Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are clearly and completely described the technical scheme in the utility model embodiment below in conjunction with accompanying drawing.It should be noted that, below in Fig. 1, Fig. 2 a, Fig. 3, Fig. 4 and Fig. 5 a of mentioning, heightening the cross sectional side view under state for rail fastening on the left of dotted line, is the lateral view of rail fastening under uncomfortable high state on the right side of dotted line.
Present embodiments provide a kind of rail fastening, this rail fastening is applied to non-fragment orbit to be had in shoulder arrangement, as shown in Figure 4, this rail fastening comprises gauge apron 12 and punching press iron chair 6b, wherein gauge apron 12 comprises the first abutment end and the second abutment end, first abutment end abuts with concrete shoulder block 14, and the second abutment end abuts with rail 100; Punching press iron chair 6b is arranged at the below of gauge apron 12.
Owing to the Insulation rail distance keeper 3 in original rail fastening and gauge apron 4 to be replaced by the gauge apron 12 with two abutment ends, first abutment end of this gauge apron 12 abuts with concrete shoulder block 14, second abutment end abuts with rail 100, therefore the transfer mode of rail lateral force becomes: rail 100 → gauge apron 12 → concrete shoulder block 14, without the need to passing through, the transmission that bulge-structure carries out lateral force is set on iron chair, thus iron chair can be set to slabbed construction, the iron chair of slabbed construction adopts lower-cost Sheet Metal Forming Technology to be formed, therefore casting iron chair 6a higher for original cost can be replaced by lower-cost punching press iron chair 6b in the present embodiment, reduce the manufacturing cost of rail fastening.
In the present embodiment, the punching press iron chair 6b that rail fastening adopts act as reduce train by time rail 100 the amount of tumbling, improve train operation time stationarity.As shown in figure 5 a and 5b, the structure of punching press iron chair 6b is slabbed construction, by there is no bulge-structure thereon, therefore without using die casting and molding manufacture, only need to adopt Sheet Metal Forming Technology manufacture, compared to the Design and manufacture of cast shaping process and mould thereof, adopt Sheet Metal Forming Technology to make punching press iron chair 6b technique simple, and die cost is low, the cost of the punching press iron chair 6b therefore adopted in the present embodiment is lower than the casting iron chair 6a adopted in original rail fastening.
Based on technique scheme, the apron block 13b that also can arrange between the first abutment end of gauge apron 12 and concrete shoulder block 14 in the present embodiment, the relative two sides of apron block 13b offset with the first abutment end of gauge apron 12 and concrete shoulder block 14 respectively, and apron block 13b is for improving the stability of gauge apron 12.By changing gauge apron 12 and the apron block 13b of different model, the adjustment to rail lateral attitude can be realized.After arranging apron block 13b, under the state that rail fastening is not heightened, the transfer mode of rail 100 lateral force becomes: rail 100 → gauge apron 12 → apron block 13b → concrete shoulder block 14.
Under the state that rail fastening is heightened, the bottom of apron block 13b does not contact with the concrete foundation below rail fastening, and for strengthening the stability of apron block 13b, the rest pad 15 that can arrange below apron block 13b, with supporting baffle seat 13b.
The rail fastening that the present embodiment provides also can comprise screw spike 1, spring 2a and resilient sleeper-bearing 7, and wherein spring 2a is arranged at the top of gauge apron 12, and resilient sleeper-bearing 7 is arranged at the below of punching press iron chair 6b.Spring 2a, gauge apron 12, punching press iron chair 6b and resilient sleeper-bearing 7 all have through hole, and screw spike 1 is successively through the through hole on spring 2a, gauge apron 12, punching press iron chair 6b and resilient sleeper-bearing 7.Can arrange service sleeve 8 in concrete foundation below rail fastening, screw spike 1 is fixedly connected with service sleeve 8, thus reaches the effect of fixing spring 2a, gauge apron 12, punching press iron chair 6b and resilient sleeper-bearing 7.
Above-described resilient sleeper-bearing 7 for improving track elasticity for rail 100, to improve comfortableness during train operation.
Between punching press iron chair 6b and rail 100, also can arrange rubber mat plate 5a, this rubber mat plate 5a is used for reducing the percussion that liquidates between foundary weight backing plate 6b of rail 100.
When needs are heightened rail 100, can arrange between rubber mat plate 5a and punching press iron chair 6b and heighten pad, or height adjusting cushion plate 11b is set below resilient sleeper-bearing 7, or two kinds of modes are combined, wherein heighten the magnitude setting of pad and the magnitude setting of thickness and height adjusting cushion plate 11b and thickness all can design according to actual needs, thus the Height Adjustment amplitude of rail 100 can be made to reach-4mm ~+26mm.
It should be noted that, arrange height adjusting cushion plate 11b below resilient sleeper-bearing 7 after, the transfer mode of rail 100 lateral force becomes: rail 100 → gauge apron 12 → apron block 13b → height adjusting cushion plate 11b → concrete shoulder block 14.
As shown in Figure 3, if the simple rubber mat plate 5b that relies on provides track elasticity, once the elasticity of rubber mat plate 5b is excessive, when certainly will rail 100 will be caused stressed, rubber mat plate 5b is out of shape excessive, and excessive deflection can increase the tired amplitude of spring 2b, greatly reduces the fatigue life of spring 2b; Moreover the excessive deformation of rubber mat plate 5b also can affect the lateral stability of rail 100, when causing rail 100 stressed, the amount of tumbling is excessive, affects traffic safety.In the present embodiment, track elasticity is provided by utilizing resilient sleeper-bearing 7, punching press iron chair 6b is utilized to reduce the track amount of tumbling, utilize rubber mat plate 5a to reduce the impact forces between rail 100 and punching press iron chair 6b simultaneously, thus both ensure that larger track elasticity, again reduce rail 100 stressed time the amount of tumbling.
The present embodiment additionally provides a kind of rail fastener system, and this rail fastener system comprises concrete shoulder block 14 and is arranged at the rail fastening of concrete shoulder block 14 side, and this rail fastening is the rail fastening described in above-mentioned each technical scheme.Because the cost of the rail fastening described in above-mentioned each technical scheme is lower, the cost therefore comprising the rail fastener system of this rail fastening is also lower.
In above-mentioned rail fastener system, included angle A between concrete shoulder block 14 and the bearing surface (upper surface of the concrete foundation namely below rail fastening) of supporting rail fastener can be set to 110 °, to ensure the good lateral bearing stability of rail 100.
In addition, by adding high concrete shoulder block 14, the lateral bearing stability of rail 100 is improved.
The foregoing is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
