[0002] A bi-directional forklift is a material transfer mechanism with bi-directional telescopic function, widely used in modern logistics and intelligent warehousing systems. It can automatically extend and retract to achieve precise positioning and handling of goods in different locations, and has a strong load capacity.

[0003] In actual use, the size of the upper fork body cannot be changed. Some goods are large in size. When handling them, because the relative contact area between the goods and the upper fork body is small, if shaking occurs during transportation, large goods are easy to fall off the upper fork body, causing damage to the goods and affecting transportation.

[0004] At the same time, the area of ​​the upper fork body cannot be adjusted according to the shelf or handling space, which affects handling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a conveniently adjustable bidirectional fork to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] The present invention provides the following preferred embodiments:

[0032] Example 1, as Figures 1-10 As shown, a conveniently adjustable bidirectional fork includes a lower fork body 1, a middle fork body 2, and an upper fork body 3, and also includes a telescopic mechanism and an adjustment mechanism. The middle fork body 2 is located above the lower fork body 1, and the upper fork body 3 is located above the middle fork body 2.

[0033] The telescopic mechanism includes a gear 4, a pushing component and a moving component. The gear 4 is rotatably mounted on the middle fork body 2, the pushing component is mounted on one side of the lower fork body 1, and the moving component is mounted between the lower fork body 1 and the upper fork body 3.

[0034] The adjustment mechanism includes two extension plates 7 and an extension assembly. The two extension plates 7 are slidably disposed on the top of the upper fork body 3, and the extension assembly is disposed between the upper fork body 3 and the two extension plates 7.

[0035] like Figures 1-10 As shown, the pushing assembly includes a first cylinder 8, a connecting rod 9, a pushing plate 10, a slide groove 11, a horizontal plate 12, two clearance grooves 13, and two vertical plates 14. The first cylinder 8 is fixedly installed on one side of the lower fork body 1. The slide groove 11 is opened on one side of the lower fork body 1. The horizontal plate 12 is fixedly installed inside the lower fork body 1. The two clearance grooves 13 are both opened on the top of the horizontal plate 12. The two vertical plates 14 are both fixedly installed below the middle fork body 2, and each vertical plate 14 passes through a clearance groove 13 and is fixedly connected to the top of the pushing plate 10. The pushing plate 10 is fixedly installed between the two vertical plates 14. One end of the connecting rod 9 is fixedly connected to the output end of the first cylinder 8. The end of the connecting rod 9 away from the first cylinder 8 passes through the slide groove 11 and is fixedly connected to one side of the pushing plate 10. Specifically, a fixing rod is fixed to the end of the connecting rod 9 away from the first cylinder 8, and the other end of the fixing rod is fixedly connected to the pushing plate 10. That is, the connecting rod 9 can be connected to the pushing plate 10 through the fixing rod.

[0036] When goods need to be moved, the controller controls the extension and retraction of the first cylinder 8, which drives the connecting rod 9 to move. The connecting rod 9 drives the push plate 10 and the two vertical plates 14 to move, which in turn drives the middle fork body 2 to move. When the middle fork body 2 moves, it drives the upper fork body 3 to move through the moving component, thus realizing the movement of the fork body. After the goods are picked up, the first cylinder 8 retracts, which drives the middle fork body 2 and the upper fork body 3 to move in opposite directions to move the goods.

[0037] like Figures 1-10 As shown, guide grooves 15 are provided on both sides of the middle fork body 2, and guide strips 16 that slide in coordination with the guide grooves 15 are provided on both sides of the lower fork body 1.

[0038] Guide bars 16 are provided on both sides of the lower fork 1 and are slidably disposed within guide grooves 15 provided on both sides of the middle fork 2, thereby reducing the resistance of the middle fork 2 sliding on the lower fork 1.

[0039] like Figures 1-10 As shown, the moving component includes a rotating groove 17, an upper rack 5, and a lower rack 6. The lower rack 6 is fixedly mounted above the horizontal plate 12, and the upper rack 5 is fixedly mounted below the upper fork 3. The rotating groove 17 is opened in the middle of the middle fork 2, and the gear 4 is rotatably mounted between the rotating grooves 17. The upper rack 5, the gear 4, and the lower rack 6 mesh in sequence. It should be noted that the gear 4 is located in the middle of the middle fork 2, so that the upper fork 3 and the middle fork 2 can slide in both directions.

[0040] When the fork body 2 moves, it will drive the gear 4 to move together. Since the upper rack 5, gear 4 and lower rack 6 mesh in sequence, as gear 4 moves, it will rotate under the limit of lower rack 6. When gear 4 rotates, it will drive the upper rack 5 to move at the same time, so as to realize the unfolding of the fork.

[0041] like Figures 1-10 As shown, support frames 18 are provided on both sides of the lower fork 1, and a guide rail 19 is fixedly provided on the top of each support frame 18. Multiple rollers 20 are rotatably provided on both sides of the upper fork 3, and the multiple rollers 20 are slidably provided in the two guide rails 19. The rollers 20 are slidably provided in the two guide rails 19 to reduce the resistance of the upper fork 3 sliding.

[0042] like Figures 1-10 As shown, the extension assembly includes a second cylinder 21, a placement groove 22, a top plate 23, a slider 24, a groove 25, and two wedge blocks 26. The placement groove 22 is opened on the top of the upper fork 3. The second cylinder 21 is fixedly installed inside the placement groove 22. The top plate 23 is fixedly connected to the output end of the second cylinder 21. The slider 24 is fixedly installed below the top plate 23. The groove 25 is opened on the top of the upper fork 3. The slider 24 is slidably installed in the groove 25. Each wedge block 26 is fixedly installed on the side of an extension plate 7 near the top plate 23.

[0043] During forklift operation, situations may arise where shelves are densely packed or the entry point is too small, preventing the forks from reaching under the goods. Additionally, situations may occur where the goods are large and the upper fork body 3 is small. During handling, due to the large size of the goods, vibrations during transport can cause them to fall off the upper fork body 3, damaging them and affecting transport. In such cases, the controller extends and retracts the second cylinder 21, moving the top plate 23 forward. As the top plate 23 moves forward, it presses against the two wedge blocks 26. Since the extension plate 7 is slidably positioned on top of the upper fork body 3, the pressure from the top plate 23 causes the two wedge blocks 26 to move to the sides, moving the two extension plates 7 away from the upper fork body 3 and expanding the upper fork body 3. This changes the contact area between the extension plates 7 and the goods, increasing stability during transport.

[0044] like Figures 1-10 As shown, the bottom surfaces of the two extension plates 7 are provided with slide bars 27, and the top of the upper fork body 3 is provided with a sliding groove 28 corresponding to the slide bars 27. The expansion of the two extension plates 7 is guided by the sliding of the slide bars 27 and the sliding groove 28.
