The invention relates to the technical field of roadway winches, in particular to a coal mine roadway winch with a slack rope protection mechanism, which comprises a roadway winch body, a protection seat is arranged below the roadway winch body, a slack rope protection assembly is arranged on the protection seat, and the slack rope protection assembly comprises two groups of pushing plates. A trapezoidal abutting seat is mounted on one side of the pushing plate through a trapezoidal mounting seat, and a damping type reinforcing assembly is arranged on the trapezoidal abutting seat; the protection base is combined with the rope loosening protection assembly, sudden stop after falling of the protection base is achieved firstly, then inertia falling of the roadway winch body is utilized, a piston plate is forced to compress air in a buffer spring and the protection base, and the roadway winch body is effectively buffered; a damping type reinforcing assembly is combined, secondary fixing of the position of the protection base after sudden stop is achieved, and the inertia acting force applied to the protection base by the roadway winch body is eliminated; and meanwhile, the ascending and resetting speed of the piston plate is reversely slowed down, and secondary injury to personnel caused by rapid ascending of the piston plate is eliminated.
本发明涉及巷道绞车技术领域,尤其涉及一种带有松绳保护机构的煤矿巷道绞车,包括巷道绞车本体,巷道绞车本体的下方设置有保护座,保护座上设置有松绳保护组件,松绳保护组件包括两组推动板,且推动板的一侧通过梯形安装座安装有梯形抵接座,梯形抵接座上设置有阻尼式加固组件;本发明通过保护座结合松绳保护组件,先实现保护座发生坠落后的急停,再利用巷道绞车本体的惯性下坠,迫使活塞板压缩缓冲弹簧与保护座内的空气,对巷道绞车本体进行有效缓冲;后结合阻尼式加固组件,实现保护座急停后位置的二次固定,消除巷道绞车本体对保护座施加的惯性作用力;同时反向减缓活塞板上升复位的速度,消除活塞板快速上升对人员造成的二次伤害。
