Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklifts, specifically a device for quickly switching forks in a functional forklift. Background Technology
[0002] Forklifts play an indispensable role as essential material handling equipment in logistics, warehousing management, and various industrial production sectors. The forks, as a key working component of a forklift, directly affect its handling efficiency and applicability to different goods. In practical applications, the types, shapes, sizes, and handling requirements of goods vary widely. For example, when handling long, narrow goods, longer and stronger forks are needed to ensure stability; while standard-sized forks may be more suitable for handling palletized goods. Furthermore, for some specially shaped or fragile goods, forks with special structures or protective functions may be required. However, traditional forklift forks are usually fixedly installed or replaced through a cumbersome disassembly and replacement process. Fixed forks cannot adapt to diverse goods handling needs, and existing fork replacement methods often require operators to spend a significant amount of time and effort on disassembly and reinstallation. This not only prevents the forklift from operating normally during fork replacement, reducing overall work efficiency, but also may cause damage to the forks or related parts of the forklift due to improper operation during frequent disassembly, increasing equipment maintenance costs. Therefore, we have proposed a functional forklift fork quick switching device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 A forklift fork quick-change device includes a forklift front panel 1, with two sets of forklift lifting platforms 2 fixedly installed on the top of the forklift front panel 1. A tilting roller 3 is provided between the two sets of forklift lifting platforms 2. A fork switching ring 4 is sleeved on the outer wall of the tilting roller 3, and forks A5 and B6 are sleeved on the outer wall of the fork switching ring 4. An installation groove 7 is opened on the top of the forklift front panel 1 corresponding to the two sets of forklift lifting platforms 2. A drive cylinder 8 is fixedly installed in the installation groove 7. A fixing ring 12 for changing forks is sleeved on the outer wall of the tilting roller 3. The device also includes:
[0022] Fork locking assembly, which is installed inside the forklift platform 2, is used to lock the replaced forks.
[0023] Two sets of fork switching rings 4 are provided, both of which are circular. These rings are respectively fitted onto both ends of the tilting roller 3 and located outside the two sets of forklift lifting platforms 2. The angle between fork A5 and fork B6 is 90 degrees. Fork B6 is cylindrical. When the cylindrical fork contacts the goods, the contact surface is curved. Compared to some fork shapes with sharp edges, the cylindrical surface allows the weight of the goods to be distributed more evenly on the fork surface. For example, when handling long, flat, and uniformly textured goods (such as timber or steel pipes), the pressure on each part of the goods is relatively balanced when they contact the cylindrical fork, avoiding excessive local pressure that could lead to deformation or damage to the goods. Just like placing a heavy object on a soft, cylindrical pillow, the pressure of the weight is evenly distributed across the entire surface, rather than concentrated at a single point. Furthermore, cylindrical forks can adapt to various cargo shapes. Different cargoes have different shapes, and cylindrical forks are well-suited to various cargo shapes. For round cargo (such as cylindrical chemical drums or large rollers), cylindrical forks can better conform to the cargo surface, providing stable support. Even if the cargo surface has slight irregularities, cylindrical forks can adapt through minute deformations, ensuring the stability of the cargo during handling. In contrast, square forks have a small contact area when in contact with round goods, making them prone to rolling or slipping. When adjusting the fork angle or turning the goods, cylindrical forks have a smooth surface and relatively low friction. When forklift operators are working in confined spaces and need to frequently turn the forks to adjust the position of the goods, cylindrical forks can be turned more easily, reducing the difficulty and physical exertion of the operator. For example, in warehouse aisle racks where space is limited, operators need to precisely control the fork angle to place the goods in the designated position. The low rotational resistance of cylindrical forks can make the operation smoother.
[0024] Both sets of forklift lifting platforms 2 are provided with lifting grooves 20 that run through both sides of the forklift lifting platform 2. The outer wall of the tilting roller 3 is rotatably fitted with two sets of square sliding blocks 9, and the two sets of sliding blocks 9 are slidably connected in the two sets of lifting grooves 20 respectively.
[0025] The fixed ring 12 is arranged in a circular shape between the two sets of sliding blocks 9.
[0026] Both sets of sliding blocks 9 are fixedly connected to the bottom of a connecting plate 10, and an integrated lifting plate 11 is fixedly connected between the bottoms of the two sets of connecting plates 10.

[0027] The fork locking assembly includes protrusions 13, assembly rods 14, top covers 15, sliding plates 16, and return springs 17. Two sets of protrusions 13 are fixed on the outer wall of the retaining ring 12, with an included angle of 90 degrees between the two sets of protrusions 13. Vertical assembly rods 14 are fixed to the top of each of the two sets of sliding blocks 9. Top covers 15 are fitted on the top of each of the two sets of assembly rods 14. Sliding plates 16 are slidably connected between the two sets of assembly rods 14. Return springs 17 are fitted on the outer walls of the two sets of assembly rods 14 between the sliding plates 16 and the top covers 15.
