The invention discloses a milling detection device, which comprises a transverse detection mechanism arranged on the lower surface of a spindle box, and two vertical detection mechanisms. The transverse detection mechanism is arranged between the two vertical detection mechanisms. The three detection mechanisms are arranged along the length direction of a steel rail. The transverse detection mechanism comprises a transverse installation frame arranged on the spindle box, and a profiling finger support arranged on the back surface of the transverse installation frame and capable of sliding along the transverse direction. The bottom end of the profiling finger support is provided with a profiling finger configured to abut against the side surface of the steel rail. The device further comprises a transverse length meter used for detecting the transverse sliding displacement of the profiling finger. Each vertical detection mechanism comprises a vertical installation frame arranged on the spindle box, and a pressing plate support arranged on the back surface of the vertical installation frame and capable of sliding along the vertical direction. The bottom end of the pressing plate support is provided with a pressing plate configured to be in contact with the upper surface of the steel rail. The device further comprises a vertical length meter used for detecting the vertical sliding displacement of the pressing plate. By means of the above milling detection device, the positioning and the feeding of a milling cutter disc and the steel rail can be realized quickly and accurately.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, and more specifically, to a milling detection device. Background technique [0002] With the rapid development of rail transportation, railways, light rails, and subways are more and more widely used, high-speed and heavy-duty operations are put into operation, and the traffic volume is increasing. The use of rails is becoming more and more demanding. Damage, such as scratches or spalling of the rail surface, cracks on the side of the rail, and wavy wear, etc., have affected the railway transportation capacity and economic benefits. In order to improve the service life of the rails and ensure the safety and comfort of driving, the rails must be maintained regularly to prevent damage and further deterioration. [0003] At present, the commonly used rail maintenance equipment includes rail grinding car and rail milling car. The rail milling car with the advantages of environmental friendline...
