[0030] like Figures 1 to 3As shown, the present application provides a pipe docking device for docking a first pipe and a second pipe. An embodiment of the pipe docking device of the present application includes: a first docking portion 10 and a second docking portion 20; the first docking portion 10 has a first clamping cavity 11 for placing the first pipe; the second docking portion 20 includes a base 22, a driving portion and a clamping plate 23 slidably arranged on the base 22, and a second clamping cavity 21 for clamping the second pipe is provided between the base 22 and the clamping plate 23, the driving portion is drivingly connected to the clamping plate 23 and can drive the clamping plate 23 to move toward or away from the first docking portion 10, and when the clamping plate 23 moves, it drives the second pipe to move so that the second pipe can dock with the first pipe.

The second docking part 20 includes a base 22, a driving part and a clamping plate 23 slidably arranged on the base 22. A second clamping cavity 21 for clamping the second pipe is provided between the base 22 and the clamping plate 23. The second pipe is carried on the base 22 and clamped in the second clamping cavity 21. The driving part is drivably connected to the clamping plate 23 and can drive the clamping plate 23 to move toward or away from the first docking part 10. When the first pipe and the second pipe need to be docked, the clamping plate 23 is moved toward the first docking part 10, so that the clamping plate 23 drives the second pipe to move toward the first docking part 10, thereby realizing the docking of the second pipe and the first pipe, and preparing for subsequent work. Compared with the solution of manually docking pipes in the related field, the pipe docking device of this embodiment can accurately realize the docking of the first pipe and the second pipe. Therefore, the technical solution of this embodiment can effectively solve the problem of poor pipe docking accuracy in related technologies.

[0032] It should be noted that, in the present embodiment, when the first pipe and the second pipe are connected, the connected pipe can be pulled out from the first clamping cavity 11 or from the second clamping cavity 21; in addition, in the present embodiment, the structure and function of the first docking part 10 and the second docking part 20 are similar, and the first docking part 10 will not be described in detail, and the structure of the second docking part 20 will be described in detail later.

[0033] like Figures 1 to 3As shown, the second docking portion 20 further includes a transmission rod 24 and a connecting frame 25, the clamping plate 23 is connected to the connecting frame 25, the transmission rod 24 is connected between the driving portion and the connecting frame 25 and is driven and cooperated with both the driving portion and the connecting frame 25 to drive the connecting frame 25 to move, thereby driving the clamping plate 23 to move. Specifically, the connecting frame 25 includes a vertical frame and two horizontal frames, the two horizontal frames are connected to the upper and lower ends of the vertical frame, the middle part of the upper horizontal frame is connected to the clamping plate 23 through a vertical rod, and the end of the lower horizontal frame away from the vertical frame is drivingly connected to the transmission rod 24, and the driving portion drives the transmission rod 24 to rotate, thereby driving the connecting frame 25 to move.

[0034] like Figures 1 to 3 As shown, the second docking portion 20 further includes a slider 26 and a guide rail 27, and the slider 26 is connected to the connecting frame 25 and slidably disposed in the guide rail 27. Specifically, the slider 26 is connected to the lower end of the vertical frame and the end of the horizontal frame below close to the vertical frame, and the slider 26 and the guide rail 27 are guided and matched, thereby ensuring that the connecting frame 25 moves in a preset direction, thereby ensuring the moving direction of the clamping plate 23, and ensuring the accuracy of the pipeline docking.

[0035] like Figures 1 to 3 As shown, the driving part includes a first driving motor, a transmission rod 24 is connected to the output shaft of the first driving motor and rotates synchronously with the output shaft, and a connecting frame 25 and a transmission rod 24 are threadedly matched, so that when the transmission rod 24 rotates, the connecting frame 25 is driven to move. Specifically, the connecting frame 25 and the transmission rod 24 are threadedly matched to realize the movement of the connecting frame 25. Such a setting has the advantages of simple processing and stable transmission.

[0036] like Figures 1 to 3 As shown, the base 22 has a receiving groove 221, and a sliding groove 222 is provided on the side wall of the base 22 corresponding to the notch of the receiving groove 221. The clamping plate 23 is slidably arranged in the sliding groove 222, and the clamping plate 23 and the side wall of the receiving groove 221 are jointly surrounded to form the second clamping cavity 21. Specifically, the provision of the sliding groove 222 further ensures that the clamping plate 23 can move in a preset direction, thereby ensuring that the second pipe can move into place and can be accurately docked with the first pipe.

