Abstract

The invention discloses an axial feed mechanism of a perforating machine. A drill rod main shaft is arranged in a tubular cavity of a tubular body, and the drill rod main shaft connected with a feed mechanism and a rotary driving mechanism performs circumferential rotation and axial displacement movement in a chamber of the tubular body. The axial feed mechanism is characterized in that the lower end of the drill rod main shaft is used for being connected with a cutter, and a shell seat connected with the lower end of the tubular body is connected with a to-be-perforated pipeline A; and the feed mechanism comprises a screw, an upper section rod body of the screw penetrates through a through hole in the middle of a top cover of the tubular body, axial limiting and circumferential rotating fit is formed between the upper section rod body and the through hole, the rod end of the part, outside the top cover, of the screw is connected with torsional power, a threaded section rod body of the part, located below the top cover, of the screw is connected with a nut, circumferential limiting and axial sliding fit is formed between the nut and the inner tube wall of the tubular body, and axial limiting and circumferential rotating connection is formed by the nut and the upper end of the drill rod main shaft.

Description

technical field

[0001] The invention relates to a device for opening through holes on components such as pipelines installed on site, so as to install branch pipelines. Background technique

[0002] In the prior art, it is often encountered that pipes and other similar components have been installed. Due to various reasons, it is necessary to open holes in the pipes to connect to the branch roads. Obviously, at this time, it is necessary to carry out on-site drilling operations. How to realize on-site drilling is The problem that needs to be solved urgently is that it is difficult for large-scale or professional drilling equipment to arrive at the site for operation, and the pipelines installed on site are often in the normal working state of conveying medium, and there are many factors restricting the drilling at this time. Since the diameter of the pipe A to be drilled is sometimes large, it is very common for the pipe diameter to be 300 mm or even larger. For the pipeline...
