Description

Technical Field

[0001] The utility model relates to the technical field of pipeline butt joint devices, in particular to a pipeline butt joint device. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects need to build dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. The most commonly used in water conservancy projects are water pipelines. Due to the limited production length of water pipelines, they need to be docked and installed during the construction of water conservancy projects.

[0003] In order to facilitate the docking and installation of water conservancy projects, the prior art has made many improvements to the pipe docking device for water conservancy projects, such as the patent publication number CN220074455U, which discloses a water conservancy pipeline auxiliary docking device, including a mounting plate and a support seat, the interior of the mounting plate is provided with a placement groove, the inner top wall of the placement groove is provided with a storage groove, the inner side wall of the storage groove is provided with a first slide groove, the inner bottom wall of the first slide groove is fixedly connected with a fixing rod, the outer wall of the fixing rod is slidably connected with a connecting block, one side of the connecting block is fixedly connected with a connecting plate, the bottom of the connecting plate is fixedly connected with an extrusion plate, the top of the connecting plate is fixedly connected with a connecting column, the outside of the connecting column is provided with a second slide groove, and the inner top wall of the storage groove is provided with an empty groove. The utility model can facilitate the extrusion and fixing of pipes of different diameters to be docked to prevent deviation, facilitate people to fix the pipes to be docked for easy splicing, save a lot of manpower and material resources, and improve the use stability of the docking device.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, the water conservancy pipe is passed through the placement grooves on the two mounting plates, and the water conservancy pipe is squeezed by the extrusion plate, so as to align the ends of the two water conservancy pipes. However, in reality, if the docking device in the above-mentioned comparative document is used to dock the water conservancy pipes on site, the water conservancy pipe to be installed needs to be passed through the mounting plates. After the water conservancy pipe is installed, the device needs to be taken out along the water conservancy pipe. If the water conservancy pipe is long, it is more troublesome to take out the docking device. Therefore, there is an urgent need to improve the pipe docking device in this field to solve the defects of the prior art. Summary of the Invention

When installing, the installer clamps the bearing frame 3 at the ends where the two water conservancy pipelines 1 need to be connected. By rotating the first adjusting rod 7, the first adjusting rod 7 drives the clamping frame 5 to move towards the installation flange 2. The clamping frame 5 is arc - shaped. The two installation flanges 2 are extruded through the extrusion bevels 6 until the side surfaces of the two installation flanges 2 are in contact with the two extrusion bevels 6, and through the extrusion of the extrusion bevels 6, the two installation flanges 2 approach and are close to each other. Subsequently, the two water conservancy pipelines 1 are rotated through the rotating unit 8 so that the positions of the installation holes on the two installation flanges 2 are aligned, and bolts are passed through the installation holes exposed outside to position the installation flanges 2. Then, the first adjusting rod 7 is rotated in the reverse direction, the rotating unit 8 is released, the bearing frame 3 is removed, and bolts are continued to be installed in other installation holes to complete the connection installation between the two water conservancy pipelines 1, which is convenient for the installer to perform deviation - correcting installation on the water conservancy pipelines 1.
