Description

A carriage for railway transportation of ore powder

technical field

The invention relates to the technical field of mine railway transportation, in particular to a carriage for railway transportation of ore powder.

Background technique

Railway transportation is one of the main ways for mining enterprises to transport ore and mineral powder. At present, the commonly used carriages for mine railway transportation are general-purpose gondola cars. The carriages are straight up and down cuboid structures, and generally the sides of the carriages are provided with lower side doors to facilitate manual or mechanical loading and unloading operations. This carriage mainly exists following defect when transporting ore powder:

1) Mineral powder is easy to leak from the gap of the lower side door of the carriage, causing environmental pollution and loss of mineral powder. For this reason, the current existing method is usually to seal the lower side door with sealant, which is labor-intensive and time-consuming;

2) The straight-up and straight-down rectangular parallelepiped compartment is not conducive to the tipping and unloading operation of the dumper, which often causes the ore powder in the compartment to easily form cargo accumulation at the root due to the small turning angle, resulting in unclean unloading of the ore powder and a low unloading rate of the goods;

3) It is necessary to manually clean up the unloaded ore powder from the dumper, which not only increases the production operation time, but also increases the labor intensity of the workers, and also increases the safety hazard;

4) General gondola wagon has complex structure, heavy weight, small loading tonnage and small load factor;

5) There is no drainage port, which is affected by the corrosion of corrosive water in the transported mineral powder, resulting in a short service life.
