Description

Technical Field

[0001] This utility model belongs to the field of logistics and transportation equipment technology, and in particular relates to an unmanned container transport vehicle. Background Technology

[0002] Unmanned container transport vehicles are automated transportation equipment mainly used in ports, logistics centers, and other similar settings. They can autonomously complete the loading, unloading, and transportation of containers. Traditional unmanned container transport vehicles include modules such as power, navigation, sensors, control, communication, chassis, human-machine interaction, and power management, which work together to achieve their automated transportation functions.

[0003] Among them, the frame module, such as the port unmanned transport vehicle combined frame disclosed in application number CN2021112697276, includes a main frame and an upper frame that is detachably fixed above the main frame. The main frame is characterized by: two parallel outer panels and inner longitudinal beams fixed to the inner surfaces of the two outer panels along their length; a main frame crossbeam for supporting the chassis structure is fixed between the two inner longitudinal beams; the upper frame includes upper frame longitudinal beams and upper frame crossbeams vertically fixed to the upper frame longitudinal beams for supporting containers; the upper frame longitudinal beams are fixed to the outer panels by a detachable fixing structure, suitable for supporting port containers.

[0004] Conventionally, limit structures are welded onto the frame module. However, due to deviations during container landing or damage to these limit structures caused by other accidents, repair and correction are difficult. To address this, an unmanned transport vehicle container landing structure, as disclosed in application number CN2022212102133, uses detachable landing brackets surrounding the frame. Each landing bracket has a supporting ramp. Before landing, the unmanned transport vehicle can flexibly assemble and disassemble the landing brackets to adapt to different container sizes. During landing, the supporting ramps provide precise support and limit the container's position. However, the landing brackets themselves are heavy, and position adjustments require manual assembly and disassembly, which is time-consuming and labor-intensive, thus leaving room for improvement.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Example 1: As shown in the figure, an unmanned container transport vehicle includes a frame 1 and multiple sets of container mounting brackets 2 distributed longitudinally along the frame 1. The frame 1 includes two parallel longitudinal beams 11, which are fixedly connected by multiple crossbeams 12. The container mounting brackets 2 include bidirectional hydraulic cylinders 21 and two connecting plates 22. The bidirectional hydraulic cylinders 21 are fixedly mounted on the crossbeams 12. The two piston rods of the bidirectional hydraulic cylinders 21 correspond one-to-one with the two connecting plates 22 and are detachably connected. The sides of the longitudinal beams 11 are provided with multiple through holes 111 corresponding one-to-one with the connecting plates 22. The other end of the connecting plate 22 passes through the corresponding through holes 111, and the other end of the connecting plate 22 is fixedly provided with an upwardly extending side arm 23. In use, the bidirectional hydraulic cylinders 21 control the two connecting plates 22 to move closer or further apart to adjust the distance between the two side arms 23. This method is suitable for container bodies of different sizes, reduces the need for manual intervention, makes adjustment more convenient, and saves time and effort in operation.

[0023] In this embodiment, the upper end of the side arm 23 is provided with an inclined surface 231 that slopes downward from the outside to the inside, which helps to reduce the impact force that the side arm 23 may be subjected to and extend its service life.

[0024] Example 2: As shown in the figure, the rest is the same as in Example 1, except that the inclined surface 231 is provided with a groove 2311 and a baffle 24. The baffle 24 is attached to the inclined surface 231, and a rotating seat 241 extending into the groove 2311 is fixedly installed on the baffle 24. The side arm 23 away from the frame 1 is provided with a through hole 232 and a telescopic cylinder 25. The through hole 232 is connected to the bottom of the groove 2311. The piston rod of the telescopic cylinder 25 passes through the through hole 232 and extends into the groove 2311. The piston rod of the telescopic cylinder 25 is rotatably engaged with the rotating seat 241 through a rotating shaft. Furthermore, the groove 2311 is located in the central area of ​​the inclined surface 231.

[0025] When the container shifts during unloading, its corners will abut against the baffle 24. When the corners of the container are lower than the height of the groove 2311, the telescopic cylinder 25 is activated, causing the baffle 24 to rotate and fully abut against the side of the container, pushing the container to the correct position and preventing continuous friction between the container and the side arm 23. Compared to using a single side arm 23, the baffle 24 is easier to replace and maintain, helping to reduce costs.

[0026] Furthermore, the baffle 24 is provided with a plurality of protrusions (not shown in the figure) on the side facing the inclined surface 231. The protrusions extend in the vertical direction to improve the structural strength of the baffle 24, making it less prone to bending deformation and extending its service life.

[0027] Example 3: As shown in the figure, the rest is the same as in Example 1, except that a support block 26 is fixedly installed on the upper surface of the connecting plate 22. The support block 26 is located outside the two longitudinal beams 11, and its upper surface is flush with the upper surface of the longitudinal beam 11. One side of the support block 26 is fixedly connected to the side arm 23. In this structure, the support block 26 helps to improve the structural strength of the connection between the side arm 23 and the connecting plate 22, making the side arm 23 less prone to bending deformation and helping to extend its service life. At the same time, the upper surface of the support block 26 is flush with the upper surface of the longitudinal beam 11, jointly supporting the container and helping to improve the load-bearing capacity.

[0028] In this embodiment, the support block 26 is provided with a mounting groove 261 and a gravity sensor 3. The gravity sensor 3 is located at the mounting groove 261 to weigh the container it carries.

[0029] Example 4: As shown in the figure, the rest is the same as in Example 1, except that a convex ring 112 is fixedly provided around the through hole 111 on the side of the longitudinal beam 11 facing the transverse beam 12, and multiple reinforcing ribs 113 are fixedly provided between the outer side of the convex ring 112 and the longitudinal beam 11. By providing the convex ring 112 and the reinforcing ribs 113, the structural strength at the position of the through hole 111 on the longitudinal beam 11 is improved, and the reliability is better. At the same time, the convex ring 112, which is fitted on the outside of the connecting plate 22, can also play a guiding role.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
