The invention discloses a double-rotor emergency rescue unmanned helicopter in the technical field of unmanned aerial vehicles, which comprises an unmanned helicopter body, a moving mechanism is mounted at the lower end of the unmanned helicopter body, and four groups of rope winding mechanisms are mounted on the moving mechanism. The moving mechanism is used for adjusting transverse spacing or longitudinal spacing of the four groups of rope winding mechanisms, and the rope winding mechanisms are used for connecting and fixing a loading platform or a manned stretcher; according to the scheme, the anti-winding mechanism is installed between the two longitudinal rope winding mechanisms, the situation that the longitudinal distance between the two longitudinal rope winding mechanisms is too close, and in the flight process, two adjacent cable sets are prone to being wound together under the influence of wind power is avoided, and through the structural arrangement of the anti-winding mechanism, the winding speed of the cable is increased. The distance between the two sets of cables can be kept all the time, and the situation that due to the fact that the cables are wound, the carrying platform or the manned stretcher rotates in the flying process in the air, and transported articles or people fall off to cause accidents is avoided.
本发明公开了无人机技术领域的一种双旋翼应急救援无人直升机,包括无人直升机本体,所述无人直升机本体的下端安装有移动机构,所述移动机构上安装有四组绳索收卷机构,所述移动机构用于对四组绳索收卷机构进行横向间距或纵向间距调节,所述绳索收卷机构用于对载物平台或是载人担架连接固定;本方案通过防缠绕机构安装在纵向的两组绳索收卷机构之间,避免纵向的两组绳索收卷机构之间的纵向间距过近,在飞行过程中,相邻的两组线缆在风力的影响下容易缠绕在一起,通过防缠绕机构的结构设置,可以始终保持两组线缆之间的间距,避免线缆之间发生缠绕,导致载物平台或是载人担架在空中飞行过程中发生旋转,导致运输物品或人员掉落发生意外。
