Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular, to a pipe support device. Furthermore, it also relates to an underground drainage system including the pipe support device. Background Technology

[0002] In construction engineering, concrete pipes are often used for drainage and other tasks. Concrete pipes are made of concrete or reinforced concrete and are used to transport fluids such as water, oil, and gas. Reinforced concrete pipes are typically laid directly in pits. However, the soil at the bottom of the pit is prone to settling over time, which can easily damage the concrete pipes and cause significant inconvenience. Furthermore, the pressure from the top and sides of the soil when burying the concrete pipes can reduce their lifespan.

[0003] Chinese Patent Publication No. CN213299034U discloses a support device for reinforced concrete pipe construction, including a support base and a base. The support base is located above the base, and fixing blocks are fixedly connected to both sides of the top of the base. This support device for reinforced concrete pipe construction supports the concrete pipe body through the base and support base, greatly reducing the impact of soil collapse on the concrete pipe body. The top plate isolates the soil above the concrete pipe, and the support rods isolate the soil on both sides of the concrete pipe, thereby reducing the stress on the concrete pipe and preventing it from being squeezed. However, the top plate and support rods of this device cannot effectively position and dampen the concrete pipe. During construction, the concrete pipe is prone to shaking, leading to surface wear. Furthermore, the support rods and top plate are installed using bolt connections, which is time-consuming, labor-intensive, and inefficient when multiple devices need to be assembled on-site.

[0015] The two ends of the first spring abut against the inner support block and the outer support block, respectively.

[0016] Furthermore, the clamping assembly also includes a guide member for guiding and limiting the sliding of the inner support frame. The guide member includes a first guide rod and a slider movably sleeved outside the first guide rod. The slider is located on both sides of the inner support block and connected to the outer wall of the inner support block.

[0017] The outer support block has a guide groove for installing guide components. The guide groove is located on both sides of the buffer groove and is connected to the buffer groove.

[0018] Furthermore, the locking component includes a first connecting block and a second connecting block respectively disposed on opposite sides of the outer support ring, and a locking structure for engaging and locking the first connecting block on one of the outer supports and the second connecting block on the other outer support.

[0019] The first connecting block has an installation groove for installing the locking structure, and the second connecting block has a snap-fit ​​groove for engaging with the locking structure and an unlocking hole communicating with the snap-fit ​​groove. The unlocking hole is used to insert an unlocking tool and push the locking structure inward by the unlocking tool so that the locking structure disengages from the snap-fit ​​groove.

[0020] Furthermore, the locking structure includes a fixed rod fixed in the mounting groove, a second guide rod perpendicular to the fixed rod and fixed on the fixed rod, a locking frame located on both sides of the fixed rod and slidably sleeved on the second guide rod, and a second spring pressing between the fixed rod and the locking frame;

[0021] The second spring applies an elastic force to the locking bracket along the mounting groove, thereby driving the locking bracket to extend out of the mounting groove and engage with the locking groove.

[0022] Furthermore, the support mechanism also includes a base plate, which is disposed on an outer support block in at least one outer support frame and is used for support and fixation relative to the ground.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0034] like Figure 1 As shown, the pipe support device of this embodiment includes a support mechanism 10 and a shock-absorbing positioning mechanism. The support mechanism 10 includes two outer support frames 11 and a locking member 12 for locking the two outer support frames 11 together. Preferably, the two outer support frames 11 have the same shape and structure. The locking member 12 is located outside the two outer support frames 11 and is fixedly installed on the two outer support frames 11. After the two outer support frames 11 are joined together, they are locked together by the locking member 12 to form a protective space for the pipe. Preferably, the shape of the protective space is an annular shape that matches the shape of the outer wall of the pipe. Thus, the support mechanism 10, through the cooperation of two outer supports 11 and locking elements 12, forms a stable protective space around the pipeline, effectively isolating it from external stress impacts and environmental influences, preventing external soil from squeezing and damaging the pipeline, ensuring the support and protection of the pipeline in complex environments, and extending the pipeline's service life. The locking elements 12 of the support mechanism 10 engage and lock the two outer supports 11 using a snap-fit ​​method, ensuring not only precise connection but also facilitating quick installation and disassembly. Multiple units can be quickly assembled on-site, simplifying the installation process, saving time and effort, and effectively improving construction efficiency. Furthermore, during construction, the snap-fit ​​connection prevents the outer supports 11 from loosening or failing due to construction vibrations, ensuring a stable and reliable connection.

