Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, specifically relating to a tool for underground pipeline construction. Background Technology

[0002] Buried pipelines transport a wide variety of media, including some hazardous substances such as natural gas and toxic chemicals. For buried gas pipelines, a leak can cause flammable gas to accumulate underground, potentially igniting upon contact with a source of ignition and causing a devastating explosion that could endanger lives and damage buildings. Therefore, the connectors used in buried pipeline construction require high sealing performance. However, some existing connectors are prone to loosening and leaks after prolonged use due to component aging. Utility Model Content

[0003] This utility model provides a buried pipeline construction tool, which has the feature that the connecting sealing wall can always be located outside the connection between the first fixed connecting seat and the second fixed connecting seat to provide a seal. In addition, during long-term use, when the connecting plate accessories age and become loose, the connecting sealing wall can still effectively seal the connection between the first fixed connecting seat and the second fixed connecting seat under the mutual attraction of the first strong magnetic adsorption plate and the second strong magnetic adsorption plate, thus preventing the pipeline from leaking.

[0004] This utility model provides the following technical solution: a buried pipeline construction tool, including a first fixed connecting seat and a second fixed connecting seat. The second fixed connecting seat is located on one side of the first fixed connecting seat. The first fixed connecting seat has a first installation groove inside. An elastic rubber sealing wall is fixedly connected inside the first installation groove, and a connecting sealing wall is fixedly connected to one side of the elastic rubber sealing wall. A first strong magnetic adsorption plate is fixedly connected to the outside of the connecting sealing wall. The second fixed connecting seat has a second installation groove inside, and a second strong magnetic adsorption plate is fixedly connected inside the second installation groove. The first strong magnetic adsorption plate and the second strong magnetic adsorption plate are mutually adsorbed. A connecting plate is fixedly connected to the outside of both the first fixed connecting seat and the second fixed connecting seat, and the connecting plate is used to fix the first fixed connecting seat and the second fixed connecting seat together.

[0005] The outer side of the connecting sealing wall is fixedly connected with a double-layer protective ring, and the double-layer protective ring is located inside the first mounting groove.

[0006] The double-layer protective ring has a third mounting groove inside.

[0007] The third mounting slot has several supporting airbags fixedly connected inside.

[0008] A sealing gasket is fixedly connected to one side of the connecting plate.

[0009] The inner diameter of the second mounting groove is larger than the inner diameter of the first mounting groove.

[0010] The outer side of the double-layer protective ring is fixedly connected with an anti-slip and wear-resistant wall.

[0011] The beneficial effects of this utility model are as follows: Under the traction force of the mutual adsorption between the second strong magnetic adsorption plate and the first strong magnetic adsorption plate, the connecting sealing wall can always be located outside the connection between the first fixed connecting seat and the second fixed connecting seat for sealing. At the same time, through the mutual adsorption of the second strong magnetic adsorption plate and the first strong magnetic adsorption plate, the alignment between the first fixed connecting seat and the second fixed connecting seat can be assisted, so that the first fixed connecting seat and the second fixed connecting seat can be aligned more quickly and accurately, which helps to improve the work efficiency of construction personnel when connecting pipelines. In addition, during long-term use, when the connecting plate accessories age and become loose, the connecting sealing wall can still provide a good seal at the connection between the first fixed connecting seat and the second fixed connecting seat under the mutual adsorption of the first strong magnetic adsorption plate and the second strong magnetic adsorption plate, preventing the pipeline from leaking.

[0018] Please see Figure 1-Figure 4 The present invention provides the following technical solution: a buried pipeline construction tool, including a first fixed connecting seat 1 and a second fixed connecting seat 2. The second fixed connecting seat 2 is located on one side of the first fixed connecting seat 1. The first fixed connecting seat 1 has a first mounting groove 11 inside. An elastic rubber sealing wall 3 is fixedly connected inside the first mounting groove 11, and a connecting sealing wall 4 is fixedly connected to one side of the elastic rubber sealing wall 3. A first strong magnetic adsorption plate 41 is fixedly connected to the outside of the connecting sealing wall 4. The second fixed connecting seat 2 has a second mounting groove 21 inside, and a second strong magnetic adsorption plate 42 is fixedly connected inside the second mounting groove 21. The first strong magnetic adsorption plate 41 and the second strong magnetic adsorption plate 42 are mutually adsorbed. A connecting plate 6 is fixedly connected to the outside of both the first fixed connecting seat 1 and the second fixed connecting seat 2, and the first fixed connecting seat 1 and the second fixed connecting seat 2 are fixed together by the connecting plate 6.

