Aerial delivery mechanism

Abstract

According to the air delivery mechanism, under the condition that an air delivery task is not executed, the position of goods is kept unchanged relative to an airplane under the action of the limiting assembly. When air-drop is needed, the limiting assembly releases limitation on goods and enables the goods to be placed on the idler wheels, the pushing mechanism pushes the goods to move on the idler wheels, and under the combined action of the pushing mechanism and the limiting and positioning assembly, the movement speed and distance of the goods are controlled, and the posture of the goods is controlled till the goods are pushed to the position over an opening of an air-drop cabin door. And then, the goods vertically leave the cabin door under the action of the gravity of the goods or the auxiliary throwing assembly, and attitude-controllable air-drop is achieved. According to the air delivery mechanism, vertical delivery of air-dropped goods can be achieved, it can be guaranteed that the speed and posture of the goods are basically controllable after the goods leave an airplane, meanwhile, the requirement for the opening size of an air-dropped cabin door of the airplane is lowered, and then the weight of an airplane body is lowered.

[0029] The drawings will be described below in combination with the Figs. 1-2 The present application will be further described in detail.

[0030] The present application provides an aerial delivery mechanism, comprising: a roller 1, a limiting assembly 2, a pushing mechanism 3, a limiting positioning assembly 4, a cargo hold floor 6 and an assisted dropping assembly 7.

[0031] Specifically, the cargo hold floor 6 is provided with airdrop hatch opening, the pushing mechanism 3 comprises a pushing track and a pushing part, the pushing track is installed on the cargo hold floor 6 and extends to the airdrop hatch opening, and the pushing part is arranged in the pushing track and can move along the pushing track. Preferably, the pushing part of the pushing mechanism 3 is a hydraulic actuator, under the pushing of the pushing part, the cargo 5 on the roller 1 can move towards the airdrop hatch opening.

[0032] The rollers 1 are symmetrically arranged along both sides of the pushing mechanism 3, the rotation shafts of the rollers 1 are fixedly connected with the cargo compartment floor 6, the rollers 1 can rotate around the rotation shafts, and the goods 5 are placed on the rollers 1. In the preferred embodiment of the present application, the tangent direction of the upper surface of the roller 1 is parallel to the direction of the movement of the goods 5, so as to better assist the movement of the goods 5 on the roller 1 towards the air drop hatch opening. In addition, the rollers 1 located on the same side of the pushing mechanism 3 are preferably arranged in multiple rows, each row including multiple rollers 1 arranged closely, thereby improving the stability of the movement of the goods 5.

[0033] The limiting assemblies 2 are symmetrically arranged along both sides of the pushing mechanism 3, and the limiting assemblies 2 are located outside the rollers 1. The limiting assembly 2 includes a limiting part and a driving part, the driving part can drive the limiting part to move in a direction perpendicular to the cargo compartment floor 6, thereby lifting the goods 5 so that the lower surface of the goods 5 is away from the upper surface of the roller 1. The limiting assembly 2 has two position states, in the lifting position 21, the lower surface of the goods 5 is away from the upper surface of the roller 1, and the pushing part of the pushing mechanism 3 cannot push the goods 5 to move; in the lowering position 22, the lower surface of the goods 5 is attached to the upper surface of the roller 1, and the pushing part of the pushing mechanism 3 can push the goods 5 to move.

[0034] In the preferred embodiment of the present application, the limiting assemblies 2 located on the same side of the pushing mechanism 3 are arranged in one row, and the row includes multiple limiting assemblies 2 arranged closely, thereby the goods 5 can be controlled to stay at any desired position. In the embodiment, the limiting part of the limiting assembly 2 is a convex limiting boss, and the driving part of the limiting assembly 2 is a driving motor.

