Description

Technical Field

[0001] This application relates to the field of forklifts, and in particular to a high-stability AGV forklift. Background Art

[0002] An AGV forklift is an automatic guided forklift used for loading and unloading goods.

[0003] In related technologies, an AGV forklift includes a forklift body and a fork. The fork is connected to the forklift body and is used to lift the goods.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when the fork suddenly stops, the goods are likely to slide off the fork under the action of inertia. When the goods move to a relatively far position on the fork, it is easy to cause the rear end of the forklift to tilt up, which is likely to cause the forklift to be unstable. Utility Model Content

[0005] In order to improve the stability of the forklift, this application provides a high-stability AGV forklift.

[0006] The high-stability AGV forklift provided by this application adopts the following technical solutions:

[0007] A high-stability AGV forklift includes a forklift body, a fork, and a blocking assembly. The fork is slidably connected to the forklift body in the vertical direction. The blocking assembly includes a rotating rod and a blocking portion. The rotating rod is rotatably connected to the fork. One end of the rotating rod is connected to the blocking portion, and the other end of the rotating rod is closer to the forklift body than the blocking portion. The fork has a supporting surface for supporting the goods. At least a part of the blocking portion is located above the supporting surface. The forklift includes a maintaining member for maintaining at least a part of the blocking portion above the supporting surface.

[0008] By adopting the above technical solutions, when suddenly stopping, the goods will move in the direction away from the forklift body.

Detailed implementation manners

[0014] The following further elaborates on this application Figures 1-4 with reference to the attached drawings.

[0015] An embodiment of this application discloses a highly stable AGV forklift. Referring to Figure 1 , Figure 2 and Figure 3 , a highly stable AGV includes a forklift body 1, a fork 2, and a blocking assembly 3. The fork 2 is slidably connected to the forklift body 1 in the vertical direction. The blocking assembly 3 includes a rotating rod 31 and a blocking portion 32. The rotating rod 31 is rotatably connected to the fork 2. One end of the rotating rod 31 is connected to the blocking portion 32, and the other end of the rotating rod 31 is closer to the forklift body 1 than the blocking portion 32. The fork 2 has a supporting surface 21 for supporting goods. At least a part of the blocking portion 32 is located above the supporting surface 21. The forklift includes a maintaining member for maintaining at least a part of the blocking portion 32 above the supporting surface 21 and a driving member for driving the blocking portion 32 to rotate below the supporting surface 21.

[0016] When the fork 2 drives the goods to move upward, the maintaining member maintains the state of the blocking portion 32 being located above the supporting surface 21.

[0017] When the goods are located on the supporting surface 21 and between the forklift body 1 and the blocking portion 32, during an emergency stop, the goods will move in a direction away from the forklift body 1. Since at least a part of the blocking portion 32 is located above the supporting surface 21 and the maintaining member is used to maintain at least a part of the blocking portion 32 above the supporting surface 21, the goods will slide to the blocking portion 32, and the blocking portion 32 will block the goods, improving the stability of the forklift.

[0018] When unloading, the driving member drives the blocking portion 32 to rotate so that the blocking portion 32 is located below the supporting surface 21, facilitating the sliding of the goods off the supporting surface 21.

[0019] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3, the rotating rod 31 is located below the support surface 21, and the maintaining member is located below the support surface 21. This can reduce the influence of the rotating rod 31 and the maintaining member on the goods, enabling the goods to be more conveniently moved onto the support surface 21.

[0020] In some embodiments, referring to Figure 3 and Figure 4 , the maintaining member includes a maintaining block 33. The maintaining block 33 is connected to the other end of the rotating rod 31. The maintaining block 33 is closer to the forklift body 1 than the blocking portion 32. Along the horizontal direction, the distance between the blocking portion 32 and the rotation axis of the rotating rod 31 is defined as L1. Along the horizontal direction, the distance between the maintaining block 33 and the rotation axis of the rotating rod 31 is defined as L2. The weight of the blocking portion 32 is G1, and the weight of the maintaining block 33 is G2, where L1×G1 < L2×G2; the maintaining block 33 is located below the support surface 21. The maintaining block 33 is located below the support surface 21.

[0021] During use, since L1×G1 < L2×G2, it can enable the maintaining block 33 to maintain below the support surface 21 and maintain at least part of the blocking portion 32 above the support surface 21, with a simple structure and low cost.

