The first roller and the second roller are coupled by a belt or a gear, the driving part 300 includes a second bracket 330, and the first roller and the second roller are fixed on the second bracket 330 and can rotate on the second bracket 330.
In the middle of current technique, the rope line cover is on the center pin, can transport the eminence with the rope through the people, under recent circumstances, like the eminence operation, the fire hazard, the condition such as flood, unmanned aerial vehicle transportation has been adopted, if send the one end of rescue rope to eminence or other places through unmanned aerial vehicle, in this time, when rope between gyro wheel and the unmanned aerial vehicle ties up (unmanned aerial vehicle will bear great rope pulling force in this time), the great pressure of rope can be sensed to the sensor, central processing unit is carried to this pressure data, central processing unit increases the release rate of rope line through the rotational speed of controlling first gyro wheel and second gyro wheel, and then reduce the pulling force of the rope that unmanned aerial vehicle received, make the rope can be safe send the destination to.
In the middle of the prior art, the rescue rope will bear great power, so the rope will design enough thick, but increased the weight of rope simultaneously again, exceeded unmanned aerial vehicle's maximum load, influenced the rescue effect or can't make the rescue accomplish smoothly. Therefore, in an improved embodiment, the rescue rope is designed into three sections, and the corresponding central rotating shaft is also designed into three sections, as shown in fig. 2, the central rotating shaft 110 includes a first rotating shaft 111, a second rotating shaft 112, and a third rotating shaft 113, the first rotating shaft 111 and the second rotating shaft 112 are coaxial and adjacent, the second rotating shaft 112 and the third rotating shaft 113 are coaxial and adjacent, a cross-sectional diameter of the first rotating shaft 111 (as viewed in a cross-sectional view taken along a plane perpendicular to a drawing direction in fig. 2) is smaller than that of the second rotating shaft 112, and a cross-sectional diameter of the second rotating shaft 112 is smaller than that of the third rotating shaft 113. The cord 600 includes a first cord wound on the first shaft 111, a second cord wound on the second shaft, and a third cord wound on the third shaft, wherein the start end of the first cord (the end that is released first when the cord is released) is connected to the end of the second cord (the end that is released last when the cord is released), the start end of the second cord is connected to the end of the third cord, the tensile strength of the first cord is greater than that of the second cord, and the tensile strength of the second cord is greater than that of the third cord. When the first rope is completely wound on the first rotating shaft, the outer contour formed by winding (the diameter of the outer contour of the first rotating shaft is increased when the first rope is completely wound on the first rotating shaft) is basically equivalent to that of the second rotating shaft, and when the second rope is completely wound on the second rotating shaft, the outer contour formed by winding is basically equivalent to that of the third rotating shaft. The first support 200 is provided at both sides thereof with rollers 210, which can move the first support when needed. The third rope line with thinnest and least strength is wound on the third rotating shaft. When the rescue begins, release the third rope at first, the origin of third rope is transported to the destination by unmanned aerial vehicle, because the sufficient light of third rope, it can be transported by whole, and the length of third rope is enough long to make the origin transport by unmanned aerial vehicle to the destination when, the second rope does not release. When the second rope is completely released, the destination person operates the second rope, releases the third rope and finally enables the starting end of the third rope to reach the destination. Under one scene, the starting end of the rope can be transported to a high-place dangerous person under the flood or fire, and under some scenes, the rope can also be used for normal construction, and the starting end of the rope can be transported to the high place or can pass through a certain position of the high place.
