[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1-4 The embodiment of the present application provides a road ditch cover plate extraction device, which comprises a mounting plate 1, a socket 2 is fixedly arranged on the upper surface of the mounting plate 1, a rotating column 5 is rotatably arranged on the surface of the mounting plate 1, a connecting rod 4 is connected to the inner side of the mounting plate 1, the mounting plate 1 and the socket 2 are fixedly connected, a threaded column 3 is rotatably arranged on the surface of the socket 2, an anti-skid pressure seat 13 is fixedly connected to the lower end of the threaded column 3, and the socket 2 and the threaded column 3 are screw-connected.

[0023] ​Specifically, the mounting plates 1 on the left and right sides are tightly connected together by the connecting rod 4 to form a stable structure. On the surface of each mounting plate 1, there are two sets of rotating rods, one in the front and one in the back. The design of these rotating rods makes the whole device more flexible and adaptable. In order to further enhance the stability of the installation, sockets 2 are also fixedly installed on the surface of the mounting plate 1. The function of these sockets 2 is to safely install the mounting plate 1 on the front fork of the forklift. In addition, the sockets 2 are specially designed with threaded connections, and threaded posts 3 are connected by threads. This design not only increases the strength of the connection, but also facilitates operation. When installation is required, simply rotate the threaded post 3 and press the anti-slip pressure seat 13 downward, which can ensure that the socket 2 is stably installed with the front fork, thereby ensuring the safety and reliability of the entire device during use.

[0024] A synchronous motor 6 is fixedly connected to the top of the rotating column 5, and a connecting rod 7 is fixedly connected to the lower end of the rotating column 5. A sliding groove 11 is fixedly opened on the surface of the connecting rod 7. Folding rods 8 are rotatably connected to both sides of the connecting rod 7. A return spring 10 is connected to the inner side of the folding rod 8. A slider 9 is rotatably connected to the upper end of the folding rod 8. A rotating shaft 12 is provided between the folding rod 8 and the slider 9. The rotating column 5 and the connecting rod 7 are fixedly connected, and the lower end of the connecting rod 7 and the folding rod 8 are rotatably connected. The upper end of the folding rod 8 forms a sliding structure with the sliding groove 11 on the surface of the connecting rod 7 through the slider 9, and the folding rod 8 forms a rotating structure with the slider 9 through the rotating shaft 12.

[0025] Specifically, a rotating structure is formed between the rotating column 5 and the mounting plate 1. This structure allows the rotating column 5 to rotate freely. To achieve this rotation, the rotating column 5 is driven by a synchronous motor 6. During operation, the synchronous motor 6 works closely with the synchronous controller to ensure that the four sets of rotating columns 5 can rotate synchronously in a coordinated manner. This synchronous rotation can effectively change the direction of the rotating column 5 and the connected lower rotating rod 7. The surface of the connecting rod 7 is designed with a sliding groove 11. The sliding groove 11 and the upper end of the folding rod 8 are slidably connected by a slider 9. Rotating structures are constructed at the upper, middle, and lower ends of the folding rod 8. Thus, when the rotating column 5 drives the connecting rod 7 to change direction during rotation, the folding rod 8 can rotate accordingly. When the forklift's front fork lifts, it will drive the mounting plate 1. As the trench cover moves upward, it applies downward pressure to the folding rod 8. The folding rod 8 then slides along the groove 11 via the slider 9. Simultaneously, the coordinated operation of the three rotating structures at the top, middle, and bottom of the folding rod 8 allows it to fold and span across the bottom of the trench cover. With the assistance of the connecting rod 7, the folding rod 8 hooks onto the trench cover for extraction. Furthermore, when the folding rod 8 folds, it compresses the return spring 10. During the lowering of the trench cover, the rotation of the rotating column 5 removes the folding rod 8 from the bottom of the trench cover, thus releasing pressure. Under the action of the return spring 10, the folding rod 8 returns to its original position, and the slider 9 slides back to the upper end of the groove 11. Then, the forklift can continue to raise the forks, removing the connecting rod 7 from the gaps on both sides of the trench cover, preparing for the extraction of the next set of trench covers.

[0026] The working principle of this utility model is as follows:

[0027] When using this utility model, firstly, the forklift driver inserts the forklift's front fork into the socket 2 on the mounting plate 1, and by rotating the threaded column 3, uses the threaded connection to firmly press the anti-slip pressure seat 13 onto the front fork, ensuring that the entire device is securely installed on the forklift. Then, the driver moves the forklift to the position of the trench cover to be lifted, inserts the connecting rod 7 through the gaps on both sides of the trench cover, and the synchronous motor 6 drives the rotating column 5 to rotate. Adjusting the direction of the rotating column 5 and its lower end connection, when the forklift's front fork is raised, it will cause the mounting plate 1 and the entire lifting device to move upwards. During this process, the trench cover will apply downward pressure to the folding rod 8, and the folding rod 8 will slide along the groove 11 on the connecting rod 7 via the slider 9. Simultaneously, the upper, middle, and lower ends of the folding rod 8... The rotating structure works in tandem, allowing the folding rod 8 to fold flexibly and span across the bottom of the trench cover. At this point, the folding rod 8 hooks onto the trench cover, enabling its extraction. During extraction, the synchronous motor 6 drives the rotating column 5 to rotate synchronously, ensuring that the four sets of rotating columns 5, as well as the connecting rod 7 and folding rod 8 connected to them, work in a coordinated manner, improving extraction efficiency. When the trench cover needs to be lowered, the rotation of the rotating column 5 will remove the folding rod 8 from the bottom of the trench cover, releasing the pressure on the trench cover. Under the action of the return spring 10, the folding rod 8 will automatically return to its original position, and the slider 9 will slide back to the upper end of the slide groove 11, preparing for the extraction of the next set of trench covers. The entire device has a compact structure, is easy to operate, and can effectively improve the extraction efficiency of road trench covers while reducing manual labor intensity.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
