Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically a widened fork carriage. Background Technology

[0002] In recent years, with the rapid development of the logistics industry, forklifts, as core equipment for cargo handling, have seen increasing demands for both usage scenarios and efficiency. In forklift operations, the fork carriage and its mounted forks are key components that directly support and move goods. However, in actual operations, the problem of significant differences in cargo width is frequently encountered. Currently, most forklift carriages are configured to accommodate only a single pair of forks with a fixed fork spacing, typically suitable for goods or pallets with a width of approximately 1000mm. For wider goods (e.g., 2000mm and above) or scenarios requiring the simultaneous handling of two standard pallets, existing fork carriages, due to insufficient width, easily lead to instability of the cargo's center of gravity, posing a risk of tipping over and seriously affecting operational safety and efficiency.

[0003] To address these issues, traditional solutions typically involve replacing the entire fork carriage. However, the fork carriage is usually installed inside the forklift mast, and replacement requires disassembling the mast assembly, which is complex, time-consuming, and necessitates the purchase of multiple sets of fork carriages of different specifications, significantly increasing user costs and warehouse management burden. Furthermore, frequent mast disassembly can affect the stability of the equipment structure and increase the risk of mechanical wear. While some widening devices exist in existing technologies, their structures often rely on complex welding or customized modifications, still exhibiting low disassembly and assembly efficiency and an inability to achieve rapid switchover.

[0004] Therefore, there is an urgent need for a widened fork carriage that is easy to assemble and disassemble, which can quickly expand the fork spacing without replacing the original fork carriage, so as to meet the needs of handling wide goods. Utility Model Content

[0005] The purpose of this utility model is to provide a widened fork carriage to solve the problems mentioned in the background art, so as to quickly expand the fork spacing and realize the purpose of wide cargo handling without replacing the original fork carriage.

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

[0007] A widened fork carriage includes a fork carriage body and forks. A fork bracket is installed between the fork carriage body and the forks. The fork bracket is fixedly connected to the fork carriage body via a connecting assembly. The connecting assembly includes an upper liner and a lower liner. A first upper hook is fixedly connected to the upper liner, and a first lower hook is connected to the lower liner via a fastening device. The fork carriage body is snapped between the first upper hook and the first lower hook.

[0008] As a further embodiment of this utility model: In order for the fork support to be installed on the fork carriage body, the fork support includes a first crossbeam and a second crossbeam arranged opposite each other, a support plate is fixedly connected between the first crossbeam and the second crossbeam, and the forks are installed on the first crossbeam and the second crossbeam.

[0009] As a further embodiment of this utility model: in order to assist in supporting the first crossbeam and the second crossbeam, a fixed side plate is fixedly connected to the same side of the first crossbeam and the second crossbeam respectively.

[0010] As a further embodiment of this utility model: in order for the fork bracket to engage with the fork, a second upper hook is fixedly provided at the upper end of the vertical section of the fork and a second lower hook is fixedly provided at the lower end. The upper end of the cross section of the first crossbeam is a trapezoid that matches the second upper hook, and the lower end of the cross section of the second crossbeam is a trapezoid that matches the second lower hook.

[0011] As a further aspect of this utility model: to prevent the forks from sliding on the first crossbeam, a plurality of grooves are provided at the upper end of the first crossbeam, and the axial direction of the grooves is perpendicular to the length direction of the first crossbeam, so as to prevent the forks from undergoing horizontal displacement on the first crossbeam.

[0012] As a further aspect of this utility model: in order to prevent the connection between the fork support and the fork carriage body from being unstable, at least two of the first upper hook and the first lower hook are provided.

[0013] As a further embodiment of this utility model: in order to enable the first lower hook to be quickly installed and removed from the lower liner, the fastening device is a threaded nut and bolt.

[0014] As a further aspect of this utility model: in order for the fork bracket to be snapped onto the fork carriage body, the distance between the first upper hook and the upper liner plate, and the distance between the first lower hook and the lower liner plate, are all matched with the thickness of the crossbeam of the fork carriage body.

[0015] As a further embodiment of this utility model: in order to handle wide goods, the forks are configured to be at least four for the synchronous handling of wide goods or double pallets.

