When handling goods, the driving motor 71 can be controlled to work as needed to drive the driving shaft 7 to rotate, so that the first bevel gear 72 drives the second bevel gear 91 to rotate, so that the two bidirectional lead screws 9 rotate simultaneously to drive the movable blocks 10 to approach each other along the chutes 8. The connecting rods 13 rotate to drive the support frames 12 and the support rollers 11 away from the forklift fork 5, so that the support rollers 11 assist the forklift fork 5 to support the goods, realizing an increase in the support width. The goods are lifted by the hydraulic lifting frame 4, and the Mecanum wheels 2 are used to realize the lateral and oblique walking of the forklift body 1, improving the flexibility of the movement of the forklift body 1.
[0025] When working, the protective frame 3 encloses the forklift body 1 and the Mecanum wheels 2 to prevent damage to the forklift body 1 and the Mecanum wheels 2 caused by collisions with obstacles. At the same time, the spring shock absorber 31 buffers the impact received by the protective frame 3 to protect the forklift body 1. When handling goods, the driving motor 71 can be controlled to work as needed to drive the driving shaft 7 to rotate, so that the first bevel gear 72 drives the second bevel gear 91 to rotate, so that the two bidirectional lead screws 9 rotate simultaneously to drive the movable blocks 10 to approach each other along the chutes 8. The connecting rods 13 rotate to drive the support frames 12 and the support rollers 11 away from the forklift fork 5, so that the support rollers 11 assist the forklift fork 5 to support the goods, realizing an increase in the support width. The goods are lifted by the hydraulic lifting frame 4, and the Mecanum wheels 2 are used to realize the lateral and oblique walking of the forklift body 1, improving the flexibility of the movement of the forklift body 1, reducing the turning and steering requirements during the loading process, thereby reducing the risk of rollover and improving the stability of the load.
[0026] Through the above steps, the rotation of the connecting rod 13 drives the support frame 12 and the support rollers 11 away from the forklift forks 5, realizing an increase in the support width. The Mecanum wheels 2 are used to achieve the lateral and oblique walking of the forklift body 1, reducing the turning and steering requirements during the loading process, so as to solve the problems that when handling relatively wide goods, the lifting of the goods is likely to be unstable due to the misalignment of the forklift forks, and the forklift is also prone to rollover during the turning and steering of the loaded goods, posing certain potential safety hazards.
