Abstract

The invention discloses an automatic sanding device for an electric locomotive. The automatic sanding device comprises a sealing plate and a sand storage box, wherein the upper part of the sand storage box is of a cuboid shape, the lower part of the sand storage box is of a tapered funnel shape, a circular through hole is formed in the middle part of a bottom plate of the sand storage box, the bottom plate of the sand storage box is connected with a top plate of a temporary sand storage case and the top part of one side of a protective plate, the other side of the protective plate is fixedly connected with a motor, below the protective plate, the side surface of the motor is fixedly connected with a spring, the inner side of the spring surrounds a dowel bar which is connected with the motor and penetrates through the temporary sand storage case transversely, the spring is fixedly connected with a side plate of the temporary sand storage case, and a sealing plate matched with a circular opening in the top plate of the temporary sand storage case is fixedly arranged on the dowel bar. The automatic sanding device for the electric locomotive, which is disclosed by the invention, can effectively prevent sand dropping and leakage, and is simple and reliable in structure, low in manufacture cost and high in safety.

Description

technical field [0001] The invention relates to a mine sand spreading device, in particular to an automatic sand spreading device for an electric locomotive. Background technique [0002] At present, the existing railway locomotives can safely brake during operation. Usually, a sand spreading device is installed on the four corners of each bogie of the locomotive. The sand spreading device can spread sand between the wheels and the rails, increasing the The adhesion between the two prevents the wheel from slipping and the surface of the wheel hub from being scratched; ideally, a constant amount of sand should be spread per meter of travel, if too much or too little sand is spread, it will not be optimal anti-skid effect. Therefore, under the premise of ordinary sand spreading control devices, it is necessary to control the amount of sand spreading to minimize sand loss and sand leakage, so as to prevent accidents. [0003] The existing sand spreading device has problems su...
