Description

Technical Field

[0001] This utility model relates to the field of seismic support technology, specifically to a seismic support for underground integrated pipe gallery. Background Technology

[0002] Underground utility tunnels refer to structures and ancillary facilities located below the city surface to accommodate two or more types of public utility pipelines or professional pipelines. Incorporating public utility pipelines into the tunnel avoids the hassle of repeated road excavation for burying or maintaining pipelines. Furthermore, since the pipelines do not come into contact with soil or groundwater, soil corrosion is avoided, extending the pipelines' lifespan. Because the types of public utility pipelines within the underground tunnel differ, they need to be laid separately. Traditional laying methods often involve directly fixing them to mounting frames, which lack seismic resistance. External vibrations can easily damage the pipelines. To reduce pipeline damage, a seismic-resistant support system for underground utility tunnels is proposed.

[0003] For example, the seismic support for an underground integrated utility tunnel disclosed in authorization announcement number CN210034635U includes a base located inside the underground integrated utility tunnel. The base is provided with a seismic frame in a trapezoidal structure. Multiple horizontal plates and multiple inclined plates are horizontally arranged inside the seismic frame. Every two inclined plates and one horizontal plate are combined to form a triangular frame structure, and the pipes are confined within the triangular frame structure. The unique trapezoidal tower design decomposes the structure into triangles of different specifications, which support each other to form a stable trapezoidal structure. It can be applied to the construction process of utility tunnels in sponge cities. Although it achieves high scalability of seismic bracing, allowing the number of horizontal plates, inclined plates, and partitions within the seismic frame to be set according to actual needs to accommodate different numbers of pipeline installations, it does not solve the problems of existing seismic bracing being unsuitable for flexibly adjusting and adapting to different support point spacings, unsuitable for center positioning and clamping fixed pipelines, and unsuitable for elastically offsetting vibrations experienced by pipelines, thus affecting the convenience of pipeline installation and the seismic effect. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-seismic support for underground integrated utility tunnels, so as to solve the problems mentioned in the background art, such as the inconvenience of flexibly adjusting and adapting to different support point spacings, the difficulty in center positioning and clamping the pipeline, and the inability to elastically offset the vibration of the pipeline, which affect the convenience of pipeline installation and the anti-seismic effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant support for an underground integrated utility tunnel, comprising an integrated utility tunnel body and an installation frame. The installation frame is provided on the inner wall of the integrated utility tunnel body. A limiting groove is provided on the surface of the installation frame. Multiple sets of equally spaced bearing blocks are provided at the top of the installation frame. Each bearing block has a limiting block at its bottom end, and the limiting blocks are slidably connected to the limiting groove. Multiple sets of equally spaced pin holes are provided on the side wall of the installation frame. A locking pin is provided inside each pin hole, extending into the interior of the limiting block, and the locking pin is engaged with the limiting groove. The bearing blocks are connected by threaded connections. Upper and lower connecting rods are movably mounted on the side walls of each bearing block. Connecting blocks are provided on the outside of each bearing block, and these connecting blocks are movably connected to the lower and upper connecting rods. Shock absorbers are provided on the side walls of each upper connecting rod. An upper movable shaft is provided at the end of each shock absorber near the upper connecting rod, and the shock absorber is movably connected to the upper connecting rod via the upper movable shaft. A lower movable shaft is provided at the end of each shock absorber near the lower connecting rod, and the shock absorber is movably connected to the lower connecting rod via the lower movable shaft. C-shaped brackets are provided on the side walls of each connecting block.

[0006] Preferably, each of the C-shaped frames is provided with a first hinge shaft on its side wall, and a first clamping arm is movably mounted on the surface of each first hinge shaft.

[0007] Preferably, a lever is movably mounted on one end of each of the first clamping arms, and a first linkage arm is movably mounted on the surface of the lever on one side of each of the first clamping arms.

[0008] Preferably, each lever has a spring on its side wall, and the spring is connected to the C-shaped frame.

[0009] Preferably, a second clamping arm is provided at the end of the first linkage arm away from the first clamping arm, and the second clamping arm is movably connected to the first linkage arm.

[0010] Preferably, the surface of the second clamping arm is provided with a second hinge shaft, and the second clamping arm is movably connected to the C-frame through the second hinge shaft.

[0011] Preferably, the second clamping arm is movably mounted with a second linkage arm at the end away from the first linkage arm, and the second linkage arm is movably mounted with a third clamping arm at the end away from the second clamping arm.

