DETAILED DESCRIPTION

[0030] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words such as 'up', 'down', 'left', 'right' appear in the following text, they only mean consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure.

[0031] As Figure 1As shown, the pipe docking device provided in this embodiment includes a mobile device 21, a docking component 22, and a fixing component 23.

[0032] The mobile device 21 can be equipped with an X and Z axis motion module, which outputs only the horizontal and vertical degrees of freedom.

[0033] like Figure 3 As shown, the docking component 22 includes a first pipe 1, a side plate 2, a stiffening plate 3, an upper plate 4, and a first valve 6. The side plate 2 is vertically connected to the upper plate 4, and the upper plate 4 is horizontally arranged. The side plate 2 and the upper plate 4 are connected by the stiffening plate 3. Two first pipes 1 are installed on the upper plate 4, and the openings of the first pipes 1 penetrate the upper plate 4 and are flush with the outer surface of the upper plate 4. The first valve 6 is provided on the first pipe 1. Figure 1 As shown, one end of the upper plate 4 or the side plate 2 is mounted on the mobile device 21.

[0034] like Figure 3 , Figure 4 As shown, the fixing component 23 includes a buffer 5, a lower plate 10, a sealing ring 11, a flow meter 12, a second valve 13, a second pipe 14, and a support 15.

[0035] like Figure 5 As shown, the buffer 5 includes a spring 17, a guide post 18, a guide sleeve 20, and an adjusting rod 19. The lower end of the guide sleeve 20 is mounted on the top plate 7 of the support 15 (e.g., Figure 3 As shown, the lower end of the guide post 18 is adapted to the guide sleeve 20, and the upper end of the guide post 18 extends to the outside of the guide sleeve 20. A spring 17 is fitted onto the protruding part of the guide post 18, and the spring 17 abuts against the lower plate 10 and the guide sleeve 20. The lower plate 10 has a mounting hole 101. An adjusting rod 19 (using a screw) is installed at the upper end of the guide post 18 in the mounting hole 101. The mounting hole 101 is a tapered hole, smaller at the top and larger at the bottom, near the buffer 5. The upper end of the mounting hole 101 is a cylindrical hole, and the bolt head of the adjusting rod 19 is limited by the cylindrical hole to prevent it from coming out. The screw of the adjusting rod 19 can deflect within the tapered hole. In the initial state, the spring 17 pushes out of the lower plate 10, causing the bolt head of the adjusting rod 19 to engage with the side wall of the cylindrical hole. The guide post 18 is a T-shaped rod, with its larger head positioned within the guide sleeve 20. The T-shaped structure reduces the contact area between the guide post 18 and the guide sleeve 20, making assembly easier.

[0036] like Figure 3 , Figure 4As shown, the lower plate 10 is a rectangular plate, and the buffer 5 is installed around the lower plate 10. The second pipe 14 is installed on the lower plate 10, and the pipe opening of the second pipe 14 penetrates and embeds the sealing ring 11 at the pipe opening. The second pipe 14 corresponds in number to the first pipe 1. The second pipe 14 is provided with a second valve 13 and a flow meter 12. And the end of the second pipe 14 is provided with a thread 16 for interfacing with other pipes.

[0037] The support 15 includes a top plate 7 and a stand 9 connected around the top plate 7, and the stand 9 is supported on the ground. The buffer 5 is connected to the top plate 7, the lower plate 10 is located above the top plate 7, and the second pipe 14 penetrates the top plate 7. The upper surface of the support 15 is provided with a surrounding plate 8 for surrounding the second pipe 14, and the surrounding plate 8 is arranged in a spaced manner with the lower plate 10 (as Figure 6

[0038] The utility model provides a method for pipeline interfacing device to carry out pipeline interfacing, comprising the following steps:

[0039] S1, set up mobile equipment 21 horizontal displacement stroke L1 and lower stroke L2;

[0040] S2, as shown in the drawing, install the interfacing component 22 on the mobile equipment 21; Figure 1

[0041] S3, as shown in the drawing, start the mobile equipment 21 and carry out horizontal displacement to stroke L1 and lower stroke L2 in turn; Figure 2

[0042] S3.1, in the process of stroke L2, a part of the upper plate 4 is first pressed on the lower plate 10, the first force receiving part of the lower plate 10 presses the buffer 5 to make the lower plate 10 incline, the bolt head of the adjusting rod 19 extends the upper part of the mounting hole 101, and the screw rod is inclined in the conical hole (as Figure 6

[0043] S3.2, when reaching stroke L2, the upper plate 4 and the lower plate 10 are completely attached, the sealing ring 11 is compressed, and the first pipe 1 and the second pipe 14 are interfaced;

[0044] S4, start the first valve 6 and the second valve 13, and the medium enters the second pipe 14 from the first pipe 1;

[0045] S5, the error between the flow meters 12 on the two second pipes 14 can be compared through the computer end, if the error exceeds the set value, it is determined that there is leakage, then the first valve 6 and the second valve 13 are closed, the leakage position is repaired, and until the use requirement is reached. ​​​​

[0046] This invention features a tapered hole on the lower plate 10, with a certain gap between the tapered hole and the adjusting rod 19. This gap causes the spring 17 on each buffer member 5 to have a different compression amount. Figure 6 As shown, when the mating component 22 is misaligned due to execution error, the upper plate 4 presses down on the lower plate 10, causing one side of the spring 17 to be compressed first, while the other side is compressed later. Due to the set gap, the compression of the springs 17 on both sides can be unequal, thus allowing the lower plate 10 to adapt to the misaligned installation situation.

[0047] like Figure 7 As shown, the diameter of the second pipe 14 is larger than that of the first pipe 1. When the displacement accuracy of the mobile device 21 is low and the pipe centers are not aligned, the two pipes can still be connected. This simplifies the structure of the docking device, reduces the accuracy requirements of the docking device, and enables the docking device to successfully dock even when the pipe center is offset or the installation is skewed, thereby improving the success rate, reducing the error rate, and lowering costs.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
