[0002] Gas pipelines refer to specialized pipeline systems used to transport natural gas, liquefied petroleum gas, and other gas-powered gases. Their core function is to connect gas sources with end-user gas equipment. Gas pipeline support brackets are used to support the pipeline and fix its position, reducing vibrations or displacements caused by external forces.

[0003] In the existing technology, gas pipelines are generally rigidly installed and fixed when they are supported and installed. When the gas pipeline is subjected to vibration from the external environment, the rigid installation position will be damaged by vibration, which will not only cause unstable support, but also easily lead to damage to the surface of the gas pipeline.

[0004] Therefore, this utility model provides a seismic support device for gas pipelines. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown, the gas pipeline seismic support device of this utility model includes an installation plate 1; a pair of symmetrically distributed first fixing columns 11 are fixedly connected to the bottom end of the installation plate 1, and a pair of symmetrically distributed protrusions are provided on the outer side wall of the first fixing columns 11; a first threaded groove 12 is opened at the bottom end of the first fixing columns 11; an upper arc plate 14 is installed in the middle of the bottom end of the installation plate 1 through an elastic support mechanism; a lower arc plate 15 is provided below the upper arc plate 14, and installation holes 16 are opened on both sides of the upper arc plate 14 and the lower arc plate 15; a rubber layer 17 is fixedly connected to the inner arc wall of the upper arc plate 14 and the lower arc plate 15; a first threaded post 13 is provided in the first threaded groove 12, and the first threaded post 13 passes through the installation holes 16 of the lower arc plate 15 and the upper arc plate 14 and is threadedly connected in the first threaded groove 12; in the prior art, when supporting gas pipelines... During installation, gas pipelines are typically rigidly fixed. When subjected to vibrations from the external environment, these rigid installation positions can be damaged, leading to instability and surface damage. Therefore, this invention, in practical operation, places the gas pipeline against the bottom surface of the upper arc-shaped plate 14. A pair of first threaded posts 13 are then inserted into the mounting holes 16 of the upper and lower arc-shaped plates 14 and threaded into the first threaded grooves 12. Both first threaded posts 13 are installed within the first threaded grooves 12. The lower arc-shaped plate 15 is then rotated sequentially to move upwards and fit against the gas pipeline below it. The elastic support mechanism and the pair of first threaded posts 13 ensure stable placement of the gas pipeline. Simultaneously, the elastic support mechanism provides cushioning and provides a degree of shock resistance, preventing damage and loosening of the gas pipeline and installation position caused by rigid installation.

[0024] The elastic support mechanism includes a second fixed column 2; the second fixed column 2 is fixedly connected to the middle of the bottom end of the mounting plate 1; a first cavity 21 is opened inside the second fixed column 2; a sliding plate 22 is slidably connected inside the first cavity 21, and the top view of both the sliding plate 22 and the first cavity 21 is square; the bottom end of the sliding plate 22 is fixedly connected to the bottom end of the first cavity 21 by an anti-vibration spring 23; a buffer column 24 is fixedly connected to the bottom end of the sliding plate 22, and the bottom end of the buffer column 24 extends out of the first fixed column 11 and is fixedly connected to the top end of the upper arc plate 14; during operation, the gas pipeline is first attached to the arc surface of the bottom end of the upper arc plate 14, and at this time the anti-vibration spring 23 is in a stretched state. After the first threaded column 13 is installed, the reverse force of the anti-vibration spring 23 is used to ensure the installation stability of the gas pipeline, and at the same time, it has a certain upward buffering property. In addition, the rubber layer 17 is set to effectively ensure the anti-vibration buffering effect.

[0025] The first threaded post 13 is threaded with a fixing nut 25, and the fixing nut 25 is located above the upper arc plate 14. During operation, the fixing nut 25 is not used normally. When the gas pipeline needs to be rigidly installed according to the actual situation, the fixing nut 25 can be attached to the installation position of the upper arc plate 14 to ensure rigid installation. At the same time, the setting of the fixing nut 25 also has a certain protective function, so that the whole device can still ensure the support of gas flow when the elastic support mechanism fails.