[0012] Preferably, the surface of the third clamping arm is provided with a third hinge shaft, and the third clamping arm is movably connected to the C-frame through the third hinge shaft, and the ends of the first clamping arm, the second clamping arm, and the third clamping arm that are close to each other are all provided with clamping blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the seismic brace not only realizes flexible adjustment to adapt to different support point spacing, which facilitates the center positioning and clamping of pipelines and elastically offsets the vibrations of pipelines, but also improves the convenience of pipeline installation and the seismic effect. Install the mounting bracket on the inner wall of the integrated utility tunnel. First, adjust the different support points according to the length of the pipeline. Take the bearing block, insert the limiting block into the limiting groove, and move the bearing block. The bearing block will drive the limiting block to move inside the limiting groove. Install multiple sets of bearing blocks in sequence inside the mounting bracket and adjust the spacing. Then, insert the locking pin into the corresponding pin hole of the limiting block and tighten the locking pin to fix the limiting block in the mounting bracket. Then, move the lever. The lever will drive the first clamping arm to rotate around the first hinge axis. The lever will pull the spring and drive the first linkage arm to rotate. The first linkage arm will drive the second clamping arm to rotate around the second hinge axis. The second clamping arm will drive the third clamping arm to rotate around the third hinge axis. The shaft rotates to cause the clamping blocks, second clamping arm, and third clamping arm to rotate outward synchronously, opening the three sets of clamping blocks. The pipeline is placed between the three sets of clamping blocks. The lever is released, and under the elastic cooperation of the spring, the lever is driven to return to its original position. Through the structural linkage of the first and second linkage arms, the first, second, and third clamping arms are driven to rotate synchronously towards the center position of the C-frame. The first, second, and third clamping arms drive the clamping blocks to rotate synchronously and contact the outer wall of the pipeline. The clamping blocks clamp and fix the pipeline, thereby completing the pipeline fixing and installation work. It realizes flexible adjustment to adapt to different support point spacings, facilitates the center positioning and clamping fixation of the pipeline, and improves the convenience of pipeline installation. If the pipeline is subjected to external vibration, the vibration is transmitted through the pipeline to the C-frame. The C-frame then moves the connecting block, which in turn rotates the upper connecting rod. The lower connecting rod provides movable support for the connecting block. The upper connecting rod, through the upper movable shaft, drives the shock absorber to rotate and deform. The lower movable shaft provides movable support for the shock absorber. With the support of the shock absorber's own structural characteristics, the shock absorber cancels out this part of the vibration, thereby preventing external vibration from damaging the pipeline. This facilitates elastic cancellation of vibrations to the pipeline and improves the seismic resistance. Attached Figure Description

[0017] Please see Figure 1-5 This utility model provides an embodiment of an underground integrated utility tunnel seismic support, comprising an integrated utility tunnel body 2 and an mounting frame 1. The mounting frame 1 is provided on the inner wall of the integrated utility tunnel body 2. A limiting groove 7 is provided on the surface of the mounting frame 1.

