[0028] The technical solutions of the present application will be further specifically described below through embodiments and in combination with the drawings.

[0029] Referring to Figures 1 to 6 , a chassis for a container stacking device, comprising a frame 11 for extending into a container, the upper side of the frame 11 is provided with a conveying mechanism 12 for conveying articles, the length direction of the frame 11 is parallel to the conveying direction of the conveying mechanism 12, the lower side of the frame 11 is provided with a plurality of Mecanum wheels 13 capable of steering the frame 11 and driving the frame 11 to walk, and the frame 11 is provided with a driving mechanism 14 capable of separately controlling the movement of each Mecanum wheel 13.

[0030] Through the above setting, when the driving mechanism 14 drives the Mecanum wheels 13 to rotate synchronously, the frame 11 moves forward or backward along a straight line; after the frame 11 enters the container, by controlling the rotating speed and rotating direction of each Mecanum wheel 13 through the driving mechanism 14, the orientation of the frame 11 can be rotated in place, realizing the steering of the frame 11 in the narrow container, so that the length direction of the frame 11 is parallel to the length direction of the container; by controlling the rotating speed and rotating direction of each Mecanum wheel 13 through the driving mechanism 14, the frame 11 can move transversely in the container, so that the frame 11 is centered in the container, facilitating stacking.

[0031] Specifically, in use, the driving mechanism 14 drives each Mecanum wheel 13 to rotate synchronously, the frame 11 moves along a straight line and approaches the tail of the container, the tail of the container is provided with a platform, facilitating the Mecanum wheels 13 to drive into the container, after the frame 11 enters the container, the driving mechanism 14 controls the rotating speed and rotating direction of each Mecanum wheel 13, so that the frame 11 is steered in place and is not easy to knock against the inner wall of the container; after the length direction of the frame 11 is parallel to the length direction of the container, the driving mechanism 14 controls the rotating speed and rotating direction of each Mecanum wheel 13 to realize the transverse movement of the frame 11, so that the frame 11 is centered in the container, facilitating stacking.

[0032] As an implementation manner, the driving mechanism 14 includes a plurality of driving motors corresponding to the Mecanum wheels 13 one by one, and the driving motors are connected with the Mecanum wheels 13.

[0033] Each driving motor can control the rotating speed and rotating direction of the corresponding Mecanum wheel 13, so that each Mecanum wheel 13 can be independently controlled and driven, realizing the steering and movement in different directions of the frame 11.

[0034] As an implementation manner, the Mecanum wheels 13 are arranged on opposite sides of the frame 11 in the width direction, and the Mecanum wheels 13 are arranged in sequence along the length direction of the frame 11.

[0035] Through the above setting, the Mecanum wheels 13 stably support the frame 11, so that the frame 11 has good stability.

[0036] As an implementation manner, the frame 11 is provided with a first telescopic mechanism 15 extending in the vertical direction, and the Mecanum wheels 13 are arranged at the lower end of the first telescopic mechanism 15.

[0037] Through the above setting, the height of the frame 11 can be adjusted through the telescoping of the first telescopic mechanism 15, so as to adjust the height of the conveying mechanism 12, facilitating stacking.

[0038] As an implementation manner, at least three first telescopic mechanisms 15 are arranged along the length direction of the vehicle frame 11, and the first telescopic mechanism 15 is arranged at each end of the vehicle frame 11.

[0039] Through the above arrangement, the corresponding Mecanum wheel 13 can be lifted by the first telescopic mechanism 15, which facilitates entering or leaving the container when there is no platform.

