The invention relates to the technical field of railway vehicles, and particularly discloses a sanding pipe connecting device and a sanding unit.The sanding pipe connecting device comprises a mounting base, a flow guide disc rotationally arranged on the mounting base, a connector located below the flow guide disc and a flexible part connecting the flow guide disc and the connector; a vertically-through sand shakeout opening is formed in the flow guide disc, a sand shakeout channel communicated with the sand shakeout opening is formed in the connector, and the sand shakeout opening comprises a funnel-shaped flow guide part formed in the mode that the top face of the flow guide disc is concavely arranged. According to the sanding pipe connecting device and the sanding unit provided by the invention, the joint can swing to a certain degree relative to the rotating axis of the flow guide disc under the condition of rotating along with the flow guide disc, so that the stress at the joint of the sanding pipe and the joint can be reduced, and the connection between the sanding pipe and the joint is prevented from loosening or falling off.

    本发明涉及轨道车辆技术领域,具体公开了一种撒砂管连接装置和撒砂单元,撒砂管连接装置包括安装座、可转动地设置于所述安装座上的导流盘、位于所述导流盘下方的接头、连接所述导流盘和所述接头的柔性件,所述导流盘内形成有上下贯通的落砂口,所述接头内具有与所述落砂口连通的落砂通道,所述落砂口包括自所述导流盘顶面凹设形成的呈漏斗状的导流部。本发明提供的撒砂管连接装置和撒砂单元中,接头在能够跟随导流盘进行转动的情况下,还能相对导流盘的转动轴线做一定程度的摆动,如此,可减小撒砂管和接头连接处的应力,防止撒砂管和接头之间连接的松动或脱落。
