Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a pipeline fixing device for municipal gas engineering. Background Technology

[0002] Municipal gas engineering refers to the engineering and technical system that supplies gas to urban users in a centralized manner to meet their heat energy needs. This project includes gas source points such as gas source stations or stations receiving gas from upstream pipelines, and transports gas that meets quality requirements to urban gas users through pipelines, with functions of gas transmission, distribution, storage, and certain peak-shaving.

[0003] In municipal gas engineering, it is necessary to lay gas pipelines. During pipeline construction, fixing devices are needed to support and fix the pipelines. These devices not only bear the weight of the pipelines but also fix them in the predetermined positions to prevent displacement or vibration due to external forces or their own weight. Pipe supports are commonly used for support and fixation to keep the pipelines stable and safe.

[0004] Traditional pipe support structures only provide support and fixation. When the pipeline is transporting gas and the flow speed exceeds a certain limit, aerodynamic phenomena will occur, causing unstable gas pressure inside the pipeline. This can easily lead to pipeline vibration, which will increase the friction between the pipe support and the pipeline. Over time, this will cause the surface of the pipe support to wear more quickly, thus affecting its service life. Utility Model Content

[0005] The purpose of this utility model is to provide a pipeline fixing device for municipal gas engineering, addressing the defects and shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline fixing device for municipal gas engineering, comprising a pipe support base, a lower support hoop disposed at the upper end of the pipe support base, an upper support hoop disposed at the upper end of the lower support hoop, a connecting mechanism disposed between the lower support hoop and the upper support hoop for fixing the lower support hoop and the upper support hoop to support and fix the pipeline, and further comprising a plurality of support buffer groups annularly disposed on the lower support hoop and the upper support hoop for supporting and fixing the pipeline when the lower support hoop and the upper support hoop are fixed, and for buffering vibration when the pipeline vibrates; The support and buffer assembly includes two support blocks symmetrically arranged on the lower or upper support hoop for supporting and fixing the pipeline, a buffer sphere disposed between the two support blocks for elastically supporting the pipeline and providing initial buffering when the pipeline vibrates, and a buffer connector disposed on the buffer sphere and the lower or upper support hoop for generating elastic deformation to improve the buffering effect when the pipeline vibration is transmitted to the buffer sphere for initial buffering.

[0007] A further improvement is that the support block is a nylon block.

[0008] A further improvement is that the buffer sphere is a rubber sphere, a silicone sphere, or a plastic sphere.

[0009] A further improvement is that the buffer connector is an elastic connector, and there are two buffer connectors, which are symmetrically arranged on the buffer ball and the lower support hoop or the upper support hoop, either left and right or front and back.

[0010] A further improvement is that a plastic connecting block is provided between the elastic connector and the lower or upper support hoop.

[0011] A further improvement is that each of the two buffer connectors is provided with an arc-shaped deformation section.

[0012] A further improvement is that a buffer groove is formed on the buffer sphere in a ring shape.

[0013] A further improvement is that the connecting mechanism includes two connecting screws disposed on the lower support hoop, two connecting through holes opened on the upper support hoop for clearance fit with the connecting screws, and two connecting nuts respectively threaded onto the two connecting screws.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the upper support hoop and the lower support hoop are wrapped and connected to the outer surface of the pipe, and then the lower support hoop and the upper support hoop are fixed by the connecting mechanism. After fixing, the pipe is supported and fixed by two support blocks in each support buffer group, which restricts the vertical and horizontal displacement of the pipe. As the connecting mechanism fixes the lower support hoop and the upper support hoop, the outer wall of the pipe presses each buffer ball inward. When the gas pressure inside the pipe is unstable and causes the pipe to vibrate, the vibration is initially buffered by the buffer ball. Part of the impact force generated by the vibration is transmitted to the buffer connector. The buffer connector generates elastic deformation to improve the buffering effect. The vibration is buffered by the double-layer buffer structure, reducing the friction between the pipe vibration and the pipe support, thereby reducing the wear on the surface of the pipe support and reducing the impact on the service life of the pipe support.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] See Figures 1 to 3 As shown, the technical solution adopted in this specific embodiment is: a pipeline fixing device for municipal gas engineering, including a pipe support base 1, a lower support clamp 2 disposed at the upper end of the pipe support base 1, an upper support clamp 3 disposed at the upper end of the lower support clamp 2, a connecting mechanism disposed between the lower support clamp 2 and the upper support clamp 3 for fixing the lower support clamp 2 and the upper support clamp 3 to support and fix the pipeline, and further including a plurality of support buffer groups annularly disposed on the lower support clamp 2 and the upper support clamp 3 for supporting and fixing the pipeline when the lower support clamp 2 and the upper support clamp 3 are fixed, and for buffering vibration when the pipeline vibrates; The support and buffer assembly includes two support blocks 4 symmetrically arranged on the lower support hoop 2 or the upper support hoop 3 for supporting and fixing the pipeline, a buffer ball 5 arranged between the two support blocks 4 for elastically supporting the pipeline and providing initial buffering when the pipeline vibrates, and a buffer connector 6 arranged on the buffer ball 5 and the lower support hoop 2 or the upper support hoop 3 for generating elastic deformation to improve the buffering effect when the pipeline vibration is transmitted to the buffer ball 5 for initial buffering.

