Problems solved by technology

[0004] The aviation hydraulic oil pump vehicle in the above patent is a self-propelled oil pump vehicle. When the hydraulic hose is still connected to the aircraft, if the person in the cab of the oil pump vehicle misuses and starts the oil pump vehicle away from the aircraft, the hydraulic hose will be stretched and After the hydraulic hose is pulled, the oil pump truck and the aircraft hydraulic system will continue to leak

Abstract

The invention discloses an aviation hydraulic oil pump vehicle with a coil pipe frame. The vehicle comprises a hydraulic hose in butt joint with an airplane hydraulic system, the hydraulic hose comprises a rear section, a middle section and a front section, a pair of electromagnetic valves are arranged at two ends of the middle section, the pair of electromagnetic valves are connected to an electric wire in series, and the pair of electromagnetic valves are normally-closed valves; and when a first hydraulic hose is stretched, the electric wire is snapped before the middle section of the hydraulic hose along with increase of tension, and the middle section of the hydraulic hose is snapped before the front section and the rear section of the hydraulic hose along with continuous increase of tension. After the hydraulic hose is snapped, continuous leakage of the oil pump vehicle and the airplane hydraulic system can be prevented.

Description

technical field [0001] The invention relates to the field of aircraft ground hydraulic energy protection equipment, in particular to an aviation hydraulic oil pump vehicle with a coil rack. Background technique [0002] Modern aircraft generally have a hydraulic system. When testing and maintaining the hydraulic system of the aircraft on the ground, ground oil pump equipment is needed to complete the performance testing of the aircraft hydraulic system. The aviation hydraulic oil pump truck is mainly designed to meet this requirement. of. [0003] The Chinese patent with the application number 201610672043.3 discloses an aviation hydraulic oil pump truck, which includes a high-pressure coil rack and a low-pressure coil rack. , The oil outlet is docked; the hydraulic hose on the high-pressure coil rack delivers hydraulic oil to the oil inlet of the aircraft hydraulic system; the hydraulic hose on the low-pressure coil rack absorbs oil from the oil outlet of the aircraft hydr...
