[0002] With the development of aviation technology, glider as a kind of powerless aircraft that can fly in the air for a long time, has been widely used in military reconnaissance, weather observation, sports and other fields. However, the traditional glider take-off mode usually relies on natural wind power or high-altitude release with other powered aircraft, which not only limits the use scene of glider, but also increases the operation complexity and cost.
[0003] In order to solve the above problems, there are many types of glider ejector in the market, which can help glider reach take-off speed quickly by converting mechanical energy into kinetic energy. The existing glider ejector is mainly fixed ejector. Although this kind of device has simple structure and good stability, it occupies large area and is inconvenient to move.
[0004] Therefore, it is imperative to redesign a glider ejector. UTILITY MODEL CONTENT
[0005] In view of the defects of the prior art, the utility model provides a glider ejector, which aims to solve the problems of inconvenient movement and complex operation of the glider ejector in the prior art.
[0006] To achieve the above purpose, the technical scheme adopted by the utility model is: a glider ejector, comprising a truck head and a semitrailer mounted behind the truck head, a folding pressure bearing mechanism rotatingly matched with the tail of the semitrailer, a folding launching rack mechanism slidingly connected to the folding pressure bearing mechanism, a folding launching runway mechanism arranged on one side behind the folding launching rack mechanism and a lead block placed on the folding launching rack mechanism, the folding launching runway mechanism comprising a runway assembly and a pulley arranged at the highest point of the runway assembly, the lead block is connected with the glider placed on the runway assembly through the pulley by a traction rope, when the folding launching rack mechanism is folded away from the runway assembly by a plurality of folding drive assemblies, the lead block falls down by its own gravity, thereby pulling the glider to take off.
[0007] Based on the above, the glider ejector has the advantages of solving the problems of inconvenient movement, insufficient structural strength and complex operation of the glider ejector in the prior art, mainly embodied in:
[0008] 1. The utility model discloses a glider launching device integrated on a semitrailer, which realizes high mobility and rapid deployment capability of the device, and can be used flexibly in different sites and environments. During transportation, the folding pressure bearing mechanism is folded along the pressure bearing plate, and the folding drive motor of the two folding drive assemblies of the folding launching rack mechanism supports the whole folding launching rack mechanism horizontally on the semitrailer. The runway rack of the folding launching runway mechanism is folded on the vertical rack along the output end of the runway expansion motor, and the glider is placed horizontally on the runway rack. As a result, the whole launching device is compactly folded, greatly reducing the transportation space and facilitating long-distance transportation and rapid deployment on site, thereby solving the problem of inconvenient movement of the glider launching device in the prior art.
[0009] 2. The utility model adopts lead blocks with a certain weight as the traction source. During launching operation, the folding launching rack mechanism is folded, causing the lead blocks to fall vertically and rapidly onto the folding pressure bearing mechanism, thereby pulling the glider to accelerate along the runway rack. When the glider is about to run out of the runway rack, it passes the position of the photoelectric sensor. After detecting the passing of the glider, the photoelectric sensor sends a signal to the control system on the vehicle. The control system then controls the electronic buckle to open through wireless signal, causing the glider to separate from the traction rope and take off smoothly. The whole process is automatically operated, which greatly reduces the operation complexity compared with the prior art.
