The speed governor comprises a base frame, a wheel shaft on the base frame and a rope wheel rotationally installed on the wheel shaft, the wheel shaft is coaxially provided with a brake disc, the rope wheel is provided with a centrifugal mechanism, the centrifugal mechanism comprises two centrifugal swing arms and a connecting rod arranged between the two centrifugal swing arms, a speed regulating assembly is arranged between the centrifugal swing arms and the rope wheel, and the two centrifugal swing arms are rotationally installed on the rope wheel. The two sides of the brake disc are respectively located; the speed regulation assembly is used for regulating the speed limit of the speed governor, brake bumps are respectively arranged corresponding to the two centrifugal swing arms, and the brake bumps are arranged on the rope wheel through pin shafts and are in running fit with the pin shafts; the centrifugal swing arm abuts against the pin shaft and is in linkage with the brake protruding block through a linkage pin. When the speed governor is in an overspeed state, the centrifugal swing arm is separated from the pin shaft and is in linkage with the brake protruding block through the linkage pin to be attached to the brake disc, and rope wheel braking is achieved. When the speed governor is in an overspeed state, the centrifugal swing arm is directly linked with the brake protruding block through the linkage pin, and the brake protruding block is attached to the brake disc to achieve quick response to rope wheel braking.

    本发明涉及限速器,包括基架、基架上的轮轴和转动安装于轮轴的绳轮,轮轴同轴设有制动盘,绳轮设有离心机构,离心机构包括两离心甩臂和设于两离心甩臂之间的连杆,离心甩臂与绳轮之间设有调速总成,两离心甩臂转动安装于绳轮,且分别位于制动盘的两侧;调速总成用于调节限速器的限速,对应于两离心甩臂分别设有制动凸块,制动凸块通过销轴安装于绳轮,且转动配合于销轴;离心甩臂抵接于销轴,并与制动凸块通过联动销联动;当限速器处于超速状态,离心甩臂脱离销轴并通过联动销联动制动凸块贴合制动盘,以实现绳轮制动。本发明限速器在超速状态下,离心甩臂直接通过联动销联动制动凸块,制动凸块贴合制动盘实现快速响应绳轮制动。
