The utility model discloses a transmission device for a depth indicator of a mine hoist, comprising a box body and an input shaft and output shafts arranged in the box body, and a bevel gear pair consisting of three bevel gears is arranged in the box body, wherein a shaft of one bevel gear is used as the input shaft; shafts of the other bevel gears are used as the output shafts; one output shaft is connected with the depth indicator, and the other is provided with a rotating speed signal coder; and the transmission ratio of the three bevel gears is 1:1:1. The utility model can convert the rotary power of a spindle into the electrical signal, and then feeds back in an electric control cabinet; when the rotating speed of the spindle is over-fast or over-slow, the electrical signal fed back by the coder is transmitted to an electric control pivot system and then compared to the set standard parameter, so as to give out accelerating or decelerating instructions.
