Abstract

The invention provides a rail grinding dust-precipitating system and a rail grinding wagon. The system comprises a grinding device and a dust precipitating device, wherein the dust precipitating device is arranged above the grinding device; the grinding device comprises a box body, a plurality of grinding heads and feeding mechanisms for controlling grinding angles of the grinding heads; the grinding heads and the feeding mechanisms are arranged in the box body; a blowing unit blows wind to the grinding device to blow up sparkles and dust generated by the grinding device when the rail is ground; an air draft unit sucks the sparkles and the dust into a dust filtration unit and filter and precipitate the dust in the dust filtration unit; and the filtered air is exhausted through the air outlet of the air draft unit. By virtue of the blowing unit and the air draft unit, the blowing unit generates powerful airflow to roll up most of the dust, change the motion track of the dust; the air draft unit generates powerful dust precipitating airflow to suck the rolled dust and the other particles into the dust filtration unit, and filter and precipitate the dust in the dust filtration unit, so that the dust control efficiency can be improved.

Description

technical field

[0001] The invention relates to mechanical manufacturing technology, in particular to a track grinding dust collection system and a grinding vehicle. Background technique

[0002] With the development of high-speed and heavy-duty railways, the use of rails is becoming more and more demanding. Rails will have defects such as fatigue cracks, fat edges, and wave wear, which will affect the stability and safety of railway vehicles. At the same time, the above defects will accelerate The failure of the rail will bring about a large economic loss. Preventive and remedial maintenance of rails is a necessary measure to prolong rail life, improve comfort, economy and safety. At present, rail repair methods mainly include grinding, planing, milling, and manual grinding. Among them, the use of efficient grinding vehicles to repair rails is the most common.

[0003] When the grinding car is working, the rail is ground by the high-speed rotating grinding wheel to remove...
