Stress real-time monitoring system applied to forklift truck body structure and control method thereof

Abstract

The invention discloses a stress real-time monitoring system applied to a forklift truck body structure, which comprises a stress-strain analyzer, a resistance strain gauge, a vehicle-mounted industrial personal computer, a display alarm and a forklift truck body, wherein a data output interface of the resistance strain gauge is connected with the stress-strain analyzer, an input interface of thevehicle-mounted industrial personal computer is connected with a data output interface of the stress-strain analyzer, and an output interface of the vehicle-mounted industrial personal computer is connected with the display alarm. The invention also discloses a control method of the stress real-time monitoring system applied to the forklift truck body structure. According to the method, the maximum load, the maximum stress and the position information of the maximum stress of the forklift under each working posture are obtained based on finite element analysis, the early warning and the activecontrol of the posture, the load and the stress of the forklift truck body under the working condition data of the forklift truck body are realized, an operator can know the safety of the forklift truck body structure in real time, a driver is guided to stop dangerous operations such as overload and over-angle, and the safety of the forklift truck body is improved.

Description

technical field [0001] The invention relates to the field of equipment production and research of forklift trucks, more specifically a stress real-time monitoring system and control method applied to the body structure of forklift trucks. Background technique [0002] Forklift trucks are mainly used for forklift transportation of stone blocks in stone mining areas. Due to the huge volume and weight of stone blocks and the complex environment of the mining area, the mechanical performance and safety requirements of forklift trucks are high. However, forklift trucks After a long time of using the stone fork, the load mechanism will experience structural wear and fatigue, resulting in structural breakage and production accidents. At present, there is no good method for the safety protection of the mechanical structure of the body of the forklift trucks in the market. We can only rely on the use time and experience to estimate the wear and fatigue of the mechanical structure, an...

[0002] Forklift trucks are mainly used for forklift transportation of stone blocks in stone mining areas. Due to the huge volume and weight of stone blocks and the complex environment of the mining area, the mechanical performance and safety requirements of forklift trucks are high. However, forklift trucks After a long period of use of the stone fork, the load mechanism will experience structural wear and fatigue, resulting in structural breakage and production accidents

At present, there is no good method for the safety protection of the mechanical structure of the body of the forklift trucks in the market. It can only rely on the use time and experience to estimate the wear and fatigue of the mechanical structure, which has risks in safety protection.
