Description

A seismic-resistant pipe support sliding connection node Technical Field

[0001] This utility model relates to the field of pipe support technology, specifically to a seismic-resistant pipe support sliding connection node. Background Technology

[0002] With the acceleration of urbanization and the expansion of industrial facilities, urban underground pipe networks and industrial plant pipeline systems are constantly extending and becoming more complex, covering important fields such as water supply, gas supply, and petrochemicals. These pipeline systems carry key functions such as energy transmission and material transportation. Once damaged, they will trigger a chain reaction. In earthquake-prone areas, pipelines must not only withstand medium pressure and environmental loads, but also resist the violent impact of seismic waves.

[0003] However, traditional seismic-resistant pipe support sliding connection nodes have significant shortcomings. Their structural design often only considers displacement in one or a few directions. When complex seismic waves generate multidimensional vibrations, it is difficult to achieve free sliding of the pipe in all directions. This limitation will cause excessive stress concentration in a certain direction. Even if the support can partially alleviate the vibration, it is difficult to avoid the pipe from cracking, disintegrating or severely deforming due to local stress exceeding its bearing limit. At the same time, traditional nodes are difficult to buffer and limit the sliding components during the sliding process. Excessive displacement may cause the pipe to collide with other adjacent facilities, reducing the stability of the pipeline system in earthquakes. Therefore, there is an urgent need for a seismic-resistant pipe support sliding connection node to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a seismic-resistant pipe support sliding connection node to solve the problem mentioned in the background art that when an earthquake occurs, the traditional seismic-resistant pipe support sliding connection node is difficult to move in all directions according to the magnitude of the earthquake, which may easily lead to excessive force in one direction, resulting in pipe rupture, disconnection or deformation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant pipe support sliding connection node, including a fixing plate, wherein a supporting sliding component is provided on the top surface of the fixing plate;

[0006] The supporting sliding assembly includes a limiting plate, which is fixedly connected to the top surface of the fixed plate. A sliding groove is provided at the upper end of the limiting plate. A support frame is slidably connected to the inner wall of the sliding groove. A limiting groove is provided on the bottom surface of the support frame. A plurality of rotating balls are provided on the inner wall of the limiting groove, and the plurality of rotating balls abut against the inner wall of the sliding groove.

[0007] Preferably, a limiting ring is provided on the inner wall of the sliding groove, and a plurality of compression springs are fixedly connected to the surface of the limiting ring, and the plurality of compression springs are fixedly connected to the inner wall of the sliding groove.

[0008] Preferably, the top surface of the support frame is provided with multiple fixing holes, and the inner walls of two of the fixing holes are detachably connected to fixing clamps by bolts.

[0009] Preferably, a wear-resistant ring is fixedly connected to the inner wall of the limiting ring, and the size of the wear-resistant ring matches the size of the limiting ring.

[0010] Preferably, the bottom surface of the fixing plate is provided with a fixing groove, and an anti-slip pad is fixedly connected to the inner wall of the fixing groove.

[0011] Preferably, the side wall of the support frame has two weight-reduction holes, and the two weight-reduction holes are of the same size.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using a sliding support assembly, the pipeline is secured to the support frame via two fixed clamps. When an earthquake causes the pipeline to move, the support frame slides in all directions with the amplitude of the vibration, thanks to the cooperation of multiple rotating balls. This prevents the pipeline from rupturing, disintegrating, or deforming due to excessive force in one direction, effectively maintaining the continuity and integrity of the pipeline system and reducing accidents such as leaks and breaks caused by pipeline damage. At the same time, the use of limit rings, wear-resistant rings, and multiple compression springs facilitates the buffering and limiting of the sliding of the support frame. This absorbs and dissipates seismic energy while preventing excessive displacement that could cause the pipeline to collide with other adjacent facilities, ensuring the stability of the pipeline system during earthquakes.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4. This utility model provides a sliding connection node for an anti-seismic pipe support, including a fixed plate 1. A supporting sliding assembly 2 is provided on the top surface of the fixed plate 1. The supporting sliding assembly 2 includes a limiting plate 201, which is fixedly connected to the top surface of the fixed plate 1. A sliding groove 202 is formed at the upper end of the limiting plate 201. A support frame 203 is slidably connected to the inner wall of the sliding groove 202. A limiting groove 204 is formed on the bottom surface of the support frame 203, and multiple rotating balls 20 are provided on the inner wall of the limiting groove 204. 5. Multiple rotating balls 205 abut against the inner wall of the sliding groove 202. Through the set support sliding component 2, the pipeline is fixed to the support frame 203 by two fixed clamps 210. When an earthquake causes the pipeline to move, the support frame 203 slides in all directions with the amplitude of the vibration under the cooperation of multiple rotating balls 205, thereby avoiding pipeline rupture, disconnection or deformation due to excessive force in one direction, effectively maintaining the continuity and integrity of the pipeline system, and reducing accidents such as leakage and breakage caused by pipeline damage.

[0021] Furthermore, a limiting ring 206 is provided on the inner wall of the sliding groove 202. Multiple compression springs 207 are fixedly connected to the surface of the limiting ring 206. All compression springs 207 are fixedly connected to the inner wall of the sliding groove 202. Through the cooperation of the limiting ring 206 and the multiple compression springs 207, it is convenient to buffer and limit the sliding of the support frame 203. This absorbs and dissipates seismic energy while avoiding excessive displacement that may cause the pipeline to collide with other adjacent facilities, thus ensuring the stability of the pipeline system during an earthquake.

[0022] Furthermore, the top surface of the support frame 203 is provided with multiple fixing holes 209. The inner walls of two fixing holes 209 are detachably connected to fixing clamps 210 by bolts. The fixing holes 209 and fixing clamps 210 facilitate the fixing of the pipe to the support frame 203.

[0023] Furthermore, a wear-resistant ring 208 is fixedly connected to the inner wall of the limiting ring 206. The size of the wear-resistant ring 208 matches the size of the limiting ring 206. The wear-resistant ring 208 facilitates the protection of the limiting ring 206 and improves its service life.

[0024] Furthermore, a fixing groove 211 is provided on the bottom surface of the fixing plate 1, and an anti-slip pad 212 is fixedly connected to the inner wall of the fixing groove 211. The anti-slip pad 212 facilitates the increase of friction between the fixing plate 1 and the ground.

[0025] Furthermore, the side wall of the support frame 203 has two weight-reduction holes 213. The two weight-reduction holes 213 are matched in size. By setting the two weight-reduction holes 213, it is easy to reduce the overall weight of the support frame 203 without affecting its performance, thus saving processing materials.

[0026] Working principle: The pipeline is fixed to the support frame 203 by the set support sliding component 2 through two fixed clamps 210. When an earthquake causes the pipeline to move, the support frame 203 slides in all directions with the amplitude of the vibration under the cooperation of multiple rotating balls 205, thereby avoiding pipeline rupture, disconnection or deformation due to excessive force in one direction. This effectively maintains the continuity and integrity of the pipeline system and reduces accidents such as leakage and breakage caused by pipeline damage. At the same time, the cooperation of the set limit ring 206, wear-resistant ring 208 and multiple compression springs 207 makes it easy to buffer and limit the sliding of the support frame 203, thereby absorbing and dissipating seismic energy while avoiding excessive displacement that may cause the pipeline to collide with other adjacent facilities, ensuring the stability of the pipeline system during earthquakes.
