It is currently widely used in the transportation of bulk materials such as coal and ore in stockyards, terminal transfer base stations, etc. Train carriage unloading usually uses train tippers, chain bucket unloaders, vertical screw unloaders, etc. The above unloading methods have problems such as incomplete unloading and residual materials. With the continuous improvement of the country's environmental protection requirements, in order to avoid dust caused by unloading carriages during driving, many places and enterprises have issued a series of regulations. After unloading, the weight and volume of materials remaining in the carriage of bulk material transport trains shall not exceed a certain range, and the cleanliness of the carriage should be maintained. Therefore, it is necessary to remove the residual materials in the train carriage.

[0003] The currently commonly used methods for removing debris from train carriages have the following problems: one method is to open the side door of the carriage for manual cleaning, and sweep the debris in the carriage to both sides of the track. This cleaning method is not only inefficient, but also easily causes secondary pollution. The manual operation time is long, the labor intensity is high, and the risk is extremely high, which affects the efficiency of removing debris from train carriages.

[0078] Step 1. In the central control room, a start command is issued to the crawler train carriage mobile cleaning device, and the crawler train carriage mobile cleaning device starts from the parking area, and the carriage position information is determined by the high-precision combined navigation and positioning module to put the crawler train carriage mobile cleaning device in place;

[0079] Step 2. Confirm that the crawler train carriage cleaning device is in normal condition, tow the train carriage after the tipping machine or unloading machine process to the designated cleaning position, check that the system working indicator light is operating normally, and then the crawler train carriage cleaning device executes the working instruction;

[0080] Step 3. The sensor of the crawler train carriage mobile cleaning device identifies the carriage exterior number and carriage model, and transmits the identification information to the control unit 6;

[0081] Step 4. The cleaning mechanism 4 moves to the end position of the train carriage, the lifting mechanism 3 works, the second motor 32 drives the gear 33 to rotate forward, so that the cleaning mechanism 4 descends, and the height sensor and pressure sensor at the bottom of the cleaning mechanism 4 feed back the distance between the bottom of the carriage and the cleaning mechanism 4 in real time and transmit it to the control unit 6. When the auxiliary wheel 46 contacts the bottom of the carriage, the cleaning mechanism 4 stops descending;

[0082] Step 5. The control unit 6 sends a work instruction to the cleaning mechanism 4, and the driving motor drives the side roller brush 431, the side sweeping disc 441, the bottom roller brush 432, and the bottom sweeping disc 442 to start rotating, and the fan 53 starts working. The crawler walking mechanism 1 controls the driving speed according to the material remaining amount fed back by the industrial camera and the image processor, and moves forward;

[0083] Step 6. The crawler traveling mechanism 1 moves, and the crawler train carriage mobile cleaning device as a whole reciprocates along the track, and the cleaning mechanism 4 and the negative pressure adsorption system 5 remove the residual materials in the train carriage and collect them into the collection bin 52;

[0084] Step 7. After the in-carriage collection system identification system confirms that there is no residual material in the car, the crawler walking mechanism 1 stops moving, the second motor 32 drives the gear 33 to rotate in the opposite direction, and the lifting mechanism 3 drives the cleaning mechanism 4 to rise and leave the car;

[0085] Step 8. The crawler walking mechanism 1 moves to the next carriage, and steps 3 to 7 are repeated to clean the next carriage;

[0086] Step 9. After the cleaning task is completed, the crawler walking mechanism 1 travels to the material collection area, opens the discharge port of the discharge machine at the bottom of the aggregate bin 52, and unloads the material in the aggregate bin 52. After the unloading is completed, the crawler walking mechanism 1 leaves the material collection area, returns to the parking area and closes.
