The invention belongs to the field of elevators, solves the problem that a trigger plate is easy to damage when used for detection, and relates to a self-inspection type elevator speed governor. Comprising a rope wheel, a throwing piece which is connected to the rope wheel and can expand outwards through centrifugal force when the rope wheel rotates at an overspeed, a trigger plate which is arranged on the outer side of the throwing piece and is used for being toggled when the throwing piece expands outwards, a switch beating plate which is connected with the trigger plate, and an electrical switch which can be closed by the switch beating plate, and a pushing mechanism is arranged on the throwing piece. The triggering plate is provided with a first triggering part, the triggering plate can be driven to swing towards the center of the rope wheel so that the first triggering part can touch the pushing mechanism during self-inspection, the stopping plate and the triggering plate are connected in a relative sliding mode, the stopping plate is provided with a stopping head, and the stopping head protrudes out of the surface, facing the pushing mechanism, of the first triggering part; and the throwing sheet is configured to expand outwards when the pushing mechanism is pushed by the blocking head. The beneficial effect is that the trigger plate is not easy to damage in the detection process.
本发明属于电梯领域,解决触发板用于检测时易损坏问题,涉及一种自检型电梯限速器,包括绳轮、连接在绳轮上且能够在绳轮超速旋转时利用离心力外展的甩片、设置于甩片外侧的用于被甩片外展时拨动的触发板、与触发板连接在一起的开关打板以及能够被开关打板关闭的电气开关,甩片上设置有推动机构,触发板上设置有第一触发部,触发板能够被动向绳轮中心摆动以在自检时第一触发部能够触碰推动机构,还包括阻拦板,阻拦板与触发板之间相对滑移地连接,阻拦板具有阻拦头,阻拦头突出于第一触发部迎向推动机构的表面,甩片配置为在推动机构被阻拦头推动时外展。有益效果是触发板不易在检测过程中损坏。