[0040] Specifically, in the present application, the first telescopic mechanism 15 can be arranged as a pneumatic cylinder or an oil cylinder. When the tail of the container is not provided with a platform, there is a height difference between the bottom of the container and the ground. When the present application needs to enter the container, the first telescopic mechanism 15 is elongated, the vehicle frame 11 is lifted, and the lower side of the vehicle frame 11 is higher than the bottom of the container. At this time, the first telescopic mechanism 15 supports the vehicle frame 11. When the Mecanum wheel 13 continues to move and the first telescopic mechanism 15 at the front end of the vehicle frame 11 approaches the tail of the container, the first telescopic mechanism 15 at the front end of the vehicle frame 11 is first retracted, so that the corresponding Mecanum wheel 13 and the ground are separated and lifted to a height higher than the bottom of the container. At this time, the front end of the vehicle frame 11 is suspended, and the other first telescopic mechanisms 15 continue to support the vehicle frame 11. Then the Mecanum wheel 13 continues to drive the vehicle frame 11 to move forward, so that the front end of the vehicle frame 11 enters the container. When the first telescopic mechanism 15 and the Mecanum wheel 13 at the front end of the vehicle frame 11 enter the container, the first telescopic mechanism 15 is elongated and the Mecanum wheel 13 contacts the bottom of the container to support the front end of the vehicle frame 11. The Mecanum wheel 13 continues to drive the vehicle frame 11 to move into the container. Similarly, when the other first telescopic mechanisms 15 approach the tail of the container, the corresponding first telescopic mechanisms 15 are retracted and the Mecanum wheel 13 is lifted. At this time, the first telescopic mechanisms 15 at the front and rear ends of the vehicle frame 11 support the vehicle frame 11, and the Mecanum wheel 13 continues to drive the vehicle frame 11 to move into the container. The second telescopic mechanism 164 is elongated and the Mecanum wheel 13 contacts the bottom of the container. In this way, the entire vehicle frame 11 enters the container. Similarly, when the present application exits the container, the Mecanum wheel 13 at the rear end of the vehicle frame 11 first leaves the container, and after the rear end of the vehicle frame 11 is suspended, the first telescopic mechanism 15 in the container supports the vehicle frame 11, while the first telescopic mechanism 15 outside the container is elongated and the Mecanum wheel 13 touches the bottom to support the rear end of the vehicle frame 11. Then the Mecanum wheel 13 continues to drive the vehicle frame 11 to move out of the container, and the Mecanum wheel 13 leaves the container in turn and contacts the ground under the action of the first telescopic mechanism 15 to support the vehicle frame 11, until the entire vehicle frame 11 leaves the container.

[0041] As an implementation form, the vehicle frame 11 is provided with a transverse adjusting mechanism, which comprises a plurality of rotating seats 161 rotatably connected to the lower side of the vehicle frame 11, and a plurality of rollers 162 rotatably connected to the lower side of the rotating seats 161. The vehicle frame 11 is provided with an adjusting motor 163 for driving the rotating seats 161 to rotate so as to adjust the movement direction of the rollers 162. Second telescopic mechanisms 164 are arranged on the opposite sides of the vehicle frame 11 in the width direction and used for pushing the inner wall of the container so as to center the vehicle frame 11.

[0042] Through the above arrangement, when the bottom of the container is uneven, the vehicle frame 11 can be centered by the transverse adjusting mechanism, and the length direction of the vehicle frame 11 is parallel to the length direction of the container. When the application moves in the front-rear direction, the rollers 162 can support the vehicle frame 11, thereby reducing the stress of the Mecanum wheels 13, reducing the wear of the Mecanum wheels 13, and further prolonging the service life of the Mecanum wheels 13.

[0043] Specifically, the second telescopic mechanisms 164 can be air cylinders or oil cylinders. After the vehicle frame 11 enters the container, when the bottom of the container is uneven, the individual Mecanum wheels 13 will be separated from the bottom of the container, and it is not suitable to continue to center the vehicle frame 11 by the Mecanum wheels 13. At this time, the first telescopic mechanism 15 is retracted, the vehicle frame 11 is lowered and the rollers 162 are in contact with the bottom of the container, the adjusting motor 163 drives the rotating seat 161 to rotate, so that the movement direction of the rollers 162 is perpendicular to the length direction of the vehicle frame 11, then the second telescopic mechanism 164 is extended and pushes the inner wall of the container. Under the action of the reaction force of the second telescopic mechanism 164, the rollers 162 rotate and move the vehicle frame 11. When the extension amounts of the second telescopic mechanisms 164 on the opposite sides of the vehicle frame 11 are consistent and both abut against the inner wall of the container, the length direction of the vehicle frame 11 is parallel to the length direction of the container, and the vehicle frame 11 is centered. Finally, the second telescopic mechanism 164 is retracted. In addition, when the application moves in the front-rear direction, the adjusting motor 163 adjusts the movement direction of the rollers 162, so that the movement direction of the rollers 162 is parallel to the front-rear direction of the vehicle frame 11, and the rollers 162 support the vehicle frame 11 together with the Mecanum wheels 13, thereby reducing the stress of the Mecanum wheels 13, reducing the wear of the Mecanum wheels 13, and further prolonging the service life of the Mecanum wheels 13, and reducing the maintenance cost of the application.

