Description

Technical Field

[0001] This invention relates to the field of pipeline construction technology in water conservancy projects, specifically to a pipeline laying device for water conservancy construction. Background Technology

[0002] In the process of laying pipelines in water conservancy construction, the first step is to lay out the lines, followed by the excavation of the trench. After the trench is excavated, pipe supports need to be installed in the trench. The pipe supports are then used to connect and lay the pipelines into the trench. Finally, a water pressure test is conducted on the pipeline, and the trench is backfilled.

[0003] During pipeline laying, adjacent pipelines need to be connected using a pipeline docking device. Due to the limited space in the trench, workers need to lie on the bottom of the trench to install the pipeline docking device in the designated position. After the connection is completed, they need to lie on the bottom of the trench again to remove the pipeline docking device. This method has low installation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a pipeline laying device for water conservancy construction to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a water conservancy construction pipeline laying device, comprising two support plates, each support plate having a first through hole for a pipeline to pass through, the support plate being divided into upper and lower halves from the first through hole, the upper and lower halves of the support plate being connected by a snap-fit ​​method; a pipeline passes through the first through hole of each of the two support plates; a support beam is connected to each of the two support plates on opposite sides, a U-shaped plate is installed between the two support beams, the U-shaped plate having an opening facing downwards, a second through hole being provided at each end of the U-shaped plate, and two pipelines passing through the second through holes, such that the joint of the two pipelines is located inside the two U-shaped plates.

[0006] Furthermore, it also includes a heating plate, which is installed inside the U-shaped plate. The heating plate is used to heat and connect the joint of the two pipes. Multiple clamps are installed on the heating plate to hold the two pipes together.

[0007] Furthermore, the two support plates are a left support plate and a right support plate, and the two support beams are a left support beam and a right support beam. Each of the two support plates has a support beam connected to its opposite side. Specifically, both the left and right support plates have annular grooves on their opposite sides, located outside the first through hole and coaxially aligned with it. Cylinders are installed at both ends of the left and right support beams. The two cylinders of the left support beam are slidably connected to the annular groove of the left support plate, and the two cylinders of the right support beam are slidably connected to the annular groove of the right support plate, allowing the left and right support beams and the U-shaped plate to rotate. A fixing assembly is also included to fix the rotation angle of the U-shaped plate.

[0008] Furthermore, the fixing component is a plug rod, and the left support plate and the right support plate are respectively provided with through holes, and each of the two through holes is provided with a slidable plug rod. The two ends of the plug rod are pointed and used to insert into the soil to complete the fixing.

[0009] Furthermore, the specific structure of the U-shaped plate installed between the two support beams is as follows: Slide grooves are provided on opposite sides of both the left and right support beams, with the slide groove on the left support beam being the left slide groove and the slide groove on the right support beam being the right slide groove; it also includes a first U-shaped frame, a second U-shaped frame, and sliders. Sliders are connected to the left and right ends of both the first and second U-shaped frames. The left and right ends of the first U-shaped frame are connected to the first slider, and the left and right ends of the second U-shaped frame are connected to the second slider; the first slider at the left end of the first U-shaped frame is slidably connected to the left slide groove, and the first slider at the right end of the first U-shaped frame is slidably connected to the right slide groove; the second U-shaped frame… The second slider at the left end of the frame is slidably connected to the left slide groove, and the second slider at the right end of the second U-shaped frame is slidably connected to the right slide groove. The first U-shaped frame and the second U-shaped frame are arranged opposite to each other. The first U-shaped frame and the second U-shaped frame are respectively installed inside the first U-shaped frame and the second U-shaped frame. The first U-shaped frame and the second U-shaped frame are arranged opposite to each other, and there are gaps at the left and right ends of the first U-shaped frame and the second U-shaped frame. When the first U-shaped frame and the second U-shaped frame slide together, the first U-shaped frame and the second U-shaped frame abut against each other. The U-shaped plate is located on the top of the first U-shaped frame and the second U-shaped frame, and the left and right ends of the U-shaped plate pass through the gaps at the left and right ends of the first U-shaped frame and the second U-shaped frame, respectively.

[0010] Furthermore, the left support beam has an internal mounting cavity, and a cam is installed inside the mounting cavity. The lower end of the cam is connected to a rotating shaft, which extends to the outside of the left support beam. There are two insert rods inside the left support beam, and the two insert rods abut against the front and rear sides of the cam respectively. Rotating the cam can squeeze the two insert rods and push them outward. The right support beam also has a cam and a rotating shaft, which are symmetrically arranged with the left support beam.

[0011] Furthermore, the left support beam is also provided with a guide hole, the direction of which is the same as the axial direction of the pipe; a slidable guide rod is connected to the guide hole, and a clearance opening is provided in the guide rod. The upper end of the cam is connected to an elliptical ring through a connecting rod. The elliptical ring is located in the clearance opening, and the guide rod abuts against the elliptical ring. Rotating the elliptical ring can squeeze the guide rod to push it outward; one end of the guide rod is fixedly connected to an arc plate through a hanging plate; the right support beam has the same structure as the left support beam.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention includes two support plates, which clamp and stably support two pipes in the trench, so that the pipe ends of the two pipes are stably connected. Workers need to use existing pipe connection devices to weld the pipe ends of the two pipes. After welding, both support plates of the present invention can be disassembled into upper and lower halves, which is efficient and easy to remove in the trench.

