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

Abstract

The invention discloses a method and system for limiting the maximum lifting height of a forklift. The method includes: substituting the oil pressure value of the lifting cylinder collected by the first oil pressure sensor in real time into the established first linear relationship model to obtain the current weight of the lifted goods; Substituting the oil pressure value of the front chamber of the inclined cylinder collected by the second oil pressure sensor in real time and the oil pressure value of the rear chamber of the inclined cylinder collected by the third oil pressure sensor in real time into the second linear relationship model established to obtain the current load center distance; The weight of the lifted cargo and the current load center distance are substituted into the established multiple regression model to obtain the maximum lift height corresponding to the current lift cargo weight and the current load center distance; the current lift height collected in real time by the laser sensor is compared with the maximum lift height The lift heights are compared, and corresponding actions are taken according to the comparison results. When the lifting height exceeds the maximum lifting height, the present invention restricts the lifting and can effectively prevent overloading operations and accidents.

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 ...
