Embodiment

[0037] 1. The structure of the seamless rail insulation safety device

[0038] Such as figure 1 and figure 2A seamless rail insulation safety device is shown, which is used at joints of seamless rails welded on site. The center is aligned with the rail weld 3, and the surface of the rail insulating splint 2 is attached with an insulating material; the bonding surface of the rail insulating splint 2 and the rail 1 is bonded with an insulating layer 4, and the center of the bonding surface An arc surface 5 of R40mm and depth of 30mm is processed at the place, and an insulating layer 4 is bonded there; The thickness is 30mm larger than that of the left and right parts; the overall length of the rail insulation splint 2 is increased by 103mm; the raw material of the rail insulation splint 2 is 40Cr steel; the two rail insulation splints 2 are fixed by 6 bolts Together, an insulating sleeve 7 is provided in the mounting hole of the bolt.

[0039] In this embodiment, the left a...

Abstract

The invention discloses a seamless steel rail insulation safety device, and belongs to the technical field of railway transportation. The device comprises two steel rail insulation clamping plates which are arranged at the two sides of two steel rail joints respectively, insulation layers are bonded to the fitting faces of the steel rail insulation clamping plates and a steel rail, arc hook faceswith the radius of 40 mm and the depth of 30 mm are machined in the centers of the fitting faces, and an insulation layer is also attached to each arc hook face; the middle of the surface of the outerside of each steel rail insulation clamping plate protrudes out for 30 mm; the overall length of each steel rail insulation clamping plate is increased by 103 mm; the raw material of the steel rail insulating clamping plates is 40Cr steel; the two steel rail insulating clamping plates are fixed together through a bolt, and an insulating bush is arranged in a mounting hole of the bolt. The devicehas a good reinforcing effect and good insulating performance and is convenient to install; during installation, steel rail welding parts do not need to be completely ground, and the strength of steelrail welding seams and the device cannot be influenced either.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a seamless rail insulation safety device. Background technique [0002] my country's railway (high-speed rail or main line railway) track is a seamless line, which is formed at the construction site by first assembling the rails on the sleepers, and then welding the rail joints together. More specifically, for the laying of seamless lines, the short rails are first welded: the rail welding factory welds the standard rails (generally 25m in length) to the long rails in the factory (for the convenience of loading and unloading and transportation, generally within 500m) . After the long rails are transported to the laying site, the long rails are first assembled to the sleepers, and then the long rail joints are welded together to form a seamless line. [0003] In order to ensure the safety of driving, the joints welded by the rails at the construction site need to ...
