[0026] Currently, the front end of the aircraft toe plate is connected to the rear end of the cargo bridge through two single and double ear joints, and the upper wall plate and the lower wall plate are connected to the upper wall surface and the lower wall surface of the rear end of the cargo bridge. A plurality of longitudinal beams are set at the rear end of the toe plate. Based on this, this application provides an aircraft cargo bridge rear end toe plate end support structure, such as Figure 1-Figure 2 Shown, including:

[0027] Four strip plates 1 are V-shaped and arranged in a transverse direction; the bottom end of each strip plate 1 is connected to the web of each longitudinal beam at the rear end of the toe plate, and can be connected by bolts;

[0028] Two connecting plates 2 are connected to the four strip plates 1 in the transverse direction and are arranged crosswise with the strip plates 1. They can be welded or integrally formed.

[0029] The skin 3 is covered on the outside of the four strip plates 1 and the two connecting plates 2, and can be connected to the edges of the four strip plates 1 and the two connecting plates 2 by screws or welding;

[0030] The edges of both ends of the skin 3 extend toward the bottom end of the belt plate 1 and are connected to the edge strips on both sides of the longitudinal beams at the rear end of the toe plate, and can be connected specifically by bolts.

[0031] The support structure for the end of the toe plate at the rear end of the aircraft cargo bridge disclosed in the above embodiment has a simple overall structure and is light in weight. When the cargo bridge is lowered, it can be located below the skin 3 at the top end of the four strip plates 1 and in contact with the ground. The force transmission path is simple, and a stable support can be formed for the rear end of the toe plate and its cargo bridge. The four strip plates 1 and the two connecting plates 2 are designed to be cross-arranged, and the overall structure is stable.

[0032] Furthermore, in the above-mentioned aircraft cargo bridge rear end toe plate end support structure, the bottom ends of the four strip plates 1 have V-shaped notches to reduce the overall mass of the structure.

[0033] Furthermore, in the above-mentioned aircraft cargo bridge rear end toe plate end support structure, the top ends of the four strip plates 1 have circular through holes to reduce the overall mass of the structure.

[0034] Furthermore, in the above-mentioned aircraft cargo bridge rear end toe plate end support structure, two pairs of double ear plates 4 are arranged between the two outermost belt plates 1 and the adjacent belt plates 4, are arranged parallel to the belt plates 4, and are arranged crosswise with the two connecting plates 2;

[0035] There are two notches on the skin 3, exposing the top ends of the two outermost strips 1 and the two pairs of double-ear pieces 4. When the cargo bridge is lowered at a large slope, the two joints at the front end of another separate toe plate can be connected to the top ends of the two pairs of double-ear pieces 4, and the upper and lower wall panels at the front end of the separate toe plate can be placed above and below the skin 3, so as to extend the length of the cargo bridge, reduce the slope when the cargo bridge is lowered, and reduce the risk of cargo transportation.

[0036] Furthermore, in the above-mentioned aircraft cargo bridge rear end toe plate end support structure, a plurality of process maintenance and drainage ports can be designed under the skin 3, and each process maintenance and drainage port is connected to each independent space formed by the cross-intersection of four strip plates 1 and two connecting plates 2, so as to facilitate the maintenance of the structure and drainage, and have a weight reduction effect.
