Abstract

The present invention provides an overspeed governor assembly and an elevator system, wherein the overspeed governor assembly includes: a fixed shaft; a sheave, the sheave being arranged on the fixed shaft and rotatable on the fixed shaft; a core ring arranged on one side of the sheave on the fixed shaft and associated with a safety device, and a locking mechanism including a plurality of rockers, each rocker including a pivotally connected To the first end of the sheave and the second end connected to the respective rollers, the plurality of rockers are connected by connecting rods so that the plurality of rockers are synchronized, and the plurality of rockers can be Pivoting between a first position where the respective rollers are separated from the core ring and a second position where the respective rollers are engaged with the core ring, in which the respective rollers rotate as the sheaves rotate the core ring, thereby triggering the mounting device.

Description

technical field [0001] The present invention relates to the technical field of elevator overspeed governors, and more specifically, the present invention relates to a car-mounted elevator overspeed governor and an elevator system having the same. Background technique [0002] With the development of the governor assembly technology for elevators, the new car-mounted governor assembly (CMG CarMounted Governor) has been more widely used. Compared with the design of the traditional machine-room or machine-room-less speed governor assembly in which the speed governor is installed on the top of the hoistway, the car-mounted speed governor assembly is installed on the elevator car and moves up and down with the car. The structure of the car-installed overspeed governor assembly is more compact, which is suitable for the situation where the hoistway space is limited. A car-mounted speed governor assembly is disclosed in US Patent Publication No. US2013 / 0098711A1 published by Aguad...
