Description

Technical Field

[0001] The utility model belongs to the technical field of anti-settlement devices, and particularly relates to an anti-settlement device for gas pipelines. Background Technique

[0002] In the construction of modern urban infrastructure, gas pipelines, as an important artery for energy transmission, their safety and stability are directly related to the quality of life of urban residents and public safety. Especially against the backdrop of the accelerating urbanization process, the gas pipeline network is becoming increasingly complex, and it has become normal to cross various terrains and landforms. Among them, the crossing of natural obstacles such as rivers and ditches is particularly crucial.

[0003] Traditionally, when gas pipelines cross areas such as rivers and ditches, they are mostly laid along road bridges and culverts. Although this method can effectively avoid the ecological damage and construction difficulties caused by directly excavating rivers or ditches, it also brings new challenges, such as the problem of uneven settlement between the bridge and culvert and the road surface. Since the bridge and culvert structure usually uses more solid materials and special construction methods, its foundation stability is relatively high, while the road surface may be affected by various factors such as geological conditions, traffic loads, and hydrological changes, resulting in different degrees of settlement. Under the long-term action of this uneven settlement phenomenon, it will produce a huge stress concentration effect on the gas pipeline passing through it, leading to pipeline bending, deformation, or even rupture, seriously affecting the safety of gas transportation and the service life of the pipeline. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-settlement device for gas pipelines to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-settlement device for gas pipelines, comprising:

[0007] A bottom plate, on the top of which a pipeline installer is movably installed, and a gas pipeline is movably installed inside the pipeline installer;

[0008] A buffer assembly, which is arranged on one side of the bottom plate. The buffer assembly includes a bracket fixedly installed on the top of the bottom plate. A pillar is movably installed inside the bracket. A first spring is connected between the pillar and the bracket. Adjusting blocks are movably installed on both sides of the bracket. Buffer blocks are fixedly connected to both sides of the pillar. A push rod is movably connected between the buffer block and the adjusting block. A second spring is connected to one side of the adjusting block;

[0009] Disassembly and assembly component, the disassembly and assembly component is arranged on one side of the top of the support column. The disassembly and assembly component includes a C-shaped frame fixedly installed at the top of the support column. A T-shaped block is movably installed inside the C-shaped frame. One side of the T-shaped block is fixedly connected to the pipeline installer. Locking holes are opened on both sides of the T-shaped block. Locking rods are movably installed on both sides of the C-shaped frame.

[0010] Preferably, a support is fixedly installed at the center of the top of the bottom plate. A support column is movably installed inside the support. The support column is in sliding fit with the inner wall of the support. A first spring is connected between the support column and the inner wall of the support. Limiting grooves are symmetrically opened on both sides of the support. Limiting blocks are movably installed inside the limiting grooves. The limiting blocks are in sliding fit with the inner walls of the limiting grooves. One side of the limiting block close to the inside of the support is fixedly connected to the support column.

[0011] Preferably, adjusting frames are symmetrically installed on both sides of the support. A sliding rod is fixedly installed inside the adjusting frame. An adjusting block is movably sleeved outside the sliding rod. The adjusting block is in sliding fit with the inner wall of the adjusting frame. A second spring is connected between the adjusting block and the inner wall of the adjusting frame. The second spring is arranged outside the sliding rod.

[0012] Preferably, buffer grooves are symmetrically opened on both sides of the support. Buffer blocks are movably installed inside the buffer grooves. The buffer blocks are fixedly connected to the support column. A push rod is hinged between the buffer blocks and the adjusting blocks.

[0013] Preferably, U-shaped plates are symmetrically installed on both sides of the top of the C-shaped frame. A baffle is fixedly installed inside the U-shaped plates. A locking rod is movably installed between the baffle and the U-shaped plates through an opening. One end of the locking rod penetrates into the inside of the C-shaped frame. One end of the locking rod extends into the locking hole.

