Abstract
The invention discloses an elastic concrete sleeper which comprises a concrete sleeper; two rows of bolt holes used for fixing a fastener system are respectively formed at the two sides of the concrete sleeper; and an elastic device is arranged on a rail on the concrete sleeper between the two rows of bolt holes. The elastic concrete sleeper reduces the vibration and the noise caused during the train operation, and buffers the impact force to a track bed, thus prolonging the service life of the track bed and reducing the maintenance rate.
Description
Technical field
The present invention relates to the railway equipment technical field, especially a kind of elastic concrete sleeper.
Background technology
The modern railways transportation is more and more stricter to the requirement of track, and as high ride, high stability, high-durability, and along with existing railway transport capacity is strengthened gradually, the damage of railway roadbed constantly aggravates, and maintenance time is fewer and feweri; Causing main cause that railway roadbed damages is that train of enhanced load due to high-speed motion constantly clashes into rail, and rolling for rigidity between the two contacts, and there is no buffering course, and even covibration is serious to cause the railway roadbed vibration-generating.Therefore, in the urgent need to improving existing railroad track situation, in the advancing the track life-span, reduce maintenance rate.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of elastic concrete sleeper, can reduce maintenance rate, the advancing the track life-span.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of elastic concrete sleeper, comprise concrete sleeper, the both sides of this concrete sleeper are equipped with two row's bolts hole of attachment fastener system, settle the rail place to be provided with elastic device on the concrete sleeper between this two rows bolt hole.
Further, this elastic device is elastomer or high resiliency spring.
Further, this elastomer is thermoplastic elastomer (TPE) or polyurethane sheet material.
Further, this elastic concrete sleeper is provided with groove, and this elastic device partly is located in this groove.
Elastic concrete sleeper of the present invention arranges elastic device on the sleeper of rail installation place, and be that the sort of larger active force issues the elastic device of giving birth to less deformation, make to cross at train and reduced impact shock, alleviated the impact force to railway roadbed, reduced simultaneously noise.
Compared with prior art, the present invention has the following advantages: the vibration when having reduced train operation and noise, and cushion the impact force to railway roadbed, thereby extended the application life of railway roadbed, reduced maintenance rate.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of elastic concrete sleeper as shown in Figure 1 comprises concrete sleeper 1, and the both sides of this concrete sleeper 1 are equipped with two row's bolts hole 2 of attachment fastener system, settles the rail place to be provided with elastic device 3 on the concrete sleeper 1 between this two rows bolt hole 2.
In Fig. 1, this elastic device 3 is elastomer, as thermoplastic elastomer (TPE) or polyurethane sheet material; In actual applications, also this elastic device 3 can be made as the high resiliency spring.
This elastic concrete sleeper 1 is provided with groove, and the part of this elastic device 3 is located in this groove.
