Abstract
A special tool for the ground sliding of a plane mainly comprises a hanging frame, idler wheels and a power device; the idler wheels and the power device are arranged on the hanging frame; the hanging frame can be fast mounted on a landing carriage of the plane; the idler wheels and plane tires are attached; when the power device drives the idler wheels to slide, the idler wheels can drive the plane tires to rotate in the opposite direction and push the plane.
Description
Technical field
The present invention relates to a kind of special tool that aircraft slides on the ground that promotes.
Background technology
At present, aircraft mainly contains two kinds in ground taxi mode: aero-engine promotes and trailer promotes.But promote to consume a large amount of Aviation Fuels by aero-engine, both uneconomical, also not environmental protection; And promote by trailer, although can solve to a certain extent the problem of economy and environmental protection, the weight of trailer is up to tens of ton, and itself is unusual oil consumption also, and in addition, because trailer is expensive and need dedicated driver, airport cannot be equipped with a large amount of trailers and driver.Therefore the mode that at present aircraft mainly takes aero-engine to promote in the time of ground taxi, only just can be used trailer to release in the stage of leaving aircraft gate, cause that airline company's fuel cost is high, pollute near airport day by day serious.Through investigation, airline company in the urgent need to a kind of cheap and simple, energy-conserving and environment-protective, do not need to change aircaft configuration, can promote the special tool that aircraft slides on the ground.But through retrieval, also there is no at present this type of special tool.
Summary of the invention
In order to overcome, aero-engine promotes and trailer promotes these two kinds of aircraft floors and slides the deficiencies such as the existing oil consumption of mode, costliness, not environmental protection, the invention provides and a kind ofly can slide special tool by Fast Installation aircraft floor aboard, can promote aircraft slides on the ground, economic environmental protection, aviator can remote manipulation, do not need a large amount of full-time operating personals, and cost is lower, is easy to be widely used.
The technical solution adopted in the present invention is: on hanger, roller and engine installation are installed, engine installation is connected with roller, hanger can be quick installed on undercarriage and make roller and aircraft tyre laminating, in the time that engine installation drives roller to rotate, roller drives aircraft tyre to rotate backward, and slides on the ground thereby promote aircraft.Engine installation comprises driving engine and change-speed box, and wherein driving engine can be both that genemotor can be also the driving engine such as fuel oil, combustion gas; Because the landing gear structure of various aircrafts is slightly had any different, therefore the structure of hanger is also thereupon different, as long as but can be fast dismounting make roller and aircraft tyre laminating on undercarriage.
The invention has the beneficial effects as follows, with engine installation and roller rotation aircraft tyre, promote aircraft and slide on the ground, simple in structure, cheap, economic environmental protection.Because roller diameter is less than aircraft tyre, therefore the mode of motion of roller promotion aircraft tyre is similar to " miniature gears drive big gear wheel ", can promote huge aircraft with less moment of torsion, gets twice the result with half the effort.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the constructional drawing of first embodiment of the present invention.
Fig. 2 is the constructional drawing of second embodiment of the present invention.
Fig. 3 is the constructional drawing of current aircraft nose-gear, is intended to be convenient to illustrate the specific embodiment of the present invention.
1. rollers in figure, 2. change-speed box, 3. driving engine, 4. storage battery, 5. hanger, 6. snap ring, 7. hook, 8. slide block, 9. jack, 101. undercarriage legs, 102. aircraft tyres, 103. trailer hangers.
Detailed description of the invention
In the embodiment shown in fig. 1, hanger (5) and subassembly snap ring (6) are hinged, angle between the two can regulate, roller (1), change-speed box (2), driving engine (3) is fixed on hanger (5), in the time that snap ring (6) is fixed on undercarriage leg (101), roller (1) is under the pressure of the self gravitation of this special tool, and aircraft tyre (102) laminating, driving engine (3) is fuel engines, the moment of torsion of its generation passes to roller (1) through change-speed box (2), roller (1) starts to rotate, can drive aircraft tyre (102) to rotate backward.
In embodiment illustrated in fig. 2, hanger (5) is slide rail, and its subassembly comprises hook (7), slide block (8) and jack (9).Roller (1), change-speed box (2), driving engine (3) and storage battery (4) are fixed on slide block (8), jack (9) is arranged on hanger (5), adopt the worm drive structure of screw rod and nut engagement, be used for promoting slide block (8) in the upper slip of hanger (5).To link up with (7) hang on alighting gear for hanging the trailer hanger (Fig. 3 103) of trailer, rotate jack (9), promote roller (1) and tire laminating on slide block (8), driving engine (3) is genemotor, under the driving of storage battery (4), produce moment of torsion, moment of torsion passes to roller (1) through change-speed box (2), and roller (1) starts to rotate, and can drive aircraft tyre to rotate backward.
Claims (4)
1. aircraft floor slides a special tool, and its feature comprises: hanger, roller and engine installation, and wherein roller and engine installation are arranged on hanger, and engine installation drives roller to rotate.
2. aircraft floor according to claim 1 slides special tool, it is characterized in that hanger can be quick installed on undercarriage.
3. aircraft floor according to claim 1 slides special tool, it is characterized in that roller leans on the power of the drive disk assembly generation on hanger or utilizes the self gravitation of this special tool to be pressed on aircraft tyre.
4. aircraft floor according to claim 1 slides special tool, it is characterized in that engine installation comprises driving engine and change-speed box, and the moment of torsion that driving engine produces passes to roller by change-speed box, and roller drives aircraft tyre to rotate backward.
