摘要
为满足钻井工艺和运输要求,通常把绞车设计成多轴传动、分体运输,这样不仅使系统复杂,还增加了成本和安装工作量。为此,对绞车的传动方案、动力输入方式和绞车架结构做了开创性工作,重新设计了ZJ70D型双滚筒绞车。该绞车主要由底座、绞车架、滚筒轴、捞砂滚筒轴、传动轴驱动箱、盘式刹车、防碰天车装置、主刹车机构和自动送钻装置等组成,动力输入轴与传动轴之间换挡采用机械换挡,传动轴与滚筒之间的换挡采用气胎离合器换挡,拥有4个正挡、4个倒挡。运用有限元软件对滚筒轴进行了模拟分析和强度、刚度校核。分析与校核结果表明,绞车滚筒和机架设计合理,满足实际工作要求。
To satisfy requirements related to drilling and transportation,winches are usually designed with multiple shafts to facilitate transportation of individual components. Such design not only makes the system more complicated,but also increases relevant costs and workloads for installation. In this regard,transmission systems,power inputs and structures of the winch have been re-designed to produce the ZJ70 D dual-drum winch. Major components of the winch include the mounting base,winch rack,drum shaft,bailing drum shaft,driving gear box for transmission shaft,disc brake,crown block saver,master braking system and automatic bit delivering system. Mechanical gear-shifting system is used between the power input shaft and the transmission shaft,whereas pneumatic gear-shifting system is used between the transmission shaft and the drum. The system has 4 forward gears and 4 backward gears. Finite-element software is used for simulation,analyses and calibration of strength and rigidity of the drum shaft. The results show that the drum shaft has required strength and rigidity. Generally,the winch drums and the racks have proper design and can satisfy relevant requirements for field application.
