Description
Technical field
The present invention relates to rail traffic vibration and noise reducing fields, hinder more particularly, to a kind of rail based on quality enlarged structure
Buddhist nun's device.
Background technique
Running train, which can generate percussion to track, will lead to the vibration of track, and track vibration can generate noise pollution,
The speed that train traveling can be also reduced while orbital lifetime is influenced, in addition, train vibration also will cause a large amount of negative effect.
With a large amount of construction of urban track traffic, more and more rail lines are closed on or even are passed through and need to carry out vibration control
Building, the REDUCTION OF VIBRATION in train traveling process becomes more and more important.Currently, vibration control is mainly subtracted by track
Vibration, route of transmission vibration isolation and progress in terms of by vibration body (building etc.) vibration isolation etc. three.Track vibration-reducing measure from vibration source angle,
Have to ambient vibration control effect and directly affect, by rail damper, wheel-rail contact relationship can be improved, row is effectively reduced
Vibration and noise caused by vehicle, the current usual gluing of rail damper in the two sides of rail, therefore usually will appear dystopy or
The hidden danger that person falls off.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind to be amplified based on quality
The rail damper of structure.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of rail damper based on quality enlarged structure is set to rail foot, including shell, filling web plate and matter
Gauge block, wherein shell is cuboid plate structure, and inside has cavity；It fills web plate and is set to the cavity inside, by muti-piece
Metal plate interconnection is constituted, so that filling web plate is diamond-mesh structure in the section of shell longitudinal direction；Mass block: it is set to
At the interconnection of metal plate, and it is rigidly connected at interconnection with metal plate.
Further, the shell is hard rubber material.
Further, the width of the shell is equal to the width of rail foot surface.
Further, two side inner surfaces of the shell longitudinal direction are equipped with many places protrusion, and the protrusion is right
The outer surface of outer cover position answered offers the groove for grafting buckle, and the buckle is for being connected in rail bottom for shell
Portion.
Further, the bottom and top inner surface of the shell through-thickness is fixedly connected with metal plate.Gold
Belonging to plate to be on four direction all around is freely type of attachment.
Further, the mass block is rectangle bloom, and the metal plate passes through welding or bolted mode
It is fixed on mass block.
Further, the shell with a thickness of 1.5~3cm, can be adjusted according to Specific construction form, the length of shell
For 0.2~0.4m.
Further, the following table face contact at the top of the shell and rail.
Compared with prior art, the present invention provides a kind of damper with metal plate filled layer, wherein metal plate is filled out
Fill layer be made of metal plate interconnection, filling web plate the section of longitudinal direction be diamond-mesh structure, vibrational energy from
Rail foot is transferred to cover top portion, then the top of filling web plate is transferred to by cover top portion, and vibrational energy is dispersed to often later
In block metal plate, due to the toughness of metal plate and the load of mass block, so that the damping that is combined into of metal plate and mass block is shaken
Dynamic system, and the ratio of the toughness of metal plate and its size is bigger, and amplitude can be made bigger.In the vibration-damping system, by
It is different in the position of mass block, cause the phase vibrated in the region of each damping vibration different, the vibration of out of phase passes through
Metal plate carries out the dissipation that transmitting eventually leads to vibrational energy, reaches preferable effectiveness in vibration suppression with this.
On the other hand, the metal plate in the present invention need to be only embedded in below rail in specific installation, only be needed so that shell
Upper cover plate touch the lower surface of rail, and simple clamping is carried out by buckle and realizes final fixation, therefore the present invention
In damper compared to existing damper install it is more convenient, construction cost is low, fall off, the probability of transposition it is small, use the longevity
It orders longer.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
Rail damper based on quality enlarged structure is set to rail foot, including shell 1, filling web plate 2 and quality
Block 3, referring to Fig. 1 and Fig. 2.
1 part of shell: it is cuboid plate structure, and inside has cavity；The shell 1 is hard rubber material.
The width of the shell 1 is equal to the width of rail foot surface.Two side inner surfaces of 1 longitudinal direction of shell are equipped with more
Place's protrusion, corresponding 1 outer surface position of shell of protrusion offers the groove 3 for grafting buckle, described referring to Fig. 3
Buckle for shell 1 to be connected in rail foot.The bottom and top inner surface of 1 through-thickness of shell with gold
Belong to plate to be fixedly connected.Metal plate be on four direction all around be freely type of attachment.
Filling 2 part of web plate: set on the cavity inside, being made of muti-piece metal plate interconnection, referring to Fig. 1 and figure
2, so that filling web plate 2 is diamond-mesh structure in the section of longitudinal direction.
3 part of mass block: being rigidly connected at the interconnection of metal plate, and at interconnection with metal plate, ginseng
See Fig. 1 and Fig. 2.The mass block 3 is rectangle bloom, and the metal plate is fixed on by welding or bolted mode
On mass block 3.
In the specific use process: the damper being embedded in the lower section of rail, so that the upper surface of shell 1 contacts
It is inserted into groove 4 to the lower surface of rail, and by one end of buckle, the lower section of the other end engaging and rail.Vibrational energy is from steel
Rail bottom portion is transferred to cover top portion, then the top of filling web plate 2 is transferred to by cover top portion, and vibrational energy is dispersed to every piece later
In metal plate, due to the toughness of metal plate and the load of mass block, so that metal plate and mass block are combined into damping vibration
System, and the ratio of the toughness of metal plate and its size is bigger, and amplitude can be made bigger, to play the effect of quality amplification.
In the vibration-damping system, since the position of mass block is different, lead to the phase vibrated in the region of each damping vibration not
Together, the vibration of out of phase carries out the dissipation that transmitting eventually leads to vibrational energy by metal plate, reaches preferable vibration damping with this
Effect.
To the damper carry out damping frequency test data analyze, referring to fig. 4, it is seen that 300~450Hz, 600~
Make vibration transmissibility decline obvious in the frequency range of 1800 and 2200~2500Hz, i.e., has within the scope of frequencies above
Good effectiveness in vibration suppression.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
