Forklift maximum lifting height limiting method and system

Abstract

The invention discloses a forklift maximum lifting height limiting method and system. The method comprises the steps that a lifting oil cylinder oil pressure value collected by a first oil pressure sensor in real time is substituted into a first linearity relation model set up to obtain the current lifting cargo weight; an oblique oil cylinder front cavity oil pressure value collected by a secondoil pressure sensor in real time and an oblique oil cylinder rear cavity oil pressure value collected by a third oil pressure sensor in real time are substituted into a second linearity relation modelset up to obtain the current load center distance; the current lifting cargo weight and the current load center distance are substituted into a multivariate regression model to obtain the maximum lifting height corresponding to the current lifting cargo weight and the current load center distance; and the current lifting height collected by a laser sensor in real time is compared with the maximumlifting height, and corresponding action is taken according to the compared result. According to the method and the system, when the lifting cargo height surpasses the maximum lifting height, liftingis limited, and overload operation and accidents can be effectively prevented from occurring.

Description

technical field [0001] The invention relates to the field of forklift safety, in particular to a method and system for limiting the maximum lifting height of a forklift. Background technique [0002] Forklifts are industrial handling vehicles that can load and unload palletized goods, stack them and transport them over short distances. Because they greatly improve work efficiency and reduce the labor intensity of workers, they have been more and more widely used. During the process of stacking goods by forklift, due to the different lifting heights of the mast, its carrying capacity is different. The higher the lifting, the weaker the carrying capacity. If the current lifting height of the forklift exceeds the maximum lifting height corresponding to the current lifting cargo weight and the current load center distance, the forklift is in danger during use. However, at present, in the operation of forklift trucks, there are basically no protective measures for the materials ...

AI Technical Summary

Problems solved by technology

However, at present, in the operation of forklift trucks, there are basically no protective measures for the materials forked by the forklift truck. It will cause tipping or falling, and in severe cases, the entire forklift will also tip over, which will not only bring huge loss of goods and property, but also bring great personal safety hazards to operators
