Steel rail nondestructive reinforcing equipment

Abstract

The invention discloses steel rail nondestructive reinforcing equipment which comprises an elastic clamp, a clamping plate and high-strength adhesives, wherein the elastic clamp is formed by being bent integrally. Geometrical shapes of the inner side, the upper side and the lower side of the clamping plate are matched with those of the middle part, the lower jaw and the rail bottom top surface of a steel rail respectively, the clamping plate adheres to the steel rail through the high-strength adhesives to form a whole, and the clamping plate is firmly locked on the steel rail through the elastic clamp. The steel rail nondestructive reinforcing equipment has the advantages that additional damage of drilling to the steel rail is avoided, reinforcement of the steel rail and a damaged steel rail at a weld joint is achieved under the undamaged condition, dynamic stress and bending stress of the steel rail are effectively reduced, and crack propagation and fracture of the steel rail and the damaged steel rail at the weld joint are prevented; clamping force is constant, the structure is simple, installation is convenient to carry out, and later maintenance loads are small; weld joints can be avoided; installation is free from the height restriction of a steel rail bottom surface ballast bed and the surface of a rail board, and the equipment can adapt to ballast tracks and various types of ballastless tracks; the equipment can be applied to nondestructive reinforcement of rail transit project intervals such as high speed railways, general speed railways, heavy haul railways and urban rail transit and steel rails in forked areas.

Description

technical field [0001] The invention belongs to the technical field of railway rail damage reinforcement, and in particular relates to an elastic clip-type non-destructive reinforcement device for bolt-less rails that prevents weld seam damage and fracture of various line rails and other damage fractures. Background technique [0002] With the development of high-speed railways, heavy-duty railways, ordinary-speed railways and urban rail transit in China, due to factors such as rail rolling, rail bumps during train transportation, damage during operation, and rail weld fractures, rails are prone to light Injury, especially at the welded joint of the rail as the weak link of the rail structure (the strength of the weld is difficult to reach the same strength as the base metal of the rail). [0003] Because the slightly injured rails are not replaced before the seriously injured standards, but if no reinforcement measures are taken for them, their sudden fracture will directly...

AI Technical Summary

Problems solved by technology

On the one hand, this method uses bolts for fastening, which requires regular oiling and re-tightening of the bolts, which increases the workload of maintenance and repairs in the later stage; Additional damage, which usually manifests as microscopic cracks, is difficult to find. In severe cases, the rail is prone to sudden fracture, threatening driving safety

[0004] The way to solve the problem of additional damage to the rails caused by the above reinforcement methods is to install non-destructive reinforcement equipment for rails. However, the splint locking devices of the existing non-destructive reinforcement equipment for rails all adopt bolt fastening structures, which are complex and heavy and inconvenient to install on site; The clamping force is unstable and attenuates quickly, which greatly reduces the effect of rail damage reinforcement. In addition, frequent inspection and maintenance are still required
