The invention relates to the technical field of elevator braking, in particular to a double-insurance elevator safety system which comprises an elevator host encoder and a braking connecting rod mechanism, and the braking connecting rod mechanism comprises sliding blocks arranged on two safety tongs and a braking connecting rod arranged between the two sliding blocks; the elevator host encoder is used for acquiring the elevator host rotating speed; an electromagnet is further included, the electromagnet comprises a telescopic sliding rod, and the free end of the sliding rod is connected with the braking connecting rod mechanism; in the initial state, the sliding rod stretches out, and the electromagnet is used for controlling the sliding rod to contract when the rotating speed of the elevator host exceeds a preset speed threshold value. By the adoption of the scheme, various braking insurance can be provided for operation of the elevator, and the elevator car is prevented from descending overspeed.

    本发明涉及电梯制动的技术领域,具体为一种双保险的电梯安全系统,包括电梯主机编码器和制动制动连杆机构,制动制动连杆机构包括两安全钳上设置的滑块,以及两滑块之间设置的制动连杆;电梯主机编码器用于获取电梯主机转速;还包括电磁铁,电磁铁包括能够伸缩的滑动杆,滑动杆的自由端与制动制动连杆机构连接;初始状态下,滑动杆伸出,电磁铁用于根据当电梯主机转速超过预设的速度阈值时,控制滑动杆收缩。采用本方案,能够为电梯的运行提供多种制动保险,防止电梯轿厢超速下行。
