Technical Field

[0001] The invention relates to the technical field of teaching aids, and more specifically, to a practical demonstration teaching aid for teaching civil aviation ground traction equipment. Background Art

[0002] In the teaching of aircraft traction equipment design, teachers used to use PPT plus video to teach the working principle and equipment structure of traction equipment. There were no specific teaching aids, and students could not understand how the equipment operated and worked through hands-on observation. Teaching aids are the general term for various tools used to enable students to intuitively and vividly understand the teaching content and the tools used by teachers when teaching. Teaching aids are the abbreviation of teaching aids. Teaching aids can improve students' learning interest, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking abilities. To this end, a practical demonstration teaching aid for civil aviation ground traction equipment teaching is proposed. Summary of the invention

[0003] In view of the above problems, the present invention provides a practical demonstration teaching aid for teaching civil aviation ground traction equipment with complete functions and reasonable structural logic.

[0005] The power system includes an on-board power supply, a drive motor, and a motor control system; the clamping device includes a fixed clamp, an adjustable clamp, a limit baffle, a fixed support rod, a sliding support rod, and a rotating assembly;

[0006] The lifting device includes a lifting cylinder and a lifting rod; the functional module area includes a depth camera, a laser radar, a vision-assisted camera, a sensor fusion, a 5G communication positioning module, a vehicle-mounted control panel and a communication module.

[0007] The connected functional modules enable trainees to directly observe and experience how the barless aircraft towing equipment integrates automatic control, obstacle, identification and other functions in the high-speed and heavy-load mode of towing aircraft departure.

[0008] Wherein, the clamping device also includes a locking piece, which is slidably connected to the fixed support rod, abuts against the sliding support rod, and is located on a side of the fixed support rod close to the fixed support rod.

[0009] Wherein, the lifting device further comprises a lifting plate, the lifting plate is fixedly connected to the lifting rod and is located on a side of the lifting rod close to the vehicle frame.

[0010] The various functions of the functional module area are composed of components that play their respective functions. In order to maintain the economy of the teaching aids, the present invention selects low-cost components that can play similar functions as replacements.

[0011] In summary, the beneficial effects of the present invention are as follows:

[0012] Through the above technical solution, a teaching aid with complete functions, simple operation, and economical and efficient is constructed with the rodless aircraft towing equipment as a replica prototype, which can bring visual impact to the students and clearly observe the structure and function of each part of the rodless aircraft towing equipment, thereby helping them to understand the working principle of the rodless aircraft towing equipment;

[0013] In addition to the overall structure, the main system components are also set up to enable students to understand the working principles and structures of each system separately, while expanding the scope of application so that students can apply this principle to other parts;

[0014] The teaching aid can not only enable students to understand the advanced functions of the rodless aircraft towing equipment, but also realize the economy of the teaching aid by installing a low-cost alternative structure that can exert advanced functions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but the scope of protection claimed is not limited to the description.

[0022] Embodiment 1:

[0023] A clamping device of a practical demonstration teaching aid for teaching civil aviation ground traction equipment can clamp aircraft of different sizes accordingly, and the teaching aid is used to demonstrate the process of aircraft traction equipment towing an aircraft, so that trainees can more clearly observe how the equipment clamps and holds up the aircraft.

[0024] Embodiment 2:

[0025] The mechanical system retains the engine flywheel and the transmission components behind it including the clutch, gearbox, drive shaft, etc. without changing the operating performance of the rodless aircraft traction equipment.

[0026] Separately observing the mechanical system and power system of aircraft traction equipment and understanding the components and working principles of the system will help students understand the transmission system of civil aviation traction equipment.

[0027] Embodiment 3:

[0028] Based on Example 1 and Example 2, a vibration test was conducted using the vibration environment specified in GJB 150.16A-2009 “Test Methods for Test Environment of Military Equipment” as a loading excitation.

[0029] Taking the cabinet loaded with electrical equipment as the test object, the horizontal displacement of the GTK-L type vibration isolator at the bottom is ±8mm, and the horizontal displacement of the GBJ-180BK type side vibration isolator is ≤3mm, which effectively limits the horizontal displacement of the upper part of the equipment.

[0030] Embodiment 4:

[0031] Based on Example 1 and Example 3, an accordion protective cover is provided between the bottom of the cabinet and the bottom shock absorber. The elasticity of the accordion protective cover can prevent the cabinet bottom plate from colliding with the connection when the cabinet vibrates.

[0032] Embodiment 5:

[0033] Based on Example 1, according to the specific size of the on-board electrical equipment, select the appropriate plug-in box, place the L-shaped guide rail support on the cabinet frame slide rail surface, adjust the installation space of the electrical equipment, and use the positioning pin guide sleeve and electrical combination for fastening to prevent the equipment from vibrating during driving. Select plug-ins of different sizes and qualities and put them into the cabinet.

[0034] Embodiment 6:

[0035] Based on Example 1, the cabinet frame is made of aluminum alloy profiles connected by screws, and a lightweight design is performed without affecting the rigidity of the cabinet frame. By matching the real stress curve, the material with less stress in the aluminum alloy profile is removed to perform a lightweight design.

[0036] Embodiment 7:

[0037] Based on Example 1, the cabinet doors include left cabinet door, right cabinet door, front door, and rear door, and are made of aluminum honeycomb composite material. The composite material structure matrix is ​​filled with aluminum honeycomb inside and covered with 0.5mm aluminum plate outside. Compared with metal cabinet doors, aluminum honeycomb composite cabinet doors can effectively reduce structural mass and have strong adaptability. Compared with carbon fiber composite cabinet doors, they have advantages such as good economy and short processing cycle.
