Abstract
The utility model provides a concrete sleeper fastener system which is mounted in a sleeper bearing groove of a concrete sleeper. The concrete sleeper fastener system comprises a nylon rubber gasket, an iron washer located on the nylon rubber gasket, a baffle located on the iron washer, an elastic strip buckling the baffle and a bolt connected with the concrete sleeper. According to the concrete sleeper fastener system, the nylon rubber gasket and the iron washer are added, so that the sleeper bearing groove surface of the concrete sleeper can be effectively protected from being abraded; and stress of a sleeper stop shoulder is greatly improved by a lateral gasket arranged on the nylon rubber gasket and a lateral plate arranged on the iron washer.
Description
[technical field]
The utility model relates to the mixed earth sleeper fastening system of using on rail track, relates in particular to the mixed earth sleeper fastening system used on sharp radius curve rail track of being applicable to.
[background technology]
In the last few years, railway maintenance worker attempted mixed earth sleeper to be generalized to sharp radius curve track, and also to have sticked at a lot of useful work, but in use find to have occurred following harm at the plain concrete speciment sleeper of sharp radius curve:
1, the conquassation of sleeper rail support groove is because inside or outside of curve side rail all exists excessive conquassation under the effect of wheel, causes the rail rail support groove surface of directly wearing and tearing, and causes that rail turns up, widening of gauge, is forced to descend in advance road.
2, the breakage of sleeper shoulder block is because rail outside sharp radius curve is under the effect of wheel-rail lateral force, and shoulder block breakage reaches 52% outside sleeper, can not guarantee the frame strength of track.
Therefore, now, be badly in need of improving the problem of the conquassation of sleeper rail support groove and the breakage of sleeper shoulder block, need a kind of concrete sleeper fastener system of long service life.
[utility model content]
The technical problem that the utility model need solve is to provide a kind of shoulder block of avoiding sleeper and rail support groove is damaged, the concrete sleeper fastener system of long service life.
For solving above-mentioned technical problem, designed a kind of concrete sleeper fastener system, be installed in the rail support groove of concrete sleeper, described concrete sleeper fastener system comprises nylon rubber cushion, be positioned at iron chair on nylon rubber cushion, be positioned at baffle plate on iron chair, fasten the spring and the bolt being connected with concrete sleeper of baffle plate.
As the utility model, further improve, described nylon rubber cushion comprises in abutting connection with the heelpiece of rail support groove bottom with in abutting connection with the side pad of concrete sleeper shoulder block.
As the utility model, further improve, described iron chair comprises base plate, the adjacency side plate of described side pad and the apron block of supporting baffle being positioned in abutting connection with described heelpiece.
The utility model concrete sleeper fastener system has increased nylon rubber cushion and iron chair, can effectively protect concrete sleeper support rail groove face, avoids being worn; The side plate that the side pad that nylon rubber cushion is provided with and iron chair are provided with has improved the stressed of sleeper shoulder block greatly.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model concrete sleeper fastener system.
[specific embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model concrete sleeper fastener system, is installed in the rail support groove 10 of concrete sleeper 1.The utility model concrete sleeper fastener system is for installing and fixing rail 2.
The utility model concrete sleeper fastener system comprises nylon rubber cushion 3, be positioned at iron chair 4 on nylon rubber cushion 3, be positioned at baffle plate 5 on iron chair, fasten the spring 6 of baffle plate and the bolt 7 being connected with concrete sleeper.
Both are positioned at the rail support groove 10 of sleeper 1 nylon rubber cushion 3 and iron chair 4, have isolated the wearing and tearing of rail to 10 of rail support grooves, can effectively protect rail support groove 10, have extended the application life of concrete sleeper.
More optimizedly, the utility model nylon rubber cushion 3 comprises in abutting connection with the heelpiece 30 of rail support groove bottom with in abutting connection with the side pad 31 of concrete sleeper shoulder block; Iron chair 4 comprise be positioned in abutting connection with the base plate 40 of described heelpiece, the apron block 42 of the side plate 41 of adjacent sides pad and supporting baffle 5.The nylon rubber cushion 3 of this structure design and iron chair 4 can effectively prevent the damage of the shoulder block 11 of concrete sleeper, because the side plate 41 that the side pad 31 that nylon rubber cushion is provided with and iron chair are provided with has improved the stressed of sleeper shoulder block 11 greatly.
The utility model concrete sleeper fastener system can be protected concrete sleeper support rail groove face effectively, avoids being worn; Greatly improved the stressed of sleeper shoulder block; Thereby extended the application life of sleeper.
Above-described is only embodiment of the present utility model; at this, it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make improvement, but these all belong to protection domain of the present utility model.
