A method and system for automatically adjusting the working posture of a forklift working device

Abstract

The invention provides an automatic adjustment control method and system for operation posture of a forklift working device. The method comprises the steps that after a forklift completes material collection, the initial posture value of the forklift working device is obtained; after the initial posture value is obtained, the posture measurement value of the forklift working device is collected inreal time; the difference value between the posture measurement value of the forklift working device and the initial posture value is calculated in real time, and a control signal of the forklift working device is generated according to the difference value; and the posture of the forklift working device is adjusted in real time according to the control signal, so that the posture change of the forklift working device is kept within a preset range. According to the automatic adjustment control method and system for the operation posture of the forklift working device, the posture of the forklift working device can be adjusted in real time according to the change of the forklift driving road surface, so that the forklift keeps the following control of the angle of the working device on road surface bumping in the driving process, and the influence of road surface bumping on the posture of the working device is offset.

Description

technical field [0001] The invention relates to the technical field of forklift control, in particular to a method and system for automatically adjusting the working attitude of a forklift working device. Background technique [0002] Forklift is a kind of material handling machinery, which is used for material stacking, short-distance transportation, loading and unloading, transition and other occasions. Its working devices include mast, lifting cylinder, tilting cylinder and accessories. [0003] When the forklift is driving with cargo, due to the bumpy road surface, the mast will bump along with the whole vehicle, which will cause the materials in the mast to slip, which affects the working efficiency of the forklift and also affects the safety of the forklift. [0004] At present, there is no feasible control scheme in the prior art that can actively and real-time control the attitude of the working device of the forklift to offset the impact of road bumps on the forklif...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method and system for automatically adjusting the working attitude of the working device of the forklift, which can solve the problem that the whole machine, especially the mast, bumps along with the driving road during the working process of the forklift, and realize the adjustment of the working device of the forklift. The posture is actively controlled in real time to offset the impact of road bumps on the forklift mast, especially to offset the impact of road bumps on the forklift mast angle
