摘要
介绍了一种煤矿用单作用自动液压增压器。通过利用综掘机的液压系统,在保证支护设计要求的前提下,实现了对顶板的全锚索支护。重点阐述了增压器的工作原理、设计思路、结构特点及主要参数。工业性试验表明,该增压器在理论上、技术上是可行的,并且使用方便,经济效益显著。
A kind of hydraulic automatism - booster in coal mine was studied. Through using of driving machine hydraulic system and in the design requirements. It could realize the cable - wide support in coal mine. The structure and the operating principle of the automatism - booster are introduced in detail. The parameters and design thinking were also obtained. Through industrial test in coal mines, it shows that the research on automatism - booster was viable in theory and technology and it is convenient to use, high productivity and with obvious economic benefit.
