Abstract

The invention discloses a rail vehicle wheel cake parameter measuring device and a data processing method, the rail vehicle wheel cake parameter measuring device comprises a machine body, wherein themachine body is internally provided with a high-precision sliding rail module, a driving rack, a main control unit, a data storage and interaction unit and a power supply unit, a magnet adsorption anddisengagement device is arranged outside the machine body, the magnet adsorption and disengagement device is provided with a mark block used for determining the transverse position of the inner sideend face of a wheel cake and a rolling circle diameter measuring cushion block which is provided with a magnet and is adsorbed on the edge of the inner groove of the measured wheel cake, a laser emitter and a stay wire type displacement sensor are arranged at the rear part of the machine body, and the main control unit is connected with a handheld mobile terminal. Compared with a traditional manual measurement mode, the measuring precision and the measuring efficiency of the rail vehicle wheel cake parameter measuring device are improved, and the service life of the wheel cake of a railway vehicle is prolonged.

Description

technical field [0001] The invention relates to the technical field of rail vehicle wheel set maintenance, in particular to a rail vehicle wheel cake parameter measuring device and a data processing method. Background technique [0002] The various functions of the current wheel set maintenance equipment are separated from each other and completed by different equipment, systems or operators. The current train wheel set size detection mainly has the following problems: the traditional detection ruler has low measurement efficiency and cannot realize the measurement of the tread profile, and it is manually read and recorded, and the measurement error is greatly affected by human factors. [0003] Therefore, it is necessary to invent a rail vehicle wheel cake parameter measuring device and a data processing method to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a rail vehicle wheel cake parameter measuring de...
