Problems solved by technology

[0003] The traditional pipe drilling machine can be barely used when drilling on land, but when the pipeline drilling operation is carried out underwater, due to the poor visibility underwater, it is generally impossible to directly observe the drilling of the pipeline drilling machine Therefore, a drilling machine that reaches the set drilling depth and can automatically stop drilling is needed to meet the requirements of underwater drilling operations.

Abstract

A perforating machine able to control advance depth for underwater pipeline is composed of a casing, an axial mainshaft and its sleeve pipe, a main drive box with main drive motor and drive gear for driving said mainshaft, an advancing box with mainshaft driving module and locating module for locating the advance depth, and a perforating cutter at the lower end of mainshaft.

Description

technical field [0001] The invention relates to a pipeline drilling machine, in particular to an underwater pipeline drilling machine which can set the drilling depth and automatically stops drilling when the set drilling depth is reached. Background technique [0002] At present, the feeding depth of the pipeline drilling machine is mainly indicated by a scale rod with a scale or an instrument, and the operator judges the drilling depth of the pipeline drilling machine according to the read indication value. When the drilling machine reaches the required drilling depth, the operator needs to operate the pipeline drilling machine to stop drilling. [0003] The traditional pipe drilling machine can be barely used when drilling on land, but when the pipeline drilling operation is carried out underwater, due to the poor visibility underwater, it is generally impossible to directly observe the drilling of the pipeline drilling machine Therefore, a drilling machine that reaches ...
