Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and in particular to an anti-collapse device for municipal water supply and drainage construction. Background Technology

[0002] In urban water supply projects, water is typically transported via underground buried pipelines. During backfilling, anti-collapse devices are required to ensure pipeline safety. However, existing anti-collapse devices have several problems. First, installation is inconvenient. Second, most devices only provide protection above the pipeline, failing to effectively protect pipe joints, potentially leading to deformation or leakage under stress. Furthermore, existing devices lack cushioning; under significant impact, the top protective plate easily deforms, causing pipe misalignment and affecting the long-term stability of the pipeline connection. Additionally, these devices are typically only compatible with specific pipe models, limiting their applicability. Utility Model Content

[0003] The main purpose of this utility model is to provide an anti-collapse device for municipal water supply and drainage construction, which aims to improve the adaptability, safety and long-term stability of the pipeline connection.

[0004] To achieve the above objectives, this utility model proposes an anti-collapse device for municipal water supply and drainage construction, comprising:

[0005] Two sets of support frames, each set consisting of two support frames, with a receiving block hinged between the upper ends of the two support frames, a limit frame hinged on each support frame, and a telescopic column hinged between each limit frame and the support frame, with both the support frame and the limit frame abutting against the outer wall of the pipe.

[0006] A limiting component is disposed on the receiving block and is used to limit the included angle between the two support frames.

[0007] In one possible implementation, the limiting component includes a limiting seat rotatably connected to a receiving block, an adjusting handle threadedly connected to the limiting seat, a transmission plate rotatably connected to the lower end of the adjusting handle, a snap-fit ​​plate elastically telescopically connected to the transmission plate, and the snap-fit ​​plate snapping into the support frames on both sides of the plate.

[0008] In one possible implementation, two limiting posts are fixedly connected to the transmission plate, and the snap-fit ​​plate is slidably connected to the two limiting posts. Each limiting post is fitted with a limiting spring, and the two ends of the limiting spring abut against the transmission plate and the snap-fit ​​plate, respectively.

[0009] In one possible implementation, each of the support frames is provided with a snap-fit ​​groove, and snap-fit ​​blocks are fixedly connected to both ends of the snap-fit ​​plate, with each snap-fit ​​block abutting against the inner wall of the adjacent snap-fit ​​groove.

[0010] In one possible implementation, each of the transmission plates is fixedly connected to a limiting cylinder at its lower end, and two limiting sleeves are slidably connected to the limiting cylinders, with the limiting sleeves abutting against the outer wall of the tube.

[0011] In one possible implementation, the limiting sleeve has a corrugated shape.

[0012] In one possible implementation, the outer ring of the limiting sleeve is fitted and fixedly connected to a first covering sleeve, and both sides of the first covering sleeve are fitted and fixedly connected to a second covering sleeve.

[0013] This utility model's technical solution, through the design of two sets of support frames and limiting frames, effectively limits and supports the pipe connection, preventing misalignment caused by uneven joint pressure during backfilling. The support frames maintain pipe stability, reducing the risk of misalignment, while the limiting frames strengthen the support on the lower side of the pipe, improving the stability of the connection and preventing the pipe from shifting or deforming under external forces. Furthermore, in conjunction with the limiting components, the support frames can precisely limit the movement of pipes with different outer diameters, ensuring that adjustments do not directly contact the pipe's outer wall, avoiding damage. The overall design improves the product's adaptability, safety, and long-term stability of the pipe connection. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] This utility model proposes an anti-collapse device for municipal water supply and drainage construction.

[0024] Reference Figures 1 to 4 ,include:

[0025] Two sets of support frames 11, each set of support frames 11 consists of two, and a receiving block 12 is hinged between the upper ends of the two support frames 11. A limit frame 13 is hinged on each support frame 11, and a telescopic column 14 is hinged between each limit frame 13 and the support frame 11. Both the support frame 11 and the limit frame 13 abut against the outer wall of the pipe.

