It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0037] like Figures 1 to 4 As shown, in this embodiment, the transfer device includes: a transfer body 10, a first locking member 20, a first connecting rod 30 and a first driving member 40. The transfer body 10 has a running wheel 11. The first locking member 20 is arranged on the transfer body 10 and extends upward from the transfer body 10. The first locking member 20 is movably arranged and has a first locking position and a first unlocking position. The first locking member 20 includes a column 21 and a locking block 22 arranged on the column 21. The locking block 22 is arranged at the top of the column 21 and is located above the transfer body 10. The first connecting rod 30 is arranged on the transfer body 10 and connected to the column 21. The first driving member 40 is arranged on the transfer body 10 and is drivingly connected to the first end of the first connecting rod 30. The first driving member 40 drives the first connecting rod 30 to move to drive the first locking member 20 to switch between the first locking position and the first unlocking position.

[0038] According to the technical solution of this embodiment, a first locking member 20 is provided on the transport vehicle body 10. The first locking member 20 is movably provided and has a first locked position and a first unlocked position. The first locking member 20 includes a column 21 and a locking block 22 provided on the column 21. A first connecting rod 30 is provided on the transport vehicle body 10 and is connected to the column 21. A first driving member 40 is provided on the transport vehicle body 10 and is drivingly connected to the first end of the first connecting rod 30. The first driving member 40 can drive the first connecting rod 30 to move and thereby drive the first locking member 20 to switch between the first locked position and the first unlocked position. Through the above arrangement, when the transport device is transporting a container, the container can be placed on the transport vehicle body 10. When the container is placed on the transport vehicle body 10, the locking block 22 can be inserted into the lock seat on the container. The first driving member 40 can drive the first connecting rod 30 to move, thereby driving the column 21 to move, thereby driving the locking block 22 to move. In this way, the first locking member can be switched from the first unlocked position to the first locked position, thereby stably connecting the container and the transport vehicle body 10. This can effectively ensure the stability of the transfer vehicle body and the container. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the container and the vehicle body are prone to deflection or falling from the vehicle body.

[0039] Specifically, in this embodiment, the locking block 22 is a bar-shaped block, and the lock seat on the container is a bar-shaped hole. The bar block can be inserted into the bar hole after being aligned with the bar hole. At this time, when the first driving member 40 drives the first connecting rod 30 to move, the bar block can rotate, so that the bar block can cooperate with the container limit, thereby achieving locking.

[0040] like Figures 3 to 7 As shown, in this embodiment, both the first locking member 20 and the first connecting rod 30 are rotatably arranged, with the axis of the first locking member 20 and the axis of the first connecting rod 30 perpendicular to each other, and the column 21 connected to the middle portion of the first connecting rod 30. The rotational characteristics of the first locking member 20 and the first connecting rod 30, coupled with the perpendicular connection between the two axes, ensure smooth and precise locking and unlocking of the first locking member 20. This improves the response speed and positioning accuracy of the first locking member 20, while also enhancing the stability and reliability of the transfer device.

[0041] like Figure 3 and Figure 4 As shown, in this embodiment, the transfer device further includes a second connecting rod 51 and a guide structure 52 provided on the transfer vehicle body 10. The guide structure 52 cooperates with the second connecting rod 51 for guidance, and the first end of the second connecting rod 51 movably cooperates with the second end of the first connecting rod 30. The cooperation between the guide structure 52 and the second connecting rod 51 achieves precise guidance of the connecting rod movement, ensuring the stability and accuracy of the connecting rod during movement.

[0042] Specifically, under the action of the guide structure 52 , the second connecting rod 51 makes the movement of the second connecting rod 51 more stable, which can make the movement of the first connecting rod 30 more stable.

