Abstract

The utility model belongs to the technical field of hydraulic control of an aircraft, and relates to a retracting mechanism of an aircraft cargo door for providing hydraulic energy for an aircraft cargo door system. A hydraulic oil tank of the retracting mechanism is connected with one end of a self sealing valve and an electric pump; the other end of the electric pump is connected with one end of a one-way valve; the other end of the one-way valve is connected with the self sealing valve and simultaneously is connected with a pressure switch, a pressure adjusting valve and a throttle valve by an oil filter; and two paths of outlets of the cargo door retracting electromagnetic valve are respectively connected with cargo door retracting actuator cylinder and a speed-regulating valve. The retracting mechanism integrates power elements and actuator elements, conducts hydraulic control on a mechanical control part of the original cargo door, effectively combines a hydraulic system and the mechanical actuator together, and changes mechanical manual operation into automatic operation so as to meet the requirement of reliable and stable retracting of an aircraft on a cargo door, especially a large cargo door on the ground.

Description

The airplane cargo doors jack
Technical field
The utility model belongs to the aircraft technical field of hydraulic, relates to a kind of airplane cargo doors jack that hydraulic energy source is provided for the aircraft hold door system.
Background technology
The folding and unfolding of airplane cargo doors is the important additional function that aircraft is carried out on ground.Existing airplane cargo doors extension and retraction system is the armstrong's patent formula, its version is typical hinge-type, or passive delivery strut manual support, utilize the aircraft of this mechanism can only realize the manually cargo door folding and unfolding of control, action is required great effort and can only be applied to small-sized mechanism.
Summary of the invention
The purpose of this utility model is: a kind of airplane cargo doors automatic deploying and retracting system that is used for is provided, with satisfy aircraft on ground in the face of cargo door especially large cargo hold door carries out reliably, the airplane cargo doors jack of pulsation-free folding and unfolding requirement.
The technical solution of the utility model is: jack comprises hydraulic reservoir, self-styled valve, pressure switch, motor-drive pump, check valve, self-styled valve, the oil filter, pressure regulating valve, governor valve, flow regulating valve, cargo door folding and unfolding electromagnetic valve, cargo door folding and unfolding pressurized strut, one end of hydraulic reservoir and self-styled valve and motor-drive pump joins, one end of the other end of motor-drive pump and check valve joins, the other end of check valve and self-styled valve join, simultaneously by oil filter and pressure switch, pressure regulating valve, flow regulating valve and cargo door folding and unfolding electromagnetic valve join, and the two-way outlet of cargo door folding and unfolding electromagnetic valve joins with cargo door folding and unfolding pressurized strut and governor valve respectively.
The utility model has the advantages that: the utility model integrates dynamical element and power element, the mechanical control of original cargo door part is replaced by fluid control, and hydraulic efficiency pressure system and mechanical operating part combined effectively, it is manually automatic for hydraulic pressure to become machinery, with satisfy aircraft face on ground cargo door especially the large cargo hold door carry out reliably, pulsation-free folding and unfolding requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1, jack comprises. hydraulic reservoir 1, self-styled valve 2, pressure switch 3, motor-drive pump 4, check valve 5, self-styled valve 6, oil filter 7, pressure regulating valve 8, governor valve 9, flow regulating valve 10, cargo door folding and unfolding electromagnetic valve 11, cargo door folding and unfolding pressurized strut 12, hydraulic reservoir 1 joins with an end of self-styled valve 2 and motor-drive pump 4, one end of the other end of motor-drive pump 4 and check valve 5 joins, the other end of check valve 5 and self-styled valve 6 join, simultaneously by oil filter 7 and pressure switch 3, pressure regulating valve 8, flow regulating valve 10 and cargo door folding and unfolding electromagnetic valve 11 join, and the two-way outlet of cargo door folding and unfolding electromagnetic valve 11 joins with cargo door folding and unfolding pressurized strut 12 and governor valve 9 respectively.
Working process of the present utility model is: when putting cargo door, cargo door folding and unfolding master cock is placed the position of putting, this moment, motor-drive pump 4 was started working, cargo door folding and unfolding electromagnetic valve 11 energising conversions simultaneously, and pressure oil is by governor valve 9 and the upper epicoele that flows to cargo door folding and unfolding pressurized strut 12 of electromagnetic valve.System pressure is unblanked pressurized strut, promotes cargo door simultaneously and puts down, when cargo door puts down fully, and when locking, motor-drive pump 4 and 11 outages of cargo door folding and unfolding electromagnetic valve, folding and unfolding electromagnetic valve 11 is returned to midway location, system unloaded is connected in cargo door folding and unfolding pressurized strut two-chamber while and oil return.
When receiving hatch door, cargo door folding and unfolding master cock is placed the position of receipts, this moment, motor-drive pump 4 was started working, cargo door folding and unfolding electromagnetic valve 11 energising conversions simultaneously, and pressure oil is by the electromagnetic valve 11 the next cavity of resorptions that flow to cargo door folding and unfolding pressurized strut.System pressure is unblanked pressurized strut 12, promotes cargo door simultaneously and packs up, when cargo door is packed up fully, and when locking, emergent motor-drive pump and the outage of cargo door folding and unfolding electromagnetic valve, the folding and unfolding electromagnetic valve is returned to midway location, system unloaded is connected in cargo door folding and unfolding pressurized strut two-chamber while and oil return.
