A precise control system and control method for synchronous lifting main jack for aircraft

Abstract

The present invention discloses a precise control system and control method of synchronous lifting main jack for aircraft, comprising at least three main jacks, a PLC controller electrically connected to each main jack, and a control end electrically connected to the PLC controller; a servo driver is installed on each main jack, the servo driver is electrically connected to the servo motor of the main jack, a proportional valve and a solenoid valve are also provided on the pipeline connecting the servo motor and the main jack actuator, and a pull-wire sensor is also connected between the support head and the actuator of the main jack actuator; the servo driver, the proportional valve, the solenoid valve, and the pull-wire sensor are all electrically connected to the PLC controller. The present invention adopts an automated synchronous lifting form for the entire aircraft, which greatly reduces the labor intensity of maintenance personnel, shortens the maintenance and preparation time of military aircraft, and improves the economic benefits of civil aircraft.
