It comprises a hand drill, a connector, and a sealing block. The connector has a connecting flange at one end and a straight pipe section at the other end. A transition section is formed between the straight pipe section and the connecting flange. The drill rod of the hand drill extends into the straight pipe section, which is covered with a sealing block and placed at the end of the straight pipe section. The end extending into the straight pipe section is connected to the drill bit of the hand drill, and the end on the sealing block is connected to the control unit of the hand drill. When drilling a hole, a seamless pipe section and a gate valve are connected to the pressurized pipeline, the connecting flange is connected to the gate valve flange, and the drill bit is inserted into the pressurized pipeline. After drilling is completed, the drill bit is pulled out to the joint flange and the gate valve is closed.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 Figure 2As shown, the pipeline branch non-stop pressure opening equipment includes a main pipeline 1, a seamless pipe section 2 is welded on the main pipeline 1, a butt flange 3 is provided on the upper end of the seamless pipe section 2, a sealing gate valve 4 is fixedly installed on the upper end of the seamless pipe section 2, a sealing mechanism 5 is connected to the sealing gate valve 4, the sealing mechanism 5 includes a sealing cone 501 connected to the sealing gate valve 4, a sealing airbag 502 is sleeved on the sealing cone 501, an airbag exhaust port 504 and an airbag air inlet 507 are connected to the sealing airbag 502, a one-way valve 506 is fixedly installed in the airbag air inlet 507, and a hole opening component 6 is provided on the sealing cone 501. The sealing cone 501 on the sealing mechanism 5 is wide at the top and narrow at the bottom and can be inserted into valves of various types to achieve sealing between the driving drill rod 602 and valves of different types, and during the hole opening process, the tapered screw 606 will be screwed into the cut pipe wall block and stuck to prevent the cut pipe wall block from falling into the main pipeline 1.

[0024] like Figure 3 As shown, a sealing mechanism 5 is connected to the sealing gate valve 4, and the sealing mechanism 5 includes a sealing cone 501 connected to the sealing gate valve 4, a sealing airbag 502 is sleeved on the sealing cone 501, and the sealing airbag 502 is connected to an airbag exhaust port 504 and an airbag air inlet 507, a one-way valve 506 is fixedly installed in the airbag air inlet 507, an exhaust hole 505 is opened on the sealing cone 501, and the exhaust hole 505 passes through the sealing cone 501, and a pressure gauge 503 is provided at the upper end of the sealing cone 501.

[0025] Specifically, after the sealing airbag 502 is inflated, it will expand. The expanded sealing airbag 502 will fill the gap between the sealing cone 501 and the sealing gate valve 4, thereby sealing the driving drill rod 602. The sealing cone 501 is wide at the top and narrow at the bottom, so it can be inserted into valves of various types to achieve sealing between the driving drill rod 602 and valves of different types. The exhaust hole 505 can be used to extract the gas in the upper half of the sealing gate valve 4 to prevent the gas from leaking into the air and polluting the environment.

[0026] like Figure 4 As shown, a hole opening component 6 is provided on the sealing cone 501, and the hole opening component 6 includes a drill rod movable sleeve 603 fixed in the sealing cone 501, a driving drill rod 602 is movably installed in the drill rod movable sleeve 603, an electric hand drill 601 is provided at the upper end of the driving drill rod 602, a hole opening drill bit 605 is fixedly installed at the lower end of the driving drill rod 602, a conical screw 606 is fixedly installed in the hole opening drill bit 605, and the end of the conical screw 606 extends out of the hole opening drill bit 605, and the hole opening component 6 also includes a shaft sealing sleeve 604 arranged at the bottom of the drill rod movable sleeve 603.

[0027] Specifically, the electric drill 601 can drive the drill rod 602 to rotate. After the drill rod 602 rotates, it will drive the hole-opening drill bit 605 and the conical screw 606 to rotate. After the hole-opening drill bit 605 and the conical screw 606 rotate, the electric drill 601 can be pressed down to open a hole in the main pipeline 1. During the hole-opening process, the conical screw 606 will be screwed into the cut pipe wall block and stuck to prevent the cut pipe wall block from falling into the main pipeline 1.

[0028] The utility model is a pipeline branch non-stop pressure drilling equipment. In actual use, the seamless pipe section 2 is first welded and installed on the main pipe 1, and then the sealing gate valve 4 can be installed on the seamless pipe section 2 using the docking flange 3. After the sealing gate valve 4 is installed on the seamless pipe section 2, the sealing cone 501 can be inserted into the sealing gate valve 4. After the sealing cone 501 is inserted into the sealing gate valve 4, the airbag air inlet 507 can be used to inflate the sealing airbag 502. After the sealing airbag 502 is inflated, it will expand. The expanded sealing airbag 502 will fill the gap between the sealing cone 501 and the sealing gate valve 4, thereby sealing the driving drill rod 602. The sealing cone 501 is wide at the top and narrow at the bottom, so it can be inserted into valves of various models to achieve sealing between the driving drill rod 602 and valves of different models, which is convenient for users to perform drilling operations. The sealing airbag 502 fills the gap between the sealing cone 501 and the sealing gate valve 4. After the gap is formed, the electric drill 601 can be started. After starting the electric drill 601, it will drive the driving drill rod 602 to rotate.

After the hole-opening drill bit 605 and the conical screw 606 rotate, the electric drill 601 can be pressed down to open a hole in the main pipe 1. During the hole-opening process, the conical screw 606 will be screwed into the cut pipe wall block and stuck to prevent the cut pipe wall block from falling. After entering the main pipeline 1, the drilling drill 605 can be lifted and the sealing gate valve 4 can be closed to block the opened hole. After closing the sealing gate valve 4, the exhaust hole 505 can be used to extract the gas in the upper part of the sealing gate valve 4. After extracting the gas in the upper part of the sealing gate valve 4, the sealing cover on the airbag exhaust port 504 can be opened to discharge the gas in the sealing airbag 502, so that the sealing airbag 502 can be contracted to facilitate the user to remove the entire device from the sealing gate valve 4.
