Abstract
The utility model discloses a shock-free steel rail butting structure, which comprises steel rails, steel rail butting lines and steel rail butting angles, and is characterized in that oblique lines are butted at steel rail butting seams, and the inner angle between each butting line and each steel rail is 70-30 degrees. The steel rail port butting seams are twisted at an angle, and wheels no longer fall into the seams to generate shock only if the lengths of the contact lines of the wheels and the steel rails are greater than the widths of the seams in the running process, so that the vibration and the noise can be reduced. The shock-free steel rail butting structure is reasonable in design and convenient to implement and realize, and has a certain economic benefit, especially the social benefit. To overcome the shortage, the shock-free steel rail butting structure capable of greatly reducing shock of a train in the running process to reduce the vibration and the noise is provided.
Description
Technical field
The utility model relates to the angle of docking between rail and adjacent rail, and specifically a kind of rail is without impacting docking.
Background technology
Be in operation maximum vibration and noise of train comes from the impact that the joint between rail and rail produces, and for addressing this problem in recent years, rail also implemented multiple reform, but all not have from more dealing with problems.Think because train wheel and contacting of steel are that one and the axis of rail become the straight line of 90 ° through observation analysis for many years, and a rail port joint formed gap is also to become the straight line of 90 ° with the rail axis, this two line is in full accord, therefore the wheel discontinuity that is in operation falls in this gap, produces impact shock.
The utility model content
Figure purpose of the present utility model is to overcome above-mentioned deficiency, thereby the impact that provides a kind of decrease train to be in operation alleviates the rail of vibration and noise without impacting docking.
How the technical solution of the utility model realizes: a kind of rail comprises rail, track bond line and angle thereof without impacting docking, it is characterized in that track bond seam place, and with the oblique line docking, on its butted line and rail, the interior angle angle is 70 °-30 °.
Being about to rail in Rail Production, to be cut into incline direction consistent, the angled end-face that angle is identical (angle on request), just form after implementing docking one with axis parallax gap, the length in oblique line gap is relevant with the size at the ratio of width and oblique angle, angle is less, width can be less in same end play, for the end face that do not make rail too point and the cross section too large, on butted line and rail, the inner clip angle adjustment is advisable to appropriateness.
Description of drawings
FigureThe 1st, structural representation of the present utility model.In figure 1, rail; 2, butted line 3, butt joint 4, interior angle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail
Shown in figure, oblique line docking rail comprises rail 1, butted line 2 and angle thereof.Its rail 1 docks with joint oblique line between rail 1, and on its butted line 3 and rail, interior angle 4 is 70 °-30 °.Being about to rail in Rail Production, to be cut into incline direction consistent, the angled end-face that angle is identical (angle on request), just form after implementing docking one with axis parallax gap, the length in oblique line gap is relevant with the size at the ratio of width and oblique angle, angle is less, width can be less in same end play, for the end face that do not make rail too point and the cross section too large, on butted line and rail, the inner clip angle adjustment is advisable to appropriateness.