[0026] A first groove 3 is provided on the outer wall of the first threaded post 13; a first groove 31 is provided on the inner wall of the first threaded groove 12; a push plate 33 is slidably connected in the first groove 31; a locking block 32 is fixedly connected to the side wall of the push plate 33 by a spring; a second threaded post 34 is threadedly connected to the outer wall of the first fixed post 11, and the end of the second threaded post 34 extends into the first groove 31 and is rotatably connected to the side wall of the push plate 33; during operation, after the gas is installed through, in order to ensure stability, the second threaded post 34 is rotated so that the push plate 33 pushes the locking block 32 into the first groove 3 of the first threaded post 13, or the locking block 32 can be pushed first, and then the first threaded post 13 can be rotated so that the locking block 32 is locked into the first groove 3, thereby completing the locking of the first threaded post 13, avoiding reverse rotation and ensuring installation stability.

[0027] The slide plate 22 has a locking hole 4 on its side wall; the second fixing column 2 has a set of through holes 41, which are connected to the first cavity 21; the through hole 41 is provided with a positioning rod 42; during operation, the positioning rod 42 is only used when installing the gas pipeline. The upper arc plate 14 is raised to the rated position, and the anti-vibration spring 23 is in a stretched state. Then the positioning rod 42 is inserted into the through hole 41 and locked into the locking hole 4, so that the stretch of the anti-vibration spring 23 remains unchanged, which facilitates the placement and fit of the gas pipeline. After the gas pipeline is installed, the positioning rod 42 is pulled out to ensure the use of the elastic buffer of the elastic support mechanism.

[0028] A second sliding groove 5 is provided on the outer side wall of the first fixed column 11; a third sliding groove 51 is provided on the inner walls of both sides of the second sliding groove 5; an inclined plate 52 is slidably connected in the third sliding groove 51, and the end of the inclined plate 52 is fixed to the outer side wall of the upper arc plate 14; a rotating column 53 is rotatably connected on the inclined plate 52, and the rotating column 53 is slidably connected in the third sliding groove 51; during operation, the arrangement of the inclined plate 52, the second sliding groove 5, the third sliding groove 51 and the rotating column 53 can play a secondary protection role, ensuring that the upper arc plate 14 moves vertically up and down without swaying left and right.

[0029] Working principle: The gas pipeline is attached to the bottom surface of the upper arc plate 14. Then, a pair of first threaded posts 13 are inserted into the mounting holes 16 of the upper arc plate 14 and the lower arc plate 15 and threaded into the first threaded grooves 12. Both first threaded posts 13 are installed in the first threaded grooves 12. Then, the lower arc plate 15 is rotated to move upward and attach to the position below the gas pipeline. The gas pipeline is then stably placed through the elastic support mechanism and the pair of first threaded posts 13. At the same time, the elastic support mechanism provides elastic buffering, which has a certain degree of shock resistance and avoids damage and loosening to the gas pipeline and installation position caused by rigid installation. First, the gas pipeline is attached to the bottom arc surface of the upper arc plate 14. At this time, the anti-vibration spring 23 is in a stretched state. After the first threaded posts 13 are installed, the reverse force of the anti-vibration spring 23 ensures the installation stability of the gas pipeline and has a certain upward buffering effect. The impact resistance, coupled with the rubber layer 17, effectively ensures the shock absorption effect. After the gas pipeline is installed, to ensure stability, the second threaded column 34 is rotated, allowing the push plate 33 to push the locking block 32 into the first groove 3 of the first threaded column 13. Alternatively, the locking block 32 can be pushed first, and then the first threaded column 13 can be rotated to allow the locking block 32 to be locked into the first groove 3, thereby completing the locking of the first threaded column 13 and avoiding reverse rotation, thus ensuring installation stability. The positioning rod 42 is only used when installing the gas pipeline. The upper arc plate 14 is raised to the rated position, and the shock-absorbing spring 23 is in a stretched state. Then, the positioning rod 42 is inserted into the through hole 41 and locked into the locking hole 4, thus completing the tension of the shock-absorbing spring 23, which facilitates the placement and fit of the gas pipeline. After the gas pipeline is installed, the positioning rod 42 is pulled out to ensure the use of the elastic support mechanism for elastic buffering.
