Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, and more specifically, to a pipeline docking device. Background Technique

[0002] A pipeline is a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles.

[0003] During the production or installation of pipelines, the docking operation between two pipelines is inevitable. For convenience during docking, auxiliary devices are often installed at the docking location to support the pipeline ends, thereby achieving the effect of assisting docking. The devices used for pipeline docking generally require manual movement for docking, which is time-consuming and laborious. Moreover, because the diameters of different pipelines are different, when docking pipelines with different diameters, different-sized fixing components need to be used separately for auxiliary stability before docking can be carried out.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a pipeline docking device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A pipeline docking device includes a tabletop. Four corners at the bottom of the tabletop are fixedly installed with support leg rods, which are perpendicular to the tabletop. The center of the top of the tabletop is fixedly installed with an alignment mechanism. Clamping mechanisms are installed at opposite ends at the top of the alignment mechanism. The alignment mechanism includes a fixed frame fixedly installed on the top of the tabletop. Cross beam rods are symmetrically installed along the center at the top of the fixed frame. The cross beam rods are arranged along the width direction of the fixed frame. Slide rails are fixedly installed at both ends at the top of the cross beam rods. The slide rails are arranged along the length direction of the cross beam rods. A cross moving plate is also provided above the cross beam rods. The clamping mechanisms are fixedly installed on the top of the cross moving plate. The cross moving plate is arranged along the length direction of the fixed frame. Sliding seats are fixedly installed at both ends near the length direction at the bottom of the cross moving plate. The sliding seats are slidably installed on the slide rails. A fixed plate is fixedly installed at the top between the two cross beam rods. A bearing seat is installed at the center of the top of the fixed plate. A vertical shaft is rotatably installed in the bearing seat. A rotating plate is fixedly installed on the vertical shaft. Both ends of the rotating plate are respectively connected to the cross moving plates on both sides through connecting rods.

[0008] Further, a connecting beam is fixedly installed at the top of the fixed frame. There are two connecting beams, and the two connecting beams are arranged outside the two cross beam rods. An adjusting cylinder arranged along the length direction thereof is fixedly installed at the top of the connecting beam. Connecting blocks are fixedly installed at both ends of the cross moving plate near one side of the output shaft of the adjusting cylinder, and the end of the output shaft of the adjusting cylinder is fixedly connected with the connecting block.

[0009] Further, hinge pins are fixedly installed at both ends of the top of the rotating plate and at the center of one side of the top of the cross moving plate facing the rotating plate. Both ends of the connecting rod are rotatably connected with the hinge pins.

[0010] Further, the clamping mechanism includes a support plate arranged directly above the cross moving plate. The bottom of the support plate is fixedly installed on the cross moving plate through support columns. The support plate is arranged along the length direction of the cross moving plate. A support frame is fixedly installed at the top of the support plate. A horizontal column arranged along the width direction of the cross moving plate is fixedly installed at the center of the top of the support frame. Support blocks are fixedly installed near both ends and in the middle of the top of the horizontal column. An assembly plate is integrally arranged at the top end of the support block, and a positioning block is installed at the top of the assembly plate. The top of the positioning block is arc-shaped.

[0011] Further, vertical plates are fixedly installed at both ends of the top of the support frame along the length direction of the horizontal column. A side plate is further arranged on one side of the vertical plate away from the support frame. A clamping assembly is also installed between the vertical plate and the side plate on the same side of the support frame.

[0012] Further, the clamping assembly includes two relatively arranged clamping jaws. Corrugated blocks are fixedly installed on the opposite sides of the tops of the clamping jaws. A mounting shaft is installed in the middle of the clamping jaws. Both ends of the mounting shaft are respectively rotatably connected with the top ends of the side of the vertical plate and the side plate. A connecting shaft is installed at the bottom of the clamping jaw. A clamping cylinder is further arranged between the connecting shafts at the bottoms of the two relatively arranged clamping jaws.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the alignment mechanism, the utility model can drive two clamping mechanisms to move towards each other. The positioning blocks and clamping jaws installed on the clamping mechanisms can clamp pipes with different pipe diameters. The clamped pipes then move towards each other through the drive of the cross moving plate, thereby realizing stable alignment. And because the movement of the cross moving plate only needs to be controlled separately by the adjusting cylinder, only one cross moving plate needs to be moved and adjusted, and the other cross moving plate can realize automatic movement, ensuring the stability and reliability during docking.

Detailed implementation manners

[0025] Next, in combination with the drawings and specific implementation manners, a further description will be made of the present invention:

[0026] Please refer to Figure 1-7 A pipeline docking device according to an embodiment of the present utility model includes a tabletop 1. Four corners of the bottom of the tabletop 1 are fixedly installed with leg rods 2, and the leg rods 2 are perpendicular to the tabletop 1. A centering mechanism 3 is fixedly installed at the center of the top of the tabletop 1. Clamping mechanisms 4 are installed at opposite ends of the top of the centering mechanism 3. The ends of two pipelines are positioned and clamped by the clamping mechanisms 4, and then the positions of the two clamping mechanisms 4 are synchronously adjusted by the centering mechanism 3, thereby realizing the docking of the ends of the two pipelines.

