无极绳绞车选型(国外英文资料)
无极绳绞车选型(国外英文资料)
The type design of the backwind, unpole rope winch
First, basic conditions
10, return air gateway transportation distance is 1000 m, more ups and downs, maximum gradient 10 °. The rail type 22kg/m, the gauge is 600mm, the platform car pulls the height 180mm, the plate axle is 50mm from the end of the rail, the maximum transport bracket weight 15t (including the flat car).
Choice calculation
1, the traction calculation:
Type: - transport maximum weight of 15t; -- the shuttle weighs 2t.
- running line maximum slope 10 °; -- the coefficient of drag resistance of steel wire rope;
Unit length wire rope (optional 22NAT6 x 19S + FC1670SZ317207GB/T8918) weighs 1.74 kg/m; Transport distance 1000m; The acceleration of gravity.
The traction is:
F = (13 + 2) * 1000 * 9.8 * (0.05 COS10 ° + Sin10 °) + 2 * 0.5 * 1.74 * 1.74 * 1000 = 49833 n material 49.833 KN 60 KN
Selection of the winch
Based on the above traction calculation, the winch with the maximum traction of 60KN is suitable, and the speed is the mechanical speed. Therefore, the JWB55B type infinity rope winch is perfectly satisfactory.
Power checking:
N = FV / = 49833 * 0.67 (0.8 times 1000) is approximately 41.74 KW
In type: V - traction time; -- winch drive efficiency 0.8;
The wire rope is used for 22NAT6 * 19S + FC1670SZ317207GB/T8918
The safety factor of the wire rope is n:
Conforming to the regulations of the coal and safety regulations
22 mm - 6 x 19, wire rope ¢breaking force sum (manual);
The maximum traction of the wire rope is 49.833 KN
Sc - wire rope tension primary value: 10KN
Plan selection design
Design selection principle:
(1), adopts mechanical speed regulation method, equipped with explosion-proof motor and flameproof electric hydraulic brake, can be applicable to the coal mine gas and coal dust homework, equipped with reducer;
(2) the way of continuous tractor arrangement of endless rope: the main auxiliary wire rope is placed in the orbit.
(3), in addition to the roadway bumps in layin
