Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline construction technology, specifically to a pipeline connection device for water conservancy engineering construction. Background Technology
[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals.
[0003] Currently, existing water conservancy projects require pipe welding during construction, and pipe docking is necessary before welding. During docking, one of the pipes needs to be manually moved to achieve auxiliary alignment between the two adjacent pipes. The manual docking involves a large range of pipe movement, making it impossible to precisely adjust the distance between the two pipes. Therefore, it is time-consuming, labor-intensive, inefficient, and prone to large docking errors. To avoid these problems, a pipe docking device that can finely adjust the distance between two adjacent pipes has been developed.
[0004] While existing pipe-connecting devices can fine-tune the spacing between two pipes, improving connection efficiency to some extent, the long length and circular shape of the pipes, coupled with the complex and varied construction sites, mean that the other end of the pipe can easily roll on uneven ground. Although one end of the pipe can connect two adjacent pipes, the surfaces of the two adjacent pipes after connection cannot completely overlap. This can easily result in a partial contact of the circular cross-sections of the two adjacent pipes while the other part separates, forming a large gap. The connection effect is poor, affecting subsequent welding work. Utility Model Content
[0005] The purpose of this utility model is to provide a pipeline docking device for water conservancy engineering construction. It uses two symmetrical clamping components to clamp the ends of two adjacent pipelines, and uses a bidirectional drive component to finely adjust the distance between the two adjacent pipelines. The contact surfaces of the ends of the two adjacent pipelines are adjusted by the fastening components that can move back and forth and up and down on the outside of the clamping components, so that the two end faces completely overlap after docking, thereby improving the docking effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipeline connection device for water conservancy engineering construction, comprising a base, two connecting seats symmetrically and slidably arranged on the top of the base, each connecting seat having a clamping component that cooperates with the pipeline on its top, a bidirectional driving component for driving the two connecting seats to move left and right on the base and between the two connecting seats, a lifting plate for each of the two connecting seats, a first driving component for driving the lifting plate to move up and down on the top of the base, a sliding plate for sliding back and forth on the top of the lifting plate, a second driving component for driving the sliding plate to slide back and forth on the lifting plate, and a fastening component that cooperates with the pipeline fixedly arranged on the top of the sliding plate.

[0033] Preferably, two symmetrical clamping components 5 are used to clamp the ends of two adjacent pipes, and a bidirectional drive component 6 is used to cooperate with the two clamping components 5 to finely adjust the distance between the two adjacent pipes. A height-adjustable lifting plate 7 is provided on the base 1 and outside the clamping components 5. A front-to-back adjustable sliding plate 9 is provided on the top of the lifting plate 7, and a fastening component 11 for cooperating with the pipe is fixedly provided on the top of the sliding plate 9. By adjusting the height of the lifting plate 7 and the front-to-back position of the sliding plate 9, the fastening component 11 is moved back-to-back and up-to-down, thereby adjusting the angle of the pipe. By adjusting the angle of the pipe, the end faces of the two pipes after docking are completely overlapped, avoiding gaps, improving the docking effect, and facilitating subsequent welding work.
[0034] Working principle:
[0035] First, the distance between the two clamping components 5 is adjusted to their maximum distance using the bidirectional drive component 6. Next, the height and position of the fastening component 11 are roughly adjusted using the cooperation of the first drive component 8 and the second drive component 10. Then, the two ends to be joined are sequentially inserted through the fastening component 11 and the clamping component 5 from the outside in, and the clamping component 5 clamps the end of the pipe. The fastening component 11 then clamps the middle of the pipe. When the ends of two adjacent pipes are joined, the relative movement of the two clamping components 5 is controlled by the bidirectional drive component 6. When the two clamping components 5 move relative to each other, the ends of the two pipes slowly approach and contact each other. When the ends of the two pipes contact each other, the cross-sections may not completely overlap. Then, the first driving component 8 drives the lifting plate 7 to adjust its height and the second driving component 10 drives the sliding plate 9 to adjust its position. When the lifting plate 7 and the sliding plate 9 are adjusted, the fastening component 11 changes position. When the fastening component 11 changes position, the angle of the pipe is adjusted. The angle adjustment of the pipe makes the end faces of the two pipes completely overlap after docking, which facilitates the subsequent welding work.
