Problems solved by technology

Previously, the measuring instruments used to detect the shape of the wheel rim treads of the above four types of motor vehicles were still used for the inspection of wheel rims of ordinary rolling stock. Measuring instruments for rolling wheel rim detection cannot meet the requirements. Since the measurement benchmark is different from that of ordinary locomotives, the measurement results need to be converted, and the QR value cannot be measured. (QR value is an important measurement parameter for the wheel measurement of EMUs

Abstract

The invention relates to a motor train unit checker. The motor train unit checker comprises a ruler body 12, a flange height and tread abrasion measuring ruler frame 4, a flange height and tread abrasion measuring ruler face 2, a QR value main ruler 7, a QR value vernier 6, a rim width measuring ruler 8, a flange thickness measuring ruler 9, a rim width measuring ruler frame 11, locating angle iron 15, and locating pin handle 19, wherein the ruler body 12 is integrally configured by two straight rulers vertical to each other, the rim width measuring ruler frame 11 slidably sleeves a horizontal ruler of the ruler body 12, the flange height and tread abrasion measuring ruler 4 is vertically fixed at the side of the horizontal ruler of the ruler body 12, the flange height and tread abrasion measuring ruler face 2 is slidably mounted inside the flange height and tread abrasion measuring ruler frame 4, the flange thickness measuring ruler 9 is integral with the QR value main ruler 7 and can slide inside a ruler frame under the rim width measuring ruler frame 11, and the QR value vernier 6 is fixed on the ruler body 12. The motor train unit checker can be used for wheel flange and tread appearance check, and has the characteristics of direct reading, definite locating, and good repeatability.

Description

technical field [0001] The invention relates to a motor train unit inspector, which is a special tool for inspecting the shape of the wheel flange tread surface of a railway motor car, and belongs to the field of wheel shape detection. Background technique [0002] In recent years, my country's railway industry has developed rapidly, especially the development of high-speed rail is in a leading position in the world, and it has quickly followed up in the manufacturing and testing of bullet train wheels. However, the development of special measuring instruments for the shape inspection of wheel flange treads of CRH1, CRH2, CRH3 and CRH4 four kinds of EMUs has been slow. Previously, the measuring instruments used to detect the shape of the wheel rim treads of the above four types of motor vehicles were still used for the inspection of wheel rims of ordinary rolling stock. Measuring instruments for rolling wheel rim detection cannot meet the requirements. Since the measurement...
