Limiting method and system for maximum lifting height of forklift

Abstract

The invention discloses a limiting method and system for the maximum lifting height of a forklift. The method comprises the following steps: introducing a lifting oil cylinder oil pressure value acquired by an oil pressure sensor in real time into an established first linear relationship model to obtain the current lifting cargo weight; introducing a bridge load of a back bridge acquired by a bridge load stress sensor in real time into an established second linear relationship model to obtain the current load central distance; introducing the current lifting cargo weight and the current load central distance into an established multiple regression model to obtain the maximum lifting height corresponding to the current lifting cargo weight and the current load central distance; and comparing the current lifting height acquired by a laser sensor in real time with the maximum lifting height and taking corresponding measures according to the comparison result. The affecting factors of themaximum lifting height comprise the lifting cargo weight and the load central distance. When the lifting cargo height exceeds the maximum lifting height, lifting is limited, so that overbearing operation and accidents can be prevented effectively.

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
