摘　　要：针对目前常规钻井绞车传动链长、机构庞大、控制系统复杂、生产成本高、制造难度大等问题,开发一种多档位液压马达直驱钻井绞车。该绞车由2个对称布置的液压马达直接驱动滚筒轴,采用电液控制技术,通过液压马达不同排量组合实现绞车的多档位控制。液压动力单元通过比例控制方式,实现绞车在各档位的无级变速。该绞车具有动力传动和控制系统简单、功率密度大、体积小、重量轻等特点,可广泛应用于小型陆地钻机和修井机。Aiming at the current problems of conventional drawworks,such as long transmission chain,huge mechanism,complex control system,high production cost and difficult manufacturing,a multi-gear hydraulic motor direct drive drawworks was developed.The winch is directly driven by two symmetrical hydraulic motors,which adopt electro-hydraulic control technology and realize multi-gear control of the winch through the combination of hydraulic motors with different displacement.The hydraulic power system realizes the continuously viable speed regulation of the drawworks in each gear position through proportional control.The drawworks has the characteristics of simple power transmission and control system,high power density,small size and light weight,which can be widely used in small land drilling rigs and work over rigs.
