Abstract
The utility model belongs to the technical field of track traffic and provides a backing plate under a rail, which is characterized in that the backing plate under a rail (3) comprises grooves(2). The grooves (2) are matched with the boss (4) of an iron backing plate (6), so that the backing plate under a rail is laterally and longitudinally positioned. The backing plate under a rail (3) comprises two grooves (2) and the two grooves (2) are respectively positioned at the front and rear ends of the backing plate under a rail (3). The offsetting phenomenon of the backing plate under a rail during the installation process is prevented and a gauge block (7) is prevented from pressing onto the backing plate under a rail (3). The deformation of an elastic strip (8) is reduced, so that the service life of the elastic strip is prolonged.
Description
Technical field
The utility model belongs to the track traffic technical field, mainly proposes a kind of railway rail pad.
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 to propose a kind of railway rail pad; Railway rail pad, iron chair are cooperatively interacted realize railway rail pad laterally, 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.
A kind of railway rail pad, described railway rail pad have in order to iron chair on boss cooperate realize railway rail pad laterally, the groove of longitudinal register; The groove that said railway rail pad had is two, lays respectively at the rear and front end of railway rail pad.
The right ends of railway rail pad have when installing contact with the spring base side wall, to the limited block of railway rail pad located lateral.
A kind of railway rail pad that the utility model proposes; The detent that railway rail pad is had cooperates horizontal, the longitudinal register of realizing railway rail pad with iron chair; 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 limited block that the railway rail pad right ends is had contacts with the spring base side wall during installation, makes the located lateral of railway rail pad more reliable.

Among the figure: 1, limited block, 2, groove, 3, railway rail pad, 4, boss, 5, the spring base, 6, iron chair, 7, track gauge block, 8, spring, 9, rail.
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; Described railway rail pad 3 can be thermoplastic elastic body; Upper and lower surfaces at railway rail pad 3 can have a plurality of convexities or groove, the railway rail pad rear and front end have respectively in order to iron chair 6 on boss cooperate realize railway rail pad laterally, the groove 2 of longitudinal register; Described fore-and-aft direction, vertically be the laying direction of rail.As shown in Figure 2, when the steel rail vibration damping fastener was installed, iron chair 6 was positioned at the bottom of rail 9, and railway rail pad 3 is arranged between rail 9 and the iron chair 6; Has boss 4 in the rear and front end of iron chair 6; The groove 2 that railway rail pad 3 rear and front ends are had is buckled on the boss of iron chair 6, cooperate with boss on the iron chair 6 realize railway rail pad laterally, longitudinal register; The width of railway rail pad 3 is less than the width of rail base plate, can realize maximum gauge regulated quantity, and guarantees that track gauge block 7 do not withheld to railway rail pad by spring 8.On iron chair 6, have two spring bases 5, described two spring bases 5 be positioned on the diagonal of iron chair or two spring datum axles to being symmetricly set on the iron chair 6; One end of spring 8 is connected on the spring base 5, and the other end is withheld on rail 9 through track gauge block 7.
Fig. 3 provides the structural representation of the utility model embodiment 2, among this embodiment, railway rail pad 3 rear and front ends have respectively in order to iron chair 6 on boss cooperate realize railway rail pad laterally, the groove 2 of longitudinal register; Have when installing in the right ends of railway rail pad 3 contact with the spring base side wall, to the limited block 1 of railway rail pad located lateral.In conjunction with Fig. 4, the upper surface of the limited block 1 that said railway rail pad 3 right ends are had is lower than the upper surface of railway rail pad 3.
As shown in Figure 5, when the steel rail vibration damping fastener was installed, iron chair 6 was positioned at rail base plate bottom, and railway rail pad 3 is arranged between rail base plate and the iron chair 6; The groove 2 that the railway rail pad rear and front end is had is buckled on the boss of iron chair 6, cooperate with boss on the iron chair 6 realize railway rail pad laterally, longitudinal register; The width of railway rail pad 3 is less than the width of rail base plate, can realize maximum gauge regulated quantity, and guarantees that track gauge block 7 do not withheld to railway rail pad by spring 8.The limited block 1 of railway rail pad 3 right ends contacts with the spring base side wall, to the railway rail pad located lateral.Because the upper surface of limited block 1 is lower than the upper surface of railway rail pad 3, has certain clearance between the limited block 1 of track gauge block 7 and railway rail pad when making installation.
