Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift technology, and in particular to a fork structure for railway freight forklifts used for efficient loading and unloading operations. Background Technology
[0002] Railway freight is one of the important modes of cargo transportation. Its transport volume and efficiency play a vital role in ensuring the stability and efficiency of the logistics supply chain. Forklifts are usually used for loading and unloading goods.
[0003] Currently used forklifts typically have fixed-width forks that cannot be adjusted or extended during use. When handling large and lightweight goods, the contact area between the forks and the goods is small, resulting in poor stability of the goods during loading and unloading and a tendency for the goods to tip over. Furthermore, when loading and unloading bagged goods, it is necessary to use the forks to lift and transport them. However, since the fork surfaces are smooth, bagged goods can easily slip off. Summary of the Invention
[0004] This utility model provides a fork structure for railway freight forklifts for efficient loading and unloading operations. It has a larger contact area when loading and unloading large and light-weight goods, making it less likely for the goods to tip over. The lifting straps of bagged goods will not slip during the loading and unloading process, effectively preventing the goods from slipping.
[0005] In a first aspect, this utility model provides a fork structure for a railway freight forklift used in efficient loading and unloading operations, specifically including: a fork carriage;
[0006] Two forks are symmetrically mounted on the left side of the fork carriage; four sets of eight side support plates are welded to the front and rear outer walls of the forks; two sets of four adjustment plates are also slidably mounted on the forks; and an extension fork plate is also installed on the top of the forks.
[0007] When the adjusting plate is rotated to a vertical position and slid down to the bottom, the top surface of the adjusting plate will be on the same plane as the bottom inner wall of the rectangular groove at the top of the fork.
[0008] The forks are provided with two rectangular grooves that extend from front to back, and the width and thickness of the rectangular grooves are equal to the length and thickness of the adjustment plate, respectively.
[0009] The width of the extended fork plate is twice the width of the fork. The bottom of the extended fork plate is provided with a long strip groove with a width corresponding to the width of the fork. The long strip groove at the bottom of the extended fork plate is also provided with four outward protruding notches. The extended fork plate is installed on the rear support plate at the top of the fork and is embedded in the notches at the bottom of the extended fork plate and is in close contact with the inner wall of the notches.
[0010] The adjusting plates are arranged in pairs and are of equal size. The width of the adjusting plate is half the width of the fork. A round rod is also provided on both the left and right sides of the adjusting plate.
[0011] Each of the adjustment plates has a magnet inside, and the magnets inside two adjacent adjustment plates attract each other. The extension fork plate is made of iron.
[0012] The side support plates are respectively set on the front and rear, left and right sides of the rectangular groove at the top of the fork, and four L-shaped grooves are also provided on both sides of the rectangular groove at the top of the fork and on the side support plates. The round rods on the left and right sides of the adjustment plate can slide in the L-shaped grooves.
[0013] This utility model provides a fork structure for railway freight forklifts used in efficient loading and unloading operations, which has the following beneficial effects:
[0014] The extended fork plate in this invention can be stably installed on the top of the forks. Moreover, the width of the extended fork plate is relatively wide, which provides a larger contact area when loading and unloading large and light goods, making it less likely for the goods to tip over and improving the stability of loading and unloading. When loading and unloading bagged goods, the straps of the bagged goods can be locked in the rectangular grooves on the top of the forks, preventing the straps of the bagged goods from slipping during the loading and unloading process, effectively preventing the goods from slipping off.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] This utility model proposes a fork structure for a railway freight forklift used for efficient loading and unloading operations, including: a fork carriage 1;
[0029] Two forks 2 are symmetrically mounted on the left side of the fork carriage 1. The fork carriage 1 supports the forks, and the forks 2 are used for loading and unloading goods. Four sets of eight side support plates 3 are welded to the front and rear outer walls of the forks 2. The side support plates 3 provide support and guidance when the adjustment plates 4 are adjusted. Two sets of four adjustment plates 4 are also slidably mounted on the forks 2. When folded, the adjustment plates 4 can be hidden in the rectangular grooves at the top of the forks 2, thus keeping the top surface of the forks 2 flat and ensuring normal loading and unloading of goods. When the adjustment plates 4 are adjusted outwards, they are located on the front and rear sides of the forks 2 without obstructing the rectangular grooves at the top of the forks 2. Then, the slings of bagged goods can be secured in the rectangular grooves at the top of the forks 2. During loading and unloading, the straps of bagged goods will not slip, preventing the goods from falling. The top of the fork 2 is also equipped with an extension fork plate 5. When loading and unloading large and light goods, the extension fork plate 5 can be installed on the top of the fork 2. When the extension fork plate 5 is installed, the fork 2 will be embedded in the long groove at the bottom of the extension fork plate 5, and the side support plate 3 will be embedded in the notch at the bottom of the extension fork plate 5. This restricts the horizontal movement of the extension fork plate 5. Then, large and light goods can be loaded and unloaded through the extension fork plate 5 on the top of the fork 2. During loading and unloading, the extension fork plate 5 has a larger contact area with large and light goods, making it less likely for the goods to tip over.
[0030] In this embodiment, as Figure 4As shown, when the adjusting plate 4 is rotated to the vertical position and slid down to the bottom, the top surface of the adjusting plate 4 will be on the same plane as the bottom inner wall of the rectangular groove at the top of the fork 2. After adjusting the adjusting plate 4 outward, it will be located on the front and rear sides of the fork 2 and will not block the rectangular groove at the top of the fork 2. Then, the straps of the bagged goods can be caught in the rectangular groove at the top of the fork 2 for loading and unloading. During the loading and unloading process, the straps of the bagged goods will not slip, thus preventing the goods from falling.
