A rapid positioning system for pipe drilling and its positioning method

Abstract

The invention provides a rapid positioning system of pipeline drilling and a positioning method thereof. The rapid positioning system of the pipeline drilling comprises a control mainframe, a drilling device stepping motor, limiting devices, an angle rotating device and an angle measurement device, wherein the drilling device stepping motor is connected with the control mainframe, the limiting devices are arranged on the two sides of a limiting pipeline, the angle rotating device is connected with the control mainframe and drives the pipeline to conduct autorotation around the axis of the pipeline, and the angle measurement device is connected with the control mainframe, arranged on the pipeline and used for measuring the angle of the rotation, around the axis of the pipeline, of the pipeline; the control mainframe comprises a drilling initial position determining module and a drilling horizontal position determining module, the drilling initial position determining module determines the initial reference position before drilling, and the drilling horizontal position determining module determines the real drilling position by taking the reference position as the starting point. Automatic rapid positioning of a drilling hole site at any position can be achieved, the labor is saved, a hole missing failure can not exist, and specially for multipoint irregular drilling, under the situation that the drilling pipeline yield is greatly increased, the drilling quality of the pipeline is further guaranteed.

Description

technical field [0001] The invention relates to a rapid positioning system and a positioning method for pipeline drilling, in particular to a positioning system and a positioning method suitable for fast positioning of drilling positions for multi-point irregular position drilling of pipelines. Background technique [0002] In the manufacture of boiler equipment, there are a large number of pipes that need to be drilled to match the pipes. Taking the steam collecting pipe as an example, a steam collecting pipe with a length of 10m and a diameter of 250mm may need to drill more than 20 holes, and the hole positions are different. The regularity increases the difficulty of drilling. Now all boiler equipment manufacturers adopt manual positioning method. A steam collecting pipe with a length of 10m and a diameter of 108mm needs two workers to work for one day, and there will be quality accidents of leaks, and the work efficiency is low. The prior art method not only seriously ...

Problems solved by technology

Now all boiler equipment manufacturers adopt manual positioning method. A 10m long and 108mm diameter steam collecting pipe needs two workers to work for a day, and there will be quality accidents of leaks, and the work efficiency is low.

The prior art method not only seriously affects the drilling quality, but also seriously affects the output of the steam collecting pipe
