Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology, specifically a drainage pipeline support device. Background Technology

[0002] In municipal engineering and underground pipe network construction, the laying and installation of drainage pipes is an indispensable key link. Since drainage pipes are usually buried in underground foundation pits, during the construction process, in order to ensure the accuracy and stability of pipe installation and prevent the pipes from shifting or settling due to external forces, support devices are needed to provide temporary or long-term support for the drainage pipes. With the continuous expansion of urban construction scale, the laying length of drainage pipes and the complexity of the construction environment continue to increase, which puts forward higher requirements for the reliability, convenience and maintainability of drainage pipe support devices.

[0003] Most existing drainage pipe support structures are fixedly installed at the bottom of the foundation pit. After the pipe is installed, these support structures are often difficult to remove from the narrow space of the foundation pit. Removal requires lateral excavation of the foundation pit to allow the support structure at the bottom of the pipe to be moved out. This removal operation is cumbersome and labor-intensive. In addition, the support components attached to the bottom of the pipe are prone to deformation or damage after being subjected to the pressure of the drainage pipe for a long time. Once the support components fail, the stability of the entire support device will be affected, posing a safety hazard. Replacing these damaged support components requires disassembling the entire support device for repair, which is cumbersome and costly. Therefore, developing a drainage pipe support device that is easy to disassemble and maintain in the foundation pit at a low cost has become an urgent problem to be solved in the field of drainage pipe construction. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage pipe support device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage pipe support device, comprising a support base, a support platform fixed above the support base, a lifting mechanism provided inside the support platform, the lifting mechanism comprising a semi-circular positioning plate, the semi-circular positioning plate being rotatably connected to the inner wall of the support platform, a flipping protrusion fixed to the outer arc wall of the semi-circular positioning plate, a support pad being slidably connected inside the semi-circular positioning plate, and an anti-fall top plate for raising the support pad being provided inside the semi-circular positioning plate.

[0006] Preferably, the inner arc wall of the support platform is provided with a flip-out groove, and the flip-out protrusion is slidably connected in the flip-out groove of the support platform.

[0007] Preferably, the inner arc wall of the semi-circular positioning plate is provided with a lifting port, and the support pad is slidably connected in the lifting port.

[0008] Preferably, there is a gap between the semi-circular positioning plate and the bottom of the drainage pipe, and the support pad is attached to the bottom of the drainage pipe.

[0009] Preferably, one end face of the semi-circular positioning plate is provided with a receiving groove, and the receiving groove is connected to the lifting port.

[0010] Preferably, the fall arresting plate is slidably connected in the receiving groove of the semi-circular positioning plate, the fall arresting plate is supported on the bottom of the support pad, the inner arc wall of the fall arresting plate is provided with a clearance groove, the support pad engages with the clearance groove, and a pull handle is fixed on one end face of the fall arresting plate.

[0011] This utility model provides a drainage pipe support device, which has the following advantages compared with the prior art:

[0012] By using the lifting mechanism, the anti-fall top plate can be pulled out during disassembly to allow the support pad to fall and provide unobstructed rotation space. Then, the semi-circular positioning plate can be rotated to detach from the bottom of the drainage pipe. This effectively solves the problem of the traditional support structure located at the bottom of the foundation pit being difficult to remove, greatly improving disassembly efficiency and reducing construction difficulty and time costs.

[0013] With the addition of support pads, a semi-circular positioning plate, and an anti-fall top plate, the support pads fill the gap between the semi-circular positioning plate and the drainage pipe during use, and fit tightly against the bottom of the drainage pipe, providing stable support and ensuring the stability and safety of the drainage pipe during installation and use. The support pads and the semi-circular positioning plate are designed to be separate. When the support pads become deformed or damaged due to long-term support of the drainage pipe, they can be easily removed from the semi-circular positioning plate and replaced, ensuring that the support device always maintains a good supporting effect, extending the overall service life of the device, and reducing maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a drainage pipe support device, including a support base 1, a support platform 2 fixed above the support base 1, a lifting mechanism 3 inside the support platform 2, the lifting mechanism 3 including a semi-circular positioning plate 4, the semi-circular positioning plate 4 being rotatably connected to the inner wall of the support platform 2, a flipping protrusion 7 fixed to the outer arc wall of the semi-circular positioning plate 4, a support pad 5 slidably connected inside the semi-circular positioning plate 4, an anti-fall top plate 6 for raising the support pad 5 inside the semi-circular positioning plate 4, a flipping and removal groove 8 opened on the inner arc wall of the support platform 2, the flipping protrusion 7 being slidably connected in the flipping and removal groove 8 of the support platform 2; the support base 1 and the support platform 2 are stably placed in the drainage pipe installation pit, the anti-fall top plate 6 is accurately embedded in the receiving groove 12 of the semi-circular positioning plate 4, and the support pad 5 is slidably assembled up and down through the lifting port 11 of the semi-circular positioning plate 4, which can not only tightly fill the gap between the semi-circular positioning plate 4 and the drainage pipe, but also provide reliable support for the bottom of the pipe.

