[0002] Forklifts play a very important role in the logistics system of enterprises. Especially with the rapid development of China's economy, the material handling of most enterprises has been separated from the original manual handling, and replaced by mechanized handling mainly based on forklifts. Therefore, in the past few years, the demand for China's forklift market has grown at a double-digit rate every year, especially when transporting chemicals to chemical warehouses. The forklift driver sitting in the driver's seat of the forklift cannot accurately grasp the distance from the obstacles in front, behind, left and right. There are often obstacles or people walking within the working range of the forklift, and the driver needs to accurately grasp the distance between the vehicle and obstacles and people. Especially when there are goods piled up in front of the forklift, the goods seriously affect the operator's line of sight. When transporting goods, multiple people are required to cooperate, which reduces the efficiency of transporting goods and increases the cost of use. Therefore, a forklift anti-collision protection device is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-6 As shown, a forklift collision protection device of the present invention comprises a forklift body 1, two cameras 10 and two display screens 11, the two cameras 10 are both mounted on the left side of the forklift body 1, the two display screens 11 are both mounted inside the forklift body 1, a fixed frame 12 is mounted on the left side of the forklift body 1, a lifting frame 13 is slidably mounted on the left side of the fixed frame 12, two forks 14 symmetrically distributed front and back are fixedly mounted on the left side of the lifting frame 13, a rotating groove 15 is provided on the upper side of the two forks 14, and a limit plate 16 is rotatably mounted in the two rotating grooves 15, the two cameras 10 are respectively mounted on the left side of the two limit plates 16, a square opening 17 is provided on the upper side of the two forks 14 close to the lifting frame 13, an elliptical plate 18 is rotatably mounted in the two square openings 17, the two elliptical plates 18 and the two limit plates 16 rotate in opposite directions, and the two forks 14 are provided with a control component matching the limit plate 16 and the elliptical plate 18;

[0022] When the utility model is not in use, the limit plate 16 is completely located inside the rotating groove 15 under the control of the control component, and the elliptical plate 18 is in a vertical state under the action of the control component, which is convenient for the operator to drive the forklift body 1 to transport goods;

[0023] When the utility model is used, the operator inserts the fork 14 into the lower side of the pallet and pushes the elliptical plate 18 to a horizontal state. The elliptical plate 18 makes the limit plate 16 in a vertical state through the control component. When there is a lot of cargo on the upper side of the fork 14, the operator's field of vision is blocked. The operator starts the two cameras 10 and the display screen 11 to display the field of vision information in front of the two forks 14 through the cameras 10 and the display screen 11, so that the operator can control the movement of the forklift body 1, facilitate the transportation of cargo, and avoid accidents.

[0024] The utility model controls the limit plate and the elliptical plate to rotate through the control component. When the cargo fork is loaded with cargo, the limit plate is in a vertical state. The camera displays the information in front of the cargo fork through the display screen, which is convenient for the operator to control the forklift to move, thereby facilitating the transportation of cargo without the need for command by other personnel, reducing the cargo transfer cost and improving the efficiency of transporting cargo.

[0025] The control assembly includes a long slot 20 opened on the lower side of the fork 13 and connected to the square slot 14. A long rod 21 is rotatably mounted in the long slot 20. A connecting rod 22 is hingedly connected between the left side of the long rod 21 and the limit plate 16. An arc rod 23 is hingedly connected between the right side of the long rod 21 and the elliptical plate 18. A square slot 24 matching the long rod 21 is opened on the right side of the long slot 20. A square plate 25 matching the square slot 24 is fixedly arranged on the right side of the long rod 21. A plurality of first springs 26 symmetrically distributed frontward and rearward are fixedly arranged between the lower side wall of the square plate 25 and the side wall of the square slot 24.

[0026] When the utility model is not in use, under the elastic action of the first spring 26, the long rod 21 is in an inclined state with the left side lower and the right side higher, and under the push of the arc rod 23, the elliptical plate 19 is in a vertical state, and under the pull of the connecting rod 22, the limit plate 16 is in a horizontal state, which is convenient for the fork 14 to load the goods, ensuring the smooth use of the device;

[0027] When the utility model is used, when the operator controls the forklift body 1 to insert the fork 14 into the lower side of the cargo, the right side of the cargo abuts against the left side of the elliptical plate 18. As the fork 14 continues to move, the cargo pushes the elliptical plate 18 to rotate. The elliptical plate 18 rotates clockwise through the right side of the long rod 21 through the arc rod 23, so that the first spring 26 is compressed, and the left side of the long rod 21 rotates clockwise synchronously. The long rod 21 pushes the limit plate 16 to rotate through the connecting rod 22. After the elliptical plate 18 rotates to completely fit the cargo, the limit plate 16 rotates to a vertical state. The operator starts the two cameras 10 and the display screen 11 to observe the environmental conditions in front of the fork 14, which is convenient for use.

[0028] Furthermore, the limiting plate 16 limits the lower side of the cargo to prevent the cargo from moving left and right, thereby ensuring smooth transportation of the cargo.

[0029] A buffer is provided on the left side of the two forks 14. The buffer includes a buffer groove 30 opened on the left side of the fork 14. A block 31 is slidably mounted in the buffer groove 30. A plurality of linearly distributed second springs 32 are fixedly provided between the side wall of the block 31 and the side wall of the buffer groove 30. A buffer block 33 matching the fork 14 is fixedly provided on the left side of the block 31. When the fork 14 collides with an object, the buffer block 33 first weakens the collision force, and then the second spring 32 weakens the collision force, thereby avoiding the shaking of the goods on the fork 14, and protecting the collided object synchronously, thereby ensuring the safe operation of the device.

[0030] Furthermore, the left sides of the two buffer blocks 33 are both processed into a trapezoidal shape, which facilitates the insertion of the fork 14 into the pallet or the lower side of the cargo, thereby improving the ease of use of the device.

[0031] A plurality of elastic telescopic rods 40 symmetrically distributed front and back are fixedly provided on the right side of the forklift body 1, and a protective plate 41 is fixedly provided on the output ends of the plurality of elastic telescopic rods 40 located on the same side front and back; the rear side of the forklift body 1 is protected to prevent the rear side of the forklift body 1 from being damaged.

[0032] The two display screens 11 are symmetrically distributed front to back, and the contents of the two cameras 10 are displayed in a distributed manner, so as to facilitate observation by operators.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
