Abstract
The utility model belongs to the experimental field of aircraft flight technique, concretely relates to a slide rail type bracket for installing APU. Installation APU power device is structural in the primary load bearing in APU cabin, receive APU cabin structure space limitation (APU cabin after -opening, it is narrow and small to control the space), the construction and installation difficulty, in order to guarantee the APU power device installation, a slide rail type bracket for installing APU device has been designed, it is stretched cantilever structure by cable suspension device after with and constitutes, compact structure, the handiness, simple maintenance, the production cost is low, economy and practicality, the repacking of APU driving system structure is correct reliable, APU is in proper working order.
Description
Technical field
The utility model belongs to aviation flight test art, is specifically related to a kind of slide rail type bracket for installing APU.
Background technology
For completing certain by the carrier aircraft proving flight of test system, selecting fortune eight aircraft to be carrier aircraft, installing the task systems such as power supply, liquid cooling, control additional, by taking a flight test under Real Atmosphere condition, verify by the radical function of test system and performance.Due to by test system electricity consumption up to 70KW, former machine dump energy can not meet the demands, and needs in carrier aircraft, install APU power system additional, is with set generator to provide the electromotive power output of three-phase alternating current 90KW by APU.
After repacking fortune eight aircraft, deck store is APU cabin, and design vibration damping combination leverage, installs APU engine installation on the main force support structure in APU cabin.APU weight 160Kg; stopped status height off the ground about 7 ~ 8 meters after installing, by APU cabin structure space constraint (APU cabin after-opening, left and right narrow space), installation difficulty; in order to ensure that APU engine installation is installed, devise the slide rail type bracket system for installing APU.
Utility model content
A kind of slide rail type bracket for installing APU is provided, by erecting by overhang and after stretch cantilever beam structure and form.
Erecting by overhang is made up of slide track component, suspension ring framework, main regulation screw arbor assembly, auxiliary adjustment screw arbor assembly and Connection Block.Slide track component is combined by roller and channel; Suspension ring framework is welded by channel-section steel and suspension ring; Main regulation screw arbor assembly adopts Tr30 × 4 Acme thread, and good manufacturability, root of the tooth intensity are high, is suitable for lifting and lifting mechanism; Auxiliary adjustment screw arbor assembly adopts M10 STRTHD, is used for regulating the installation elevation angle of APU.
After stretch cantilever beam structure and be made up of digonal link, I-shape longitudinal and cross beam, deck store architrave is connected with crossbeam by angle box; Crossbeam fixedly mounts two I-shaped aluminium section bars as longeron.
Slide rail type carrier structure for installing APU is compact, control comfort, safeguards simple, low cost of manufacture, economical and practical, and the repacking of APU power system architecture is correct reliable, and APU is working properly.

Detailed description of the invention
Composition graphs 1-4, the slide rail type bracket for installing APU of the present utility model, by erecting by overhang and after stretch cantilever beam structure and form.
Erecting by overhang is made up of slide track component 1, suspension ring framework 2, main regulation screw arbor assembly 3, auxiliary adjustment screw arbor assembly 4 and Connection Block 5.Slide track component 1 is combined by roller and channel; Suspension ring framework 2 is welded by channel-section steel and suspension ring; Main regulation screw arbor assembly 3 adopts Tr30 × 4 Acme thread, and good manufacturability, root of the tooth intensity are high, is suitable for lifting and lifting mechanism; Auxiliary adjustment screw arbor assembly 4 adopts M10 STRTHD, is used for regulating the installation elevation angle of APU.
After stretch cantilever beam structure and be made up of digonal link 7, I-shape longeron 8 and crossbeam, deck store architrave is connected with crossbeam by angle box; Crossbeam fixedly mounts two I-shaped aluminium section bars as longeron 8.
When APU body 9 is installed, first on longeron, slide track component is installed, then with crane sling lower extension APU erecting by overhang, put erecting by overhang on slide rail, pass erecting by overhang, APU body 9 enters APU cabin 6, installs APU body 9 after regulating erecting by overhang to make APU body 9 be in correct installation site with vibration damping combination pull bar.
Below the operation of the utility model slide rail type bracket is described further:
(1) basic design that APU engine installation vibration damping combination leverage connects is reequiped;
(2) 3 crossbeams are installed;
(3) cantilever beam structure is stretched after installing;
(4) slide rail type bracket is connected with APU body 9 mount pad, lifting APU engine installation;
(5) with crane, APU9 is winched to setting height(from bottom), stretch on the slide rail of cantilever beam structure, APU body 9 is advanced APU cabin 6 after being mounted on by slide rail type bracket, adjustment APU body 9 position is locked with stop screw after putting and putting in place.Again crane hook is departed from suspension ring;
(6) install left support abutment, switching angle box and the right side, rear two groups regulate leverages, by three of APU install nodes be connected with damping, buffering bearing, adjusting yoke length, is adjusted to predeterminated position by APU body 9;
(7) slide rail cantilever beam structure is stretched after removing.
Claims (1)
1., for installing a slide rail type bracket of APU, it is characterized in that: by erecting by overhang and after stretch cantilever beam structure and form;
Described erecting by overhang is made up of slide track component (1), suspension ring framework (2), main regulation screw arbor assembly (3), auxiliary adjustment screw arbor assembly (4) and Connection Block (5); Slide track component (1) is combined by roller and channel; Suspension ring framework (2) is welded by channel-section steel and suspension ring; Main regulation screw arbor assembly (3) adopts Tr30 × 4 Acme thread; Auxiliary adjustment screw arbor assembly (4) adopts M10 STRTHD, is used for regulating the installation elevation angle of APU;
After stretch cantilever beam structure and be made up of digonal link (7), I-shape longeron (8) and crossbeam, deck store architrave is connected with crossbeam by angle box; Crossbeam fixedly mounts two I-shaped aluminium section bars as longeron (8).