[0020] Several support buffer groups are equidistantly arranged in a ring on both the lower support clamp 2 and the upper support clamp 3. The number of support buffer groups can be five equidistantly arranged in a ring on each of the lower and upper support clamps 2 and 3 respectively. Each support buffer group includes two support blocks 4, a buffer ball 5, a buffer connector 6, and a plastic connector 7. The buffer connector 6 is fixed between the buffer ball 5 and the plastic connector 7 by adhesive or heat fusion. A space is formed between the two support blocks 4, which is used for the installation and connection of the buffer ball 5, the buffer connector 6, and the plastic connector 7, and provides inward movement space for the buffer ball 5 and deformation space for the buffer connector 6. The connection mechanism is the existing pipe support connecting screw 10 and connecting nut 12 for the lower support clamp 2 and the upper support clamp 3. The lower support clamp 2 and the upper support clamp 3 are pressed together by the threaded connection of the connecting screw 10 and the connecting nut 12, thereby wrapping and squeezing against the outer wall of the pipe.

[0021] The support block 4 is a nylon block. It is a solid block and is installed on the lower support hoop 2 and upper support hoop 3 using adhesive or hot-melt methods. The nylon block absorbs impact and provides protection. The elasticity of the nylon material allows these components to reduce vibration and impact when the equipment is subjected to shocks, effectively reducing damage and maintenance costs. The nylon support block 4 is used to support and fix components in mechanical equipment, ensuring stable operation. Furthermore, nylon material has excellent wear resistance and impact resistance.

[0022] Nylon blocks, in particular, exhibit better wear resistance than steel, enabling them to withstand prolonged use in high-friction environments without significant wear. Through their supporting and fixing properties, as well as their impact absorption and wear resistance, they can provide slight cushioning while simultaneously supporting and securing pipes, reducing vibration transmission to the pipe supports. The buffer sphere 5 is a rubber sphere, a silicone sphere, or a plastic sphere.

[0023] The buffer sphere 5 is made of rubber, silicone, or plastic material. Under the condition of elastic buffering, the buffer sphere 5 can transmit the remaining vibration to the buffer connector 6 when it is subjected to pipeline vibration. Compared with flexible materials such as sponge, EVA, or foam, it can effectively transmit vibration to the buffer connector 6 and play a preliminary buffering role.

[0024] The buffer connector 6 is an elastic connector. There are two buffer connectors. The two buffer connectors 6 are symmetrically arranged on the buffer ball 5 and the lower support hoop 2 or the upper support hoop 3, either left and right or front and back.

[0025] A plastic connecting block 7 is provided between the elastic connector and the lower support hoop 2 or the upper support hoop 3. The plastic connecting block 7 is fixed to the lower support hoop 2 and the upper support hoop 3 by adhesive and is located between the two support blocks 4. The plastic material has a significant cushioning effect and can effectively absorb impact force.

[0026] Among them, the plastic connecting block 7 can buffer the remaining vibration after the elastic connector is buffered, thereby reducing the vibration transmitted to the lower support hoop 2 or the upper support hoop 3 and reducing the impact of vibration on the lower support hoop 2 or the upper support hoop 3.

[0027] Each of the two buffer connectors 6 is provided with an arc-shaped deformation portion 8. The arc-shaped deformation portion 8 provided on the two buffer connectors 6 creates a space between the two buffer connectors 6 that deforms in opposite directions.

[0028] In this configuration, when the pipeline compresses the buffer ball 5, the buffer ball 5 moves inward and compresses the two buffer connectors 6. The arc-shaped deformation part 8 allows the two buffer connectors 6 to undergo elastic deformation in opposite directions. Furthermore, when vibration impacts the buffer ball 5, the two elastically deformed buffer connectors 6 still have deformation space, thereby improving the buffering effect against vibration impact.

[0029] The buffer sphere 5 is provided with a buffer groove 9 in an annular shape. The buffer groove 9 can increase the compression space of the buffer sphere 5 when the pipeline vibrates, making it easier for the buffer sphere 5 to generate elastic deformation inward, thereby improving the buffering effect of the buffer sphere 5 on vibration impact.

[0030] The connecting mechanism includes two connecting screws 10 disposed on the lower support hoop 2, two connecting holes 11 through the upper support hoop 3 for clearance fit with the connecting screws 10, and two connecting nuts 12 respectively threaded onto the two connecting screws 10.

[0031] Two connecting screws 10 are respectively welded to the left and right ends of the lower support hoop 2. Connecting through holes 11 are respectively opened at the left and right ends of the upper support hoop 3. When the lower support hoop 2 and the upper support hoop 3 are aligned so that their inner rings form a circle, the connecting screws 10 and the connecting through holes 11 are fully engaged. Then, the connecting nut 12 is screwed onto the connecting screws 10 for fixation. The diameter of the connecting through hole 11 is smaller than the diameter of the connecting nut 12.

[0032] The working principle of this utility model is as follows: The upper support hoop 3 and the lower support hoop 2 are wrapped and connected to the outer surface of the pipe. Then, the lower support hoop 2 and the upper support hoop 3 are fixed by the connecting mechanism. After fixing, the pipe is supported and fixed by two support blocks 4 in each support buffer group, which restricts the vertical and horizontal displacement of the pipe. As the connecting mechanism fixes the lower support hoop 2 and the upper support hoop 3, the outer wall of the pipe presses each buffer ball 5 to move inward. When the gas pressure inside the pipe is unstable and causes the pipe to vibrate, the vibration is initially buffered by the buffer ball 5. Part of the impact force generated by the vibration is transmitted to the buffer connector 6. The buffer connector 6 generates elastic deformation to improve the buffering effect. The vibration is buffered by the double-layer buffer structure, which reduces the friction between the pipe vibration and the pipe support, thereby reducing the wear on the surface of the pipe support and reducing the impact on the service life of the pipe support.
