Abstract

The invention discloses a non-falling wheel-type wheelset multi-stage out-of-roundness measurement system comprising an image acquisition device for acquiring a contour curve of a wheel tread, a top runner mechanism for lifting the wheel and driving the wheel to rotate, and a mobile platform for carrying and transferring the image acquisition device and the top runner mechanism, wherein the imageacquisition device comprises a camera and a linear light source; the top runner mechanism comprises a swing arm for lifting the wheel and a runner for driving the wheel to rotate; the mobile platformcomprises a vehicle body, a walking wheel is arranged below the vehicle body, and the vehicle body contains a controller; and a processing computer for analyzing the images acquired by the image acquisition device and outputting a calculation result of out-of-roundness is provided. The wheelset out-of-roundness is measured on-line to avoid the heavy work of disassembling the wheelset. The compactdesign allows free access to the maintenance trench. The mobile measuring mechanism can cover all wheelsets in the parking lot.

Description

technical field [0001] The invention relates to a system for measuring the out-of-roundness of a train wheel set, in particular to a system for measuring the out-of-roundness of a train wheel set without dropping wheels. Background technique [0002] After the train runs for a period of time, the tread of the wheel will wear unevenly. When the wear reaches a certain value, the out-of-roundness of the wheel will cause additional vibration, impact, and noise to the vehicle, which will affect the stability of the vehicle and cause serious damage to the safety of the train. threaten. Therefore, the out-of-roundness of the wheel should be checked regularly. [0003] The detection methods of the out-of-roundness of train wheels are mainly divided into static detection and dynamic detection. According to the detection principle, the current main dynamic detection methods can be divided into: "vibration acceleration monitoring method", "contact measurement method", "displacement m...
