The invention relates to a duplex brake elevator speed governor and a testing mechanism thereof. Under the action of centrifugal force generated when an elevator stalls, two throwing pieces of the elevator speed governor rotate around a rotating shaft, then an eccentric wheel is driven to deflect, the eccentric wheel makes contact with and is meshed with a brake disc to achieve braking of a rope wheel, the braking effect is good, due to the double-throwing-piece linkage structure, the braking effect is good, and the working safety and reliability are higher. Besides, the remote testing mechanism is mainly used for testing the working effectiveness of the elevator speed governor by pushing a transverse shaft to enable the eccentric wheel to deflect on the basis of a remotely controllable electromagnetic magnet, and is high in operability and convenient to control.

    本发明涉及一种双联制动电梯限速器及其测试机构,电梯限速器在电梯失速时所产生的离心力作用下,两个甩片绕转动轴转动,进而带动偏心轮发生偏转,偏心轮与制动盘接触啮合进而实现对于绳轮的制动,制动效果好,而且双甩片联动的结构使得制动效果不但好,而且工作的安全性和可靠性也更高。另外,本申请的远程测试机构,主要就是基于一远程可控的电磁吸铁,结合推动横轴使得偏心轮发生偏转来测试电梯限速器的工作有效性,可操作性强,且便于进行控制。
