Example Embodiment

[0015] The present invention will be further described below in conjunction with the drawings:

[0016] figure 1 It is a schematic diagram of the installation of the train wheel set detection system of the present invention. The train wheelset detection system mainly consists of sensors (8), conditioners, data collectors, data processing and analysis software, etc. After the train enters the fault diagnosis and rehabilitation center, it is installed on the axle box, bogie (4), gear Acceleration of the box (seat) (7), motor housing, anti-snake shock absorber and other parts of the laser wheel profile measuring instrument (3) fastened to the positioning arm to detect the status parameters of the wheel set and frame to complete the train The characteristics of wheelset (5) bearing (2) state, bogie (4) stability, imbalance and resonance state are extracted, and these state characteristic parameters are sent to the fault diagnosis and rehabilitation center of the base via wireless net...

Abstract

A fault diagnosis and rehabilitation center for train wheel sets comprises a train wheel set state detection device, a laser tread outline measuring device and a fault diagnosis and rehabilitation center, wherein the train wheel set state detection device mainly comprises a vibration sensor, a conditioner, a data collector, data processing and analyzing software and the like, completes characteristic extraction of the state of train wheel set bearings, and the stability, the unbalance and the resonance state of a steering frame through train wheel set state detection and sends the state characteristic parameters to the fault diagnosis and rehabilitation center of a base through a wireless network; the laser tread outline measuring device utilizes a mature and advanced laser wheel set tread outline instrument to measure the outline state of the wheel sets, promptly forecasts the characteristic parameters, such as abrasion, flat damage, stripping, outline shapes and the like of the wheel sets, and sends converted data signals to the fault diagnosis and rehabilitation center of the base through the wireless network; and the failure diagnosis and rehabilitation center can real-timely analyze the running state of the wheel sets, promptly warn possible faults, intelligently compile a repair and numerically-controlled processing scheme for the wheel sets, transmit the scheme to a non-pulling wheel numerical control machine tool and intelligently process the outlines of the warehoused wheel sets.

Description

technical field [0001] The invention relates to the fields of machinery, instruments, and measurement and control, and in particular to a design scheme for a train wheel set diagnosis and rehabilitation center such as train wheel set state detection, fault diagnosis, and non-drop wheel turning repair technology. Background technique [0002] Due to the strict restriction of economic factors, the service life of locomotive structural components (including train wheel sets) is a very important issue for manufacturing enterprises and railway departments. As one of the important components of the rolling stock running mechanism, the high-speed wheel set has a direct impact on the safety and reliability of the rolling stock operation. During the long-term service of the train, due to the differences in the wheel set material, line conditions, traction conditions, weather conditions, lubrication conditions and other factors, the wheelset often has defects such as scratches, flat s...
