Abstract
The utility model relates to a rail double-layer nonlinear shock-absorbing and noise-lowering fastening, which comprises an elastic bar and an insulation bearing block. The utility model is characterized in that an elastic bar hole is arranged on the two sides of an upper armor plate. The elastic bar is arranged in the elastic bar hole. An elastic bearing plate is arranged on the upper armor plate. A bulging roof is arranged on the lower parts of two sides of the upper armor plate. An elastic cover is covered on the outside of the bulging roof. The elastic bearing plate is arranged under the upper armor plate. A bottom plate is under the elastic bearing plate. Two holes, which are corresponding to the bulging roofs on the upper armor plate, are arranged on the bottom plate. A gland is arranged on the hole of the bottom plate and is connected with the bulging roof of the upper armor plate through a bolt. A layer of a vertical steering plate is arranged under the bottom plate. Traversing lock adjusting holes are arranged at the two ends of the bottom plate. The bolt is arranged in the traversing lock adjusting hole and is connected with a sleeper. The utility model has the advantages that horizontal and vertical elasticity (nonlinearity) are provided to absorb the shock of a rail; the shock noise is reduced when a train passing by; the excellent torsional rigidity of the rail is kept and the safety of a traveling crane is ensured.
Description
Technical field
The utility model relates to a kind of rail clip, the double-deck nonlinear vibration reduction denoising fastener of particularly a kind of track.
Background technology
The great development of urban track traffic at present, elevated railway is passed through intown, because the hysteresis of existing track equipment, the track traffic speed of a motor vehicle improves constantly, again near the resident compact district of living, vehicle wheel and the track vibration of sending and produce bigger noise under steam, have a strong impact on people's life, though and between rail and sleeper, can reduce vibrating noise with softer material cushion, but cross the soft torsional stiffness that can influence track, can bring traffic safety hidden danger, and cushion be compressed the effect that can lose vibration and noise reducing firmly or with firmware.
Summary of the invention
The purpose of this utility model is the great development that solves urban track traffic in the prior art, elevated railway is passed through intown, because the hysteresis of existing track equipment, the track traffic speed of a motor vehicle improves constantly, again near the resident compact district of living, vehicle wheel and the track vibration of sending and produce bigger noise under steam, have a strong impact on people's life, though and between rail and sleeper, can reduce vibrating noise with softer material cushion, but cross the soft torsional stiffness that can influence track, can bring traffic safety hidden danger, and hard or cushion is compressed the problem of the effect that can lose vibration and noise reducing with firmware.The double-deck nonlinear vibration reduction denoising fastener of the utility model design track, comprise spring, cross-over block, it is characterized in that: there is the spring hole both sides of going up iron plate, spring has spring in the hole, the top flexible backing plate of last iron plate, two side lower parts of last iron plate have the top of protrusion, protrude the flexible cover of top overcoat, the following flexible backing plate of last iron plate, resilient sleeper-bearing for base plate, has two protrusions with last iron plate to push up corresponding hole down on the base plate, the protrusion top that connects iron plate at the gland on the hole of base plate by nut, have one deck to heighten plate below base plate, there is horizontal locking-type adjustment hole at the two ends of base plate, laterally have bolt to connect sleeper in the locking-type adjustment hole.The utility model has the advantages that can be vertical and laterally provide elasticity (strong nonlinearity) to absorb rail vibration, make train by the time reduce vibrating noise, can keep good track torsional stiffness again, guarantee traffic safety.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing is structural representation of the present utility model (bilateral symmetry is omitted the right side)
Comprise spring 1 among the specific embodiment figure, cross-over block 2, it is characterized in that: there is spring hole 4 both sides of going up iron plate 3, spring 1 is arranged in the spring hole 4, the top flexible backing plate 5 of last iron plate 3, two side lower parts of last iron plate 3 have the top of protrusion 6, protrude the flexible cover 7 of top 6 overcoats, the following flexible backing plate 8 of last iron plate 3, resilient sleeper-bearing is for 8 times a base plate 9, there are two protrusions to push up 6 corresponding holes 10 on the base plate 9 with last iron plate 3, the protrusion top 6 that connects iron plate 3 at the gland 11 on the hole 10 of base plate 9 by nut 12, below base plate 9, there is one deck to heighten plate 12, there is horizontal locking-type adjustment hole 13 at the two ends of base plate 9, laterally have bolt 14 to connect sleeper 16 in the locking-type adjustment hole 13, provide and heighten on a large scale and the gauge adjusting.Spring 1 is pushed down rail 15 by cross-over block 2 during use, when train passes through, resilient sleeper-bearing 5 forms an elastic system spare of connecting with resilient sleeper-bearing 8, can improve effectiveness in vibration suppression greatly, last iron plate 3 is connected base plate 9 by gland 11 with nut 12 by protruding top 6, and this fastener can provide and bear uplift force, the damping elastomer of vertical direction to greatest extent under the situation that guarantees torsional stiffness, push up 6 outer resilient sleeve 7 and protrude, can realize the vibration and noise reducing of horizontal direction again.
