Abstract

The invention discloses a rapid measuring device for a train body length of a D-series high-speed train and a measuring method thereof. The measuring device comprises a frame. An inverted V-shaped plate is arranged at one side of the frame; and a base of a servo electric cylinder is installed at the tail end of the inverted V-shaped plate. The upper end of the frame is hinged to a three-link mechanism; and the output end of the servo electric cylinder is hinged to the three-link mechanism. A pedal type pressure sensor is arranged at the tail end of the three-link mechanism; the end portion ofthe pedal type pressure sensor is hinged to a pressing plate by a universal joint ball bearing; and an inclination sensor and an infrared ranging sensor are arranged on the pressing plate respectively. In addition, the measuring method includes: installing the measuring devices at standing columns at the two sides of a train body; and enabling pressing plates to be in contact with the front end and the rear end of the train body. Therefore, a problem of being lack of the accurate measurement of the length of the D-series high-speed train body in the prior art is solved. The measuring device and measuring method have advantages of high detection precision, high adjustability, and fast detection speed.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a fast measuring device and a measuring method for the body length of an EMU. Background technique [0002] As one of the most critical components in the EMU, the car body of the EMU directly affects the appearance of the EMU car body and the installation accuracy of the bottom panel. At the same time, the size of the car body will also affect the size of its internal structure. In the process of EMU testing, it is necessary to measure the length of the car body for different cross-sectional angles of the EMU, so as to ensure the accuracy of the car body length of the EMU. [0003] The traditional measurement method requires workers to directly enter the pedestrian frame and use the measurement method of pulling tape at both ends to measure, which requires a lot of man-hours, considering the interference of other external factors, and the artificial repeated measurement acc...