[0022] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the blocking portion 32 includes a blocking plate 321, a reinforcing plate 322, and a reinforcing rib 323. Both the reinforcing rib 323 and the reinforcing plate 322 are connected to the blocking plate 321. The blocking plate 321 is fixedly connected to one end of the rotating rod 31. The blocking plate 321 is at least partially located above the support surface 21. Both the reinforcing rib 323 and the reinforcing plate 322 are located on the side of the blocking plate 321 facing away from the maintaining block 33. The reinforcing plate 322 is perpendicularly arranged with the blocking plate 321. The reinforcing rib 323 is located between the reinforcing plate 322 and the blocking plate 321. The reinforcing rib 323 is connected to the reinforcing plate 322, and the reinforcing rib 323 is connected to the blocking plate 321.

[0023] The reinforcing rib 323 and the reinforcing plate 322 can strengthen the blocking plate 321. During an emergency stop, since both the reinforcing rib 323 and the reinforcing plate 322 are located on the side of the blocking plate 321 facing away from the maintaining block 33, the reinforcing plate 322 is perpendicularly arranged with the blocking plate 321, the reinforcing rib 323 is located between the reinforcing plate 322 and the blocking plate 321, the reinforcing rib 323 is connected to the reinforcing plate 322, and the reinforcing rib 323 is connected to the blocking plate 321, the blocking plate 321 is not easily damaged by the goods.

[0024] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3The reinforcing rib 323 has an inclined surface 324 , which is inclined and used to contact the cargo. The highest point of the inclined surface 324 is closer to the blocking plate 321 than the lowest point of the inclined surface 324 .

[0025] When the fork 2 passes under the cargo, the inclined surface 324 contacts the cargo and drives the blocking plate 321 to rotate downward, and the fixed rod contacts the blocking portion 32, and further the fixed rod contacts the reinforcing plate 322. When the fixed rod contacts the reinforcing plate 322, the highest point of the inclined surface 324 is in contact with or adjacent to the supporting surface 21, which facilitates the cargo to slide onto the supporting surface 21. The reinforcing ribs 323 have the function of guiding the cargo, and the reinforcing ribs 323 have a reinforcing effect on the blocking plate 321, and the structure is simple.

[0026] In some embodiments, reference Figure 1 , Figure 2 as well as Figure 3 The driving member includes a fixing plate 4, which is located below the maintaining block 33 and is used to contact the maintaining block 33. When unloading is required, the fork 2 moves downward so that the maintaining block 33 contacts the fixing plate 4, driving the maintaining block 33 and the rotating rod 31 to rotate, so that the blocking portion 32 rotates, so that the blocking portion 32 is located below the supporting surface 21, which is convenient for unloading of goods.

[0027] Reference Figure 1 , Figure 2 as well as Figure 3 The forklift includes a maintaining rod 6, which is located below the maintaining block 33. The maintaining rod 6 is fixedly connected to the fork 2, and the maintaining rod 6 is used to contact the rotating rod 31, maintaining the blocking plate 321 at least partially located on the supporting surface 21 and the rotating rod 31 is always located below the supporting surface 21. In the horizontal direction, the maintaining rod 6 is located on one side of the fixed plate 4.

[0028] In some embodiments, reference Figure 1 , Figure 2 as well as Figure 3 The forklift includes a telescopic rod 5 and a locking member. The telescopic rod 5 is slidably connected to the rotating rod 31 along the direction from the blocking plate 321 to the rotating axis of the rotating rod 31. The locking member is used to lock the telescopic rod 5 to the rotating rod 31. The telescopic rod 5 is connected to the blocking plate 321. The locking member includes a locking bolt 51. The locking bolt 51 is threadedly connected to the rotating rod 31. The tail of the locking bolt 51 abuts against the telescopic rod 5. When in use, the operator can adjust the length of the telescopic rod 5 to achieve blocking of goods of different lengths, thereby improving applicability.

[0029] The high-stability AGV forklift of the present application has the following principle. In the normal state, the maintaining block 33 is in contact with the fixing plate 4, and the maintaining blocking portion 32 is located below the supporting surface 21, and the inclined surface 324 is in contact with the supporting surface 21, which is convenient for guiding the goods onto the supporting surface 21. After the goods move onto the supporting surface 21, the forklift forks 2 move vertically upward. Under the action of the gravity of the maintaining block 33, the rotating rod 31 rotates, and the blocking portion 32 rises, so that at least part of the blocking plate 321 is located above the supporting surface 21 and is maintained. In case of an emergency stop, the goods move in the direction close to the blocking plate 321, and the blocking plate 321 is used to block the goods to maintain the balance of the forklift and improve the stability of the forklift.

[0030] During unloading, the forklift forks 2 descend, so that the maintaining block 33 is in contact with the fixing plate 4, driving the rotating rod 31 and the blocking portion 32 to rotate, so that the blocking portion 32 is located below the supporting surface 21, which is convenient for unloading.

[0031] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
