Description
Technical field
The utility model relates to a kind of low noise flexible rail fastening devices, belongs to the flexible rail technical field.
Background technology
High-speed rail transportation can not only improve traffic environment effectively, makes things convenient for the people to go on a journey, but also helps to drive town and country construction and economic development, has remarkable economical and social benefit.Simultaneously Rail Transit System also can be inevitably brought such as the problem of noise, vibration, electromagnetic radiation and influenced view to urban and rural environment, and is wherein particularly outstanding with noise in the train driving and vibration effect.Excessive noise will have a strong impact on the passenger with vibration and track people along the line live normally; On the other hand, noise and vibration also may cause the fatigue damage of relevant devices and structure and surrounding building, reduction of service life.
At present, in subway, lay " steel spring floating slab ", it is a kind of more satisfactory absorption vibration denoise method, reach 30dB according to German field data damping, this system is a kind of quality a---spring system, its basic principle is exactly oscillating mass and the elasticity that increases vibrating body, utilizes its inertia force to absorb impact load, thereby plays the vibration isolation effect.The multiplication factor of this vibrating isolation system under basic vibration frequency is very low, so the effect of vibration and noise reduction highly significant.This method is used in the city of states such as Germany, France, Britain, and is respond well.This method has also been adopted in some track traffics on ground such as Beijing and Shanghai; But because its cost too expensive, every kilometer reaches more than 1,000 ten thousand yuan.
Domestic in addition a lot of city rails adopt some fasteners to fix, and this structure can play the effect of certain vibration and noise reducing, but its result of use is obvious inadequately.
Summary of the invention
For the problem of noise pollution, the utility model provides a low noise flexible rail fixation clip.This pressure plate structure is simple, can effectively reduce the noise that produces when train is walked in orbit.
The technical solution adopted in the utility model is: a kind of low noise flexible rail fastening devices, adopt the track pressing plate that track is fixed on the basis in the track both sides.The bottom on described basis is a cement, and pre-embedded bolt and track follower bolt are set in cement, is provided with clay and billet successively on cement top, is provided with track rubber cushion plate between rail and billet; With the fastening billet of described pre-embedded bolt, pass through pressing plate base and the fastening track of track pressing plate with described track follower bolt.
Described track pressing plate adopts single bolt track pressing plate or two bolt track pressing plate.
Described track rubber cushion plate adopts structure of steel pole.
Described track pressing plate is provided with by vulcanization fixing rubber nose and rubber pad.
Described pressing plate base is provided with heightens the inclined-plane.
Described billet is provided with the adjustment bolt and lock nut.
Adopt the guiding theory of technique scheme to be: billet is laid on the cement ground that has watered special clay, this clay is compared with ordinary concrete, intensity is higher, quality is more closely knit, whole system just is placed in one more on the firm foundation like this, the vibration that produces during the operation of reduction equipment has also reduced because vibration produces the possibility of noise.
Low noise flexible rail fixed system is positioned over the rubber cushion plate between billet and the track.Be used to bear the track pressure at right angle, reduce vibration and noise.Because rubber has unique viscoelastic behavior in very wide temperature range, not only can absorb stores impact energy by elastic deformation as steel spring, but also can be by the strand relative motion and consumed energy significantly.Elastomeric material has high strength, anti-creep, endurance and ageing-resistant characteristic.
In track pressing plate and track upper surface contact site, have by the fixing rubber nose of vulcanization, with the rubber nose track is pushed down with certain pretightning force during installation, under the acting in conjunction of rubber mat plate, bear the power of track vertical direction, because the elasticity of rubber, can reduce the amplitude of rail, thereby reduce noise.
In the horizontal direction, a rubber pad has been fixed by vulcanization in track pressing plate side, because pressing plate base and track pressing plate contact surface are the inclined-plane, so just make the track pressing plate that the space of regulating has been arranged, at first when track is installed, can guarantee the accurate of track space, secondly can be according to the difference of track stress condition, regulate the decrement of side rubber, make track bear suitable pretightning force,, best stress is arranged all so no matter at vertical plane or horizontal plane.
Rail integral solder in the low noise flexible rail fixed system, vibration that produces when avoiding locomotive to pass through seam and noise.
The beneficial effects of the utility model are: this low noise flexible rail fastening devices adopts pre-embedded bolt and track follower bolt is set in cement, is provided with clay and billet successively on cement top, is provided with track rubber cushion plate between rail and billet; With the fastening billet of pre-embedded bolt, pass through pressing plate base and the fastening track of track pressing plate with the track follower bolt.This device for fixing running tracks is at rail and pressing plate contact point, play the effect of damping and uniformly distributed load by high-strength rubber, the track daylight opening can be adjusted simultaneously, make track bear certain pretightning force, the vibration and the noise that produce when the equipment that greatly reduces is walked in orbit, also improve simultaneously the application life and the safety factor of fixed system, had great economic benefit.
