Aircraft ground hydraulic oil pump vehicle with quick-change connectors

Abstract

The invention discloses an aircraft ground hydraulic oil pump vehicle with quick-change connectors. A high-pressure oil outlet pipeline of the aircraft ground hydraulic oil pump vehicle is connected with an oil outlet transitional pipe through a first quick-change connector on an oil outlet side, and the oil outlet transitional pipe is connected with an oil outlet flexible pipe through a second quick-change connector on the oil outlet side. A low-pressure oil return pipeline of the aircraft ground hydraulic oil pump vehicle is connected with an oil return transitional pipe through a first quick-change connector on an oil return side, and the oil return transitional pipe is connected with an oil return flexible pipe through a second quick-change connector on the oil return side. According to the aircraft ground hydraulic oil pump vehicle, the oil outlet flexible pipe and the oil return flexible pipe are prevented from breaking by pulling, and the oil pump vehicle and an aircraft hydraulic system are prevented from continuously leaking after the oil outlet transitional pipe and the oil return transitional pipe are broken by pulling; and the quick-change connectors are adopted to connect the oil outlet transitional pipe and the oil return transitional pipe, and the oil outlet transitional pipe and the oil return transitional pipe which are broken by pulling are convenient to quickly change.

Description

technical field [0001] The invention relates to the field of aircraft ground hydraulic energy protection equipment, in particular to an aircraft ground hydraulic oil pump vehicle with quick-change joints. Background technique [0002] When testing and maintaining the hydraulic system of the aircraft on the ground, it is necessary to perform performance testing on the hydraulic system of the aircraft through the hydraulic oil pump truck on the ground of the aircraft. [0003] The aircraft ground hydraulic oil pump truck generally includes a high-pressure oil outlet pipeline, an oil outlet hose, a low-pressure oil return pipeline and an oil return hose; The hose is pulled out to the outside of the oil pump truck and docked with the oil outlet of the aircraft hydraulic system; the high-pressure oil outlet line is connected to the oil outlet hose, and the high-pressure oil outlet line delivers hydraulic oil to the oil inlet of the aircraft hydraulic system through the oil outlet...

AI Technical Summary

Problems solved by technology

[0004] Aircraft ground hydraulic oil pump trucks are generally self-propelled oil pump trucks. When the oil outlet hose and oil return hose are still connected to the aircraft, if the person in the cab of the oil pump truck misoperates and starts the oil pump truck away from the aircraft, the oil outlet will be soft. Pipes and / or return hoses can be stretched and snapped, pump trucks and aircraft hydraulic systems will continue to leak after the outlet and / or return hoses are pulled
