Description

Portable sand feeding device for locomotive sand box

Technical Field

The utility model relates to the technical field of locomotive sand boxes, in particular to a portable sand feeding device for a locomotive sand box.

Background

The railway locomotive runs on the steel rail, and mainly pulls the whole train by the friction force between the driving wheel of the locomotive (locomotive) and the steel rail. While the drive wheels of locomotives are typically only six pairs, the friction force required (the railroad designation "adhesion") is quite large. The steel rail and the wheels are made of steel, the surface is smooth, and in certain situations (such as bad weather like rain, frost, snow, fog and the like or when the train takes emergency braking), the situation that the adhesion force is smaller than the traction force of the locomotive and the idling happens can occur, and sand needs to be sprayed on the rail surface to improve the adhesion coefficient. The locomotive sand box is an important accessory of a locomotive, and is used for storing a large amount of (900 kg) special quartz sand for the locomotive, when the locomotive runs idle or is braked urgently, a locomotive driver can properly reduce output power according to the running condition of the locomotive and simultaneously cooperate with the locomotive driver to carry out manual sand spraying, so that the adhesive force between the locomotive and a wheel rail is increased, idle running stop of a train is prevented, the rail is prevented from being injured by a crashing way, or the emergency braking distance is shortened, and driving safety is ensured.

Because the large locomotive sand adding equipment occupies large area and has high cost, manual sand adding is usually adopted for locomotive preparation in a small-scale working section or a turning section (two workers lift sand bags beside a locomotive and send the sand bags to a locomotive sand box by using a shovel). However, manual sand feeding has the problems of low working efficiency and high labor intensity; moreover, sand is easy to spill in the sand adding process, waste or ground pollution is caused, the ground is cleaned after the sand adding operation is finished, and the secondary labor of ground cleaning work is increased.
