Specific embodiment
As shown in Fig. 1~2, a kind of coal mining elevator, the reel 2 including main support 4, on main support 4 and
One brake 3, the first brake 3 are disk brake, and 4 one side of main support is fixed with electric machine support 5, is installed on electric machine support 5
Motor 6, the output terminal of motor 6 are connected with retarder 9, and the output terminal of retarder 9 is connected with 2 one end center of reel, reel 2
The other end be connected by main shaft 21 with bearing, bearing is fixed with bracing strut 28, and bracing strut 28 is fixed on main support 4, reel
Upper 2 are wound with steel wire rope 1, and steel wire rope 1 bypasses the head sheave 8 being mounted on derrick 7 and is connected with suspension hook, also pacified on the main support 4
Equipped with second brake, second brake includes turntable 10 and bar 11, and turntable 10 is fixed on reel 2,10 excircle of turntable
On be uniformly fixed with convex block 12, bar 11 is hinged by fixed pin and main support 4, and micromachine 13 is fixed on main support 4, micro-
