立井提升装置过卷动力学研究
|
摘要
针对立井提升装置的过卷制动特性,从动力学入手,建立了提升装置过卷时的动力学模型,提出了过卷制动力、制动减速度和钢丝绳冲击力的计算方法,计算结果表明:罐笼提升过卷制动减速度应小于重力加速度g,箕斗提升过卷制动减速度应小于2g。同时提出了限制钢丝绳冲击力的设计方法,基于限制冲击的理念,优化了HGJ-D钢带式立井提升过卷缓冲装置的制动性能。结果表明:采用限制冲击力的过卷防护装置,可以减小井架、井塔的受力,最多可使提升钢丝绳承受的冲击力减少1/2,从本质上提高了提升系统的安全可靠性。
According to overwinding braking features of a mine shaft hoisting device,from view of a dynamics,overwinding dynamics model of the hoisting device was established. A calculation method of overwinding braking force,braking deceleration and steel wire rope impact force was provided. The calculation results showed that overwinding braking deceleration of cage hoisting should be less than g and overwinding braking deceleration of skip hoisting should be less than 2g. A design method to restrict the impact force of the steel wire rope was provided. Based on conception to restrict the impact,the braking performances of HGJ- D steel band type overwinding buffer device were optimized for the mine shaft hoisting. The results showed that the overwinding protection device to restrict the impact force applied could reduce the stresses of mine shaft headframe and mine shaft tower,could reduce 1 /2 impact force to the hoisting steel wire rope and could improve the safety reliability of the hoisting system
