The invention discloses a sand-blasting slip-reducing device for assisting train starting, which is applied to the technical field of train accessories and is characterized in that a storage hopper is arranged for storing sand, an electric control valve is arranged for controlling opening and closing of sand feeding, and the sand is discharged from the storage hopper to the position of a sand-blasting assembly through a material pipe; when the sand blasting action is needed, the air pump extracts air in the external environment and rushes out sand falling from the top material pipe, large force is provided to enable the sand to be blasted between a wheel rail and a train wheel, airflow can be blown to the surface of the wheel rail through the blowing nozzle so that rain, snow and impurities on the surface of the wheel rail can be blown away, friction between the wheel rail and the wheel rail can be prevented from being affected, and the service life of the wheel rail is prolonged. And in the spraying process, all the sand materials cannot be crushed by the train wheels, the sputtered sand materials exist in the spraying process, and a draught fan is matched with a sand returning cover through an extraction pipe, so that the sand materials can be conveniently extracted and recycled and enter a sand returning shell along a circulating pipe.

    本发明公开了一种辅助火车起步的喷砂降滑装置,应用在火车配件技术领域,本发明通过设置存放斗用于对砂料进行存放,设置的电控阀用于控制砂料投放的启闭,并且通过料管将砂料从存放斗中排放到喷砂组件的位置,在需要喷砂动作的时候,气泵抽取外部环境中的空气,并且将顶部料管下落的砂料冲出,提供较大的力使其被喷至轮轨和火车轮之间,气流通过吹嘴会将气流吹到轮轨的表面,以将其表面的雨雪和杂质吹扫,避免影响车轮和轮轨之间的摩擦,而在喷射的过程中并不会使所有的砂料都被火车轮压碎,其过程中还有溅射的砂料,风机通过抽取管配合回砂罩,可以便于对砂料进行抽取回收,并且沿着循环管进入回砂外壳中。
