The invention discloses protection equipment for metal mine underground mining, and relates to the field of mining protection equipment.The protection equipment comprises two fixing columns, sliding grooves are formed in the top ends of the two fixing columns, sliding plates are slidably installed in the two sliding grooves, and square through holes are formed in one sides of the two fixing columns in a penetrating mode; and fixing plates are arranged in the two square through holes in a sliding manner. According to the invention, the deceleration spring is elastically deformed under the force of the baffle plate 9 and converts the inertia of the mine car into the elastic potential energy of the deceleration spring, and meanwhile, the elastic potential energy is released to apply counter-acting force to the baffle plate, so that the speed attenuation after the mine car is out of control is accelerated, and finally, the mine car gradually stops under the action of the deceleration spring; the mine car out of control is intercepted, the speed reduction process of the mine car is changed into linear speed reduction, the counter-acting force to the mine car in the speed reduction process is greatly reduced, damage to the mine car is reduced, and the service life of the mine car is prolonged.
本发明公开了一种金属矿山井下采矿用保护设备,涉及采矿保护设备领域,包括两个固定柱,两个所述固定柱顶端均开设有滑槽,两个所述滑槽内部均滑动安装有滑动板,两个所述固定柱一侧均贯穿开设有方形通孔,两个所述方形通孔内部均滑动设置有固定板。本发明,减速弹簧受到抵挡板9的力发生弹性形变并将运矿车的惯性转化为减速弹簧的弹性势能,同时弹性势能释放对抵挡板施加反作用力,加快了运矿车失控后速度的衰减,最终运矿车在减速弹簧的作用下逐渐停止,完成对失控矿车的拦截,使得矿车的减速过程变为线性减速,大大减小了减速过程中对运矿车的反作用力,减小了运矿车所受到的损伤,提高了运矿车的使用寿命。
