Technical Field

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

[0002] Municipal pipelines mainly transport and distribute finished water that meets user requirements to various users. Water transmission pipelines generally have three types: gravity water transmission system, pressure water transmission system, and a combination of gravity and pressure water transmission system. Water distribution networks have two layout forms: tree network and ring network. According to the function of each pipe section in the water distribution network, the water distribution network can be divided into water distribution main pipe, water distribution branch pipe, connecting pipe and distribution pipe. Valve wells, fire hydrants and supports and other auxiliary structures should be set at appropriate locations in the network.

[0003] Currently, in existing technologies, when supporting municipal pipelines, there is a certain gap between the support and the pipeline due to manufacturing process issues. This causes the pipeline's centerline to deviate, resulting in the pipeline not being able to connect properly, making pipeline connection inconvenient. Therefore, there is a need to propose a new type of municipal pipeline support. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the inability of existing municipal pipeline support seats to ensure alignment of the pipeline's centerline, which leads to inconvenience in pipeline connection, this utility model proposes a municipal pipeline.

The centerline positioning mechanism includes a clamping plate disposed in the inner cavity of the fixed seat. One end of the clamping plate extends into the interior of the lower support seat. A slider is disposed at the bottom of the clamping plate and is slidably connected to the inner cavity of the fixed seat. A crossbar is fixedly connected to the opposite side of the slider. A nut is disposed in the middle of the outer wall of the crossbar. A double-threaded rod is threadedly connected to the inner cavity of the nut. The double-threaded rod passes through both sides of the crossbar and is rotatably connected to the crossbar.

[0006] Preferably, the top of the positioning rod is provided with a positioning groove, a positioning block is fixedly connected inside the positioning groove, and the base plate is fixedly connected to the top of the positioning block.

[0007] Preferably, both ends of the upper support are threaded with positioning screws, and the positioning screws pass through the ends of the lower support.

[0008] Preferably, a through groove is provided on one side of the fixed base, the through groove extends into the interior of the lower support base, and the clamping plate is slidably connected inside the through groove.

[0009] Preferably, a guide rail is fixedly connected to the bottom of the through groove, and the guide rail passes through both sides of the slider and is slidably connected to the slider.

[0010] Preferably, the opposite side of the fixed base is provided with a side groove, the side groove is connected to the through groove, and the end of the crossbar passes through the side groove and is slidably connected to the side groove.

[0011] Preferably, a fixing sleeve is fixedly connected to the top of the base plate, the double threaded rod is rotatably connected to the inner cavity of the fixing sleeve, and a turntable is fixedly connected to one end of the double threaded rod.

[0012] The advantages of this utility model are: This invention uses a pre-set positioning and base plate for pre-positioning, allowing the pipe to pass between two sets of lower and upper support seats, thus stabilizing the pipe's centerline. A double-threaded rod drives two crossbars to move relative to each other, causing the crossbars to move a slider within a fixed seat. The slider's movement also causes the clamping plates to move closer together, positioning and clamping the pipe. This ensures the pipe's centerline remains aligned, improving the accuracy of pipe connection and solving the problem of existing municipal pipe support seats failing to guarantee centerline alignment, leading to inconvenient pipe connection.

A centerline positioning mechanism 3 is provided in the inner cavity of the fixed seat 21. By pre-setting two sets of parallel positioning rods 1, the positioning rods 1 and the base plate 2 are pre-aligned to guide the pipeline through the two sets of lower support seats 22. The upper support seat 23 is used to fix the pipeline in conjunction with the lower support seat 22. According to the principle of two points and one line, the centerline of the pipeline is kept parallel to the positioning rod 1. The centerline positioning mechanism 3 in the fixed seat 21 is used to position and clamp the pipeline, so as to reduce the impact of the gap between the pipeline and the upper support seat 23 and the lower support seat 22 on the centerline of the pipeline, thereby achieving the purpose of improving the accuracy of pipeline connection. The centerline positioning mechanism 3 includes a clamping plate 31, which is disposed in the inner cavity of the fixed seat 21. One end of the clamping plate 31 extends into the interior of the lower support seat 22. A slider 32 is disposed at the bottom of the clamping plate 31 and is slidably connected to the inner cavity of the fixed seat 21. A crossbar 33 is fixedly connected to the opposite side of the slider 32. A nut 39 is disposed in the middle of the outer wall of the crossbar 33. A double-threaded rod 34 is threadedly connected to the inner cavity of the nut 39. The double-threaded rod 34 passes through both sides of the crossbar 33 and is rotatably connected to the crossbar 33. By rotating the double-threaded rod 34, the double-threaded rod 34, in conjunction with the nut 39, drives the two sets of crossbars 33 to move relative to each other. The crossbar 33 moves and drives the slider 32 to move. The slider 32 moves and drives the clamping plate 31 to move. The two sets of clamping plates 31, together with the upper support seat 23 and the lower support seat 22, position and clamp the pipe, so that the centerline of the pipe can be kept stably parallel to the positioning rod 1, thereby improving the accuracy of pipe docking.

