Pipeline pressure tapping machine capable of being remotely controlled

Abstract

The invention discloses a pipeline pressure tapping machine capable of being remotely controlled. The pipeline pressure tapping machine comprises a main machine body, a cutting feeding drive device, a rotary drive device, an advancing and retreating drive device, a hydraulic control device and a remote monitoring system. A first lead screw is in driving connection with the advancing and retreating drive device, a drive sleeve is in driving connection with the rotary drive device, the cutting feeding device is matched with the first lead screw, and the cutting feeding device is matched with the drive sleeve; the rotary drive device, the advancing and retreating drive device and the cutting feeding device are all in control connection with the hydraulic control device; the remote monitoring system comprises a monitoring terminal and a visual probe; and the visual probe is connected with the hydraulic control device, and the monitoring terminal is connected with the hydraulic control device. Manual operation is achieved, long-distance tapping operation can be achieved, and automatic collection of running parameters of main components of the tapping machine is achieved; and in a control room, the running parameters of the main components of the tapping machine can be received, remote safety monitoring is achieved, and safety of equipment and site construction can be improved.

Description

technical field [0001] The invention relates to the field of maintenance, emergency repair and reconstruction of oil, natural gas and refined oil and other gathering and transportation pipelines, in particular to a pipeline underpressure drilling machine for non-stop underpressure operation of the gathering and transportation pipelines. Background technique [0002] In recent years, with the continuous increase of clean energy consumption, the construction scale of natural gas pipelines has increased rapidly. Only by improving safety and drilling efficiency can we meet the ever-increasing pipeline renovation and maintenance workload in the future. [0003] At present, there is an existing pipeline drilling machine under pressure (patent number: 201210126399.9), which adopts an upper-mounted concentric shaft to drive and feed, and is directly driven by two low-speed and large-torque blade motors. The disadvantages include: ①Small output power of the main shaft is small , the...

[0003] At present, there is an existing pipeline drilling machine under pressure (patent number: 201210126399.9), which adopts an upper-mounted concentric shaft to drive and feed, and is directly driven by two low-speed and large-torque blade motors. The disadvantages include: ①Small output power of the main shaft is small , the two motors are difficult to match and the operation is cumbersome during cutting; ②The two motors need to be specially customized, which is expensive; ③The drilling operation is manual and cannot be controlled remotely; ④The operating parameters of the drilling machine cannot be collected automatically, and safety monitoring cannot be performed
