Fat edge detection device for rail

Abstract

The invention discloses a fat edge detection device for a rail. The fat edge detection device comprises a rail rolling disc, clamp plates and marker boxes. The rail rolling disc can roll along a rail surface, the width of the rail rolling disc is equal to that of the rail surface without fat edges, and a connecting rod is arranged on the upper end face of the rail rolling disc. The clamp plates are used for clamping two side edges of the rail rolling disc and two side edges of the rail, are connected with the connecting rod through springs and can be expanded through the springs when clamping the rail with fat edges. The marker boxes are arranged on the upper end face of the rail rolling disc and used for storing marking substances, an opening of each marker box faces downwards, and orientations of the openings correspond to clamping seams of the clamp plates and the two side edges of the rail rolling disc. Each opening is sealed through a seal plate which is connected with the corresponding clamp plate, and the seal plates can be removed to no longer completely seal the openings when the clamp plates are expanded. The fat edges are marked to facilitate grinding while the rail surface is subjected to fat edge detection, and detection results are visual and accurate.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for rail fat edge. Background technique [0002] Due to the long-term and repeated rolling and impact of the train wheels on the rails, there will be larger and larger fat edges on the edge of the rail surface; if the normal gauge is changed by the larger and larger fat edges, The safety of the train will be seriously affected. Therefore, the rails need to be inspected frequently, and when the fat edge is found to be too large, the fat edge should be removed in time, usually by a grinder. [0003] In the prior art, vernier calipers are generally used to detect whether the rail fat edge meets the operating range, but such a detection method is time-consuming and laborious, and the efficiency is low; there is also a method of using automatic detection instruments, although the efficiency is improved, but the operating cost of the equipment Extremely high, and there is a ce...

Problems solved by technology

[0003] In the prior art, a vernier caliper is generally used to detect whether the fat edge of the rail meets the operating range, but this detection method is time-consuming and laborious, and the efficiency is low; there is also a method of using an automatic detection instrument, although the efficiency is improved, but the operating cost of the equipment Extremely high, and there is a certain bias in the detection data, and there is a phenomenon of missed detection

In addition, after using the detection methods in the prior art to detect the rails, there is no convenient and flexible equipment for marking the rail surface with too large fat edge for easy grinding