[0028] The fork locking assembly also includes a cover 18 and a sleeve hole 19. The bottom end of the sliding plate 16 is fixedly connected to the upper part of the fixing ring 12. The bottom of the cover 18 is provided with a sleeve hole 19 that matches the protrusion 13. The cover 18 is slidably sleeved on the protrusion 13 through the sleeve hole 19.
[0029] Partial structural description: Tilting roller 3: It is set between the two sets of forklift lifting platforms 2. Its outer wall is fitted with related components. By rotating, it can drive the forks to switch, realizing the quick replacement of different forks;
[0030] Fork switching ring 4: Two sets are provided, both in the shape of rings, respectively sleeved at both ends of the tilting roller 3 and located outside the two sets of forklift lifting platforms 2. Fork A5 and fork B6 are sleeved on the outer wall of the fork switching ring 4. When the tilting roller 3 rotates, the fork switching ring 4 rotates accordingly, driving the forks to switch.
[0031] Fork A5: Sleeved on the outer wall of the fork switching ring 4, it is a type of fork that can be selected and used according to actual cargo handling needs;
[0032] Fork B6: Also fitted on the outer wall of the fork switching ring 4, forming a certain angle with fork A5, it is another type of fork to meet the handling requirements of different goods;
[0033] Sliding block 9: Square in shape, rotatably sleeved on the outer wall of the tilting roller 3, and slidably connected to the lifting slots 20 opened on the two sets of forklift lifting platforms 2. The sliding block 9 slides up and down within the lifting slots 20 to realize the lifting movement of the forks;
[0034] Connecting plate 10: The bottom of each of the two sets of sliding blocks 9 is fixedly connected to a connecting plate 10, and an integrated lifting plate 11 is fixedly connected between the bottoms of the two sets of connecting plates 10, so as to transmit the up and down movement of the sliding blocks 9 to the lifting plate 11 and realize the lifting of the entire fork.
[0035] Lifting plate 11: It is fixedly connected to the piston rod of the drive cylinder 8 and moves up and down under the action of the drive cylinder 8, driving the connecting plate 10 and the sliding block 9 to move synchronously, thereby realizing the lifting of the forks;
[0036] Fixed ring 12: It is arranged in a circular shape between the two sets of sliding blocks 9 and is sleeved on the outer wall of the flipping roller 3. It is used for fixing and positioning when changing the forks. At the same time, the outer wall is fixed with a protrusion 13, which cooperates with the fork locking assembly to lock the forks.
[0037] Protrusion 13: Two sets, fixed on the outer wall of the retaining ring 12, with an included angle of 90 degrees between the two sets of protrusions 13, which are adapted to the sleeve hole 19 at the bottom of the sleeve cover 18 and are used for locking and unlocking the fork locking assembly.
[0038] Top cover 15: Two sets, respectively fitted on the top of the two sets of component rods 14, to seal and protect the top of the component rods 14;
[0039] Sliding plate 16: It is slidably sleeved between the two sets of component rods 14, and the locking and unlocking operations of the fork locking component are realized by sliding up and down;
[0040] Reset spring 17: Two sets, sleeved on the outer wall of the two sets of component rods 14 between the corresponding sliding plate 16 and the top cover 15, to provide the sliding plate 16 with a restoring force so that it can automatically reset after unlocking;
[0041] Cover 18: It is fixed to the bottom of the sliding plate 16 above the fixing ring 12. The bottom is provided with a sleeve hole 19 that matches the protrusion 13. It slides on the protrusion 13 through the sleeve hole 19 to lock the forks.
[0042] Hole 19: Located at the bottom of cover 18, it is adapted to protrusion 13 and is used for connection and locking of cover 18 and protrusion 13.
[0043] Working principle: When goods need to be handled, the drive cylinder 8 is started, and the piston rod on the drive cylinder 8 pushes the lifting plate 11 upward, causing the two sets of connecting plates 10 to push the two sets of sliding blocks 9 upward respectively. The two sets of sliding blocks 9 slide upward in the lifting grooves 20 on the two sets of forklift lifting platforms 2. At the same time, the two sets of forks A5 on the two sets of fork switching rings 4 lift the goods. When the forks need to be replaced, the two sets of sliding blocks 9 are slid back to their original positions in the lifting grooves 20, and the sliding plate 16 is pulled upward between the two sets of component rods 14. The return spring 17 slides upward with the sliding plate 16. After being squeezed, the fork deforms and shortens. The cover 18 disengages from one of the protrusions 13 through the sleeve hole 19. Then, the tilting roller 3 rotates 90 degrees on the two sets of sliding blocks 9. The fork switching ring 4 drives the fork B6 from a vertical position to a horizontal position as the tilting roller 3 rotates. The other set of protrusions 13 is located directly below the sleeve hole 19 after the fixing ring 12 rotates 90 degrees. The sliding plate 16 is relaxed, and the sliding plate 16 is pushed downward by the rebound force of the two sets of return springs 17, so that the cover 18 covers the other set of protrusions 13 through the sleeve hole 19, preventing the two sets of forks B6 from overturning when handling goods.
