DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Refer to Figure 1-2, A lifting frame for preventing goods from falling off a forklift, including a support frame 6 installed at the front end of the forklift. Hydraulic telescopic members 7 are installed on both sides of the inner end of the support frame 6. The telescopic ends of the hydraulic telescopic members 7 are connected to a connecting frame 8. An outwardly protruding lifting frame 15 is installed on the lower side of the connecting frame 8. By driving the connecting frame 8 and the lifting frame 15 to rise or fall through the hydraulic telescopic members 7, the goods lifted by the lifting frame 15 can be correspondingly driven to rise or fall to the corresponding position.

[0021] Among them, the hydraulic telescopic member 7 (mainly including a hydraulic cylinder and a telescopic rod) is connected to the hydraulic system of the forklift itself.

[0022] Furthermore, a rotating rod 10 is rotatably connected inside the lifting frame 15. On both sides of the rotating rod 10, supporting plates 12 are fixedly connected through connecting ears 11. A horizontally arranged fork 13 is integrally formed at the bottom of the supporting plate 12. A driving motor 9 for driving the rotating rod 10 to rotate is installed on the side wall of the lifting frame 15. A flipping part that can drive the fork 13 to tilt upward is designed on the lifting frame 15. When the fork 13 forks up the goods, the driving motor 9 slowly drives the rotating rod 10 to rotate, driving the fork 13 to tilt upward. At this time, the goods are pressed against the supporting plate 12 under the action of gravity. When encountering a slope or an uneven ground, the goods will not fall off the fork 13, thus improving the safety during operation.

[0023] Furthermore, the width of the supporting plate 12 is greater than the width of the fork 13. The above design can increase the contact area between the supporting plate 12 and the goods, thereby improving the stability during handling. A silica gel pad 16 with the same size as the supporting plate 12 is adhered to the outer surface of the supporting plate 12. The silica gel pad 16 can reduce the impact force when the goods come into contact (collide) with the supporting plate 12, thereby playing an auxiliary protective role for the goods.

[0024] Furthermore, a detachable auxiliary lifting device is installed on the fork 13. The auxiliary lifting device includes two forklift slots 1 that can accommodate the fork 13. Connecting plates 3 are welded and fixed on the opposite sides of the forklift slots 1. A lifting arm 5 is installed at the upper end of the connecting plate 3 through a support arm. An anti-drop hook 4 is installed at the bottom of the front end of the lifting arm 5. A detachable auxiliary lifting device is designed on the fork 13. When it is necessary to lift goods such as ton bags or other goods, the auxiliary lifting device can be installed on the fork 13, and the goods can be lifted to the desired position by using the anti-drop hook 4 on the auxiliary lifting device, which can greatly increase the functionality of the forklift itself while adding very little cost.

[0025] In addition, when the fork 13 tilts, the lifting arm 5 itself also tilts, which can additionally increase the overall lifting height.

[0026] Further, a threaded hole 14 is vertically formed at the front end of the fork 13, and a light hole is formed on the forklift slot 1 corresponding to the threaded hole 14. The fork 13 and the forklift slot 1 are fixed together by a screw rod 2. The accessory sling can be fixed to the fork 13 by the screw rod 2 to prevent the accessory sling from falling off the fork 13.

[0027] In addition, when only using the fork 13 for handling, the screw rod 2 can also be installed on the fork 13 as an auxiliary limiting part for the goods.

[0028] Further, a turning handle is integrally provided at the upper end of the screw rod 2. The turning handle enables the installation and disassembly of the screw rod 2 without tools, making the installation and disassembly more convenient.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
