of the PE anticorrosion layers, and then the turning tool on the tool rest assembly is driven to cut the PE anticorrosion layers. Without hot work of a pipeline in service, the three PE anticorrosion layers are mechanically and automatically stripped, the labor amount of constructors is greatly reduced, and automation of pipeline repair / modification is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a three-layer PE anticorrosion layer rapid peeling machine for steel pipes. Background technique [0002] In the current domestic and foreign pipeline repair and renovation, the stripping of the anti-corrosion layer of the pipeline is a common basic work. Three-layer PE is more and more popularized and used because of its adhesion and good integration with steel pipes in pipeline anticorrosion, but this poses a problem for the removal of PE anticorrosion layer in pipeline repair construction. In pipeline emergency repair / transformation sites, methods such as roasting and knife cutting are usually used to peel off the PE anti-corrosion layer on the pipeline in service. This method takes a long time, is labor-intensive, and has a high risk factor; The PE anti-corrosion layer on the non-service pipeline is stripped by other methods. The equipment used in this method i...

Problems solved by technology

[0003] In order to solve the problems of long working time, high labor intensity and inconvenient operation for stripping the PE anti-corrosion layer of steel pipes, the present invention provides a three-layer PE anti-corrosion layer rapid stripping machine for steel pipes. The rapid stripping machine includes split cutting Beveling machine, hydraulic drive device, heel tool rest assembly, tool rest assembly and connector assembly; the hydraulic drive device is connected to the split type cutting and beveling machine, and the heel tool rest assembly is connected through the connector assembly be connected with the split-type cutting and beveling machine, the tool rest assembly is installed on the connector assembly, and a turning tool is arranged on the knife rest assembly; The petal-type cutting and beveling machine is set on the outer surface of the PE anti-corrosion layer for steel pipes. The heel tool holder assembly and the split-type cutting and beveling machine make circular motions along the outer surface of the PE anti-corrosion layer to drive the tool holder assembly. Chengshang's turning tool cuts the three-layer PE anti-corrosion layer of the steel pipe
