绳索取心绞车是绳索取心钻进的重要辅助设备之一，它与提高钻进效率及时间利用率，与安全及排绳状态等有极大关系，因此，对其结构及工作性能的研究不容忽视。为适应我队绳索取心钻进的需要，进一步提高绳索取心钻进效率，改善配套状况，并根据我队施工条件，笔者在去年年中设计了由电机单动驱动的行星轮系传动绞车，即Js-j型绞车。在北京探矿厂及王义兴同志的大力协助下，很快完成了加工任务，于去年八月开始试验，截至目前已运转提升约4000米，证明性能良好（此绞车已由北京探矿厂批量生产）。
Rope winch is one of the important auxiliary equipment for rope coring drilling. It has great relationship with improving drilling efficiency and time utilization, safety and rope condition. Therefore, research on its structure and working performance Can not be ignored. In order to meet the needs of our team’s cord drilling, to further improve the efficiency of rope coring drilling to improve the matching conditions, and according to our team construction conditions, the author designed in the middle of last year by the motor single-drive planetary gear drive winch , That is, Js-j type winch. With the great assistance of the Beijing Prospecting Factory and Comrade Wang Yixing, the processing task was quickly completed and the test was started in August last year. As of now, the operation has been improved by about 4,000 meters to prove good performance (this winch has been mass-produced by Beijing Prospecting Factory).
