Description

Technical Field

[0001] The utility model provides a foldable aircraft annular radiator disassembly and assembly device, belonging to the technical field of annular radiator disassembly and assembly. Background Art

[0002] As the power of aircraft engines increases, the maximum speed of aircraft also increases significantly. For the annular radiator installed in the aircraft air intake, not only higher requirements are placed on the heat exchange performance of the annular radiator, but also more stringent requirements on the strength of the annular radiator. The heat dissipation principle of the annular radiator is to achieve heat dissipation through heat exchange between the cold source (ram air) and the heat source (high temperature medium from the engine) at the heat exchange interface formed by the corrugated plate.

[0003] At present, when disassembling and assembling the annular radiator on the aircraft, since the annular radiator is located at a relatively high height on the aircraft, the operator is often required to work at a certain height during the disassembly and assembly work. However, during the disassembly and assembly, since the annular radiator has a certain weight and height, once an operating error occurs, the annular radiator is likely to fall from a high altitude, which poses certain safety hazards, and the annular radiator is easily damaged when falling from a high altitude. Utility Model Content

[0004] The technical problem solved by the utility model is that when disassembling and assembling the annular radiator on the aircraft, once an operating error occurs, the annular radiator is likely to fall from a high altitude, which poses certain safety hazards, and the annular radiator is easily damaged when falling from a high altitude.

[0006] Furthermore, the adjustable support rod is provided with a plurality of adjustment holes, and the top of the front support frame assembly component is provided with adjustment bolts matching with the adjustment holes.

[0007] Furthermore, the rear support frame assembly component has the same structure as the front support frame assembly component, and the support pad is made of wood material and wrapped with soft cloth.

[0008] Furthermore, a lifting ring is provided on the top of the structural frame.

[0009] Furthermore, a rear support ear and a front support ear are provided at the bottom of the structural frame, and the structural frame is assembled and connected with the rear support ear and the front support ear through quick-release pins, and the structural frame is connected with the front support point bracket and the rear support point bracket on the upper part of the installation vehicle through quick-release pins.

[0010] Furthermore, the telescopic support rod comprises a main rod and a telescopic rod, and the side walls of the lower ends of the main rod and the telescopic rod are both provided with support blocks, and the support blocks are threadedly connected with an adjusting screw.

[0011] Beneficial effects of the utility model:

[0012] The aircraft annular radiator can be clamped and fixed on the outside of the telescopic support rod and the fixed support rod through the rear support frame assembly component and the front support frame assembly component, thereby facilitating the disassembly and assembly of the aircraft annular radiator and preventing the annular radiator from falling from a high altitude due to operational errors during the disassembly and assembly process, reducing safety hazards and preventing the annular radiator from falling and being damaged.