[0014] Preferably, a reset plate is fixedly installed on the outside of the locking rod. Two reset springs are connected between the reset plate and the inner wall of the U-shaped plate. The two reset springs are symmetrically arranged on both sides of the locking rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1) By arranging the first spring between the support column and the support, and at the same time connecting the second spring between the adjusting block and the inner wall of the adjusting frame, through the buffering effects of the first spring and the second spring, the stress generated by the uneven settlement between the bridge culvert and the road ground can be effectively absorbed and relieved. When the gas pipeline is affected by the settlement, the support column will automatically adjust its position under the action of the first spring and the second spring, so that the gas pipeline can sink a certain distance accordingly, thereby maintaining the straight state of the gas pipeline, preventing bending and deformation. This self-adaptive adjustment mechanism can significantly improve the anti-settlement ability of the gas pipeline and extend the service life of the gas pipeline.

[0017] (2) The utility model realizes the disassembly and assembly between the pipeline installer and the bracket through the cooperation of the C-shaped frame and the T-shaped block, and the cooperation of the locking rod and the locking hole can lock the T-shaped block to ensure the stability of the pipeline installer. This rapid disassembly and assembly structure design makes the replacement of the pipeline installer simple and fast. When the pipeline installer is damaged due to long-term use, there is no need to disassemble the entire bracket structure, and only a new pipeline installer needs to be replaced. This design not only improves the maintenance efficiency but also reduces the maintenance cost. At the same time, since the frequent maintenance work due to pipeline damage is reduced, the cost-effectiveness of the entire gas pipeline system is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figure 1 - Figure 3 as shown, a gas pipeline anti-settlement device includes:

[0027] The bottom plate 1 has a pipe installer 11 movably installed at the top end thereof, and a gas pipe 12 is movably installed inside the pipe installer 11;

[0028] The buffer assembly 2 is arranged on one side of the bottom plate 1. The buffer assembly 2 includes a bracket 21 fixedly installed at the top end of the bottom plate 1. A pillar 22 is movably installed inside the bracket 21. A first spring 23 is connected between the pillar 22 and the bracket 21. Adjusting blocks 28 are movably installed on both sides of the bracket 21. Buffer blocks 211 are fixedly connected to both sides of the pillar 22. A push rod 212 is movably connected between the buffer block 211 and the adjusting block 28. A second spring 29 is connected to one side of the adjusting block 28;

[0029] The disassembly and assembly component 3 is arranged on one side of the top end of the pillar 22. The disassembly and assembly component 3 includes a C-shaped frame 31 fixedly installed at the top end of the pillar 22. A T-shaped block 32 is movably installed inside the C-shaped frame 31. One side of the T-shaped block 32 is fixedly connected to the pipe installer 11. Locking holes 33 are formed on both sides of the T-shaped block 32. Locking rods 36 are movably installed on both sides of the C-shaped frame 31.

[0030] Specifically, a bracket 21 is fixedly installed at the center of the top end of the bottom plate 1. A pillar 22 is movably installed inside the bracket 21. The pillar 22 is in sliding fit with the inner wall of the bracket 21. A first spring 23 is connected between the pillar 22 and the inner wall of the bracket 21. Limiting grooves 24 are symmetrically formed on both sides of the bracket 21. Limiting blocks 25 are movably installed inside the limiting grooves 24. The limiting blocks 25 are in sliding fit with the inner walls of the limiting grooves 24. The limiting blocks 25 are fixedly connected to the pillar 22 on the side close to the inside of the bracket 21.

[0031] As can be seen from the above, the first spring 23 can provide a certain buffering ability for the pillar 22, and the limiting grooves 24 and the limiting blocks 25 can limit the pillar 22 to prevent it from disengaging from the inside of the bracket 21.