[0044] As an implementation form, the vehicle frame 11 is fixedly connected with a mounting seat 111, the adjusting motor 163 is arranged on the mounting seat 111 and connected with a driving gear 112, and the driving gear 112 is engaged with a driven gear 113 fixedly connected with the rotating seat 161.

[0045] The adjusting motor 163 drives the mounting seat 111 to rotate through the driving gear 112 and the driven gear 113, so as to adjust the movement direction of the rollers 162.

[0046] As an implementation manner, the third telescopic mechanism 17 extending in the vertical direction is arranged on the frame 11, and a supporting wheel 171 is rotationally connected to the lower end of the third telescopic mechanism 17, and the movement direction of the supporting wheel 171 is parallel to the length direction of the frame 11.

[0047] Through the above arrangement, the frame 11 in operation is supported by the third telescopic mechanism 17, thereby increasing the stability of the frame 11 and preventing the deformation of the frame 11 during the transportation of the goods; in addition, as the stacking is performed, the Mecanum wheel 13 can drive the frame 11 and the third telescopic mechanism 17 to gradually move outward of the container, thereby realizing the function of moving while stacking.

[0048] Specifically, the third telescopic mechanism 17 can be a pneumatic cylinder or an oil cylinder. During the stacking, the pressure of the goods is transmitted to the frame 11 through the conveying mechanism 12. In reality, in order to reduce the cost, the Mecanum wheel 13 is generally arranged at both ends of the frame 11 and at a position close to the middle of the frame 11. Since the length of the conveying mechanism 12 is large, the third telescopic mechanism 17 is additionally arranged in the middle of the first telescopic mechanism 15. During the stacking, the frame 11 is supported by the third telescopic mechanism 17, thereby reducing the bending moment of the frame 11 and preventing the goods from bending the frame 11. At the same time, as the stacking is performed, the Mecanum wheel 13 can drive the frame 11 and the third telescopic mechanism 17 and the supporting wheel 171 to gradually move outward of the container, thereby realizing the function of moving while stacking.

[0049] As an implementation manner, the frame 11 includes a plurality of mounting portions, the mounting portions are fixedly connected through connecting portions, the connecting portions include at least a plurality of connecting rods 115, both ends of the connecting rod 115 are fixedly connected to the mounting portions, the mounting portions are sequentially arranged along the conveying direction of the conveying mechanism 12, the mounting portions include at least one first mounting portion 114 and at least three second mounting portions 116, the first mounting portion 114 is arranged between two adjacent second mounting portions 116, the lower side of each of the first mounting portion 114 and the second mounting portion 116 is rotationally connected to a rotating seat 161, the first telescopic mechanism 15, the driving mechanism 14 and the second telescopic mechanism 164 are arranged on the second mounting portion 116, and the third telescopic mechanism 17 is arranged on the first mounting portion 114.

[0050] Through the above arrangement, the weight of the frame 11 is small, thereby reducing the production cost.

[0051] Specifically, the mounting part is spliced by steel pipes, has good rigidity and strength, and is used for mounting the first telescopic mechanism 15, the second telescopic mechanism 164, the third telescopic mechanism 17 and other components. When the first telescopic mechanism 15 or the second telescopic mechanism 164 or the third telescopic mechanism 17 operates, the mounting part is not easy to deform under the reaction force. The connecting part includes a plurality of connecting rods 115, which are used for supporting the conveying mechanism 12 and connecting adjacent mounting parts. The connecting part bears less force, so the connecting rod 115 can be used, which reduces the weight of the vehicle frame 11 and reduces the production cost.

[0052] As an implementation manner, the conveying mechanism 12 is provided as a conveying belt. The conveying belt is convenient for long-distance conveying of articles, and the conveying mechanism 12 can also be in other forms such as a transmission roller. The specific form can be adjusted according to the site situation.

[0053] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
