AI Technical Summary
The limit blocks of existing forklift collision protection devices cannot be effectively adjusted, making it difficult to adapt to cargo limit requirements of different lengths and specifications, resulting in the cargo being easily deviated or dropped during transportation.
A forklift collision protection device is designed. By setting a driven sprocket and a driving sprocket on the fork, and using a driving motor to drive the connecting shaft to rotate, the transmission chain is operated simultaneously, thereby flipping the limit plate from the horizontal state to the vertical state, realizing the effective limit of the cargo. The position of the limit plate can be adjusted through the operating distance of the transmission chain to adapt to cargo of different lengths.
The vertical state of the limit plate can achieve effective limits on goods, avoid the goods sliding towards the front end of the fork, prevent the goods from falling, and be able to adapt to goods of different lengths, improving the flexibility and effectiveness of limits.

[0017] like Figure 1-Figure 4 As shown, a forklift collision protection device comprises two driven sprockets 2 symmetrically rotatably mounted on opposite sides of two forks 1 of the forklift near the outer ends, two driving sprockets 3 symmetrically rotatably mounted near the inner ends of the two forks 1, and a driving motor 4 for driving the two driving sprockets 3 to rotate is mounted on the back side of one of the forks 1.
[0018] Specifically, two mounting plates 5 are fixedly provided symmetrically along the vertical direction at the back side of the two forks 1 near the lower end, and the driving motor 4 is fixedly installed on the outer side of one of the mounting plates 5. A connecting shaft 6 is rotatably installed between the two mounting plates 5, and the driving shaft of the driving motor 5 is connected to the corresponding end of the connecting shaft 6, and the two driving sprockets 3 are symmetrically installed on the connecting shaft 6.
[0019] A transmission chain 7 is installed between the driving sprocket 3 and the driven sprocket on the corresponding side, and the upper surface of the transmission chain 7 is lower than the upper surface of the fork 1, and the lower surface is higher than the lower surface of the fork 1. The upper outer sides of the two transmission chains 7 are fixedly provided with a limit plate 8 perpendicular thereto. In the middle of this embodiment, each limit plate 8 is fixedly connected to the outer side of the corresponding transmission chain 7 through a connecting block 9.
[0020] In addition, the two forks 1 are respectively fixed with an upper protective plate 10 and a lower protective plate 11 above and below the corresponding transmission chain 7.

Figure 1 As shown, the two limit plates are located at the front end of the two driven sprockets of the two transmission chains. When the fork loading is completed and the goods on the fork are transferred, the driving motor drives the connecting shaft to rotate, so that the two sets of transmission chains run synchronously, thereby flipping the two limit plates from the horizontal state to Figure 2 In the vertical state shown, the two limit plates effectively limit the cargo on the fork, preventing the cargo from sliding toward the front end of the fork, thereby preventing the cargo from falling.
