Abstract

The invention discloses a fast measuring device and a measuring method for the body length of an EMU. The measuring device includes a frame, an inverted V-shaped plate is arranged on one side of the frame, and a base of a servo electric cylinder is installed at the end of the inverted V-shaped plate. The upper end of the frame is hinged with the three-link mechanism, and the output end of the servo electric cylinder is hinged with the three-link mechanism; the end of the three-link mechanism is provided with a pedal-type pressure sensor, and the end of the pedal-type pressure sensor is connected to the pressure plate through a universal joint ball bearing. Hinged, the pressure plate is respectively provided with an inclination sensor and an infrared distance sensor; the measurement method includes installing the measuring device on the columns on both sides of the car body, and attaching the pressure plate to the front and rear end surfaces of the car body. The invention can solve the problem in the prior art that there is no method for accurately measuring the length of the car body of the EMU, and has high detection precision, strong 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...
