Description
Technical field
The utility model is related to a kind of aircraft maintenance device, more particularly, to a kind of aircraft maintenance jack.
Background technology
Main wheel jack is the special equipment that support top aircraft main unit of landing gear change main airplane wheel.The equipment
It is an innovative product, its innovation and application solve the problem for being not required to the full machine of support top aircraft just replaceable airplane wheel, carry
The high maintenance work efficiency of outfield undercarriage, has particularly significant meaning to the rate of attendance for improving aircraft.If to main wheel thousand
Jin top push rod is repaired and to supporting stand size redefinition, the equipment application can be made to carry out tearing open for wheel on polytype aircraft
Work is unloaded, therefore, this innovative technology has very big market value.
In the prior art, it is necessary to very heavy before the main jack of aircraft and aircraft particularly when dismounting nose-gear wheel
Topmast top aircraft, so its maintenance procedures is complicated, maintenance time is long, and maintenance cost is high, in addition, existing wheel jack volume
Greatly, weight weight, it has not been convenient to use, it is therefore necessary to improve.
Utility model content
1. the technical problem to be solved
Based on the above-mentioned problems in the prior art, the purpose of this utility model is that providing a kind of aircraft maintenance uses thousand
Jin top.
2. technical scheme
The purpose of this utility model is mainly realized by following technical scheme.
A kind of aircraft maintenance jack, it includes：Base, pressurized strut, fuel tank, hand pump, commutator, start cover；
Base, is placed on ground, for playing a supportive role；Pressurized strut, is fixedly mounted on the base by screw, is internally provided with
The telescopic piston rod of level Four, the pressurized strut top is provided with screw switch, during for controlling the piston rod to move up
Lift；Fuel tank, is placed on the base, for providing working solution to hand pump；Hand pump, passes through pipeline road and the liquid
Case connection is pressed oil, for when the piston rod is lifted and is declined, working solution to be supplied to the pressurized strut；Commutator, fixed peace
On base, inside sets and is provided with switch operation on reversal valve, the flow direction for controlling oil circuit working solution, the commutator
Bar, for determining that the piston rod rises or falls；Choke valve, is arranged on the pipeline road being connected with hand pump, the hand
The hydraulic oil for shaking pump outflow enters the pressurized strut along the choke valve.
Preferably, the pressurized strut has start cover, when jack when not in use, the pressurized strut cover buckle is in pressurized strut
Top.
Preferably, the base two ends respectively set leader, in order to carry.
3. beneficial effect
Compared with prior art, a kind of aircraft maintenance of the present utility model is with the beneficial effect of jack：
Jack is in use, the bottom that replacing wheel jack is placed on into airplane wheel is fixed, and adjustable change valve exists
Jack-up position, is moved back and forth with hand pump, aircraft fluid is squeezed into pressurized strut, jack-up frame；After reaching a certain height, adjust
Whole screw switch, makes pressurized strut be fixed on certain altitude constant；Wheel is changed, after the completion of replacing, adjustable change valve makes jack
It is slowly declined to be less than frame, removes jack wheel and change completion.
Aircraft maintenance of the present utility model jack small volume, is easy to carry；Working condition is full manual mode, operation
It is convenient；Equipment reliable operation is easy to maintenance；Loading capacity is big, safe and reliable；It is lightweight, conveniently moving；Fault rate is low.
