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...

The invention discloses a calibration device for a railway freight safety door, which includes a retractable boundary door, the outer surface of which includes a standard boundary, a first-level boundary and a second-level boundary, the standard boundary, the first-level boundary and the second-level boundary The shape and size of the limit surface in working conditions are the same as those of the standard limit, the first level limit and the second level limit respectively; the servo system, including the drive motor, is used to control the expansion and contraction of the limit door; the transmission mechanism, its output The end is connected with the limit door, and its input end is connected with the output shaft of the driving motor, which is used to transform the rotary motion output by the drive motor into the linear motion of the limit door. The railway freight safety door calibration device can simultaneously calibrate the standard limit, the first-level limit and the second-level limit for the safety door, and the calibration accuracy is high. On this basis, the invention also discloses a railway freight safety door calibration vehicle, which does not require on-site installation and debugging, 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...
