Abstract
The utility model relates to a damping and noise reducing expansion joint of a train rail. The utility model is characterized in that the butt joint of the rail adopts the mutual butt joint of an oblique surface to form the damping and noise reducing expansion joint of the butt joint of the corresponding oblique surface. The utility model has the advantages that the utility model ensures that a corresponding position is always arranged on the rail to be formed into a supporting point to a wheel hub to make a wheel stably bridge the rail when the wheel passes a joint position, the utility model avoids strong collision impact, the use of the utility model is an effective way to fundamentally solve the problems of vibration and noise generation in the process of train running, the utility model has an inestimable development prospect to substantially raise the running speed of a train, extend the service life of the wheel and a road bad, eliminate noise pollution and beautify an environment.
Description
This utility model relates to a kind of damping noise reduction shrinkage joint of train rail.
Adopt the cross section butt joint between the existing train rail, two one steel rails leave the shrinkage joint of ten millimeter when connecting, though this has solved the problem of expanding with heat and contract with cold that the violent temperature difference is brought, but bring rhythmic vibrations and metal impact noise also for the operation of train, the problems referred to above not only directly influence the raising of train running speed, return resident along the line and bring noise pollution, cause psychology uneasy and fidgety.
The purpose of this utility model provides a kind of damping noise reduction shrinkage joint, when it can make the wheel wheel through the rail stroke seam, corresponding site is arranged all the time as origin of force bogie wheel wheel on the rail, make wheel excessive gently, avoid and second rail between strong impact, be expected fundamentally to solve the adverse effect that strenuous vibration and noise bring.
The task of this utility model is finished in the following way: form the shrinkage joint by butt joint between the rail, track bond is changed into by the butt joint of existing two ends cross section adopts the inclined-plane to dock mutually, at butt joint shrinkage joint, the corresponding formation of joint inclined-plane, when guaranteeing the shrinkage joint distance, there is intersection at the outstanding position of both ends of the surface on the butt joint direction.
Using this utility model is the effective way that fundamentally solves strenuous vibration and noise, help improving the speed of service of train, alleviate the common shake problem that bridge causes, prolong maintenance roadbed duration and wheel wheel application life, give surrounding resident and peace and quiet of passenger, environment stably, this utility model applies to also can get very good effect on express highway roadbed
Fig. 1 is the vertical view of the damping noise reduction shrinkage joint shape and structure figure of rail inclined-plane joint.
Fig. 2 is the lateral view of the damping noise reduction shrinkage joint shape and structure figure of rail inclined-plane joint.
Further describe this utility model below in conjunction with accompanying drawing
Form damping noise reduction shrinkage joint 1 as butt joint shrinkage joint, Fig. 1 inclined-plane by 2 butt joints of rail inclined-plane, when guaranteeing the shrinkage joint distance, there is intersection at the oblique angle that two rails stretches out on the butt joint direction, when making the wheel wheel through the shrinkage joint, prolong wheel running length and the time of wheel on seam relatively, overcome the shortcoming that wheel wheel curved surface direct " falling " enters the shrinkage joint, reach the effect of damping noise reduction, guarantee that whole seam crossing rail has corresponding site that the wheel wheel is formed supporting-point all the time, allows and takes turns the wheel smooth transition
Guarantee more than 45 ° below 90 ° at the angle of bevel that two inclined-plane joints stretch out.
Claims (2)
1, a kind of damping noise reduction shrinkage joint is formed by butt joint between the rail, it is characterized in that: interface adopts the inclined-plane to dock mutually between the rail, at butt joint shrinkage joint, the corresponding formation of joint inclined-plane, when guaranteeing the shrinkage joint distance, there is intersection at the outstanding position of both ends of the surface on the butt joint direction, make whole seam crossing on rail, have corresponding site that the wheel wheel is formed supporting-point all the time, allow and take turns the wheel smooth transition.
2, damping noise reduction according to claim 1 shrinkage joint is characterized in that the angle of bevel α that the inclined-plane joint stretches out guarantees more than 45.
