Rail joint vitreous enamel insulating spacer

Abstract

The invention relates to a key component of a rail insulation joint, which lies at the rail joint of two ends of a rail line block partition for dividing rail circuit segment and separating adjacent rail circuit belonging to the railroad rail circuit technique field. The invention provides an insulation pad which is provided with high strength and high friction between a rail cap and a clamp (or named as rail splice), wherein the pad uses stainless steel as base, two faces of the pad are baked with enamel which is sanded and roughens the surface to brush a layer of silicon rubber, the outline is the same as the inside surface of the rail joint, the aperture on the pad and aperture distance are the same as the aperture and aperture distance of the clamp. The goal of the key component of the high-strength rail insulation joint is simple in preparation, inexpensive in cost and convenient in assembly, which also satisfies high-load dynamic loading fatigue action.

Description

technical field [0001] The invention relates to a key part of a rail insulation joint, which is located at the rail joint at both ends of a blocked section of a railway line, and is used to divide sections of track circuits and separate adjacent track circuits, belonging to the technical field of railway track circuits. Background technique [0002] The rail insulation joints are located at the rail joints at both ends of the closed partition and are an important component of the track circuit. The function of rail insulation is to divide the sections of the track circuit and separate adjacent track circuits. Therefore, it is required not only to have good insulation performance, but also to have sufficient mechanical strength to make it crawl on the rail and withstand the impact of the wheels. It will not be damaged soon, so as to ensure the safety of train operation. [0003] At present, on the railway lines with track circuits, there are mainly two types of insulating jo...

AI Technical Summary

Problems solved by technology

[0003] At present, on the railway lines with track circuits, there are mainly two types of insulating joint structures used to connect rails: one is the ordinary insulating joint structure, which has the advantages of simple structure, convenient disassembly and assembly, and low price, but there are structural The shortcomings of low strength, small joint resistance, many joint diseases, and large maintenance workload. This kind of insulating joint is a prominent weak link on the line and affects the speed increase of the railway line; the other is the glued insulating joint structure, which has the overall It has the advantages of high strength, good insulation performance and less maintenance workload, but it has disadvantages such as inconvenient handling, troublesome construction, difficult to deal with faults and high price, and this kind of insulating joint structure cannot be used in some parts of the turnout area, so it is not conducive to crossing Development of interval seamless lines
