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, there is a need for a drilling machine that reaches the set drilling depth and can automatically stop drilling to meet the requirements of underwater drilling operations.

The invention discloses an opening machine of underwater pressure pipe, which comprises the following parts: case, whose center consists of main shaft and sleeve along axial direction with sliding key connecting between main shaft and sleeve, wherein one filament nut is set in the center of top of main shaft, the feed screw pierces the upper part of main shaft, which mates the filament nut, positive driving box on the case, which contains positive driving motor with at least one group of driving gear between main driving motor and sleeve, wherein the sleeve rotates to drive the feed screw with the rotary speed different from sleeve rotary speed, the staff gauge component is set on the lateral part of case.
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, there is a need for a drilling m...
