The invention relates to the technical field of film and television props, and discloses a wire running trolley for avoiding breaking of a steel wire rope. The wire running trolley comprises two moving frames, wherein the upper ends of the moving frames are provided with traveling wheels, the two moving frames are fixedly connected through breaking bolts, and the upper ends of two sides of the moving frames are movably connected with sliding blocks. According to the wire running trolley for avoiding the breaking of the steel wire rope, when motors on the two sides run asynchronously, the breaking bolts bear action firstly and absorb excessive pulling force, so that the steel wire rope is prevented from being broken, reaction time is provided for an operator, at the same time, the travelingwheels stop rotating, the traveling wheels and a traveling track emit huge noise, and if the motors are not stopped in time, the two moving frames continue to be far away, the thickened section of alimiting rod can be pulled between the traveling wheels and a movable bottom plate, the movement of the running trolley is completely stopped, even if the steel wire rope is pulled off at the moment,accidents cannot occur as the running trolley is locked in place, and the safety of wire operation is improved.
本发明涉及影视道具技术领域,且公开了一种规避钢丝绳拉断的威亚运行小车,包括两个移动架,所述移动架的上端安装有行走轮,两个所述移动架通过致断螺栓固定连接,所述移动架的两侧上端均活动连接有滑块。该规避钢丝绳拉断的威亚运行小车,当两侧的电机运行不同步时,作用下会先作用在致断螺栓上,吸收过大的拉力,避免之间拉断钢丝绳,给予操作人员反应时间,同时使行走轮停止转动,使行走轮和行走轨道之间发出巨大的噪音,若没有及时停止电机,两个移动架继续远离,会将限位杆的变粗段拉入行走轮和活动底板之间,彻底停止运行小车的移动,即使此时钢丝绳拉断,运行小车锁定在原位,不会发生事故,提高威亚运行的安全性。