[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the top of the fork 2 is provided with two rectangular grooves that run from front to back. The width and thickness of the rectangular grooves are equal to the length and thickness of the adjusting plate 4, respectively. When it is necessary to load and unload small and heavy goods, the adjusting plate 4 can be folded into the rectangular grooves on the top of the fork 2. After the adjusting plate 4 is folded, it will be hidden in the rectangular grooves on the top of the fork 2, and then the goods can be loaded and unloaded through the fork 2.
[0032] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the width of the extension fork plate 5 is twice the width of the fork 2. The bottom of the extension fork plate 5 has a long, narrow groove with a width corresponding to the width of the fork 2. The long, narrow groove at the bottom of the extension fork plate 5 also has four outwardly protruding notches. When the extension fork plate 5 is installed on top of the fork 2, the side support plate 3 is embedded in the notch at the bottom of the extension fork plate 5 and fits tightly against the inner wall of the notch. When loading or unloading large and lightweight goods, the extension fork plate 5 can be installed on top of the fork 2. When the extension fork plate 5 is installed, the fork 2 is embedded in the long, narrow groove at the bottom of the extension fork plate 5, and the side support plate 3 is embedded in the notch at the bottom of the extension fork plate 5. This restricts the horizontal movement of the extension fork plate 5, allowing for loading and unloading of large and lightweight goods via the extension fork plate 5 on top of the fork 2. During loading and unloading, the extension fork plate 5 has a larger contact area with the large and lightweight goods, reducing the likelihood of goods tipping over.
[0033] In this embodiment, as Figure 1 and Figure 4 As shown, the adjustment plates 4 are arranged in pairs and are of equal size. The width of the adjustment plate 4 is half the width of the fork 2. A round rod is provided on both the left and right sides of the adjustment plate 4. Therefore, when the adjustment plate 4 is folded up, it will be hidden in the rectangular groove at the top of the fork 2 to ensure the overall strength of the fork 2. When the adjustment plate 4 is pushed and adjusted, the round rods on the left and right sides will slide in the rectangular groove at the top of the fork 2 and the L-shaped groove on the side support plate 3, thereby ensuring the stability of the adjustment plate 4 during adjustment.
[0034] In this embodiment, as Figure 1 , Figure 4 and Figure 6 As shown, the side support plates 3 are respectively set on the front and rear left and right sides of the rectangular groove at the top of the fork 2, and four L-shaped grooves are also provided on both sides of the rectangular groove at the top of the fork 2 and on the side support plates 3. The round rods on the left and right sides of the adjustment plate 4 can slide in the L-shaped grooves. When the adjustment plate 4 is pushed and adjusted, the round rods on the left and right sides will slide in the rectangular groove at the top of the fork 2 and on the L-shaped grooves on the side support plates 3, thereby ensuring the stability of the adjustment plate 4 during adjustment.
[0035] Example 2, based on Example 1, such as Figures 1-6 As shown, each of the adjustment plates 4 has a magnet inside, and the magnets inside two adjacent adjustment plates 4 attract each other. The extension fork plate 5 is made of iron. When it is necessary to load and unload small and heavy goods, the adjustment plate 4 can be folded into the rectangular groove at the top of the fork 2. After the adjustment plate 4 is folded, it will be tightly attracted together by the magnet inside, so that the two adjustment plates 4 can be locked in the rectangular groove at the top of the fork 2. Then the goods can be loaded and unloaded by the fork 2. Moreover, after the extension fork plate 5 is installed, the magnet inside the adjustment plate 4 will play an auxiliary attraction role to prevent the extension fork plate 5 from falling off.
[0036] The working principle of this embodiment is as follows: During installation, the fork carriage 1 can be fixed to the forklift. When loading and unloading small and heavy goods, the adjusting plate 4 can be folded into the rectangular groove at the top of the fork 2. After folding, the adjusting plate 4 will be tightly attracted together by the magnet inside, thereby locking the two adjusting plates 4 in the rectangular groove at the top of the fork 2. Then, the goods can be loaded and unloaded through the fork 2. When loading and unloading large and light goods, the extension fork plate 5 can be installed on the top of the fork 2. When the extension fork plate 5 is installed, the fork 2 will be embedded in the elongated groove at the bottom of the extension fork plate 5, and the side support plate 3 will be embedded in the notch at the bottom of the extension fork plate 5. This restricts the horizontal movement of the extension fork plate 5, and then the large and light goods can be loaded and unloaded through the extension fork plate 5 at the top of the fork 2. For loading and unloading lighter goods, the extended fork plate 5 has a larger contact area with larger but lighter goods, making it less likely for the goods to tip over. When loading and unloading bagged goods, the adjusting plate 4 can be pushed towards the front and rear sides respectively, then rotated to a vertical position and pushed down to the bottom. During this process, the round rods on the left and right sides of the adjusting plate 4 will slide in the rectangular groove on the top of the fork 2 and the L-shaped groove on the side support plate 3, thus ensuring the stability of the adjusting plate 4 during adjustment. Finally, the adjusting plate 4 will be located on the front and rear sides of the fork 2 without obstructing the rectangular groove on the top of the fork 2. Then, the sling of the bagged goods can be caught in the rectangular groove on the top of the fork 2 for loading and unloading. During the loading and unloading process, the sling of the bagged goods will not slip, preventing the goods from falling.