[0022] It is worth noting that the inner arc wall of the semi-circular positioning plate 4 is provided with a lifting port 11, and the support pad 5 is slidably connected in the lifting port 11. There is a gap between the semi-circular positioning plate 4 and the bottom of the drainage pipe. The support pad 5 is attached to the bottom of the drainage pipe. One end face of the semi-circular positioning plate 4 is provided with a receiving groove 12, which is connected to the lifting port 11. During the disassembly stage: first, the anti-fall top plate 6 is pulled out horizontally, so that the supporting part of the support pad 5 is separated from the semi-circular positioning plate 4. The support pad 5 then falls into the relief groove 10 of the anti-fall top plate 6. This operation not only releases the support constraint on the drainage pipe, but also releases the rotation space. Then, the semi-circular positioning plate 4 is rotated along the pipe axis. The bottom flipping protrusion 7 can be smoothly rotated out of the flipping removal groove 8 of the support platform 2, completing the disassembly of the semi-circular positioning plate 4 from the bottom of the pipe, and completely solving the pain point of the traditional pit bottom support structure being difficult to disassemble.

[0023] It is worth noting that the anti-fall plate 6 is slidably connected in the receiving groove 12 of the semi-circular positioning plate 4. The anti-fall plate 6 is supported on the bottom of the support pad 5. The inner arc wall of the anti-fall plate 6 is provided with a clearance groove 10. The support pad 5 is engaged with the clearance groove 10. A pull handle 9 is fixed on one end face of the anti-fall plate 6. During maintenance: the support pad 5 and the semi-circular positioning plate 4 adopt a separate design. When the support pad 5 is deformed or worn due to long-term pressure, it can be directly removed and replaced from the semi-circular positioning plate 4. This modular design ensures that the replaced support pad 5 can fit tightly against the pipeline, continuously maintain stable support performance, and effectively extend the service life of the overall support structure.

[0024] This solution has the following working process: Before use, the support base 1 and support platform 2 are supported in the pit where the drainage pipe is installed. The anti-fall plate 6 is inserted into the receiving groove 12 of the semi-circular positioning plate 4, and the support pad 5 is slidably assembled into the lifting port 11 of the semi-circular positioning plate 4. In this way, the support pad 5 can fill the gap between the semi-circular positioning plate 4 and the drainage pipe, and at the same time, the support pad 5 provides support for the bottom of the drainage pipe. During disassembly, the anti-fall plate 6 is first pulled outward, causing the part of the anti-fall plate 6 that partially supports the support pad 5 to move out of the semi-circular positioning plate 4, so that the support pad 5... 5. It falls into the clearance groove 10 of the anti-fall top plate 6, so that the support pad 5 can no longer support the drainage pipe and provide unobstructed rotation clearance. Finally, the semi-circular positioning plate 4 is rotated along the axis of the drainage pipe, so that the flipping protrusion 7 at the bottom of the semi-circular positioning plate 4 is rotated out of the flipping removal groove 8 of the support platform 2. This allows the semi-circular positioning plate 4 to be disassembled from the bottom of the drainage pipe, thereby reducing the trouble of the traditional support structure in the foundation pit at the bottom of the drainage pipe being inconvenient to remove. The support base 1 and the support platform 2 can be made of concrete, have a long service life, and do not need to be removed when the foundation pit is backfilled.

[0025] During use, the support pad 5 and the semi-circular positioning plate 4 are designed to be separate. This way, if the support pad 5 deforms or is damaged due to long-term support of the drainage pipe, it can be removed from the semi-circular positioning plate 4 and replaced to ensure that the support pad 5 fits tightly against the drainage pipe and achieves a good support effect.
