The invention discloses a steady-speed lowering winch and relates to the technical field of offshore evacuation systems. The problems that an existing winch cannot be used without power, the occupied space is large, and the torque is small, so that the whole evacuation system is poor in working reliability and low in efficiency are solved. The winch comprises a hand wheel, a roller backstop, a gear shifter, a three-stage planetary gear reducer, a roller, a friction type centrifugal speed governor, a motor, a left support, a right support and a winch base. The winch has a stable-speed lowering function, a braking function during lowering, a motor lifting function and a manual lifting function; three-stage planetary gear transmission is adopted, the transmission ratio is large, and the torque is large; the operation is simple, and the shift among gears can be realized only by rotating the control handle; the winch adopts a coaxial concealed arrangement mode, and the speed reducer and the gear shifter are concealed in the winding drum, so that the structure of the winch is compact, and the requirement of a working condition with a narrow space can be met.

    一种稳速下放绞车,涉及海上撤离系统技术领域。本发明解决了现有绞车不能在无动力下使用、占用空间大、扭矩小而导致的整个撤离系统工作可靠性差且效率低的问题。所述绞车包括手轮、滚柱逆止器、换挡器、三级行星齿轮减速器、滚筒、摩擦式离心限速器、电机、左支架、右支架和绞车基座。本发明所述绞车具有稳速下放功能、下放时的制动功能、电机提升功能和手动提升功能;所用三级行星齿轮传动,传动比大,扭矩大;操作简单,只需转动操纵手柄即可实现个档位之间的变换;绞车采用同轴内藏式布置方式,减速器和换挡器内藏于卷筒中,使绞车结构紧凑,可以满足空间狭小的工况的要求。
