[0002] In recent years, the logistics industry has developed rapidly, and the volume of logistics goods has been continuously increasing. To further achieve logistics automation and improve efficiency, two-way shuttle cars are widely used for the picking and placing of goods. The two-way shuttle car uses a telescopic fork to store and retrieve goods. Currently, most of the two-way shuttle cars in use have two forks, and the farthest reaching distance is limited, making it difficult to pick up the goods deep in the shelf.

[0004] Technical Solution: To solve the above problems, the utility model adopts a box-type shuttle car, which includes a vehicle frame and a fork telescopic mechanism installed on the vehicle frame. The fork telescopic mechanism includes a chain, a chain driving mechanism for driving the chain to rotate, an inner fork, a middle-inner fork, a middle-outer fork, and an outer fork arranged in sequence from inside to outside. The inner fork is fixed on the vehicle frame. The chain is located below the middle-inner fork, and a chain plate matching the chain is provided at the bottom of the middle-inner fork. The inner fork, the middle-inner fork, the middle-outer fork, and the outer fork are slidably connected, and a synchronous belt telescopic system is provided on the inner fork, the middle-inner fork, the middle-outer fork, and the outer fork.

[0025] As Figure 1 shown, a bin-type shuttle car in this embodiment includes a frame 1 and a fork telescopic mechanism installed on the frame. The fork telescopic mechanism includes a chain 2, a chain drive mechanism 3 for driving the chain to rotate, and inner forks 4, middle-inner forks 5, middle-outer forks 6, and outer forks 7 arranged in sequence from inside to outside. As Figure 2 shown, the inner fork 4 is fixed to the frame. The inner fork 4, middle-inner fork 5, middle-outer fork 6, and outer fork 7 are slidably connected. Guide rails 8 are provided on the middle-inner fork 5, middle-outer fork 6, and outer fork 7, and guide grooves 9 matching the guide rails are provided on the inner fork 4, middle-inner fork 5, and middle-outer fork 6. When the middle-inner fork 5, middle-outer fork 6, and outer fork 7 are telescoping, the guide rail 8 slides in the guide groove 9, making the fork telescoping more stable. As Figure 3 shown, a finger 71 and a servo motor 72 are provided on the outer fork 7. The servo motor has a smaller thickness compared to a traditional motor, which is beneficial to reducing the thickness of the fork telescopic mechanism.

[0026] As Figure 4 shown, the chain 2 is located below the middle-inner fork 5, and a chain plate 51 matching the chain 2 is provided at the bottom of the middle-inner fork 5. The chain drive mechanism 3 is a motor, and a sprocket 31 matching the chain 2 is provided on the output shaft of the motor. As Figure 5As shown in the figure, the inner fork 4, the middle inner fork 5, the middle outer fork 6, and the outer fork 7 are provided with a synchronous belt telescopic system. The synchronous belt telescopic system includes a first synchronous belt telescopic device and a second synchronous belt telescopic device at different heights. Among them, the installation height of the first synchronous belt telescopic device is lower than that of the second synchronous belt telescopic device. The first synchronous belt telescopic device includes a first synchronous belt pulley 10, a second synchronous belt pulley 11, and a first synchronous belt 12. The first synchronous belt pulley 10 is installed at one end of the middle inner fork 5 that is inside the vehicle frame when it extends. The second synchronous belt pulley 11 is located at one end of the middle outer fork 6 that is far from the vehicle frame when it extends. One end of the first synchronous belt 12 is fixed to the inner fork 4 through a first synchronous belt clamp 16, and then wound around the first synchronous belt pulley 10 and the second synchronous belt pulley 11 in an S shape in sequence. The other end of the first synchronous belt 12 is fixed to the outer fork 7 through a second synchronous belt clamp 17. The second synchronous belt telescopic device includes a third synchronous belt pulley 13, a fourth synchronous belt pulley 14, and a second synchronous belt 15. The third synchronous belt pulley 13 is located at one end of the middle inner fork 5 that is far from the vehicle frame when it extends. The fourth synchronous belt pulley 14 is located at one end of the middle outer fork 6 that is close to the vehicle frame when it extends. One end of the second synchronous belt 15 is fixed to the inner fork 4 through a third synchronous belt clamp 18, and then wound around the third synchronous belt pulley 13 and the fourth synchronous belt pulley 14 in an S shape in sequence. The other end of the second synchronous belt 15 is fixed to the outer fork 7 through a fourth synchronous belt clamp 19.

[0027] As Figures 6 to 13 shown, on the two-way shuttle vehicle frame of the present utility model, there are provided a motor for driving the movement of the shuttle vehicle and a photoelectric positioning system for obtaining the position information of the shuttle vehicle. After reaching the designated position, the chain drive mechanism 3 is started to drive the chain 2 to rotate, and the middle inner fork 5 is driven to extend outward through the cooperation of the chain 2 and the chain plate 51. The inner fork 4 is fixed to the vehicle frame, so the position of one end of the synchronous belt fixed to the inner fork does not change. When the middle inner fork 5 extends, one end of the first synchronous belt 12 fixed to the inner fork 4 approaches the first synchronous belt pulley 10, the first synchronous belt pulley 10 and the second synchronous belt pulley 11 move away from each other, and the second synchronous belt pulley 11 and one end of the first synchronous belt 12 fixed to the outer fork 7 approach each other, so as to realize the extension of the outer fork 7 relative to the vehicle frame. At the same time, when the middle inner fork 5 extends, one end of the second synchronous belt 15 fixed to the inner fork 4 moves away from the third synchronous belt pulley 13, the third synchronous belt pulley 13 and the fourth synchronous belt pulley 14 approach each other, and the fourth synchronous belt pulley 14 and one end of the second synchronous belt 15 fixed to the outer fork 7 move away from each other, so as to realize the extension of the middle outer fork 6 relative to the vehicle frame. When retraction is required, the movement directions of all components are opposite. In summary, the synchronous telescoping of the middle outer fork 6, the outer fork 7 and the middle inner fork 5 is realized through the synchronous belt telescopic system.

[0028] The present utility model adjusts the telescopic driving mode of the fork from the original double-sided tooth synchronous belt drive to a chain drive, reducing the width of the driving component, thereby providing space for adding one more fork. The original two telescopic forks are increased to three, increasing the overall length of the forks, and enabling easy access to the goods deep in the shelf. At the same time, the fork driving device is installed below the fork, and the synchronous belt telescopic system is arranged above the fork. Through the staggered installation heights, it further helps to reduce the width of the fork telescopic mechanism.
