Technical Field
[0001] The utility model relates to a parachute training device. Background Art
[0002] Parachute training is equipment or a system used to simulate the parachute landing process and provide parachute training for trainees. Currently, for parachute training equipment on the market, especially the larger-sized ones, the method of using a sliding vehicle to drive trainees away from the simulated cabin is mostly adopted. For the above-mentioned sliding vehicle, a two-wheel drive scheme is mostly used. This type of drive structure is simple and easy to design. However, there are also some inevitable problems, mainly manifested as easy stall and slow speed. Especially in the scenario of a long-distance track, when the track is long, there will inevitably be uneven situations. When the sliding vehicle passes through these sections, there will be a situation where the four wheels cannot contact the track. Especially when its two driving wheels are instantaneously separated from each other or a single one is separated, the sliding vehicle will have a situation of instantaneous power shortage or different speeds on both sides. At this time, if the vehicle speed is fast, there will also be a safety problem of derailment. Therefore, the above-mentioned type of sliding vehicle cannot provide a training scenario with a relatively fast moving speed for trainees. For this reason, the utility model provides a parachute training vehicle and its application device with a higher safety level and adaptable to a relatively fast moving speed.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0037] Please refer to Figures 1 to 8, a parachute training device, comprising an orbit group 1 and a training mobile vehicle 2, wherein,
[0038] The orbit group 1 includes two parallel and spaced sliders 11, and the training mobile vehicle 2 includes a vehicle frame 21, moving wheels 22, a driving motor 23, a synchronous driving member 24, an auxiliary limiting member 25, a lifting adjustment member 26, a harness suspension seat 27, and a lifting adjustment motor 28. Specifically,
[0039] There are four moving wheels 22, which are rotatably installed at the four corners of the vehicle frame 21 to form two front wheels and two rear wheels, enabling the vehicle frame 21 to move along the slider 11. The driving motor 23 is installed on the vehicle frame 21 and drives the four moving wheels 22 to rotate synchronously through the synchronous driving member 24, and drives the vehicle frame 21 to move forward or backward on the slider 11.
[0040] In this embodiment, the synchronous driving member 24 includes a first right-angle commutator 241, and there are four first right-angle commutators 241: one end of the transverse rotating shafts of the four first right-angle commutators 241 is respectively connected to the four moving wheels 22, and the other ends of the transverse rotating shafts of the two first right-angle commutators 241 of the rear wheels or front wheels are linked. The longitudinal rotating shafts of the two first right-angle commutators 241 on the same side of the vehicle frame 21 are linked through a longitudinal connecting rod 242, so as to realize the synchronous rotation of the four moving wheels 22.
[0041] On the basis of the above embodiment, in other embodiments, the driving motor 23 drives the first right-angle commutators 241 of the two rear wheels through another first right-angle commutator 241. Additionally, preferably, between the first right-angle commutator 241 and the longitudinal rotating shaft, and between the first right-angle commutator 241 and the first right-angle commutator 241, they are connected through a flat key sleeve coupling 243.
[0042] The auxiliary limiting member 25 is installed on both sides of the vehicle frame 21 and moves or rolls relatively along the slider 11. The vehicle frame 21 and the slider 11 are relatively fixed in the up-down and left-right directions through the auxiliary limiting member 25. On the one hand, it can improve the driving stability of the training mobile vehicle 2, and on the other hand, it can prevent the training mobile vehicle 2 from getting off the track during high-speed movement.
[0043] In one embodiment, the auxiliary limiting member 25 includes first limiting rollers 251, and there are also four first limiting rollers 251, which are respectively rotatably installed at the bottoms of the four corners of the vehicle frame 21 and roll along the inner side of the slider 11, with the rotating shafts in the vertical direction, so as to limit the left-right shaking of the training mobile vehicle 2 on the slider 11.
[0044] In another embodiment, the slide rail 11 is an I-shaped rail. The auxiliary limiting member 25 further includes a second limiting roller 252.

[0046] In one embodiment, to streamline the structure, the driving of each winding belt 263 also adopts a synchronous method. The lifting adjustment member 26 includes two second right-angle commutators 261. The two second right-angle commutators 261 are arranged in parallel at intervals, and the longitudinal rotating shafts of the two second right-angle commutators 261 are linked and are both driven by the lifting adjustment motor 28. The two ends of the transverse rotating shafts of the two second right-angle commutators 261 are respectively installed with winding discs 262, and each winding disc 262 is provided with its own winding belt 263. Since the application of the strap suspension seat 27 belongs to the prior art, the specific usage methods of it and the lifting adjustment member 26 will not be elaborated here. In addition, it should be noted that the right-angle commutator adopted in this embodiment is also the prior art, and its specific internal structure will not be elaborated either.
[0047] In addition, the driving motor 23 and the lifting adjustment motor 28 are arranged vertically one above the other to save space. At the same time, to reduce wiring, on the basis of the above embodiment, the power supply method of a trolleybus can be adopted. The track group 1 further includes a trolley wire 12 laid along the slide rail 11. The training mobile vehicle 2 further includes a current collector 29. The current collector 29 supplies power to the driving motor 23 and the lifting adjustment motor 28 and is provided with electric brushes that fit and move along the trolley wire 12. Since the power supply method of a trolleybus is the prior art and the present invention only applies it, which does not belong to the technical improvement points of the present invention, its specific implementation principle will not be elaborated here. Of course, in other embodiments, it is also possible to adopt the method of laying wires along the slide rail 11 to form a wired connection method and be equipped with a drag chain for storing wires.
[0048] On the basis of the above embodiments, a helicopter departure platform 3 is further included. And to provide a more realistic simulation scenario, the helicopter departure platform 3 simulates the structure of a helicopter cabin and is provided with a rear departure opening 31 and a side hatch departure opening 32. There are two sets of the track group 1 and the training mobile vehicle 2, which are respectively arranged at the rear departure opening 31 and the side hatch departure opening 32, so that the training personnel can carry out simulation training for rear departure or side hatch departure on different training mobile vehicles 2. In addition, to simulate the parachute jump training at a moving height, a training building can be arranged at the bottom of the helicopter departure platform 3, so as to increase the height of the helicopter departure platform 3.
[0049] On the basis of the above embodiments, to improve the safety level and prevent the training mobile vehicle 2 from running out of the slide rail 11, a limiting structure is provided, including buffer members arranged at the front and rear ends of the track, limit detectors arranged at the front and rear ends of the track, and stroke limiters arranged on both sides of the training mobile vehicle 2. The buffer members can adopt spring structure buffer members or hydraulic ones. The limit detectors can adopt proximity switches, and the stroke limiters can adopt travel switches. It should be noted that the above buffer members, limit detectors and stroke limiters all adopt existing electronic components, which are applications of existing technologies in the field of tracks or mobile vehicles, and will not be elaborated here.
[0050] The parachute jump training device provided by the present invention adopts a training mobile vehicle 2 with a four-wheel drive structure, which can realize the synchronous rolling of the four moving wheels 22. Even at an uneven slide rail 11, there will be no problem of instant serious stall when individual wheels are separated from the slide rail 11, and it is not easy to have a large differential speed between the left and right sides. In addition, combined with the auxiliary limiting member 25, the grasping degree of the training mobile vehicle 2 on the slide rail 11 is further improved, thereby greatly improving the moving stability and safety of the training mobile vehicle 2. Furthermore, the training mobile vehicle 2 can adapt to a higher-speed driving state and can provide a faster training scenario for the training personnel.
[0051] The above has described the present invention in an exemplary manner with reference to the drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
