Description
Technical Field
[0001] This utility model relates to the field of pipeline docking technology, and in particular to a rapid docking device for surface pipelines. Background Technology
[0002] In the process of modern industrial development and urban infrastructure construction, surface pipelines are widely used in many fields such as oil transportation, natural gas transportation, and water supply and drainage projects. As various engineering projects continue to advance, the tasks of laying and maintaining surface pipelines are becoming increasingly arduous. Precise pipeline connection, as a crucial step, directly affects the sealing, stability, and service life of the entire pipeline. Therefore, efficient and reliable pipeline connection devices have become a focus of close attention throughout the industry.
[0003] Pipeline docking devices typically include a pipeline positioning mechanism, a clamping mechanism, an adjustment mechanism, and a welding connection mechanism. When the docking device is in operation, the pipeline positioning mechanism performs initial placement and positioning of the pipeline. Subsequently, the clamping mechanism firmly clamps the pipeline with its jaws. Next, the adjustment mechanism uses hydraulic or electric push rod components to make fine adjustments to the axial, radial position, and angle of the pipeline to ensure precise alignment of the pipe ends. Finally, the welding connection mechanism selects hot-melt welding or flange connection processes according to the pipeline material and actual engineering requirements to achieve a reliable connection between the pipelines.
[0004] In existing technologies, some pipe docking devices typically use clamps to fix the pipes in practical applications to complete the docking operation. However, many clamps have relatively simple designs and fixed specifications, which can only be adapted to pipes of specific diameters, reducing the practicality of the device. Therefore, a rapid docking device for surface pipes is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a quick docking device for surface pipelines, comprising a base 1 and two U-shaped frames 2. The base 1 is the basic support structure of the entire docking device, the U-shaped frames 2 are used to install clamping and fixing mechanisms, the two U-shaped frames 2 are provided with clamping and fixing mechanisms inside, and the base 1 is provided with a centering mechanism inside.
[0034] The clamping and fixing mechanism includes a fixing block 3, which provides a sliding track for the slider 4. The fixing block 3 is externally fixedly connected to the inside of the U-shaped frame 2. The slider 4 is slidably connected inside the U-shaped frame 2. The slider 4 slides on the surface of the fixing block 3. The fixing block 3 can drive the sliding plate 6 to move via the slide rod 5. The slider 4 is externally slidably connected to the outer surface of the fixing block 3. Two slide rods 5 are slidably connected inside the slider 4. When the slider 4 moves downward, it can drive the slide rods 5 to move through the inclined groove. Sliding plates 6 are fixedly connected to the outside of the two slide rods 5 respectively. Under the drive of the slide rods 5, the sliding plates 6 can move on the fixing block 3. The internal movement is simultaneously converted into the rotation of the arc-shaped clamping plate 8 via the connecting rod 7, thereby achieving the clamping action of the pipe. The two sliding plates 6 are rotatably connected to the outside of the connecting rod 7. When the sliding plate 6 moves, the distance between the two arc-shaped clamping plates 8 is changed through the transmission of the connecting rod 7, so as to clamp and fix the pipe. The outside of the two connecting rods 7 is rotatably connected to the inside of the U-shaped frame 2. The outside of the two connecting rods 7 is rotatably connected to the arc-shaped clamping plate 8. Through the transmission of the connecting rod 7, the two arc-shaped clamping plates 8 can move closer to each other to achieve the clamping of the pipe. The top of the two arc-shaped clamping plates 8 is provided with a locking component.
[0035] The locking assembly includes an elastic cord 9, the tension generated by the elastic cord 9 can lock the pipe and prevent the arc-shaped clamp 8 from being accidentally released. The elastic cord 9 is externally fixedly connected to the top of one of the arc-shaped clamps 8, and the top of the other arc-shaped clamp 8 is fixedly connected to a limiting post 10. The limiting post 10 provides a limiting function for the elastic cord 9, and the outer inner side of the elastic cord 9 is slidably connected to the outside of the limiting post 10.
