[0047] To ensure the stability of goods transported by forklifts, load stabilizing devices are usually installed near the forks.

Current load stabilizing devices are difficult to adapt to goods of different sizes, resulting in poor stability for larger goods.
[0048] In view of this, the present invention provides a forklift device with a load-stabilizing structure, including a fork carriage, a fork seat, forks, and a stabilizing mechanism.

[0050] You can refer to this. Figures 1 to 5This utility model provides a forklift device 100 with a load-stabilizing structure, including a fork carriage 110, a fork seat 120, forks 130, and a stabilizing mechanism 140. The fork carriage 110 is configured to be connected to the front end of a forklift 200. The fork seat 120 is movably disposed on the fork carriage 110 along the length direction of the fork carriage 110. The forks 130 are mounted on the fork seat 120 and are used for forking and transporting goods. The length direction of the fork carriage 110 is consistent with the width direction of the forklift 200. The stabilizing mechanism 140 includes a pressure plate 141 and a hook 142. The first end of the pressure plate 141 is movably disposed on the fork seat 120 along the vertical direction to press the goods on the forks 130 from above. The hook 142 is movably disposed on the second end of the pressure plate 141 along the length direction of the pressure plate 141 to hook the goods on the forks 130.
[0051] The forklift device 100 with load stabilization structure provided in this embodiment of the utility model allows goods to be carried on the forks 130 when transporting goods. By adjusting the position and height of the pressure plate 141 on the fork seat 120, the pressure plate 141 can be pressed against the top of the goods to initially stabilize them. At the same time, the extension distance of the hook 142 along the pressure plate 141 can be adjusted so that the hook 142 can be hooked tightly to the front edge of the goods when facing goods of different volumes, preventing the goods from tipping forward and greatly improving the stability of the goods.
[0052] In the above embodiments, the stabilizing mechanism 140 may further include a slide 143 and a first hydraulic cylinder 144. The fork seat 120 has a first guide rail, and the slide 143 is slidably disposed on the first guide rail in a vertical direction. The first end of the pressure plate 141 is connected to the slide 143. The first end of the first hydraulic cylinder 144 is connected to the bottom end of the slide 143, and the second end of the first hydraulic cylinder 144 is connected to the fork seat 120. The first hydraulic cylinder 144 is used to drive the slide 143 to slide up and down along the first guide rail. The slide 143's sliding arrangement along the first guide rail of the fork seat 120 provides precise guidance for the movement of the pressure plate 141, ensuring stable and smooth lifting and lowering without swaying or jamming. The first hydraulic cylinder 144, as a driving component, can output stable thrust and pull, precisely driving the slide 143 to slide up and down along the first guide rail, enabling the pressure plate 141 to accurately reach the required height, avoiding errors from manual adjustment, and improving the accuracy and timeliness of the pressure plate 141's height adjustment. When goods need to be transported by forklift, the slide 143 can work in conjunction with the first hydraulic cylinder 144. Specifically, when the forks 130 are inserted into the bottom of the goods, the first hydraulic cylinder 144 can immediately drive the slide 143 to raise the pressure plate 141. The pressure plate 141 can press the goods down the moment they are lifted by the forklift. The whole process is quick and smooth, which can avoid the problem of goods shaking or shifting when starting, turning or passing through bumpy roads due to the untimely adjustment of the height of the pressure plate 141. This lays a solid foundation for the stability of subsequent transportation, ensures that the forklift 200 handling operation is efficient and reliable, and makes the logistics handling process smoother.
[0053] In the above embodiments, the stabilizing mechanism 140 may further include a second hydraulic cylinder 145. The first end of the pressure plate 141 and the first end of the second hydraulic cylinder 145 are both hinged to the slide block 143, and the second end of the second hydraulic cylinder 145 is hinged to the pressure plate 141. The second hydraulic cylinder 145 is used to drive the pressure plate 141 to rotate. The second hydraulic cylinder 145 can drive the second end of the pressure plate 141 to rotate around its first end. With this design, when dealing with goods that do not require stabilization by the stabilizing mechanism 140 (e.g., on a flat surface where the forklift 200 does not need to make sharp turns), the second hydraulic cylinder 145 can drive the second end of the pressure plate 141 to rotate to another position to avoid interfering with the forklift transport, thereby improving the efficiency of forklift transport. Furthermore, designing the pressure plate 141 as a rotatable structure also allows it to adapt to goods of different shapes. For example, if the top of the goods has a certain slope, rotation can cause the pressure plate 141 to rotate to the same angle as the top of the goods, thus pressing it more smoothly against the top of the goods.
[0054] In the above embodiments, the hinge point of the second hydraulic cylinder 145 on the slide 143 can be located above the hinge point of the pressure plate 141 on the slide 143. This design ensures that the pressure plate 141 can rotate to a vertical position, which not only avoids the forklift from transporting goods to the greatest extent, but also extends the overall height of the forklift device 100 by the upright pressure plate 141, so that the forklift device 100 can adapt to the forklift transport of goods at higher heights.
