[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1 and Figure 2As shown in one embodiment of the present invention, a safety protection device for a manual hydraulic forklift wheel includes a manual forklift 1 and a cylinder base 2 for mounting on the forklift. The cylinder base 2 is fixedly connected to the manual forklift 1 by bolts. A protective cover is installed on the cylinder base 2 to facilitate the stable installation of the protective cover at the wheel area below the forklift cylinder. The entire cover can be made of materials such as steel plate, aluminum alloy, or engineering plastics according to actual usage requirements, thereby forming effective protection around the wheel. By physically isolating the wheel assembly's working area, it prevents the operator's feet from approaching the danger zone and prevents foreign objects from being caught. It can effectively prevent the wheel from squeezing the operator's feet and also prevent foreign objects from getting caught, causing the wheel to jam and causing the goods on the forklift to slip or fall, resulting in personal injury or damage to the goods. This improves safety performance and eliminates safety hazards during forklift operation. The design eliminates all hidden dangers, reduces the risk of workplace injuries, and is highly adaptable to the cylinder base structure of mainstream hydraulic forklift models. Its simple structure and low unit production cost make it suitable for mass installation and widespread adoption. The protective cover includes a protective component 3 and a mounting base 4. The mounting base 4 is fixedly connected to the cylinder base 2 with screws. The lower part of the mounting base 4 is fixedly connected to the protective component 3, facilitating quick installation of the entire protective cover to the designated location for stable use and easy disassembly, inspection, and maintenance. The protective component 3 consists of a baffle 301 and a side plate 302. A soft lower guardrail 303 is fixedly connected to the lower end of the baffle 301 and side plate 302. The soft guardrail can be made of rubber, soft plastic, or other materials depending on actual needs. It can clean debris in front of the wheels, preventing the wheels from getting stuck due to debris. The rubber guardrail will not affect the use of the forklift due to slope.

[0033] It should be noted that reflective strips or warning colors (such as yellow stripes) can be set on the surface of the protective cover to achieve a warning effect and further improve safety. When the strength requirement of the protective cover is high, horizontal / vertical reinforcing ribs can also be added to the inside of the cover to improve impact resistance.

[0034] like Figure 2 As shown, in some embodiments, the mounting base plate 4 has a mounting port 401, which is configured to cooperate with the hydraulic cylinder on the manual forklift 1. The mounting base plate 4 is fixedly connected to the protective member 3 by screws, which facilitates the stable installation of the entire protective cover using the mounting base plate 4, improves the applicability of the protective cover, and facilitates quick and easy installation. The baffle 301 and the side plate 302 are fixedly connected by screws, which facilitates the stable connection of the two together to form a protective cover. The soft lower enclosure 303 is fixedly connected to the baffle 301 and the side plate 302 by screws, which facilitates blocking the gap between the lower part of the protective cover and the ground, enhancing the protective performance. At the same time, it forms a soft contact part between the protective cover and the ground, reducing wear between the protective cover and the ground, extending the service life, and ensuring stable use for a long time.

[0035] Example 2

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in Embodiment 1, when a user operates a forklift to move on the ground, if there is a protrusion on the ground that is taller than the gap between the protective cover and the ground, the protrusion will block the protective cover, preventing the forklift from moving forward normally. The user will need to maneuver the forklift around the protrusion, increasing their workload and making it inconvenient to use. Therefore, the protective cover, which cannot undergo deformation, is improved. The protective cover consists of two parts, upper and lower. When the lower part is subjected to external force, the lower cover can slide on the upper cover, increasing the gap between the bottom of the protective cover and the ground, allowing for smooth passage through the protrusion. The protective component 3 also includes a sliding plate 304, which is slidably connected to the frame-shaped protective cover formed by the baffle 301 and the side plate 302. A slider 3021 at a corresponding position on the side plate 302 is slidably connected to a groove 3041 on the sliding plate 304, facilitating movement of the sliding plate. When 304 is subjected to force, it can slide smoothly on the upper cover composed of baffle 301 and side plate 302, thereby increasing the distance between the bottom of the protective cover and the ground. When the external force is removed, the sliding plate 304 resets. In order to ensure that the sliding plate 304 can reset smoothly, a support spring can be installed on the upper part of the sliding plate 304 and the lower bracket of the mounting base plate 4, thereby ensuring the smooth reset of the sliding plate 304 and ensuring stable use. At the same time, the slider 3021 and the slide groove 3041 are used to limit the path of the sliding plate 304 sliding up and down, improving the stability of the sliding plate 304 sliding up and down, preventing the sliding plate 304 from sliding off, and ensuring stable use. The lower part of the sliding plate 304 is integrally provided with a connecting seat 3042. The connecting seat 3042 is equipped with a soft lower enclosure 303 and an abutment 305, which facilitates the stable installation of the two to the lower part of the sliding plate 304 and ensures stable use by mutual cooperation.

