Rail fat edge detection device

Abstract

The invention discloses a rail fat edge detection device, which comprises a rail roller and a splint. The rail roller can roll along the rail surface, and the width of the rail roller is the same as the width of the rail surface without the fat edge. Consistently, the upper end surface of the rail roller is provided with a connecting rod; the splint is used to clamp the two sides of the rail roller and the two sides of the rail, the splint is connected to the connecting rod through a spring, and the splint passes through The spring can be stretched when clamping the fat edge rail; it also includes a marker box arranged on the upper end surface of the rail roller for storing marking media, the opening of the marker box is set downwards, and the opening faces the splint Corresponding to the clamping seams on both sides of the rail roller; the opening is sealed by a sealing plate connected to the splint, which can be removed when the splint is stretched and no longer fully sealed Keep your mouth shut. It can detect the fat edge of the rail surface and mark the fat edge for grinding, and the detection result is intuitive 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