[0035] The vibration damping and positioning mechanism includes clamping components 20 elastically installed within the outer support frame 11. The clamping components 20 in the two outer support frames 11 are symmetrically arranged within the protective space to elastically clamp the pipeline, reducing vibration transmission. Preferably, a clamping space is formed between the two clamping components 20, and this clamping space is adapted to the external shape of the pipeline. Thus, the vibration damping and positioning mechanism, through the two clamping components 20 located within the protective space, can elastically clamp the pipeline, achieving effective fixation and positioning. This absorbs and buffers pipeline vibration, reducing the risk of pipeline wear or loosening caused by vibration during construction, and improving the stability and safety of the pipeline. Furthermore, the two clamping components 20 can be used to adapt to pipelines of different sizes and models, offering high versatility and effectively expanding the application range to meet the support and protection needs of different scenarios.

[0036] like Figure 1 and Figure 2 As shown, the outer support frame 11 includes an outer support ring 111 and an outer support block 112 connected to the end of the outer support ring 111 away from the protected space. Specifically, the outer support ring 111 is semi-circular or arc-shaped and is used to protect the outer periphery of the pipe to prevent damage to the pipe from external stress. The outer support block 112 is located on the side of the outer support ring 111 away from the open end and is integrally formed with the outer support ring 111. Locking members 12 are symmetrically arranged on both sides of the outer support block 112 and fixedly connected to the outer wall of the outer support ring 111. A buffer groove 113 is provided in the outer support block 112 and / or the outer support ring 111. The buffer groove 113 is located at the bottom of the inner ring of the outer support ring 111 to elastically install the clamping assembly 20 and provide elastic buffer space.

[0037] like Figure 1 and Figure 2As shown, the clamping assembly 20 includes an inner support frame 21 and an elastic connector 22. The inner support frame 21 is located within the inner ring of the outer support ring 111 and is used to support the pipeline. The inner support frame 21 slides through the buffer groove 113, and the elastic connector 22 is pressed against the buffer groove 113 to apply an elastic clamping force towards the pipeline to the outer support frame 11. Specifically, the inner support frame 21 includes an inner support ring 211 and an inner support block 212 located at one end of the inner support ring 211 facing the buffer groove 113. The inner support ring 211 and the inner support block 212 are integrally formed. The inner support ring 211 is located within the inner ring of the outer support ring 111 to support the pipeline. Preferably, the inner wall shape of the inner support ring 211 is an arc shape adapted to the outer wall shape of the pipeline to increase the support area with the pipeline surface. The inner support block 212 slides through the buffer groove 113 along the height direction. An elastic support frame is mounted at the bottom of the inner support block 212. Both ends of the elastic connector 22 are fixed to the inner support block 212 and the outer support block 112 respectively, providing elastic buffering for the inner support frame 21 and reducing vibration transmission. Preferably, a limiting groove is provided at the lower end of the inner support block 212 to accommodate the elastic connector 22, preventing it from tilting and ensuring elastic buffering performance. Thus, through the cooperation of the inner support frame 21 and the elastic connector 22, the two clamping components 20 can be connected and elastically supported by the elastic connector 22, clamping the pipe within the two inner support rings 211. This achieves effective positioning and clamping of the pipe, effectively preventing the pipe from shaking due to vibrations during construction and avoiding damage to the pipe surface.

[0038] like Figure 2 As shown, the elastic connector 22 is disposed in the buffer groove 113 between the inner support block 212 and the outer support block 112. The elastic connector 22 includes a damper 221 and a first spring 222 sleeved on the outside of the damper 221. The two ends of the damper 221 are fixed to the inner support block 212 and the outer support block 112 respectively. The damper 221 is used to absorb vibration energy and enhance the shock absorption effect. The two ends of the first spring 222 also abut against the inner support block 212 and the outer support block 112 respectively. The first spring 222 is used to provide elastic restoring force to the inner support frame 21, so that the inner support frame 21 can be elastically buffered in the buffer groove 113.