[0043] like Figure 3 and Figure 4 As shown, in this embodiment, the second end of the first connecting rod 30 is provided with a strip groove 31 extending along the length of the first connecting rod 30, and the first end of the second connecting rod 51 is provided with a sliding block 511, which is inserted into the strip groove 31. The cooperation between the strip groove 31 and the sliding block 511 enables the second connecting rod 51 to slide on the first connecting rod 30, thereby achieving flexible adjustment and control of the movement of the first connecting rod 30 and the second connecting rod 51. This also ensures the flexibility of the movement of the first connecting rod 30 and the second connecting rod 51 and the precision of the cooperation between the first connecting rod 30 and the second connecting rod 51.

[0044] It should be noted that the cooperation between the strip groove 31 and the sliding block 511 can prevent the first connecting rod 30 and the second connecting rod 51 from being stuck.

[0045] like Figures 1 to 7 As shown, in this embodiment, the transfer device also includes a third connecting rod 53 and a second locking member 54 disposed on the transfer vehicle body 10. The third connecting rod 53 is movably connected to the second end of the second connecting rod 51. The second locking member 54 is connected to the second end of the third connecting rod 53. The second locking member 54 has a second locked position and a second unlocked position. The first driving member 40 drives the first connecting rod 30 to rotate to drive the second connecting rod 51 to move. The movement of the second connecting rod 51 can drive the third connecting rod 53 to swing and switch the second locking member 54 between the second locked position and the second unlocked position. The first driving member 40 drives the first connecting rod 30 to rotate, thereby driving the second connecting rod 51 to move. The swinging of the third connecting rod 53 controls the switching of the second locking member 54 between the second locked position and the second unlocked position. This achieves coordinated control of the second locking member 54 and the first locking member 20, thereby improving the flexibility and safety of the second locking member 54 and the first locking member 20.

[0046] like Figures 1 to 7 As shown, in this embodiment, the transfer device further includes a support structure 60 that is rotatable about its longitudinal centerline. The support structure 60 has an initial position along the width of the transfer vehicle 10. This arrangement utilizes the rotatable nature of the support structure 60, allowing the support structure 60 to be adjusted in the width direction as needed to accommodate different transport routes. This further improves the adaptability and stability of the transfer device during transport.

[0047] like Figures 1 to 4As shown, in this embodiment, the support structure 60 includes a support body and first and second position-limiting members provided on the support body. The first and second position-limiting members are provided at both ends of the support body, respectively. By providing the first and second position-limiting members at both ends of the support body, the lateral movement of the container is restricted, ensuring the stability and safety of the container during transportation.

[0048] like Figures 1 to 4 As shown, in this embodiment, the first limiting member includes a first baffle and a second baffle, the first baffle is connected to the first end of the support body, the second baffle is connected to the end of the first baffle and is connected to the support body, and a first preset angle is formed between the second baffle and the first baffle;

[0049] like Figures 1 to 4 As shown, in this embodiment, the second stopper includes a third stopper and a fourth stopper. The third stopper is connected to the third end of the support body, and the fourth stopper is connected to the end of the third stopper and is connected to the support body. A second predetermined angle is formed between the fourth stopper and the third stopper. This arrangement can limit the container in two directions, thereby providing a better position-limiting effect and ensuring the safety of the container during transportation.

[0050] like Figure 1 、 Figure 2 as well as Figure 7 As shown, in this embodiment, the transfer vehicle body 10 is provided with a first guide rail portion 12, and the support structure 60 is provided with a first guide wheel 61. The first guide wheel 61 is provided at a first end of the support structure 60 and cooperates with the first guide rail portion 12 for guidance. The guiding cooperation between the first guide wheel 61 and the first guide rail portion 12 ensures the stability and accuracy of the support structure 60 during the rotation process.

[0051] Furthermore, the cooperation between the first guide wheel 61 and the first guide rail portion 12 can support the support structure 60 , thereby making the support structure 60 more stable when supporting the container.