[0037] Both the flexible lower enclosure 303 and the contact element 305 are fixedly connected to the connecting seat 3042 by screws. The contact element 305 includes an arc-shaped contact plate 3051 and a connecting rod 3052. The connecting rod 3052 abuts against the flexible lower enclosure 303 and is fixedly connected to the connecting seat 3042 by screws. The arc-shaped contact plate 3051 is integrally formed at both ends of the connecting rod 3052. The arc-shaped contact plate 3051 is located at the edge of the protective element 3, and the side of the arc-shaped contact plate 3051 on the outer side of the protective element 3 is provided with... The curved abutment edge facilitates the formation of stable abutment components in both the forward and backward movement directions of the wheel body. When the forklift encounters a protrusion during movement, the abutment component 305 is the first component on the protective cover to contact the protrusion. As the abutment comes into contact, the stress is transferred from the abutment component 305 to the sliding plate 304, which in turn drives the sliding plate 304 to slide on the upper cover, increasing the distance between the bottom of the protective cover and the ground. This prevents the protrusion from blocking the protective cover, ensuring that the forklift can pass smoothly and guaranteeing the stable use of the protective cover.

[0038] Example 3

[0039] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, based on Embodiment 1, when foreign objects on the ground get caught between the wheel and the wheel frame during the wheel's rolling motion, the wheel may become stuck due to the action of the foreign objects, and in severe cases, the wheel may even become jammed, preventing the forklift from moving forward normally. Therefore, a matching anti-winding component is installed on the protective cover to clean up the foreign objects that are caught in time, preventing them from getting caught in and jamming the wheel, and ensuring that the forklift can drive smoothly and stably for a long time. The protective cover formed by the protective component 3 also contains an anti-winding component 5, which includes a movable blade 501 and a fixed blade 503. By using the cooperation between the two, a scissor-like component is formed at the wheel position. As the wheel rolls forward, the two tools continuously overlap and stagger. During the overlap process, the foreign objects caught in the wheel are cut into pieces, preventing them from getting caught in and tangled, and cleaning up the foreign objects caught in the wheel in time.

[0040] The movable blade 501 is fixedly connected to the fixed ring 502, which is in turn fixedly connected to the axle of the manual forklift 1. This facilitates the stable installation of the movable blade 501 onto the axle, allowing it to engage with the wheel. As the wheel rolls, the movable blade 501 rotates along with the wheel, thus working in conjunction with the fixed blade 503 to effectively cut and shred any foreign objects caught in the wheel. This ensures timely and effective removal of any foreign objects. The fixed ring 502 has a threaded hole 5022, into which a limit pin 5021 is threadedly connected. One end of the limit pin 5021... An insertion slot is provided to facilitate the smooth insertion of auxiliary tools into the slot during the installation of the limiting pin 5021. This drives the limiting pin 5021 to rotate in the threaded hole 5022, so that its end can only abut against the wheel axle, providing stable and effective limiting and fixing of the fixing ring 502. Furthermore, the limiting pin 5021 passes through the threaded hole 5022 and abuts against the wheel axle, ensuring that the limiting pin 5021 effectively limits the fixing ring 502 and the wheel axle. This ensures that the movable blade 501 can rotate stably along with the wheel axle during the cutting and crushing process of the foreign object.

[0041] The fixed blade 503 is fixedly connected to the connecting bracket 5041, which is integrally set at one end of the support rod 504, by screws. This facilitates the stable installation of the fixed blade 503 onto the baffle 301 of the protective cover using the support rod 504, allowing the fixed blade 503 to be used stably. It works in conjunction with the movable blade 501 to cut and crush foreign objects that have been rolled in. The end of the support rod 504 away from the fixed blade 503 is bent to form a connecting rod 5042. An adjustment slot is provided on the connecting rod 5042. The screw passes through the adjustment slot on the connecting rod 5042 and fixes the baffle 301 at a designated position. The cooperation of the screw and the connecting rod 5042 allows the support rod 504 to be stably installed on the baffle 301, thereby ensuring the stable installation of the fixed blade 503. The adjustment slot on the connecting rod 5042 allows the position of the support rod 504 to be adjusted appropriately during installation, ensuring that the fixed blade 503 and the movable blade 501 can work together smoothly.

[0042] It should be noted that the number of anti-winding parts 5 installed can be set according to actual needs. They can be installed on one side of the wheel or on both sides of the wheel, thus allowing for flexible use.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
