The invention relates to the technical field of rescue escape devices, and particularly discloses a novel safety rapid drop device. The device comprises a shell, a central shaft, a winding drum and atraction rope wound on the winding drum; the central shaft is rotationally arranged in the shell; the winding drum is rotationally arranged on the central shaft; the device further comprises a speed reduction mechanism, a speed limiting mechanism and a recovery mechanism for recovering the traction rope; the speed reduction mechanism comprises two sets of planetary mechanisms respectively arrangedon two sides of the winding drum; the planetary mechanisms comprise left sun gears, left planet carriers, left planet gears, right sun gears, right planet carriers and right planet gears; the right sun gears are fixedly arranged on the shell; the left sun gears are fixedly arranged on the central shaft; a plurality of connecting rods are fixedly arranged between the left planet carriers and the right planet carriers; and the connecting rods penetrate through the winding drum. According to the device, the speed reduction ratio design and the overall stress are more reasonable, and the safety design coefficient is improved.
本发明涉及救援逃生装置技术领域,具体公开了一种新型安全速降装置,包括外壳、中心轴、卷筒和卷绕在卷筒上的牵引绳,中心轴可转动地设置于外壳内,卷筒可转动地设置于中心轴上;还包括减速机构、限速机构和用于回收牵引绳的回收机构,减速机构包括分别设置于卷筒两侧的两套行星机构,行星机构包括左太阳轮、左行星轮架、左行星轮、右太阳轮、右行星轮架和右行星轮,右太阳轮固定设置在外壳上,左太阳轮固定设置于中心轴上,左行星轮架和右行星轮架之间固定设置有若干连接杆,连接杆穿过卷筒。本发明的减速比设计和整体受力更加合理,并且本发明提高了安全设计系数。
