Problems solved by technology

[0002] In the civil aviation airport's hydraulic maintenance field where the aircraft reverse thrust cover is opened during maintenance of the engine, the existing hydraulic actuation system is originally equipped with an electric cylinder manual booster method, which requires manual operation. , and the pressurization speed is slow, there is no oil filter, and it cannot meet the needs of modern use. Therefore, a system to replace the manual manual hydraulic pressurization device to open the aircraft thrust reverser cover is studied.

Abstract

The invention discloses a hydraulic actuation system and relates to the technical field of hydraulic control equipment. A universal wheel and two direction wheels are arranged at the bottom of a vehicle body; a side door is arranged on the front side of the vehicle body; an upper closing cover is arranged at the upper part of the vehicle body; the rear side of the vehicle body is connected with a push-pull rod; a control panel is arranged in the vehicle body and is in control connection with an electric control system; a hydraulic system is arranged in the vehicle body. The hydraulic actuation system has the advantages of reasonable structure design, easier operation and high degree of modernization; by adopting electricity to replace manual hand cranking for hydraulic boosting opening, the human and material resources are saved, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a hydraulic actuation system, in particular to a hydraulic maintenance system for opening an aircraft reverse thrust cover during engine maintenance in civil aviation airports. Background technique [0002] In the civil aviation airport's hydraulic maintenance field where the aircraft reverse thrust cover is opened during maintenance of the engine, the existing hydraulic actuation system is originally equipped with an electric cylinder manual booster method, which requires manual operation. , and the pressurization speed is slow, there is no oil filter, and it cannot meet the needs of modern use. Therefore, a system to replace the manual manual hydraulic pressurization device to open the aircraft thrust reverser cover is studied. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic actuation system to solve the problems in the above-mentioned background technology. [0004] In ord...
