摘　　要：煤矿耙斗装岩机原有的辅助制动闸使用刚性制动,用来防止由于速度突变使钢丝绳堆积、乱绳,但刚性制动容易造成钢丝绳受到反复冲击振动,造成钢丝绳寿命缩短。研发了一种自适应柔性辅助制动闸速度调节系统,采用二次制动的防抱死技术,第1次制动是制动轮自适应减速缓存,第2次是抱死的,可以最大程度降低速度的突变,并且保护了钢丝绳免受冲击和振动。柔性辅助制动闸能够更好地适用于各种煤矿耙装机、各种需要高难度的工作强度,能够取得良好的使用效果,对钢丝绳和耙矸机具有很好的保护作用。The original auxiliary brake of coal mining scraper mucker is using brake rigidity,used to prevent due to velocity mutation to make wire rope rope,but rigid brake wire rope under repeated impact vibration easily,cause the wire rope life expectancy.Developed an adaptive flexible auxiliary brake speed regulating system,adopting secondary braking antilock technology,for the first time the brake is brake wheel adaptive cache a slowdown,the second is lock,can maximum reduce the rate of mutation,and to protect the steel wire rope from shock and vibration.Flexible auxiliary brake can better apply to all kinds of coal rake installed,all kinds of needs hard working strength,can obtain the good use effect,the wire rope and rake bottles machine has the very good protection effect.
