Description

Technical Field

[0001] The utility model relates to the technical field of training simulation devices, in particular to a training device for disassembly and assembly of aircraft ducts and fuse protection. Background Art

[0002] In modern aircraft, the piping system is one of the main basic components of the aircraft system. It is used for the transportation and energy transfer of aircraft hydraulics, fuel, oxygen, air, water and other media. The aircraft piping system is composed of conduits, pipe sleeves, outer sleeve nuts, seals, pipe clamps, pipe joints, etc. Once the conduit or joint fails, it will cause system failure, and in serious cases, it will cause the aircraft to crash. Therefore, for aircraft maintenance personnel, mastering the pipeline identification, disassembly and assembly, sealing test and inspection of the piping system is a very important operational skill.

[0003] The standard for setting an aviation fuse is: pass the aviation fuse through a fastener (screw / bolt), then tighten it, and then pass it through another fastener (screw / bolt) and tighten it. The fasteners (screws / bolts) are braked against each other by connecting them in series to prevent the valve from loosening. That is, when a fastener (screw / bolt) tends to loosen, it will pull the fuse, causing the adjacent bolt to tend to tighten.

[0004] Currently, there are various types of equipment used for aircraft hard / soft hose line construction training, but the functions are single. It is impossible to realize aircraft hard / soft hose disassembly and connection, hard pipe bending, pipe joint production and pressure testing on one device. This brings certain difficulties for trainees to master the composition of the management system and troubleshooting methods. Utility Model Content

[0005] In view of this, the utility model provides a training device for aircraft duct disassembly and assembly and fuse insurance. By designing a training device for aircraft duct disassembly and assembly and fuse insurance, the disassembly and assembly of different types of ducts commonly used on aircraft and the fuse insurance making experiments of corresponding joints can be simulated, which solves the problem that the current training equipment for aircraft hard / soft pipe construction has various types and single functions, and it is impossible to complete the simulation experiment operations such as aircraft hard / soft pipe disassembly and assembly connection, hard pipe bending production, pipe joint production and pressure testing on one device, which is convenient for trainees to quickly and efficiently master the composition and troubleshooting methods of the management system.

[0006] In order to solve the above technical problems, the utility model provides a training device for aircraft duct disassembly and fuse insurance, comprising a bottom plate, a frame is arranged on the bottom plate, the frame is a frame structure, a duct display area, a pressure supply area, an oil pipeline disassembly and assembly area, a pneumatic pipeline disassembly and assembly area and a fuse insurance training area are arranged on the frame, the duct display area is located at the upper part of the frame, the duct display area includes a display board arranged at the upper part of the frame, a plurality of mounting holes are opened on the display board, and hooks for hanging the duct body are arranged in the mounting holes. The utility model can realize the display operation of different types of ducts commonly used on aircraft through the hooks, and can simulate the disassembly and assembly of different types of ducts commonly used on aircraft and the fuse insurance production experiment of corresponding joints by designing a training device for aircraft duct disassembly and fuse insurance, solves the problem that the current equipment for aircraft hard / soft pipe construction training is diverse in type and single in function, and cannot realize the simulation experiment operation such as aircraft hard / soft pipe disassembly and assembly connection, hard pipe bending pipe production, pipe joint production and pressure testing on one device, so that trainees can quickly and efficiently master the composition and troubleshooting methods of the management system.

[0007] The pressure supply area includes a hydraulic pressure supply area and a pneumatic pressure supply area which are arranged on the upper part of the bottom plate and on the right side of the frame. The oil pipeline disassembly and assembly area is arranged on the front side of the frame, and the pneumatic pipeline disassembly and assembly area is arranged on the rear side of the frame. The hydraulic pressure supply area includes an oil tank, a hand pump, a one-way valve, an oil filter, an accumulator, a hydraulic pressure gauge, a total pressure supply switch, a safety valve and a multi-component pipeline hydraulic pressure supply switch. The pneumatic pressure supply area includes an inflation nozzle, a one-way valve, a steam filter, a storage battery, a pneumatic pressure gauge, a total pressure supply switch and a multi-channel branch pipeline pneumatic pressure supply switch. The utility model can simulate the disassembly and assembly of the oil system pipeline through the hydraulic pressure supply area, and can artificially increase the pressure by using a hand-cranked hydraulic pump with the help of the hydraulic pressure supply system, so as to simulate the operation of the catheter under different pressure conditions. Working conditions, when removing the catheter, release the pressure through the oil return switch; then close the main pressure supply switch to realize the removal of the catheter. It should be noted here that: after the catheter is installed, before the hydraulic pressure supply system works, it is necessary to check the sealing of the installation joint after pressurizing with a hand-cranked hydraulic pump. The specific implementation method is that after the catheter is installed, use a gas cylinder to pressurize the pipeline, observe the sealing of the installation joint, and after testing the sealing of the installation joint, you can open the battery bottle and cooperate with the gas cylinder to pressurize, and then you can carry out the working simulation experiment of the hydraulic pressure supply system. When the experiment is completed, release the pressure by opening the pressure relief switch, then close the main pressure supply switch, remove the catheter, and continue with the next catheter disassembly and assembly experiment.

The specific operation method is to design various typical threaded connection types of connectors on the left side of the rack. Its main purpose is to be used for fuse insurance practice. Then the fuse can be wrapped around the conduit joint. The operator passes the aviation fuse through a fastener (screw / bolt), then tightens it, and then passes it through another fastener (screw / bolt) and tightens it. The fasteners (screws / bolts) are mutually braked by series connection to prevent the valves from loosening. That is, when a fastener (screw / bolt) tends to loosen, it will pull the fuse, so that the adjacent bolts tend to tighten. It should be noted here that different connection forms include; pipe joints with insurance lugs, T-shaped pipe joint nuts, slot nuts, bolts with angled insurance holes drilled on the bolt heads, hexagonal nuts with holes in the middle, hexagonal screws that are not in the same plane, butterfly nuts, cable adjustment screw sleeves, etc.

When the utility model is conducting an experiment, the output rod of the telescopic push rod is extended to push the support plate to contact the ground. At this time, the universal wheel is separated from the ground, thereby realizing the firm support operation of the training device. When the position of the training device needs to be moved, the operator starts the output rod of the telescopic push rod to retract it until the universal wheel contacts the ground. At this time, the lower part of the support plate is separated from the ground, and then the brake on the universal wheel is released. After the person manually pulls the handle to push the training device to a suitable position, he steps on the brake on the universal wheel, and then starts the output rod of the telescopic push rod to extend it to push the support plate to contact the ground. At this time, the universal wheel is separated from the ground, thereby realizing the firm placement operation of the training device, and the catheter disassembly and assembly experiment and the fuse making work can be carried out.
