全自动液压吊卡的研制

Development of the Automatic Hydraulic Elevator

针对钻修井作业过程中传统的机械式吊卡的效率低、风险高的问题,研制了全自动液压吊卡。该吊卡采用液压驱动,可以实现司钻远程控制及信号反馈,吊卡主体可进行±90°的翻转,内部设有自锁机构。根据API 8C对设备进行强度校核,并通过有限元分析对主要受力部件进行分析,结果表明该液压吊卡满足设计要求。为了充分验证液压吊卡的可靠性,对设计成果进行了样机试制并进行了功能试验和载荷试验。各项数据表明,该液压吊卡满足现场使用要求。

To solve low efficiency and high safety risk problem of the traditional mechanical elevator in the process of drilling and workover operation,this paper studies a full-automatic hydraulic elevator,which can realize the remote control of driller and signal feedback.The elevator body can rotate±90°,and a self-locking mechanism is set in the elevator.Finally,we execute strength check of the equipment according to API Spec 8C,and analyze the main stressed components on the basic of finite element analysis.The results show that the hydraulic elevator satisfies the design requirements.In order to demonstrate the effectiveness and reliability of the hydraulic elevator,we carry out prototype trial production,functional tests,and load tests of the design results.The data show that the hydraulic elevator satisfies the operating requirements of field.
