一、概述国内外矿用液压绞车发展较快。六十年代末期已逐渐用于煤矿井下提升和作其他牵引。我国1976年开始研制矿用液压绞车。现已形成系列产品的是湖南省煤矿专用机械厂生产的BYT—1.2和BYT—1.6型。(外形见本刊1985年第2期封面——编者)。淮南煤机厂生产的JT—1200Y型也已鉴定合格。液压绞车具有下述优点: 主传动采用液压传动,简化了电气控制系统,易于达到防爆要求,能在瓦斯矿井井下使用。液压绞车工作制动靠容积调速闭式回路实现。不象电绞车那样需要闸瓦给予的外部
I. Overview At home and abroad mining hydraulic winch developed rapidly. The late sixties have gradually been used for underground coal mine and other traction. Our country began to develop mining hydraulic winch in 1976. Now formed a series of products is the Hunan Coal Mine Machinery Factory BYT-1.2 and BYT-1.6 type. (See the appearance of the second issue of 1985 cover - editor). Huainan coal plant production JT-1200Y type has also been identified qualified. Hydraulic winch has the following advantages: The main drive using hydraulic transmission, simplifying the electrical control system, easy to achieve explosion-proof requirements, can be used underground gas mine. Hydraulic winch brake work by volume closed-loop speed control to achieve. Unlike the electric winch that needs to be given outside the brake shoe
