介绍一种新型的卷扬式卧式活套,其主要由活套车、支撑车、力矩卷筒及传动卷扬构成,具有结构简单,安装方便,使用可靠且设备投资少的特点。另外基于力矩卷筒的力学特性,建立了活套的运动模型,对其运动过程进行了详细分析,并提出了力矩卷筒钢丝绳强度校核时需注意的事项。 This paper introduces a new type of winch horizontal looper, which is mainly composed of a looper, a supporting car, a torque drum and a transmission winch. The utility model has the characteristics of simple structure, convenient installation, reliable use and less equipment investment. In addition, the motion model of the looper is established based on the mechanical characteristics of the torque drum. The movement process of the looper is analyzed in detail, and some precautions to be taken when checking the strength of the torque drum wire rope are put forward.
