Description
Technical field
The present invention relates to field of track traffic is belonged to, more particularly, to one kind for frequency modulation rail damper to be fixed on steel
Clip on rail.
Background technique
Since the rapid development of rail traffic allows train operation route to be increasingly closer to residential block, the then vibration of train operation
The adverse effect that dynamic and noise problem lives to people is increasing.Existing mass data shows vibration and the noise of train operation
Greatly the injustice from Wheel Rail Contact is pliable, and then some scholars have developed frequency modulation rail damper effectively to administer
The noise of track and vibration.Most frequency modulation rail damper is mounted on steel rail web two sides, this just it is installed after can
Requirement is proposed by property, use cost and the convenience of installation and removal.
Currently, to the mode that the installation of frequency modulation rail damper mainly has bonding and fixed with clip, patent
Dynamic vibration-absorbing multilayer damping-constraining steel rail silencer disclosed in CN200610023902.2 is exactly with the method for bonding, later period
Maintenance is difficult, is difficult to re-use after disassembly.It is flexible, reusable using clip mode, but patent
CN201220171742.7 is disclosed for steel rail vibration damping device to be fixed on the clip on rail, due to using band-like, life
Processing difficulties are produced, what is used is at high cost, and the pressing force that single clip provides is smaller, not very firm after installation.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of production and processings simply,
It can be directly made of the metal material bending of corresponding size, being used for frequency modulation for structure is enormously simplified while improving pressing force
Rail damper is fixed on the clip on rail.
The purpose of the present invention can be achieved through the following technical solutions:
It is a kind of for frequency modulation rail damper to be fixed on the clip on rail, including sequentially connected first clamping section,
First connection circular arc, the second clamping section, the second connection circular arc and third clamping section；First clamping section is fitted tightly over tune
The top surface of frequency rail damper, the second clamping section are pressed on frequency modulation rail damper side, third clamping section and rail rail bottom bottom
Face fits closely, and the frequency modulation rail damper and rail rail bottom and steel rail web are in close contact, and clip bilateral symmetry is
One entirety, the end of the third clamping section further include third U-shaped end, and the end of first clamping section is additionally provided with
One U-shaped end.Arc-shaped and the first compressed part, the third compressed part of second clamping section of the clip generate pressing force jointly.
Further, the outer profile of first clamping section is 15-50mm along the length of rail transverse direction.
Further, the first U-shaped end is box or circular arc, the symmetric part of left and right two along rail it is longitudinal away from
From for 12-320mm.When using box, the straightway of box is connect with the rest part of the first compressed part with arc transition.
Further, the first U-shaped end and the top surface of frequency modulation rail damper are in close contact.
Further, the third U-shaped end is fitted closely with rail rail bottom side, when installation the U-shaped end play positioning,
Snap action.
Further, second clamping section is arc-shaped, and the arc-shaped convex portion compresses frequency modulation rail
The side of damper.
Further, the angle of the third clamping section and the first clamping section place plane is 0-30 °.
Further, the first connection circular arc, the second clamping section, the second connection circular arc, third U-shaped end are respectively positioned on
In orthographic projection region.
Further, which is bent by the metal pipe material that section is circle, triangle or quadrangle, preferably round
Shape.
Further, the clip is preferably made of spring steel material.The song of each section of connection circular arc of the clip
Rate radius is determined according to the actual outer dimensions of frequency modulation rail damper.
Above-mentioned clip is directly prepared by the metal of corresponding size, and the bilateral symmetry shape of use can provide bigger pressure
Clamp force, it is more firm that symmetrical pressing section can also make to compress distance away.
Compared with prior art, the invention has the following advantages that
(1) frequency modulation rail damper is fixed on rail using clamping mode, solves what adhesive method was easy to fall off
Defect；
(2) stability and reliability of clamping be ensure that using design symmetry, while simpler than band-like clip structure
Change, more easily produces；
(3) first clamping section of this clip and the top of frequency modulation rail damper are in close contact and than the first of band-like clip
The contact area of clamping section is bigger, to make to clamp more stable, reliable；
(4) structure that clip simplifies makes to install more flexible, easy.