[0052] like Figure 1 、 Figure 2 as well as Figure 7 As shown, in this embodiment, the first guide rail portion 12 is arc-shaped, and the diameter of the first guide wheel 61 gradually increases from the middle of the support structure 60 to the first end of the support structure 60; a second guide rail portion 13 is also provided on the transfer vehicle body 10, and a second guide wheel 62 is provided on the support structure 60. The second guide wheel 62 is provided at the second end of the support structure 60 and cooperates with the second guide rail portion 13 for guidance.

[0053] By gradually increasing the diameter of the first guide wheel 61 and the arc-shaped design of the first guide rail portion 12 , as well as the guiding cooperation between the second guide wheel 62 and the second guide rail portion 13 , smooth transition and precise guidance of the support structure 60 during rotation are achieved.

[0054] Specifically, if Figure 7 As shown, in this embodiment, the distance between the first guide rail portion 12 and the transfer vehicle body 10 gradually decreases from the middle of the support structure 60 to the first end of the support structure 60. The distance between the second guide rail portion 13 and the transfer vehicle body 10 gradually decreases from the middle of the support structure 60 to the second end of the support structure 60. The coordination between the first guide rail portion 12 and the first guide wheel 61 and the coordination between the second guide rail portion 13 and the second guide wheel 62 further stabilizes the position of the first guide wheel 61 and the second guide wheel 62, making derailment less likely.

[0055] Moreover, the above arrangement can achieve force dispersion, that is, the direction of the force on the first guide wheel 61 is inclined, that is, the force can be converted into horizontal force and vertical force, so that the support structure 60 can support heavier containers.

[0056] The force at the second guide wheel 62 is the same as the force at the first guide wheel 61 .

[0057] like Figure 1 、 Figure 2 、 Figure 5 as well as Figure 7 As shown, in this embodiment, the transfer device also includes a transmission structure 71 and a second driving member 72. The transmission structure 71 is arranged between the second driving member 72 and the rotating shaft of the support structure 60. The second driving member 72 can drive the support structure 60 to rotate through the transmission structure 71.

[0058] The second driving member 72 cooperates with the transmission structure 71 to achieve precise control of the rotation of the support structure 60. This can improve the response speed and rotation accuracy of the support structure 60, thereby enhancing the flexibility and stability of the transfer device during transportation.

[0059] like Figure 1 、 Figure 2 、 Figure 5 as well as Figure 7 As shown, in this embodiment, the transmission structure 71 includes a first gear 711 and a second gear 712. The first gear 711 is arranged on the rotating shaft of the support structure 60, and the second gear 712 is arranged on the driving shaft of the second driving member 72. The first gear 711 and the second gear 712 are meshed and arranged. The number of teeth of the first gear 711 is greater than the number of teeth of the second gear 712.

[0060] The meshing arrangement of the first gear 711 and the second gear 712 can more stably control the rotation of the support structure 60 and can make the rotation angle of the support structure 60 more precise.

[0061] Furthermore, through the gear ratio of the first gear 711 and the second gear 712 , the rotation of the support structure 60 is decelerated and torque increased, thereby ensuring the stability and accuracy of the rotation process.

[0062] Specifically, the ratio of the number of teeth of the first gear 711 to the number of teeth of the second gear 712 is between 2 and 6. In this embodiment, the ratio of the number of teeth of the first gear 711 to the number of teeth of the second gear 712 is 3.

[0063] Of course, the above ratio can also be 2.5, 3.5, 4.5, 5, 5.5 or other values.

[0064] Specifically, in this embodiment, the transfer device also includes lift cylinders. When the road surface is uneven laterally, the axles swing to compensate. When the road surface is uneven vertically, the group of lift cylinders provides longitudinal compensation. On sloped roads, the lift cylinders can be adjusted to achieve leveling.

[0065] The transfer vehicle body 10 has high rigidity and strong bending moment resistance. When subjected to torsion, it is flexible and does not deform under impact loads. The overall strength and rigidity of the vehicle have sufficient margins, and the vehicle can carry a uniform load.

