Abstract

This invention discloses a ballast storage and backfilling device and method for intelligent ballast distribution cars, relating to the field of railway engineering machinery technology. It includes a ballast storage hopper, an inclined conveying mechanism, a transverse conveying mechanism, and a ballast distribution trolley. The inclined conveying mechanism collects ballast collected from the slope by the intelligent ballast distribution car and lifts it obliquely to the storage hopper.

[0025] The present invention also provides a method for backfilling ballast based on the above-mentioned device, comprising the following steps:

[0026] Step S1. The first hopper of the inclined conveyor receives the ballast collected from the slope by the intelligent ballast distribution vehicle;

[0027] Step S2. The ballast is lifted and transported to the ballast storage hopper by the conveyor belt of the inclined conveyor mechanism for storage or backfilling;

[0028] Step S3. The ballast is thrown to both sides of the line through the ballast throwing channel and the lateral conveying mechanism of the ballast storage hopper; or it is diverted through the backfilling channel 1 and backfilling channel 2 of the ballast storage hopper and then flows into the center channel, side channel 1 and side channel 2 of the ballast distribution hopper.

[0033] The beneficial effects of this invention are as follows:

[0034] During intelligent ballast distribution car operations, this ballast storage and backfilling device utilizes a technical solution to transport excess ballast collected from the slope at an angle to a storage bin. Then, a transverse conveyor belt throws the excess ballast from the storage bin to either side of the track or, via a ballast distribution trolley, precisely backfills it into the four pick holes and the center of the track for the tamping machine, completing the mechanized and automated shaping of the ballast. The gate design enables the storage bin to store ballast; the gate, ballast distribution device, ballast detection device, and corresponding channels allow for adjustable and controllable ballast at each pick hole and the center of the track; the ingenious structural design and arrangement of the ballast distribution trolley achieves the predetermined precise backfilling and shaping of the ballast while ensuring smooth vehicle retrieval and locking within the railway clearance. This invention overcomes the technical shortcomings of existing ballast backfilling devices, such as limited ballast storage capacity, extensive ballast backfilling, slow ballast shaping speed due to purely manual methods, low work efficiency, high labor intensity, and high operational safety risks.
