Description
Technical field
The present invention relates to locomotive technology field, specially a kind of locomotive sandbox.
Background technique
The locomotive used on railway at present, no matter electric locomotive or diesel locomotive, their sandbox is required to one one
A manual opening sandbox end cap checks husky amount.According to operation or work standard, range estimation reaches sandbox capacity 2/3rds with top for qualification.
The sandbox of one locomotive few then eight, more then 16, the above-mentioned obvious efficiency of way is too low.And in traveling locomotive sandbox on the way
Sand amount is not reflected on locomotive console in real time, this makes engine drivers in locomotive depot that can not learn the sand that sandbox stores on the way in traveling
Amount；When stop-for-waiting routine examines vehicle, if being parked in the side for interior high platform of standing, since platform is higher, close to platform side
EEF bogie, which can not be checked or be closed on main track side not, allows the security regulations such as inspection vehicle to obtain engine drivers in locomotive depot can not
The interior husky amount stored of sandbox is known, so that the husky service condition measured and timely gaza can not be grasped.Locomotive is in operation on the way by spreading
Sand is to increase the adhesion between wheel tread and rail, to prevent from dallying and slide, especially the weather such as storm wind sleet are disliked
Slightly location is even more so, and at this time if husky amount is insufficient, consequence will be hardly imaginable；Locomotive is in braking by sanding to assist making
It is dynamic, original stucco module by wind pressure effect and lower sand, in the case that wind pressure is certain, deposit it is husky to measure the amounts of sanding fewer more, it is this
The non-uniform phenomenon of the amount of sanding does not have the effect preferably to sand, combines to can not preferably reach air damping with sanding
Braking maneuver method.This is clearly a kind of defect.
But locomotive sandbox has the disadvantage that in the prior art