[0035] The limiting and positioning assembly 4 includes a positioning rod 42 and an elastic rope 41, two positioning rods 42 are symmetrically arranged along both sides of the pushing mechanism 3 and close to the air drop hatch opening, and the elastic rope 41 connects the two positioning rods 42. It can be understood that the elastic rope 41 is arranged in multiple strips along the height direction of the positioning rod 42, which is beneficial to maintain the posture of the goods 5.

[0036] The auxiliary dropping assembly 7 includes a mounting part 72 and a moving part 71, the mounting part 72 is fixedly connected with the machine body structure, the moving part 71 is located above the air drop hatch opening, the moving part 71 can move in a vertical direction in the mounting part 72, and the moving part 71 can push the goods 53 to move downwards in a direction perpendicular to the cargo compartment floor 6.

[0037] As Fig. 1 and Fig. 2As shown, during the loading of the goods, the pushing mechanism 3 moves towards the area of the cargo compartment floor 6 laid by the rollers 1, the limiting assembly 2 moves to the lowered position 22 in the direction perpendicular to the cargo compartment floor 6, the limiting assembly 22 is lower than the contact surface of the rollers 1 and the goods 5, and the goods 5 can move on the rollers 1 under the manual pushing in the direction away from the air drop hatch opening, i.e. away from the auxiliary drop assembly 7. When moved to the required position, the limiting assembly 2 moves to the raised position 21 in the direction perpendicular to the cargo compartment floor 6, limiting the further movement of the goods 5, and the loading process is completed.

[0038] During the transportation of the goods, the goods 5 are relatively stationary with the cargo compartment floor 6 under the action of the limiting assembly 2.

[0039] It can be understood that the goods 5 are not limited to one, but one or more. In this embodiment, two goods 5 are taken as an example to describe the delivery process of the goods.

[0040] During the drop of the goods, the limiting assembly 2 of the goods 5 near the air drop hatch opening position is lowered from the raised position 21 to the lowered position 22, driving the goods 5 to move downwards until the lower surface of the goods 5 is in close contact with the rollers 1. After the pushing part of the pushing assembly 3 passes through the bottom of the goods 5 away from the air drop hatch opening, the goods 5 near the air drop hatch opening position moves in the tangential direction of the upper surface of the rollers 1 to the elastic rope 41 of the limiting positioning assembly 4, the pushing part of the pushing assembly 3 continues to push the goods 5 to move, the elastic rope 41 is stretched under the action of the movement, and the goods 5 keeps the posture stable and the speed controllable under the joint action of the pushing part and the elastic rope 41, until the goods 5 moves to completely leave the cargo compartment floor 6 and is located directly above the air drop hatch opening. At this time, the goods 5 can move downwards under the action of gravity, or can move downwards under the action of the moving part 71 of the auxiliary drop assembly 7, until leaving the entire air drop mechanism. The drop process of the goods 5 away from the air drop hatch opening is similar to the above process, and will not be described in detail.

[0041] In the case that the air drop mechanism of the present application does not perform the air drop task, the goods 5 keeps the position relatively unchanged to the aircraft under the action of the limiting assembly 2. When the air drop is needed, the limiting assembly 2 releases the limitation on the goods 5 and places the goods 5 on the rollers 1, the pushing mechanism 3 pushes the goods 5 to move on the rollers 1, and the movement speed, distance and posture of the goods 5 are controlled under the joint action of the pushing mechanism 3 and the limiting positioning assembly 4, until the goods 5 is pushed to the air drop hatch opening directly above, and then the goods 5 vertically leaves the hatch under the action of its own gravity or the auxiliary drop assembly 7, realizing the air drop with controllable posture.

[0042] The aerial delivery mechanism of the present application can realize vertical delivery of the air-dropped goods 5, and can ensure that the speed and attitude of the goods 5 after leaving the airplane are basically controllable; when applied to the aircraft, the requirement for the opening size of the air-dropped cabin door of the airplane can be greatly reduced, and the effect of reducing the structure weight of the airplane is achieved.

[0043] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in 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.
