LS70DB电动捞砂绞车的研制与应用

交流变频电驱动单轴齿轮传动绞车由于没有配备专用的捞砂滚筒,无法完成捞砂、部分测试和试油工作,为此,研制了一种单橇交流变频电驱动捞砂绞车。该绞车采用交流变频控制,实现无级调速;主刹车采用电动机能耗制动,辅助刹车采用带棘爪机构的带式刹车;机械传动采用摆线减速器与链传动相结合的传动方式;捞砂计量装置采用单片机微控器作为中央处理单元的数字控制模式。现场的反馈信息说明,该绞车完全满足使用要求,具有极高的机动性和灵活性,1台绞车可以为多台钻机提供服务,使用效果良好。

Development and application of the LS70DB electric bailing winch

The electric uniaxial gearing winch cannot satisfy the requirement of bailing conditions.To satisfy the practical requirement of bailing operation of the drilling equipment,a kind of single-crowbar alternating current variable frequency electric bailing winch was developed.The winch is controlled by alternating current variable frequency and it achieves stepless speed regulation.The main brake adopts energy-consumed braking;the auxiliary brake adopts the new-type band brake;the mechanical drive adopts a driving method which combines cycloidal reducer and chain drive;the bailing metering unit adopts the digital control mode which uses the single-chip microcontroller as the central processing unit.The field feedback information shows that the winch can completely satisfy the requirement for application with a high mobility.One winch of such kind can provide service for quite a few drilling rigs simultaneously.The application effect is desirable.
