煤矿井下绞车安装措施(国外英文资料) Safety technical measures are installed on 7118 lane winch The formulation of the description: 7118 district construction machine lane for 24 ° up the hill, he found winch to ascend, to ensure that the inclined lane transportation safety, formulation of this measure. Equipment selection: The route is more than 75 meters high and is proposed to use a jd-25 winch. Wire rope choose 6 x 19 - Φ 15.5-155 wire rope. A tonne of mine hauling material, the winch hoisting one car at a time. The base of the jd-25 winch, which is based on the base of the winch base, and the base of the long * wide * depth = 1200 * 1200 * 1200, and the concrete is watered by concrete. The winch foundation is made of M22 anchor rod, and the length of the anchor rod is not less than 100mm. Third, improve the ability to verify Roadway slope as 24 °, the length of 75 m, wire rope weight ㎏ 0.85 per meter. Maximum traction for 20 kn, choose a diameter of 15.5 mm, weight of wire rope ㎏ 0.85 per meter. Jd-25 winch check: Compute the jd-25 winch terminal load: So its going to be the same thing as the sine of beta plus the sine of beta plus w1 cosine of beta. The meaning of the symbol is: Z: increase the number of mines, z = 1 G: the weight of the mine car, G = 1800kg (calculated by the maximum charge) G0: the mine car weighs itself, G0 = 600kg Ps: wire rope weight, Ps = 0.85 kg/m Beta: roadway slope, beta = 24 ° W1: the mining vehicle runs resistance coefficient, W1 = 0.01 W2: the wire rope increases drag coefficient, and W2 = 0.3 L1: increase the terminal distance, take L = 100m Fj = [1 x (1800 + 600) (sin24 ° cos24 + 0.01 °) + 0.85 x 100 x (sin24 ° cos24 + 0.3 °) x 9.8 = 9.9 KN 20 KN The jd-25 winch is required Qd Z (G0 + G) (sin beta + w1 cos beta) + PsL1 (sin beta + W2cos beta) Wire rope strength checking: M = Qd/Fj: = 158/9.9 = 15.9 6.5 M 6.5 fits the rules. Safety and technical measures (1) the system of strictly enforcing pedestrians not driving, driving no people. (2) the wi
