矿用提升机直推平移式弹簧闸的研究

提出了矿用提升机直推平移式弹簧闸．对其结构进行了分析，并对技术参数进行了计算与测定．这种制动装置具有以下特点：（１）结构简化．传动环节减少．提高了安全可靠性；（２）空动时间缩短．灵敏度提高，传动效率大大提高；（３）同角移式为构比较，消除了闸块由于先后接触而产生的附加应力．产生的惯性也较小；（４）采用油缸和弹簧联控，实现用环运行，易于操作．６个月的工业运行试验显示了这些特点．

Study on tab Driect-push Spring Brake with Parallel Shift of Mine Winders

The construction of the direct-push spring brake with paranel shift of mine winders have been analysed and its technological parameters have been calculated and tested. The brake has some advantages as following: (1) simpler construction,fewer transmission installarion and better reliability;(2) less anavailable operation time,higher sensitivity and greater efficiency intransmission; (3) Compared the direct-push brake with the angle-shift one,this brake can avoid the extra stress which caused by the connection of the brakes,thus,the inertia force becomes smaller; (4) A combination controlling with oil cylinder and spring brake in the properties Performances of the sir months have proved that a closed circulating and an easier operation can be provided by this brake System.
