Portable railway wheel tread parameter detection instrument

Abstract

The invention discloses a portable railway wheel tread parameter detection instrument. The portable railway wheel tread parameter detection instrument consists of a base, a cover, a flange tread measuring mechanism, a rim thickness measuring device, a positioning device, a control device, a touch screen and a USB (Universal Serial Bus) interface, wherein the flange tread measuring mechanism comprises a laser sensor and a horizontal moving mechanism; the rim thickness measuring device comprises a positioning mechanism, a measuring head, an electronic ruler and a manual vertical moving guide rail pair; the flange tread measuring mechanism, the rim thickness measuring device and the positioning device are fixedly arranged on the base. The portable railway wheel tread parameter detection instrument is used for detecting the parameters of a railway wheel such as flange thickness, flange height, tread abrasion, rim thickness, rim width, vertical flange abrasion, QR value and tread scratch depth. Laser measurement and the touch screen are adopted, thereby achieving the characteristics of storability of measured data, high accuracy, light weight, convenience in operating and carrying and storability of output data. The portable railway wheel tread parameter detection instrument is suitable for detecting tread parameters under the condition of not lowering down the wheel in plants, workshops, train examination, repair track maintenance, motor car stations, urban subways and the like.

Description

Technical field: [0001] The invention relates to a portable railway wheel tread parameter detector, which belongs to the field of railway wheel detection tools. Background technique: [0002] The wheel checker usually used in testing the wheel tread is used for railway wheel rim thickness, rim height, tread wear, rim thickness, rim width, rim vertical wear, QR value, tread scratch depth, etc. Parameter detection; it is a special measuring instrument that uses vernier readings, the measured data cannot be saved, the measurement stability is poor, the measurement speed is slow, and the measurement accuracy is low. Used wheel checker volume is big in addition, and weight is heavy, and it is inconvenient to carry. Invention content: [0003] The portable railway wheel tread parameter detector of the present invention is hereinafter referred to as "detector" for detecting railway wheel rim thickness, rim height, tread wear, rim thickness, rim width, rim vertical wear, QR v...
