Description

Technical Field

[0001] The utility model relates to the technical field of pipeline earthquake resistance, in particular to a pipeline earthquake resistance bracket. Background Art

[0002] In the transportation of oil and gas, pipeline transportation has its unique advantages. However, pipeline transportation has very high requirements for pipelines, especially in the event of an earthquake, which can easily lead to pipeline damage. Therefore, how to improve the seismic resistance of pipelines has gradually become a hot topic of research.

[0003] The pipeline seismic support is a device used to provide stable support for the pipeline and protect the pipeline from external forces such as earthquakes. Especially in areas of my country where earthquakes are frequent, the application of pipeline seismic supports is of great significance.

[0004] Pipeline seismic supports can reduce the displacement and acceleration generated during an earthquake, and play a role in stabilizing the pipeline support during an earthquake. Seismic supports can absorb and dissipate seismic energy, reduce the impact of earthquakes on pipeline systems, and reduce the risk of pipeline rupture, thereby reducing losses caused by earthquakes and ensuring the safe operation of pipeline systems. Pipeline seismic supports are not only suitable for pipeline systems in industrial facilities and buildings, but can also be used in pipeline networks of urban water supply, heating, gas, communications and other infrastructure.

[0005] Because earthquakes are divided into transverse waves and longitudinal waves, longitudinal waves are propulsion waves that cause the ground to vibrate up and down, and transverse waves are shear waves that cause the ground to shake horizontally, which are more destructive. Therefore, pipeline seismic supports must not only be able to resist up and down vibrations of the ground, but also be able to resist horizontal shaking of the ground. Existing pipeline seismic supports usually have good resistance to up and down vibrations of the ground, but their ability to resist horizontal shaking of the ground is often insufficient.

[0006] Therefore, the present application provides a pipeline seismic support to overcome the defects of the prior art. Utility Model Content

[0011] As a preferred technical solution, a second fixed block is fixedly connected to the bottom end of the second compression rod, a second connecting rod is fixedly connected to the top of the second fixing block, a second clamping block is fixedly connected to the end of the second connecting rod away from the second fixing block, a second spring is wrapped around the outside of the second connecting rod, the second clamping block in the horizontally arranged second compression rod is located inside the third seismic-resistant tube, and the second clamping block in the vertically arranged second compression rod is located inside the first seismic-resistant tube; the second spring is used to reduce the impact of earthquakes, quickly weaken vibrations, and reduce the length of the second compression rod extending into the seismic-resistant tube during an earthquake, thereby improving the device's resistance to strong earthquakes.

[0012] As a preferred technical solution, blocks are fixedly connected to the inner walls of the first, second and third seismic resistant tubes, and the blocks are used to prevent the first and second clamping blocks from detaching from the seismic resistant tubes.

[0014] The beneficial effects of the utility model are as follows: the utility model provides a seismic support for a pipeline, which can weaken longitudinal waves and reduce the influence of longitudinal waves on the pipeline by arranging the first seismic tube, the second seismic tube, the first telescopic rod, and the second telescopic rod arranged vertically, so that the pipeline can quickly return to a normal state when the ground vibrates vertically;

[0025] The compressible gas refers to a gas whose volume can change with changes in external pressure under certain temperature and pressure. Unlike incompressible gases (such as water vapor), the volume of compressible gas can be compressed. During the compression process, the energy provided externally will be converted into the internal energy of the gas.

[0029] A block 12 is fixedly connected to the inner wall of the first seismic resistant tube 1, the second seismic resistant tube 2 and the third seismic resistant tube 4, and the block 12 is used to prevent the first clamping block 303 and the second clamping block 503 from detaching from the first seismic resistant tube 1, the second seismic resistant tube 2 and the third seismic resistant tube 4.

[0030] Working method: During an earthquake, due to the faster transmission speed of longitudinal waves and the slower transmission speed of transverse waves, the longitudinal waves will reach the ground earlier than the transverse waves, so the pipeline 7 will be affected by the longitudinal waves first and then by the transverse waves. After the longitudinal waves reach the ground, they will cause the ground to vibrate up and down, thereby causing the pipeline 7 to vibrate up and down. At this time, the first telescopic rod 3 and the vertically arranged second telescopic rod 5 reduce the impact of the up and down vibration of the ground by compressing the gas in the first earthquake-resistant tube 1 and the second earthquake-resistant tube 2. At the same time, the springs in the first telescopic rod 3 and the vertically arranged second telescopic rod 5 will also reduce the vibration amplitude of the first earthquake-resistant tube 1 and the second earthquake-resistant tube 2, thereby reducing the impact of the up and down vibration of the ground on the pipeline 7;

[0031] When the shear wave reaches the ground, it will cause the ground to shake horizontally, thereby causing the pipeline 7 to shake horizontally. At this time, the second telescopic rods 5 horizontally arranged on both sides of the pipeline 7 compress the gas in the third seismic resistant tube 4, and convert the kinetic energy of the horizontal shaking of the pipeline 7 into the internal energy of the gas in the third seismic resistant tube 4. At the same time, the second spring 504 in the horizontal second telescopic rod 5 continuously converts the kinetic energy of the horizontal shaking of the pipeline 7 into the elastic potential energy of the spring, further reducing the impact of the earthquake shear wave on the pipeline 7.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should fall within the technical scope of the present invention.
