Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline opening technology, and in particular to an opening device for thermal pipelines. Background Technology

[0002] Heating pipe networks, also known as heating pipelines, are heating pipes that originate from boiler rooms, direct-fired turbine rooms, heating centers, etc., and lead from heat sources to the heating inlets of buildings. If heating pipes are damaged during use, valves are usually installed by drilling holes in their surfaces.

[0003] Existing thermal pipelines are typically drilled using a live tapping machine. The live tapping machine is connected to the valve via a flange and secured by manual hand support. The vibration generated during drilling can cause hand fatigue for workers, leading to a decrease in drilling accuracy.

[0004] Therefore, when drilling holes in the aforementioned thermal pipelines, a live drilling machine is usually used. Since the live drilling machine is manually positioned, an auxiliary positioning device can be designed to replace manual labor and assist in positioning the live drilling machine. Utility Model Content

[0005] To overcome the problem that existing thermal pipelines are typically drilled using a live tapping machine, which is connected to the valve via a flange and secured by manual support, the vibration generated during drilling can cause hand fatigue for workers, leading to a decrease in drilling accuracy.

[0006] The technical solution of this utility model is as follows: a hole-opening device for a thermal pipeline, comprising a thermal pipeline body; further comprising clamping rings, a sliding rod, a sleeve rod, a connecting rod, an electric push rod, and a base plate. A valve is provided at the middle position of the upper surface of the thermal pipeline body, a positioning tube is provided above the valve, and a pressure-operated hole-opening machine body is provided above the positioning tube. Clamping rings are provided on both the left and right sides of the outer surface of the pressure-operated hole-opening machine body. One end of the sliding rod is connected to the side surface of the two clamping rings away from the pressure-operated hole-opening machine body. A sleeve rod is connected to the side end of the sliding rod away from the clamping rings. A connecting rod is provided to the side end of the sleeve rod away from the sliding rod. Electric push rods are connected to both the front and rear ends of the connecting rod. A base plate is installed on the bottom surface of the electric push rod.

[0007] Preferably, by setting clamping rings, two clamping rings can clamp the body of the hot tapping machine and assist in its positioning, improving the stability during tapping. Furthermore, by setting slide rods and electric push rods, the position of the clamping rings can be adjusted to match the body of the hot tapping machine. This solves the problem that existing hot tapping machines usually use flanges and valve ports for connection without adding auxiliary positioning devices, relying on manual support for stability, which makes it difficult to control stability during use and may cause deviations in the tapping position.

[0008] Preferably, the upper and lower surfaces of the positioning tube are provided with connecting flanges. The upper and lower surfaces of the positioning tube are connected to the upper surface of the valve and the bottom surface of the pressure tapping machine body through the connecting flanges. By providing connecting flanges, it is easy to fix the pressure tapping machine body and improve the positioning accuracy.

[0009] Preferably, fixing plates are installed on both the front and rear surfaces of the two clamping rings, and fixing bolts are inserted between the two corresponding fixing plates. A fixing nut is threaded on the left side of the outer surface of the fixing bolt. The two corresponding fixing plates are fixed by fixing bolts and fixing nuts. By setting fixing bolts and fixing nuts, the two fixing plates can be fixed, thereby fixing the two clamping rings and making the two clamping rings fit against the surface of the pressure tapping machine body.

[0010] Preferably, the outer surface of the slide rod is fitted with the inner surface of the sleeve rod, and the slide rod and the sleeve rod are slidably connected. By setting the sleeve rod, the extension length of the slide rod can be easily adjusted, thereby adjusting the position of the clamping ring to adapt to different pressure tapping machine bodies and improve the adaptability of the device.

[0011] Preferably, the upper surface of the slide rod is provided with an array of positioning screw holes, and the upper surface of the sleeve rod is provided with positioning screws near the slide rod. The slide rod and the sleeve rod are fixed by the positioning screws. By setting the positioning screw holes, after the extension length of the slide rod is determined, the positioning screws can be inserted into the corresponding positioning screw holes and tightened to fix the slide rod and the sleeve rod.

[0012] Preferably, the upper surface of the base plate has positioning holes arranged in a circumferential array. Positioning pins are inserted into the positioning holes. By setting the positioning pins, after the overall position of the device is determined, the positioning pins can be inserted into the positioning holes and driven into the mud to fix the entire device.

