The assembly structure schematic diagram of the turnout switch that Fig. 3 provides for a kind of detailed description of the invention of the utility model.
Detailed description of the invention
Core of the present utility model is to provide a kind of turnout switch, and the structure of this turnout switch is comparatively solid and reliable, and its maintenance workload is lower.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 3, the assembly structure schematic diagram of the turnout switch that Fig. 3 provides for a kind of detailed description of the invention of the utility model.
In a specific embodiment, turnout switch provided by the utility model, comprise two pieces of connection backing plates 4 be fixed in the horizontal direction on sleeper 13, the bearing of trend of connection backing plate 4 is consistent with the bearing of trend of sleeper 13, two connection backing plates 4 are respectively arranged with the stock rail 8 be parallel to each other, be fastened by fastening assembly between the inner end two connection backing plates 4 being also respectively arranged with tongue 6, two connection backing plate 4 be parallel to each other; The outer end of connection backing plate 4 is fixed with the rail brace 12 matched with stock rail 8, the outside portion of rail brace 12 has the reinforcing rib matched with connection backing plate 4, be disposed with web of the rail backing plate 9 and common backing plate 10 along the bearing of trend from-inner-to-outer of sleeper 13 between the medial surface of rail brace 12 and stock rail 8, fixed by the first securing member 11 between stock rail 8, web of the rail backing plate 9, common backing plate 10 and rail brace 12.
By installing connection backing plate 4 additional on sleeper 13, and the assembly structure rail body assemblies such as stock rail 8 and tongue 6 are layed on connection backing plate 4, increase effectively the lifting surface area of sleeper 13, thus the corresponding raising of overall track capacity that track switch is located, the gouging abrasion of the matable assemblies such as the low sliding table caused because tongue 6 when track switch is changed slides of a step-down of going forward side by side and distortion, reduce simultaneously effectively because of train by time structural impact that track switch place is caused and the track switch that causes is creeped and the phenomenon such as lateral displacement, in addition, rail brace 12 can provide enough structural support power for the outside of stock rail 8, avoid outside rail, moving the generation with phenomenons such as sleeper cuttings, thus improve overall construction intensity and the reliability thereof of turnout switch further, and make the corresponding minimizing of its maintenance workload, the corresponding reduction of maintenance cost.
Further, described fastening assembly comprises the bolt 3 running through two connection backing plates 4 successively, bolt 3 is arranged with the insulation sleeve 1 and insulating slab 2 that match with connection backing plate 4 respectively.Bolt 3 effectively can ensure assembly structure reliability between two connection backing plates 4 and rigging position stability relatively thereof, insulation sleeve 1 and insulating slab 2 effectively can avoid track circuit short circuit connectivity problem simultaneously, stable insulation is reliable, thus further ensures the operational reliability of turnout switch.
Particularly, the top of rail brace 12 is vertically lower than the top of stock rail 8.The support force outside rail brace 12 pairs of stock rails 8 slightly can be improved further lower than the fit structure on stock rail 8 top in this kind of rail brace 12 top, ensures structural reliability and the stability of stock rail 8, and makes the corresponding raising of the overall construction intensity of described turnout switch.
More specifically, rail brace 12 is fixedly welded on connection backing plate 4.The fastening reliability that this kind is welded and fixed structure is higher, and without the need to installing securing member additional, thus effectively ensure that the assembly reliability between rail brace 12 and connection backing plate 4 and structural integrity.
Certainly, above-mentioned rail brace 12 is fixedly welded on connection backing plate 4 and is only preferred version, and this rail brace 12 can also be fixed on connection backing plate 4 by securing members such as bolts, as long as that is, can meet the actual use needs of described point movement.
On the other hand, connection backing plate 4 is fixed on sleeper 13 by the second securing member 5.This second securing member 5 effectively can ensure the fastening strength between connection backing plate 4 and sleeper 13, thus makes the overall structure reliability of point movement be able to corresponding raising.
In addition, the second securing member 5 is screw spike.Should be understood that, in practical set use procedure, above-mentioned second securing member 5 is not limited to the screw spike shown in figure, and it can also be the securing member that fastening bolt etc. meets track fastening strength, that is, as long as the actual use needs of described point movement can be met.
In addition, the first securing member 11 is square toes stud.It should be pointed out that the first securing member 11 is only preferred version for square toes stud, it can also be the structural fasteners such as bolt, as long as that is, can meet the actual use needs of described turnout switch.
In summary, the turnout switch provided in the utility model, comprise two pieces of connection backing plates be fixed in the horizontal direction on sleeper, the bearing of trend of described connection backing plate is consistent with the bearing of trend of sleeper, connection backing plate described in two is respectively arranged with the stock rail be parallel to each other, connection backing plate described in two is also respectively arranged with the tongue be parallel to each other, is fastened by fastening assembly between the inner end of connection backing plate described in two; The outer end of described connection backing plate is fixed with the rail brace matched with described stock rail, the outside portion of described rail brace has the reinforcing rib matched with described connection backing plate, be disposed with web of the rail backing plate and common backing plate along the bearing of trend from-inner-to-outer of sleeper between the medial surface of described rail brace and described stock rail, fixed by the first securing member between described stock rail, described web of the rail backing plate, described common backing plate and described rail brace.By installing connection backing plate additional on sleeper, and the assembly structure rail body such as stock rail and tongue assembly is layed on described connection backing plate, increase effectively the lifting surface area of sleeper, thus the corresponding raising of overall track capacity that track switch is located, the gouging abrasion of the matable assemblies such as the low sliding table caused because tongue when track switch is changed slides of a step-down of going forward side by side and distortion, reduce simultaneously effectively because of train by time structural impact that track switch place is caused and the track switch that causes is creeped and the phenomenon such as lateral displacement, in addition, described rail brace can provide enough structural support power for the outside of stock rail, avoid outside rail, moving the generation with phenomenons such as sleeper cuttings, thus improve overall construction intensity and the reliability thereof of turnout switch further, and make the corresponding minimizing of its maintenance workload, the corresponding reduction of maintenance cost.
Above turnout switch provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
