Example 1

Referring to fig. 1, the double-speed drive of the overhead man-riding device for coal mine comprises an explosion-proof motor 1, a frame 2, a coupler 3, a working brake 4, a transition shaft device 6, a driving wheel 7, a safety brake 8 and a broken shaft protection 9, wherein the top of the frame 2 is connected with the explosion-proof motor 1 through a fastening bolt, an output shaft of the explosion-proof motor 1 is connected with the coupler 3 through a fastening bolt, one side of the coupler 3 is connected with the working brake 4 through a fastening bolt, the bottom of the frame 2 is connected with the safety brake 8 through a fastening bolt, the bottom of the safety brake 8 is connected with the broken shaft protection 9 through a fastening bolt, one end of the coupler 3 far away from the explosion-proof motor 1 is connected with a double-speed reducer 10 through a fastening bolt, the bottom of one end of the double-speed reducer 10 is connected with the transition shaft, when transport personnel at ordinary times, the dual speed reducer 10 speed reduction ratio is adjusted in less position, adjusts the dual speed reducer 10 speed reduction ratio in great position when needs are when overhauing, only needs to change dual speed reducer 10 and just can realize two kinds of speeds, need not change other electrical structure, and the principle is simple, and is with low costs.

Wherein, the top of double speed reducer 10 is connected with speed reducer adjustment handle 11 through fastening bolt, when needing less speed, adjusts speed reducer adjustment handle 11 to great reduction ratio, when needing great speed, adjusts speed reducer adjustment handle 11 to less reduction ratio.

Wherein:

the running speed of the steel wire rope: v = K × π D/60 × Ne/i

K-creep coefficient of steel cable when running, taking K as 0.98

D-Driving wheel diameter is 1400

Ne-motor speed

i-speed reducer reduction ratio

According to a calculation formula, under the condition that the rotating speed of the motor and the diameter of the driving wheel are not changed, the speed reduction ratio of the speed reducer is adjusted, and speed change can be achieved.

The two-speed reducer 10 is provided with a reducer adjusting handle 11 which can adjust two positions of the reduction ratios 63 and 90.

When the overhead man-riding device normally transports the man, the reduction ratio is adjusted to 63,
