Deviation from rail detection device of elevator

摘要

In the deviation from rail detection device of the elevator, the 1st and 2nd electric conduction line (1,2), the ascent and descent body (20) the hoistway (11) it is arranged parallel into ascent and descent direction inside. The ascent and descent body (20), the 1st and 2nd electric conduction line (1,2) the 1st and 2nd contact which contacts respectively (3,5) is loaded the ascent and descent body (20) the guide rail (22) from by coming off. The 1st electric conduction line (1) makes plus electric potential, the 2nd electric conduction line (2) makes ground electric potential. The sensing station (7), the ascent and descent body (20) the guide rail (22) from comes off the 1st contact (3) and the 1st electric conduction line (1) with the presence of continuity and detects how high.
