The invention belongs to the technical field of elevator overspeed detection devices, and discloses an elevator overspeed detection device and a working method thereof.The elevator overspeed detection device comprises an elevator car body, brakes are fixedly installed on the two sides of the bottom end of the elevator car body correspondingly, braking assemblies are arranged in the brakes, and sliding rails are slidably installed on one sides of the two brakes correspondingly; the sliding rail is fixedly installed at the bottom end of the top plate, the speed adjusting structure is arranged at the top end of the top plate, the rope is arranged on the outer wall of the speed adjusting structure, and through mutual cooperation of the braking assembly and the speed limiting assembly, when an elevator breaks down and the rope is broken, the elevator car body can be braked through the braking assembly firstly, and then the elevator car body is controlled to slide downwards through the speed limiting assembly; the lift car body slowly slides to the bottom, the problem that the rescue waiting time is long due to the fact that passengers are possibly trapped in the lift car body due to emergency braking of the lift car body is solved, the rescue waiting time is shortened, rescue workers can conveniently arrive at a rescue site, and the workers can conveniently escape from the trapped passengers.

    本发明属于电梯超速检测装置技术领域,且公开了一种电梯超速检测装置及其工作方法,包括轿厢主体,轿厢主体底端的两侧皆固定安装有制动器,制动器的内部设置有制动组件,两个制动器的一侧均滑动安装有滑轨,滑轨固定安装在顶板的底端,顶板的顶端设置有调速结构,调速结构的外壁设置有绳索,通过制动组件与限速组件的相互配合,在电梯发生故障绳索断裂时,可先通过制动组件使轿厢主体刹停,再通过限速组件来控制轿厢主体向下滑动,使轿厢主体缓慢滑动至底部,避免了轿厢主体的紧急制动可能会导致乘客被困在轿厢主体内,导致等待救援时间较长的问题,减少了等待救援的时间,方便救援人员到达救援地点,便于人员脱困。
