Description
Technical field
This utility model belongs to railroad bridge technical field, and in particular to a kind of railroad bridge guard rail.
Background technology
In pipe, on masonry bridge bridge, the laying form of guard rail limits big machinery tamping car operation, using light track maintenance machinery
Tamping operation is carried out to circuit, the line maintenance of bridge location is of low quality, cause worker's workload big.If being made firm by ramming using large-scale
Car carries out tamping operation to circuit on bridge, must just dismount guard rail, and provisions shield maintaining unit increased workload, increased peace
Full hidden danger, has an effect on railway transportation.
Red building woods to the positive line length of the western special purpose railroad in Shenmu County is 42.56km, and east connects refreshing big line red building woods station, and west connects bag
The western station in western railway paths Shenmu County.Interior existing highway bridge 22 is managed, altogether 7767.84m, wherein 4 5161.14m of grand bridge, bridge
7 1831.19m, 11 775.51m of jackshaft, account for railway main track total length about 20%, in addition the construction of the red refreshing line of new projects, bridge
Beam length will increase to about 20 kilometers, and bridge location becomes " bottleneck " location for conserving circuit for big machinery.With coal
The increase year by year of freight volume, the destructiveness of circuit increase year by year, at least will arrange once large-scale smashing every year to these bricklaying bridges
Gu car operation, the guard rail dismounting workload on bridge are big, in disassembly process fastener be easily lost, well damage, according to statistics to line
When road adopts large-scale tamping car operation, dismount guard rail in pipe every year, supplement artificial, about 550,000 yuan of Master Cost needed for fastener.For
Guarantee circuit repair quality on bridge, improve large-scale tamping car working performance, reduces cost eliminates safe hidden trouble, study new-type
Guard rail paving mode is extremely important.
Utility model content
The purpose of this utility model is to provide a kind of railroad bridge guard rail, solves masonry bridge present in prior art
Beam dismounts guard rail high cost, there is potential safety hazard and inefficiency.
The technical scheme adopted by this utility model is that a kind of railroad bridge guard rail, including guard rail body, guard rail
Body is fixed on the sleeper between two rails being parallel to each other.
The characteristics of this utility model, also resides in,
Two sections of straight rails that guard rail body is included being fixed on end of the bridge and be connected in lambdoid curved rail and with curved rail two ends, two
Section straight rail is parallel to each other and vertical with sleeper.
Curved rail length is not less than 1.9m.
Two sections of straight rails are fixed on sleeper by screw spike, and the top of each screw spike is fixed by hex nut,
Double-layer spring packing ring is additionally provided between hex nut and screw spike, is additionally provided between double-layer spring packing ring and screw spike
Buckle gauge adjustment circle.
The a diameter of Ф 24mm of screw spike.
The beneficial effects of the utility model are that a kind of railroad bridge guard rail, by connecting two sections at the curved rail two ends of end of the bridge
Straight rail, two sections of straight rails are parallel to each other and vertical with sleeper, arrange curved rail length and are not less than 1.9m, and straight rail is solid by screw spike
On sleeper, the top of each screw spike is fixed by hex nut, is additionally provided between hex nut and screw spike
Double-layer spring packing ring, it is ensured that the sleeper after drilling in the concrete pillow top is not in porous dehiscence in the presence of train load, and
Ensure that off-line trailing wheel, to rolling and sleeper head between in main guard rail spacing, will not cause train overturning.
Description of the drawings
Fig. 1 is a kind of scheme of installation of the railroad bridge guard rail of this utility model on railway；
Fig. 2 is a kind of structural representation of railroad bridge guard rail of this utility model.
In figure, 1. guard rail body, 2. screw spike, 3. double-layer spring packing ring, 4. buckle gauge adjustment circle, 5. hexagonal spiral shell
Mother, 6. rail, 7. sleeper, 8. curved rail, 9. straight rail.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail.
A kind of railroad bridge guard rail of this utility model, structure is as shown in figure 1, including guard rail body 1, guard rail body
1 is fixed on the sleeper 7 between two rails 6 being parallel to each other, and guard rail body 1 includes being fixed on end of the bridge in lambdoid
Curved rail 8 and two sections of straight rails 9 being connected with 8 two ends of curved rail, two sections of straight rails 9 are parallel to each other and vertical with sleeper 7, and curved rail 8 is grown
Degree is not less than 1.9m, as shown in Fig. 2 two sections of straight rails 9 are fixed on sleeper 7 by screw spike 2, the top of each screw spike 2
Portion is fixed by hex nut 5, is additionally provided with double-layer spring packing ring 3, double-layer spring pad between hex nut 5 and screw spike 2
Buckle gauge adjustment circle 4 is additionally provided between circle 3 and screw spike 2, wherein, 2 a diameter of Ф 24mm of screw spike.
A kind of railroad bridge guard rail of this utility model, reduces maintenance of way cost, improves the work of large-scale tamping car
Industry efficiency and line maintenance quality, and greatly reduce the labor operation intensity of rail man, eliminate the peace of operation on bridge
Full hidden danger.Meanwhile, this utility model successfully solves puzzlement of the large-scale tamping machine in the operation of bridge location.In addition, using upper
Guard rail modification scheme is stated, guard rail can not recover in time and cause on bridge without guard rail during it also avoid because of large-scale tamping car operation
Phenomenon, makes traffic safety have guarantee.
