Description

Technical Field

[0001] The invention belongs to the technical field of transportation and loading and unloading, and in particular relates to a fast-assembly heavy-load auxiliary cargo bridge for a transport aircraft. Background Art

[0002] The height of the cargo hold of a transport aircraft is usually about 2000mm from the ground. The tail of the cargo hold is an automatically opened ramp device. When the ramp is opened, it contacts the ground. Usually, the angle between the ramp and the ground is about 15°. For wheeled self-propelled equipment entering the transport aircraft, due to the short length of the ramp and the large slope, it is usually difficult to meet the passability requirements of the self-propelled equipment, and it is impossible to ensure smooth entry into the cargo hold of the transport aircraft. Therefore, it is necessary to add devices such as an extended auxiliary cargo bridge for entering the cargo hold. For transportation tasks, the loading time requirements are high. The extended auxiliary cargo bridge needs to have the ability to assemble and combine quickly, and can be quickly erected and withdrawn within a limited time. After loading is completed, it can be quickly transferred and used with the aircraft; and as the weight and size of wheeled self-propelled equipment become larger and larger, the load-bearing capacity of the auxiliary cargo bridge is required to be high during loading. It needs to be safe and reliable, and the load-bearing capacity must be no less than 50 tons.

[0003] In the prior art, there are auxiliary cargo bridges for transport aircraft to load and unload self-propelled equipment, but the cargo bridges are composed of many parts and the assembly process is cumbersome, which affects the loading and unloading time and is difficult to meet the time requirements of transportation. In addition, the cargo bridge has limited carrying capacity and cannot meet the loading requirements of heavy equipment. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention proposes a heavy-load auxiliary cargo bridge for rapid assembly of a transport aircraft. The cargo bridge has the ability to be quickly erected and withdrawn and has a large load-bearing capacity, ensuring that heavy-loaded self-propelled equipment can smoothly enter and exit the transport aircraft. The auxiliary cargo bridge is easy to store and can be carried randomly.

[0005] The invention discloses a fast-assembled heavy-load auxiliary cargo bridge for a transporter, which is mainly composed of an adjustable support, an extended cargo bridge and a pallet. It has two modes: working and transporting. In the working mode, the adjustable support is used to support the ramp of the transporter, and the extended cargo bridge is quickly assembled to form two rows of load-bearing cargo bridges to meet the self-loading of equipment; in the transport mode, the load-bearing cargo bridges are quickly withdrawn, combined and stacked, and quickly locked and fixed on the pallet to meet the random carrying of the auxiliary cargo bridge.

[0006] In the working form, the adjustable support is placed at the bottom of the conveyor ramp, and the extended cargo bridge is quickly assembled through the segmented transition section and overlapped with the conveyor ramp, which can meet the needs of self-propelled equipment for loading.

[0007] In the described transport form, the divided transition sections are placed on the pallet in sequence. In order to meet the size requirements of the conveyor, some of the transition sections are stacked and fixed by the left and right side positioning guide devices. After being packed together and entering the conveyor cabin, they are quickly fixed to the conveyor through the pallet corner fittings, which facilitates the random carrying of the entire auxiliary cargo bridge.

[0008] The extended cargo bridge is composed of two rows, each row is composed of a plurality of block transition sections that are quickly overlapped and assembled, and the transition sections can be quickly overlapped and positioned by front and rear hooks, thereby achieving reliable connection between the plurality of block transition sections and ensuring the safety and reliability of the self-propelled equipment during driving.

[0009] The block transition section is the main load-bearing structure during the loading process of the self-propelled equipment. The main structure of the transition section is welded from aluminum plates. The transition section is designed to have a certain slope according to transportation requirements. Two quick hooks are set at the front of the transition section, two hanging grooves are set at the rear of the transition section, and positioning guide devices are set on the left and right sides of the transition section for rapid withdrawal of the transition sections during transportation. A pedal is installed at the front end of the transition section overlapped with the conveyor ramp, which is overlapped on the conveyor ramp to facilitate the self-propelled equipment to smoothly drive from the extended cargo bridge to the conveyor ramp.

[0010] The pallet is the basis for the random carrying of the auxiliary cargo bridge. The four corners of the pallet adopt the corner fitting structure of a general container or a cabin. When the auxiliary cargo bridge is in a transport form, the corner fitting structure of the four corners of the pallet can be quickly fixed inside the transport cabin to ensure reliable fastening during the transportation process.

[0011] The adjustable support is placed at the bottom of the conveyor ramp. The adjustable support can be adjusted in height through four supporting legs and has a certain height adjustment function. The height of the ramp is adjusted to ensure that the overlap between the conveyor ramp and the extended cargo bridge is reliable after adjustment.

[0012] The beneficial effects of the present invention are

[0013] 1. It has the characteristics of simple structure and quick connection structure between blocks, which can realize rapid assembly. When implementing transportation tasks, it can significantly reduce loading time, which is of great significance for special transportation tasks.

[0014] 2. The auxiliary cargo bridge structure adopts a plate shell structure with good bending resistance and strong bearing capacity. It can meet the loading and transportation of heavy equipment and solves the difficulties in air transportation of heavy equipment.

[0015] 3. The auxiliary cargo bridge has a small size in transport state and reliable connection, which is convenient for random carrying. BRIEF DESCRIPTION OF THE DRAWINGS
