新副井筒绞车提钢丝绳安全系数校验.doc

副井筒绞车提升能力计算 一、概述 新副井全长648米，倾角25度，铺设钢轨30kg/m，轨距为600mm，安装绞车型号为：JK-3/20E，钢丝绳最大静张力：130KN，配用钢丝绳为6X7-φ32，钢丝绳破断拉力总和为72.15T，该绞车承担着采区支架入井及三采区矸石提升，提升最大物料为ZFG5300/18/29型放顶煤过渡过支架，重17.6t，提矸石时提5个矿车，矸石重量为1700kg，矿车重800kg，共重12.5T。按各提升件重量分别将绞车提升能力计算如下： 一、支架提升计算 1、提升支架时绞车的提升能力： 钢丝绳作用在绞车滚筒上的最大静张力为: Fjm=(Qz+Q )(sinа+f1cosа)+PcL (sinа+f2cosа) =（17.6+1.5）90KN，配用钢丝绳为6X7-φ31，钢丝绳破断拉力总和为47.25T，提升最大物料为ZFG5300/18/29型放顶煤过渡过支架，重17.6。提矸石时提6个矿车，矸石重量为1700kg，矿车重800kg，共重15吨，按最大重量计算。 1、绞车提升能力计算 钢丝绳作用在绞车滚筒上的最大静张力为: Fjm=(Qz+Q )(sinа+f1cosа)+PcL (sinа+f2cosа) =（17.6+1.5） 编 制：史忠义 审 核：李 岩 机电科长：尚军科 安检科长：杨正刚 机电经理：左志强 安全经理：段金红 总工程师：李文科 二0一0年九月二日 I signed with the Bank of the qilu Bank loan contract (contract) conventions, and I use scheme, I would request the loans (in words) until I opened personal settlement account with your Bank (account), uses loan for 。 Loan operation, business unit name: account number: loan funds from these personal settlement account into the account of a payment.
