综掘机液压张紧装置的改进设计
|
摘要
丁集煤矿目前使用的掘进机较多,在使用过程中由于张紧拉力和运行作用会使行走部履带和第一输送机刮板链张紧程度变松,需要不定期的对履带和刮板链进行张紧。原有张紧操作步骤繁琐,影响作业时间,通过对掘进机液压张紧装置进行改进,使张紧过程变得方便,且从根本上减少了事故率,极大地减少了作业时间及工人的检修强度。
There are many roadheaders in Dingji Coal Mine at present, in the course of using, the tension of the track and scraper chain of the first conveyor become loose due to the tension force and operation, it is necessary to tension the track and scraper chain from time to time. The original tension has complicated steps and effects of operation time, based on the roadheader slewing hydraulic tensioning device has been improved, so the tensioning process can become convenient, and it can fundamentally reduce the accident rate, greatly reduce the maintenance work time and repairing intensity of workers.
