DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0033] like Figure 1 As shown, a pipe docking device provided in this embodiment is used for docking a first pipe 6 and a second pipe 7. The first pipe 6 is connected to a graphitization furnace 5. The pipe docking device includes a first docking end 1, a second docking end 2, a driving mechanism 3 and a bracket 4. The bracket 4 includes a frame 41 and a platform 42 disposed on the upper end of the frame 41. The frame 41 is disposed on the ground beside the graphitization furnace 5. The second pipe 7 is passed through the interior of the frame 41.

[0034] like Figure 2 As shown, the first docking end 1 includes a first docking plate 11 , a sealing box 12 , a docking hole 13 , a first valve core 14 and a guide hole 15 .

[0035] The sealing box 12 is connected to the middle of one side of the first docking plate 11, and a docking hole 13 penetrating the first docking plate 11 is provided in the sealing box 12. One end of the sealing box 12 away from the first docking plate 11 is connected to the first tube 6. A first valve core 14 is provided on the inner bottom surface of the sealing box 12 for sealing the first tube 6 after the docking device is separated. Two diagonally arranged guide holes 15 are provided on the first docking plate 11.

[0036] like Figure 3 , Figure 4 As shown, the second docking end 2 includes a second docking plate 21 , a third docking plate 22 , a joint 23 , a guide rod 24 , a second valve core 25 , a sealing ring 26 , a spring 27 , a connecting rod 28 and an ear seat 29 .

[0037] The first docking plate 11, the second docking plate 21 and the third docking plate 22 are circular plates with equal diameters. The third docking plate 22 is located below the second docking plate 21. The connecting rod 28 passes through the third docking plate 22 from below the third docking plate 22 and is connected to the lower surface of the second docking plate 21, so that the third docking plate 22 and the connecting rod 28 are loosely matched. Three or more connecting rods 28 are diagonally arranged on the second docking plate 21. Each of the connecting rods 28 is provided with a spring 27, and the spring 27 abuts between the second docking plate 21 and the third docking plate 22. Under the action of the spring 27, the third docking plate 22 can move up and down along the connecting rod 28. The lower surface of the third docking plate 22 is connected to an ear seat 29, and two of the ear seats 29 are diagonally arranged.

[0038] The upper surface of the second docking plate 21 is provided with two guide rods 24 and a joint 23. The joint 23 is located in the middle, and the two guide rods 24 are arranged diagonally. The upper end of the guide rod 24 is provided with a cone head, and the upper end of the joint 23 is provided with a guide cone angle 231. The upper surface of the joint 23 is provided with a second valve core 25. The joint 23 is also provided with a sealing ring 26. The height of the guide rod 24 is greater than the height of the joint 23.

[0039] like Figure 1 , Figure 5 As shown, the driving mechanism 3 is an electric push rod, which is provided with an A end and a B end, the A end is placed on the platform 42, and the B end is connected to the ear seat 29. Each ear seat 29 is connected to a driving mechanism 3. The lower end of the joint 23 is connected to the second tube 7 through the third tube 8, and the third tube 8 is a hose.

[0040] During docking, the driving mechanism 3 is started to drive the second docking end 2 to move upward, and the third tube 8 of the hose can adapt to the upward movement of the second docking end 2. First, the cone head of the guide rod 24 is aligned with the guide hole 15, and as the guide rod 24 enters the guide hole 15, the connector 23 enters the sealing box 12. For example, when there is an angle deviation between the first docking end 1 and the second docking end 2, the second docking end 2 can adapt to the angle deviation through the spring 27 during the upward movement, so that the axis of the second docking end 2 coincides with the axis of the first docking end 1. Until the connector 23 is fully inserted into the sealing box 12, the sealing ring 26 abuts against the inner wall of the sealing box 12 to seal. At this time, the first valve core 14 and the second valve core 25 are in contact and connected. If the first valve core 14 and the second valve core 25 are separated, the two will automatically close and cut off the flow, without the need to manually close the valve, which can extend the service life of the valve on the pipeline. The docking is completed.

[0041] The first butt end 1 and the second butt end 2 are both self-sealing structures.

[0042] The utility model does not require manual participation in docking, realizes automatic docking through various guide mechanisms, structures and driving mechanisms, realizes automatic connection and disconnection of fluid through the setting of the valve core, and effectively improves the efficiency of pipeline docking.

[0043] The pipe docking device provided by the utility model is not limited to the graphitization furnace, and can also be applied to other similar pipe docking. In addition, the fluid is not limited to cooling water, and other toxic and harmful gases and liquids can be used.

[0044] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
