[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control the flow of water and regulate and distribute the amount of water to meet the needs of people's life and production for water resources. The installation of pipelines can improve the direction of water sources. At the same time, pipeline auxiliary connection devices are required to connect and install pipelines during pipeline installation.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides an auxiliary connection device for a water conservancy project pipeline, comprising a base 1, a pipeline centering device 2, a conveying seat 3 and a conveying motor 4, wherein two pipeline centering devices 2 are fixedly installed on the base 1 in a mirror-symmetrical manner, the pipeline centering device 2 is located on one side of the conveying seat 3, a plurality of conveying seats 3 are fixedly installed on the base 1, and the conveying motor 4 is fixedly installed on the conveying seat 3.

[0022] The pipeline centering device 2 includes a housing 21, a guide body 22, a two-way cylinder 23, a push block 24, a centering rod 25, a spring 26 and a guide groove 27. The housing 21 is fixedly mounted on the base 1; the guide body 22 and the two-way cylinder 23 are fixedly mounted inside the housing 21, and the two ends of the two-way cylinder 23 are respectively fixedly connected to the push block 24 slidably mounted inside the housing 21. The push block 24 and the centering rod 25 are in contact with each other. The centering rod 25 is elastically slidably mounted in the guide groove 27 through the spring 26, and the guide groove 27 is provided on the guide body 22. The pipeline centering device 2 accurately realizes the axial alignment of the pipeline through a four-way correction mechanism, and it also has a clamping and fixing function.

[0023] Embodiment 1:

[0024] Specifically, both the casing 21 and the guide body 22 are provided with through holes for allowing the steel pipe to pass through, which fully considers the convenience and stability of the passage of the pipe. It is not only easy to manufacture and install, but also provides a stable and spacious channel for the pipe. The casing 21 is a rectangular structure, and the guide body 22 is a polygonal structure.

[0025] Specifically, there are two push blocks 24, which are slidably mounted on the upper and inner sides of the housing 21, respectively. The two push blocks 24 adopt a unique "concave"-shaped structural design, and the concave surface of the push blocks 24 just contacts one end of the centering rod 25. This design enables the push blocks 24 to accurately transmit force to the centering rod 25 through their two inclined surfaces when pushed by the bidirectional cylinder, thereby realizing the precise movement of the centering rod 25.

[0026] Specifically, there are four centering rods 25, which are respectively located around the pipeline and can stably and evenly center the pipeline from multiple directions. The end of the centering rod 25 that contacts the push block 24 is an arc-shaped end. The design not only improves the stability of force transmission, but also the arc-shaped end can better fit the inclined surface of the push block 24, thereby ensuring that the push block 24 can accurately and smoothly push the centering rod 25 when moving. The other end of the centering rod 25 passes through the guide body 22 through the guide groove 27. The guide groove 27 provides a sliding path for the centering rod 25, so that it can slide accurately inside the guide body 22 under the push of the push block 24. At the same time, the guide groove 27 also limits the moving direction of the centering rod 25, ensuring that it always remains parallel to the pipeline axis during the movement.

[0027] Specifically, there are four groups of springs 26, two in one group, and the two springs 26 are installed on both sides of one end of the centering rod 25. When the centering rod 25 is pushed by the push block 24, it can slide smoothly in the guide groove 27. At the same time, the spring 26 will provide a certain resistance, thereby ensuring the stability and accuracy of the centering rod 25 during the movement. When the push block 24 stops pushing, the spring 26 will use its elastic potential energy to push the centering rod 25 to perform a reset movement, so that it returns to its initial position for the next centering operation. In addition, the spring 26 also plays a buffering role. During the pipeline docking process, due to the influence of various factors, slight shocks or vibrations may occur. At this time, the spring 26 can absorb these shocks and vibrations, thereby protecting the centering rod 25 and the pipeline from damage.

[0028] Embodiment 2:

[0029] Working principle:

[0030] The pipe centering device 2 realizes the axial alignment and clamping and fixing functions of the pipe through a four-way correction mechanism. The key is to control the bidirectional movement of the push block 24 through the bidirectional cylinder 23, thereby pushing the centering rod 25 to slide in the guide groove 27 to achieve multi-directional centering adjustment of the pipe. At the same time, the spring 26 plays a role of reset and buffering to ensure the stability and accuracy of the centering rod 25.

[0031] Workflow:

[0032] Initial state: The pipeline is placed on the conveying seat 3 and moved to the position of the pipeline centering device 2. At this time, the centering rod 25 is in the initial position and the spring 26 is in the natural state.

[0033] Start centering: the conveying motor 4 stops, and the pipeline stops moving. The two-way cylinder 23 starts working, and its two ends push the two push blocks 24 to move inward. Due to the "concave"-shaped structural design of the push block 24, its inclined surface part contacts the arc-shaped end of the centering rod 25, transmitting the force to the centering rod 25.

[0034] Centering rod movement: Under the push of the push block 24, the centering rod 25 begins to slide in the guide groove 27. Due to the limitation of the guide groove 27, the centering rod 25 can accurately realize the centering operation of the pipeline. At the same time, the spring 26 is compressed to provide a certain resistance to ensure the smooth movement of the centering rod 25.

[0035] Pipeline centering: As the centering rod 25 moves, the pipeline is pushed evenly from four directions to achieve axis alignment. When the pipeline reaches the preset centering position, the two-way cylinder 23 stops working and the push block 24 stops moving. At this time, the centering rod 25 keeps clamping the pipeline under the action of the spring 26.

[0036] Completion of docking: After the pipeline is centered and fixed, the conveying motor 4 is started again to dock another pipeline with the centered pipeline. The above-mentioned centering operation is repeated for the other uncentered pipeline.

[0037] Reset preparation: After installation is completed, the bidirectional cylinder 23 works in the reverse direction to push the push block 24 to move outward. The centering rod 25 is reset to the initial position under the elastic potential energy of the spring 26 to prepare for the next centering operation.

[0038] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
