N-shaped steel rail connector

Abstract

The invention relates to a novel rail connecting technology, in particular to an N-shaped steel rail connector which is characterized in that the N-shaped steel rail connector comprises two complementary triangles, two steel rail end heads which are connected in an abutting mode have corresponding oblique angles larger than or equal to 45 degrees, according to the physics law which is that effect between objects is mutual and via a mathematical geometric principle, defects such as noise caused by impact because of gaps, which exist in a seamed rail connection are overcome, pollution to environment is avoided fundamentally, and potential safety hazards and the like can be avoided. The N-shaped steel rail connector can also be used for the connection of modern high-speed railway steel rails and rails of mine rail transport, port gantry cranes and the like.

Description

technical field [0001] The invention relates to the field of railway construction, in particular to an N-shaped rail interface. Background technique [0002] The current railway rail interface is conventionally H-shaped connection. Due to the thermal expansion and cold contraction of the rail, expansion joints are reserved at both ends of the rail, and the expansion joints collide with the wheels when driving to make a "click, click" sound. The noise produced seriously affects the living environment of passengers and people along the railway line; in addition, the direct collision of rail joints also brings a lot of loss. According to incomplete statistics from relevant departments, more than 60% of rail damage occurs at the joints, and the repair cost is about It accounts for more than 70% of the total maintenance cost of the line. Another type of interface is welded seamless rails, which means that the long rail section itself bears all the temperature stress, that is, th...

[0002] The current railway rail interface is conventionally H-shaped connection. Due to the thermal expansion and cold contraction of the rail, expansion joints are reserved at both ends of the rail, and the expansion joints collide with the wheels when driving to make a "click, click" sound. The noise produced seriously affects the living environment of passengers and people along the railway line; in addition, the direct collision of rail joints also brings a lot of loss. According to incomplete statistics from relevant departments, more than 60% of rail damage occurs at the joints, and the repair cost is about Accounting for more than 70% of all line maintenance costs

Another type of interface is welded seamless rails, which means that the long rail section itself bears all the temperature stress, that is, the long rail is locked on the pillow bed so that it will not expand and contract due to temperature changes. This method is suitable for temperature differences throughout the year. In small areas, this approach is often adopted in the southern regions of China, but the seamless connection track requires a solid track bed, and the cost is 1.5-2 times that of ordinary tracks, so it requires a huge investment, and it is not applicable to areas with large temperature differences
