[0026] Please see Figures 1 to 11 This embodiment provides an automatic pipeline docking device, including a bracket 1. The bracket 1 can be a frame structure or welded from steel pipes or I-beams to provide overall support for the equipment installed on the bracket 1. A connecting plate 6 is movably disposed at the top of the bracket 1, and a drive mechanism 2 is disposed at one end of the bracket 1. The drive mechanism 2 can drive the connecting plate 6 to reciprocate along the length of the bracket 1 to facilitate docking of the first pair of connecting pipes 7 and the second pair of connecting pipes 11 fixedly installed on the second pair of connecting pipe fixing frame 13.

[0027] Specifically, a cylinder 14 is fixedly mounted on the bottom surface of the connecting plate 6. The cylinder 14 is used to drive the first pair of connecting pipes 7 to rise and fall. In this embodiment, the cylinder 14 is fixed to the connecting plate 6 by bolts. The piston rod of the cylinder 14 extends through the connecting plate 6 to the top surface of the connecting plate 6. The end of the piston rod is fixedly connected to one end of the first pair of connecting pipes 7. The end of the first pair of connecting pipes 7 that is fixedly connected to the piston rod is fixedly connected to a first pipe connector 8. The end of the first pair of connecting pipes 7 away from the first pipe connector 8 extends through the connecting plate 6 to the bottom surface of the connecting plate 6, and the end of the first pair of connecting pipes 7 away from the first pipe connector 8 can be connected to other pipes.

[0028] Specifically, the second pipe connector fixing frame 13 can be made of metal and is fixed to the support frame of the silo, or it can be made into an independent support according to the actual situation. Several second pipe connectors 11 are fixedly mounted on the second pipe connector fixing frame 13. The second pipe connectors 11 are fixedly mounted on the second pipe connector fixing frame 13 by fixing clamps 17, which are U-shaped. A second pipe joint 12 is fixedly mounted at one end of each second pipe connector 11. During manufacturing, the second pipe connectors 11 and 12 are respectively machined and then welded together into a single unit using welding equipment. The second pipe joint 12 mates with the first pipe joint 8. In this embodiment, the second pipe joint 12 extends into the first pipe joint 8, that is, the shape of the outer surface of the second pipe joint 12 matches the shape of the inner surface of the first pipe joint 8.

[0029] Specifically, the inner surface of the first pipe connector 8 is shaped like a frustum, and the outer surface of the second pipe connector 12 is shaped like a frustum. In this embodiment, the inner surface of the first pipe connector 8 is shaped like a frustum of a cone, and the outer surface of the second pipe connector 12 is shaped like a frustum of a cone. The inner surface of the first pipe connector 8 and the outer surface of the second pipe connector 12 mate. When the first pipe connector 8 and the second pipe connector 12 are joined, they form a tapered joint, which can achieve a seamless and tight fit, without jamming or residue.

[0030] Specifically, in this invention, a stepper motor 21 controls the precise movement of the connecting plate 6, and a cylinder 14 controls the lifting and lowering of the first connecting pipe 7. Operators can precisely move the connecting plate 6 and the first connecting pipe 7 using only button operation or remote computer control, thereby achieving the docking of the first connecting pipe 7 and the second connecting pipe 11. This device enables rapid and precise pipe connection.

[0031] Specifically, a linear guide rail 3 is fixedly mounted on the top of the bracket 1, and a slider 4 slides on the linear guide rail 3. A connecting plate 6 is fixedly connected to the slider 4. The driving mechanism 2 causes the connecting plate 6 to reciprocate along the length of the linear guide rail 3 via the slider 4, so as to facilitate the docking of the first pair of connecting pipes 7 and the second pair of connecting pipes 11.

[0032] Specifically, the drive mechanism 2 includes a stepper motor 21, which is fixedly mounted on one end of the bracket 1 via a motor support 5. A lead screw 22 is connected to the output end of the stepper motor 21. The end of the lead screw 22 away from the stepper motor 21 is rotatably mounted on the bracket 1 via a bearing seat 24. A lead screw nut 23 matching the lead screw 22 is fixed to the bottom end of the connecting plate 6, and the lead screw nut 23 is threadedly connected to the lead screw 22. During operation, the stepper motor 21 drives the lead screw 22 to rotate, the rotation of the lead screw 22 causes the lead screw nut 23 to move horizontally, and the lead screw nut 22 drives the connecting plate 6 to move. The connecting plate 6 reciprocates on the linear guide 3 via a slider 4.

[0033] Specifically, the first connecting pipe 7 is fixedly connected to the first pipe connector 8 at one end with a mounting flange 9. During installation, the first pipe connector 8 is bolted to the mounting flange 9, which also has a mounting hole 10. The piston rod of the cylinder 14 has a shoulder boss 15 at its end, which supports the lower surface of the mounting flange 9 during installation of the first connecting pipe 7. The portion of the piston rod above the shoulder boss 15 is threaded, and the thread engages with the fastening nut 16. During installation, the piston rod of the cylinder 14 is passed through the mounting hole 10, and the lower surface of the mounting flange 9 rests against the shoulder boss 15, providing support. Then, the fastening nut 16 is engaged with the threaded portion of the piston rod, and the fastening bolt 16 is tightened to fix the mounting flange 9 to the end of the piston rod, thus completing the connection between the first connecting pipe 7 and the cylinder 14. During operation, the connecting plate 6 drives the first pair of connecting pipes 7 to move below the second pair of connecting pipes 11. The piston rod of the cylinder 14 drives the first pair of connecting pipes 7 to move upward. The second pipe joint 12 extends into the first pipe joint 8 and cooperates with the first pipe joint 8, thereby completing the docking of the first pair of connecting pipes 7 and the second pair of connecting pipes 11.

[0034] Specifically, the working principle of this utility model is as follows: the stepper motor 21 is started, the stepper motor 21 drives the lead screw 22 to rotate, the rotation of the lead screw 22 drives the lead screw nut 23 to move horizontally, the lead screw nut 22 drives the connecting plate 6 to move, the connecting plate 6 moves on the rail 3 through the slider 4, when the connecting plate 6 moves to below the second pair of pipes 11 to be connected to the first pair of pipes 7, the piston rod of the cylinder 14 drives the first pair of pipes 7 to move upward, the second pipe joint 12 extends into the first pipe joint 8, the second pipe joint 12 and the first pipe joint 8 complete the cooperation, thereby completing the connection between the first pair of pipes 7 and the second pair of pipes 11. When the first pair of connectors 7 needs to be connected to the next second pair of connectors 11, the piston rod of the cylinder 14 drives the first pair of connectors 7 to move downward, the first pipe joint 8 and the second pipe joint 12 separate, and then the moving plate 6 moves to below the next second pair of connectors 11, the piston rod of the cylinder 14 drives the first pair of connectors 7 to move upward, and the second pipe joint 12 extends into the first pipe joint 8, and the two complete the engagement, realizing the connection between the first pair of connectors 7 and the next second pair of connectors 11.
