Abstract
The present invention relates to a kind of aircraft floor to maintain equipment technical fields, more particularly, to a kind of airplane wheel cooling device and cooling means.Wheel cooling device used by aircraft is water cooling and borrows the cooling two ways of air-conditioned coach at present, and such cooling device can be realized cooling effect, but efficiency is lower.In order to solve the above-mentioned technical problem, the present invention airplane wheel cooling device cooling using a kind of dispersion of multi-point, the device includes the pairs of terminal pad being capable of fixing on the outside of wheel hub, and each terminal pad is connected to cooling gas source, and has several air nozzles towards wheel hub.In the case where guaranteeing that cooling gas source is constant, airplane wheel cooling efficiency is improved.
Description
Technical field
The present invention relates to a kind of aircraft floor to maintain equipment technical fields, more particularly, to a kind of airplane wheel cooling device
And cooling means.
Background technique
Clear stipulaties in aircraft maintenance handbook: after brake main wheel brakes under the conditions of normally landing, attack time again
It must not be less than 30min, if aircraft 30min domestic demand is set out again, or exceeding normal landing weight, normally landing brake speed
Or ground continuously slides after braking and needs to set out again, if temperature is more than permissible value (or Hot melt plug melts), it is necessary to immediately
It is cooling (allowing water cooling) to carry out artificial pressure；Aircraft is after stopping to take off stopping or ground continuously slides brake (15~25) min
Stop, if temperature is more than permissible value (or Hot melt plug melts), it is necessary to it is cooling (allowing water cooling) to carry out artificial pressure immediately.
Wheel cooling device used by aircraft is water cooling and the cooling two ways of borrow air-conditioned coach, such cooling dress at present
It sets and can be realized cooling effect, but efficiency is lower.
Summary of the invention
The present invention overcomes deficiencies in the prior art, have redesigned airplane wheel cooling means, are guaranteeing that wheel is cold
But under the premise of function, a kind of wheel cooling means efficiently, synchronous is provided, to solve above-mentioned to be unsatisfactory for situation.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of airplane wheel is cooling
Device, for being cooled down on ground in face of wheel, which includes the pairs of terminal pad being capable of fixing on the outside of wheel hub,
Each terminal pad is connected to cooling gas source, and has several air nozzles towards wheel hub.
Terminal pad is uniformly connected on transfer panel by branch pipeline, and transfer panel is connected to by hose with cooling gas source.
The hose has the adapter connecting with cooling gas source.
There is link and hook in relative position in each terminal pad, be connected with each other locking after holding wheel hub tightly.
There are 9 air nozzles in each terminal pad.
The cooling gas source is provided by nitrogen cylinder or nitrogen vehicle.
Length is arranged in the hose according to actual needs.
A method of airplane wheel is carried out using above-mentioned cooling device it is cooling, after wheel overtemperature, by pairs of company
It connects disk and is mounted on wheel hub two sides, open cooling gas source, comprehensive synchronous cooling is carried out to wheel hub and brake system.
The utility model has the advantages that compared with prior art, the invention has the advantages that the aircraft machine cooling using a kind of dispersion of multi-point
Cooling device is taken turns, in the case where guaranteeing that cooling gas source is constant, improves airplane wheel cooling efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of aircraft cooling device of the present invention；
Fig. 2 is the hanging structure schematic diagram of terminal pad.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing: a kind of cooling dress of airplane wheel
It sets, the concrete form of which is as shown in Figure 1, cooling source is provided by nitrogen cylinder or nitrogen vehicle, and the device mainly includes adapters
1, hose 2, transfer panel 3, branch pipeline 4 and terminal pad 5, wherein adapter 1 is connect with gas source, 2 connecting adapter 1 of hose and switching
Gas source in hose 2 is converted 4 tunnels, i.e. branch pipeline 401, branch pipeline 402, branch pipeline 403, branch pipeline 404 by disk 3, transfer panel 3,
Branch pipeline 401, branch pipeline 402, branch pipeline 403, branch pipeline 404 respectively with terminal pad 501, terminal pad 502, terminal pad 503, even
Connect the connection of disk 504.Be illustrated by taking terminal pad 501 as an example, as shown in Fig. 2, terminal pad 501 relative position have link 601,
602 and hook 701,702.Terminal pad 501 is stuck on the outside of wheel hub when use, and by opposite hook 701 and link 601
It is connected after holding wheel hub tightly, is connected after holding opposite hook 702 tightly wheel hub with link 602, be allowed to quickly connect with wheel.Connection
There are 9 air nozzles 801 on disk 501, nitrogen dispersion can be sprayed, after wheel overtemperature, connection can be fast implemented winged by this method
It is cooling while machine wheel, improve Support efficiency.
In one embodiment of the present of invention, the air nozzle 801 in terminal pad 501,502,503,504 can suitably increase, or
Air nozzle 801 is changed the outfit as misty air nozzle, terminal pad quantity also can reach cooling effect by actual use quantity configuration.
