Detailed Description
The invention provides a device for guiding a suspension cable of a side-mounted nacelle of an aircraft, which is explained below with reference to the accompanying drawings.
Referring to fig. 1 to 4, the suspension cable guide apparatus of the present invention is mainly composed of an upper guide wheel 13, an upper guide wheel support 12, a lower guide wheel 6, a lower guide wheel support 8, and a plurality of stub shafts. Wherein the content of the first and second substances,
When the suspension cable guide device is assembled, an upper guide wheel 13 is firstly arranged on an upper guide wheel bracket 12 through a bolt shaft, and a lower guide wheel 6 is arranged on a lower guide wheel bracket 8 through a bolt shaft; then the first flat head shaft 5, the second flat head shaft 11, the third flat head shaft 10 and the fourth flat head shaft 9 are respectively arranged at the appointed mounting holes on the upper guide wheel bracket 12 and the lower guide wheel bracket 8; and finally, fixing the upper and lower guide wheel brackets together through bolts. During installation, the rotation of the upper guide wheel 13 and the lower guide wheel 6 should be checked to confirm that they can rotate flexibly.
When the suspension cable guide device is installed on the airplane, the suspension cable guide device 3 is firstly fixed on the nacelle hanging platform 4 through bolts, then the suspension cable 2 penetrating out from the upper opening of the airplane body 1 penetrates through the groove of the upper guide wheel 13, penetrates through the lower guide wheel support 8 after passing through the openings of the upper guide wheel support 12 and the lower guide wheel support 8, and finally the suspension cable 2 is connected with the nacelle.
When the nacelle is retracted, the suspension cable 2 moves in the grooves of the upper guide wheel 13 and the lower guide wheel 6. The first stub shaft 5 is provided to prevent the hoist cable 2 from coming out of the groove of the upper guide wheel 13, and the hoist cable after coming out may be clamped into the gap between the upper guide wheel 13 and the upper guide wheel bracket 12 or be stuck outside the upper guide wheel bracket 12, which may cause the nacelle to be unable to be retracted and cause serious flight accidents. The second stub shaft 11 is provided to limit the swing angle of the hoist cable 2 at the opening of the upper guide wheel bracket 12 and the lower guide wheel bracket 8, and to prevent the hoist cable 2 from being scraped against the edge of the opening. The third horizontal shaft 10 is provided to prevent the suspension cable 2 from coming out of the groove of the lower guide wheel 6, and the suspension cable after coming out may be clamped into the gap between the lower guide wheel 6 and the lower guide wheel bracket 8, which may cause the nacelle to be unable to be retracted, thereby causing a serious flight accident. The fourth flat head shaft 9 is arranged for preventing the suspension cable 2 from falling out of the groove of the lower guide wheel 6, and the suspension cable after falling out is possibly clamped outside the lower guide wheel bracket 8, so that the nacelle cannot be retracted and serious flight accidents are caused; meanwhile, the fourth flat head shaft 9 can prevent the hanging cable 2 from scraping the edge of the lower guide wheel bracket 8 when swinging along the heading direction. When the nacelle deflects, the suspension cable 2 can be ensured not to be scraped with the rim of the lower guide wheel 6 through the limit of the second flat head shaft 11 and the width of the groove of the lower guide wheel 6.
The invention consists of two groups of guide wheels, two groups of guide wheel brackets and a plurality of flat head shafts.
Illustratively, the two sets of guide wheels are machined from a 7050 aluminum plate, the upper guide wheel 13 being used to direct the cables extending laterally from the fuselage in a vertically downward direction, and the lower guide wheel 6 being used to direct the vertically downward cables in a counter-heading direction when the nacelle is lowered. And the two groups of guide wheels are provided with grooves for guiding the movement of the hoisting cable. The size of the groove of the upper guide wheel is slightly larger than the diameter of the hanging cable, so that the path of the hanging cable extending out of the machine body is limited, and the phenomenon that the hanging cable is scratched with an opening of the machine body due to overlarge swing range is avoided. The size of the groove of the lower guide wheel is larger, the maximum swing angle range of the suspension cable after the suspension cable is turned through the groove is calculated during design and is larger than the maximum swing angle range, and the problem that the outer skin of the suspension cable is abraded or a lead inside the suspension cable is damaged due to the fact that the suspension cable is interfered with the rim of the guide wheel when the suspension cable goes out of the groove is avoided. Ball bearings are arranged at the rotating shafts of the two guide wheels and used for ensuring that the guide wheels can flexibly rotate. In addition, the diameter of the two guide wheels is larger, so that the hoisting cable can have a larger bending radius when passing through, and the fatigue fracture of the wire in the hoisting cable is avoided. The diameter can be in the range of 100-140mm, for example, 120 mm. Optionally, the diameter of the guide wheel is determined according to the material, size and the like of the hoist cable.
The two groups of guide wheel brackets are also manufactured by a 7050 aluminum plate machine and are respectively used for providing support for the two groups of guide wheels. The steel bushing is embedded in the mounting position of the guide wheel support and the guide wheel rotating shaft, so that the steel rotating shaft is prevented from wearing a mounting hole in the aluminum support, and the situation that the mounting hole in the aluminum support is deformed due to overlarge stress of the suspension cable can be prevented.
A plurality of flat head shafts are arranged on the two guide wheel supports and used for limiting the suspension cable, ensuring that the suspension cable cannot be separated from the guide wheels and avoiding scraping of parts such as the support and the like due to overlarge swing angle of the suspension cable. The plain end shaft is manufactured by a machining process using a common steel bar.
The invention realizes the design of the suspension cable guide device suitable for the side-mounted nacelle of the airplane, the guide device is flexible to rotate, the suspension cable can be effectively prevented from falling off, and the suspension cable can be sufficiently protected.
The invention relates to a suspension cable guide device which is suitable for a side-mounted nacelle of an airplane. The main materials of all parts of the device are aviation aluminum plates and common steel bars, the machining mode is machining, the process method is mature, and the device is easy to manufacture. The invention can provide enough protection for the movement of the suspension cable through the arrangement of the flat head shafts at a plurality of positions, and prevent the suspension cable from falling off to cause flight accidents or being scratched with other parts to cause the damage of the suspension cable. The guide wheel of the device is large in diameter, and fatigue fracture of the lead in the suspension cable can be prevented. Through setting up ball bearing and steel bush, can guarantee that the leading wheel rotates in a flexible way, make the suspension cable receive and release the steady no jamming of operation.
