The underground ore rubble transportation is mostly rail transportation, i.e. a plurality of mine cars are dragged to travel to a destination on a preset rail by an electric locomotive head. The rail-bound transportation has the advantages of suitability for long-distance transportation and large transportation amount in single trip. The requirement of rail-bound transportation on wheels of electric locomotives and mine cars is very high, and if the wheels of a certain mine car filled with ore cannot rotate flexibly in the transportation process, the situation of falling off the road is likely to occur. When the rail is found to be out of the way, the rail is possibly damaged untimely and cannot pass normally, or the rail is not on the way in time, so that transportation blockage is caused, the normal running of underground production is delayed, and huge economic loss is caused.
Inspection, maintenance and repair of mine car wheels is very important in everyday work and they are replaced immediately once a problem is found. The damage rate of the mine car wheels is high due to the heavy transportation tasks. A mine car usually has four mine wheels, which are divided into a front group and a rear group, every two mine wheels are connected into a group through a shaft, and each group of mine wheels and the middle wheel shaft are called wheel pairs.
The maintenance of the mine car wheels generally has two conditions, namely that finished wheel sets are manufactured to plan to directly replace the wheel sets, and the mine car wheels of the wheel sets are disassembled to replace bearings and then are reassembled. The first method is too high in cost, one finished wheel pair is 500 yuan, 80 wheel pairs are replaced every month, and the cost is 40000 yuan. The second method is low in cost, only 100 yuan is needed for replacing the bearings of one set of wheel pairs, but the difficulty of replacing the bearings is to disassemble the wheel pairs. Because the shaft of the wheel pair is firmly connected with the wheel, the prior method uses a hammer to beat, which is not safe and has low efficiency, and three people can only repair 6 wheel pairs each day, thus completely meeting the production requirement.
