Description

Technical Field

[0001] This utility model relates to a warehouse automated storage and retrieval system and its forklift structure, and more particularly to a warehouse double-deep automated storage and retrieval system and its forklift structure. Background Technology

[0002] Double-depth automated warehouses (AS / RS) are a warehousing solution that increases the depth of storage racks to improve warehouse space utilization. Traditional AS / RS typically use a single-depth layout, meaning that each rack has only one row of goods that can be directly accessed. Double-depth AS / RS, on the other hand, designs the racks to be two rows deep, allowing more goods to be stored in the same area of ​​land. Double-depth AS / RS usually require the use of specialized forklifts.

[0003] When handling the second deep cargo unit, in order to avoid interference between the fork and the aisle side beam, the existing double-depth automated warehouse has aisle side beams that are lower than non-aisle side beams, resulting in some wasted space. At the same time, existing double-depth automated warehouses usually use dual-motor forks, which increases fork costs. Utility Model Content

[0004] To overcome the drawbacks of wasted space and high cost of dual-motor forks, this utility model provides a double-deep automated warehouse and its fork structure.

[0005] The technical solution of this utility model is as follows: a double-deep automated warehouse, including shelves, non-aisle beams, aisle side beams, pad beams, a first deep cargo unit and a second deep cargo unit. The shelves are provided with multiple non-aisle beams and aisle side beams. Three non-aisle beams and one aisle side beam form a group. The three non-aisle beams are of the same height. The aisle side beams are 150mm lower than the non-aisle beams. Multiple pad beams are provided on the upper side of the aisle side beams. The pad beams are 150mm high. The first deep cargo unit is placed on the pad beams and the adjacent non-aisle beams. The second deep cargo unit is placed on the other two non-aisle beams.

[0006] This utility model also provides a fork structure for a double-depth automated warehouse, including a motor, lower forks, middle forks, upper forks, a bidirectional threaded rod, and a knob. There are two lower forks, one of which is equipped with a motor. The motor drives the two middle forks and the two upper forks through gear transmission. The upper fork includes an upper fork seat and an upper fork arm. The upper fork seat is rotatably provided with a bidirectional threaded rod. The front and rear ends of the bidirectional threaded rod are provided with threads in opposite directions. The two upper fork arms are respectively threaded to the front and rear ends of the bidirectional threaded rod. A knob is provided on the front side of the bidirectional threaded rod. The upper fork arms are slidably connected to the upper fork seat.

[0007] As a preferred technical solution of this utility model, it also includes a slider. Two sliders are provided on the lower side of the upper fork arm, and a sliding groove is provided on the upper side of the upper fork seat. The sliders are slidably connected to the sliding groove. The sliding groove is a dovetail groove, and the shape of the slider is adapted to the sliding groove.

[0008] As a preferred technical solution of this utility model, an anti-slip pad is provided on the upper side of the upper fork arm, and the anti-slip pad is made of rubber.

[0009] As a preferred technical solution of this utility model, it also includes limiting rings, and two limiting rings are provided in the middle of the bidirectional threaded rod.

[0010] As a preferred technical solution of this utility model, the knob has multiple raised lines evenly distributed on its side wall.

[0011] As a preferred technical solution of this utility model, the lowest point of the bidirectional threaded rod and the limiting ring is higher than the upper surface of the upper fork seat.

[0012] Beneficial effects: 1. By designing non-aisle crossbeams, aisle side crossbeams, and pad beams, this utility model makes the height of the first deep cargo unit and the second deep cargo unit the same, reducing the overall height of the rack, thereby increasing the storage space of the warehouse and improving the space utilization rate. At the same time, this design allows the use of single-motor forks, which is cheaper than dual-motor forks, reducing fork costs. In addition, the number of motors is reduced, reducing the risk of equipment damage and maintenance.