[0027] In order to enable the centering mechanism 3 to synchronously adjust the clamping mechanisms 4 at both ends, in this embodiment, the centering mechanism 3 includes a fixed frame 5. The fixed frame 5 is fixedly installed on the top of the tabletop 1. Cross beam rods 6 are symmetrically installed along the center of the top of the fixed frame 5, and the cross beam rods 6 are arranged along the width direction of the fixed frame 5. Slide rails 7 are fixedly installed at both ends of the top of the cross beam rods 6, and the slide rails 7 are arranged along the length direction of the cross beam rods 6. A cross moving plate 8 is also provided above the cross beam rods 6. The clamping mechanism 4 is fixedly installed on the top of the cross moving plate 8. The cross moving plate 8 is arranged along the length direction of the fixed frame 5, and sliding seats 9 are fixedly installed at both ends of the bottom of the cross moving plate 8 close to its length direction. The sliding seats 9 are slidably installed on the slide rails 7. A fixing plate 10 is fixedly installed at the top between the two cross beam rods 6. A bearing seat 11 is installed at the center of the top of the fixing plate 10. A vertical shaft 12 is rotatably installed in the bearing seat 11. A rotating plate 13 is fixedly installed on the vertical shaft 12. Both ends of the rotating plate 13 are respectively connected to the cross moving plates 8 on both sides through connecting rods 14.

[0028] When one side of the cross moving plate 8 is forced to slide on the slide rail 7 through the sliding seat 9, the moving cross moving plate 8 will rotate the rotating plate 13 through the connecting rod 14 connected thereto. The rotating plate 13 will rotate in the bearing seat 11 through the vertical shaft 12. The rotating rotating plate 13 will also drive the cross moving plate 8 on the other side to move through the connecting rod 14 at the other end, thereby realizing the opposite or away movement of the two cross moving plates 8. When the cross moving plates 8 move towards each other, the two pipelines can be driven to dock through the clamping mechanisms 4 installed on their tops.

[0029] In order to enable the movement of the cross moving plate 8 to be automatically adjusted, in this embodiment, a connecting beam 16 is also fixedly installed on the top of the fixed frame 5. There are two connecting beams 16, and the two connecting beams 16 are arranged outside the two cross beam rods 6. A regulating cylinder 17 arranged along its length direction is fixedly installed on the top of the connecting beam 16. Connecting blocks 18 are fixedly installed at both ends of the cross moving plate 8 close to the output shaft side of the regulating cylinder 17. The end of the output shaft of the regulating cylinder 17 is fixedly connected to the connecting block 18. Hinge pins 15 are fixedly installed at both ends of the top of the rotating plate 13 and at the center of the top of the cross moving plate 8 facing the rotating plate 13. Both ends of the connecting rod 14 are rotatably connected to the hinge pins 15.

[0030] In order to enable the clamping mechanism 4 to stably clamp the pipeline, in this embodiment, the clamping mechanism 4 includes a support plate 19 disposed directly above the transverse movement plate 8. The bottom of the support plate 19 is fixedly installed on the transverse movement plate 8 through a support column 20. The support plate 19 is arranged along the length direction of the transverse movement plate 8. A support frame 21 is fixedly installed at the top of the support plate 19. A horizontal column 22 arranged along the width direction of the transverse movement plate 8 is fixedly installed at the center of the top of the support frame 21. Support blocks 23 are fixedly installed near both ends and in the middle of the top of the horizontal column 22. An assembly plate 24 is integrally provided at the top end of the support block 23. A positioning block 25 is installed on the top of the assembly plate 24. The top of the positioning block 25 is arc-shaped. The outer wall of the end of the pipeline is supported by the support block 23. When the transverse movement plate 8 moves, the pipeline can be driven to move synchronously, and then the ends of the pipeline on the two positioning blocks 25 are butted. In order to enable the pipeline on the positioning block 25 to remain stable during the movement and docking, vertical plates 26 are fixedly installed at both ends of the top of the support frame 21 arranged along the length direction of the horizontal column 22. A side plate 27 is also provided on the side of the vertical plate 26 away from the support frame 21. A clamping assembly 28 is also installed between the vertical plate 26 and the side plate 27 on the same side of the support frame 21. The clamping assembly 28 is used to clamp the outer wall of the pipeline on the top of the support block 23. With the arc-shaped groove on the top of the support block 23, stable positioning of the pipeline can be achieved.

[0031] In order to enable the clamping assembly 28 to achieve automatic adjustment, and thus facilitate the clamping and loosening of the pipeline, in this embodiment, the clamping assembly 28 includes two relatively arranged clamping jaws 29. Corrugated blocks 30 are fixedly installed on the opposite sides of the top of the clamping jaws 29. An installation shaft 31 is installed in the middle of the clamping jaws 29. Both ends of the installation shaft 31 are rotatably connected to the top ends of the side of the vertical plate 26 and the side plate 27 respectively. A connecting shaft 32 is installed at the bottom of the clamping jaws 29. A clamping cylinder 33 is also provided between the connecting shafts 32 at the bottoms of the two relatively arranged clamping jaws 29. Both ends of the clamping cylinder 33 are connected to the connecting shafts 32 on both sides. By controlling the start of the clamping cylinder 33, the clamping cylinder 33 can drive the clamping jaws 29 to rotate around the installation shaft 31 through the connecting shaft 32. When the corrugated block 30 at the end of the clamping jaws 29 contacts the outer wall of the pipeline, clamping and positioning of the pipeline can be achieved.

[0032] Through the above solution of the present utility model, the present utility model can drive the two clamping mechanisms 4 to move towards each other through the alignment mechanism 3. The positioning blocks 25 and the clamping jaws 29 installed on the clamping mechanism 4 can clamp pipelines with different pipe diameters. The clamped pipelines then move towards each other through the drive of the transverse movement plate 8, and thus stable butt joint is achieved. And because the movement of the transverse movement plate 8 only needs to be controlled separately by the adjustment cylinder 17, so as long as one transverse movement plate 8 is moved and adjusted, the other transverse movement plate 8 can achieve automatic movement, ensuring the stability and reliability during docking.
