Problems solved by technology

[0003] In the previous theoretical course training and teaching process, due to the complex structure of the helicopter, the flexible and changeable rescue training process, and various rescue modes, it is difficult for students to understand the helicopter rescue process through the explanation of the courseware during the teaching process. The rescue training simulator demonstrates to students, but the consumption cost is high, and the safety of personnel cannot be guaranteed

Embodiment 1

[0026] A single set of lifting means that the lifeguard uses a rescue set to rescue people in distress. It can be used to rescue people who are conscious and in good physical condition. It is also the most common method of general helicopter rescue. The specific use of rescue sets The method is that the lifeguard's right hand pinches the rescue sleeve, the left hand follows the sling to find the hook from under the rescued's arm, lifts the hook with one hand to straighten the sling, and tightens the rescue lasso loop, so that the winch driver can pass the rescue winch wire rope Lift the lifeguard and the rescued into the helicopter together.

[0027] The demonstration of single set of lifting with teaching equipment is introduced as follows:

[0028] (1) The cabin is at the highest position, and the simulated aircraft height is 60m; the translation mechanism moves downward in the vertical direction, the cabin descends to 0.2m from the lower platform, and the simulated rescue helico...

Embodiment 2

[0034] Double-set lifting means that lifeguards use two rescue sets to rescue people in distress. For people who are unconscious, unconscious, but have no physical injuries or fractures, use this method to rescue people, and usually rescue people who fell into the water at sea. Double rescue kits are also used, one rescue kit is placed under the arm of the rescued, and the second rescue kit is placed at the knee joint of the rescued. Since the training of the double-set lifting rescue mode is basically the same as the training of the single-set lifting, the demonstration using teaching equipment is exactly the same as the single-set lifting, so I will not repeat the process here.

Embodiment 3

[0036] Stretcher lifting refers to rescue stretchers used by lifeguards to rescue people in distress. It is mainly used to rescue critically ill patients or people with broken bodies. The stretcher can fix the head, body and limbs of the rescued, which is convenient for helicopter lifting.

[0037] When using teaching equipment to demonstrate stretcher lifting, it is exactly the same as the first three steps of single set lifting. Now starting from the fourth step, the demonstration of stretcher lifting mode is introduced as follows:

[0038] (1) After the first three steps of operation, the engine room moves to above the distress position. The hoisting system controls the steel cable to continue lowering to the ground level, simulating the lifting of the lifeguard to the ground.

[0039] (2) Just after the steel cable was lowered to the ground, the translation mechanism led the engine compartment to move 0.04m to the left, and the simulated aircraft was waiting at 2 units on the lef...

Abstract

The invention provides a helicopter rescue teaching instrument. The instrument comprises a fixing frame and a simulated helicopter cabin which is rotatably connected to the fixing frame through a plurality of hanging rods. The cabin comprises a cabin body, a supporting mechanism, a swing mechanism and a hoisting mechanism. Connecting points connected with the hanging rods are arranged in the circumferential direction of the supporting mechanism. The slewing mechanism is arranged above the supporting mechanism; the cabin body is connected below the supporting mechanism; the hoisting mechanism is arranged in the cabin body; a lifting appliance capable of extending out of the cabin body is arranged at the tail end of the cabin body, the motion process of a helicopter in the rescue process issimulated by changing the spatial position of the simulated helicopter cabin relative to the fixing frame, the steering motion of the helicopter in the horizontal plane is simulated by operating the swing mechanism, and a rescue winch system of the helicopter is simulated by operating the hoisting mechanism. The instrument is compact in structure and convenient to carry, helicopter movement and various rescue modes can be directly demonstrated in class, the training cost is saved, and the risk of safety accidents of students in the actual training process is reduced.

Description

Technical field [0001] The invention relates to the technical field of teaching aids, in particular to a helicopter rescue teaching instrument. Background technique [0002] The most common and effective way of aviation emergency rescue is helicopter rescue. Helicopter rescue requires the cooperation of helicopter pilots, winches and lifeguards. In the rescue process, the pilot controls the helicopter, the winch operator operates the rescue winch, and the lifeguard goes out of the cabin to rescue people at the same time. In view of different distress situations, different rescue equipment is hoisted by the rescue winch outside the helicopter to rescue personnel. The training of helicopter rescue crews requires preliminary theoretical courses, the subject training of winches and lifeguards on the helicopter rescue simulator, and finally a certain period of training and assessment on the real helicopter before becoming a professional rescuer. [0003] In the preliminary theoretical...
