Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-Figure 3A new type of anti-collision top frame structure shown in FIG, includes a top frame 1, a protective beam 2, the number of the protective beams 2 is six, and the protective beams 2 are fixedly connected to the inner wall of the top frame 1, and a plurality of arc-shaped grid plates 3 are connected to one side of the top frame 1, and the arc-shaped inner wall of the arc-shaped grid plate 3 is arranged toward the top frame 1, wherein the interior of the two protective beams 2 is provided with an empty slot 4, and a slider 5 is slidably installed inside the empty slot 4, and a spring 6 is connected to one side of the slider 5, and the other end of the spring 6 is connected to the inner wall of the empty slot 4, and an opening 7 is provided at the bottom of the empty slot 4, and the size of the opening 7 is smaller than the size of the empty slot 4, and the bottom of the slider 5 is fixedly connected to a movable rod 8, and the movable rod 8 slides It is arranged on the opening 7, and the bottom of the top frame 1 is fixedly connected to two connecting frames 9, and the connecting frames 9 are symmetrically arranged at the bottom of the top frame 1. The upper and lower ends of one side of the connecting frame 9 are respectively movably connected with a hinge rod 10 and a hinge rod 2 11. There are multiple hinge rods 10 and hinge rod 2 11, and the two ends of the hinge rod 10 and the hinge rod 2 11 are hinged to each other. One end of the hinge rod 10 is fixedly connected to the movable rod 1 8, and the positions where the hinge rod 10 and the hinge rod 2 11 overlap are connected by a rotating shaft, and a protective plate 12 is connected to the rotating shaft. Two movable rods 2 13 are provided on the arc grid plate 3, and the movable rod 18 and the movable rod 2 13 are connected by a movable buckle;

[0023] The end of the movable rod 1 8 is provided with a clamping head 14, and the movable rod 2 13 is provided with a plurality of clamping slots 15. The clamping head 14 is adapted to the size of the clamping slots 15. The clamping slots 15 on the movable rod 2 13 are arranged in an array along its axial direction.

[0024] The top frame 1 is a "mouth"-shaped frame structure, and the protective beams 2 are evenly distributed inside the top frame 1;

[0025] In the initial state, the protective beam 2 is fixed to the inner wall of the top frame 1, providing a basic protective structure for the top frame. The arc-shaped grid plate 3 is designed with its arc-shaped inner wall facing the top frame 1, which reduces the direct exposure of the straight corners of the top frame 1 and reduces the risk of collision. At this time, the spring 6 is in a natural state, the slider 5 is relatively stable in the slot 4, the movable rod 1 8 maintains a certain position in the opening 7, the hinge rod 1 10, the hinge rod 2 11 and the protective plate 12 are also in a relatively static initial position, together constituting the initial protection system of the top frame structure.

[0026] When the forklift is ready to work, the forklift operator pulls the movable rod 1 8 to make the movable rod 1 8 and the movable rod 2 13 contact each other, and the clamping head 14 is engaged with the clamping groove 15, so that the movable rod 1 8 and the movable rod 2 13 as well as the top frame 1 and the arc-shaped grid plate 3 form a stable triangular structure, thereby improving the stability of the top frame 1 structure and improving safety.

[0027] When the forklift operator pulls the movable rod 8, the hinge rod 10 and the hinge rod 2 11 move together with the movable rod 8. At this time, the hinge rod 10 and the hinge rod 2 11 gradually unfold, and the protective plate 12 blocks the left and right sides of the cab, thereby preventing the goods from directly hitting the forklift operator. After the forklift is finished working, the clamping head 14 and the clamping slot 15 are released, and the movable rod 8 returns to its original position due to the elastic effect of the stretched spring 6, thereby realizing the folding of the protective plate 12. The structure is simple, easy to operate, and highly safe.

[0028] The base 16 is fixedly mounted on the arc-shaped grid plate 3, and the movable rod 13 is rotatably mounted on the base 16;

[0029] The combination of protective crossbeam 2 and curved grating 3 provides multi-faceted protection. As the primary lateral support structure, protective crossbeam 2 increases the overall strength of top frame 1, preventing it from easily deforming in the event of a collision. The curved design of curved grating 3 effectively reduces the sharpness of top frame 1's corners, reducing the likelihood of injury or damage to personnel and equipment in a direct collision. Whether impacting vertically or at an angle, this structure provides superior protection, fully safeguarding personnel and equipment beneath the top frame. The rotatable mounting arrangement of movable bar 2 13 allows for easy interlocking with movable bar 1 8, enhancing practicality.

[0030] Two reinforcement rods 17 are fixedly connected to the inner wall of the top frame 1, and the reinforcement rods 17 are installed through the protective beam 2;

[0031] The reinforcement rod 17 establishes a more direct and more stable connection between the top frame 1 and the protective beam 2. When subjected to external forces, such as when the top frame 1 is hit from the side or pressed by heavy objects above, the reinforcement rod 17 can effectively transmit and disperse stress. It can prevent the protective beam 2 from displacing or deforming relative to the top frame 1, ensuring that the entire frame structure maintains a stable geometric shape, thereby enhancing the overall deformation resistance of the top frame structure.

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
