Description

Technical Field

[0001] This utility model relates to the field of gas pipeline replacement technology, specifically to a quick replacement and installation device for buried gas pipelines. Background Technology

[0002] Buried gas pipelines play a vital role in modern infrastructure construction. However, due to their long-term burial underground environment, they are constantly subjected to various adverse factors such as soil corrosion, geological subsidence, external pressure, and temperature stress. As a result, the probability of pipeline aging, corrosion, and leakage is relatively high. In the event of an emergency gas outage, it will not only cause great inconvenience to residents' daily lives but may also lead to accidents that endanger public safety.

[0003] Traditional methods for replacing and installing buried gas pipelines make it difficult to quickly and accurately position the pipeline to be installed in the maintenance area. This requires manual support and repeated adjustments to the pipeline position during the installation process, wasting a lot of time and manpower. At the same time, when installing emergency repair sections at pipeline joints, manual positioning is usually required, which makes it difficult to place the repair sections accurately at the joints. The operation is also cumbersome, affecting the repair effect and increasing maintenance and time costs. Utility Model Content

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-5 This utility model relates to a quick replacement and installation device for buried gas pipelines, used to connect both ends of the replacement pipeline 1 to the original pipelines 2 on both sides, comprising: The positioning component 3 is detachably mounted on the original pipes 2 on both sides and is used to position the replacement pipe 1.

[0023] In use, first install both ends of the positioning component 3 on the original pipe 2, and position the replacement pipe 1 using the positioning component 3 so that both ends of the replacement pipe 1 are aligned with the original pipe 2. Then, adjust the position of the emergency repair section 4 using the adjustment mechanism 5 until the emergency repair section 4 is connected to the replacement pipe 1 and the original pipe 2. After that, lock the emergency repair section 4 to achieve rapid replacement of the buried gas pipeline and establish a stable connection between the replacement pipe 1 and the original pipe 2.

[0024] Preferably, the emergency repair section 4 is a split joint, which is a common and practical pipe repair accessory. The split joint is usually composed of two semi-annular shells. These two semi-annular shells can be tightly spliced ​​and wrapped around the outside of the pipe. Sealing rubber gaskets are provided inside the two semi-annular shells. At the same time, the split joint is also equipped with multiple bolt and nut assemblies. By tightening the bolts, the two semi-annular shells will gradually approach and tightly fit the outer walls of the replacement pipe 1 and the original pipe 2, realizing a quick connection between the replacement pipe 1 and the original pipe 2.

[0025] In one embodiment, the positioning component 3 includes a support rod 31 horizontally positioned with both ends respectively mounted on the original pipe 2, a vertical rod 32 fixedly mounted at the bottom of the support rod 31, and a clamping member 33 detachably mounted on the replacement pipe 1 at the bottom of the vertical rod 32. This design, by setting the support rod 31 and the vertical rod 32, and providing the clamping member 33 at the bottom of the vertical rod 32, allows for clamping of the replacement pipe 1, thereby achieving positioning of the replacement pipe 1 and facilitating its installation.

[0026] In one embodiment, the clamping member 33 includes a horizontal plate 331 disposed at the bottom end of the vertical rod 32, an arc-shaped support block 332 that conforms to the lower surface of the replacement pipe 1, and a connector 333 for detachably mounting the arc-shaped support block 332 onto the horizontal plate 331. This design, by providing the arc-shaped support block 332 that conforms to the lower surface of the replacement pipe 1, and in conjunction with the connector 333, enables clamping of the replacement pipe 1, thereby achieving positioning of the replacement pipe 1.

[0027] In one embodiment, the connector 333 includes two symmetrically distributed screws 301 threaded through the horizontal plate 331 and a threaded sleeve 302 disposed on the arc-shaped support block 332 for threaded engagement with the screws 301. This design, by configuring the connector 333 to engage with the screws 301 and the threaded sleeve 302, allows for the positioning of the replacement pipe 1 and enables slight adjustment of the height of the replacement pipe 1 according to actual needs, thereby facilitating the alignment of the replacement pipe 1 with the original pipe 2 and facilitating the use of the emergency repair section 4.

[0028] In one embodiment, the inner arc surface of the arc-shaped support block 332 is provided with a plurality of slots 303 evenly distributed. This design, by providing a plurality of slots 303 on the inner arc surface of the arc-shaped support block 332, facilitates the adaptation of the arc-shaped support block 332 to replacement pipes 1 of different sizes, thereby facilitating the use of the arc-shaped support block 332.

[0029] Preferably, the slots 303 are symmetrical to accommodate replacement pipes 1 of different sizes. This design, by setting the slots 303 to a symmetrical structure, facilitates the use of the arc-shaped support block 332.

[0030] In one embodiment, vertical rods 34 are respectively provided at both ends of the support rod 31, and an arc-shaped positioning block 35 is provided at the bottom of the rod 34 and engaged with the original pipe 2. This design, by providing the vertical rods 34 and the arc-shaped positioning block 35, allows the arc-shaped positioning block 35 to be easily adapted to the original pipe 2, thereby achieving the positioning of the rods 34 and the support rod 31 and ensuring the structural stability of the support rod 31.

[0031] Preferably, the bottom of the rod 34 is provided with a connecting part 36 adapted to the arc-shaped positioning block 35. The connecting part 36 includes a base plate 361 located at the bottom of the original pipe 2 and a threaded rod 362 passing through both sides of the base plate 361 and threaded onto the arc-shaped positioning block 35. With this design, by setting the base plate 361 and the threaded rod 362, and the threaded rod 362 being threadedly connected to the arc-shaped positioning block 35, the arc-shaped positioning block 35 can be stably set on the original pipe 2, ensuring the structural stability of the arc-shaped positioning block 35.

[0032] In one embodiment, the adjusting mechanism 5 includes a slide cylinder 51 fixed to the replacement pipe 1, a positioning rod 52 slidably passing through the slide cylinder 51, a stabilizing rod 53 disposed on the emergency repair section 4, and a limiting member 54 disposed on the slide cylinder 51 for limiting the positioning rod 52. The positioning rod 52 is provided with a through hole through which the stabilizing rod 53 passes. This design, by setting the slide cylinder 51, positioning rod 52, stabilizing rod 53, and limiting member 54, allows the positioning rod 52 to slide, thereby driving the emergency repair section 4 to move horizontally, thus achieving the connection between the emergency repair section 4 and the replacement pipe 1 and the original pipe 2.

The positioning rod 52 is provided with a plurality of limiting holes 543 for the limiting rod 541 to pass through. This design, by setting the limiting rod 541 in conjunction with the limiting holes 543 on the positioning rod 52, can limit the position of the positioning rod 52 in the slide cylinder 51. Furthermore, by setting the lifting member 542, the limiting of the positioning rod 52 by the limiting rod 541 can be released as needed, facilitating the adjustment of the position of the emergency repair section 4 by moving the positioning rod 52.

[0034] Preferably, the stabilizing rod 53 is provided with a rod head. This design, by providing a rod head, can limit the positioning rod 52 during use, preventing the connection between the positioning rod 52 and the stabilizing rod 53 from being lost.

[0035] In one embodiment, the lifting member 542 includes a pull plate 501 disposed at the top of the limiting rod 541, and springs 502 are disposed between the two sides of the bottom of the pull plate 501 and the slide cylinder 51. This design allows the limiting rod 541 to release its restriction on the positioning rod 52 by lifting the pull plate 501 upwards, and the springs 502 facilitate the return of the limiting rod 541 to its original position when the pull plate 501 is released.
