Description
Technical Field
The utility model belongs to the field of vehicle bottom cleaning devices of tippers, and particularly relates to an intelligent vehicle bottom cleaning device of a tipper and a cleaning method thereof.
Background
The dumper is a main dumper for transporting ores and other materials by trains. In the unloading process, the dumper clamps and overturns the railway wagon, the materials in the carriage are dumped into the unloading hopper, and the materials are transported by the transport belt arranged below the unloading hopper. In the overturning and dumping process, as the overturning angle of the dumper is about 170 degrees, materials in a carriage generally have a certain residual after dumping, and when the moisture content of the materials is large or the materials meet rainy and snowy weather in the transportation process, the residual quantity of dumped railway wagon materials is more. If the residual materials in the carriage are not cleaned, economic loss is caused, and the requirements of railway departments on the management of the railway carriage are not met, at present, the cleaning mode of the residual materials in the carriage is mainly manual cleaning, and a few of the residual materials are sucked away by using high-pressure air to sweep (utility model CN 207013413U) or using a hinged loose sucking cleaner which is movably connected to extend into the carriage and using negative pressure through staff (utility model CN 204342007U).
The prior art cleaning solutions have more or less the following drawbacks:
1. the manual cleaning work efficiency is low, the labor intensity is high, and dangerous and harmful factors such as dust, noise and the like on the working site bring great influence to the occupational health of on-site workers. Manual cleaning is in order to keep the timeliness of cleaning, and cleaning personnel need constantly climb the carriage that is in the mobile state, and job site security risk is higher.
2. The utility model CN207013413U is characterized in that the high-pressure gas is used for blowing by a special tool held by a worker, so that dust emission on the working site is larger, and occupational health hazard to the worker is larger. The special cleaning tool has the length of about 2.5 meters, the operation convenience is insufficient, and the labor intensity of manual operation is still not small. When a strong or large block of residue material is encountered, the cleaning effect and working efficiency are not ideal enough.
3. The hinged loose suction cleaner (CN 204342007U) is movably connected and stretches into a carriage to suck residual materials by utilizing negative pressure, but has insufficient adaptability to large residual materials, and when the materials with strong cohesiveness are encountered, the pipelines are easy to be blocked, the maintenance convenience is insufficient, and the cleaning efficiency of the residual materials is also influenced. The sucked materials need to be transferred for the second time after entering the storage hopper, so that the production cost is increased.
