The invention discloses a safety tongs triggering system for a vertical elevator. The safety tongs triggering system comprises a speed limiter, a steel wire rope for the speed limiter, an electrical switch and a car side safety tongs. The steel wire rope counterweight side connecting piece is connected with the counterweight side of the steel wire rope for the speed limiter, and the steel wire rope counterweight side connecting piece is connected with the counterweight; the steel wire rope lift car side connecting piece is connected with the lift car side of the steel wire rope for the speed limiter, and the steel wire rope lift car side connecting piece is connected with a handle in the lift car side linkage mechanism; and the electric switch is locked and attached to the lift car side linkage mechanism and is positioned below the steel wire rope lift car side connecting piece. According to the safety tongs triggering system for the vertical elevator, a tensioning device is omitted, the length of the steel wire rope for the speed limiter is halved, the steel wire rope does not need to penetrate through the whole hoistway, the design of the safety tongs triggering system is optimized, space is reserved for configuration of other elevator suspension parts, and the safety tongs triggering system can be suitable for hoistways with smaller pit space; and meanwhile, the manufacturing cost of the safety tongs triggering system is greatly reduced.

    本发明公开的一种垂直电梯用安全钳触发系统,包括:限速器、限速器用钢丝绳、电气开关、轿厢侧安全钳;其特征在于,还包括:与限速器用钢丝绳的对重侧连接的钢丝绳对重侧连接件,该钢丝绳对重侧连接件与对重连接;与限速器用钢丝绳的轿厢侧连接的钢丝绳轿厢侧连接件,该钢丝绳轿厢侧连接件与轿厢侧联动机构中的手柄连接;电气开关锁附在轿厢侧联动机构上并位于钢丝绳轿厢侧连接件的下方。本发明的垂直电梯用安全钳触发系统取消了张紧装置,限速器用钢丝绳长度减半,且钢丝绳无需贯穿整个井道,优化了安全钳触发系统的设计,为其它电梯悬挂部件配置让出了空间,并可适用在更小底坑空间的井道内,同时大幅度降低了安全钳触发系统的制造成本。
