Description
Technical Field
The utility model relates to an airport boarding equipment field says in detail to a carbon-fibre composite military airstairs.
Background
It is well known that at military airports, ground crew or pilots use high frequencies of airstairs for maintenance or for entering and exiting the cockpit to perform flight tasks. The existing airstairs are mostly of metal structures, the problems of heaviness, poor use comfort, easy corrosion, large transition weight and the like generally exist, and in addition, the airstairs cannot be disassembled and assembled and have poor stability.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a for military use airstair of carbon-fibre composite, light in weight, rigidity are better, and stability is high, prevents to bruise or rub aircraft coating, easy dismounting.
The utility model provides a technical scheme that its technical problem adopted is: a military airstair made of carbon fiber composite material is provided with a frame type ladder frame and is characterized in that rollers are arranged at the bottom of the ladder frame, two sides of the top of the ladder frame are respectively provided with a bent arm through a connecting sleeve, a lateral anti-abrasion gasket is fixed at the lateral part of the ladder frame at the lower part of the connecting sleeve, the other end of the bent arm is provided with a hook, a handrail is fixed in the vertical direction at the upper part of one bent arm, a frame beam pedal is connected between the two bent arms, a guide pin is fixed on the lower side surface of the frame beam pedal, two sides of the upper part of the ladder frame are respectively hinged with the upper end of an upper supporting rod, two sides of the lower part of the ladder frame are respectively hinged with the upper end of a lower supporting rod, the lower ends of the upper supporting rod are hinged with the lower ends of the lower supporting rods, the lower ends of the, the lower supporting rod, the connecting sleeve, the handrail and the bent arm are made of carbon fiber composite materials.
The beneficial effects of the utility model are that, light in weight, rigidity are better, and stability is high, prevents to bruise or rub aircraft coating, easy dismounting.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, an armrest, 2, a frame beam pedal, 3, a hook, 4, a guide pin, 5, an anti-abrasion gasket, 6, a connecting rod, 7, an upper supporting rod, 8, a lower supporting rod, 9, a roller, 10, a ladder frame, 11, a side anti-abrasion gasket, 12, a connecting sleeve and 13, a bent arm are arranged.
Detailed Description
In the figure, the utility model discloses be equipped with frame-type ladder frame 10, gyro wheel 9 is installed to the bottom of ladder frame 10, a curved boom 13 is installed respectively through adapter sleeve 12 in the top both sides of ladder frame 10, ladder frame 10 lateral part of adapter sleeve 12 lower part is fixed with side abrasionproof gasket 11, couple 3 is installed to the curved boom 13 other end, be fixed with a handrail 1 in the upper portion vertical direction of a curved boom 13, be connected with frame roof beam footboard 2 between two curved booms, be fixed with a guide pin 4 on the downside of frame roof beam footboard 2, ladder frame 10 upper portion both sides are articulated with the upper end of an upper strut 7 respectively, ladder frame 10 lower part both sides are articulated with the upper end of a lower strut 8 respectively, the lower extreme of upper strut 7 is articulated with the lower extreme of lower strut 8, the lower extreme of two lower struts in the left and right sides is fixed together through connecting rod 6, connecting rod 6 both ends are
The utility model discloses frame roof beam footboard 2, connecting rod 6, go up support bar 7, lower support bar 8, adapter sleeve 12, handrail 1 and curved boom 13 adopt carbon-fibre composite to make, and connecting piece between the detachable part passes through metal working and bolted connection, and the aircraft of colliding with is avoided to the equal cladding rubber class material in top layer of aircraft contact element. The ladder frame 10 and the bent arm 13 are respectively subjected to compression molding, secondary curing is performed after secondary reinforcing wrapping to obtain an integral structure, and the integral structure is reinforced through the connecting sleeve 12, so that the integral strength of the airstairs is higher, the rigidity is better, and the stability of the airstairs is effectively enhanced. The hook 3 is hung on an airplane window frame, and the contact part of the hook and the airplane is coated by rubber materials to prevent the collision or friction of an airplane coating. The frame beam pedal 2 is a composite material die-formed part and mainly abuts against a cabin door frame beam to prevent the frame beam of the airplane from being trampled in and out, a rubber material is coated on a contact part of the frame beam of the cabin door to prevent the frame beam of the airplane from being damaged or rubbed by the airplane, a guide pin 4 is pre-buried and fixed on the frame beam pedal 2 during forming, a reserved hole of an airplane body is inserted to play a role in guiding and positioning when the airplane boarding ladder is hung, the handrail 1 is used for supporting when the airplane enters and exits the rear cabin, the handrail 1 is a composite material structural member, the rubber material is coated on the end of the handrail 1 to prevent the boarding ladder from being worn, the wear-resistant gasket 5 and the side wear-resistant gasket 11 are mainly used for preventing the ladder body of the composite material from being directly contacted with the ground to generate wear during transportation and parking, and the idler wheel.
