为适应煤炭工业发展需要,重庆矿山机器厂最近研制出一种适用于在煤尘严重和瓦斯突出危险情况下工作的JHF—10型风动回柱绞车。该产品采用压缩空气驱动,由叶片式发动机发动,通过两级行星齿轮减速和一级链轮减速,带动主链轮,由主链轮带动环形链输出动力。其特点是:1、绞车动力不用电源,不会产生电弧火花而引起瓦斯爆炸的可能性,对瓦斯严重的矿井具有较大的安全可靠性。耗能量较小,对节约能源有一定的经济意义。2、产品结构紧凑,体积小,机器外型尺寸为580×304×345毫米。3、重量轻,强度高,坚固耐用。绞车的杨体和部分零件,选用高强度铝合金材料,主机重80公斤,同8吨电动回柱绞车相比较,体积仅为它的1/5,重量为它的1/8。容易搬动。4、拉力为8吨回柱纹车的1.25倍。5、操作简单,维修方便。样机经矿井现场工业性运厅试用,性能良好,技术参数达到设计要求,受到用户的欢迎。该绞车鉴定会于1682年6月在重庆旷山机器厂召开,会议试人该产品结构紧凑、轻匣、安全性能好,各项性能指标符合设计要求。产品图纸、技术文件基本齐全、正确,符合国家标准和有关专业标准,工艺文件和工艺装备基本具备,同意进行批量生产。
In order to meet the needs of the development of the coal industry, Chongqing Mining Machinery Factory recently developed a suitable JHF-10 type pneumatic rotary column winch which is suitable for working under the condition of serious coal dust and gas outburst. The product is driven by compressed air and is driven by a vane-type engine. The two-stage planetary gear reduces speed and the first-class sprocket decelerates to drive the main sprocket and the main chain wheel drives the endless chain to output power. Its features are: 1, winch power without power, will not produce arc sparks and the possibility of gas explosion, mine gas has a greater safety and reliability. Small energy consumption, to save energy has some economic significance. 2, the product structure is compact, small size, machine dimensions of 580 × 304 × 345 mm. 3, light weight, high strength, durable. The winch Yang body and part of the parts, the choice of high-strength aluminum alloy, the host weighs 80 kg, compared with the 8-ton electric column winch, the volume is only 1/5 of its weight is 1/8. Easy to move. 4, Rally for 1.25 tons of 8-ton column pattern car. 5, simple operation, easy maintenance. Mock-up by the mine on-site industrial transport hall trial, good performance, technical parameters to meet the design requirements, welcomed by users. The winch identification will be held in June 1682 at the Wun Mountain Machinery Factory in Chongqing. The conference attendee has compact structure, light box and good safety performance. The performance indexes meet the design requirements. Product drawings, technical documents basically complete, correct, in line with national standards and relevant professional standards, process documentation and basic equipment available, agreed to mass production.
