| 摘 要： | 传统机械立轴式钻机主卷扬具备自由落钩性能、下放钻具快的优点，但存在带式石棉刹车不耐磨、摩擦系数低、操作费力、灵敏度不高、散热性能不好、高温使用性能不好、下降到孔口安全距离不好控制等缺点。全液压动力头钻机用主卷扬采用液压系统流量控制提升与下降速度，孔口安全距离较好控制，通过液压系统强制散热，散热性能良好，但不具备自由落钩功能。为此研发了一种全液压岩心钻机用液压盘钳式刹车卷扬机，其能够在以上2种工作方式中自由切换，并且解决了带式石棉刹车不耐磨、摩擦系数低、操作费力、灵敏度不高、散热性能不好、高温使用性能不好等问题。

| Abstract: | The master winch of traditional spindle mechanical drilling machine has both the advantages of hook free-falling and rapid drilling tools lowering and the disadvantages of low abrasion resisting of belt asbestos braking, low friction coefficients, difficult operation, low sensitivity, poor heat dissipation, poor high temperature property and difficult safety control for drilling tools assembling and disassembling. For the master winch of full-hydraulic dynamic head drill, the elevating speed is controlled by the flow of hydraulic system, the safety of drilling tools assembling and disassembling is easily guaranteed, and the cooling forced by hydraulic system is also good. A hydraulic winch of full-hydraulic core drill is developed; the above problems of the master winch of traditional spindle mechanical drilling machine are solved by hydraulic pressure. |
