Abstract
Description
Technical Field
[0001] This utility model relates to the field of natural gas pipeline technology, and in particular to an adjustable seismic support device for natural gas pipelines. Background Technology
[0002] Natural gas pipeline support devices are an indispensable part of natural gas pipeline systems, used to support, fix, and protect pipelines to ensure their safe and stable operation.
[0003] Traditional natural gas pipeline support components have a simple structure and are not very effective at isolating and buffering vibrations during the use of natural gas pipelines. Furthermore, the installation and connection of the support components to the external environment involves first setting up a concrete base in the external environment and then placing the support components on the base. If there is a small difference in height after the base is formed, it is difficult for the support components to flexibly adjust the support height, and the natural gas pipeline is easily damaged when subjected to gravity pressure.
[0004] Therefore, it is necessary to design an adjustable seismic support device for natural gas pipelines. Utility Model Content
[0005] To overcome the shortcomings of low vibration buffering effect and difficulty in flexibly adjusting the support height during the use of natural gas pipelines, the technical problem to be solved is to provide an adjustable seismic support device for natural gas pipelines.
[0006] The technical solution of this utility model is: an adjustable natural gas pipeline seismic support device, comprising: a base and a compression box, the compression box being provided on both sides of the base, the base having a cavity, the compression box having a gas-liquid cavity inside, the bottom of the gas-liquid cavity being connected to the bottom of the cavity of the base; an injection head, the injection head being provided on the top of the compression box; a connecting seat, the connecting seat being slidably provided in the cavity of the base; and a support ring, the support ring being provided on the top of the connecting seat.
[0007] In one embodiment, it further includes: a fixing block, with fixing blocks symmetrically arranged on both sides of the connecting seat; and a limiting post, with limiting posts symmetrically arranged on both sides of the base, the limiting posts passing through the fixing blocks directly opposite each other.
[0008] In one embodiment, it further includes: a compression block, wherein two arc-shaped grooves are opened inside the support ring, and a compression block is slidably provided inside each arc-shaped groove; and an elastic element, wherein an elastic element is provided between the compression block and the arc-shaped groove.
[0009] In one embodiment, it further includes a viewing window, wherein the extrusion box and the base have a viewing window that extends through the sidewall.
[0010] In one embodiment, the contact side of the extrusion block with the natural gas pipeline is made of an elastic material.
[0011] The beneficial effects are as follows: when the natural gas pipeline vibrates, the natural gas pipeline causes the space volume between the cavity in the connecting seat and the base to change through the support ring. The transmission medium and compressed air in the gas-liquid cavity can keep the connecting seat and the base within a certain range of relative movement, thus achieving the effect of isolating and buffering the vibration of the natural gas pipeline to the base. Furthermore, by injecting different amounts of transmission medium and compressed air into the hydraulic cavity, the operator can adjust the relative position between the connecting seat and the base, which facilitates the connection between the concrete base and the natural gas pipeline.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Example
[0017] like Figures 1 to 3 As shown, an adjustable seismic support device for natural gas pipelines includes: a base 1, a compression box 2, an injection head 202, a connecting seat 3, and a support ring 4;
[0018] The base 1 has extrusion chambers 2 on both horizontal sides. The base 1 has a cavity. The extrusion chamber 2 has a gas-liquid chamber 201 inside. The bottom of the gas-liquid chamber 201 is connected to the bottom of the cavity of the base 1. The top side of the extrusion chamber 2 has an injection head 202 connected to the gas-liquid chamber 201. The top cavity of the base 1 has a sliding connecting seat 3. The top of the connecting seat 3 has a support ring 4. The support ring 4 includes two semi-circular arc blocks and a connecting bolt.
[0019] For example, during installation, the natural gas pipeline is placed between the arc blocks of the support ring 4 and fixed with connecting bolts, so that the natural gas pipeline is connected to the support device through the support ring 4. After installation, the operator injects a certain amount of transmission medium similar to hydraulic oil into the gas-liquid chamber 201 through the injection head 202. After injection, compressed air is injected into the gas-liquid chamber 201 through the injection head 202, so that the support device just contacts the concrete base after supporting the natural gas pipeline. Then, the base 1 is connected to the concrete base set in the external environment. When the natural gas pipeline vibrates during use, the natural gas pipeline drives the connecting seat 3 to move relative to the base 1 through the support ring 4. When the volume of space formed between the cavities in seat 1 changes, the transmission medium and compressed air in the gas-liquid chamber 201 can maintain a certain relative range of movement between the connecting seat 3 and the base 1. For example, the connecting seat 3 can move closer to the base 1 by squeezing the transmission medium and compressed air, thus achieving the effect of isolating and buffering the vibration of the natural gas pipeline to the base 1, avoiding damage to the pipeline caused by forcibly suppressing the vibration of the natural gas pipeline or the vibration transmission forming resonance that affects the fixed support effect. Furthermore, by injecting different amounts of transmission medium and compressed air into the hydraulic chamber, the operator can adjust the relative position between the connecting seat 3 and the base 1, which facilitates the connection between the concrete base and the natural gas pipeline.
[0020] like Figures 1 to 3 As shown, it also includes a fixing block 10 and a limiting post 11. The fixing blocks 10 are symmetrically arranged on both horizontal sides of the connecting seat 3, and the limiting posts 11 are symmetrically arranged on both horizontal sides of the base 1 and located directly below the fixing blocks 10. The limiting posts 11 all penetrate the fixing blocks 10 directly opposite each other.
[0021] The fixing block 10 and the limiting post 11 can limit the maximum relative distance between the connecting seat 3 and the base 1, so as to prevent the connecting seat 3 from detaching from the base 1 when the vibration amplitude of the natural gas pipeline is too large.
[0022] like Figure 2 As shown, it also includes an extrusion block 8, and the support ring 4 has symmetrical arc grooves 7 on the upper and lower sides inside, with extrusion blocks 8 slidably arranged inside the arc grooves 7; and an elastic element 9, with an elastic element 9 provided between the extrusion block 8 and the arc grooves 7.
[0023] After the natural gas pipeline is connected to the support ring 4, the compression block 8 is squeezed between the support ring 4 and the natural gas pipeline. When the natural gas pipeline vibrates slightly, the compression block 8 and the elastic element 9 can buffer the vibration between the natural gas pipeline and the support ring 4, thereby improving the device's vibration buffering effect on the natural gas pipeline.
[0024] like Figures 1 to 3 As shown, it also includes a viewing window 12, and the extrusion box 2 and the base 1 are provided with a viewing window 12 that penetrates the side wall on the horizontal side.
[0025] The viewing window 12 on the side of the base 1 allows the operator to easily observe the injection volume and injection status when injecting transmission medium and compressed air.
[0026] The contact side of the extrusion block 8 with the natural gas pipeline is made of elastic material.
[0027] The compression block 8, which is made of elastic material on the contact side with the natural gas pipeline, can further buffer the vibration transmission of the natural gas pipeline to the support ring 4.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
