Abstract
The utility model discloses a spring bar (Type III) fastener high-strength composite insulating rail gauge block, comprising an insulation block. Knob insulators are put through the two stress sides at the stress location of the insulation block. Through composite reinforcement of the insulation rail gauge block by the knob insulators, the wheeltrack force on the insulation rail gauge block and the attaching force of the spring bar are effectively decomposed, the wear-resistance performance and service life of the insulation rail gauge block are improved, and the safety of the insulation rail gauge block is enhanced. The utility model is applicable to fasteners for connecting the steel rails and the sleepers of railway.
Description
Technical field
The utility model relates to a kind of railroad track accessory, especially a kind of spring III type fastener high-strength compound Insulation rail distance keeper.
Background technology
The elastic bar fastener Insulation rail distance keeper is a kind of fastener that rail and sleeper are linked together, and generally makes with the glass fiber enhanced nylon 66 engineering plastics.In actual use, the pressure that this track gauge block is subjected to rail and elastic bar fastener is bigger, because the compressive strength and the flexural strength of track gauge block itself are not enough, so be subject to lateral deflection clothes or rupture, perk, bending, cause the application life of track gauge block lower, unconventional property disrepair phenomenon is especially serious on the sharp radius curve road.
In order to change this situation, the patent No. is ZL02213894.3, the utility model that name is called " improved railroad track with the reinforced Insulation rail distance keeper of spring bar III type fastener " discloses a kind of improvement project, its scheme is that the contact surface at track gauge block and elastic bar fastener and rail is provided with steel disc, thereby improves the local compressive strength of track gauge block in the force part.But there is following shortcoming in this scheme: the first, because steel disc only is arranged on the one side of track gauge block force part, fracture by fatigue, flexural deformation still take place in the another side of no steel disc after stressed; The second, the thinner thickness of steel disc, and be the surface of being fixed in track gauge block, the long-term back steel disc that uses comes off easily, turns over and stick up.Three, because of track gauge block is installed in the rail both sides, when the ight soil of toilet train, effluent discharge, be punched on the track gauge block, cause on the track gauge block steel disc because of corrosion failure, and cause the track gauge block insulaion resistance to descend.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing Insulation rail distance keeper exists, and a kind of intensity height is provided, spring III type fastener high-strength compound Insulation rail distance keeper firm, long service life is installed.
The technical solution of the utility model is: spring III type fastener Insulation rail distance keeper is carried out compound enhancing, it is characterized in that: the incline force part that leans the flange of rail at described Insulation rail distance keeper body is provided with the porcelain knob that runs through the stress surface both sides with the spring force part of withholding the flange of rail.Be provided with the porcelain knob that runs through the stress surface both sides as the incline force part that leans the flange of rail at the insulation block, or/and be provided with the porcelain knob that runs through the stress surface both sides in the spring force part that the insulation block is withheld the flange of rail.
The cross sectional shape of porcelain knob can be multiple geometry, as circular or polygon.The porcelain knob material is an aluminium oxide ceramics, and also available other can satisfy the material of technical datas such as intensity and insulaion resistance.
The utility model compared with prior art, its advantage is: 1, crushing resistance and resistance to impact significantly strengthen.
Because the porcelain knob in the utility model has very good compressive property, can bear bigger pressure when track gauge block is stressed, thereby has improved the compressive strength of track gauge block greatly.By adopting porcelain knob that Insulation rail distance keeper is carried out compound enhancing, effectively decomposed the wheel track power and the elastic-strip pressure that act on the Insulation rail distance keeper, improved the wear resistance and the application life of Insulation rail distance keeper, guarantee the safe handling of Insulation rail distance keeper.The check of product quality supervision and inspection center shows through the Ministry of Railways, every test ratings such as compressed residual distortion of the present utility model, hardness, insulaion resistance, impact property, cutting performance, fatigue test are all above Ministry of Railways's standard, wherein the check data of fatigue test load cycle-index is more than 4,000,000 times, the standard 2,000,000 times that not only is higher than the Ministry of Railways far away, also be higher than 2,600,000 times of existing product, significantly improved application life.2, the utility model adopts porcelain knob is embedded in the track gauge block, and runs through the stress surface both sides, and this mounting means is very firm, avoids the long-term back porcelain knob that uses to come off.3, the porcelain knob in the utility model has good corrosion resistance, can in use not lose efficacy because of polluting corrosion, also can not cause the decline of track gauge block insulaion resistance.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, 2, spring III type fastener high-strength compound Insulation rail distance keeper comprises insulation block 1.Lean the incline position 3 of the flange of rail at Insulation rail distance keeper, the porcelain knob 2 of 5 ￠ 6mm is set, decomposed the wheel track power that acts on the track gauge block.At the spring pressurized position 4 that Insulation rail distance keeper is withheld the flange of rail, the porcelain knob 2 of 2 ￠ 6mm is set, decomposed the elastic-strip pressure that acts on the track gauge block.The material selection A99% aluminium oxide ceramics of porcelain knob, its important technological parameters is: density is 3.85g/cm
3, flexural strength is 350Mpa, and compressive strength is 3600Mpa, and impact strength is 5.0Mpam
1/2, Vickers hardness is 1900HV0.5,20 ℃ of volume resistances are 〉=10
14Ω.
Fig. 3 illustrates the user mode figure of Insulation rail distance keeper, rail 5 places on the sleeper 7 by rubber mat plate 6, Insulation rail distance keeper 1 relies at the bottom of the pillow of rail 5, one end of spring 8 is fixed in the preburied iron base 9 of sleeper 7, the other end is withheld in the end face of Insulation rail distance keeper 1, and nationality is to be fixed in rail 5 on the sleeper 7.
