[0001] This utility model relates to the field of hole-opening device technology, and in particular to a hole-opening device for water supply pipeline production. Background Technology

[0002] The drilling device for water supply pipelines is a key piece of equipment to ensure efficient and precise construction of pipeline systems. Its core function is to quickly and stably drill precise holes in water supply pipelines to enable functions such as pipeline connection and branch pipeline access, ensuring the integrity and smooth flow of the entire water supply network, and improving construction efficiency and quality. It has the following structure:

[0003] 1. Outer shell: The outer shell serves as the basic framework of the entire device;

[0004] 2. Motor: Provides strong and stable power for the rotation of the drill bit;

[0005] 3. Drill bit: The drill bit is the key component that directly acts on the water supply pipe to complete the drilling task;

[0006] 4. Connecting flange; used to connect the opening device to the valve on the water supply pipe to be opened.

[0007] In the production of water supply pipelines, it is sometimes necessary to connect two pipelines. When connecting a new pipeline, drilling is often required. If there is still water in the old pipeline, to prevent water leakage, the valve is first sealed to the old pipeline to ensure that the water flow is cut off. Then, the flange is connected to the other end of the valve. Due to the location of the original pipeline and the unevenness of the ground, the holes of the flange and the holes of the valve and other components sometimes cannot be aligned. The operator has to manually adjust the drilling device to align the holes. The drilling device itself has a certain weight, and manual adjustment is physically demanding, which increases the intensity of operation and leads to low drilling efficiency. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this utility model provides a drilling device for water supply pipeline production. It solves the problem that in water supply pipeline production, sometimes it is necessary to connect two pipelines. Due to the location of the original pipeline and uneven ground, the holes on the flanges and valves sometimes cannot align. Operators must manually adjust the drilling device to align the holes, which is physically demanding and leads to low drilling efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A perforation device for water supply pipe production includes a housing, an outer flange, and a rotating ring for adjusting the position of the flange. An annular groove is formed on the inner side of the flange, and the flange is rotatably connected to the outer side of the rotating ring via the annular groove. An installation pipe is fixedly installed on the inner side of the rotating ring and sleeved onto the outer side of the housing. Two fixing mechanisms for fixing the installation pipe are provided on the outer side of the housing. Each fixing mechanism includes a locking block, a limiting plate, a square nut, and a bolt. The locking block is located on the outer side of the housing. One end of the limiting plate is slidably connected to the outer side of the locking block. The square nut is located on the outer side of the locking block. The bolt is threaded into the inside of the square nut and used to restrict the movement of the limiting plate. A limiting groove is formed on one side of each limiting plate corresponding to the installation pipe. The other end of the limiting plate is locked into the inside of the limiting groove and used to fix the installation pipe.

[0011] Preferred configuration: Each clip has an external mounting groove, a square nut is engaged inside the mounting groove, and each clip has a through hole on the side corresponding to the mounting groove, through which a bolt is threaded into the square nut.

[0012] Preferably, the outer shell has a storage slot on one side corresponding to each card block, the card block is slidably connected to the inside of the storage slot, and a spring is fixedly connected inside each storage slot, with the card block fixedly connected to the outside of the spring.

[0015] 1. The flange is installed on the outside of the housing by a fixing mechanism to facilitate the replacement of flanges of different specifications or models, thereby adapting to different valves. When the holes on the flange cannot be accurately aligned with the holes on the valve or other components, the flange is rotated to align the holes on the flange with the valve, without moving the entire device, reducing the intensity of manual operation. This makes it easier for workers to quickly align the holes on the flange with the holes on the valve or other components, thereby maintaining drilling efficiency.

[0016] 2. When the bolt cannot be properly disconnected from the square nut, press the fixing block to separate it from the built-in groove, and the locking block can be moved upward. This provides another way to disconnect the limiting plate from the limiting groove, increasing the flexibility of the fixing mechanism. Attached Figure Description

Due to the location of the original pipeline and the unevenness of the ground, the holes of the flange and valves and other components sometimes cannot be aligned. Operators have to manually adjust the drilling device to align the holes. The drilling device itself has a certain weight, and manual adjustment is physically demanding, which increases the intensity of operation and leads to low drilling efficiency.

