Abstract
The utility model provides a simplify switch blade heel end structure for modern tram switch to effectively improve the frequent nevertheless maintenance and the changeover procedures of complicacy originally, realized quick dismouting and maintenance, effectively guaranteed the normal running of vehicle. Including the switch blade with lie in fender rail, the stock rail of its both sides respectively, set up smooth movable bed board, bottom plate under the switch blade. It welds as an organic wholely with smooth movable bed board, bottom plate to keep off the rail, switch blade working edge, inoperative limit one side sets up clamp plate, the buckle of withholding its formation respectively, this clamp plate with keep off rail, smooth movable bed board welding, this buckle passes through high strength bolt and can dismantle with smooth movable bed plate -type one -tenth and be connected.
Description
Technical field
The utility model relates to railroad track and urban track traffic, and particularly a kind of track switch for modern tram simplifies heel of switch rail structure.
Background technology
Point tongue is the vitals in railway switching machines, relies on pulling of tongue, train is introduced main track or side line direction.One end that tongue is connected with lead curve rail claims heel of switch rail.The heel end structure of tongue must ensure that tongue can require according to different turn-out tracks to swing in the plane, more stable and stronger again, manufactures simple, easy to maintenance.Being different from general railway switch and subway railroad switch, is meet mixed row traffic needs, and modern tram track switch has and adopts that flush type track structure, grooved rail, vehicle axle weight are low, the more high distinguishing feature of track switch frequency of utilization.In this case, for pulling in track switch that frequency is the highest, the tongue that the most easily occurs hurt maintenance and change and bring very large inconvenience, must study the structure being adapted to modern tram system features and service condition simple, can keep in repair, the heel of switch rail structure of easy-maintaining.
Current China track switch mainly adopts interval iron loose joint hair style tongue and elasticity flexible switch heel end structure two kinds of structural shapes.It is articulated structure that movable joint is equivalent to heel of switch rail, and tongue can freely be moved, and required conversion power is little.But complex structure, poor stability, is the weak link of turnout switch part, easily disease occurs.Elasticity flexible switch heel adopts common rail joint geometry, structure is relatively simple, firm, concerning the railway Ballast track of traditional open and ballastless track bed be easy to on-site maintenance maintenance, but adopt the heel of switch rail fixed form of ordinary couplings clamping plate still comparatively complicated for the modern tram track switch of embedded structure, rapid-maintenance requirement cannot be realized.Therefore, existing heel of switch rail structural shape cannot effectively be applicable to modern tram track switch.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simplification heel of switch rail structure for modern tram track switch, to effectively improve originally frequent but the maintenance of complexity and replacing program, realize dismounting fast and maintenance, effectively ensure that the normal operation of vehicle.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of simplification heel of switch rail structure for modern tram track switch of the present utility model, comprise tongue and the gear rail, the stock rail that lay respectively at its both sides, sliding table plate, base plate are set under tongue rail, it is characterized in that: described gear rail is welded as a whole with sliding table plate, base plate; Described tongue working edge, side, inoperative limit arrange respectively and form to it pressing plate, the buckle withheld, and this pressing plate welds with gear rail, sliding table plate, and this buckle is formed by high-strength bolt and sliding table plate and removably connects.
The beneficial effects of the utility model are, the tongue met under flush type track structure and high frequency of utilization condition changes requirement, improve more greatly originally frequent but the maintenance of complexity and replacing program, very easily realize dismounting fast and maintenance, effectively ensure that the normal operation of vehicle; More be adapted to simultaneously modern tram axle heavy little, speed is low etc. is different from the operation condition of general railcar, by proposing the schematic design of novelty to heel of switch rail fixed form, this structure processing and manufacturing is simple, there is good economy, reduce construction and the maintenance cost of modern tram system.
Accompanying drawing explanation
This manual comprises following two width accompanying drawings:
Fig. 1 is a kind of simplification heel of switch rail structure top view for modern tram track switch of the utility model;
Fig. 2 is the profile of a kind of simplification heel of switch rail structure for modern tram track switch of the utility model;
Component shown in figure and corresponding mark: base plate 1, sliding table plate 2, pressing plate 3, gear rail 4, tongue 5, buckle 6, high-strength bolt 7, stock rail 8, rut are with trimmer 9, dovetail part 10.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, a kind of simplification heel of switch rail structure for modern tram track switch of the present utility model, comprises tongue 5 and the gear rail 4, the stock rail 8 that lay respectively at its both sides, arranges sliding table plate 2, base plate 1 under tongue 5 rail.Described gear rail 4 is welded as a whole with sliding table plate 2, base plate 1.Described tongue 5 working edge, side, inoperative limit arrange respectively and form to it pressing plate 3, the buckle 6 withheld, and this pressing plate 3 welds with gear rail 4, sliding table plate 2, and this buckle 6 is formed by high-strength bolt 7 and sliding table plate 2 and removably connects.Vertical buckle press is provided by pressing plate 3, buckle 6 pairs of tongue 5 heel ends.
Owing to first base plate 1 and gear rail 4, sliding table plate 2 being welded into overall welding with backing connected components, weld assembly is assembled stock rail 8, stock rail 8 assemble qualified after assemble tongue 5 again, tongue 5 mainly adopts the fixed form of buckle 6 and pressing plate 3 simultaneously, more easily realize dismounting fast and maintenance, effectively can ensure the normal operation of vehicle.
With reference to Fig. 2, between described tongue 5 flange of rail side and pressing plate 3, buckle 6, be provided with rut with trimmer 9.Adjusted the lateral attitude of tongue 5 heel end by rut with trimmer 9, can adjust by Use Adjustment sheet 9 when gap, tongue 5 heel end flange of rail both sides is greater than 1mm.
With reference to Fig. 1, the described tongue 5 heel end flange of rail has dovetail part 10, to control the length travel of tongue 5.
Some principles of a kind of simplification heel of switch rail structure for modern tram track switch of the above the utility model that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