[0039] like Figure 2As shown, the clamping assembly 20 also includes a guide member 23 for guiding and limiting the sliding of the inner support frame 21, thereby improving the stability of the sliding of the inner support frame 21. The guide member 23 includes a first guide rod 232 and a slider 231 movably sleeved outside the first guide rod 232. Specifically, the slider 231 is located on both sides of the inner support block 212 and fixed to the inner support block 212. A guide groove 114 is provided in the outer support block 112 and / or the outer support ring 111. The guide groove 114 is located on both sides of the buffer groove 113 and communicates with the buffer groove 113. The guide groove 114 is arranged along the height direction. The first guide rod 232 is placed in the guide groove 114 along the height direction, and both ends of the first guide rod 232 are fixed to the inner wall of the guide groove 114. Thus, when the pipeline is vibrated, the inner support 21 slides along the first guide rod 232 in the buffer groove 113, compressing the first spring 222 and the damper 221 to absorb vibration energy; after the vibration ends, the first spring 222 pushes the inner support 21 to reset, keeping the pipeline stable.

[0040] like Figure 1 and Figure 2 As shown, the clamping assembly 20 located below the pipe provides elastic support to the pipe through its inner support ring 211, while the clamping assembly 20 located above the pipe provides elastic clamping force to the pipe through its inner support ring 211, ensuring the pipe is stably positioned by the two inner support rings 211 and preventing shaking. Preferably, an anti-slip and wear-resistant pad is provided on the inner wall of the inner support ring 211 to prevent the internal pipe from sliding or shifting, further improving the stability and reliability of the pipe positioning. It also prevents mutual wear between the pipe and the inner wall of the inner support ring 211, extending the service life of the pipe and the device. Preferably, a rubber pad can be installed on the inner wall of the inner support ring 211 to further improve the cushioning and shock absorption effect.

[0041] like Figure 1 and Figure 3 As shown, the locking member 12 includes a first connecting block 121 and a second connecting block 122 respectively disposed on opposite sides of the outer support ring 111, and a locking structure 123 for engaging and locking the first connecting block 121 on one outer support frame 11 and the second connecting block 122 on the other outer support frame 11. The first connecting block 121 and the second connecting block 122 are both attached to the outer wall of the outer support ring 111 and are connected and fixed to the outer support ring 111. The first connecting block 121 and the second connecting block 122 are correspondingly disposed on the two outer support rings 111 so that after the two outer support frames 11 are connected, the first connecting block 121 can be correspondingly disposed on the second connecting block 122, and the two outer support frames 11 are locked by the locking structure 123.

[0042] The first connecting block 121 has a mounting groove 1211, with the opening of the mounting groove 1211 facing the first connecting block 121. The locking structure 123 is installed in the first connecting block 121 through the mounting groove 1211 and extends out of the opening of the mounting groove 1211 to engage with the second connecting block 122. The second connecting block 122 has a locking groove 1221 and an unlocking hole 1222 communicating with the locking groove 1221. The locking groove 1221 is coaxially corresponding to the mounting groove 1211 and is used for the locking structure 123 to extend into and engage with the locking structure 123 for locking. The unlocking hole 1222 is perpendicular to the locking groove 1221 and extends through the interior of the second connecting block 122. The unlocking hole 1222 is used to insert an unlocking tool to push the locking structure 123 inward, so that the locking structure 123 disengages from the locking groove 1221 to achieve unlocking.

