A device for repairing wheel treads using additive materials

Abstract

The invention discloses a device for repairing wheel treads by using additive materials, which relates to the technical field of wheel repair of EMUs, including: slide rails, racks, boxes, supporting devices, driving devices, wheel heating devices, ingot heating devices and stirring Output device; the slide rail is fixed on the ground, the frame is set above the slide rail, the upper end of the box is fixedly connected to the frame, the supporting device and the driving device are both slidably connected to the slide rail, and the output end of the driving device is fixedly connected to the wheel , the lower part of the box is provided with a semicircular notch, the wheels are located below the semicircular notch, and the wheels are arranged eccentrically relative to the semicircular notch; the wheel heating device is fixedly arranged under the box body, and the ingot heating device and the stirring output device are fixedly arranged in the box body, The ingot is heated, and the ingot heating device is connected with the stirring output device to overcome the defect that the existing repair method causes the wheel to become smaller. Using additive materials to repair the wheel tread is conducive to saving materials, and the repair process saves time and effort.

Description

technical field [0001] The invention relates to the technical field of motor train wheel repair, in particular to a device for repairing wheel treads by using additive materials. Background technique [0002] With the large-scale high-speed operation of EMUs in my country, the problem of wheel wear has become increasingly prominent. High-speed train wheels are subjected to large fluctuations in load during high-speed operation, which is very easy to cause tread damage. After the wheel treads of high-speed trains are worn out, the dynamic performance will also decrease to varying degrees, which will affect the safe operation of the train. In order to improve the safety and comfort of train operation, it is very necessary to repair the wheel tread wear in time. At present, the treatment methods of wheel wear damage in various countries generally adopt regular wheel set repairing, rail grinding and other methods to restore the wheel set to the reference profile to improve the ...
