Pump truck as well as system and method for monitoring fatigue health condition of pump truck boom

Abstract

The invention discloses a system and a method for monitoring the fatigue health condition of a pump truck boom. According to the system and the method for monitoring fatigue health of the pump truck boom, the real-time stress condition of the pump truck boom is acquired according to pumping parameter information and boom posture information by acquiring the pumping parameter information and the boom posture information in real time, and finally, the fatigue attrition rate is calculated according to accumulated borne stress circulation times and the total fatigue life of the pump truck boom; an operator can know the current health condition of the pump truck boom according to the fatigue attrition rate, and further a measure is taken to reduce the operation risk of the pump truck and guarantee the operation efficiency; the invention further discloses a pump truck on the basis, and the system for monitoring the fatigue health condition of the pump truck boom is arranged on the pump truck.

Description

Technical field [0001] The invention relates to engineering machinery technology, in particular to a pump truck and a fatigue health monitoring system and method of the pump truck boom. Background technique [0002] The pump truck usually includes a chassis, a turret, a pumping system and a pump boom system. The pumping system is fixedly installed on the chassis, the turret is rotatably arranged on the chassis, and the pump boom system is connected to the turret. Through the action of the turret, the pump truck boom system can rotate relative to the chassis; the pump truck boom system includes a delivery pipeline and a pump truck boom, the delivery pipeline is arranged on the pump truck boom; the pump truck boom consists of multiple telescopic cylinders The first boom of the pump truck boom is hinged on the turret, and the telescopic cylinders are respectively arranged between the first boom and the turret and between adjacent boom sections. The action of the telescopic cylinder...

Problems solved by technology

However, the current monitoring of pump trucks is carried out by experimenters regularly bringing instruments and equipment to the pump truck for testing. The testing process is cumbersome and there are safety risks, and the obtained data is only the data value of a single time point, which cannot be completely tested. It shows the long-term working status of the whole machine, so it is impossible to monitor the mechanical stress and fatigue life for a long time, resulting in the inability to predict the upcoming failure, and it is impossible to warn the maintenance personnel before the failure occurs, and then miss to take preventive measures The best time to take action