[0043] like Figure 3 As shown, the locking structure 123 includes a fixed rod 1231, a second guide rod 1232, a locking element 12, and a second spring 1234. Specifically, the fixed rod 1231 is disposed within the mounting groove 1211 along the length direction of the mounting groove 1211 and fixed to the first connecting block 121. Preferably, the fixed rod 1231 is located at the center of the mounting groove 1211. The second guide rod 1232 is disposed perpendicular to the fixed rod 1231 within the mounting groove 1211 and fixed to the fixed rod 1231, and both ends of the second guide rod 1232 are fixed to the first connecting block 121. Preferably, the middle position of the second guide rod 1232 is fixed to the fixed rod 1231; preferably, two second guide rods 1232 are provided; optionally, multiple second guide rods 1232 may also be provided at intervals along the length direction of the fixed rod 1231 to improve the sliding stability of the locking frame 1233. Locking brackets 1233 are located on both sides of the fixing rod 1231. The first end of the locking bracket 1233 is located in the mounting groove 1211 and slidably sleeved on the second guide rod 1232. The second end extends out of the mounting groove 1211. The outer wall of the second end of the locking bracket 1233 has a protrusion. The protrusion engages with the snap-fit ​​groove 1221 in the second connecting block 122 to achieve the positioning connection of the first connecting block 121 and the second connecting block 122. A second spring 1234 is located between the fixing rod 1231 and the locking bracket 1233 and is sleeved on the outside of the second guide rod 1232. The two ends of the second spring 1234 abut against the fixing rod 1231 and the locking bracket 1233 respectively to apply an elastic force to the locking bracket 1233 along the mounting groove 1211, thereby driving the locking bracket 1233 to extend out of the mounting groove 1211 and engage with the snap-fit ​​groove 1221.

[0044] When it is necessary to lock the two outer support brackets 11, place the two outer support brackets 11 vertically corresponding to each other, press the two locking brackets 1233 extending outside the mounting groove 1211 to retract them. At this time, the second spring 1234 retracts, so that the width of the retracted locking bracket 1233 is less than the width of the snap-fit ​​groove 1221. Then, move the upper outer support bracket 11 toward the lower outer support bracket 11. At this time, the retracted locking bracket 1233 can be inserted into the snap-fit ​​groove 1221 of the lower second connecting block 122. After that, release the locking bracket 1233, so that the locking bracket 1233 can be reset under the elastic action of the second spring 1234, thereby achieving snap-fit ​​fixation with the snap-fit ​​groove 1221. When it is necessary to open the two outer support brackets 11, simply insert the unlocking tool into the unlocking hole 1222 and press the locking bracket 1233 to make the two locking brackets 1233 retract to a width smaller than the snap-fit ​​groove 1221. At this time, move the locking bracket 1233 upward to release the snap-fit ​​lock between the locking bracket 1233 and the snap-fit ​​groove 1221.

[0045] like Figure 1 As shown, the support mechanism 10 also includes a base plate 13 for supporting and fixing relative to the ground. The base plate 13 is disposed on an outer support block in at least one outer support frame 11. The base plate 13 can increase the contact area between the device and the ground, preventing the device from settling. Preferably, a pin is installed at the bottom of the base plate 13, and the stability of the device can be effectively improved by inserting the pin into the installation site.

[0046] During installation, the outer support frame 11 with base plate 13 is first placed below the pipe, and the base plate 13 is securely fixed to the ground with pins. Then, another outer support frame 11 is placed above the pipe, and the locking pieces 12 on the two outer support frames 11 are aligned. The locking bracket 1233 on the first connecting block 121 is pressed inward and inserted into the snap-fit ​​groove 1221 of the second connecting block 122 before being released, thus locking the two outer support frames 11. The inner wall of the inner support ring 211 of the clamping assembly 20 is then checked to ensure a tight fit with the pipe and to guarantee the vibration damping effect. When disassembly is required, the unlocking tool is inserted into the unlocking hole 1222 of the second connecting block 122 and the locking bracket 1233 is pushed inward, disengaging it from the snap-fit ​​groove 1221. The upper outer support frame 11 is then moved upward to separate the two outer support frames, completing the disassembly of the device. When in use, the pipe support device can be installed at intervals along the length of the pipe according to the laying length of the pipe, providing better positioning and buffering and shock absorption effect for the pipe, ensuring that the pipe is not easy to shake during construction, thereby effectively reducing wear, greatly improving the stability and safety of the pipe, and having high construction efficiency.