[0016] As a further embodiment of this utility model: in order for the fork support to be directly installed between the fork carriage body and the forks, the relative distance between the first upper hook and the first lower hook is the same as the relative distance between the second upper hook and the second lower hook, so that the widened fork carriage can be installed between the fork carriage body and the forks.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model features a novel structure. With a fork support length of 2000mm, it can handle wide goods or simultaneously transport two standard pallets. Furthermore, the presence of a first upper hook on the upper liner and a first lower hook on the lower liner via a fastening device allows for quick installation onto the fork carriage body, improving assembly and disassembly efficiency and widening the fork carriage. Since the upper end of the first crossbeam's cross-section is a trapezoid adapted to the second upper hook, and the lower end of the second crossbeam's cross-section is a trapezoid adapted to the second lower hook, the relative distance between the first upper and lower hooks is the same as the relative distance between the second upper and lower hooks. This allows for direct installation between the fork carriage body and the forks without incurring additional costs. Attached Figure Description

[0027] Please see Figure 1-4 In this embodiment of the present invention, a widened fork carriage includes a fork carriage body 4 and forks 3. A fork support 1 is installed between the fork carriage body 4 and the forks 3. The fork support 1 includes a first crossbeam 11 and a second crossbeam 13. The first crossbeam 11 and the second crossbeam 13 are arranged vertically opposite each other. The first crossbeam 11 is located vertically above the second crossbeam 13. A support plate 12 is welded between the first crossbeam 11 and the second crossbeam 13 to support the first crossbeam 11 and the second crossbeam 13. The side end faces of the first crossbeam 11 and the second crossbeam 13 on the same side are respectively fastened to one end of a fixed side plate 14 by bolts to provide auxiliary support for the first crossbeam 11 and the second crossbeam 13.

[0028] The first crossbeam 11 and the second crossbeam 13 are both 2000mm long, longer than the length of the fork carriage body 4, allowing multiple forks 3 to be installed on the fork carriage 1. In this embodiment, four forks 3 are specifically configured for handling wide goods or double pallets. A second upper hook 31 is welded to the upper end of the vertical section of the fork 3 that contacts the fork carriage 1, and a second lower hook 32 is welded to the lower end of the vertical section of the fork 3 that contacts the fork carriage 1. The upper end of the cross section of the first crossbeam 11 is connected to the second upper hook. The hook 31 is adapted to a trapezoidal shape, and the lower end of the cross section of the second crossbeam 13 is a trapezoidal shape adapted to the second lower hook 32, so that the fork 3 can be engaged on the fork support 1. The first crossbeam 11 has multiple grooves 111 evenly spaced at the upper end. The axial direction of the grooves 111 is perpendicular to the length direction of the first crossbeam 11. When the fork 3 is engaged on the fork support 1 and there is a tendency for relative slippage, when it slips to the groove 111, the movement of the fork 3 is restricted by the groove 111, preventing further relative slippage and avoiding handling accidents.

[0029] The fork support 1 is fixedly connected to the fork carriage body 4 via a connecting assembly 2. The connecting assembly 2 includes an upper liner 21 and a lower liner 23. The upper liner 21 is welded to the first crossbeam 11, and a first upper hook 22 is welded to the upper liner 21. A first lower hook 24 is fastened to the lower liner 23 via a fastening device 25. In this embodiment, the fastening device 25 is specifically a threaded nut and bolt. The bolt passes through the nut and the lower liner 23 in sequence, and then is threadedly connected to the first lower hook 24, which has a threaded hole, facilitating the installation and removal of the first lower hook 24. The first upper hook 22 and the first lower hook 24 engage with the fork carriage body 4. The distance between the first upper hook 22 and the upper liner 21, and the distance between the first lower hook 24 and the lower liner 23, are matched with the thickness of the crossbeam of the fork carriage body 4, allowing the fork support 1 to engage with the fork carriage body 4. At least two first upper hooks 22 and two first lower hooks 24 are provided to ensure a stable connection between the fork support 1 and the fork carriage body 4. Figure 4 As shown, after the fork bracket 1 is installed, the four forks 3 can simultaneously transport wide goods.

[0030] The relative distance between the first upper hook 22 and the first lower hook 24 is the same as the relative distance between the second upper hook 31 and the second lower hook 32, so that this widened fork carriage can be installed between the fork carriage body 4 and the fork 3, unifying the installation standard and saving costs.

[0031] This utility model features a novel structure and stable operation. When using this utility model to handle wide goods, such as goods 2000mm wide, that the fork carriage body 4 cannot handle, the forks 3 are removed from the fork carriage body 4. The bolts in the fastening device 25 are unscrewed, and the first lower hook 24 is removed from the lower liner plate 23. The first upper hook 22 is placed on the upper end of the crossbeam of the fork carriage body 4. The lower liner plate 23 is pressed tightly against the fork carriage body 4, and the first lower hook 24 is placed on the lower end of the crossbeam of the fork carriage body 4. After confirming that the first upper hook 22 and the first lower hook 24 are engaged with the fork carriage body 4, the bolts of the fastening device 25 are passed through the nut and the lower liner plate 23 in sequence, and then tightened to the first lower hook 24, ensuring a secure connection between the fork support 1 and the fork carriage body 4. Four forks 3 of the same specification are then attached equidistantly to the fork support 1, and the forks 3 are inserted into the bottom of the wide goods for transport.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0033] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
