[0024] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0025] As shown in the figure, the seismic fixing structure for fixing the pipeline on the top of the floor slab of this embodiment includes a shock absorber 1, a fixing frame 4 for fixing the shock absorber 1, a four-arc splicing ring 5 is arranged at the center of the fixing frame 4, and the four-arc splicing ring 5 includes a first arc wall 51 arranged at the upper position of the shock absorber 1 and the lower position of the shock absorber 1 and a second arc wall 52 for connecting with the shock absorber 1, or;

[0026] A first arc wall 51 disposed at the left side and the right side of the shock absorber 1 and a second arc wall 52 for connecting with the shock absorber 1;

[0027] The first arc wall 51 abuts against the second arc wall 52 adjacent thereto. The first arc wall 51 is provided with at least one arc groove 511 at a position corresponding to the second arc wall 52. The second arc wall 52 is provided with an arc slope 521 at a position corresponding to each arc groove 511 on the first arc wall 51 adjacent thereto. The arc slope 521 can be embedded in the arc groove 511 and abut against it. The arc slope 521 can slide along the surface of the arc groove 511. The first arc wall 51 and the second arc wall 52 are combined to form a through hole 6 for placing an external pipe.

[0028] When the present scheme is implemented, the shock absorber 1, the fixing frame 4 and the four-arc splicing ring 5 provided in the present scheme work together to form an earthquake-resistant structure. First, the technicians in this field select the shock absorber 1 according to the actual situation on site. The shock absorber 1 in the present scheme can be a spring shock absorber 1, an air shock absorber 1, a rubber shock absorber 1, or a composite shock absorber 1 composed of a variety of shock absorbing elements such as rubber or springs. The fixing frame 4 of the present scheme can be made of carbon steel or stainless steel to ensure strength and stability. The fixing frame 4 is fixedly installed on the top of the floor slab and needs to be installed. The position of the pipeline; the four-arc splicing ring 5 in this scheme is the key to earthquake resistance. When the technicians in this field adopt the arrangement of the first arc wall 51 up and down, first align the lower first arc wall 51 with the bottom of the shock absorber 1, and then let the arc slope 521 corresponding to the second arc wall 52 be embedded in the arc groove 511 of the first arc wall 51. If necessary, molybdenum disulfide lubricant can be applied to reduce friction, and then the upper first and second arc walls are installed; the left and right arrangement is the same. The installation of this four-arc splicing ring 5 can also be completed in the production workshop when the four-arc splicing ring 5 is produced, that is, when the first arc wall 5 is produced 1 and the second arc wall 52, directly set the arc groove 511 and the arc slope 521 in the corresponding position and connect the first arc wall 51 and the second arc wall 52 to form a complete four-arc splicing ring 5, the first and second arc walls are closely abutted, the arc slope 521 and the arc groove 511 are completely embedded and slide smoothly, and the four-arc splicing ring 5 is adjusted to make the combined through hole 6 fit the pipe diameter; when installing the pipeline, it is necessary to ensure that the center line of the pipeline coincides with the center line of the through hole 6 of the four-arc splicing ring 5. Those skilled in the art can also use the method of wrapping the contact between the pipeline and the four-arc splicing ring 5 Wrap around rubber pad for cushioning; when an earthquake occurs, the pipe on the top of the floor will produce irregular shaking, and the pipe will hit the inner wall of the four-arc splicing ring 5 at this time. When the pipe hits the first arc wall 51 of the four-arc splicing ring 5, the first arc wall 51 will be displaced. At this time, the connection between the first arc wall 51 and the second arc wall 52 will slide to push the second arc wall 52 to move toward the shock absorber 1, and then transmit the vibration to the shock absorber 1, and then weaken the vibration intensity through the shock absorber 1. It has good anti-seismic effect, can adapt to vibrations from different directions, has a simple structure, and is easy to install.

[0029] As an improved specific embodiment, a sliding rod 512 is provided in the arc groove 511, a sliding cavity 522 for accommodating the sliding rod 512 is opened in the middle of the arc slope 521, and a limited position slide 523 is opened on the side wall facing the sliding rod 512. The sliding cavity 522 is connected to the slide, and the sliding rod 512 is partially inserted in the sliding cavity 522 and slidably cooperates with the sliding cavity 522. The outer peripheral wall of the sliding rod 512 can be against the inner wall of the slide.

