Description
(1) technical field
The utility model relates to a kind of sleeper of traffic system.
(2) background technology
Excessive noise and vibration will have a strong impact on the passenger and track traffic people along the line live, work and have a rest, damage physical and mental health normally, reduce operating efficiency; On the other hand, noise and vibration also may cause the fatigue damage of Rail Transit System corresponding apparatus and structure and surrounding building and equipment, shorten Acceptable life.Therefore, the control of rail transit noise and vibration has become one of important content that improves passenger comfort and environmental protection.Reduce the vibration of train and vibration that noise level, minimizing track traffic cause and noise problem and just become the important problems of Rail Transit System in building.
At present, usually the noise reduction vibration isolation measure that adopts is to use elastic short rail sleeper, so-called elastic sleeper promptly adds resilient sleeper-bearing in the sleeper bottom, and adopt " gumshoe " that sleeper and resilient sleeper-bearing parcel are isolated, be laid in the track engineering, the vibration that a part is transmitted out by wheel-rail impact can be intercepted, and wheel-rail noise can be reduced.Elastic short rail sleeper can to a certain degree reduce noise minimizing vibration.Yet facts have proved that there is the deficiency of following four aspects in elastic short rail sleeper:
1. " gumshoe " adopts rubber to make, and manufacturing process need be vulcanized, and certain disposal of pollutants is arranged, and production efficiency is lower.
2. a strand rail is separately fixed at independently on the elastic short rail sleeper about, track stability is very high to the degree of dependence of construction quality, if fail to guarantee the closely connected property between short sleeper and " gumshoe " or " gumshoe " and the railway roadbed in the construction, then elastic short rail sleeper becomes flexible easily, and track stability is poor.
3. the short sleeper of traditional elastic all wraps up because of the bottom of adopting " gumshoe " will lack sleeper reaches all around, the detection and the replacing that are positioned at the resilient sleeper-bearing of sleeper bottom need whole short sleeper is all lifted and can realize, difficulty is very big, does not still have the experience and the precedent of this respect in the actual operation.
The short sleeper of traditional elastic because of about the down short sleeper of strand rail is independent respectively is provided with, when train passes through, there is bigger dynamic sinking in rail with respect to orbit centre road bed surface, so can't be used for linear induction motor system, can not satisfy the special requirement of conductor rail installation, the integrated installation of tablet and use.
(3) utility model content
The purpose of this utility model provides the long sleeper of a kind of steel wheel rail traffic system elasticity, by left and right sides rail being arranged on the same long sleeper, backing plate and elastomeric isolation cover only are set in the end of sleeper, elastomeric isolation cover adopts thermoplastic elastomer (s), solve that the conventional rails measure is poor every the weak effect of making an uproar, track stability, backing plate and elastomeric isolation cover detect and change difficulty, can't be used for the technical problem of linear induction motor system.
For achieving the above object, the utility model adopts following technical scheme:
The long sleeper of this steel wheel rail traffic system elasticity, comprise sleeper member and the elastomeric isolation cover that is enclosed within sleeper member two ends, the right and left of sleeper member is respectively equipped with a pair of fastener fixing hole that is used for fixing a left side strand rail and right strand rail, it is characterized in that: above-mentioned elastomeric isolation cover is for Kei-shaped, it wraps in the bottom surface and the side at sleeper member two ends, be lined with resilient sleeper-bearing between elastomeric isolation cover and the sleeper member, vertical fitting tightly between sleeper member, resilient sleeper-bearing and elastomeric isolation cover three, the peripheral edge of elastomeric isolation cover and sleeper member are fitted and are sealed.The material of above-mentioned elastomeric isolation cover and U-shaped elasticity lengthening cover can be thermoplastic elastomer (TPE) or thermoplastic polyolefin elastomer.Above-mentioned sleeper member can be prestressed reinforced concrete tie member or ordinary reinforced concrete sleeper member.
Another technical scheme: the long sleeper of this king-size steel wheel rail traffic system elasticity, on the end of sleeper member, can be provided with the conductor rail installing hole, on the middle part of sleeper member, also can be provided with a pair of tablet installing hole that is used to install tablet.Above-mentioned elastomeric isolation cover near sleeper axis one end overlap with U-shaped elasticity lengthening cover, bonding or be connected by nested, the resilient sleeper-bearing pad is lined with the foamed plastics resilient sleeper-bearing in the bottom of U-shaped elasticity lengthening cover and elastomeric isolation cover below the sleeper end and between the elastomeric isolation cover.Above-mentioned resilient sleeper-bearing can be to dock with the foamed plastics resilient sleeper-bearing.Above-mentioned foamed plastics resilient sleeper-bearing can be full wafer shape or Openworks shape.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model with about a strand rail be fixed on the same long sleeper, backing plate and elastomeric isolation cover are set in the sleeper bottom surface, the elastomeric isolation cover adopts dustpan type or dustpan type and U type composite construction, the track stability that can effectively improve traditional elastic short rail sleeper existence is poor, resilient sleeper-bearing is changed defectives such as difficulty, be arranged on the same sleeper owing to left and right sides rail simultaneously, in the time of can effectively reducing train and pass through, the dynamic sinking of center lane bed surface is more suitable for adopting the track vehicle of linear induction motor system.In addition, the utility model can effectively reduce track vibration and reduce noise by the engineering practice proof, and does not increase construction cost.
The utility model can with about a strand rail be fixed on the same bolster, the elastomeric isolation cover adopts dustpan type structure, has eradicated the problem of the track stability difference that the more elastic short rail sleeper of domestic use exists, and has eliminated resilient sleeper-bearing and has changed defectives such as difficulty.
The utility model belongs to higher damper rail equipment, does doff impact damper system contrast test, the about 8.2～10.7dB of effectiveness in vibration suppression at scene, the real shop of engineering; Compare with common rail, every kilometer cost of single line only increases by 600,000 yuan, and Technological Economy is good.
In use, ordinary circumstance adopts standard type, and the external form of elastomeric isolation cover is Kei-shaped, by resilient sleeper-bearing and outsourcing elastomeric isolation cover (i.e. " gumshoe ") the essential structure pattern as the long sleeper of elasticity is set in bottom, prestressed reinforced concrete tie two ends.Be used for adopting extended type when conductor rail is installed, the profile of elastomeric isolation cover is a U-shaped, and the long sleeper of elasticity is used for the lengthening end employing standard type of conductor rail installation and the composite construction pattern of two elastomeric isolation covers of lap jointing type splicing.King-size production need not to increase in addition mould, takes and has saved cost of production.The utility model can be widely used in the noise reduction vibration isolation of steel wheel rail traffic system, is particularly useful for adopting the Rail Transit System of linear induction motor system, can satisfy the special requirement of integrated installation of tablet and use.
