Description

Technical Field

[0001] The utility model relates to the technical field of plugging devices, in particular to a pipeline plugging device. Background Art

[0002] A pipeline is a device connected by pipes, pipe fittings and valves for transporting gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations.

[0003] The existing method of sealing the cable pipeline is generally to use a cable plug to seal the pipeline. When using the cable plug, it needs to be divided into two parts first, so that the rubber inside it is divided into two parts, and then the two semicircular cable plugs are attached to the surface of the cable and squeezed toward the middle of the cable plug, and then the cable plug wrapped on the surface of the cable is inserted into the pipeline. Since the cable plug is filled with rubber material between two iron sheets, when the cable plug is inserted into the pipeline, the friction between the rubber material and the inner wall of the pipeline makes it necessary to use an external tool to hammer the pipeline sealer into the pipeline, and then it is necessary to use a wrench to tighten the screw nut on the pipeline sealer. At the same time, the pipeline sealer is flush with one end of the pipeline in the pipeline, which makes it difficult to disassemble the pipeline sealer. Its installation and disassembly are time-consuming and labor-intensive, and it reduces the sealing efficiency of the pipeline plugger to the pipeline. Therefore, a pipeline plugger is proposed to solve the above problems. Utility Model Content

[0021] Reference Figure 1-6 A pipeline plugging device comprises a pipeline assembly, which comprises a pipeline body 1 and a cable 101. A mounting block 2 is arranged at one end of the pipeline body 1, a mounting groove is provided at one end of the mounting block 2, a clamping assembly is arranged in the mounting groove, the clamping assembly comprises a bidirectional screw 3 rotatably connected in the mounting groove, a nut block 301 is threadedly connected to a surface of the bidirectional screw 3, an L-shaped connecting rod 6 is fixedly connected to one end of the nut block 301, a handle 302 is fixedly connected to the surface of the bidirectional screw 3 (the bidirectional screw 3 is driven to rotate by the handle 302, so that the nut block 301 drives the arc ring 4 to move and clamp on the surface of the pipeline body 1, so as to realize the installation of the device), a connecting block 5 is arranged above the mounting block 2, a sliding groove is provided at one end of the connecting block 5 which is slidably connected to the L-shaped connecting rod 6, an arc ring 4 is fixedly connected to one end of the L-shaped connecting rod 6, and a rubber block 401 is arranged on the inner wall of the arc ring 4 (the rubber block 401 can further increase the friction between the arc ring 4 and the pipeline, thereby increasing the stability of the device installed on the pipeline);

[0022] A plugging component is provided in the pipeline body 1 (the plugging component seals the pipeline body 1), and the plugging component includes a front semicircular sealing ring 7 (the contact surfaces of the two front semicircular sealing rings 7 are provided with sealing rings) and a rear semicircular sealing ring 703 (the contact surfaces of the two rear semicircular sealing rings 703 are provided with sealing rings) which are located in the pipeline and are relatively arranged. One end of the connecting block 5 is fixedly connected to one end of the front semicircular sealing ring 7, and a movable groove is provided at one end of the mounting block 2. One end of the front semicircular sealing ring 7 is fixedly connected to an L-shaped sliding block 701 which is slidably connected to the movable groove.

[0023] Furthermore, a circular tube 801 is provided at one end of the front semicircular sealing ring 7 and the rear semicircular sealing ring 703. The circular tube 801 on the front semicircular sealing ring 7 is hollow, and an airbag 8 is connected between the circular tube 801 on the front semicircular sealing ring 7 and the circular tube 801 on the rear semicircular sealing ring 703 (the airbag 8 is inflated to seal the inside of the pipeline).

[0024] It should be noted that the circular tube 801 located on the front semicircular sealing ring 7 is connected to the interior of the airbag 8 and penetrates the front semicircular sealing ring 7. The interiors of the two front semicircular sealing rings 7 are provided with connected air grooves, and the air grooves on the two front semicircular sealing rings 7 are connected to the two circular tubes 801.

[0025] It is worth noting that: an air pipe 702 penetrating the front semicircular sealing ring 7 and communicating with the air groove is provided at one end of one of the front semicircular sealing rings 7 , and a valve is provided on the air pipe 702 .

[0026] A further advantage of adopting the above is that the above device does not need to be installed or disassembled with the aid of other tools, making installation and disassembly relatively simple, which saves time and effort while improving the plugging efficiency of the pipeline plugger on the pipeline body 1.

[0027] When the utility model is in use: when it is necessary to seal the cable 101 pipeline, the staff takes the device to the pipeline body 1 that needs to be sealed, and then the staff moves the two front semicircular sealing rings 7 and the two rear semicircular sealing rings 703 toward the middle, so that the front semicircular sealing rings 7 and the rear semicircular sealing rings 703 are wrapped around the surface of the cable 101, and then the staff inserts the front semicircular sealing rings 7 and the rear semicircular sealing rings 703 into the pipeline body 1, and then the staff holds the handle 302 and rotates it, and the rotation of the handle 302 drives the bidirectional screw 3 to rotate, so that the two nut blocks 301 move toward the middle, and the movement of the nut block 301 drives the two L-shaped connecting rods 6 and the two arc rings 4 to move, and the staff can tightly wrap the two arc rings 4 and the rubber block 401 around the surface of the pipeline body 1 by rotating the handle 302;

[0028] Then the staff connects the air pump to the air pipe 702 and opens the valve, pumps air into the air pipe 702 through the air pump, and enters the inside of the air groove, and enters the inside of the two air bags 8 through the air groove and the round tube 801, so that the air bags 8 expand and block the inside of the pipeline body 1, and then the staff closes the valve;

[0029] When the device needs to be disassembled, the staff opens the valve to allow the gas inside the airbag 8 to be discharged through the trachea 702, causing the airbag 8 to slowly deflate and lose its seal on the pipeline body 1. The staff then turns the handle 302 to move the arc ring 4 and the rubber block 401 to both sides and separate them from the pipeline body 1. The staff then uses the mounting block 2 and the L-shaped connecting rod 6 to remove the front semicircular sealing ring 7 and the airbag 8 as well as the rear semicircular sealing ring 703 from the pipeline body 1 through the interface. The above-mentioned device does not require the aid of other tools to be installed and disassembled, making installation and disassembly relatively simple. It saves time and effort while improving the sealing efficiency of the pipeline plugger on the pipeline body 1.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
