[0002] At present, most container transport vehicles are only capable of transporting one container per vehicle for large-sized containers, such as 40-foot containers. There are also some equipment that can realize double-layer container transportation, such as a double-layer container transportation equipment and container loading and unloading method disclosed in the Chinese invention patent with application number 202211536495.0, in which a lifting guide mechanism composed of a lifting mechanism and a guide mechanism is installed at each end of the frame body, and the guide mechanism includes four right-angle guide groove mechanisms arranged at the four corners of the container; the position of the frame body between the two lifting guide mechanisms constitutes a single-layer box position, and when the lifting mechanism is lifted, the top of the two lifting mechanisms constitutes a double-layer box position; the fixed pull rod is fixed to the four right-angle guide groove mechanisms in a rectangular structure, and one end of the telescopic pull rod is fixed to the lifting mechanism or the right-angle guide groove mechanism, and the other end is fixed to the side of the frame body; the fixed pull rod and / or the telescopic mechanism form a supporting force from the side of the container, thereby realizing double container transportation while ensuring the transportation safety performance of the container, and significantly improving the loading and unloading efficiency of the terminal. However, at present, such equipment that can realize double-layer container transportation generally has the problem of heavy weight. And with the continuous development of communication technology, unmanned driving technology and new energy technology, more and more new energy unmanned container transport vehicles are put into use. Since the battery pack of new energy unmanned container transport vehicles is relatively heavy, in order to maintain the carrying capacity, the requirements for the lightweight of the equipment installed on them are higher, and it is difficult to combine with these heavy equipment to achieve the effect of double-layer container transportation. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a lightweight AGV bracket for double-layer containers, which can realize the simultaneous transportation of double-layer large containers and can be disassembled and assembled using a forklift, and an unmanned container transport vehicle having the bracket.

DETAILED DESCRIPTION

[0007] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0008] Please refer to Figures 1 to 8 , an AGV bracket for double-layer containers, comprising a base 1 and a bracket 2 rotatably connected to the base 1; a forklift operation interface 3 is provided on the base 1; the base 1 limits the position of the lower container in the width direction, and the bracket 2 limits the position of the upper container in the width direction. In order to limit the position of the lower and upper containers, two AGV brackets need to be used at the same time, that is, two AGV brackets are set on the vehicle body or the main support frame used to transport the container, and the two AGV brackets are located at both ends of the length direction of the container.

[0009] From the above description, it can be seen that the beneficial effects of the present invention are: by using the AGV bracket provided by the present application, double-layer loading of large-sized containers (such as 40 feet) can be achieved, effectively increasing the number of containers transported in a single trip, reducing logistics costs, and improving transportation efficiency. It has great advantages in high-intensity operations, and can ensure the stability and safety of the container during loading and unloading and transportation. At the same time, the AGV bracket provided by the present invention can be installed and disassembled by a forklift, does not rely on large-scale lifting equipment, is easy to use, and will not affect the normal use of the original transport AGV.

[0010] Furthermore, the forklift operation interface 3 is arranged at a position of about 1 / 2 of the height direction of the base 1, which can ensure sufficient loading and unloading space without increasing the difficulty of loading and unloading. In order to reduce weight, the base 1 is preferably constructed in the form of longitudinal beams, cross beams and reinforcing beams. At this time, the forklift operation interface 3 is arranged in the middle of the longitudinal beam. The forklift operation interface 3 includes a cross frame 31 and reinforcing frames 32 arranged on both sides of the cross frame 31. In order to improve the stability of transportation while ensuring lightweight, the number of reinforcing frames 32 is preferably set to four, which are respectively arranged at the edges of the two sides of the cross frame 31, and the reinforcing frames 32 are triangular columnar, and their two right-angled faces are respectively connected to the cross frame 31 and the longitudinal beam of the base 1.

[0011] Furthermore, it also includes a hydraulic support 4, the fixed end of which is connected to the base 1, and the movable end is connected to the bracket 2. That is, the piston of the hydraulic support 4 is connected to the bracket 2, specifically, it is hinged.

[0012] It can be seen from the above description that the rotation of the bracket relative to the base is achieved through the movement of the piston rod of the hydraulic support, that is, the opening and closing of the AGV bracket is achieved.

