在岩心钻探中使用的钻机，卡盘是常用的部件，它把钻机的扭矩和轴向力传递给钻具，以进行钻进工作。随着钻探技术的发展，有些立轴式钻机或动力头式钻机，对卡盘的应用范围由原来仅完成钻进工作中的传递轴心压力和扭矩作用发展到要完成钻具的提升工作。特别金刚石钻进的广泛采用，对卡盘提出了新的要求，因而钻机卡盘结构得以不断改进，目前已从原有的手动卡盘向着液压多用和连续作用方面发展。本文通过对现有国内外 Drilling rigs used in core drilling, chucks, are common components that transmit the torque and axial force of the rig to the drill rig for drilling operations. With the development of drilling technology, some vertical shaft drilling rigs or powerhead drilling rigs have been applied to chuck applications ranging from the transmission of axial pressure and torque in drilling operations to the completion of rig upgrading. The widespread adoption of special diamond drilling has raised new demands on the chuck. As a result, the chuck structure of the drilling chuck has been continuously improved. At present, it has been developed from the original manual chuck to the hydraulic multi-purpose and continuous effect. This article through the existing at home and abroad
