The invention discloses a trigger device and a trigger method for a free fall test of progressive safety tongs of an elevator, and relates to the technical field of elevator testing, the trigger device for the free fall test of the progressive safety tongs of the elevator comprises a pulley assembly, a traction rope, a fixing part, a sleeve and a blocking part; the pulley assembly comprises an upper pulley and a lower pulley; the traction rope is arranged between the upper pulley and the lower pulley in a sleeving manner and is provided with a first traction section; the fixing part is fixedly arranged on the first traction section so as to move up and down along with the traction rope, and the fixing part is used for being fixed to one end of the lifting rod; the sleeve sleeves the first traction section and is fixed with the traction rope through static friction force, the sleeve is positioned at the lower end of the fixed part, and a distance is reserved between the sleeve and the lower end of the first traction section; and the blocking part is positioned below the sleeve, is limited and is used for blocking the sleeve when the sleeve moves downwards along with the first traction section. According to the technical scheme, the problem that potential safety hazards exist due to the fact that an existing device needs to adjust the sleeve at high altitude can be solved.
本发明公开了一种电梯渐进式安全钳自由落体试验触发装置和触发方法,涉及电梯测试技术领域,电梯渐进式安全钳自由落体试验触发装置包括滑轮组件、牵引绳索、固定部、套筒和阻挡部;滑轮组件包括上滑轮和下滑轮;牵引绳索套设在上滑轮和下滑轮之间,牵引绳索具有第一牵引段;固定部固定设置在第一牵引段,以能够随同牵引绳索上下活动,固定部用以与提拉杆的一端固定;套筒套设在第一牵引段且与牵引绳索之间通过静摩擦力固定,套筒位于固定部的下端,且与第一牵引段的下端之间预留一间距;阻挡部位于套筒的下方且被限位,用以在套筒随同第一牵引段向下时,抵挡套筒。本发明提供的技术方案能够改善现有装置需要在高空调整套筒,存在安全隐患的问题。
