[0017] Reference Figure 1 , Figure 2 and Figure 4 A forklift wide-view fork monitoring device comprises a fork 1, a shelf 2 and a side shifter 7, wherein the shelf 2 is mounted on the upper end of the side shifter 7, and the fork 1 is mounted on the lower end of the side shifter 7;

[0018] The cargo fork 1, the shelf guard 2 and the side shifter 7 are conventional structures of a forklift, and structural improvements are not involved here, so the specific structures of the cargo fork 1, the shelf guard 2 and the side shifter 7 are not described in detail.

[0019] In this embodiment, a first camera 3 and a second camera 5 are respectively provided on both sides of the upper part of the shelf 2, and a third camera 8 is provided at the lower end of the side shifter 7 located in the middle of the fork 1. The first camera 3 and the second camera 5 are connected to the shelf 2 through an adjusting arm 4 whose installation interval can be adjusted left and right. A battery box 6 is installed inside the shelf 2, and the first camera 3, the second camera 5 and the third camera 8 are all connected to the battery box 6 through wires.

[0020] Obviously, when the fork 1 rises to pick up the goods, the third camera 8 located at the bottom monitors the bottom of the fork 1, and the first camera 3 and the second camera 5 located at a high position monitor the left and right sides above the fork 1 respectively. As the fork 1 rises, the operator can pay attention to the dynamics of the fork 1 and the goods in real time, realizing three-dimensional spatial monitoring of the fork 1 and the goods, bringing reliable protection for high-position picking and greatly reducing the probability of dangerous events.

[0021] In this embodiment, a camera mounting frame 9 is provided on the outer sides of the first camera 3 , the second camera 5 and the third camera 8 , and the first camera 3 , the second camera 5 and the third camera 8 can be mounted inside the camera mounting frame 9 by being rotated up and down.

[0022] Obviously, by rotating the first camera 3, the second camera 5 and the third camera 8 up and down, the monitoring range of the first camera 3, the second camera 5 and the third camera 8 in the spatial height direction can be adjusted, so that the monitoring device can adapt to forklifts of different height types to adjust the monitoring range.

[0023] In this embodiment, refer to Figure 3 The adjusting arm 4 includes a connecting frame 41 , and an adjusting slot 43 is formed in the connecting frame 41 along the length direction. The camera mounting frames 9 corresponding to the first camera 3 and the second camera 5 can be slidably mounted inside the adjusting slot 43 .

[0024] Obviously, the left-right interval between the first camera 3 and the second camera 5 can be adjusted through the adjustment slot 43, so that the monitoring device can adjust the monitoring range to suit forklifts of different widths.

[0025] In this embodiment, the upper ends of the camera mounting frames 9 corresponding to the first camera 3 and the second camera 5 are rotatably connected to the adjustment slots 43 and are tightened and fixed by fixing bolts 42 .

[0026] Obviously, the first camera 3 and the second camera 5 can be rotated left and right, so that the monitoring range of the first camera 3 and the second camera 5 can be further fine-tuned for forklifts of different width types, making the monitoring range of the first camera 3 and the second camera 5 more accurate.

[0027] In another embodiment, the left-right and up-down monitoring ranges of the first camera 3 and the second camera 5 are adjustable, and the spacing is adjustable, so that the device can adapt to monitoring forklifts of different heights and widths.

[0028] In this embodiment, the camera mounting bracket 9 includes a U-shaped plate, a U-shaped groove for mounting the camera is provided inside the U-shaped plate, and bolts for tightening and fixing the camera are installed on both sides of the U-shaped groove.

[0029] Obviously, installing the camera through the U-shaped groove and then fixing the camera with bolts is convenient for operation and has a simple structure.

[0030] In summary: This device forms a three-dimensional spatial monitoring of the forks by setting up three groups of cameras, with the cameras being set at high positions on the left and right and low in the middle, which provides reliable protection for high-position cargo pickup and greatly reduces the probability of dangerous incidents. At the same time, the cameras located on both sides of the high position can be adjusted in left and right spacing during installation, and can be rotated left and right and up and down, which is convenient for adjusting the monitoring area of ​​the camera according to different vehicle models. It is suitable for forklifts of different models, and has a simple structure, which is easy for staff to operate.