[0030] When the present scheme is implemented, a slide bar 512 is arranged in the arc groove 511, and a slide cavity 522 is arranged in the middle of the arc slope 521. The slide cavity 522 in the present scheme can adapt to the slide bar 512, and the slide cavity 522 is connected to the limiting slideway 523. During installation, the slide bar 512 is partially inserted into the slide cavity 522 to ensure that it can slide smoothly in the slide cavity 522. The outer peripheral wall of the slide bar 512 and the inner wall of the slideway are tightly against each other to play a limiting role. In this way, during an earthquake, the four-arc splicing ring 5 is adaptively adjusted with the vibration, and the slide bar 512 cooperates with the slide cavity 522 and the slideway to limit the relative sliding range of the arc slope 521 and the arc groove 511, accurately disperses the pipeline stress, and effectively ensures the stability and safety of the pipeline during an earthquake. In addition, the slide bar 512 is not easy to deviate from the slideway, has a good limiting effect, and is not easy to be damaged.

[0031] As an improved specific implementation, a stopper 513 is provided at one end of the slide rod 512 connected to the slide cavity 522. The stopper 513 and the slide rod 512 are arranged in a T shape. The stopper 513 is placed in the slide cavity 522 and slides with it. The stopper 513 can abut against the inner wall of the slide cavity 522.

[0032] When the present scheme is implemented, the cooperation between the block 513 and the sliding cavity 522 greatly improves the structural stability. In the installation process of the four-arc splicing ring 5, the sliding cavity 522 of the arc slope 521 is adapted to the sliding rod 512 in the arc groove 511, and the block 513 arranged in a T shape at one end of the sliding rod 512 is located inside the sliding cavity 522. During installation, it is ensured that the block 513 can slide smoothly in the sliding cavity 522. When an earthquake occurs, the four-arc splicing ring 5 is adaptively adjusted due to the vibration, and the block 513 is against the inner wall of the sliding cavity 522, which effectively limits the excessive displacement of the sliding rod 512 and prevents the arc slope 521 from separating from the arc groove 511, further stabilizing the structure of the four-arc splicing ring 5, and effectively ensuring the stability and safety of the pipeline in a complex vibration environment.

[0033] As an improved specific implementation, a pulley 514 is provided on the side wall of the stopper 513 facing the slide bar 512 , and one pulley 514 is provided on both sides of the slide bar 512 , and the pulley 514 is slidably connected to the inner wall of the slide cavity 522 .

[0034] When implementing this solution, a pulley 514 is pre-arranged on the side wall of the stopper 513 facing the slide bar 512, and there is one pulley on each side of the slide bar 512. In the actual installation process, when the arc slope 521 of the four-arc splicing ring 5 is assembled with the arc groove 511, it is necessary to ensure that these pulleys 514 are closely fitted with the inner wall of the sliding cavity 522. In this way, when the earthquake causes vibration, the pulley 514 can slide smoothly on the inner wall of the sliding cavity 522 during the adaptive adjustment of the four-arc splicing ring 5, which greatly reduces the friction resistance and allows the arc slope 521 to slide along the arc groove 5 The sliding of 11 is more efficient, which effectively guarantees the flexible operation of the seismic fixed structure in a complex vibration environment. In other schemes, technical personnel in this field can also set an elastic structure between the pulley 514 and the block 513 or between the pulley 514 and the inner wall of the sliding cavity 522 to facilitate installation so that the pulley 514 can be retracted and extended during installation, which is convenient for installation. Since the present scheme preferably adopts the method of pre-setting the pulley 514 on the block 513, the pulley 514 in the present scheme can be adapted to the sliding cavity 522, and the installation method is simple.

[0035] As an improved specific implementation, a wheel rail 524 is provided along the length direction of the sliding cavity 522 on the inner wall on one side where the sliding cavity 522 contacts the pulley 514, corresponding to each pulley 514 position, and a long groove 515 is provided on the arc groove 511 corresponding to the position of the wheel rail 524, and the wheel rail 524 can be embedded in the long groove 515.

