摘　　要：针对深井井筒施工过程中的提升吊桶横向摆动问题,通过吊桶稳绳横向刚度模型分析,弄清了提升吊桶横向摆动的主要影响因素,进行了基于高精度激光测距传感器和加速度传感器的提升吊桶横向摆动量测系统设计、实施和现场实测。结果表明：吊桶提升运行过程中,可以实现摆动位移及竖向振动的实时监测;在测试条件下,吊桶在升降过程中,一直处于频率0.4~0.6Hz的竖向振动状态,横向摆动最大摆幅约100mm。Since lateral oscillation of hoisting bucket has seriously impact on deep shaft sinking,the lateral stiffness model of hoisting bucket guide ropes was established and the main influence factors on the lateral oscillation of hoisting bucket were analyzed in this paper.By using high-precision laser sensors and acceleration transducers,a real time measuring system on the lateral oscillation of hoisting bucket was designed,and series field tests were carried out in Sishanling Iron Mine.The results show that the designed measuring system is available and the test data has good accuracy;Under the field test condition,hoisting bucket is in a state of vertical vibration at frequency of 0.4 ~ 0.6Hz,the maximum extent of lateral oscillation is about 100 mm.
