煤矿综采工作面的煤炭采掘、运输主要是靠“三机”(采煤机、液压支架、刮板输送机)来完成的,其中刮板输送机与液压支架的配套使用是由刮板输送机的中部槽推移耳与液压支架的推移千斤顶用销轴连接的,销轴的固定通常采用开口销加挡圈的形式,这种固定方式存在强度及可靠性低等缺陷。针对这种问题,该公司开发了一种新型快换式中部槽推移耳与液压支架连接结构,有效地解决了以上问题,既增加了销轴的固定强度,又能快速拆装销轴。
Coal mining in fully mechanized mining face, transportation is mainly by “three machines ” (shearer, hydraulic support, scraper conveyor) to complete, in which scraper conveyor and supporting the use of hydraulic support from scraping Push the middle of the plate conveyor groove and the hydraulic jack bracket push the pin with a pin, the pin is usually fixed with open pins plus retaining ring in the form of this fixed existence of low strength and reliability defects. In response to this problem, the company has developed a new type of quick-change middle groove push ear and hydraulic support connection structure, which effectively solves the above problems. It not only increases the fixing strength of the pin shaft, but also can quickly dismount the pin shaft.
