Embodiment

[0035] Please refer to figure 1 and figure 2 , a rail corrugation detection device, comprising: a long box 10. Both ends of the top of the box body 10 are respectively provided with moving handles 15 for moving the rail corrugation detection device on the rail 40 , so that the rail 40 can be continuously detected. A portable handle is provided at the middle position on the top of the box body 10, which is convenient for carrying the rail corrugation detection device. The bottom of the box body 10 is provided with an opening, and the extension direction of the opening is consistent with the extension direction of the box body 10 , and the two ends of the bottom of the box body 10 are respectively provided with bases 11 .

[0036] Please refer to image 3 The inside of the box body 10 is provided with a detection assembly 20 and two unlocking assemblies 30, and the two unlocking assemblies 30 are respectively arranged at both ends of the box body 10 and connected to the base...

Abstract

The invention discloses a steel rail corrugation detection device and belongs to the technical field of rail detection. The steel rail corrugation detection device comprises a box body with an openingin the bottom and a detection assembly located in the box body, wherein the detection assembly comprises a servo electric cylinder, a connecting block and a 1D sensor, the servo electric cylinder isarranged at the top of an inner side of the box body in the extending direction of the box body, the connecting block is slidably connected with the bottom of the servo electric cylinder and the top of the 1D sensor, the sliding direction between the connecting block and the servo electric cylinder is perpendicular to the sliding direction between the connecting block and the 1D sensor, and a detection port of the 1D sensor penetrates through the bottom opening of the box body. The steel rail corrugation detection device is advantaged in that the steel rail corrugation detection device can drive the 1D sensor to be linked in the transverse direction and the longitudinal direction so that three-dimensional detection of the shape of a top surface of a rail can be realized, the detection range is large, judgment of a rail state is complete, and misjudgment of rail damage is avoided.

Description

technical field [0001] The invention relates to the technical field of rail detection, in particular to a rail corrugation detection device. Background technique [0002] The rail directly bears the mass and impact from the wheel set, and the surface will be damaged. Some lines will form corrugation phenomenon under periodic wear and tear. The car body will generate relatively vibration and noise when it is running. Long-term track wear will increase the amount of track displacement and deteriorate the track state, leading to intensified track wear, section cracking, block falling and other defects. In severe cases, the risk of derailment and overturning will be aggravated. In order to prevent the occurrence of such vicious events, it is necessary to carry out effective measurement and diagnostic analysis on rail corrugation. [0003] There are mainly two types of portable testing equipment for rail corrugation: contact and non-contact. The contact measuring device uses th...