[0013] 2. The left and right support plates are respectively equipped with annular grooves, cylinders, and other structures, allowing the U-shaped plate to rotate along the annular grooves. The heating plate is installed on the U-shaped plate, and by rotating the U-shaped plate, the heating plate can heat and weld the two pipe openings from all directions, improving heating efficiency. This eliminates the need for workers to hold the heating plate and move it to different angles on the two pipe openings for heating and welding, reducing labor consumption and improving welding efficiency.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, so as to provide a better understanding of the concept of the present invention, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about.

[0026] like Figures 1-4 , Figure 6 , Figure 8 As shown, a hydraulic construction pipeline laying device includes two support plates 1. Each support plate 1 has a first through hole for a pipe 100 to pass through. The support plate 1 is divided into upper and lower halves from the first through hole, and the upper and lower halves of the support plate 1 are connected by a snap-fit ​​method. A pipe 100 passes through the first through hole of each of the two support plates 1. A support beam 2 is connected to each of the two support plates 1 on opposite sides. A U-shaped plate 6 is installed between the two support beams 2. The opening of the U-shaped plate 6 faces downward. A second through hole is provided at each end of the U-shaped plate 6. The two pipes 100 pass through the second through holes, so that the joint of the two pipes 100 is located inside the two U-shaped plates 6.

[0027] During the docking process of two pipes 100, the pipe ends of the two pipes 100 need to be aligned and pressed together. A pipe docking device (existing technology, since the pipes 100 to be docked are usually PE pipes, the pipe docking device is usually a heating plate 61, and the PE pipe docking device disclosed in CN212603525U or CN215589971U can be used) is used to heat and weld the pipe ends of the two pipes 100. During the docking process, the pipe docking device needs to rotate around the circumference of the pipe ends of the two pipes 100. Due to the narrow space of the groove, rotation is inconvenient. The present invention includes two support plates 1, which clamp and stably support the two pipes 100 in the groove, so that the pipe ends of the two pipes 100 are stably docked. In this embodiment, workers need to use existing pipe connection devices to weld the two pipes 100 at their openings. After welding, the two support beams 2 of this invention can be disassembled into upper and lower halves, which is efficient and easy to remove in the trench.

[0028] Furthermore, a heating plate 61 is also included, which is installed inside the U-shaped plate 6. The heating plate 61 is used to heat and weld the joint of the two pipes 100. In this embodiment, the manual welding of the prior art is replaced by welding with the heating plate 61 installed inside the U-shaped plate 6.

[0029] Furthermore, the two support plates 1 are the left support plate and the right support plate, and the two support beams 2 are the left support beam and the right support beam, respectively. A support beam 2 is connected to each of the opposite sides of the two support plates 1. Specifically, an annular groove 7 is provided on the opposite side of both the left and right support plates. The annular groove 7 is located outside the first through hole and is coaxially arranged with the first through hole. Cylinders 8 are installed on both the left and right ends of the left and right support beams. The two cylinders 8 of the left support beam are slidably connected to the annular groove 7 of the left support plate, and the two cylinders 8 of the right support beam are slidably connected to the annular groove 7 of the right support plate, allowing the left support beam, the right support beam, and the U-shaped plate 6 to rotate. A fixing component is also included, which is used to fix the rotation angle of the U-shaped plate 6.

[0030] The left and right support plates are respectively equipped with annular grooves 7 and cylinders 8, which allow the U-shaped plate 6 to rotate along the annular grooves 7. The welding heating plate 61 is installed on the U-shaped plate 6. By rotating the U-shaped plate 6, the two pipe openings of the heating plate 61 are heated and welded from all directions, improving heating efficiency. This eliminates the need for workers to hold the heating plate 61 and move it to different angles of the two pipe openings 100 for heating and welding, reducing labor costs and improving welding efficiency.

[0031] Furthermore, the fixing component is a plug rod 22. The left and right support plates each have through holes, and a slidable plug rod 22 is installed in each of the two through holes. Both ends of the plug rod 22 are pointed and used to insert into the soil to complete the fixing. After the heating and welding are completed, it is necessary to wait for the openings of the two pipes 100 to form. During this process, the openings of the two pipes 100 are easily affected. By rotating the U-shaped plate 6 above the two pipes 100 and inserting the plug rod 22 into the side wall of the trench, the U-shaped plate 6 can be stably positioned above the two pipes 100, preventing falling objects (stones, soil, etc. above the trench) from causing damage.

