Abstract

一种新型的高效节能、节材无级调速岩心钻机， 不仅实现了岩心钻机的无级调速，满足了多种钻进工 艺的需要，提高了工效，降低了电机的无功损耗，加 之，省去了现有钻机变速机构部分的大部分变速齿 轮，所以这种新型岩心钻机结构简单，操作方便，成本 低廉，易于制造。

Description

本实用新型涉及煤田地质勘探领域中应用的岩心钻机。
目前公知的岩心钻机，都是由机械变速，液压进给的有级变速。其变速机构复杂，加工困难，成本高，电机的耗电量及无功损耗很大。不同地层，不同钻进方法和铅头直径需要不同的调速范围以适应围以适应最优钻进规程的需要，尤其钻机回转机构为恒功率输出时，其转速与转矩成反比，即当回转器的转速为最高时其输出转矩最小，因此，传统的有级变速岩心钻机很难同时满足多种钻进工艺的需求。
本实用新型的目的是提供一种可以无级调速岩心钻机，它能针对不同钻进条件采用不同的钻进速度，同时能减化钻进结构提高效率。
本实用新型的目的是这样实现的：利用交流无级调速电机通过联轴器和减速箱联接，通过锥齿轮带动回转器。利用交流无级调速电机的调速特性来改变回转器的转速。
同现有岩心钻机相比，本实用新型可省去变速箱离合器，减化其分动箱，降低成本，提高效率。
实用新型的具体结构由下述实施例及附图给出。
图1是交流无级调速岩心钻机的主传动系统图。
下面结合图1具体给出实施例。
交流无级调速电机（1）直接与减速箱（2）的输入轴相连，减速箱输入轴通过齿轮副（3）驱动分动箱（4）。分动箱输出轴通过锥齿轮副（6）驱动回转器（5）。

Claims (2)

1、一种交流无级调速岩心钻机，其特征在于交流无级调速电机(1)通过联轴器带动减速器(2)的齿轮副(3)，减速器输出轴通过分动器(4)与锥齿轮副(6)相连，通过控制电机(1)的转速实现调节回转器的转速。
2、如权利要求1所述钻机，其减速机（2）可以是多级齿轮副或蜗轮蜗杆减速机。
