摘　　要：在复杂的交变载荷作用下,吊卡构件的薄弱部位极易疲劳、萌生裂纹,进而导致断裂失效。通过对国内目前常用的CDZ133- 315 0kN侧开式锥形台阶钻杆吊卡三维应力进行分析,绘出应力分布图和塑性应变图,并分析吊卡的结构强度,计算在规定安全系数下吊卡的许用载荷和额定应变下吊卡的安全系数.CDZ133 - 3150kN side - door type conical bench drill pipe elevator is a kind of loadcarrying tool which can put conical bench drill pipe in and out of the hole. In a complicated alternate load, some parts of elevator structural component are easy to fatigue and split, leading to breaking of elevator. The paper analysed the 3D stress of CDZ133 -3150kN side-door type conical bench drill pipe used in China, and drew the stress distribution graph and plastic strain plan. At the same time, the paper also analysed the structural strength of the elevator, and calculated the permissible load and safety coefficient of elevator.
