Description

Technical Field

[0001] This utility model belongs to the field of train maintenance, specifically relating to a sand measuring device for train testing. Background Technology

[0002] During train operation, the wheels and rails gradually become smooth due to long-term friction. While this smoothness improves ride comfort, it significantly reduces friction during starting, braking, or climbing in rainy or snowy weather. If the locomotive spins, the wheel treads can peel off, potentially leading to rail deformation or breakage, and increasing the risk of loss of control. This is where the sandbox system becomes crucial. A key component of locomotive anti-skid technology, the sandbox system cleverly incorporates specialized sandboxes containing rigorously selected and processed anti-skid materials along the direction of wheel travel. When the train needs to increase friction between the wheels and rails, a specially designed sandblasting system quickly activates, spraying sand with a specific particle size, typically within the two to three millimeter range, onto the rails. By spraying sand, the sandbox system rapidly fills the gaps between the wheels and rails, increasing the roughness of the contact surface and significantly improving friction, ensuring stable train operation.

[0003] Excessive sand spraying will lead to waste of sand and gravel, while insufficient spraying will often cause trains to start unsuccessfully. Therefore, it is often necessary to test the sandblasting system of the sand box system in advance, measure the weight of the sprayed sand and gravel, and then determine whether the sand box system can work perfectly. However, it is often difficult to collect the sprayed sand and gravel, so there is an urgent need to design a device that can collect and support the sand and gravel. Utility Model Content
