Abstract
The utility model provides a kind of rail that can reduce junction operation noise, including rail head, the web of the rail and rail bottom, is machined with one section of link slot respectively along rail both ends central axes direction, and the binding face of the link slot at rail both ends is towards on the contrary, dimensions is identical；Bolt hole is respectively equipped on the steel rail web of link slot binding face and close link slot.The utility model changes the drawbacks of traditional rail seamed connection, the noise generated when can greatly reduce rail connection locomotive operation, and is easy to laying construction and replacement.
Description
Technical field
The utility model, which belongs to transportation rail field more particularly to one kind, can reduce rail connection locomotive operation and make an uproar
The rail of sound.
Background technique
On solving the problems, such as that rail expands with heat and contract with cold, linking between existing track for a train rail two kinds of sides nothing more than
Formula, one is seamless weldings；Another kind is seamed connection.Seamless connection can make entire track be connected, and increase track
Globality and intensity, and the operation noise of rail junction train is effectively prevented, keep train running more steady.But its defect
Be be laid with when production cost and technical costs threshold it is very high.Seamed connection is that there are certain in the joining places of two section rail
Gap, this is also most traditional rail connection type., convenient for being laid with and replacing, construction cost and technical requirements are low for it.But it is seamed
The major defect of connection is that seam crossing can generate the problems such as noise in train running.
Summary of the invention
The utility model is intended to provide a kind of rail that can reduce rail connection locomotive operation noise.
For this purpose, the utility model takes following technical solution:
A kind of rail reducing junction operation noise, including rail head, the web of the rail and rail bottom, along rail both ends central axes side
To being machined with one section of link slot respectively, and the binding face of the link slot at rail both ends is towards on the contrary, dimensions is identical.
Bolt hole is respectively equipped on the steel rail web of rail both ends link slot binding face and close link slot.
The utility model has the following beneficial effects:
The utility model changes the drawbacks of traditional rail seamed connection, by one of steel rail ends junction lateral vertical masonry joint
Become the connection type of the additional one section of longitudinal joint of two and half transverse joints, longitudinal joint is consistent with wheel traffic direction, therefore will not generate
Noise, and half transverse joint be due on wheel still may operate at other half rail, it, can pole compared with traditional seamed connection
The noise generated when big reduction rail connection locomotive operation, while compared with seamless connection, the utility model, which is easy to be laid with, to be applied
Work and replacement, technical requirements are low, can reduce construction cost.
Detailed description of the invention
Fig. 1 is steel rail end stereoscopic schematic diagram；
Fig. 2 is steel rail end schematic cross-sectional view.
In figure: rail head 1, the web of the rail 2, rail bottom 3, bolt hole 4, link slot binding face 5.
Specific embodiment
As seen from Figure 1, the rail that can reduce junction operation noise is still to be made of rail head 1, the web of the rail 2, rail bottom 3.This
Utility model is to process one section of link slot, and the connection at rail both ends respectively along rail central axes direction at the both ends of rail
The direction of slot binding face 5 is on the contrary, dimensions is identical, in order to being correspondingly connected with for rail both ends.Meanwhile in link slot binding face
5 and close to link slot steel rail web 2 on be respectively equipped with bolt hole 4.
When rail connects, the link slot binding face 5 of two rail is fit together in opposite directions, and by the connection of two rail
Bolt hole 4 on slot binding face 5 and the web of the rail 2 is to just, and then the rail clamp with corresponding bolt hole is installed in two sides respectively, most
Rail clamp is fixed on steel rail web 2 with bolt again afterwards.Rail clamp inward facing surface shape and size and rail
The shape and size that rail head 1, the web of the rail 2, rail bottom 3 are collectively formed are corresponding.
Claims (1)
1. one kind can reduce the rail of junction operation noise, including rail head, the web of the rail and rail bottom, which is characterized in that along rail two
End central axes direction is machined with one section of link slot respectively, and the binding face of the link slot at rail both ends is towards on the contrary, dimensions
It is identical；Bolt hole is respectively equipped on the steel rail web of rail both ends link slot binding face and close link slot.