[0055] In the above embodiments, the stabilizing mechanism 140 may further include a third hydraulic cylinder 146. The second end of the pressure plate 141 has a second guide rail, and the hook 142 is slidably mounted on the second guide rail. The first end of the third hydraulic cylinder 146 is connected to the pressure plate 141, and the second end of the third hydraulic cylinder 146 is connected to the hook 142. The third hydraulic cylinder 146 is used to drive the hook 142 to slide along the second guide rail. It can be understood that when dealing with large-volume goods, the third hydraulic cylinder 146 can stably and precisely drive the hook 142 to slide flexibly along the second guide rail, allowing the hook 142 to quickly adjust its extension length and position according to the specific position of the front edge of the goods, accurately hooking the goods. Furthermore, the third hydraulic cylinder 146 can also work in conjunction with the first hydraulic cylinder 144 and the second hydraulic cylinder 145 to improve operational efficiency.
[0056] In the above embodiments, a fourth hydraulic cylinder 150 may also be included. The fork carriage 110 has a third guide rail 111 extending along its length. The first end of the fourth hydraulic cylinder 150 is connected to the fork carriage 110, and the second end of the fourth hydraulic cylinder 150 is connected to the fork seat 120. The fourth hydraulic cylinder 150 is used to drive the fork seat 120 to move along the third guide rail 111. The fourth hydraulic cylinder 150 enables the forks 130 to move stably and accurately left and right along the fork carriage 110, which can help the forks 130 quickly find the insertion position, especially in relatively confined spaces, thus avoiding the need to move the forklift 200 and improving the efficiency of forklift transportation.
[0057] In the above embodiments, a roller 160 may also be included, with the fork holder 120 rolling on the third guide rail 111 via the roller 160. It is understood that the fork holder 120 indirectly bears the weight of the goods, and the pressure exerted by the fork holder 120 on the third guide rail 111 is relatively large. The rolling friction between the fork holder 120 and the third guide rail 111 can reduce friction and decrease the resistance to the movement of the fork holder 120 along the fork carriage 110. Furthermore, rolling friction causes less wear on the guide rail, making it suitable for frequent, long-term operation, effectively extending the service life of the equipment and reducing the company's equipment maintenance costs.
[0058] In the above embodiments, the top of the fork seat 120 can be designed as an open structure, and the first guide rail extends to the top of the fork seat 120. This design of the fork seat 120 facilitates the disassembly and maintenance of the stabilizing mechanism 140. Specifically, when the stabilizing mechanism 140 malfunctions, the connection between the first hydraulic cylinder 144 and the slide 143 can be disassembled first, and then the entire slide 143 can be directly removed from the open top along the first guide rail, thereby quickly removing the entire stabilizing mechanism 140 from the fork seat 120. After removal, the fork device 100 can continue to transport some goods that do not require stabilization. At the same time, the removed stabilizing mechanism 140 can be repaired without completely stopping the forklift 200. After the stabilizing mechanism 140 is repaired, the slide 143 can be reinserted from the top of the first guide rail, and the slide 143 and the first hydraulic cylinder 144 can be reconnected, thus quickly completing the disassembly, assembly, and maintenance process of the entire stabilizing mechanism 140.
[0059] In the above embodiments, the fork holder 120 may include a first fork holder 120 and a second fork holder 120. The first fork holder 120 and the second fork holder 120 are spaced apart along the length direction of the fork carriage 110, and each fork holder 120 is provided with a fork 130. The first fork holder 120 and the second fork holder 120 can move along the fork carriage 110 to adjust the distance between the two fork holders 120, so that the forks 130 connected to them can adapt to goods of different sizes, further improving the stability of the goods.
[0060] Furthermore, this utility model embodiment also provides a forklift 200, including the fork device 100 in the above embodiment. The fork device 100 is disposed at the front end of the forklift 200 and is used for forklifting goods. The fork device 100 includes a fork carriage 110, a fork seat 120, forks 130, and a stabilizing mechanism 140. The fork carriage 110 is configured to be connected to the front end of the forklift 200. The fork seat 120 is movably disposed on the fork carriage 110 along the length direction of the fork carriage 110. The forks 130 are mounted on the fork seat 120. The stabilizing mechanism 140 includes a pressure plate 141 and a hook 142. The first end of the pressure plate 141 is movably disposed on the fork seat 120 along the vertical direction. The hook 142 is movably disposed on the second end of the pressure plate 141 along the length direction of the pressure plate 141. In this embodiment, when the forklift 200 is transporting goods, the goods can be carried on the forks 130. By adjusting the position and height of the pressure plate 141 on the fork seat 120, the pressure plate 141 can be pressed against the top of the goods to initially stabilize them. At the same time, the extension distance of the hook 142 along the pressure plate 141 can be adjusted so that when facing goods of different volumes, the hook 142 can be hooked tightly to the front edge of the goods to prevent them from tipping forward, which greatly improves the stability of the goods and enhances the reliability and adaptability of the forklift 200.
