The chassis bottom is flat, with four roller beams added to the bottom, consistent with the roller beams at the bottom of loading and unloading platform vehicles and the cargo hold of a certain type of transport aircraft. Limiting edge tooth interfaces are added to both sides of the chassis, and the limiting edge teeth 1 can be detachably installed using a screw connection. Figure 3The chassis is designed for quick connection using bolts. After use, the side teeth can be removed. Side tooth placement boxes are located on both sides of the chassis, with three sets on each side, each holding a corresponding side tooth 1 on the left and right sides. The upper part of the chassis is covered with standard container wood flooring. Corner fittings are installed at the four corners of the chassis bottom, welded to the corner posts and side beams for bottom lifting, towing, and securing. These fittings can also be connected to aircraft winch cables for boarding and towing. The bottom of the chassis also features riveted aluminum plates, ensuring a flush surface with the corner fittings to meet roll-on / roll-off requirements. The chassis's bottom crossbeams are rectangular beams with high load-bearing capacity, capable of withstanding forklift loading operations. Each floor panel can withstand a concentrated load of 1.5 tons.

[0035] Container standard wood flooring is a special type of plywood made of multiple layers of veneers of equal or unequal thickness bonded together with adhesive. The top and bottom three layers of veneer each have a longitudinal grain-oriented structure, while the core layers have veneers with adjacent grains perpendicular to each other. This special structure ensures high strength and excellent wear resistance for container flooring. The wood flooring undergoes high-temperature fumigation and surface coating processes to prevent mold growth. The flooring is positioned at a certain height above the ground to avoid direct contact with the surface.

[0036] The left and right side walls have the same layout, both constructed from corrugated container panels welded together. A ventilator 2 is installed on the upper part of each side wall. Figure 4 To meet the requirements of cabin ventilation, rain and dust protection, and air transport decompression, the two side walls are also equipped with custom-designed ventilation interfaces specifically for aircraft air conditioning vehicles.

When in use, it is opened and connected to the air outlet of the air conditioning vehicle system to quickly connect to the dehumidification of the air conditioning vehicle to ensure constant temperature and humidity inside the cabin. There are 6 ladders on the right side wall and 2 ladders on the top for going up and down the cabin roof. There are forklift slots on the lower part of both side panels, which are used in conjunction with the chassis forklift slots for forklift loading and unloading operations.

[0037] The container corrugated sheets are made from high-quality Q355 carbon steel sheets using a mold roller forming process. Roller-formed corrugated sheets offer higher strength and a better appearance compared to ordinary steel sheets. The corrugated sheets are then welded together automatically. Automated welding offers significant advantages over manual welding in terms of appearance, weld quality, and weld strength. Furthermore, the use of corrugated sheet structures in the sidewalls reduces the need for vertical beams on the side walls, minimizing the container's weight while still meeting strength requirements. (Sidewall corrugated sheet structure.)

[0038] like Figure 6The front and rear doors are standard container doors, consisting of a steel frame 6 and double doors. The door panels 5 are connected to the steel frame 6 by hinges 8, enabling opening and closing. The opening angle is ≥260°. The hinges 8 are standard hinges with high load-bearing capacity. After the door is opened to 90°, the outermost edge of the door frame can withstand a static load of 150kg without permanent deformation. Door hooks are installed below the steel frame 6 for limiting and fixing the door panels 5 after opening. Sealing strips are riveted to the edges of the door panels 5 to fill the gap between the door panels 5 and the cabin body for waterproofing and sealing. Locking rods 7 are installed on the door panels 5 to achieve the locking function of the door end. A document box is welded to the inside of the door panels 5 for storing documents, facilitating on-site retrieval and preventing document loss.

[0039] The roof panel is constructed from standard container roof panels and is designed to withstand a uniformly distributed load greater than 2 kN / m. 2 Concentrated load > 3kN / 0.36m 2 As required, the top plate is equipped with corner brackets at all four corners, welded to the corner posts and side beams, for securing the container during hoisting and transportation. The container top plate is made of high-quality carbon steel plate through die stamping. Stamped top plates are stronger and less deformed than ordinary steel plates, and have better water drainage, preventing water accumulation on the top of the container that occurs with ordinary flat steel plates. The top plates are welded together using an automated machine. Automated welding offers significant advantages over manual welding in terms of appearance, weld quality, and weld strength.

The loading adapter can quickly cooperate and lock with the existing bomb-loading vehicle to realize hoisting and lifting, and at the same time realize the rapid docking and pushing of the trolley 12, so as to achieve the purpose of quickly and effortlessly pushing the launcher into the cabin.

[0042] like Figure 10The aforementioned rack trolley 12 has a long, narrow structure with multiple rollers on both sides. These rollers engage with the rack trolley track on the detachable shelf and the slide rail 9 for loading the adapter device, allowing it to slide along the track. Limit locks are installed at both ends of the rack trolley 12 to secure it to the detachable shelf. These limit locks can withstand three times the overload in the forward and backward directions. The upper surface of the rack trolley 12 is used to install rack support pillows 13. The detachable shelf and the rack trolley 12 as a whole can withstand a forward dynamic load of 3g and a downward dynamic load of 4.5g. Through statistical optimization, seven different rack trolley combinations were designed based on several main size ranges of rack distribution. This ensures that one rack trolley 12 can meet the loading, transportation, and storage needs of weapon racks within a specific range. Furthermore, all rack trolleys 12 have the same structure and installation method, exhibiting high versatility and adaptability.

[0043] like Figure 11 The aforementioned hanger support 13 is made of 7-series aluminum welded together, ensuring strength while reducing weight. The bottom of the hanger support 13 is equipped with a bolt connection plate for detachably fixing it to the hanger trolley 12 using U-bolts. The fixed position of the hanger support 13 on the hanger trolley 12 is adjustable to accommodate various lengths of loaded items. The upper end of the hanger support 13 serves as a support surface, on which a wear-resistant rubber plate is installed for shock absorption. Binding straps are provided on both sides of the hanger support 13 for secure fastening. Three different specifications of hangers are designed for different models of external equipment, suitable for seven types of external equipment on a certain type of aircraft. The positions of these hangers can be freely interchanged and installed on the hanger trolley 12 according to actual usage requirements, demonstrating good interchangeability.