[0036] Reference Figure 4The centering mechanism includes two connecting rods 11, which transmit the driving force of the centering mechanism to the U-shaped frame 2, thereby enabling the movement of the U-shaped frame 2. The tops of the two connecting rods 11 are fixedly connected to the bottoms of the two U-shaped frames 2 respectively. A driving component is fixedly connected inside the base 1. Two long rods 12 are rotatably connected to the outside of the driving component. Under the drive of the driving component, the long rods 12 can realize the centering action between the two U-shaped frames 2. The insides of the two long rods 12 are rotatably connected to the outside of the connecting rods 11 respectively.
[0037] The drive assembly includes a fixed base 14, which provides a mounting base for the electric push rod 15 and ensures the stability of the electric push rod 15 during operation. The fixed base 14 is externally fixedly connected to the inside of the base 1, and the electric push rod 15 is fixedly connected inside the fixed base 14. The electric push rod 15 drives the U-shaped block 13 to move, which in turn drives the long rod 12 and the connecting rod 11 to realize the relative movement of the two U-shaped frames 2 and complete the alignment operation of the pipeline. The drive end of the electric push rod 15 is fixedly connected to the U-shaped block 13, which is used to drive the long rod 12 to move. The exterior of both long rods 12 is rotatably connected to the interior of the U-shaped block 13.
[0038] Reference Figure 1 A fixing plate 17 is fixedly connected to the top of the base 1. The fixing plate 17 provides mounting support for the guide rod 18, ensuring the positional accuracy and stability of the guide rod 18, thereby ensuring that the U-shaped frame 2 moves in the correct direction. The guide rod 18 is fixedly connected to the outside of the fixing plate 17. The guide rod 18 provides a sliding track for the connecting block 16, allowing the U-shaped frame 2 to slide smoothly along the guide rod 18, playing a precise guiding role. Both U-shaped frames 2 are fixedly connected to the outside of the connecting block 16. The connecting block 16 has sliding holes machined inside to cooperate with the guide rod 18, allowing the U-shaped frame 2 to slide smoothly on the guide rod 18, ensuring that the U-shaped frame 2 moves smoothly during the movement. To ensure straightness and stability, the interiors of the two connecting blocks 16 are slidably connected to the exterior of the guide rod 18. The tops of the two bases 1 are provided with guide grooves 20, which ensure that the pulleys 19 can slide, reducing friction for the movement of the U-shaped frame 2. The bottom of the base 1 is fixedly connected with multiple support columns 21, which support the entire device and keep it at a certain distance from the ground, reducing the impact of uneven ground on the stability of the device. The bottoms of the U-shaped frame 2 are fixedly connected with pulleys 19, which roll in the guide grooves 20, making the movement of the U-shaped frame 2 smoother. The bottoms of the pulleys 19 are slidably connected inside the guide grooves 20.
[0039] Working principle: The pipes to be connected are placed in the clamping and fixing mechanisms in the two U-shaped frames 2 respectively. The pipes press the slider 4, and the slider 4 slides along the surface of the fixing block 3 in the U-shaped frame 2. The movement of the slider 4 drives the sliding rod 5 through the inclined groove. The sliding rod 5 drives the sliding plate 6 to move inside the fixing block 3. The sliding plate 6 causes the arc-shaped clamp 8 to rotate through the connecting rod 7. The two arc-shaped clamps 8 move closer to each other and clamp the pipes. Finally, the elastic rope 9 is put on the limiting post 10. The tension generated by the elastic rope 9 locks the arc-shaped clamp 8 and prevents the arc-shaped clamp 8 from being accidentally released.
[0040] After the pipe is fixed, the electric push rod 15 is activated. The electric push rod 15 drives the U-shaped block 13 to move. The U-shaped block 13 drives the long rod 12 to move. The long rod 12 pushes the connecting rod 11, so that the two U-shaped frames 2 move smoothly relative to each other through the connecting block 16 and pulley 19 under the guidance of the guide rod 18 and the guide groove 20, and perform the centering operation to achieve accurate pipe docking.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
