Force measurement wheel set calibration test stand

Abstract

A force measurement wheel set calibration test stand comprises a T-shaped stand base, portal systems and a transverse loading system. The force measurement wheel set calibration test stand is characterized in that perpendicular guide systems are installed on the portal systems and used for fixing a wheel set and achieving perpendicular loading; a bottom plate system is arranged at the position, below two portal top beams of the two portal systems, of the T-shaped stand base and used for adjusting track gauge, provides a platform for applying longitudinal force and transversely limiting the wheel set; a wheel set rotating indexing system is arranged at one end of the T-shaped stand base and used for achieving loading of any automatic rotating angle of the wheel set. According to the force measurement wheel set calibration test stand, perpendicular force and transverse force are independently loaded on the wheel set, and combined loading of loads in three directions can also be conducted on the wheel set; the force measurement wheel set calibration test stand has the wide track gauge calibration capacity, and meets the requirement for calibrating force measurement wheel sets of railway vehicles with the meter gauge, railway vehicles with the standard track gauge, railway vehicles with the wide gauge and other different railway vehicles; the force measurement wheel set calibration test stand has the capacity for adjusting lateral moving amount of wheel track contact points, and provides required perpendicular, transverse and longitudinal loads in a hydraulic loading mode.

AI Technical Summary

Problems solved by technology

There are 4 sets of longitudinal limit devices, one on each side of each mast. The height is adjusted by the lifting motor driving the steel wire and other devices. The longitudinal limit is manually adjusted, which is inconvenient to operate. The head needs to be pushed against the bearing or the axle box horizontally and vertically Central location, the operation process is cumbersome and the reliability is low

[0005] 2. The test bench does not have a wheel set rotation mechanism, and the wheel set rotation is achieved manually. This type of rotation is not accurate, and the rotation process is cumbersome, which has a great impact on the test results.

[0006] 3. The test bench cannot complete the automatic adjustment of the gauge, and the longitudinal position needs to be manually adjusted for wheelsets of different rails, so the automation rate is extremely low
