The bidirectional double-speed governor comprises a rope wheel, a main shaft, a base, a speed detection mechanism and a brake mechanism, the rope wheel is supported on the main shaft, the rope wheel drives the main shaft to rotate together, the main shaft is rotatably fixed to the base through a bearing, the speed detection mechanism can trigger the brake mechanism at a preset speed, and the brake mechanism is driven by the speed detection mechanism to rotate. The brake mechanism is used for braking the speed governor rope; according to the speed limiter, only one speed detection mechanism is used for achieving different triggering speeds in the scene that the ascending rated speed of the high-speed elevator is larger than the descending rated speed, and the size and cost of the speed limiter are greatly reduced; meanwhile, by further changing the setting of the elastic piece, different overspeed switch second triggering speeds Vu1 can be set under the condition that parts are not replaced so as to cope with elevators with different ascending rated speeds, and the speed limiter is more universal.
本发明公开了一种电梯双向双速限速器,包括绳轮、主轴、基座、速度检测机构和制动机构,所述绳轮支撑在主轴上,所述绳轮带动主轴一起旋转,所述主轴通过轴承可旋转地固定在基座上,所述速度检测机构在预设速度下可触发制动机构,使制动机构对限速器绳进行制动;本发明仅用一套速度检测机构即实现了高速电梯上行额定速度大于下行额定速度场景下的不同触发速度,大大减小了限速器的体积和成本,同时通过进一步改变弹性件的设定可以在不更换部件的情况下设置不同的超速开关第二触发速度Vu1以应对不同上行额定速度的电梯,使限速器更通用化。