[0037] like Figures 1 to 4As shown, the first docking portion 10 and the second docking portion 20 are arranged at intervals, and the pipe docking device further includes a protective plate 33 arranged between the first docking portion 10 and the second docking portion 20, and the protective plate 33 is arranged on the outer side of the first clamping cavity 11 and the second clamping cavity 21 in the radial direction. Specifically, "the protective plate 33 is arranged on the outer side of the first clamping cavity 11 and the second clamping cavity 21 in the radial direction" means that when the second pipe extends out of the second clamping cavity 21, the protective plate 33 is arranged on the outer periphery of the part of the second pipe extending out of the second clamping cavity 21, and the function of the protective plate 33 is to prevent the first pipe and the second pipe from being connected (for example, connected by welding), and the debris generated during welding is splashed everywhere.

[0038] like Figures 1 to 4 As shown, the protective plate 33 is an arc-shaped ring plate structure, and the protective plate 33 has a storage position close to the vertical center plane of the first clamping cavity 11 and a protection position away from the vertical center plane of the first clamping cavity 11. The inner surface of the protective plate 33 is provided with a rack, and the second docking portion 20 also includes a gear arranged on the transmission rod 24 and meshing with the rack to drive the protective plate 33 to switch between the storage position and the protection position.

When the protective plate 33 is needed to protect the second pipeline, the protective plate 33 is switched to the protection position, and the protective plate 33 will move upward and outward, thereby protecting the outer periphery of the second pipeline. When the pipeline docking device finishes working, the protective plate 33 is switched to the storage position, and the protective plate 33 will move downward and inward, so as to facilitate the overall storage of the pipeline docking device.

[0039] In addition, if Figures 1 to 4 As shown, the first docking part 10 and the second docking part 20 are arranged at intervals, and the pipeline docking device also includes a second driving motor and a first rotating belt 34 arranged between the first docking part 10 and the second docking part 20. The first rotating belt 34 can be supported below the second pipeline. The second driving motor drives and cooperates with the first rotating belt 34 and drives the first rotating belt 34 to rotate. When the first rotating belt 34 rotates, it drives the second pipeline to rotate. Specifically, the first rotating belt 34 can drive the second pipeline to rotate, so as to facilitate the staff to check whether the pipeline is connected in the circumferential direction, and avoid the situation that some connections are not effectively connected and are not discovered.

[0040] like Figures 1 to 4As shown, the pipeline docking device also includes a transmission member 36 and a second rotating belt 35 arranged between the first docking portion 10 and the second docking portion 20. The second rotating belt 35 and the first rotating belt 34 are located on both sides of the vertical center plane of the first clamping cavity 11. The transmission member 36 is connected between the second rotating belt 35 and the first rotating belt 34 so that when the first rotating belt 34 rotates, the second rotating belt 35 can be driven to rotate synchronously, so that when the second rotating belt 35 rotates, the second pipeline can be driven to rotate. Specifically, the second rotating belt 35 and the first rotating belt 34 respectively support the second pipeline on both sides of the vertical center plane of the first clamping cavity 11 and can drive the second pipeline to rotate along the same rotation direction. The transmission member 36 can be a transmission belt.

[0041] In addition, in other embodiments, an annular groove is provided on the second pipe, and an elastic protrusion is provided on the clamping plate, and the elastic protrusion can be inserted into the annular groove so that the second pipe can move with the clamping plate and the second pipe can rotate relative to the clamping plate. Such an arrangement can ensure that the second pipe can be driven to move when the clamping plate moves, and can also ensure that the second pipe can rotate.

[0042] In addition, if Figure 5 as well as Figure 6 As shown, the present application also provides a second embodiment of the pipe docking device. In the second embodiment, the pipe docking device further includes a pulley block 31 disposed on the side wall of the accommodating groove 221 to reduce the friction force on the second pipe when moving. Specifically, there are multiple pulley blocks 31, thereby further reducing the friction force on the second pipe.

[0043] like Figure 5 as well as Figure 6 As shown, the pipe docking device further includes a butt-pushing member 32, which is disposed on the clamping plate 23 and can be butted against the second pipe so that the second pipe can be driven to move when the clamping plate 23 moves. Specifically, the butt-pushing member 32 can be a support pad made of silicone, and the arrangement of the butt-pushing member 32 can ensure that the second pipe can be driven to move when the clamping plate 23 moves, thereby avoiding slipping.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
