Embodiment Construction

[0031] For the convenience of describing the present invention, relevant terms are explained as follows:

[0032] Railway limit: In order to ensure the safety of rolling stock running on the railway line and prevent rolling stock from colliding with buildings and equipment adjacent to the line, the contour dimension line that is not allowed to exceed the rolling stock and buildings and equipment adjacent to the line, Called the Rail Gauge. The overall dimensions of the railway rolling stock shall not exceed the standard rolling stock limit; at the same time, after the goods are loaded, the height and width of any part of the goods shall not exceed the rolling stock limit (hereinafter referred to as the standard limit). If the height and / or width of any part of the cargo exceeds the standard rolling stock gauge, it is called over-gauge cargo. According to the degree of cargo overrun, it is divided into first-level over-gauge limit and second-level over-gauge limit (hereinafter...

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...
