风动回柱绞车自60年代问世以来,已在法国、西德等国采矿业中得到广泛的应用。这一新型回柱设备能否在我国的急倾斜煤层和高沼气矿井推广使用,正引起人们的关注。南京煤矿机械厂的JFY——10型风动回柱绞车(以下简称:风绞)产品从试制、鉴定到批量生产已近6年了。通过井下(尤其是高沼气矿井、急倾斜煤层)的实际使用,证明这是一种高效率的回柱设备。一、工作原理和主要技术特征 JFY——10型风绞由主机、起重圆环链、进口管路及附属装置等部分组成(如图所示)。
Since the advent of the 1960s, the wind-driven column winch has been widely used in the mining industry in France, West Germany and other countries. Whether this new type of post-column equipment can be used widely in the steep seam and high-methane mines in our country is arousing people’s attention. Nanjing Coal Mine Machinery Factory JFY - 10 type pneumatic rotary column winch (hereinafter referred to as: wind twist) products from trial production, identification to mass production for nearly 6 years. The practical use of downhole, especially high methane mines, steep coal seams, proves to be an efficient backfill device. First, the working principle and the main technical features JFY - 10 type wind from the host by the host, the lifting ring chain, imports of pipelines and ancillary equipment and other components (as shown).