[0013] Furthermore, the base 1 includes at least two first support members 11, and the first support members 11 include two first support surfaces 111 vertically connected to each other. The two first support members 11 abut against the corners of the lower container, and the first support surfaces 111 extend along the height direction of the container. The first support surfaces 111 abut against the side walls of the lower container to limit the position of the lower container. When there are only two first support members 11, the two first support members 11 are preferably able to abut against two different corners. When there are more than two first support members 11, multiple first support members 11 can be continuously or discontinuously arranged at the same corner along the height direction of the container, so that the lower container can be limited between the two bases during transportation.

[0014] Furthermore, a first guide mechanism 12 is provided on the top of the base 1. The first guide mechanism includes two first guide surfaces 121 that are connected to each other and arranged obliquely. One end of the first guide surface 121 is connected to the upper end of the first support surface 111, and the other end is arranged toward the outside of the base 1. The angle between the first guide surface 121 and the extension surface of the first support surface 111 is 30°, and the height of the first guide surface 121 in the vertical direction is 250-350 mm. For example, when the container is 40 feet, it can be 270 mm. The first support member 11 and the first guide mechanism form a funnel structure with a larger upper portion and a smaller lower portion, and the first guide mechanism 12 plays a role in guiding the lower container to fall.

[0016] The movable end of the hydraulic support 4 is used to drive the driving connecting rod 215 to move. The support rod is provided with a limit sensing device 23, which is used to sense the distance between the support rod and the connecting rod 214, and then determine whether the bracket 2 is in an expanded or closed state. The setting of the limit sensing device 23 enables the AGV bracket to be used in conjunction with an unmanned control system, and the state of the AGV bracket can be identified and controlled by the system.

[0017] It can be seen from the above description that, through the movement of the piston rod of the hydraulic support, the connecting rod and the driving connecting rod are driven to approach the support rod, and at the same time the bumper is deployed outward, thereby providing a larger space for lifting the container.

[0018] Furthermore, two support rods are included, namely a first support rod 211 and a second support rod 212, one end of the first support rod 211 is connected to one end of the bumper 213 close to the connecting rod 214, and one end of the second support rod 212 is connected to the middle of the bumper 213. The ends of the first support rod 211 and the second support rod 212 connected to the base 1 are jointly arranged on an ear plate, and the ear plate is connected to the corresponding ear plate of the base 1. The limit sensing device 23 is arranged on the first support rod 211, and a limit member 24 is provided between the first support rod 211 and the connecting rod. The limit member 24 includes a limit plate 241 and a limit pin 242. A long hole is provided on the limit plate 241. The limit pin 242 is connected to the first support rod 211. The limit plate 241 is connected to the connecting rod 214. The limit pin 242 is located in the long hole and passes through the long hole. The limit pin 242 can slide in the long hole. A nut can be further provided on the limit pin 242 to prevent the limit pin 242 from falling out.

[0019] Furthermore, two second guiding mechanisms 25 are detachably provided on the bracket 2 .

[0020] Further, the second guide mechanism 25 is connected to the bumper 213, that is, it is arranged at the end of the bumper 213 that is not connected to the connecting rod 214; the second guide mechanism 25 includes two second supporting surfaces 251 connected to each other vertically, and two second guiding surfaces 252 connected to each other and inclined, one end of the second guiding surface 252 is connected to the upper end of the second supporting surface 251, and the other end is arranged toward the outside of the bracket 2. The angle between the second guiding surface 252 and the extension surface of the second supporting surface 251 is 30°, and the height of the second guiding surface 252 in the vertical direction is 200~300mm. For example, when the container is 40 feet, it can be 240mm.

[0021] When the second guide mechanism 25 is not provided, the bumper 213 can play a role in limiting the position of the upper container. When the second guide mechanism 25 is provided, the second support surface 251 and the second guide surface 252 form a funnel structure with a larger upper portion and a smaller lower portion, the second support surface 251 abuts against the corner of the upper container, the second support surface 251 extends along the height direction of the container, and the second support surface 251 abuts against the side wall of the upper container to limit the position of the lower container, and the second guide surface 252 plays a role in guiding the upper container to fall.
