Device for collecting steel rail parameters

The invention relates to the field of steel rail detection, in particular to a device for acquiring steel rail parameters, which comprises a fixed bracket, a contour acquisition mechanism and an image acquisition mechanism, the fixing support is provided with a channel for a steel rail to penetrate through. The contour acquisition mechanism and the image acquisition mechanism are both installed on the fixed support and are both aligned with the channel. A steel rail penetrates through the fixing support, the contour collecting mechanism collects contour information of the steel rail, such as the type size, straightness and torsion resistance of the steel rail, the image collecting mechanism collects surface image information of the steel rail, and then the collected information is concentrated in an information analysis/comparison system such as manual work or a computer to be analyzed/compared. Therefore, whether the type size, the straightness, the torsion resistance and the surface quality ...
