[0003] In the prior art, a remote control method for a pipeline pressure - maintained hole opener is disclosed in the patent with the publication number CN114415590A. In this patent, when the hole - opening cutter performs hole opening on the pipeline to be opened, the moving distance and moving direction of the hole - opening cutter towards the pipeline to be opened are obtained through a ranging module, so as to obtain the real - time position of the hole - opening cutter, and it is judged whether the hole - opening cutter deviates during the traveling process according to the real - time position of the hole - opening cutter. When deviation occurs, the deviation angle and deviation distance of the hole - opening cutter are obtained, and the hole - opening cutter is adjusted; after the hole - opening cutter is adjusted, it is judged again whether the hole - opening cutter has deviation according to the adjusted position of the hole - opening cutter. When deviation still exists, the hole - opening cutter is corrected twice, so as to ensure the accurate position of the hole - opening cutter before formal hole opening, so that the holes opened by the hole - opening cutter meet the requirements. However, the above - mentioned patent cannot quickly fix the pressure - maintained hole opener on the pipeline, and the pressure - maintained hole opener is prone to deviate from the pipeline during the processing, thus affecting the hole - opening processing quality of the pipeline.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Please refer to Figures 1 to 3 shown, the present utility model discloses an integrated control opening device, including a pressure tapping machine body 1 and an integrated controller 2 fixed on the pressure tapping machine body 1. Fixing plates 3 are respectively connected to opposite side walls of the pressure tapping machine body 1 through an adjusting device 4. The two fixing plates 3 have a moving stroke of approaching or moving away from each other to clamp the pipeline to be opened when approaching each other.

[0032] In the operation of non-stop pipe tapping, when the traditional motor-driven oil pump works, the conveying pressure is unstable and the regulation performance is poor. A digital display transmitter is installed at the end of the hydraulic oil pipe of this equipment, and a frequency converter is installed on the driving motor. The hydraulic inlet of the equipment is set to achieve variable-frequency constant-pressure oil supply, and all are electrically connected to the integrated controller 2 for control.

[0034] During use, the distance between the two fixed plates 3 is adjusted through the adjusting device 4 so that they are tightly fixed on the outer side of the pipeline, thereby fixing the entire pressure tapping machine body 1 on the pipeline, so as to prevent the pressure tapping machine body 1 from shifting when tapping the pipeline under pressure and ensuring the processing quality.

[0035] In this adjusting device 4, by rotating the lead screw 42 to drive the nut block 43 to be forced to displace, and then driving the adjusting plate housing 44 and the fixed plate 3 fixed thereto to displace, so as to drive the two fixed plates 3 to approach or move away from each other, which can adapt to pipelines with different diameters, so that the two fixed plates 3 are tightly pressed against both sides of the pipeline for fixation, with firm fixation and simple operation.

[0036] Specifically, the fixed plate 3 is arc-shaped, and the diameter of the fixed plate 3 is adapted to the outer diameter of the pipeline. The arc-shaped fixed plate 3 adapted to the pipeline helps to increase the contact area between the fixed plate 3 and the pipeline, thereby making the fixation more firm and reliable.

[0037] Furthermore, anti-slip pads 5 are fixedly connected to the opposite sides of the two fixed plates 3. The anti-slip pads 5 help to increase the friction between the fixed plate 3 and the pipeline, thereby further increasing the firmness and stability between the fixed plate 3 and the pipeline, and further ensuring that the pressure tapping machine body 1 does not shift when tapping the pipeline under pressure.

[0038] Furthermore, the adjusting device 4 further includes a lifting adjustment mechanism 6 disposed within the adjusting plate housing 44.

[0039] By rotating the worm 61 to drive the worm gear 63 to rotate, thereby driving the first gear 64 on the first rotating shaft 62 to rotate, and further driving the double-sided gear to move up and down, the height of the fixing plate 3 can be adjusted to meet the height requirements of different pipe diameters and the pressure tapping machine body 1. This structure has precise and stable positioning and is convenient for adjustment.

[0040] In this application, through the cooperation of the distance adjustment and height adjustment between the two fixing plates 3 in the adjusting device 4, the pressure tapping machine body 1 is adapted to be fixedly connected to pipes of different diameter specifications, which is convenient to use.

[0041] Specifically, in one embodiment, both the first driver 45 and the second driver 66 are handwheels for manual adjustment. In another embodiment, both the first driver 45 and the second driver 66 are motors, and both are electrically connected to the integrated controller 2. The integrated controller 2 controls the start and stop of the motors. This control method and the designed circuit are both mature technologies and will not be introduced in detail here.

[0042] Furthermore, a second rotating shaft 67 is also rotatably disposed on the second side wall.

The guiding rod 69 is inserted into the guiding sliding cavity 651 and is slidably connected thereto, which helps to keep the double-sided rack 65 displaced vertically up and down, and increases the stability of the fixing of the pressure tapping machine body 1.

[0045] Specifically, an arc-shaped notch 11 is provided at the lower end of the outer cylinder of the pressure tapping machine body 1. The arc-shaped notch 11 is adapted to the outer diameter of the pipeline, which is convenient for fitting the pipeline and improves the stability of the pressure tapping machine body 1 during drilling.