[0066] The support structure 60 is equipped with a tapered roller bearing, which swings around the axis of rotation to accommodate uneven longitudinal surfaces. The turntable uses a single-row ball slewing bearing. Both the inner and outer rings of the slewing bearing are forged from high-quality alloy steel, providing a strong load-bearing capacity.

[0067] According to another aspect of the present application, a combined transport device is provided. Figure 8 As shown, the combined transfer device of this embodiment includes two transfer devices, which are arranged in a front-to-back manner, wherein the transfer device is the above-mentioned transfer device.

[0068] The above arrangement, through the combination of two transfer units, enables efficient loading and transport of containers of varying sizes, as well as flexible operation in complex environments. This improves the flexibility and efficiency of the combined transfer unit when handling containers of various sizes, reduces the risk of deviation during cornering, and enhances its adaptability in complex environments.

[0069] It should be noted that the two transfer devices include a first identification structure and a second identification structure respectively.

[0070] adjusting a position of the first transfer device according to a first recognition result of the first recognition structure so that the first transfer device moves below the first end of the container;

[0071] adjusting the position of the second transfer device according to the second recognition result of the second recognition structure so that the second transfer device moves below the second end of the container;

[0072] When the container is placed on the two transfer devices, the first locking member 20 and the second locking member 54 of the two transfer devices are controlled to lock the container;

[0073] According to the curvature of the transport path, the rotation direction and rotation angle of the support structure 60 are controlled by the second driving member 72 .

[0074] The above design utilizes the first and second identification structures to obtain container location information. The coordinated operation of the first locking element 20 and the second locking element 54 achieves precise support and stable transportation of the container. This provides greater flexibility and safety when navigating routes with varying curvatures and accommodating containers of varying sizes.

[0075] Specifically, the combined transfer device of this embodiment has a turning scene, a parking scene, and an unloading scene.

[0076] Turning scene:

[0077] When the combined transfer device turns, the support structure 60 works in coordination with the steering system of the combined transfer device, prompting the front and rear transfer devices to work closely together to complete the turning action, thereby effectively reducing the turning radius and improving the steering flexibility and passability of the combined transfer device in narrow spaces.

[0078] Parking scene:

[0079] When parking containers, the combined transfer device can more flexibly adjust the placement of the containers, and can cooperate with the steering system of the combined transfer device to ensure that the container parking position is accurate, meet diverse parking needs, and improve site space utilization.

[0080] Dressing scene:

[0081] During the loading and unloading operation, the combined transfer device can automatically and accurately adjust the position of the lock seat according to the actual position of the container corner fitting, effectively compensating for the deviation between the lock seat and the container corner fitting after the transfer device is docked, ensuring the efficiency and accuracy of the loading and unloading process.

[0082] The specific working process is as follows: the position of the corner fittings of the unloading container is accurately located through the visual system, and the collected data is transmitted to the PLC (programmable logic controller). After the control operation, the PLC issues an instruction to the second driving member 72, and the second driving member 72 drives the second gear 712 to operate, thereby driving the support structure 60 to accurately adjust the position of the lock seat.

[0083] After the unloading operation is completed, the control system immediately controls the first driving member 40 to work, so that the first locking member 20 enters the first locking position and the second locking member 54 enters the second locking position, thereby ensuring a close connection between the container and the transfer device and ensuring transportation safety.

[0084] It should be noted that when turning, since the support structure 60 can rotate, the relative position between the container and the transfer vehicle body 10 can change, so that the transfer vehicle body 10 can turn before the container. Since the first end of the container is supported on the support structure 60, the support structure 60 can rotate relative to the transfer vehicle body 10, so that the direction of the container can remain unchanged first, which can effectively reduce the turning radius of the container.

[0085] In the description of the present invention, it should be understood that "plurality" refers to a quantity of two or more than two. 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 accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the devices or components 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 outline of each component itself.

[0086] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. 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 figures. For example, if the device in the 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.

[0087] 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. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0088] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