[0013] Preferably, the sleeve rod and the connecting rod are welded together, and the front and rear ends of the connecting rod are welded together with the telescopic ends of the electric push rod. By adopting the welding connection method, the connection strength between the sleeve rod and the connecting rod, as well as the connection points between the front and rear ends of the connecting rod and the telescopic ends of the electric push rod, can be improved, thereby improving the overall strength of the device.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting clamping rings, two clamping rings can clamp the body of the hot tapping machine and assist in its positioning, improving the stability during tapping. Furthermore, by setting slide rods and electric push rods, the position of the clamping rings can be adjusted to match the body of the hot tapping machine. This solves the problem that existing hot tapping machines usually use flanges and valve ports for connection without adding auxiliary positioning devices, relying on manual support for stability, which makes it difficult to control stability during use and may cause deviations in the tapping position.

[0016] 2. By setting fixing bolts and fixing nuts, the two fixing plates can be fixed, thereby fixing the two clamping rings and ensuring that the two clamping rings fit snugly against the surface of the pressure tapping machine body. Furthermore, by setting a sleeve rod, the extension length of the slide rod can be easily adjusted, thereby adjusting the position of the clamping rings to adapt to different pressure tapping machine bodies and improve the adaptability of the device. Finally, by setting positioning pins, after the overall position of the device is determined, the positioning pins can be inserted into the positioning holes and driven into the mud to fix the entire device.

Clamping rings 5 ​​are provided on both the left and right sides of the outer surface of the pressure-operated hole-opening machine body 4. One end of the sliding rod 6 is connected to the side surface of the two clamping rings 5 ​​away from the pressure-operated hole-opening machine body 4.

[0024] Please see Figures 1-3 In this embodiment, both the upper and lower surfaces of the positioning tube 3 are provided with connecting flanges 18. Both the upper and lower surfaces of the positioning tube 3 are connected to the upper surface of the valve 2 and the bottom surface of the pressure tapping machine body 4 via the connecting flanges 18. The connecting flanges 18 facilitate the fixing of the pressure tapping machine body 4, improving positioning accuracy. Fixing plates 11 are installed on both the front and rear surfaces of the two clamping rings 5. Fixing bolts 12 are inserted between two corresponding fixing plates 11. A fixing nut 13 is threaded onto the left side of the outer surface of the fixing bolt 12, corresponding to the two fixing plates 11. The fixing plate 11 is fixed by the fixing bolt 12 and the fixing nut 13. By setting the fixing bolt 12 and the fixing nut 13, the two fixing plates 11 can be fixed, thereby fixing the two clamping rings 5, so that the two clamping rings 5 ​​can keep in close contact with the surface of the pressure tapping machine body 4. The outer surface of the slide rod 6 is in contact with the inner surface of the sleeve rod 7. The slide rod 6 and the sleeve rod 7 are slidably connected. By setting the sleeve rod 7, the extension length of the slide rod 6 can be easily adjusted, thereby adjusting the position of the clamping rings 5 ​​to adapt to different pressure tapping machine bodies 4 and improve the adaptability of the device.

[0025] Please see Figures 1-4In this embodiment, the upper surface of the slide rod 6 is provided with an array of positioning screw holes 14, and the upper surface of the sleeve rod 7 is provided with positioning screws 15 near the slide rod 6.

The upper surface of the base plate 10 is provided with a circumferential array of positioning holes 16, and positioning pins 17 are inserted into the positioning holes 16. By setting the positioning pins 17, after the position of the entire device is determined, the positioning pins 17 can be inserted into the positioning holes 16 and driven into the mud to fix the entire device. The sleeve rod 7 and the connecting rod 8 are welded together, and the front and rear ends of the connecting rod 8 are welded together with the telescopic ends of the electric push rod 9. By adopting the welding connection method, the connection strength between the sleeve rod 7 and the connecting rod 8 and the connection points between the front and rear ends of the connecting rod 8 and the telescopic ends of the electric push rod 9 can be improved, thereby improving the overall strength of the device.

[0026] During operation, the connecting flange 18 facilitates the fixing of the pressure tapping machine body 4, improving positioning accuracy.

Furthermore, by setting the positioning nail 17, after the overall position of the device is determined, the positioning nail 17 can be inserted into the positioning hole 16 and driven into the mud to fix the entire device. In addition, by adopting a welding connection, the connection strength between the sleeve rod 7 and the connecting rod 8, as well as the connection points between the front and rear ends of the connecting rod 8 and the telescopic end of the electric push rod 9, can be improved, thereby improving the overall strength of the device.

[0027] Through the above steps, by setting clamping rings 5, the two clamping rings 5 ​​can clamp the body 4 of the hot tapping machine and assist in its positioning, thereby improving the stability during tapping. Furthermore, by setting slide rods 6 and electric push rods 9, the position of the clamping rings 5 ​​can be adjusted to match the body 4 of the hot tapping machine. This solves the problem that existing hot tapping machines usually use flanges and valve ports for connection without adding auxiliary positioning devices, and rely on manual support for stability, making it difficult to control stability during use and potentially causing deviations in the tapping position.
