Control system of aeroengine mounting vehicle

Abstract

The invention discloses a control system of an aeroengine mounting vehicle, which comprises a PLC (programmable logic controller), an operation screen, an electro-hydraulic servo amplifier group, a hydraulic system and a built-in displacement sensor group, wherein the hydraulic system comprises an electro-hydraulic servo valve group, a hydraulic source, a pipeline system and a hydraulic oil cylinder group, the electro-hydraulic servo valve group is arranged in the pipeline system for connecting the hydraulic source with the hydraulic oil cylinder group, the operation screen is connected with the PLC through a bus, a control signal outputted by the PLC is amplified by the electro-hydraulic servo amplifier group and then connected with the electro-hydraulic servo valve group, the hydraulic oil cylinder group is equipped with a safety shutoff valve group, the displacement sensor group is arranged in the hydraulic oil cylinder group, and the output of the displacement sensor group is connected with the PLC. The control system has the beneficial effects of realizing six-degree-of-freedom precise control of main lifting, horizontal rotation, front and back movement, left and right movement, back end pitching, lateral rotation, front-end pitching, and up and down movement of the aeroengine mounting vehicle and has the advantages of high control precision, high degree of automation and the like.

Description

technical field [0001] The invention relates to an automatic control system, in particular to a control system for an aero-engine installation vehicle. Background technique [0002] Most of the existing aero-engine installation and disassembly is done in a dedicated work shed. First, the aircraft that needs to be loaded and unloaded must be driven into the work shed, and then the aero-engine installation is completed manually or using some simple installation and support devices. loading and unloading. The shortcomings of this loading and unloading method are mainly manifested in: (1) a special work shed is required, and the cost of engine loading and unloading is very high; (2) because the aircraft needs to be moved to the work shed to carry out loading and unloading operations, the mobility is very poor; (3) automation The degree is not high and the efficiency is low. Therefore, there is a need for a device and its control system that can realize the engine loading and u...
