The mine vehicle spraying, cooling and speed reducing device comprises a brake disc, a sealing box, a water return pipe and a three-way adjusting valve, a clamping box is installed outside the brake disc, the exterior of the clamping box communicates with a water conveying pipe, and the end, away from the clamping box, of the water conveying pipe communicates with a water storage tank; the end, away from the driving wheel, of the rotating shaft penetrates through the outer wall of the sealing box and is connected with a center shaft of the turbine fan, the interior of the sealing box communicates with a second adjusting valve, and the end, away from the sealing box, of the second adjusting valve communicates with the interior of the clamping box. The water flow can be heated by utilizing the temperature of the brake disc, and the turbine fan is used for boosting, increasing the boiling point of the water flow and increasing the temperature of the water flow to the temperature close to that of the brake disc, so that internal stress generated by temperature difference is reduced when the water flow is lased on the brake disc, and the service life of the brake disc can be prolonged while cooling is achieved; and excessive wear is reduced.
本发明公开了一种矿山车辆喷淋降温减速装置,包括刹车盘、密封盒、回水管和三通调节阀,刹车盘的外部安装有卡接盒,卡接盒的外部连通有输水管,输水管远离所述卡接盒的一端连通有存水罐,转轴远离所述驱动轮的一端贯穿所述密封盒的外壁且与涡轮扇的中心轴连接,密封盒的内部连通有第二调节阀,第二调节阀远离所述密封盒的一端与卡接盒的内部相连通,在当刹车盘连续重刹且温度上升到过高的温度时,还可以利用刹车盘自身的温度将水流进行加热,并利用涡轮扇进行升压,提高水流的沸点,将水流的温度上升到与刹车盘接近的温度,从而在水流激射到刹车盘上时减少温差产生的内应力,达到冷却的同时还可以延缓刹车盘的使用寿命,减少过度磨损。