[0019] In this implementation scheme: the first fixed connecting seat 1, in cooperation with the second fixed connecting seat 2, forms the basic framework of the connection and installation tools in the entire pipeline construction. The first installation groove 11 inside the first fixed connecting seat 1 provides a carrier for the connection of the elastic rubber sealing wall 3. The elastic rubber sealing wall 3, in cooperation with the connecting sealing wall 4 and the first strong magnetic adsorption plate 41, forms the sealing element in the entire assembly, used to seal the connection between the two pipelines. The elastic rubber sealing wall 3 also provides the connecting sealing wall 4 with a space for displacement when it moves to one side, preventing the connecting sealing wall 4 from being pulled to one side by the elastic rubber sealing wall 3. When one side moves, motion interference occurs. The second mounting groove 21 inside the second fixed connecting seat 2 provides a carrier for the second strong magnetic adsorption plate 42 to connect. The second strong magnetic adsorption plate 42 is used to adsorb the first strong magnetic adsorption plate 41. When the first fixed connecting seat 1 and the second fixed connecting seat 2 are connected, the second strong magnetic adsorption plate 42 can be adsorbed and fixed by the first strong magnetic adsorption plate 41. When the second strong magnetic adsorption plate 42 adsorbs the first strong magnetic adsorption plate 41, it can pull the connecting sealing wall 4 outward, so that the connecting sealing wall 4 can seal the connection between the first fixed connecting seat 1 and the second fixed connecting seat 2. Under the traction force of mutual adsorption, the connecting sealing wall 4 can always be located outside the connection between the first fixed connecting seat 1 and the second fixed connecting seat 2 to provide a seal. Simultaneously, the mutual adsorption of the second strong magnetic adsorption plate 42 and the first strong magnetic adsorption plate 41 assists in the alignment of the first fixed connecting seat 1 and the second fixed connecting seat 2 during connection, enabling faster and more accurate alignment. This helps improve the work efficiency of construction personnel when connecting pipelines. The connecting plate 6 located outside the first fixed connecting seat 1 and the second fixed connecting seat 2 provides a fastener for the connection between them, especially for buried pipelines. During construction and connection, the first fixed connection seat 1 and the second fixed connection seat 2 are first installed on the connection ends of the pipe. Then, the first fixed connection seat 1 and the second fixed connection seat 2 are assembled. During the assembly of the first fixed connection seat 1 and the second fixed connection seat 2, the first strong magnetic adsorption plate 41 is placed inside the second mounting groove 21. At this time, the second strong magnetic adsorption plate 42 can adsorb the first strong magnetic adsorption plate 41. When the first strong magnetic adsorption plate 41 and the second strong magnetic adsorption plate 42 are attracted to each other, they can pull one side of the connecting sealing wall 4. During the pulling process, the connecting sealing wall 4 can seal the connection between the first fixed connection seat 1 and the second fixed connection seat 2.Finally, the connecting plate 6 completes the installation and fixation between the first fixed connecting seat 1 and the second fixed connecting seat 2. Even if the connecting plate 6 becomes loose due to aging of its components during long-term use, the connecting sealing wall 4 can still effectively seal the connection between the first fixed connecting seat 1 and the second fixed connecting seat 2 under the mutual attraction of the first strong magnetic adsorption plate 41 and the second strong magnetic adsorption plate 42, preventing external leakage of the pipeline.

[0020] A double-layer protective ring 5 is fixedly connected to the outer side of the connecting sealing wall 4, and the double-layer protective ring 5 is located inside the first mounting groove 11. A third mounting groove 51 is opened inside the double-layer protective ring 5, and several supporting airbags 52 are fixedly connected inside the third mounting groove 51. An anti-slip and wear-resistant wall 53 is fixedly connected to the outer side of the double-layer protective ring 5. The third mounting groove 51 is used to provide space for the supporting airbags 52 to be installed. The double-layer protective ring 5 can form a new protection outside the connecting sealing wall 4. At the same time, when the connecting plate 6 becomes loose in a localized manner during long-term use, the supporting airbags 52 can expand outwards, making it easier for staff to quickly find the loose areas on the connecting plate 6 during maintenance.

[0021] A sealing gasket 61 is fixedly connected to one side of the connecting plate 6; the sealing gasket 61 serves to seal.

[0022] The inner diameter of the second mounting groove 21 is larger than the inner diameter of the first mounting groove 11; at this time, the interior of the second mounting groove 21 can provide space for the airbag 52 to expand outward.

[0023] The working principle and usage process of this utility model are as follows: When constructing and connecting buried pipelines, the first fixed connecting seat 1 and the second fixed connecting seat 2 are first installed on the connecting end of the pipeline. Then, the first fixed connecting seat 1 and the second fixed connecting seat 2 are assembled. When assembling the first fixed connecting seat 1 and the second fixed connecting seat 2, the first strong magnetic adsorption plate 41 is placed inside the second mounting groove 21. At this time, the second strong magnetic adsorption plate 42 can adsorb the first strong magnetic adsorption plate 41. When the first strong magnetic adsorption plate 41 and the second strong magnetic adsorption plate 42 are adsorbed to each other, they can pull one side of the connecting sealing wall 4. During the pulling process, the connecting sealing wall 4 can seal the connection between the first fixed connecting seat 1 and the second fixed connecting seat 2. Finally, the installation and fixation between the first fixed connecting seat 1 and the second fixed connecting seat 2 are completed by the connecting plate 6.
