The invention discloses an anti-running-grinding safety protection device. Shells on the two sides are connected through connecting bolts, and a steel wire rope is arranged in a gap between the shellson the two sides; and rolling wheels are arranged in a mounting groove and make contact with the steel wire rope, and first sliding grooves are formed in the upper side and the lower side of the mounting groove and are obliquely arranged in the direction from left to back to right to front. The invention further discloses a winching with the anti-running-grinding safety protection device. The winching comprises a base, vertical plates arranged on the two sides of one end of the base, a second rotating shaft arranged between the vertical plates on the two sides, a winding drum arranged outsidethe second rotating shaft in a sleeving mode and the anti-running-grinding safety protection device. When the winching normally works, the rolling wheels make contact with the steel wire rope, when the winching runs away, the steel wire rope reversely moves, the rolling wheels slide to the other sides of the first sliding grooves under the guiding effect of the first sliding grooves under the friction force of the steel wire rope, and thus the distance between the rolling wheels on the two sides is decreased; and meanwhile, the rolling wheels generate extrusion force on the steel wire rope, and thus the winching is prevented from running away.
本发明公开了一种防跑磨安全保护装置,两侧的壳体通过连接螺栓连接,钢丝绳设置在两侧壳体的间隙内部;滚轮设置在安装槽内部,且滚轮与钢丝绳相接触,安装槽的上下两侧设有第一滑槽,第一滑槽由左后向右前方向倾斜布置。本发明还公开了一种具有防跑磨安全保护装置的绞磨,包括底座、设置于底座一端两侧的立板、设置与两侧立板之间的第二转轴、套设于第二转轴外部的卷筒以及上述的防跑磨安全保护装置。本发明正常作业时,滚轮与钢丝绳接触,绞磨跑磨时,钢丝绳反向窜动,滚轮受钢丝绳的摩擦力在第一滑槽的导向作用下滑向第一滑槽的另一侧,使两侧滚轮的间距减小,同时滚轮对钢丝绳产生挤压力,从而避免了绞磨跑磨。
