Laser cleaning equipment and a cleaning method for a shaft component are provided. The equipment includes: a supporting base assembly; two driving wheel structures on the supporting base assembly, driving wheels of each of which is configured for being close to or away from each other, and the shaft component to be cleaned is placed between the two driving wheel structures; a friction wheel structure that is tangent to driving wheel structure(s) and uses a friction force thereof to drive driving wheel structure(s) to rotate; a connection shaft assembly that coaxially passes through the friction wheel structure; a power driving mechanism, one end of which that faces toward the connection shaft assembly is in drive connection with the connection shaft assembly and is configured to drive the connection shaft assembly to rotate; and a laser cleaning mechanism configured for performing laser cleaning on the shaft component to be cleaned.

The invention relates to a device for automatic dispensing of a maintenance agent, such as an anti-icing agent or a de-icing agent, on specific parts of a rolling stock travelling on a railway track. The device comprises a dispensing unit, a detection unit configured to generate a detection signal before said rolling stock reaches the dispensing unit, a sensor unit configured to determine position and velocity of the rolling stock, and a control unit. The control unit is configured to receive said detection signal from said detection unit, determine a dispensing schedule based on said rolling-stock velocity, and transmit a control signal to the dispensing unit to control said dispensing unit based on said dispensing schedule. Furthermore, the present inventive concept also relates to an associated method.
