The invention relates to the technical field of mine auxiliary equipment, and discloses a rope winch capable of preventing sliding down. The rope winch capable of preventing sliding down comprises a base. A motor, an equipment box, a first baffle and a second baffle are sequentially arranged at the upper end of the base, the output shaft end of the motor is fixedly connected with a transmission shaft, the middle of the transmission shaft is fixedly connected with a reel, and one end of the transmission shaft is fixedly connected with a large helical gear. Through the arrangement of a brake mechanism, when the motor rotates in the forward direction for winding, an impeller rotates in the forward direction with the transmission shaft. Under the action of the arc surface of the impeller, a spring is compressed and a limiting block is retracted into an installation cavity, the normal winding of a steel wire rope is not affected, when the sliding down and unwinding occur due to the misoperation of others or the weight of the steel wire rope, the transmission shaft turns, at the moment, the flat end of one side of the impeller abuts against the limiting block, and the impeller and the transmission shaft stop rotating to prevent the phenomenon of sliding down and unwinding; and meanwhile, a roller can reduce the contact friction between the limiting block and the impeller, and the service life of the limiting block is prolonged.

    本发明涉及矿井辅助设备技术领域,且公开了一种防跑车的钢丝绳绞车,包括底座,底座的上端依次设置有电机、设备箱、第一挡板、第二挡板,电机的输出轴端固定连接有传动轴,传动轴的中部固定连接有卷筒,传动轴的一端固定连接有大斜齿轮。通过制动机构的设置,当电机正向旋转进行收卷时,叶轮随着传动轴正向旋转,在叶轮弧面的作用下会压迫弹簧并使限位块收缩进安装腔中,不会对钢丝绳的正常收卷造成影响,当因为他人误操作或者钢丝绳自身重量作用下发生放卷跑车时,传动轴会发生反转,此时叶轮一侧平面端将会抵住限位块,使得叶轮及传动轴停止转动,防止出现放卷跑车的现象,同时滚轮可以减小限位块与叶轮的接触摩擦力,延长限位块的使用寿命。
