[0002] With the increase of railway transportation demand, especially the widespread use of high-speed trains, the dependence of trains on the track during operation is more and more obvious, especially in wet, icy or bad weather conditions, ensuring the traction and braking performance of the train is the key to ensuring driving safety. In order to improve the stability and traction of the train in these special conditions, sanding operation has become one of the necessary measures. However, the traditional sanding operation method has many shortcomings, and it is urgent to improve the efficiency and accuracy through technological innovation.
[0003] Disadvantages of traditional sanding method: traditional sanding operation mostly relies on manual sand screening or uses simple trolleys for sanding, which has several outstanding problems:
[0004] 1) The quality of sand cannot be strictly controlled: the sand screening process often lacks a closed system and necessary dust removal and drying measures, resulting in impurities in the sand, affecting the sanding effect.
[0005] 2) The sanding process is not closed: in the traditional sanding process, due to the old equipment or lack of effective sealing design, dust in the sand box is easily taken out, causing dust pollution, increasing the environmental pollution and labor safety risk of the site.
[0006] 3) The sanding amount cannot be accurately counted: the traditional sanding equipment cannot count the sanding amount of each compartment in real time, making it difficult to evaluate the work efficiency and unable to effectively manage and optimize the operation.
[0007] 4) Low operation efficiency and greatly affected by human factors: due to the low sanding efficiency of traditional equipment, the sanding time is long, and it is easily affected by the skills and experience of the operators, causing unstable operation quality.

The combination with the intelligent control system in the specific implementation can adjust the sand adding amount in real time during the operation, ensure that the sand adding quality always remains within the standard range, and greatly improve the accuracy and reliability of the operation.
[0049] Please refer to Figure 5 In the embodiment, the sand storage bin 301 includes a bin body 3011, a support 3012 and side angle irons 3013. The bin body 3011 is in the shape of a trapezoidal hopper. The support 3012 is arranged at the lower side of the bin body 3011 and is fixed on the lifting platform 203 by screws. The side angle irons 3013 are installed at the rear end of the support 3012. The side angle irons 3013 are provided with L-shaped adjusting grooves 3014. The bin body 3011 is provided with sliding shafts arranged at the two sides of the bin body 3011 and extending into the adjusting grooves 3014. The bin body 3011 is provided with limiting columns 3016 at the rear end. The support 3012 is provided with a clamping rod 3015 arranged rotatably and limiting the limiting columns 3016 by the clamping grooves on the clamping rod 3015. The angle of the bin body 3011 can be changed by adjusting the position of the sliding shafts in the adjusting grooves 3014, so that the bin body 3011 can be inclined to a suitable angle to facilitate the loading operation.
[0050] The embodiment also provides a use method of the sand adding vehicle, which includes the following steps.
[0051] 1) Moving the vehicle 1 out of the preparation field: The operator controls the power wheels of the vehicle 1 by the steering wheel to move the vehicle 1 out of the preparation field. Since the battery compartment 104 is designed in front, the vehicle 1 has a low body height and high flexibility, which can be moved smoothly in a limited space, ensuring smooth operation.
[0052] 2) Opening the sand storage bin 301 for loading: The operator opens the top cover 304 of the sand storage bin 301, loosens the clamping rod 3015, moves the sliding shafts at the side end of the bin body 3011 along the adjusting grooves 3014, adjusts the inclination angle of the bin body 3011, and makes the bin body 3011 better for loading operation.
[0053] 3) Adjusting the height of the lifting platform 203: After moving the vehicle 1 to the operation position, the operator adjusts the height of the lifting platform 203 through the control panel to make the sand adding gun head accurately dock to the sand adding port of the target carriage. The design of the lifting system can adapt to trains of different heights, and can flexibly adjust the platform height when operating in a small space, ensuring efficient sand adding process.
[0054] 4) Start the screening and dust collection drying module 302: Before sanding, the operator starts the screening module (vibrating screen) to remove impurities in the sand, and at the same time starts the dust collection and drying module 302 (including dust collector and drying fan) to remove moisture and dust in the sand, ensuring that the sand quality meets the standard.
[0055] 5) Start the sand conveying system for sanding operation: the operator starts the air pump, which conveys the screened and dried sand to the sanding gun head through the sand conveying pipe. The air pressure system ensures that the sand is delivered to the car in a stable flow.
[0056] 6) Monitor the sanding amount and flow: During sanding, the sand storage bin 301 and the sand conveying pipe are provided with pneumatic conveying flow meters and weighing sensors to monitor the weight and flow changes of the sand in real time, ensuring that the sanding amount of each car meets the requirements, and ensuring that the sanding quality is always within the standard range.
[0057] 7) End the operation and fold up the equipment: After completing the sanding operation, the operator turns off the sanding system and retracts the lifting platform 203. The lifting platform 203 is driven back to the most compact state by the electric cylinder 202, reducing the space occupation of the equipment. The operator moves the trolley 1 back to the original position or drives it to the next operation area to ensure efficient use of the equipment.
[0058] 8) Maintenance and inspection: After the operation is completed, the operator performs daily inspection and maintenance of the equipment.
[0059] It is worth noting that: the entire device is controlled by the overall control system, and since the control system matches common devices, it belongs to existing mature technology, and the electrical connection relationship and specific circuit structure are not described here.