[0026] A limiting component is provided on the receiving block 12 to limit the included angle between the two support frames 11;

[0027] By setting two sets of support frames 11, after the two pipes are connected, the support frames 11 can provide effective limiting at the connection point. This design can prevent pipe misalignment due to uneven pressure at the pipe joint during backfilling, thus ensuring the stability of the pipe connection. The support frames 11, by supporting both sides of the pipe, ensure that the pipe's position remains unchanged during backfilling and use, reducing the risk of misalignment. In addition, the limiting frame 13 further limits the lower area of ​​the pipe, ensuring stable support below the pipe. This additional limiting effect enhances the stability of the pipe connection, preventing the pipe from shifting or deforming under stress or external interference. The synergistic effect of the two sets of support frames and the limiting frame provides all-round support, ensuring the reliability of the pipe connection and long-term stable operation. Furthermore, in conjunction with the upper limiting component, the support frame 11 can adapt to pipes of different outer diameters, achieving precise limiting, thereby improving the product's applicability and flexibility, and ensuring that the two support frames do not directly contact the outer wall of the pipe when adjusting the support frame angle, avoiding compression and damage to the outer wall of the pipe caused by improper operation. This not only improves product compatibility and operational safety, but also ensures the stability and integrity of the pipeline during use.

[0028] Reference Figures 1 to 4 The limiting component includes a limiting seat 21, which is rotatably connected to the receiving block 12. An adjusting handle 22 is threadedly connected to the limiting seat 21. A transmission plate 23 is rotatably connected to the lower end of the adjusting handle 22. A snap-fit ​​plate 24 is elastically telescopically connected to the transmission plate 23. The two sides of the snap-fit ​​plate 24 are snapped into the support frame 11 on both sides respectively.

[0029] By adjusting the handle 22 in the limiting assembly, the operator can control the distance between the transmission plate 23 and the receiving block 12, thereby adjusting the angle of the two support frames 11. This design allows the support frames 11 to adapt to pipes of different outer diameters, achieving precise limiting and improving the product's applicability and flexibility. During adjustment, the elastically telescopically connected snap-fit ​​plate 24 connects to the support frames 11 on both sides, further adjusting the angle between the two support frames 11 through elastic telescopic action. This design ensures that the support frames on both sides do not directly contact the outer wall of the pipe when adjusting the support frame angle, avoiding squeezing and damage to the outer wall of the pipe caused by improper operation. In this way, the support frames 11 can make more gentle contact with the pipe surface when adapting to the pipe, effectively preventing the pipe from being compressed or deformed due to improper external operation. Overall, this design not only improves the product's adaptability and operational safety but also ensures the stability and integrity of the pipe during use.

[0030] Reference Figures 2 to 4Two limiting posts 25 are fixedly connected to the transmission plate 23, and the snap-fit ​​plate 24 is slidably connected to the two limiting posts 25. Each limiting post 25 is fitted with a limiting spring 26, and the two ends of the limiting spring 26 abut against the transmission plate 23 and the snap-fit ​​plate 24 respectively.

[0031] The angle adjustment between the two support frames 11 is controlled by the spring force through the design of the limiting spring 26. When the angle between the two support frames 11 is adjusted, the limiting spring 26 provides appropriate elasticity, ensuring that the force is evenly distributed during the adjustment process and preventing the support frames 11 from directly acting on the outer wall of the pipe. This effectively prevents cracks or other damage to the outer wall of the pipe caused by improper operation. The limiting spring 26 not only smooths the force of angle adjustment but also ensures a gentler contact between the pipe and the support frame, reducing the impact on the pipe. Through this design, operators can flexibly adjust the angle between the support frames 11 according to different installation requirements, thereby improving the adaptability of the support frames and the pipe and ensuring that the support frames can be better used with pipes of different sizes and shapes. The introduction of the limiting spring 26 optimizes the interaction between the support frames and the pipe, making the adjustment process safer and smoother, while improving the product's adaptability and pipe protection effect, and avoiding pipe damage caused by improper operation.

