first, an operator controls the lifting assembly 12 to move the door 121 along the Z-axis direction, so as to open the working channel 13, the locomotive wheelset 100 rolls along the Y-axis direction on the locomotive track 6, enters the cleaning chamber 1 through the working channel 13, and stops the locomotive wheelset 100 on the cleaning station through the stopping action of the stopping assembly 91 on the locomotive wheelset 100.

Step two, cleaning operation:

the operator controls the lifting assembly 12 to close the operation channel 13, so that the locomotive wheel pair 100 is located in a relatively closed space, when the stopping assembly 91 cancels the stopping effect on the locomotive wheel pair 100, the shifting assembly 92 drives the locomotive wheel pair 100, the locomotive wheel pair 100 starts to rotate around the axis direction of the locomotive wheel pair 100, the operator starts the high-pressure plunger pump to extract the cleaning liquid in the water collection tank 3, the cleaning liquid is filtered by the fine filter 5, then is sprayed out through the spray pipe 24 and the spray nozzle 241 on the mechanical arm 22, and then the servo motor is controlled to be electrified through the electric control cabinet, so that the cleaning robot 2 can drive the spray pipe 24 and the spray nozzle 241 to move on a preset movement track, and further the multi-azimuth multi-angle cleaning operation of the locomotive wheel pair 100 is realized.

The second step further comprises the following steps:

when the locomotive wheelset 100 performs automatic cleaning operation, the used cleaning liquid enters the water collection tank 3 through a funnel-shaped water collection tank, a diaphragm pump and a screw pump are respectively started before the cleaning liquid is filtered by a fine filter 5, the cleaning liquid with more oil content on the upper side of the inside of the water collection tank 3 is pumped to an oil-water separator 412 for oil-water separation operation by pumping, the separated oil liquid is scraped by a scraper and discharged out of the water collection tank 3, and the separated water liquid flows back into the water collection tank 3 for reuse; simultaneously, impurities such as sediment at the bottom side inside the water collection tank 3 are pumped by the screw pump, so as to be pumped to the filter press for solid-liquid separation operation, the filtered sediment is pressed into mud blocks to be discharged, and the filtered water liquid returns to the water collection tank 3 again through the water return pipe 43, so that rough filtration operation before fine filtration of cleaning liquid is realized.

Step three: pushing:

after the cleaning operation of the standby wheel set 100 is completed, the operator manipulates the lifting assembly 12 to open the operation channel 13, and the pushing assembly 93 pushes the wheel set 100 out from the output side of the wheel set displacement mechanism 9, so that the wheel set 100 is pushed out of the cleaning chamber 1, and the cleaning chamber 1 waits for the next wheel set 100 to perform the cleaning operation.

The wheel set cleaning device provided by the application can ensure that the wheel set 100 is cleaned in a relatively closed space by arranging the cleaning chamber 1, so that cleaning liquid is prevented from splashing in an open space, automatic cleaning operation of the wheel set 100 can be realized by arranging the cleaning robot 2, the problem that manual operation is time-consuming and labor-consuming in the past is solved, the water collection tank 3 is arranged, the cleaning chamber 1 can be ensured to timely discharge sewage, the cleanliness of the cleaning operation space is favorably maintained, the filter residue oil filtration treatment can be carried out on cleaning liquid after the automatic cleaning operation by arranging the coarse filtration mechanism 4, the cleaning liquid is reused, the cost is saved, fine filtration can be carried out on the cleaning liquid by arranging the fine filter 5, the cleaning effect of the wheel set 100 is improved, the influence of impurities on normal operation by the nozzle 241 is avoided, the reliability of the cleaning operation is further improved, and the cleaning effect is better.
