A bogie detection device

Abstract

The invention discloses a bogie detection device. The device comprises a supporting frame, a bearing device, a measurement arm, a conveying aiding frame, a moving trolley and a buffer, wherein the moving trolley is movably arranged on the conveying aiding frame; the buffer is mounted on the inner side of a sliding rail of the conveying aiding frame and is provided with a casing, a blocking shaft, a drive plate and an annular piston, the annular piston is movably arranged in an annular cavity of the casing, the drive plate is located in a front hole of the casing, and the blocking shaft is connected at the front end of the drive plate, penetrates out of an end cap of the casing and is in sliding fit with the end cap; the blocking shaft is contacted with the left end of the moving trolley at the moment when the moving trolley moves to the left end of the conveying aiding frame and stops, the moving trolley pushes the blocking shaft to move, so that the drive plate is contacted with the annular piston and drives the annular piston to compress air in the annular cavity, and then, the moving trolley is stopped slowly. The bogie feeding process is simple, quick and stable.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a bogie detection device. Background technique [0002] In the prior art, the main dimensions such as the gap between the frame and the wheels of the bogie of the EMU, and the diagonal are manually measured and recorded by a special measuring ruler and a marking tool. When performing manual measurement, the measurement position of the bogie needs to be determined visually and by marking, resulting in deviations in measurement accuracy, and repeated measurement and adjustment are required during the operation, which is labor-intensive. At present, there is also an automatic detection device. The bogie is transferred to the predetermined position of the detection device through the conveying device, locked and fixed, and then measured. When the sensor is used to control the conveying device to the predetermined time, overshoot often occurs. If the limit block is used dire...

When performing manual measurement, the measurement position of the bogie needs to be determined visually and by marking, resulting in deviations in measurement accuracy, and repeated measurement and adjustment are required during the operation, which is labor-intensive

At present, there is also an automatic detection device. The bogie is transferred to the predetermined position of the detection device through the conveying device, locked and fixed, and then measured. When the sensor is used to control the conveying device to the predetermined time, overshoot often occurs. If the limit block is used directly, it will appear Strong impact, even rebound phenomenon
