Description
Technical Field
The utility model relates to a track locomotive control valve test technical field specifically is a device for detecting track locomotive control valve blind spot angle.
Background
In the process of running of a rail vehicle or getting on and off passengers, the change of the load of the vehicle can cause the change of the height of a vehicle body relative to a rail surface, in order to keep the vehicle body at a certain height, when the load of the vehicle body changes, air is filled into or exhausted from an air spring of the locomotive through a control valve, the load distribution can slightly change due to the uneven line of the locomotive in the running process or the continuous walking of personnel on the locomotive and other reasons, if the slight change can cause the work of the control valve, the working frequency of the control valve can be increased, the service life of the control valve is greatly shortened, therefore, according to the actual use requirement and the research and study of professional technicians, a dead zone angle is provided in the performance of the control valve, namely, the control valve does not carry out air filling and exhausting work under the slight load change of the locomotive, and the size of the dead zone has great influence on the control valve, the dead zone angle is too large, so that obvious fluctuation is caused, the stability of the locomotive and the comfort of passengers are influenced, and the dead zone angle is too small, so that the working frequency of the control valve is increased, and the service life of the control valve is further influenced; therefore, the dead zone angle detection is important after the control valve is assembled.
At present, the dead zone angle after the control valve is assembled is mainly tested by adopting an automatic detection method controlled by a servo motor, and the test method has the disadvantages of higher cost, more complex operation and fussy detection work.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a device for detecting track locomotive control valve blind spot angle solves the problem of proposing among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a device for detecting track locomotive control valve dead zone angle, includes the support frame, from the goniometer, link and the control valve of taking fine-tuning, the goniometer is fixed in on one side of support frame, the control valve is fixed in on the opposite side of support frame, just the axis of the pivot of control valve is located same axis with the central point of goniometer, the one end of link is fixed in on the goniometer, the other end and the pivot fixed connection of control valve, be provided with the rotatory handle of angle scale on the goniometer.
Preferably, the cross section of the support frame is of a U-shaped structure.
Preferably, the support frame is provided with an angle instrument mounting hole and a control valve mounting hole, and the angle instrument and the control valve are respectively connected in the angle instrument mounting hole and the control valve mounting hole through bolts.
Preferably, the link includes the U-shaped body, is provided with the mounting groove on the lateral wall of U-shaped body, the pivot joint of control valve in the mounting groove, rethread fixing bolt is fixed.
During operation, to wait to examine the pivot of examining the control valve and put into the mounting groove of link, pass the connecting hole of examining the control valve with fixing bolt, fix the control valve on the support frame, then tighten fixing bolt on the link, the control valve will be connected with link and angle appearance completely this moment, after connecting the test pipeline, through the handle and the fine motion knob of turned angle appearance, just can accurately measure the blind spot angle of control valve.
