The safety tongs triggering device for the vertical elevator comprises an acceleration monitoring mechanism and a brake triggering mechanism, and the acceleration monitoring mechanism comprises a bottom plate, at least one guide column installed on the bottom plate, a compression spring arranged on the guide column in a sleeving mode and a heavy block; the lower end of the compression spring is contacted with the bottom plate, and the upper end is contacted with the weight; one end of an inhaul cable of the control brake cable is fixed to the heavy block, and the other end of the inhaul cable of the control brake cable is fixed to the brake triggering mechanism; the brake triggering mechanism is installed on a brake triggering mechanism support, the brake triggering mechanism support is installed on the lift car, and after the brake triggering mechanism is triggered, the speed limiter-safety tongs linkage mechanism is triggered to act. The safety tongs can be triggered to act when the elevator car tends to slip downwards in an accelerated mode, braking is achieved under the condition that the descending speed of the elevator car is low, personnel and goods in the elevator car are better protected, and the safety performance of an elevator is improved.

    本发明公开的一种垂直电梯用安全钳触发装置,包括加速度监控机构和制动触发机构,其中,加速度监控机构包括:底板,安装在所述底板上的至少一导向柱,套在导向柱上的压缩弹簧和重块;压缩弹簧的下端与底板接触,上端与所述重块接触;控制闸线,控制闸线的拉索的一端固定在重块上,另一端固定在制动触发机构上;制动触发机构安装在一制动触发机构支架上,制动触发机构支架安装在轿厢上,制动触发机构触发后,进而触发限速器‑安全钳联动机构动作。本发明能够在电梯轿厢有加速向下溜车倾向时,就能触发安全钳动作,在轿厢下行速度还很低的情况下实现刹车,更好的保护了电梯轿厢内的人员和货物,提升电梯安全性能。
