Description
Technical field
The utility model belongs to track vibration-reducing technical field, relates to a kind of steel rail vibration reduction fastener.
Background technology
At present, China carries out on a large scale urban rail transit construction, especially urban track traffic and is related to especially daily life.When urban rail transit construction, be no matter underground line or ground line also or elevated line, when train driving is crossed residential block, hospital, Office Area, because wheel and rail impact the vibration that causes architecture communication towards periphery, near having a strong impact on, people's normal operation, life, certainly will renovate the propagation of rail vibration.At present, the peripherad propagation of reduction rail vibration is the most effective, employing the widest maximum methods are to adopt steel rail vibration reduction fastener.Because steel rail vibration reduction fastener has certain flexibility, Damping fastening generation elastic deformation when Vehicle Driving Cycle, can effectively reduce and vibrate the propagation of vibration damping towards periphery.
Yet in order to reach good effectiveness in vibration suppression, the design of steel rail vibration reduction fastener is restricted.Common Damping fastening is Double-layer elastic backing plate compression fastener or the shearing fastener of adhesion type; Double-layer elastic backing plate compression fastener is comprised of two-layer elastic layer and double layer of metal backing plate, and 4 thickness sum has formed the overall height of fastener, and the height making is higher, conventionally more than 60mm; The vibration damping of the shearing fastener of adhesion type by between upper padding plate and lower bolster and the ring elastic body of placing backing plate setting realize, in order to reach good adhesive effect, must increase elastomeric lifting surface area by increasing elastomeric height, therefore the height of fastener is higher, even surpasses 80mm; When the existing line of employing conventional fastener is carried out to Damping fastening transformation, due to the structure that conventional fastener only adopts one deck iron chair, a laminate lower bolster and one deck railway rail pad to form, the about 40-46mm of setting height(from bottom).So just there is problem: be difficult to make track setting height(from bottom) parameter to mate with original design, need to adjust whole piece line parameter circuit value, track remodelling construction is caused to very burden, improvement cost is high, necessary this problem has been solved.
In addition in traditional adhesion type fastener, Double-layer elastic backing plate shearing-type fastener particularly, as the publication number sleeper damper that is CN2045756U; Support rail plate be the bottom bonding plane of upper padding plate be back taper, lower bolster with it corresponding bonding plane be equally back taper design, the double action that causes the elastic body between them to be sheared and compress at vertical direction, according to rubber elastomer characteristics, when elastic body is when vertical direction is subject to shearing completely, its contribution to vertical direction rigidity is minimum; And when vertical direction is compressed, the contribution of vertical direction rigidity is obviously increased.Therefore, need to make elastic body be subject to vertical shear strain as far as possible, reduce as far as possible the compressive strain of in the vertical direction.
Utility model content
In order to address the above problem, the purpose of this utility model is to propose a kind of steel rail vibration reduction fastener.
The utility model adopts following technical scheme for completing above-mentioned purpose:
A steel rail vibration reduction fastener, described steel rail vibration reduction fastener includes upper padding plate, lower bolster and spring mount pad and spring; Described lower bolster is fixed on railway roadbed basis; The middle part of described lower bolster has the groove corresponding with described upper padding plate shape or through hole; The bottom of described upper padding plate is positioned at the above groove or through hole of lower bolster; Between described upper padding plate and described lower bolster, elastic body I is set, and in the gap that has between upper padding plate and the internal face of the above groove of lower bolster or through hole, the bottom of described elastic body I; Corresponding described upper padding plate arranges elastic body II; Described elastic body II is positioned at the through hole described in lower bolster, and makes described elastic body II be positioned at the bottom of described upper padding plate, or described elastic body II is in the described groove of lower bolster and between upper padding plate and the groove floor of lower bolster.
Between described lower bolster and described railway roadbed basis, be provided with coupling backing plate, described elastic body II is between described upper padding plate and described coupling backing plate.
The two ends that described lower bolster upper surface is vertical with steel rail laying direction all have position limiting structure; The described position limiting structure that described lower bolster has has a restriction upper padding plate and at vertical direction, moves spacing confined planes II along confined planes I and the restriction upper padding plate that vertically steel rail laying direction moves; Described confined planes II is positioned at the top of described confined planes I and inwardly stretches out; Described confined planes II is that arcwall face or described confined planes II are inclined-plane perpendicular to described confined planes I or described confined planes II.
The bonding surface of described elastic body I and described confined planes I and the shape of described confined planes I kiss are joined.
The bonding surface II of the groove described in lower bolster or the internal face of through hole and elastic body I, be arranged in described in lower bolster groove or the upper padding plate bottom of through hole and the bonding surface I of elastic body I and have at most one for inverted cone surface, in described bonding surface I and bonding surface II, have at most one for inverted cone surface.
A kind of steel rail vibration reduction fastener the utility model proposes, in the groove of lower bolster or through hole, elastic body II is set, and described elastic body II is positioned at the bottom of upper padding plate, make Damping fastening mainly rely on the elasticity of compression distortion of elastic body II to provide in vertical direction rigidity, and then reduced the setting height(from bottom) of whole steel rail vibration reduction fastener; In order further to reduce the compression that above-mentioned elastic body I is subject to, in the utility model, in the bonding surface II of the bonding surface I of upper padding plate and elastic body I, lower bolster and elastic body I, have at least a face not adopt back taper face, so just further reduced the compressive deformation of elastic body I in the vertical direction.