[0032] Reference Figures 1 to 2 Each support frame 11 is provided with a snap-fit ​​groove 111, and snap-fit ​​blocks 27 are fixedly connected to both ends of the snap-fit ​​plate 24. Each snap-fit ​​block 27 abuts against the inner wall of the adjacent snap-fit ​​groove 111.

[0033] Through the contact relationship between the snap-fit ​​block 27 and the inner wall of the snap-fit ​​groove 111 on each support frame 11, the snap-fit ​​plate 24 can slide under the drive of the adjusting handle 22, thereby adjusting and limiting the angle between the two support frames 11. This design allows the support frame 11 to be precisely adjusted according to the specific shape and position of the pipeline, ensuring better fit and support with the outer wall of the pipeline. When the support frame 11 is tightly fitted with the outer wall of the pipeline, it can effectively limit the pipeline and prevent the pipeline from shifting due to sand pressure or external load. This tight support and limiting effect not only enhances the stability of the pipeline, but also improves the connection between pipelines, making the entire pipeline system more stable and reliable. In summary, through the synergistic effect of the snap-fit ​​block 27, the snap-fit ​​groove 111, and the adjusting handle 22, the support frame 11 can provide more flexible and precise support and limiting functions, thereby effectively preventing the pipeline from shifting due to external pressure during use and ensuring the safety and stability of the pipeline connection.

[0034] Reference Figures 2 to 4 Each transmission plate 23 is fixedly connected to a limiting cylinder 31 at its lower end, and a limiting sleeve 32 is slidably connected to the two limiting cylinders 31, with the limiting sleeve 32 abutting against the outer wall of the pipe.

[0035] The limiting sleeves 32 are installed by limiting the position of the limiting sleeves 31 on the lower side of each transmission plate 23, which effectively simplifies the installation process. Workers can easily and accurately install the limiting sleeves 32 into the designated positions and ensure that the limited sleeves 32 are firmly fixed after installation to prevent them from coming off during use. This limiting design helps to ensure the alignment of pipe joints, thereby avoiding pipe misalignment or loose joints. In addition, the fixing of the limiting sleeves 32 ensures a tighter connection between the pipe joints on both sides, improving the stability and sealing of the connected pipes. The two sets of support frames 11 further strengthen the fixation of the pipes by limiting and supporting the pipes on both sides, preventing the pipes from shifting or deforming due to external pressure or load.

[0036] Reference Figures 1 to 4 The limiting sleeve 32 has a corrugated shape.

[0037] The corrugated retaining sleeve 32 increases the contact area with sand and gravel, allowing for more effective distribution of pressure and weight when sand and gravel act on it. This enables the retaining sleeve 32 to form a tighter fit with the pipe joint, enhancing the contact force between them and the pipe, preventing concentrated pressure from sand and gravel at the joint, thus reducing damage and deformation. By evenly distributing the pressure of the sand and gravel, the uniform stress at the pipe joint is ensured, effectively preventing misalignment or collapse due to uneven external pressure. Furthermore, the corrugated structure not only increases the contact area but also improves the supporting strength of the retaining sleeve, giving it a stronger load-bearing capacity when facing sand, gravel, and other external pressures, thus providing more reliable protection for the pipeline.

[0038] Reference Figures 3 to 4 The outer ring of the limiting sleeve 32 is fitted and fixedly connected to the first covering sleeve 33, and the two sides of the first covering sleeve 33 are fitted and fixedly connected to the second covering sleeve 34.

[0039] The addition of a first protective sleeve 33 and a second protective sleeve 34 provides protection by adding extra barriers at the pipe joint gaps. The barriers effectively block direct impact from sand, gravel, and other external substances on the pipe joint, preventing misalignment or collapse due to pressure. They also prevent direct damage to the pipe joint from external pressure such as sand and gravel, and strengthen the connection between pipes by dispersing pressure.
