It is used in smart warehouse projects across various industries. However, in light shuttle projects, the horizontal paths of the shuttles may intersect, making the coordination of intersecting tracks particularly critical. Even the slightest deviation can cause noise during operation, or even jolt the shuttle, potentially causing the cargo carried by the shuttle to shift or fall. Therefore, a meshing structure for the shuttle track at these intersections is required. Utility Model Content

[0022] The following provides a detailed description of the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model and do not limit the present utility model.

[0024] See Figures 1-5The ratchet structure for the walking track of a light shuttle car shown in the figure. The ratchet structure includes a square support member 1 and four tracks 2 arranged radially. Two adjacent tracks 2 are perpendicular to each other. At the four corner positions of the square support member 1, there are limit guide chutes 11 extending towards the center direction. On the bottom surface of the track 2, there is a limit reverse slide bar 3 that fits with the limit guide chute 11. At the center of the square support member 1, there is a positioning cylinder 9. The docking end 8 of the track 2 has a 90° angle male groove. The side walls of two adjacent docking ends 8 are in contact with each other. At least two countersunk holes 16 are provided at one end of the track 2 close to the square support member 1. On the square support member 1, there is a through hole 13 coaxial with the countersunk hole 16. A countersunk screw 6 passing through the through hole 13 is installed in the countersunk hole 16. The upper surface of the countersunk screw 6 is flush with the upper surface of the track 2. A nut 12 is sleeved on the lower end of the countersunk screw 6. At the end of the docking end 8, there is a positioning arc groove 14 that fits with the positioning cylinder 9.
[0025] By implementing the above technical solution, the bottom surface of the square support member 1 in the present utility model is fixed by welding or bolt installation on the structural beam of the overall shelf. During assembly, the docking ends 8 of the four tracks 2 in four directions are sequentially inserted along their respective limit guide chutes 11. When the insertion reaches the positioning arc groove 14 abuts against the positioning cylinder 9, the installation is in place. After each track 2 is installed in place, it is locked by inserting the countersunk screw 6 into the countersunk hole 16 and the through hole 13 in sequence and then tightening with the nut 12. After all four tracks 2 are installed in place, the side walls of the respective docking ends 8 are in contact with each other in sequence. When installing this ratchet structure, the vertical direction and the horizontal left and right positions are limited through the cooperation of the limit reverse slide bar 3 and the limit guide chute 11, and the advancing direction is limited through the cooperation of the positioning cylinder 9 and the positioning arc groove 14, thus realizing the rapid installation of the track 2. Also, due to the cooperation of the countersunk hole 16 and the countersunk screw 6, and the contact cooperation of the respective docking ends 8, after the track 2 is locked and installed on the square support member 1 through the countersunk screw 6 and the nut 12, the surface of the countersunk screw 6 does not protrude from the track 2's rail bearing surface after installation, and the flatness of the connection position of each track 2 is high, without affecting the normal walking of the shuttle car.
[0026] In this embodiment, in order to further provide a structure of the limit guide groove and the limit reverse slide bar, the limit guide chute 11 is a T-shaped groove or a dovetail groove, and the limit reverse slide bar 3 is a T-shaped bar or a dovetail bar corresponding to the limit guide chute 11.
[0027] In this embodiment, an internal hexagonal groove 7 is provided in the middle of the countersunk screw 6. Through such a setting, when disassembling and assembling the countersunk screw 6, a corresponding internal hexagonal screwdriver can be used.
[0028] In this embodiment, side baffles are provided on both sides of the track 2; two adjacent side baffles are butted against each other. Through such a setting, the two sides of the track 2 have a limiting effect, preventing the wheels of the shuttle car from disengaging from the track 2 when rolling, especially at the turning points of the cross-junction.
[0029] In this embodiment, in order to further provide a side baffle structure, the side baffle includes an extension plate 4 fixedly connected to both sides of the track 2, and an upper baffle 5 fixedly connected to the extension plate 4. A docking plate 10 is fixedly connected to the inner end of the upper baffle 5, and two adjacent docking plates 10 are butted against each other. Through the setting of the extension plate 4, the movement margin of the wheels is increased at the cross-junction position, facilitating the steering operation. Of course, in order to prevent the wheels from falling, the distance between the upper baffle 5 and the side of the track 2 should not exceed half of the width of the wheels. In addition, through the setting of the docking plate 10, the two adjacent docking plates 10 are butted against each other to form a closure, preventing the wheels from being blocked during the commutation.
[0030] In this embodiment, the distance between the docking plate 10 and the side of the track 2 gradually increases in the direction towards the docking end 8, and a docking inclined surface 15 is provided at the end of the docking plate 10. Through such a setting, a flared side structure is formed on both sides of each track 2 at the end position, enabling the wheels to better enter the corresponding tracks 2 after commutation.
[0031] In this embodiment, the upper end of the positioning cylinder 9 does not protrude above the upper surface of the track 2. Of course, as an optimal way: the upper end of the positioning cylinder 9 is set to be flush with the rail-bearing surface of the track 2.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0033] In addition, it should be noted that, in the various specific technical features described in the above specific embodiments, they can be combined in any suitable way without conflict. In order to avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.
[0034] In addition, any combination can be made between various different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