The side wall of the connecting block 9 is provided with the C-shaped frame 4. Install the mounting bracket 1 on the inner wall of the integrated pipe gallery body 2. First, adjust the different support points according to the length of the pipeline. Take the bearing block 3, insert the limiting block 8 into the limiting groove 7, and move the bearing block 3. Under the sliding cooperation between the limiting block 8 and the limiting groove 7, the bearing block 3 drives the limiting block 8 to move inside the limiting groove 7. Install multiple sets of bearing blocks 3 in sequence inside the mounting bracket 1 and adjust the spacing. Then, insert the locking pin 5 into the limiting block 8 through the corresponding pin hole 6 and tighten the locking pin 5. With the threaded connection between the locking pin 5 and the limiting block 8, the limiting block 8 is fixed in the mounting bracket 1. Then, move the lever 15. The lever 15 drives the first clamping arm 18 to rotate around the first hinge shaft 17. The lever 15 pulls the spring 16 and simultaneously drives the first linkage arm 20 to rotate. The first linkage arm 20 drives the second clamping arm 22 to rotate around the second hinge shaft 21. The second clamping arm 22 passes through... The second linkage arm 23 drives the third clamping arm 25 to rotate around the third hinge shaft 24, so that the clamping block 19, the second clamping arm 22 and the third clamping arm 25 rotate outward synchronously to open the three sets of clamping blocks 19. The pipeline is placed between the three sets of clamping blocks 19. The lever 15 is released. Under the elastic cooperation of the spring 16, the lever 15 is driven to return to its original position by the spring 16. Through the structural linkage of the first linkage arm 20 and the second linkage arm 23, the first clamping arm 18, the second clamping arm 22 and the third clamping arm 25 rotate synchronously towards the center position of the C-shaped frame 4. The first clamping arm 18, the second clamping arm 22 and the third clamping arm 25 drive the clamping block 19 to rotate synchronously and contact the outer wall of the pipeline. The clamping block 19 clamps and fixes the pipeline, thereby completing the fixed installation of the pipeline. It realizes flexible adjustment and adaptation to different support point spacing, facilitates the center positioning and clamping fixation of the pipeline, and improves the convenience of pipeline installation. The C-frame 4 is provided with a first hinge shaft 17 on its side wall, and a first clamping arm 18 is movably mounted on the surface of the first hinge shaft 17. A lever 15 is movably mounted on one end of each of the first clamping arms 18. A first linkage arm 20 is movably mounted on the surface of the lever 15 on one side of the first clamping arm 18. A spring 16 is provided on the side wall of the lever 15, and the spring 16 is connected to the C-shaped frame 4. The first linkage arm 20 is provided with a second clamping arm 22 at the end away from the first clamping arm 18, and the second clamping arm 22 is movably connected to the first linkage arm 20. The surface of the second clamping arm 22 is provided with a second hinge shaft 21, and the second clamping arm 22 is movably connected to the C-shaped frame 4 through the second hinge shaft 21. The second clamping arm 22 is movably mounted with a second linkage arm 23 at the end away from the first linkage arm 20, and a third clamping arm 25 is movably mounted at the end of the second linkage arm 23 away from the second clamping arm 22. The surface of the third clamping arm 25 is provided with a third hinge shaft 24, and the third clamping arm 25 is movably connected to the C-shaped frame 4 through the third hinge shaft 24. The first clamping arm 18, the second clamping arm 22, and the third clamping arm 25 are all provided with clamping blocks 19 at their respective close ends. If the pipeline is subjected to external vibration, the vibration is transmitted through the pipeline to the C-frame 4. The C-frame 4 drives the connecting block 9 to move, and the connecting block 9 drives the upper connecting rod 12 to rotate. The lower connecting rod 10 provides movable support for the connecting block 9. The upper connecting rod 12 drives the shock absorber 13 to rotate and deform through the upper movable shaft 14. The lower movable shaft 11 provides movable support for the shock absorber 13. With the support of the structural characteristics of the shock absorber 13, the shock absorber 13 cancels out the vibration, thereby avoiding damage to the pipeline caused by external vibration. This facilitates elastic cancellation of vibrations to the pipeline and improves the seismic resistance.

[0018] Working principle: Install the mounting bracket 1 on the inner wall of the integrated pipe gallery body 2. Adjust the support points according to the length of the pipeline. Take the bearing block 3 and insert the limiting block 8 into the limiting groove 7. Move the bearing block 3, which will drive the limiting block 8 to move inside the limiting groove 7. Install multiple sets of bearing blocks 3 in sequence inside the mounting bracket 1 and adjust the spacing. Then, insert the locking pin 5 into the corresponding pin hole 6 into the limiting block 8 and tighten the locking pin 5. With the threaded connection between the locking pin 5 and the limiting block 8, the limiting block 8 is fixed in the mounting bracket 1. Then, by moving lever 15, the first clamping arm 18 rotates around the first hinge shaft 17. Lever 15 also pulls the spring 16, simultaneously causing the first linkage arm 20 to rotate. The first linkage arm 20 then rotates the second clamping arm 22 around the second hinge shaft 21. The second clamping arm 22, through the second linkage arm 23, rotates the third clamping arm 25 around the third hinge shaft 24. This causes the clamping blocks 19, the second clamping arm 22, and the third clamping arm 25 to rotate outward synchronously, opening the three sets of clamping blocks 19 and placing the pipeline within them. Between positions 19 and 16, release lever 15. With the elastic cooperation of spring 16, spring 16 drives lever 15 to reset. Through the structural linkage of first linkage arm 20 and second linkage arm 23, first clamping arm 18, second clamping arm 22, and third clamping arm 25 synchronously rotate towards the center position of C-frame 4. First clamping arm 18, second clamping arm 22, and third clamping arm 25 drive clamping block 19 to rotate synchronously and contact the outer wall of the pipeline. Clamping block 19 clamps and fixes the pipeline, thus completing the pipeline's fixed installation. If the pipeline is subjected to external... Vibration, external vibration, is transmitted to the C-frame 4 through the pipeline. The C-frame 4 drives the connecting block 9 to move, and the connecting block 9 drives the upper connecting rod 12 to rotate. The lower connecting rod 10 provides movable support for the connecting block 9. The upper connecting rod 12 drives the shock absorber 13 to rotate and deform through the upper movable shaft 14. The lower movable shaft 11 provides movable support for the shock absorber 13. With the support of the structural characteristics of the shock absorber 13, the shock absorber 13 cancels out this part of the vibration, thereby avoiding damage to the pipeline caused by external vibration.
