Forklift structure with adjustable axle distance

Abstract

The invention relates to the technical field of forklifts, solves the problem that in the prior art, when a pallet fork forks goods and ascends to the position, the forklift tilts forwards or even tilts over, and particularly discloses a forklift structure with adjustable axle distance, and the forklift structure comprises a chassis system, a portal frame system and a driving system. When the fork ascends, especially when the fork picks up the load, the fork ascends and the center of mass ascends, when the center of mass ascends in the front part of the forklift, it is easy to cause the forklift to tilt forward or overturn, thus when the fork ascends to a first preset height, the front wheel is controlled to move forwards through the first driving assembly, so that the axle distance between the front wheel and the rear wheel is adjusted, the front supporting point is moved forwards, and the forklift is prevented from leaning forward. Besides,due to the fact that the fork ascends at the moment, the front wheels move forwards and do not interfere with the fork located at the low position.

Description

technical field [0001] The invention relates to the technical field of forklift structures, in particular to a forklift structure with adjustable wheelbase. Background technique [0002] In order to realize the handling of goods or other objects in a small area, forklifts are generally used instead of labor, which can save labor costs to a large extent and improve work efficiency, but the stacking height of goods often does not necessarily maintain the same level. Especially for the goods on some shelves, the shelves are generally divided into many layers, and the goods on the shelves are placed at different heights. In order to use the same forklift to pick and place goods at different heights, the forks are usually set It is a liftable form, using the lift of the fork to fork goods of different heights, but because the fork generally carries heavy goods, its up and down movement has a greater impact on the overall center of gravity, and when the fork is on the After the g...

[0002] In order to realize the handling of goods or other objects in a small area, forklifts are generally used instead of labor, which can save labor costs to a large extent and improve work efficiency, but the stacking height of goods often does not necessarily maintain the same level. Especially for the goods on some shelves, the shelves are generally divided into many layers, and the goods on the shelves are placed at different heights. In order to use the same forklift to pick and place goods at different heights, the forks are usually set It is a liftable form, using the lift of the fork to fork goods of different heights, but because the fork generally carries heavy goods, its up and down movement has a greater impact on the overall center of gravity, and when the fork is on the After the fork has picked up the goods, its rise will cause the center of gravity to move up. Since the fork is located at the front end of the forklift, it is likely to cause the forklift to tilt forward or even tip over.
