Abstract
The utility model discloses a single crossover for urban rail transit, which comprises two groups of single-open railroad turnouts. Each single-open railroad turnout comprises a railroad switch, a frog, a guardrail and a connecting part, wherein an insulating joint is arranged at the heel end of the frog; the connecting part comprises sleepers and fasteners; the sleepers and the fasteners are arranged behind the insulating joint; and the sleepers are fixedly connected with the fasteners through anchor bolts. The utility model has the benefits as follows: as the insulating joints and insulating offset buckle plates, which meet the insulating requirements of track circuits, are arranged at the heel ends of the frogs, a dead zone is avoided, so as to ensure that a train can pass through straightly and shunt with safety; and the single crossover for urban rail transit is suitable for railroad sections wherein the distance between middle lines is 3.4 m.
Description
Technical field
The utility model relates to a kind of single branch-cut bridge; Particularly relate to a kind of urban track traffic with No. 9 track switch 3.4m of 60kg/m rail distance between centers of tracks list branch-cut bridge.
Background technology
Single branch-cut bridge is that train runs to the path of being passed by between the parallel adjacent lines by a circuit, can realize that train changes line and turns back, and single branch-cut bridge requires to be provided with according to the city track traffic engineering operation.
In the urban rail transit in China engineering, according to code requirement, the distance between centers of tracks of the single branch-cut bridge setting of No. 9 track switches of 60kg/m rail is 4.2m or more than the 4.2m, condition is 4.0m at need.But in practice of construction, receive the restriction of geographical environment, often can not satisfy construction requirement; Just laid No. 9 track switch 3.6m of one group of 60kg/m rail distance between centers of tracks list branch-cut bridge like No. 5 lines of Beijing Metro; But also have some rugged environments more, can't realize the insulating joint that relates to when particularly distance between centers of tracks is for 3.4m when being 3.4m according to above designing requirement like distance between centers of tracks; The fastener of insulation position, and the sleeper behind the rut is all different with the needed technical requirements of the distance between centers of tracks of present use.
Summary of the invention
The utility model technical problem to be solved is that No. 9 track switch 3.4m of a kind of 60kg/m rail distance between centers of tracks list branch-cut bridge is provided.
The technical scheme that the utility model adopted is: single branch-cut bridge is used in a kind of urban track traffic, comprises two groups of simple turnouts; Said simple turnout comprises, railway switch, railway frog, guard rail and coupling part; Heel end at said railway frog is equipped with insulating joint; Said coupling part comprises sleeper and the fastener behind the insulating joint, and said sleeper is fixedly connected through anchor bolt with fastener.
Said sleeper includes first sleeper, second sleeper and the 3rd sleeper; First rail, second rail and two fasteners are installed on said first sleeper, and said fastener is installed in the outside of first rail and second rail respectively, is installed with insulation offset distance buckle in the inboard of said first rail and second rail.
First rail and second rail and three fasteners are installed on said second sleeper, and said two fasteners are installed in the both sides of first rail; The installed inside of second rail has a fastener, and second rail outside is equipped with guard rail, and said guard rail, fagging and insulation offset plate are installed on the platen, and said insulation sleeve passes guard rail and insulation offset plate and fagging rivet clasp.
Be embedded with nylon sleeve on said second sleeper and the 3rd sleeper, said nylon sleeve is corresponding with the position of fastener anchor bolt.
The beneficial effect of the utility model is: satisfy the insulating joint and insulation offset distance buckle that insulation of track circuit requires owing to the heel end at railway frog is equipped with; Avoided the generation in " between the dead band "; Guarantee that train directly to passing through and changeing the line safe operation, is applicable to that distance between centers of tracks is the location of 3.4m in the urban track traffic.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
Shown in Fig. 1 to Fig. 7 b, the utility model urban track traffic uses single branch-cut bridge to be applicable to that distance between centers of tracks comprises as the location of 3.4m in the urban track traffic, two groups of simple turnouts; Said simple turnout comprises, railway switch, railway frog, guard rail and coupling part; Be equipped with at the heel end of two simple turnout railway frogs and satisfy the insulating joint 10 that insulation of track circuit requires, insulating joint 10 has been avoided the generation in " between the dead band ", guarantee train directly to through and change the line operation; Said coupling part comprises sleeper and the fastener behind the insulating joint, and said sleeper is fixedly connected through anchor bolt with fastener; Fastener mainly is made up of electro-insulating rubber backing plate, iron chair and the iron seat 1 installed in regular turn, and said sleeper includes first sleeper 20, second sleeper 30 and the 3rd sleeper 40, and said second sleeper 30 and the 3rd sleeper 40 are all selected short sleeper for use; First rail 60, second rail 70 and two iron seats 1 are installed on said first sleeper; Said fastener is installed in the outside of first rail 60 and second rail 70 respectively; After first sleeper behind the solid manganese steel frog heel end and the second sleeper place fastener are installed; Also must satisfy the track insulation requirement, therefore, be installed with insulation offset distance buckle 2 in the inboard of said first rail 60 and second rail 70.Second sleeper behind the solid manganese steel frog heel end and the 3rd sleeper; Because narrow space; Need to carry rail and a guard rail of two different directions, therefore this place's sleeper design that will extend is in order to satisfy the anchor bolt position of iron chair; First rail 60 and second rail 70 and three iron seats are installed on said second sleeper 30, and said two fasteners are installed in the both sides of first rail 60; The installed inside of second rail 70 has an iron seat; Second rail, 70 outsides are equipped with guard rail 50; Said guard rail 50, fagging 4 and insulation offset plate 5 are installed on the platen 3; Said insulation sleeve 6 passes guard rail 50 and insulation offset plate 5 and fagging 4 rivet clasps, isolates electric through insulation offset plate and insulation sleeve between guard rail and fagging and the platen.Be embedded with nylon sleeve 7 on said second sleeper 30 and the 3rd sleeper 40, said nylon sleeve 7 is corresponding with the position of fastener anchor bolt.Basis is novel to satisfy the insulating joint and insulation offset distance buckle that insulation of track circuit requires owing to the heel end at railway frog is equipped with; Avoided the generation in " between the dead band "; Guarantee that train directly to passing through and changeing the line safe operation, is applicable to that distance between centers of tracks is the location of 3.4m in the urban track traffic.