[0036] When the present solution is implemented, the inner wall of the sliding cavity 522 of the four-arc splicing ring 5 is pre-arranged along the length direction of the sliding cavity 522 corresponding to each pulley 514 position. During installation, the block 513 with the pulley 514 is placed into the sliding cavity 522 to allow the pulley 514 to accurately fall into the wheel rail 524. At the same time, a long groove 515 is opened on the arc groove 511 corresponding to the position of the wheel rail 524, and the wheel rail 524 is embedded in the long groove 515. Through this close cooperation, when the earthquake triggers the four-arc splicing ring 5 to slide adaptively, the pulley 514 always runs in the wheel rail 524, and at the same time, it can also prevent the first arc wall 51 and the second arc wall 52 from being easily loosened during movement, thereby reducing the risk of the pulley 514 being separated from the wheel rail 524, effectively protecting the safety of the pipeline, and improving the earthquake resistance effect.

[0037] As an improved specific implementation, a tension spring 53 is provided between the inner wall of the sliding cavity 522 and the sliding rod 512 , and one end of the spring is connected to the sliding rod 512 , and the other end is connected to the inner wall of the sliding cavity 522 .

[0038] When the present solution is implemented, technicians in this field connect one end of the tension spring 53 to the slide rod 512 and the other end to the inner wall of the slide cavity. When the pipeline is not affected by vibration, the four-arc splicing ring 5 will not be deformed, and the tension spring 53 will not be stretched at this time. When an earthquake occurs, the pipeline is affected by the vibration, and the first arc wall 51 and the second arc wall 52 on the four-arc splicing ring 5 are displaced. At this time, the slide rod 512 starts to slide, thereby driving the tension spring 53 to deform. At this time, the tension of the spring can weaken the impact of some vibrations on the pipeline, reduce the vibration amplitude, and improve the connection stability. After the vibration disappears, the tension spring 53 is reset and the pipeline can be stably inserted into the four-arc splicing ring 5. The structure is simple and the earthquake resistance effect is good.

[0039] As an improved specific embodiment, a rotation groove 525 is centrally arranged on the second arc wall 52 corresponding to the position of the shock absorber 1, a fixing rod 2 is arranged on the shock absorber 1 toward the fixing frame 4, and a transmission rod 3 is arranged toward the second arc wall 52, and the transmission rod 3 is partially inserted in the rotation groove 525 and rotates therewith.

[0040] When implementing this scheme, this scheme adopts setting a rotating groove 525 at the central position of the second arc wall 52. After the centrally set rotating groove 525 is connected to the transmission rod 3, the transmission rod 3 can quickly receive vibrations from different directions, the vibration transmission efficiency is higher, and the connection is more stable. The fixing rod 2 can fix the shock absorber 1 and the fixing frame 4 to prevent the shock absorber 1 from shaking itself.

[0041] As an improved specific embodiment, the rotating groove 525 is a spherical rotating groove 525, and a rotating ball 31 is provided at one end of the transmission rod 3 connected to the rotating groove 525. The rotating ball 31 is fixedly connected to the transmission rod 3, and the rotating ball 31 is partially embedded in the rotating groove 525 and rotates therewith.

[0042] When implementing this scheme, this scheme adopts setting a rotating bead 31 at one end where the transmission rod 3 is connected to the rotating groove 525. The rotating bead 31 is more adapted to the spherical rotating groove 525, and the rotating bead 31 has an arc-shaped surface, and the rotation is smoother. The rotating bead 31 and the transmission rod 3 in this scheme can be an integrally formed setting or a detachable connection. This scheme preferably configures the rotating bead 31 and the transmission rod 3 as an integrally formed setting, which is more convenient when manufacturing the transmission rod 3 and the rotating bead 31, saving time and effort.

[0043] As an improved specific implementation, the shock absorber 1 is a rubber shock absorber 1.

[0044] The present solution preferably uses a rubber shock absorber 1 , which can adapt to high-frequency vibration environments, has good shock absorption effects, and has a long service life.

[0045] As an improved specific implementation, a soft pad 54 is glued to the inner wall of the four-arc splicing ring 5 .

[0046] When an earthquake occurs, the shock absorber 1 converts vibration energy, and the four-arc splicing ring 5 disperses the pipeline stress through the sliding adaptive adjustment of the arc slope 521 and the arc groove 511 according to the vibration direction. The soft pad 54 further absorbs the vibration, and comprehensively guarantees the safety and stability of the pipeline during the earthquake. The soft pad 54 is glued, and it is very convenient to disassemble, assemble and replace.

[0047] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
