Embodiment Construction

[0043] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0044] The measuring device is composed of a wheel sensor 1 installed on the outside of the rail and measuring boxes 4 and 5 installed on the inside of the rail. The measuring box is arranged one on each of the left and right rails, and is respectively used for measuring the diameter of the left and right wheel sets. At the same time, two left and right rail position marking strips 3, 6 are arranged on the top of the measuring box.

[0045] Two digital cameras 8,9 are installed in the wheel set diameter measurement boxes 4,5; and two line laser generators 7,10. Wherein, the digital camera 8 and the line laser generator 10 constitute a rim thickness measurement assembly. The digital camera 9 and the line laser generator 7 constitute a rim inner circle diameter measuring assembly.

[0046] See figure 2 , image 3 , Figure 4 . The laser p...

Abstract

The invention relates to dynamic measurement of wheel diameters of railway vehicles such as wagons, passenger trains, bullet trains and locomotives in the normal running state on a railway. A device comprises a left wheel pair diameter size measuring box (4), a right wheel pair diameter size measuring box (5), a left steel rail position mark strip (3), a right steel rail position mark strip (6) and at least one wheel sensor (1). The wheel sensors (1) are connected with a digital camera (8), a digital camera (9), a line laser generator (7) and a line laser generator (10) through electrical signals. After detecting that wheels enter the detecting area, the wheel sensors (1) send signals to trigger the digital cameras and the line laser generators to work and then calculate the wheel diameters of the vehicle according to taken photos. By means of the device and method, railway wheel diameters can be accurately and dynamically measured.

Description

technical field [0001] The invention relates to a dynamic measurement device and method for wheel diameters of railway vehicles including freight cars, passenger cars, motor cars, locomotives and the like under normal running state on the railway. Background technique [0002] During the operation of railway vehicles, wear between the wheel and rail occurs. When the wheel wear is serious, it will affect the safety of the train. At present, various types of ground-to-vehicle dynamic detection systems are installed on railway lines or vehicle entrances at home and abroad. In this type of system, the dynamic measurement of wheel diameter is widely proposed as an item to be measured, and there are many technical solutions that have been realized and completed. [0003] Among them, the more representative ones are the three-point measurement scheme and the indirect measurement scheme of the wheel thickness. [0004] The three-point measurement scheme of the wheel diameter is to...
