Steel rail rubber vibration and noise reduction insertion strip

Abstract

The invention relates to a steel rail rubber vibration and noise reduction insertion strip. The steel rail rubber vibration and noise reduction insertion strip comprises edge strips and intermediate strips, wherein the edge strips are arranged at non-working edges of steel rails, and the intermediate strips are arranged at working edges of the steel rails; each edge strip comprises an edge strip body, one side of each edge strip body outwards stretches out of an edge strip flange, and the lower side of each edge strip flange is provided with a notch; each intermediate strip comprises an intermediate strip body, one side of each intermediate strip body outwards stretches out of an intermediate strip flange, the upper side of each intermediate strip flange is provided with a rim channel, and the lower side of each intermediate strip flange is provided with a notch. According to the steel rail rubber vibration and noise reduction insertion strip disclosed by the invention, the structure is simple, and the use is convenient; the edges of the steel rail rubber vibration and noise reduction insertion strip are meshed with rails, fasteners can be effectively protected due to grooves arranged under the edges, the service life of a product can be further prolonged, the failure rate can be reduced, and the cost is lower.

Description

technical field [0001] The invention relates to consumables used on both sides of rails, in particular to a rail rubber vibration-reducing and noise-reducing insert, which can be used on both sides of rails and is mainly used in major railway lines, subways, ports, docks, platforms, steel Factories, freight yards, locomotive depots, mines, etc. Background technique [0002] The railway crossing is the main throat in the railway transportation and the road transportation. For many years, asphalt, concrete slab brick and steel structure slab pavement are mostly used. Along with the day by day development of railway, highway transportation industry, the shortcoming of these crossing slabs is exposed day by day. It is mainly manifested in the following points: the strength of the asphalt pavement is weak, and it will be scattered and damaged after long-term heavy pressure; the interconnection of concrete slabs and bricks and the combination between the rails and the roadbed are...

AI Technical Summary

Problems solved by technology

It is mainly manifested in the following points: the strength of the asphalt pavement is weak, and it will be scattered and damaged after long-term heavy pressure; the interconnection of concrete slabs and bricks and the combination between the rails and the roadbed are not reliable, and it is easy to loosen and break; the steel structure The surface is slippery and the cost is higher

[0003] With the continuous development of railway technology, the speed of trains is getting faster and faster. These existing crossing settings are difficult to meet the higher requirements of rails for vibration and speed.
