Background technology
When train passes through bridge, bridge will vibrate, and then pass to ground by Bridge Pier.
Flourish along with track traffic, vibration that is produced by train operation and noise also more and more are subject to people's attention the influence of environment; Reducing the vibration of track traffic and reduce noise, is the quality of life that improves resident along the line, the key subject of protecting railway surrounding enviroment and track traffic sustainable development; It is one of important vibration isolation measure that vibration isolating suspension is set between bridge and pier.
Vibration isolating suspension is that railroad bridge subtracts the vitals in the vibrating isolation system, and its performance directly influence subtracts vibration isolating effect; The rubber vibration isolating suspension that most employing elastomeric material is made in the prior art is as isolation mounting, because the elasticity and the damping characteristic of rubber, make the rubber damping bearing to subtract vibration isolating effect very outstanding, particularly the excellent anti-vibration performance that subtracts is arranged for dither, yet railroad bridge should have enough lateral stiffnesses, to prevent the comfortableness of vehicle derailing and assurance vehicle operating, this requirement is more important for gapless track; But existing rubber vibration isolating suspension is to satisfy horizontal movement and less horizontal rigidity is provided by shear strain, can't satisfy the requirement of special line for passenger trains.
CN200620163864.6 discloses a kind of rubber vibration isolating suspension, it is provided with wear-resisting slide plate, slide between anchor plate and slide plate in the dependence and realize displacement, but it still lacks rigidity in the horizontal direction, can not bear big transverse horizontal power, usually need and one be exclusively used in the device (as the shearing tenon) that bears horizontal force and be used together, make troubles to installing and using.
Summary of the invention
The purpose of this utility model is to propose a kind of railroad bridge with unidirectional sliding-type vibration isolating suspension, makes its vibration isolation requirement that can satisfy bridge, and has the characteristics of opposing horizontal force, realization rotating function.
The utility model is for finishing its invention task by the following technical solutions:
A kind of railroad bridge mainly comprises upper base plate, vibration isolation rubber body and following seat board with unidirectional sliding-type vibration isolating suspension, described vibration isolating suspension; Described upper base plate is the U type that interlocks with following seat board, the seat board two ends have the block of protrusion respectively up and down, constitute horizontal force resistant mechanism, and paste at guiding stainless steel slide plate on the upper base plate block and the low friction of the guiding slide plate that is embedded on the seat board block down and constitute the guiding friction pair; Described vibration isolation rubber body between upper base plate and following seat board has upper sealing plate and following shrouding; The described plane stainless steel slide plate that pastes in the upper base plate bottom surface constitutes the planar friction pair with the plane low friction slide plate that is embedded in the upper sealing plate; Described shrouding down is connected as a single entity with following seat board.
The bottom of shrouding has round boss under described vibration isolation rubber body, and corresponding described round boss has the cylinder groove of joining with its kissing on the seat board down, and described round boss is embedded in down in the cylinder groove of seat board.
Described vibration isolation rubber body is a cylinder.
Described vibration isolation rubber body is a cuboid.
The low friction in described plane slide plate, the low friction of guiding slide plate are the polytetrafluoroethylene (PTFE) slide plate.
The low friction in described plane slide plate, the low friction of guiding slide plate are the modified ultra-high molecular weight polyethylene slide plate.
A kind of railroad bridge that the utility model proposes is with unidirectional sliding-type vibration isolating suspension, employing has the vibration isolation rubber body of given vertical dynamic and static rigidity, by changing the rigidity of system, and then the intrinsic frequency of change system, can reduce the influence of superstructure vibration, realize bridge vibration isolation function basis and surrounding enviroment.By horizontal force resistant mechanism and guiding friction pair are set, make bearing have big horizontal rigidity simultaneously, spacing direction horizontal force can be born, and control can be realized direction of displacement; By the secondary support displacement of realizing of planar friction, friction factor is low, and the slip resistance of bearing main displacement direction is little, has avoided the big shear strain of rubber bodies simultaneously, and then the application life of having improved bearing; And have installation, characteristics easy to use.