[0032] Specifically, adjusting frames 26 are symmetrically installed on both sides of the bracket 21. A sliding rod 27 is fixedly installed inside the adjusting frame 26. An adjusting block 28 is movably sleeved on the outer side of the sliding rod 27. The adjusting block 28 is in sliding fit with the inner wall of the adjusting frame 26. A second spring 29 is connected between the adjusting block 28 and the inner wall of the adjusting frame 26. The second spring 29 is arranged on the outer side of the sliding rod 27. Buffer grooves 210 are symmetrically formed on both sides of the bracket 21. Buffer blocks 211 are movably installed inside the buffer grooves 210. The buffer blocks 211 are fixedly connected to the pillar 22. A push rod 212 is hinged between the buffer block 211 and the adjusting block 28.

[0033] As can be seen from the above, the sliding rod 27 provides a limiting function for the adjusting block 28. The second spring 29, in cooperation with the adjusting block 28, the buffer block 211, and the push rod 212, can enhance the anti-settlement ability of the device. When the support column 22 descends, it will also drive the adjusting block 28 to move through the push rod 212, thereby causing the second spring 29 to be stressed, forming a dual buffer system. When the gas pipeline 12 descends due to settlement, the settlement energy can be further dispersed and absorbed, improving the stability and reliability of the device.

[0034] Embodiment 2:

[0035] Please refer to Figure 1 and Figure 4 - Figure 5 As shown in the figure, U-shaped plates 34 are symmetrically installed on both sides of the top end of the C-shaped frame 31. A baffle 35 is fixedly installed inside the U-shaped plate 34. A locking rod 36 is movably installed between the baffle 35 and the U-shaped plate 34 through an opening. One end of the locking rod 36 penetrates into the inside of the C-shaped frame 31, and one end of the locking rod 36 extends into the locking hole 33.

[0036] Specifically, a reset plate 37 is fixedly installed on the outer side of the locking rod 36. Two reset springs 38 are connected between the reset plate 37 and the inner wall of the U-shaped plate 34. The two reset springs 38 are symmetrically arranged on both sides of the locking rod 36.

[0037] As can be seen from the above, the locking rod 36 cooperates with the locking hole 33 to fix the T-shaped block 32. The reset spring 38, in cooperation with the reset plate 37, can drive the locking rod 36 to complete the reset, improving the disassembly and assembly efficiency.

[0038] This application can be applied to the expansion project of the urban gas pipeline 12. For example, during the expansion, there is a laying task of a gas pipeline 12 that needs to cross a main river. The road foundations on both sides of the river are significantly different. Historical data shows that due to different geological conditions and traffic loads on both sides of the road, there is an obvious uneven settlement phenomenon. To ensure the safety and stability of the gas pipeline 12 when crossing the river and reduce the risk of pipeline damage caused by settlement in the future, the project team decided to use this device to lay the gas pipeline 12. The specific implementation steps are as follows:

[0039] S1. The project team first conducts a detailed survey of the road foundations on both sides of the river, including the collection and analysis of information such as geological conditions, soil properties, and historical settlement data. Based on the survey results and combined with the design requirements of the gas pipeline 12, a detailed construction plan is formulated, including the installation location, quantity, size, and specific configuration of this device;

[0040] S2. After the installation of this device is completed, the laying work of the gas pipeline 12 is started. The gas pipeline 12 is laid above the bridge culvert according to the design requirements, and it is ensured that the connection between the gas pipeline 12 and the pipeline installer 11 is tight;

[0041] S3. After completing all installation work, organize relevant departments and experts to accept the installed gas pipeline 12 and this device to ensure that all performance indicators meet the design requirements and safety standards;

[0042] S4. When subsequent maintenance or replacement of the pipe installer 11 is required, first disconnect the connection between the pipe installer 11 and the gas pipeline 12, then pull the locking rods 36 on both sides to move the locking rods 36 away from the locking holes 33, then extract the T-shaped block 32, put in a new T-shaped block 32, then release the locking rods 36, and the locking rods 36 will extend into the locking holes 33 under the action of the return spring 38 to complete the installation. Finally, connect the pipe installer 11 and the gas pipeline 12;

[0043] S5. Regularly inspect and maintain this device and the gas pipeline 12 to ensure that they are in good working condition.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
