Abstract

The invention discloses a drilling tool and method for a sampling hole in a pipeline. The problem that in a pipeline installation site, it is difficult to drill the sampling hole manually in the pipeline is solved. The drilling tool comprises the pipeline (1), a drilling positioning tool bottom plate (3) and an electric drill mounting and positioning tool bottom plate (17). A drilling positioningthrough hole (6) is formed in the drilling positioning tool bottom plate, the drilling positioning tool bottom plate (3) is tied to the pipeline (1) through a stainless steel binding tape (2), an electric drill vertical moving guide rail pipe (7) is fixedly welded to the electric drill mounting and positioning tool bottom plate (17), and an electric drill vertical moving guide groove (8) is formedin the side wall of the electric drill vertical moving guide rail pipe. A top cover (9) is arranged at a top port of the electric drill vertical moving guide rail pipe, a vertical moving rod (11) ismovably arranged in the electric drill vertical moving guide rail pipe, and the head of an electric hand drill is tied to the vertical moving rod through a binding tape. The requirement for drilling in various materials and various pipelines is met.

Description

technical field [0001] The invention relates to a drilling tool for drilling a hole in a pipeline, in particular to a tool and a drilling method for drilling a sampling hole in a pipeline. Background technique [0002] In metallurgy, power generation, chemical industry, coal and other production enterprises, various medium transmission pipelines are generally equipped with thermal sampling holes, and pressure test points are set on the thermal sampling holes to obtain the pressure of the medium on the pipeline in time. The stable and safe operation of pipeline equipment provides first-hand information, and at the same time provides reference parameters for pipeline transportation and maintenance; in order to ensure the accuracy of pressure sampling on pipelines, some pipeline manufacturers install pipeline pressure measurement and sampling holes when pipelines leave the factory However, due to the location of the pipeline installation and the environment, most pipelines need...
