Description
Technical Field
The invention relates to a coupler height prediction device for a railway vehicle and a using method thereof.
Background
The coupler buffer device is an important component of the railway vehicle and directly relates to the performances of the railway vehicle, such as connection reliability, longitudinal dynamics and the like. Railway car coupler height refers to the distance between the coupler horizontal centerline and the upper surface of the rail. When the height difference of the two couplers connected with each other exceeds the allowable range, the reliability, the stability and the comfort of the train are affected, and the running safety of the vehicle is even endangered. The standard of China has strict requirements on the height, upwarp and sagging of the coupler of the railway vehicle, and the height of the coupler needs to be strictly controlled within the range of 880+/-10 mm. When the vehicle is manufactured, operated and overhauled, the height of the coupler is required to be adjusted so as to meet the requirements of standard and technical files, and the aim of safe operation of the vehicle is fulfilled.
The coupler height dimension is mainly affected by several factors: the steering frame center panel height, the outer deflection of the car body sleeper beam, the positioning size of the impact seat, the installation size of the coupler joist or the supporting seat and the installation size of the coupler yoke pin wearing plate. At present, the adjustment of the height of the coupler mainly meets the related requirements by changing the wear plates of the coupler support seat or the wear plates of the joist with different thicknesses to adjust the height of the coupler when the vehicle falls, and the height of the coupler can be measured only after the whole vehicle falls. If the tolerance requirement is not met, the detection of the whole vertical dimension chain is needed, the reason analysis and the repair are carried out, the repair process is complex and long, the normal production of the vehicle is affected, and the manufacturing cost is increased.
The chinese patent application of application number 200720140979.8 discloses a car coupler height gauge, it includes: and the PLC control device is connected with the displacement sensor and the data display screen. After the displacement sensor collects data from the center line of the coupler to be detected to the track plane, the PLC control device receives the data and calculates the height value from the center line of the coupler to the track plane, and the data display screen displays the calculated height value. The coupler height measuring instrument can only measure the coupler height after the whole car falls into, so that the problems are solved.
In view of the above, it is necessary to measure and control the relevant dimensions during the assembly of the chassis of the vehicle or the assembly and adjustment of the steel structure, and to determine in advance whether the height of the coupler assembled by the coupler buffer device meets the standard requirements, so as to avoid the repair due to repeated replacement of the wear plate of the coupler support seat and the out-of-tolerance height of the coupler.