[0018] Reference Figure 1 and Figure 2 The top of the positioning rod 1 has a positioning groove 11, and a positioning block 12 is fixedly connected inside the positioning groove 11. The bottom plate 2 is fixedly connected to the top of the positioning block 12. The two ends of the upper support seat 23 are threaded with positioning screws 24, and the positioning screws 24 pass through the ends of the lower support seat 22. By using the two pre-set parallel positioning rods 1, the bottom plate 2 is fixed by the four positioning blocks 12 in the positioning groove 11, so that the bottom plate 2 and the positioning rods 1 maintain a stable parallel state. The pipe passes between the two lower support seats 22, and the positioning screws 24 lock the lower support and the upper support seat 23. According to the principle of two points in a line, the pipe can remain parallel to the positioning rod 1, thereby achieving the purpose of improving the accuracy of pipe docking.

[0019] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 A through groove 35 is provided on one side of the fixed base 21, extending into the interior of the lower support base 22. A clamping plate 31 is slidably connected to the interior of the through groove 35. A guide rail 310 is fixedly connected to the bottom of the through groove 35, passing through both sides of the slider 32 and slidably connected to it. A side groove 36 is provided on the opposite side of the fixed base 21, communicating with the through groove 35. The end of the crossbar 33 passes through the side groove 36 and is slidably connected to it. A fixed sleeve 38 is fixedly connected to the top of the base plate 2. A double-threaded rod 34 is rotatably connected to the inner cavity of the fixed sleeve 38. A turntable 37 is fixedly connected to one end of the double-threaded rod 34. The rotating turntable 37 drives the double threaded rod 34 to rotate. The double threaded rod 34 rotates stably within the fixed sleeve 38 at the top of the base. The double threaded rod 34, in conjunction with the nut 39, drives the two crossbars 33 to move relative to each other. The crossbars 33 move through the side groove 36 and drive the slider 32 to move. The slider 32 slides stably in conjunction with the guide rail 310. The movement of the slider 32 drives the clamping plate 31 to move. The clamping plate 31 moves within the through groove 35 and positions and clamps the pipe to reduce the impact of the gap between the pipe and the upper support seat 23 and the lower support seat 22 on the pipe centerline, thereby further improving the accuracy of pipe connection.

[0020] Working principle: In use, the two sets of positioning rods 1 are pre-set in parallel. The base plate 2 is fixed by the four positioning blocks 12 in the positioning groove 11, so that the base plate 2 and the positioning rods 1 are kept parallel. The municipal pipeline passes through the two sets of lower support seats 22, and the upper support seat 23 and the lower support seat 22 are locked together by the positioning screws 24. According to the principle of two points in a line, the pipeline can remain parallel to the positioning rods 1. The center line positioning mechanism 3 in the fixed seat 21 clamps the pipeline to reduce the gap between the upper support seat 23, the lower support seat 22 and the pipeline. The impact of the gap on the pipe centerline is addressed by rotating the turntable 37 to drive the double threaded rod 34 to rotate. The double threaded rod 34, in conjunction with the fixed sleeve 38, rotates stably on the base plate 2. The double threaded rod 34, in conjunction with the nut 39, drives the crossbar 33 to move. The crossbar 33 moves through the side groove 36 and drives the slider 32 to move. The slider 32, in conjunction with the guide rail 310, slides stably and drives the clamping plate 31 to slide relative to each other within the through groove 35. The clamping plates 31 on both sides clamp the pipe inward, keeping the pipe centerline stable, thereby improving the accuracy of pipe connection.
