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

Abstract

The invention discloses an aircraft ground hydraulic oil pump truck with quick-change joints. The joint is connected with the oil outlet hose; the low pressure oil return pipeline is connected with the oil return transition pipe through the first quick-change joint on the oil return side, and the oil return transition pipe is connected with the oil return hose through the second quick-change joint on the oil return side. The invention can prevent the oil outlet hose and the oil return hose from being pulled off, and can prevent the oil pump truck and the aircraft hydraulic system from continuously leaking after the oil outlet transition pipe and the oil return transition pipe are pulled off; The oil outlet transition pipe and the oil return transition pipe can be easily and quickly replaced the broken oil outlet transition pipe and oil return transition pipe.

Description

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