Multifunctional pipeline tapping machine based on plasma cutting

Abstract

The invention relates to a multifunctional pipeline tapping machine based on plasma cutting. The multifunctional pipeline tapping machine comprises a machine shell, a control device, a lifting deviceand a tapping device, and the tapping device comprises a cradle head assembly, a swing arm assembly, a protection assembly, a sliding rail assembly, a cutting assembly and a lifting assembly; the cradle head assembly comprises a cradle head supporting disc, a first hollow rotary table and a rotary table; the swing arm assembly comprises a swing arm and a support plate, and the protection assemblycomprises a box body and a cover plate; an air inlet pipe joint and an air outlet pipe joint are arranged on the box body, and the cover plate is fixed to the lower side of the box body hermetically,so that the cover plate and the box body define a closed air cavity; the cutting assembly comprises an adapter, a plasma cutting gun, a laser range finder, a camera or an infrared range finder, and the vertical distances from the plasma cutting gun and the laser range finder to the axis of the first hollow rotary table are equal; and the lifting assembly is used for lifting a cut pipe wall. The multifunctional pipeline tapping machine has the advantages of the compact structure, light weight, and high functionality and reliability, and the operation efficiency can be improved.

Description

technical field [0001] The invention relates to a pipeline drilling machine, in particular to a multifunctional pipeline drilling machine based on plasma cutting. 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 wears quickly, and the ...
