发布时间：2018-11-17 08:27
【摘要】：游车是石油钻机的提升设备之一,在钻井和修井作业中,主要用于悬吊钻柱和处理钻井事故,国内外有多家生产厂商。常见游车结构由上横梁滑轮滑轮轴左侧板组右侧板组下提环提环销等组成。本文完成YC450游车的结构改进,改变了原游车侧板组结构件,取消了原设计中销座和销轴,将销座功能集成到侧板组中,有效解决了销座变形等问题,改变了滑轮轴轴肩长度,降低原游车总成的4.6%,降低生产成本,提升了侧板安全系数0.22,提升了整个系统的可靠性。按照API Spec 8C 2012版规范,主要对关键零部件进行计算,利用UG NX5.0设计软件建立各个零部件的三维模型,然后将各个模型导入到有限元环境,按照零部件的设计载荷和使用要求等工况,考虑各种载荷组合情况,对各个零部件进行了有限元计,依据有限元计算结果和理论分析结果,按照API Spec 8C 2012版中的相应条款和设计材料指标给出了各零部件的安全系数。目前,结构改进后的YC450游车已投入实际生产,较比之前制造和维修成本降低,每年提升利润20万元以上。
[Abstract]:Yam is one of the lifting equipment of oil drilling rig. In drilling and workover operation, it is mainly used for suspending drill string and dealing with drilling accident. There are many manufacturers at home and abroad. Common tour car structure from the upper beam? Pulley? Pulley shaft? Left panel? Right board? Lower ring? Lift ring pin, etc. In this paper, the structure improvement of YC450 bobbin has been completed, which has changed the structure of the side plate group of the original trolley, eliminated the pin seat and pin shaft in the original design, integrated the pin seat function into the side plate group, effectively solved the deformation of the pin seat, and changed the length of the axle shoulder of the pulley shaft. The safety factor of the side plate is 0.22 and the reliability of the whole system is improved. According to the specification of API Spec 8C 2012, the key parts are calculated, and the 3D models of each component are built by using the UG NX5.0 design software, and then the models are imported into the finite element environment. According to the design load and operation requirements of the parts, considering the various load combinations, the finite element method is used to calculate the components, according to the results of the finite element calculation and the theoretical analysis. According to the corresponding terms of API Spec 8C 2012 edition and design material index, the safety factor of each part is given. At present, the improved YC450 has been put into actual production, lower than the cost of manufacturing and maintenance before, and the annual profit is increased by more than 200000 yuan.
