[0019] Please refer to Figures 1-3 A forklift safety monitoring auxiliary device, comprising a fork frame 1, two symmetrically distributed fork arms 2 are installed on the movable frame, the bottom of the fork arm 2 is provided with a first pad 3 and a second pad 4, further comprising:

[0020] A first sliding cavity 5 is opened on the outer side of the second pad 4, and a second sliding cavity 9 is opened on the side of the second pad 4 away from the first pad 3, a first sliding frame 6 is slidably arranged in the first sliding cavity 5, a first camera 7 is installed in the first sliding frame 6, a second sliding frame 10 is slidably arranged in the second sliding cavity 9, and a second camera is installed in the second sliding frame 10.

[0021] A driving mechanism is arranged in the second pad 4, used for driving the movement of the first sliding frame 6 and the second sliding frame 10.

[0022] When a pair of fork arms 2 are used for transporting goods, if the fork arms 2 are loaded with over-height goods and cause visual obstruction to the forklift driver, the first sliding frame 6 in the first sliding cavity 5 and the second sliding frame 10 in the second sliding cavity 9 are driven by the driving mechanism to extend out of the second pad 4, so that the first camera 7 on the first sliding frame 6 can monitor the road conditions in front of the fork arms 2, and at the same time the second camera on the second sliding frame 10 can monitor the road conditions on the side of the fork arms 2, so as to assist the forklift driver to understand the specific conditions of the road in front of the forklift, facilitate the safe driving of the forklift driver, and when the fork arms 2 transport goods that are not over-height, the goods will not obstruct the driving field of view of the driver, at this time the first sliding frame 6 and the second sliding frame 10 are driven by the driving mechanism to enter the first sliding cavity 5 and the second sliding cavity 9, so as to protect the first camera 7 on the first sliding frame 6 and the second camera on the second sliding frame 10, avoid damage caused by long-term exposure to the collision of transported goods, prolong the service life of the monitoring auxiliary device, and make the monitoring auxiliary device more flexible to use.

[0023] In one case of the embodiment, the first sliding frame 6 is provided with a first top cover 8 which is attached to the inner wall of the first sliding cavity 5, and the second sliding frame 10 is provided with a second top cover 11 which is attached to the inner wall of the second sliding cavity 9.

[0024] The first top cover 8 can protect the outer end of the first sliding frame 6, and when the first sliding frame 6 is received in the first sliding cavity 5, the first top cover 8 can block the port of the first sliding cavity 5, so that dust or foreign matter cannot enter the first sliding cavity 5. The second top cover 11 can protect the front of the second sliding frame 10, and when the second sliding frame 10 is received in the second sliding cavity 9, the second top cover 11 can block the port of the second sliding cavity 9, so that dust or foreign matter cannot enter the second sliding cavity 9.

[0025] In one case of the embodiment, the first sliding cavity 5 and the second sliding cavity 9 are provided with a plurality of fixed cylinders 13, and the fixed cylinders 13 are slidably provided with movable rods 14. The movable rods 14 located in the first sliding cavity 5 are connected to the first sliding frame 6, and the movable rods 14 located in the second sliding cavity 9 are connected to the second sliding frame 10.

[0026] The fixed cylinders 13 and the movable rods 14 make the first sliding frame 6 and the second sliding frame 10 more stable when they slide in the first sliding cavity 5 and the second sliding cavity 9.

[0027] In one case of the embodiment, the inner walls of the first sliding cavity 5 and the second sliding cavity 9 are provided with limit blocks 12.

[0028] The limit blocks 12 can limit the positions of the first sliding frame 6 and the second sliding frame 10 in the first sliding cavity 5 and the second sliding cavity 9.
