Fork truck as well as anti-tipping control method and anti-tipping control system thereof

Abstract

The invention discloses an anti-tipping control method used for a fork truck. The control method comprises the following steps: 1, detecting attitude parameters of the fork truck in real time; 2, judging whether the fork truck is in a stable state or not according to a detection result obtained in the step 1, if so, executing step 3; otherwise, executing step 4; 3, continuing carrying out a current operation; and 4, controlling a gantry, reducing lift height or / and reducing declination angle of the gantry. Through adoption of the method, deviation correction can be carried out on the fork truck immediately when the fork trunk is detected to be in an unsteady state, so as to ensure that tipping of goods or the tipping of the whole fork trunk can be avoided, thereby enhancing operation stability and reliability of the fork truck. The invention also provides an anti-tipping control system and a fork truck which comprises the system and has a corresponding technology effect.

Description

technical field [0001] The invention relates to the technical field of port machinery, in particular to an anti-overturn control method and an anti-overturn control system for forklifts. Besides, the present invention also relates to a forklift comprising the above-mentioned anti-rollover control system. Background technique [0002] With the rapid development of my country's port logistics throughput, the turnover cycle of port goods is getting shorter and shorter. Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Forklifts have the characteristics of strong lifting capacity and flexible operation, and they have an irreplaceable position in distribution centers such as storage yards and ports. [0003] A forklift is mainly composed of an engine, a traveling mechanism, a car body, a lifting mechanism, a hydraulic system and electrical equip...

AI Technical Summary

Problems solved by technology

[0004] In the operation of forklifts, because the materials forklifted by the forklift basically have no protection measures, when the weight of the goods is heavy, and the lifting height of the mast is high and the inclination angle is large, it is often easy to cause the material to overturn due to excessive load torque. The phenomenon of overturning or falling, in severe cases, the entire forklift will also overturn, which will not only bring huge loss of goods and property, but also bring great hidden dangers to the personal safety of operators