[0032] like Figure 7 As shown, further, the specific structure of the U-shaped plate 6 installed between the two support beams 2 is as follows: A sliding groove 21 is provided on the opposite side of both the left and right support beams; the sliding groove 21 of the left support beam is the left sliding groove, and the sliding groove 21 of the right support beam is the right sliding groove. It also includes a first U-shaped frame 3, a second U-shaped frame 4, and sliders 5. Sliders 5 are connected to the left and right ends of the first U-shaped frame 3 and the second U-shaped frame 4. The left and right ends of the first U-shaped frame 3 are connected to the first slider, and the left and right ends of the second U-shaped frame 4 are connected to the second slider. The first slider at the left end of the first U-shaped frame 3 is slidably connected to the left sliding groove, and the first slider at the right end of the first U-shaped frame 3 is slidably connected to the right sliding groove. The left end of the second U-shaped frame 4... The second slider is slidably connected to the left slide groove, and the second slider at the right end of the second U-shaped frame 4 is slidably connected to the right slide groove. The first U-shaped frame 3 and the second U-shaped frame 4 are arranged opposite to each other. The first U-shaped frame 31 and the second U-shaped frame 41 are respectively installed inside the first U-shaped frame 3 and the second U-shaped frame 4, which are arranged opposite to each other, and gaps are left at the left and right ends of the first U-shaped frame 3 and the second U-shaped frame 4. When the first U-shaped frame 3 and the second U-shaped frame 4 slide together, the first U-shaped frame 31 and the second U-shaped frame 41 abut against each other. The U-shaped plate 6 is located on the top of the first U-shaped frame 3 and the second U-shaped frame 4, and the left and right ends of the U-shaped plate 6 pass through the gaps at the left and right ends of the first U-shaped frame 3 and the second U-shaped frame 4, respectively. The left and right slide grooves are provided so that the first U-shaped frame 3 and the second U-shaped frame 4 can be opened or closed along the direction of the left and right slide grooves, and the first U-shaped frame 3 and the second U-shaped frame 4 are provided with protrusions and grooves for snap-fit ​​connection. The heating plate 61 is U-shaped. After passing through the gap between the first U-shaped frame 3 and the second U-shaped frame 4, the heating plate 61 is connected to the two pipes 100 by its own clamp 62. It can rotate around the circumference of the two pipes 100, which facilitates the heating and welding of the pipe openings of the two pipes 100.

[0033] Furthermore, the left support beam has an internal mounting cavity containing a cam 9. The lower end of the cam 9 is connected to a rotating shaft 10, which extends outwards from the left support beam. Two insertion rods 22 are located within the left support beam, respectively abutting the front and rear sides of the cam 9. Rotating the cam 9 compresses the two insertion rods 22, causing them to push outwards. The right support beam also contains a cam 9 and a rotating shaft 10, symmetrically arranged with the left support beam. The cam 9, connected to the rotating shaft 10, rotates the cam 9. As the cam 9 rotates, its distance from the rotating shaft 10 varies at different angles. The portion of the cam 9 furthest from the rotating shaft 10 compresses the insertion rods 22, causing them to push outwards and insert into the sidewall of the trench, thus fixing the left and right support beams relative to the trench.

[0034] like Figure 5 , Figure 9 , Figure 10As shown, furthermore, the left support beam is provided with a guide hole 11, the direction of which is the same as the axial direction of the pipe 100; a slidable guide rod 12 is connected inside the guide hole 11, and a clearance opening 121 is provided inside the guide rod 12. The upper end of the cam 9 is connected to an elliptical ring 13 through a connecting rod. The elliptical ring 13 is located inside the clearance opening 121. The guide rod 12 abuts against the elliptical ring 13. Rotating the elliptical ring 13 can squeeze the guide rod 12, causing the guide rod 12 to be pushed outward; one end of the guide rod 12 is fixedly connected to an arc plate 15 through a hanging plate 14; the right support beam has the same structure as the left support beam. A reinforcing ring 200 is fixedly connected to the pipe 100. The reinforcing ring 200 is fixed by adhesive or welding. The reinforcing ring 200 is installed before the pipe 100 is lowered into the trench. The reinforcing ring 200 is set correspondingly to the arc plate 15. In the initial state, the arc plate 15 does not contact the reinforcing ring 200. In this way, when the pipe 100 is laid, as the left and right support beams rotate, the arc plate 15 will not have any impact on the pipe 100. At the same time, the guide rod 12 is provided with a clearance opening 121. A cam 9 is provided in the clearance opening 121. When the cam 9 rotates, it allows the guide rod 12 to slide in the guide hole 11. When the insertion rod 22 extends from the relief opening 121 and inserts into the positioning hole on the side wall of the pipe 100 groove, the guide rod 12 also retracts inward, causing the arc plate 15 to translate and contact the reinforcing ring 200. The arc plates 15 on both sides reinforce the two reinforcing rings 200, thus improving the tensile strength of the pipe 100. To facilitate the rotation of the cam 9 and the elliptical ring 13, through holes are provided at the top of the left and right support beams. A rotating shaft 10 is rotatably connected in the through holes, and the rotating shaft 10 is fixedly connected to both the cam 9 and the elliptical ring 13. During the rotation of the rotating shaft 10, the cam 9 and the elliptical ring 13 can rotate simultaneously. In addition, to prevent the guide rod 12 and the insertion rod 22 from moving during rotation, dampers are provided between the insertion rod 22 and the relief opening 121, and between the guide rod 12 and the guide hole 11.
