Specific embodiment

With reference to the accompanying drawing, specific embodiment of the present utility model is described in further detail.

A kind of transmitting unmanned plane drum drive, it is characterised in that: including drum drive 1, the drum driven Mechanism 1 includes driving motor 2, roller 3 and rope, and the driving motor 2 drives roller 3, and 3 surface of the roller edge is axially arranged with Helicla flute 7, the rope are wrapped on helicla flute 7, and the both ends of rope are stretched out from the starting point of helicla flute 7 and clearing end respectively, In favor of driving roller just by driving motor by being fixedly connected after rope ends intersection with the front-end and back-end of slide trolley Turn and reversion, a drawing one time on guide rail of drive slide trolley realize the transmitting of unmanned plane, and recyclable slide trolley, For use next time.

Rope described in the utility model includes driving rope 4 and recycling rope 5, and the roller 3 is equipped with pressing plate 6, described The starting point of helicla flute 7 and clearing end are separately installed with driving rope 4 and recycling rope 5,4 lower end of driving rope and recycling 5 lower end of rope is separately fixed on roller 3 and compresses through pressing plate 6, and the driving rope 4 and recycling rope 5 are respectively into roller 3 Heart winding, 4 upper end of driving rope and recycling 5 upper end of rope are pierced by that roller 3 is cross-shaped to be placed on the outside of roller 3 respectively, institute It states pressing plate 6 to be fixedly connected with roller 3, in favor of needing biggish speed when unmanned plane, i.e. slide trolley needs biggish pulling force When, trolley is pulled and withdrawn by fixing two ropes, and the driving force of driving motor driving roller can be directly passed to drive On running rope rope and recycling rope, the emission rate of slide trolley is controlled.

Drum drive 1 described in the utility model further includes rolling stand, and rolling stand includes left support 8 and right support 9, left support 8, roller 3 and right support 9, the roller 3 and driving motor are successively arranged on the output shaft of the driving motor 2 Output shaft is fixedly connected, and the 3 two sides warp beam of roller, bearing are connected with left support 8 and right support 9, in favor of passing through roller Drum drive can be fixed up to support roller by left support and right support by bracket, increase roller drive The stability of motivation structure and the safety of transport.

Such as attached drawing, roller can be welded by aluminum, and circumferencial direction processes helical groove structure, and roller is driven by driving motor Dynamic, roller can be fixedly connected by shaft coupling with the output shaft of driving motor, and when in use, drum drive is placed on On trailer, positioned at the middle and lower part of unmanned plane launcher beam, by left support lower end and right support lower end by bolt, nut with Trailer chassis is fixedly connected, and a rope or two ropes can be used in the utility model, when slide trolley need power not When big, a rope can be used, the centre of helicla flute is wrapped in the middle part of rope, then rope ends are rotated to helicla flute both ends, It is stretched out respectively from the starting point of helicla flute and clearing end, the both ends of rope may be defined as driving end and recovery end, drives end and returns Receiving end is fixedly connected after intersecting with the front-end and back-end of coaster；When the power that slide trolley needs is larger, i.e., unmanned plane needs very Fast speed, at this point it is possible to which two ropes are arranged, respectively driving rope and recycling rope, driving rope can with recycling rope It is mounted on starting point and the clearing end of helicla flute, and is compressed by pressing plate, then drives rope and recycling rope respectively to spiral The rotation of slot centre, then driving rope and recycling rope are pierced by after roller intersects and the front-end and back-end of slide trolley are fixed and connected It connects；When slide trolley, which needs to advance, obtains speed, twined at this point, the circle number that driving rope is wrapped on roller is less than recycling rope The circle number being wound on roller, in this way in driving motor driving roller rotation, driving rope pulls slide trolley as roller revolves Turn, circle number of the rope on roller is driven to increase, recycling rope constantly puts rope, and circle number is reduced, and when slide trolley is recovered, drives Dynamic motor driven roller rotates round about, recycles rope force at this time, slide trolley is pulled to return, and recycles rope with roller Rotation is recycled circle number of the rope on roller and is increased, and driving rope is reduced, and realizes the withdrawal of slide trolley, the utility model Used roller can reduce rotary inertia, improve the utilization rate of drive system；By driving motor drive roller rotate forward and The transmitting and recycling of coaster are realized in reversion, and fast response time, accumulation of energy is stable, power is sufficient, and structure is simple, at low cost, operation It is simple and reliable.
