[0001] This application belongs to the technical field of aircraft structural design, and particularly relates to a single aircraft floor beam with both a fixed mooring seat and a mooring rail interface. Background Art
[0002] During the process of transporting goods in the aircraft cargo hold, it is necessary to moor and limit the goods. Therefore, mooring interfaces need to be set on the cargo hold floor and used in conjunction with mooring equipment such as mooring ropes, i.e., mooring chains and mooring straps.
[0003] The mooring of the existing aircraft cargo hold floor is generally divided into two types: fixed mooring and detachable mooring. The connection method of the fixed mooring interface is as follows: directly machining a fixed mooring pile on the aircraft floor longitudinal beam, and fixing the mooring ring or mooring post of the aircraft to the mooring pile through bolts. When in use, the mooring rope is connected to the card slot of the mooring ring or mooring post, etc. The connection method of the detachable mooring interface is as follows: setting a mooring rail on the aircraft floor to replace the floor longitudinal beam, and installing a detachable mooring ring at any interface of the mooring rail according to the needs of the cargo mooring position.
[0004] Both the fixed mooring and detachable mooring of the existing aircraft occupy separate floor longitudinal beam tracks, resulting in limited connection points for mooring ropes when the aircraft transports large goods or vehicles, and the mooring plan is not flexible enough.

The implementation modes of this application will be described in detail below in conjunction with the accompanying drawings.
[0024] This application provides a single aircraft floor beam with both a fixed mooring seat and a mooring slide rail interface, as Figure 1 - Figure 2 shown, the floor beam 1 includes a fixed mooring ring interface 2 and a mooring slide rail interface 3;
[0025] The fixed mooring ring interface 2 has a nest-shaped receiving groove, in which a mooring ring assembly is fixed. The mooring ring assembly includes a support 4 and a fixed mooring ring 5. The fixed mooring ring 5 can rotate around the rotating shaft of the support 4 so that the fixed mooring ring 5 sinks into the nest-shaped receiving groove or protrudes from the upper surface of the floor;
[0026] The mooring slide rail interface 3 has a strip-shaped groove for receiving and installing a strip-shaped mooring slide rail 8. The mooring slide rail 8 is formed with a plurality of mounting hole interfaces 81 along the extending direction of the notch of the strip-shaped groove for installing a detachable mooring ring 7.
[0027] This application realizes the fixation of goods through the fixed mooring ring interface 2 and the mooring slide rail interface 3. Among them, the fixed point mooring ring interface 11 is connected to the mooring ring assembly. The mooring slide rail interface 3 is connected to the mooring slide rail 8. The mooring slide rail 8 has strong versatility and flexibility. Each mooring slide rail has a plurality of mounting hole interfaces 81 and can be flexibly used according to the position requirements of the mooring points to realize variable point mooring within the range of the mooring slide rail. In addition, in addition to being used as an installation interface for detachable mooring rings, the mooring slide rail 8 can also be used as an installation interface for seats, pallets, stretcher stations, medical workbenches and other various product equipment and brackets.
[0028] Refer to Figure 2, the mooring ring assembly of the present application can rotate around the rotating shaft of the support 4. According to whether it is used for cargo mooring, the mooring ring has two states: when used for mooring, the mooring ring has a flipped-up state M, which is higher than the upper surface of the floor and can rotate 0-180 degrees around the rotating shaft of the support. When not in use, the mooring ring has a retracted state N. At this time, the mooring ring sinks into the nest-shaped receiving groove and does not protrude above the upper surface of the floor.
[0029] In some alternative embodiments, the floor beam 1 is integrally machined from 7050 aluminum alloy.
[0030] In some alternative embodiments, the support 4 has a rotating shaft and two bases connected by the rotating shaft. The two bases are fixed to the bottom of the nest-shaped receiving groove. The fixed mooring ring 5 is a semi-circular ring, and the two ends of the semi-circular ring are rotatably connected to the rotating shaft through pin holes.
[0031] In some alternative embodiments, as Figure 1 shown, the nest-shaped receiving groove has four first threaded through holes, and each of the two bases of the support 4 has two second threaded through holes. After the first threaded through holes and bolts pass through the first threaded through holes and the second threaded through holes, they are threadedly connected to the threaded holes of the floor cross beam 9 located below the floor beam 1.
[0032] In this embodiment, the fixed mooring ring interface 2 is arranged directly above the floor lower frame, that is, the floor cross beam 9. After four long bolts pass through the threaded holes at the bottom of the nest-shaped receiving groove of the support 4 and the fixed mooring ring interface 2, they are connected and fixed to the flange strip of the floor lower frame, so as to be able to transfer the load to the floor cross beam 9.
[0033] In some alternative embodiments, an anti-wear member 6 conforming to the inner surface of the nest-shaped receiving groove is provided between the support 4 and the nest-shaped receiving groove of the fixed mooring ring interface 2.
[0034] In some alternative embodiments, the mooring slide rail interface 3 is located between two fixed mooring ring interfaces 2. In this embodiment, the mooring slide rail interface 3 and the fixed mooring ring interface 2 are arranged at intervals. As described above, the fixed mooring ring interface 2 corresponds to the floor cross beam 9 below, so it can be known that the mooring slide rail interface 3 is arranged between two floor cross beams 9. In this embodiment, the floor beam comprehensively arranges the fixed-point mooring and the mooring slide rail on the same track, which can greatly increase the number of mooring points on the floor of the aircraft cargo hold, facilitate the connection of mooring ropes, and is conducive to the rational use of the cargo hold space.
[0035] In some alternative embodiments, as Figure 3 and Figure 4As shown, the mooring slide rail 8 has a rail surface 82, on which a rail groove 84 is formed. The mounting hole interfaces 81 are evenly distributed along the groove direction of the rail groove 84. In this embodiment, the multiple mounting hole interfaces 81 ensure the versatility and flexibility of the mooring slide rail. This arrangement can take into account the installation interface requirements of seats, pallets, stretcher stations, etc., and has strong adaptability.
[0036] In some alternative embodiments, the rail surface 82 is supported by a support web 83. The bottom end of the support web 83 has a support flange 85, and the support flange 85 is bolted to the floor beam web at the bottom of the mooring slide rail interface 82.
[0037] As Figure 5 shown, the rail surface 82, as the main structure of the mooring slide rail 8, can be integrally designed with the underlying support structure. In alternative embodiments, it can also be fixed to the underlying support structure. When connected by a fixing method, in addition to the support web 83 and the support flange 85, there is also a connecting plate or an upper flange structure above the support web 83. The connecting plate or the upper flange structure is bolted to the bottom plate of the rail surface 82, and the support flange 85 is screwed to the floor beam web, so as to transfer the equipment load connected to the mooring slide rail to the floor beam.
[0038] In some alternative embodiments, the mooring slide rail 8 is machined from aluminum alloy or titanium alloy. In this embodiment, it is preferably used that the mooring slide rail with a high usage frequency is made of titanium alloy, which has strong load-bearing capacity and good wear resistance.
[0039] The above is only the specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