[0013] 2. This utility model, through the design of the upper fork seat, upper fork arm and bidirectional threaded rod, allows the distance between the two upper fork arms to be adjusted by rotating the knob, adapting to the handling needs of goods of different sizes, and enhancing the flexibility and adaptability of the equipment.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0021] Example 1: A double-depth automated warehouse, such as... Figure 1 As shown, the structure includes a shelf 1, non-aisle beams 2, aisle side beams 3, pad beams 4, a first deep cargo unit 5, and a second deep cargo unit 6. The shelf 1 is provided with multiple non-aisle beams 2 and aisle side beams 3. The non-aisle beams 2 and aisle side beams 3 are the same size and shape. Three non-aisle beams 2 and one aisle side beam 3 form a group. The three non-aisle beams 2 in the same group are the same height. The aisle side beams 3 are 150mm lower than the non-aisle beams 2. Three pad beams 4 are provided on the upper side of the aisle side beams 3. The pad beams 4 are 150mm high. The first deep cargo unit 5 is placed on the pad beams 4 and the adjacent non-aisle beams 2. The second deep cargo unit 6 is placed on the other two non-aisle beams 2. The first deep cargo unit 5 and the second deep cargo unit 6 are the same height.

[0022] The three non-aisle beams 2 on the same group of shelf 1 are at the same height. The aisle side beam 3 is 150mm lower than the non-aisle beam 2. The pad beam 4 installed on the aisle side beam 3 is 150mm high, so that the first deep cargo unit 5 and the second deep cargo unit 6 above the non-aisle beam 2 and the aisle side beam 3 are at the same height, so as to reduce the height of shelf 1 and increase storage space.

[0023] Example 2: A forklift structure for a double-depth automated warehouse, such as... Figures 2-5 As shown, it includes a motor 7, a lower fork 8, a middle fork 9, an upper fork, a bidirectional threaded rod 12, and a knob 15. There are two lower forks 8, one of which is equipped with a motor 7. The motor 7 drives the two middle forks 9 and the two upper forks through gear transmission. The upper fork includes an upper fork seat 10 and an upper fork arm 11. The upper fork seat 10 is slidably connected to the middle fork 9. A bidirectional threaded rod 12 is rotatably provided between the two upper fork seats 10. The front and rear ends of the bidirectional threaded rod 12 are provided with threads in opposite directions. The two upper fork arms 11 are respectively threaded to the front and rear ends of the bidirectional threaded rod 12. A knob 15 is provided on the front side of the bidirectional threaded rod 12. The upper fork arms 11 are slidably connected to the upper fork seat 10.

[0024] When it is necessary to adjust the distance between the two upper fork arms 11, the double-threaded rod 12 is rotated by rotating the knob 15. Since the threads at both ends of the double-threaded rod 12 are opposite, the rotation of the double-threaded rod 12 will synchronously drive the two upper fork arms 11 to move closer or further apart, thereby changing the distance between the two upper fork arms 11 to meet the specific needs of different working environments.

[0025] like Figure 3 and Figure 4 As shown, it also includes sliders 13. Two sliders 13 are provided on the lower side of the upper fork arm 11, and a slide groove 14 is provided on the upper side of the upper fork seat 10. The sliders 13 and the slide groove 14 are slidably connected. The slide groove 14 is a dovetail groove. The shape of the sliders 13 is adapted to the slide groove 14. When adjusting the distance between the two upper fork arms 11, the sliders 13 and the slide groove 14 ensure that the connection between the upper fork arm 11 and the upper fork seat 10 is more stable, and at the same time prevent the upper fork arm 11 from shifting during the movement.

[0026] An anti-slip pad is provided on the upper side of the upper fork arm 11. The anti-slip pad is made of rubber. The anti-slip pad increases the friction between the upper fork arm 11 and the contact surface of the goods, preventing the goods from slipping during handling and improving the safety of operation.

[0027] like Figure 5 As shown, it also includes limit rings 16. Two limit rings 16 are provided in the middle of the bidirectional threaded rod 12. During the rotation of the bidirectional threaded rod 12, the limit rings 16 are used to limit the excessive movement of the upper fork arm 11 and prevent the upper fork arm 11 from getting too close.

[0028] The knob 15 has multiple raised lines evenly distributed on its side wall, which can increase the friction on the surface of the knob 15, making it easier and more stable for the operator to rotate the knob 15.

[0029] The lowest point of the bidirectional threaded rod 12 and the limiting ring 16 is higher than the upper surface of the upper fork seat 10, ensuring that the bidirectional threaded rod 12 and the limiting ring 16 do not interfere with or collide with the pad beam 4 when handling the second deep cargo unit 6.

[0030] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
