Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a four-way shuttle vehicle used for logistics transfer. Background Art

[0002] The four-way shuttle is a highly automated logistics equipment that can move in both the x-axis and y-axis of the shelf and has the characteristic of being able to travel in four directions without turning. This design enables it to effectively utilize warehouse space, improve warehouse storage density, and be more efficient and flexible when handling goods. The four-way shuttle can reach any location in the warehouse via the tracks on the shelf, realizing the automated handling and transportation of goods. The horizontal movement and storage and retrieval of goods within the shelf can be completed by only one four-way shuttle. Combined with the elevator layer change, the degree of system automation is greatly improved. The four-way shuttle has a wide range of application scenarios, including smart factory workshop line-side warehouses, smart intensive storage finished product warehouses, semi-finished product warehouses, raw material warehouses, logistics distribution center warehouses and unmanned dark warehouses. They can automatically switch 90 degrees between longitudinal storage lanes and lateral transfer channels, suitable for warehouse storage modes in complex terrain environments. They are generally suitable for food, beverages, dairy products, medical products, fine chemicals and other products, and are suitable for low-temperature cold chain logistics.

[0003] When the four-way shuttle is transferring goods, the pallet is lifted up by the lifting plate so that the pallet is out of contact with the ground, and the four-way shuttle can then move the goods. However, when the existing four-way shuttle is used in a cold storage warehouse, due to the problem of ice forming in the cold storage warehouse, ice may form on the bottom of the pallet. After the pallet contacts the lifting plate on the four-way shuttle, the friction force is insufficient, which may cause the pallet to slide when the four-way shuttle stops. In severe cases, the pallet and the goods may fall off the four-way shuttle, causing damage to the goods. In order to solve this technical problem, the utility model proposes a four-way shuttle for logistics transfer. Utility Model Content

[0004] The main purpose of the present invention is to provide a four-way shuttle vehicle for logistics transfer, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A four-way shuttle vehicle for logistics transfer, comprising a four-way shuttle vehicle body and a lifting plate. The lifting plate is arranged above the four-way shuttle vehicle body.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a four-way shuttle vehicle for logistics transfer includes a four-way shuttle vehicle body 1 and a lifting plate 2. The lifting plate 2 is arranged above the four-way shuttle vehicle body 1. The pallet is lifted by the upward lifting of the lifting plate 2. After the pallet is lifted, it is separated from the track in contact, and the four-way shuttle vehicle body 1 can drive the pallet and the goods above to move positions.

[0024] The inner side of the lifting plate 2 is provided with a slideway 3. The inner wall of the slideway 3 is slidably connected with a sliding seat 4. The stability of the sliding seat 4 is maintained through the slideway 3. The upper surface of the sliding seat 4 is connected with a first support seat 5. One side of the first support seat 5 is connected with a pushing plate 6. The sliding seat 4 provides a supporting force for the pushing plate 6 through the first support seat 5. There are four slideways 3 on each lifting plate 2, which are respectively located at both ends of the lifting plate 2. The slideway 3 has a corresponding number of sliding seats 4.

[0025] The inner wall of the sliding seat 4 is slidably connected with an adjusting block 7. By moving the position of the adjusting block 7, the moving distance of the sliding seat 4 is adjusted so that the two sliding seats 4 have the same moving distance. The lower surface of the adjusting block 7 is connected with a frame 8. The adjusting block 7 receives the power of the connecting rod 10 through the frame 8. The lower surface of the lifting plate 2 is rotatably connected with a swing arm 9. The inner wall of the swing arm 9 is rotatably connected with a connecting rod 10. The other end of the connecting rod 10 is rotatably connected with the inner wall of the frame 8. An electric push rod 11 is arranged below the lifting plate 2. The output end of the electric push rod 11 is rotatably connected with the inner wall of the swing arm 9. Taking the electric push rod 11 as the power source, after the electric push rod 11 pushes the connecting rod 10 to change the angle, it drives the connecting rod 10 to move the position. By moving the position of the connecting rod 10, the position of the sliding seat 4 is adjusted in gear, so that the sliding seat 4 drives the push plates 6 at both ends of the lifting plate 2 to move the position.

[0026] The lower surface of the lifting plate 2 is connected with a second support seat 12. The inner wall of the second support seat 12 is rotatably connected with the fixed end of the electric push rod 11. When the electric push rod 11 pushes the connecting rod 10 to move the position, the electric push rod 11 will generate an angular change. Through the rotational support of the second support seat 12, the angular difference generated by the electric push rod 11 is compensated.

[0027] The outer surface of the push plate 6 is connected with a plurality of reverse teeth 13, and the reverse teeth 13 have an inclined angle. The plurality of reverse teeth 13 are arranged at equal distances. The pallet contacts the tray through the reverse teeth 13 to increase the friction force, further improving the stability of the tray.

[0028] The outer surface of the sliding seat 4 is connected with a support frame 14. The inner side of the support frame 14 is connected with a support shaft 15. The outer surface of the support shaft 15 is rotatably connected with a roller 16. The support shaft 15 supports the roller 16 to maintain the stability of the roller 16 during rotation. A chute 17 is opened on the inner side of the lifting plate 2. The inner wall of the chute 17 is in contact with the outer surface of the roller 16. The roller 16 is supported and guided through the chute 17. The rolling function of the roller 16 reduces the friction between the sliding seat 4 and the lifting plate 2.

[0029] The inner side of the sliding seat 4 is rotatably connected with a lead screw 18. The outer surface of the lead screw 18 is threadedly connected with the inner side of the adjusting block 7. By rotating the lead screw 18, the position of the adjusting block 7 is changed. After the adjusting block 7 moves the position, the moving position of the sliding seat 4 is changed. Both ends of the lifting plate 2 are detachably connected with a plug 19. A through hole 20 is opened on the inner side of the plug 19, and the through hole 20 is symmetrical with the lead screw 18. The movement position of the sliding seat 4 is blocked and restricted through the plug 19. When the sliding seat 4 fails, the plug 19 is removed to facilitate taking out the sliding seat 4 for maintenance operations on the sliding seat 4. The end of the lead screw 18 is an inner hexagonal groove. It is convenient to drive the lead screw 18 to rotate by passing a hexagonal wrench through the through hole 20.

[0030] It should be noted that during the actual use of the device, first, the lifting plate 2 rises upward. After the lifting plate 2 rises, it lifts the tray together with the goods. Then, the electric push rod 11 is activated to drive the swing arm 9 to rotate. The rotation of the swing arm 9 drives the connecting rod 10 to move. The connecting rod 10 drives the adjusting block 7 to move. The connecting block simultaneously drives the sliding seat 4 to move. The sliding seat 4 drives the push plate 6 to move through the first support seat 5. Subsequently, the push plate 6 contacts the pallet.
