摘 要: | 为解决在深立井中,由于提升绳弹性伸长较大,提升重物时罐笼反弹较大,经常造成罐笼掉道事故的问题,首先建立容器在井底的力学模型,借助Matlab的数学功能对提升绳弹性力进行分析;通过对井底稳罐技术进行分析,提出采用限力补偿方式可以消除或控制住反弹力,利用容器定位锁定的方法,可实现容器的定位问题。并研制出相应的装备,经试验验证可以达到设计要求。

Stabilizing cage technology of deep shaft friction hoist |

Abstract: | Cage off accident is frenqutly caused by the bounce of cage due to the big elastic stretching of lifting rope,when cage lifts load in deep shaft.To solve this problem,dynamic model of cage at the bottom of deep shaft was established,and the analysis of elastic force of rope was done by virtue of mathematical function of Matlab.After the technological analysis of stabilizing cage,proposed compensatory type to remove or control the rebound force,and use the method of locking cage orientation to realize the orientation of cage.Besides,the development of corresponding equipment is tested to meet the requirement of design. |
