The invention belongs to the technical field of rail transit braking, and particularly discloses a high-speed rail sand box sand adding device which comprises a conveying channel and a power device, the power device comprises a first conveying belt running circularly, and magnetic assemblies are distributed on the first conveying belt; the conveying channel is close to the outer ring of the first conveying belt; a second conveying belt is connected in the conveying channel end to end along the conveying channel and can slide relative to the inner wall of the conveying channel. Ferromagnetic materials are distributed on the second conveying belt, can be attracted by the magnetic assembly at intervals of the conveying channel wall and move along with the magnetic assembly. The second conveying belt is used for conveying gravels. The problems that an existing high-pressure air pump type automatic sand feeding machine easily causes serious air pollution, and pipelines, pump bodies, valves and the like used for conveying gravel are seriously abraded and cannot be used due to various damages after being used for a period of time are solved.

    本发明属于轨道交通刹车技术领域,具体公开了一种高铁砂箱加砂装置,包括输送通道和动力装置,动力装置包括循环运行的第一传送带,第一传送带上分布有磁性组件;输送通道贴近第一传送带外圈,首尾相连;输送通道内沿输送通道首尾相连有第二传送带,第二传送带与输送通道的内壁可相对滑动;第二传送带上分布有铁磁性材料,能够间隔输送通道壁被磁性组件吸引并跟随磁性组件移动;第二传送带用于输送砂砾。本发明解决了现有的高压气泵式自动上砂机容易造成严重的空气污染,而且,用于输送砂砾的管道、泵体、阀门等磨损严重,在使用一段时间后都发生各式各样的损坏而无法使用的问题。
