Abstract
The utility model belongs to the technical field of track traffics and provides an under-rail pad plate for a steel rail vibration reduction buckle element. The length of the front end and the back end of an under-rail pad plate (2) is greater than the length of an iron pad plate (4), the front end and the back end of the under-rail pad plate (2) are provided with downward right-angled bending elements (8), during installation, the downward right-angled bending elements (8) arranged at the front end and the back end of the under-rail pad plate (2) are clamped and buckled at the front end and the back end of the iron pad plate, the longitudinal positioning of the under-rail pad plate (2) on the iron pad plate (4) is realized, the left end and the right end of the under-rail pad plate (2) are respectively provided with position limiting blocks (1), and during the installation, the position limiting blocks (1) are in contact with the side wall of an elastic bar base (3) of the iron pad plate and realize the transverse positioning on the under-rail pad plate. The under-rail pad plate has the advantages that the occurrence of deviation phenomenon of the under-rail pad plate in the installation process is avoided, a rail gauge block (7) is prevented from being buckled and pressed on an under-rail pad plate (3), the deformation of an elastic bar is reduced, and the service life of the elastic bar is prolonged.
Description
Technical field
The utility model belongs to the track traffic technical field, mainly proposes a kind of railway rail pad of steel rail vibration damping fastener.
Background technology
Along with the development of Chinese national economy, the transportation industry of China has obtained development at full speed, particularly urban track traffic.In order to improve the effectiveness in vibration suppression of circuit, the laying of every circuit nearly all will relate to the steel rail vibration damping fastener, and the steel rail vibration damping fastener mainly comprises iron chair, spring base, spring, track gauge block, rail underlay; Damping fastening is fixed in sleeper through fastening system with fastener, limits the mobile of rail and plays damping effect; It is one-body molded with iron chair or connect one to be positioned at spring base on the iron chair; Between rail and iron chair, has railway rail pad; Railway rail pad also is the main damping means of most of Damping fastening; But shift phenomenon appears in railway rail pad easily that lay Damping fastening at present in installation process, cause track gauge block to be withheld to the rail underlay, has increased spring distortion in use, the life-span of having reduced spring.
Summary of the invention
For solving the problems of the technologies described above; The purpose of the utility model is the railway rail pad that proposes a kind of steel rail vibration damping fastener; Make that railway rail pad can be realized laterally when mounted, longitudinal register, avoid railway rail pad that shift phenomenon takes place in installation process, guarantee that track gauge block is not withheld to railway rail pad; Reduce the distortion of spring, improve the application life of spring.
The utility model adopts following technical scheme to realize its goal of the invention: a kind of railway rail pad of steel rail vibration damping fastener; The length of described railway rail pad rear and front end is greater than the length of iron chair; The rear and front end of railway rail pad has downward right angle bending; The downward right angle bending of railway rail pad rear and front end is buckled in the rear and front end of iron chair during installation, realizes the longitudinal register of railway rail pad on iron chair; The right ends of said railway rail pad all have when installing contact with the spring base side wall of iron chair, to the limited block of railway rail pad located lateral.
The railway rail pad of a kind of steel rail vibration damping fastener that the utility model proposes; Make that railway rail pad can be realized laterally when mounted, longitudinal register; Avoid railway rail pad that shift phenomenon takes place in installation process; Guarantee that track gauge block is not withheld to railway rail pad, reduce the distortion of spring, improve the application life of spring.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the user mode sketch map of the utility model.
Among the figure: 1, limited block, 2, railway rail pad, 3, the spring base, 4, iron chair, 5, track gauge block, 6, spring, 7, rail, 8, the right angle bending.
The specific embodiment
In conjunction with accompanying drawing and specific embodiment the utility model is explained:
As shown in Figure 1; A kind of railway rail pad of steel rail vibration damping fastener; The length of described railway rail pad 2 rear and front ends is greater than the length of iron chair 4; The rear and front end of railway rail pad 2 has downward right angle bending 8, and the downward right angle bending 8 of railway rail pad rear and front end is buckled in the rear and front end of iron chair 4 during installation, realizes the longitudinal register of railway rail pad 2 on iron chair 4; The right ends of said railway rail pad all have when installing contact with the spring base side wall of iron chair, to the limited block 1 of railway rail pad located lateral.The upper surface of the limited block 1 that said railway rail pad 2 right ends are had is lower than the upper surface of railway rail pad 2.Described fore-and-aft direction, vertically be the laying direction of rail.Described railway rail pad 2 can be thermoplastic elastic body, can have a plurality of convexities or groove at the upper and lower surfaces of railway rail pad 2.
With reference to Fig. 2, when the steel rail vibration damping fastener was installed, described railway rail pad 2 was arranged between iron chair 4 and the rail 7, and between two spring bases 3 on the iron chair 4; Downward right angle, railway rail pad 2 rear and front ends bends 8, is buckled in the rear and front end of iron chair 4, realizes the longitudinal register of railway rail pad 2 on iron chair 4; The limited block 1 of railway rail pad right ends contacts with the spring base side wall of iron chair, to the railway rail pad located lateral.One end of spring 6 is connected on the spring base 3, and the other end is withheld on rail 7 through track gauge block 5.
Claims (1)
1. the railway rail pad of a steel rail vibration damping fastener; It is characterized in that: the length of described railway rail pad (2) rear and front end is greater than the length of iron chair (4); The rear and front end of railway rail pad (2) has downward right angle bending (8), the right ends of said railway rail pad (2) all have when installing contact with spring base (3) sidewall of iron chair, to the limited block (1) of railway rail pad located lateral.
