Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline support technology, and in particular to a support device for laying municipal pipelines. Background Technology
[0002] Municipal pipelines, also known as urban underground pipelines, are the pipelines and ancillary facilities for water supply, drainage, electricity, etc. within a city. They are responsible for functions such as information transmission, energy transmission, flood control and disaster reduction, and waste disposal, and are important infrastructure to ensure the operation of the city.
[0003] Municipal pipeline laying typically involves excavating trenches. Different pipelines are laid for different purposes such as water supply and drainage, and electricity. Support devices are usually used to support and pre-embed the pipelines before fixing them together. The support devices used during laying can prevent the pipelines from sagging, deforming, or even breaking due to gravity when they are connected, ensuring that the pipelines remain in the designed position and height and maintain normal operation.
[0004] Pipe supports are usually installed at the bottom of trenches to support the pipes. The bottom of the trenches is usually uneven, and simple four-corner supports can easily cause the pipes to move during laying. At the same time, the pipes cannot be stable when connected. Therefore, a support device for laying municipal pipelines is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a support device for laying municipal pipelines, which aims to improve the problem that pipeline supports in the prior art are prone to movement when supporting pipelines, making it impossible for the pipelines to be stable during connection.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0034] 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.
[0035] Reference Figures 1-4 This utility model provides an embodiment of a support device for laying municipal pipelines, including a support plate 1. The support plate 1 supports the top structure and makes the structure more stable. A connecting plate 2 is fixedly connected to the outside of the support plate 1. A buckle assembly is installed inside the connecting plate 2. A telescopic rod 3 is installed on the outside of the buckle assembly. The buckle assembly fixes the telescopic rod 3 in position. A rotating assembly is installed at the bottom of the telescopic rod 3. A pull rod 10 is fixedly connected to the top of the telescopic rod 3. Pushing the pull rod 10 causes the telescopic rod 3 to move up and down. The rotating assembly includes a connecting block 11, which is rotatably connected to the bottom of the telescopic rod 3. When the pull rod 10 is pressed down, it pushes the telescopic rod 3 down, causing the connecting block 11 to move down and rotate. A rotating block 12 is rotatably connected to the end of the connecting block 11. A fixed block 5 is rotatably connected to the outside of the rotating block 12. The downward-moving connecting block 11 causes the rotating block 12 to rotate and open, forming a hook in the soil to support and stabilize the support plate 1. The telescopic rod 3 is slidably connected inside the fixed block 5. The snap-fit assembly includes a slide rod 6, which is slidably connected inside the connecting plate 2. A spring 9 is fixedly connected to the bottom of the slide rod 6, and the spring 9 compresses the slide rod 6. A slot 4 is provided inside the telescopic rod 3, and the slide rod 6 engages with the slot 4. When the pull rod 10 is pressed down, it pushes the telescopic rod 3 downward. Under the pressure of the spring 9, the slide rod 6 is pressed tightly against the telescopic rod 3. When the telescopic rod 3 moves down to a certain position, the slide rod 6 inserts into the slot 4 to engage, thus fixing the position of the telescopic rod 3 and preventing it from moving upward when the support device supports the pipe, causing the rotating block 12 to retract and making the device unstable. A slider 8 is fixedly connected to the top of the slide rod 6. A groove 7 is provided inside the connecting plate 2, and the slider 8 is slidably connected inside the groove 7. Moving the slider 8 causes the slide rod 6 to retract, and at the same time, pulling the pull rod 10 retracts the rotating block 12.
[0036] Reference Figure 1 , Figure 5 and Figure 6A rotating shaft 14 is rotatably connected to the inner side of the support plate 1. A knob 13 is fixedly connected to the end of the rotating shaft 14. Rotating the knob 13 drives the rotating shaft 14 to rotate. A worm gear 16 is fixedly connected to the end of the rotating shaft 14. The rotating shaft 14 drives the worm gear 16 to rotate. A housing 15 is fixedly connected inside the support plate 1. The housing 15 protects the internal mechanical structure and prevents the external environment from affecting the structure. A screw 18 is rotatably connected inside the housing 15. A worm wheel 17 is fixedly connected to the outer side of the screw 18. The worm wheel 17 meshes with the worm gear 16. The knob 13 drives the rotating shaft 14 to rotate, which in turn drives the worm gear 16 to rotate. The rotating worm gear 16 drives the worm wheel 17 to rotate, thereby rotating the screw 18. A screw 20 is threadedly connected to the outer side of the screw 18. The rotating screw 18 drives the screw 20 to rotate and move up and down. A bearing 19 is fixedly connected to the bottom of the screw 20. The system includes a fixed telescopic leg 21. A screw 20, which moves up and down, drives the telescopic leg 21 to move up and down via a bearing 19. A telescopic leg 23 is slidably connected inside the telescopic leg 21. A bearing 22 is fixedly connected inside the telescopic leg 23. A screw 3 24 is fixedly connected inside the bearing 22. The screw 3 24 is threaded onto the outside of the screw 20. The rotating screw 20 drives the screw 3 24 to rotate and move up and down simultaneously. The moving screw 3 24, via the bearing 22, drives the telescopic leg 23 to slide inside the telescopic leg 21. A telescopic leg 3 25 is threaded onto the outside of the screw 3 24. The rotating screw 3 24 drives the telescopic leg 3 25 to move up and down. A bracket 26 is fixedly connected to the top of the telescopic leg 3 25. The moving telescopic leg 3 25 drives the bracket 26 to move up and down. This system provides support for the pipeline and makes pipeline laying and connection more convenient and faster, improving work efficiency.
[0037] Working principle: First, press down the pull rod 10 to push the telescopic rod 3 downward, which drives the connecting block 11 to move downward and rotate. The end of the connecting block 11 is rotatably connected to the rotating block 12. The downward moving connecting block 11 drives the rotating block 12 to rotate and open, forming a hook in the soil to support and stabilize the support plate 1. At the same time, the sliding rod 6 is pressed tightly against the telescopic rod 3 under the pressure of the spring 9. When the telescopic rod 3 moves down to a certain position, the sliding rod 6 inserts into the slot 4 to lock and fix the position of the telescopic rod 3, preventing the telescopic rod 3 from moving upward when the support device supports the pipeline, causing the rotating block 12 to retract and making the device unstable.
[0038] Then, rotating knob 13 drives shaft 14 to rotate. The rotating shaft 14 drives worm gear 16 to rotate, which in turn drives worm wheel 17 to rotate, thereby causing screw 18 to rotate. Screw 18 rotates and drives screw 20 to rotate and move up and down. Screw 20 moves up and down and drives telescopic leg 21 to move up and down through bearing 19. Screw 20 rotates and drives screw 3 24 to rotate and move up and down. Screw 3 24 moves up and down and drives telescopic leg 2 23 to move up and down through bearing 22. Screw 3 24 rotates and drives telescopic leg 2 25 to move up and down, thereby realizing the up and down adjustment of bracket 26. When supporting pipes, the pipe height can be quickly adjusted, making pipe laying and connection more convenient and faster, and improving work efficiency.
