[0001] This utility model relates to the field of pipe connection technology, and in particular to a pipe connection auxiliary device that is easy to disassemble and assemble. Background Technology

[0002] In water conservancy engineering construction, pipelines are indispensable key facilities. Given that water pipelines are often laid over long distances, precise connection and fixing between pipelines becomes a crucial step in the construction process. To ensure accurate connection, specialized connection auxiliary devices are typically used to assist in the pipeline connection operation.

[0003] Currently, the pipe connection auxiliary devices used in water conservancy projects generally rely on a large number of bolts to clamp and fix the pipes. In actual operation, operators need to use a wrench to tighten the bolts one by one to complete the installation. After the pipe welding is completed, the bolts need to be loosened one by one with a wrench before the auxiliary device can be separated from the pipe. The whole operation process is cumbersome and redundant, takes a long time, and affects the construction efficiency. Utility Model Content

[0009] Furthermore, the bottom end of the screw is rotatably connected to the movable clamping plate, and the top of the upper connecting seat is provided with a screw hole. The screw is threaded into the screw hole. When the pipe is placed inside the lower clamping seat, the upper connecting seat is connected to the top of the lower clamping seat. Rotating the two force-bearing rods causes the ends of the force-bearing rods to connect into the force-bearing grooves. Rotating the screw causes the movable clamping plate to move downward, and the upper connecting seat moves upward under the influence of the reverse thrust, so that the movable clamping plate is in close contact with the pipe.

[0010] Furthermore, the support B is slidably connected to the support A, the support A has transverse sliding holes on both sides, and the support B has transverse sliders on both sides, with the transverse sliders slidably connected in the transverse sliding holes.

Rotating the screw causes the movable clamping plate to move downward, and the upper connecting seat moves upward under the influence of the reverse thrust, so that the movable clamping plate is in close contact with the pipe, achieving the effect of clamping and fixing the pipe. This effectively ensures the firmness of the connection between the device and the pipe, and makes disassembly and assembly more convenient.

[0013] In addition, the sliding cooperation between the horizontal slider and the horizontal sliding hole guides the movement of the support B. After the two pipes are fixed inside the two lower clamps, the nut is rotated, which drives the support B to move, reducing the distance between the two lower clamps, so that the ends of the two pipes can be precisely connected together, so that the connection part can be welded and the accuracy of the pipe end connection can be guaranteed.

[0021] In this embodiment of the utility model, the top end of the force-bearing tie rod 5 is rotatably connected to the upper connecting seat 4, the top of the lower clamping seat 3 is provided with a force-bearing groove 32, the bottom end of the force-bearing tie rod 5 is connected to the force-bearing groove 32, the movable clamping plate 6 is slidably connected to the upper connecting seat 4, the upper connecting seat 4 is provided with vertical sliding holes 42 on both sides, the movable clamping plate 6 is provided with vertical sliders 61 on both sides, the vertical sliders 61 are slidably connected to the vertical sliding holes 42, the bottom end of the screw 7 is rotatably connected to the movable clamping plate 6, the top of the upper connecting seat 4 is provided with a screw hole 43, and the screw 7 is threadedly connected to the screw hole 43; Using the above technical solution, when the pipe is placed inside the lower clamp 3, the upper connecting seat 4 is connected to the top of the lower clamp 3. Rotating the two force-bearing rods 5 causes the ends of the force-bearing rods 5 to connect to the force-bearing groove 32. Rotating the screw 7 causes the movable clamp 6 to move downward, and the upper connecting seat 4 moves upward under the influence of the reverse thrust, so that the movable clamp 6 is in close contact with the pipe, which achieves the effect of clamping and fixing the pipe, effectively ensuring the firmness of the connection between the device and the pipe, and making disassembly and assembly more convenient.

[0022] In Example 2, based on Example 1, support B12 is slidably connected to support A11. Support A11 is provided with transverse sliding holes 111 on both sides, and support B12 is provided with transverse sliders 121 on both sides. The transverse sliders 121 are slidably connected to the transverse sliding holes 111. By adopting the above technical solution, the horizontal slider 121 and the horizontal sliding hole 111 slide together to guide the movement of the support B12.

[0023] In this embodiment of the utility model, a stud 112 is provided on the outside of the support A11, and a through hole 122 is provided on the outside of the support B12.

Using the above technical solution, after the two pipes are fixed inside the two lower clamps 3 respectively, the nut 2 is rotated, and the support B12 is moved by the nut 2, which reduces the distance between the two lower clamps 3, so that the ends of the two pipes can be accurately connected together, so that the connection part can be welded and the accuracy of the pipe end connection can be guaranteed.

[0024] The working principle of this embodiment is as follows: First, when the pipe is placed inside the lower clamp 3, the upper connecting seat 4 is connected to the top of the lower clamp 3. Rotating the two tension rods 5 causes the ends of the tension rods 5 to connect to the force groove 32. Rotating the screw 7 causes the movable clamp 6 to move downwards, while the upper connecting seat 4 moves upwards under the influence of the reverse thrust, ensuring close contact between the movable clamp 6 and the pipe, thus clamping and fixing the pipe. Next, rotating the nut 2 causes the support B12 to move, reducing the distance between the two lower clamps 3, allowing the ends of the two pipes to be precisely joined together for welding. After the pipe ends are welded, rotating the screw 7 in the opposite direction causes the movable clamp 6 to move upwards, and the upper connecting seat 4 to move downwards, thus allowing the tension rods 5 to be rotated in the opposite direction. This separates the ends of the tension rods 5 from the force groove 32, thus separating the pipe from the device, making operation simpler.