[0025] Example

[0026] As shown in Figures 1, 2, 3, 4, and 5, the technical solution in this application effectively solves the problem that in water supply pipeline production, sometimes it is necessary to connect two pipelines. Due to the location of the original pipeline and uneven ground, the holes of the flange and valves and other components sometimes cannot be aligned. Operators must manually adjust the drilling device to align the holes. The drilling device itself has a certain weight, and manual adjustment is physically demanding, leading to increased operational intensity and low drilling efficiency. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a hole-opening device for water supply pipeline production, including a housing 1, a flange 2 disposed on the outside of the housing 1, a rotating ring 3 disposed on the outside of the housing 1 for adjusting the position of the flange 2, an annular groove 4 opened on the inner side of the flange 2, the flange 2 being rotatably connected to the outside of the rotating ring 3 through the annular groove 4, an installation pipe 5 being fixedly installed on the inner side of the rotating ring 3, the installation pipe 5 being sleeved on the outside of the housing 1, two fixing mechanisms for fixing the installation pipe 5 disposed on the outside of the housing 1, each fixing mechanism including a locking block 6, a limiting plate 7, a square nut 8, and a bolt 9, the locking block 6 being disposed on the outside of the housing 1, one end of the limiting plate 7 being slidably connected to the outside of the locking block 6, the square nut 8 being disposed on the outside of the locking block 6, and the bolt 9 being threadedly connected to the inside of the square nut 8 and used to restrict the movement of the limiting plate 7, the installation pipe 5 having a limiting groove 18 on one side corresponding to each limiting plate 7, the other end of the limiting plate 7 being locked into the inside of the limiting groove 18 and used to fix the installation pipe 5.

[0028] Each clip 6 has an external mounting groove 10, and a square nut 8 is snapped into the inside of the mounting groove 10. Each clip 6 has a through hole 11 on the side corresponding to the mounting groove 10. A bolt 9 is threaded into the inside of the square nut 8 through the through hole 11. The connection between the square nut 8 and the mounting groove 10 facilitates the replacement of the square nut 8.

[0029] The outer casing 1 has a storage slot 12 on one side corresponding to each card block 6. The card block 6 is slidably connected inside the storage slot 12. A spring 13 is fixedly connected inside each storage slot 12, and the card block 6 is fixedly connected to the outside of the spring 13.

[0030] Each card block 6 is provided with a fixing block 14 on the outside. The fixing block 14 is L-shaped. Each storage slot 12 has an internal slot 15. The fixing block 14 is snapped into the internal slot 15 and used to limit the position of the card block 6.

[0031] Each locking block 6 has a sliding groove 16 on its outside. The fixing block 14 is slidably connected inside the sliding groove 16 and is used to adjust the position of the locking block 6. A spring 2 17 is fixedly connected inside each sliding groove 16, and the fixing block 14 is fixedly connected to the end of the spring 2 17.

[0032] Rotating ring 3 and annular groove 4: Rotating ring 3 is rotatably connected to annular groove 4 of flange 2, providing the flange 2 with the function of rotation adjustment. When the hole of flange 2 cannot be accurately aligned with the hole of valve and other components, rotating flange 2 can achieve precise alignment, reduce errors and difficulties in the installation process, and improve installation efficiency and accuracy.

[0033] Fixing mechanism and mounting tube 5: One end of the limiting plate 7 is slidably connected to the outside of the clamping block 6, and the other end is clamped in the limiting groove 18 of the mounting tube 5 to restrict the movement of the mounting tube 5 and fix the mounting tube 5.

[0035] Fixed block 14, built-in groove 15 and sliding groove 16: Fixed block 14 works in conjunction with sliding groove 16 and built-in groove 15 to limit the position of locking block 6, prevent locking block 6 from sliding accidentally in non-operation state, and ensure the stability of the fixing mechanism. When bolt 9 cannot be properly disconnected from square nut 8, press fixed block 14 to separate it from built-in groove 15, and locking block 6 can be moved upward. This provides another way to disconnect limit plate 7 from limit groove 18, and increases the flexibility of the device.

[0036] Spring 2 17: After the fixed block 14 slides under the action of external force, spring 2 17 can provide a restoring force to make the fixed block 14 automatically reset, thereby enhancing the stability of the connection between the fixed block 14 and the built-in groove 15.

[0037] Working principle:

[0038] The first step, during the production of water supply pipelines, is to drill holes when connecting new pipelines. If there is still water in the old pipeline, to prevent water leakage, the valve is first sealed to the old pipeline to ensure that the water flow is cut off. Then, the flange 2 is connected to the other end of the valve. If the hole on the flange 2 cannot be aligned with the hole on the valve, the flange 2 can be rotated to align the hole on the flange 2 with the hole on the valve. Then, bolts 9 and other fasteners are used to fasten the flange 2 to the valve to complete the installation. After that, the motor is started and the drill bit can drill holes in the old pipeline through the valve.

[0039] The second step involves rotating bolt 9 to disengage the connection between the square nut 8 and bolt 9. Then, pull the limiting plate 7 to disengage the connection between the limiting plate 7 and the limiting groove 18. Next, pull the mounting tube 5 to disengage the connection between the mounting tube 5 and the outer casing 1. At this point, flange 2 is disassembled. If bolt 9 cannot disengage from the square nut 8, press the fixing block 14 to disengage the connection between the fixing block 14 and the inner groove 15. Then, move the locking block 6 upwards to disengage the connection between the locking block 6 and the limiting plate 7 and the limiting groove 18, thereby releasing the fixed connection between the mounting tube 5 and the outer casing 1 and achieving the disassembly of the mounting tube 5 and flange 2.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
