Railway freight safety door calibration device and railway freight safety door calibration vehicle

Abstract

The invention discloses a calibration device for railway freight safety doors, comprising a telescopic demarcation door, a servo system and a transmission mechanism, wherein the outer surface of the telescopic demarcation door comprises a standard demarcation surface, a first-level demarcation surface and a second-level demarcation surface; the shapes and sizes of the standard demarcation surface, the first-level demarcation surface and the second-level demarcation surface under working condition are respectively identical to the shapes and sizes of standard demarcation, first-level demarcation and second-level demarcation; the servo system comprises a driving motor and is used to control the demarcation door to expand and contract; the transmission mechanism has an output end connected with the demarcation door, and has an input end connected with an output shaft of the driving motor, so as to convert the rotating motion output by the driving motor into the linear motion of the demarcation door. The calibration device for railway freight safety doors can simultaneously carry out the calibration of standard demarcation, first-level demarcation and second-level demarcation to safety doors, and has high calibration precision. On the basis of the calibration device, the invention also discloses a calibration vehicle for railway freight safety doors, which does not need field installation or debugging, and can save calibration time and improve calibration efficiency.

Description

technical field [0001] The invention relates to the field of measurement of irregular surfaces or contours, in particular to a railway freight safety door calibration device and a railway freight safety door calibration vehicle. Background technique [0002] With the development of economic construction, the long and large cargo transported by railway is increasing. According to the requirements for the safety of freight train operation, the freight vehicles and the goods loaded therein must not exceed the specified outline dimension line, that is, the railway limit; otherwise, the freight vehicles and the goods loaded on them may hit the buildings adjacent to the line or equipment, and thus cause a safety incident. For this reason, it is necessary to detect the outline of the running trucks and vehicles and their loaded goods in real time, and give an alarm immediately when it is detected to exceed the limit, so as to prevent it from hitting buildings or equipment adjacent...
