Description
Technical Field
The invention relates to a testing instrument, in particular to a horizontal table detection device of a wheel load reduction multifunctional test bed.
Background
The wheel load reduction multifunctional test bed is mainly used for testing wheel load detection, flexibility coefficient and wheel load reduction rate of the railway vehicle. Because the test stand can satisfy the changes of the track gauge and the wheel base of the railway vehicle, the change can cause that the weighing platform can not be in the same horizontal plane to cause the deviation of wheel weight measurement. Since the height difference of the weighing platform can affect the weight distribution of the wheels of the railway vehicle, in the conventional use, the experimenter needs to detect the levelness after each adjustment so as to ensure the reliability of the measuring result. The influence of the difference in weight on the test apparatus itself in weighing was not confirmed.
The levelness of each supporting point needs to be adjusted before a rail vehicle weighing test is carried out in the prior work, particularly for a test bed which often needs to change track gauges and wheel bases in a laboratory, when the levelness of the test bed is adjusted in a wide range on a horizontal plane linear track (meeting the requirements of wheel weight measurement of rail vehicles with different track gauges and wheel bases), the levelness of the test bed needs to be monitored to meet the precision requirement of 0.8mm specified by a standard. In the conventional mode, the theodolite/laser tracker is used for measurement, the theodolite belongs to a relatively precise instrument, and can be conveniently adjusted by a vertical adjusting mechanism of the test bed supporting device after being detected to be out of level. However, when a vehicle is on the platform, the change in levelness due to the deformation of the floating platform under different vertical loads is not known.
