[0002] Railway rails are primarily used on railways, working in conjunction with switches to allow trains to move forward continuously without needing to turn. Typically, a railway track consists of two parallel steel rails fixed to sleepers, beneath which lies the ballast. Furthermore, the geometry, relative positions, and basic dimensions of various parts of the railway track, such as gauge, levelness, elevation differences, and alignment, are all crucial, collectively guiding locomotives and rolling stock and bearing their various loads.

Furthermore, the integration of cleaning and chemical spraying is insufficient, with sweeping and chemical spraying often being separate operations requiring multiple devices or manual assistance, resulting in a cumbersome process and significantly reduced maintenance efficiency. Moreover, uneven mixing of cleaning agents and their tendency to settle after addition lead to inconsistent cleaning effects and an inability to effectively remove stubborn stains.

[0023] Working principle: When using this device, the operator holds the handlebars and pushes the equipment along the rail transit line, adjusting the position to ensure the cleaning brush is aligned with the track surface and the area to be cleaned. The first drive motor is started, and power is transmitted through the first drive gear to the first transmission rack. The first transmission rack drives the first drive gear to rotate, which in turn drives the cleaning brush to rotate at high speed, beginning the cleaning of dust and debris from the track surface, crevices, and surrounding areas. The drive shaft moves the baffle to a suitable angle to prevent dust and debris from splashing during cleaning, ensuring a clean working environment. The second drive motor is then started, transmitting power to the second drive gear, which drives the second transmission rack to rotate, thus rotating the two stirring rods. The synchronous rotation ensures uniform stirring of the cleaning agent in the spray tank, preventing sedimentation. After thorough stirring, turning on the switch releases the agent through the transmission section, transmission pipe, and connecting elbow into the spray pipe. The agent is then evenly distributed to each spray head via the diverter pipe, atomizing and spraying onto the track surface and surrounding area, working in sync with the sweeping brushes. During operation, the position of the sweeping brushes can be finely adjusted by sliding the sliding seat along the groove according to the track width and cleaning needs. Adjusting the drive motor speed adapts to different levels of soiling. The agent spray flow rate can be adjusted via the switch to regulate the spray volume based on the soiling condition. If the spray range needs adjustment, the spray head angle can be adjusted via the rotating frame to achieve omnidirectional coverage.
