The bidirectional speed limiter comprises a rope wheel, a transmission mechanism, a main shaft, a speed detection mechanism, an action mechanism, a rope clamping device, a spring and an electric switch, the speed detection mechanism comprises an upper platform, a lower platform, a swing arm, a heavy block and a swing connecting rod; when the elevator descends, the rope wheel drives the main shaft to rotate in the first direction, the lower platform provides positive compensation for the lower platform relative to the rotating direction of the upper platform, and the positive compensation is used for applying upward force to the lower platform; when the speed of the elevator reaches a first descending overspeed V1 ', the action mechanism triggers the electric switch to act, and when the speed of the elevator reaches a second descending overspeed V2 ', the action mechanism triggers the rope clamping device to act; when the elevator ascends, the rope wheel drives the main shaft to rotate in the second direction, the lower platform provides negative compensation for the lower platform relative to the rotating direction of the upper platform, and the negative compensation is used for applying downward force to the lower platform; and when the speed of the elevator reaches the first ascending overspeed V1, the action mechanism triggers the electric switch to act.
本发明公开了一种电梯双向限速器,包括绳轮、传动机构、主轴、速度检测机构、动作机构、夹绳装置、弹簧和电气开关;所述速度检测机构包括上平台、下平台、摆臂、重块和摆动连杆;当电梯下行时,绳轮带动主轴沿第一方向旋转,下平台相对上平台的转动方向对下平台提供正补偿,正补偿的作用为对下平台施加向上的力;当电梯速度达到下行第一超速速度V1’时,动作机构触发电气开关动作,当电梯速度达到下行第二超速速度V2’时,动作机构触发夹绳装置动作;当电梯上行时,绳轮带动主轴沿第二方向旋转,下平台相对上平台的转动方向对下平台提供负补偿,负补偿的作用为对下平台施加向下的力;当电梯速度达到上行第一超速速度V1时,动作机构触发电气开关动作。
