Railway tunnel portal rockfall prevention equipment
The railway tunnel portal rockfall prevention equipment comprises a machine body shell, an intercepting cavity with an upward opening is formed in the machine body shell, a discharging opening penetrating through the right surface of the machine body shell is formed in the bottom wall of the intercepting cavity, and cross beams which are symmetrical in left-right position and fixedly connected with the intercepting cavity are arranged in the intercepting cavity; a rotating cavity with an upward opening and penetrating through the left and right surfaces of the cross beam is formed in the cross beam; the jacking block can be quickly pushed out when the air bag deforms due to stone smashing to achieve the effect of receiving the upcoming stone impact, the first spring can be compressed to achieve the effect of buffering and absorbing the stone impact force, meanwhile, when the jacking block is pressed down, air in the jacking cavity can be pressed back into the high-pressure air cavity again, and the air in the high-pressure air cavity can be separated from the high-pressure air cavity. The effect of inflating the high-pressure air cavity can be achieved, the strength of the air bag is improved, and the impact force of more stones is absorbed.
本发明公开了一种铁路隧道口防落石设备，包括机体外壳，机体外壳内设有开口向上的拦截腔，拦截腔底壁设有贯穿机体外壳右表面的排料口，拦截腔内设有左右位置对称且与拦截腔固定连接的横梁，横梁内设有开口向上且贯穿横梁左右表面的转动腔；本发明设有的顶升块能在气囊受到石头砸击变形时被快速推出，起到迎接即将到来的石头撞击的作用，而第一弹簧能被压缩，起到缓冲吸收石头冲击力的作用，同时顶升块被压下时，能将顶升腔内的气体重新压回高压气腔内，能起到为高压气腔充气的作用，增加气囊的强度吸收更多石头的冲击力。
