High-reliability plasma tapping device for pipeline

Abstract

The invention relates to a high-reliability plasma tapping device for a pipeline. The high-reliability plasma tapping device for the pipeline comprises a holder assembly, a swing arm assembly, a sliding rail assembly and a cutting assembly, wherein the holder assembly comprises a holder supporting disc, a hollow rotary table and a rotary table; the swing arm assembly comprises a swing arm and a support plate; the swing arm is horizontally fixed onto the rotary table; the support plate is perpendicularly fixed onto the swing arm; the sliding rail assembly is vertically installed on the supportplate; the cutting assembly comprises an adapter base connected with the sliding rail assembly; a plasma cutting gun is fixed to the middle of the adapter base; a laser range finder is arranged on oneside of the plasma cutting gun; a camera or an infrared range finder is arranged on the other side of the plasma cutting gun; and the perpendicular distances between the plasma cutting gun and the axis of the hollow rotary table and between the laser range finder and the axis of the hollow rotary table are equal. The high-reliability plasma tapping device for the pipeline has the advantages of being compact in structure, light in weight, high in punching speed, high in functionality and high in reliability, the operation efficiency can be effectively improved, and the use and maintenance costand the labor intensity are reduced.

Description

technical field [0001] The invention relates to a pipeline drilling device, in particular to a pipeline drilling device based on plasma cutting and having an error correction function. Background technique [0002] In the operation and management process of the gas pipeline network, it is often necessary to carry out splicing, cutting and rerouting operations, and pipeline opening is an important process for splicing, cutting and rerouting. At present, the pipe drilling machines used in this field are mainly cylinder knife drilling machines, which have many problems in practical application, mainly in the following aspects: 1. The product is relatively heavy and needs to be specially equipped with a hydraulic station, which is difficult to install and transport. Inconvenient; 2. The efficiency of opening holes is low. It often takes several hours to open a hole, and it requires the cooperation of multiple people to complete it, which is labor-intensive; 3. The barrel knife w...

At present, the pipe drilling machines used in this field are mainly cylinder knife drilling machines, which have many problems in practical application, mainly in the following aspects: 1. The product is relatively heavy and needs to be specially equipped with a hydraulic station, which is difficult to install and transport. Inconvenient; 2. The efficiency of opening holes is low. It often takes several hours to open a hole, and it requires the cooperation of multiple people to complete it, which is labor-intensive; 3. The barrel knife wears quickly, and the use and maintenance costs are high; 4. The diameter of the opening has certain limitations, and the requirements for large-diameter openings often cannot meet the requirements of use
