Description
Technical field
The utility model relates to a kind of railroad track coupling arrangement, and particularly a kind of high speed railway track orbit determination is apart from damping antivibration coupling arrangement.
Background technology
Railroad track connecting mode now commonly used be by two connect Tou Fish tail clamping plate (GB184-63, GB185-63), in rail (GB181-63, GB182-63, GB183-63) both sides bolton.Though it is easy to construct, because the linear thermal expansion of rail causes the rail connection place must reserve certain interval, to guarantee the extendable room of rail when the linear thermal expansion.And during train ran at high speed, the wheel shafts connected the bump of gap location and vibration and the harm that brings at rail, were the principal element that limit speed per hour that wheeled train is run at high speed is difficult to surmount so far.
The relevant programme that known solution rail connects the gap is divided into following type: 1, inclined-plane single hop gap-like.2, ladder overlap span class.3, fork wedge overlap span class; 4, V-type and the seamless class of X type; 5, no seam welding class.
The 1st class, easy to be reliable for perfect rigidity connects, but its section rail connection place, gap, supporting capacity is low, and the part is easy to wearing and tearing, causes the whole one steel rail phase of being on active service to shorten greatly.
The 2nd class also for perfect rigidity connects, but because of limitting the construction plant, is difficult for processing, and difficulty is changed in maintenance, and its section rail connection place, gap, and supporting capacity is low, and the part is easy to wearing and tearing, causes the whole one steel rail phase of being on active service to shorten greatly.
The 3rd class, also for perfect rigidity connects, not only the construction plant is limit, and is difficult for processing; Be exactly in the processing of guard station factory building, also take a lot of work and mistake, difficulty is more changed in maintenance, its section rail connection place, gap, and intensity weakens, and supporting capacity is low, and the part is easy to wearing and tearing, crackle, causes whole one steel rail to scrap in advance.
The 4th class, for full flexible connects, the rail connection place, supporting capacity is low, the special shape sleeper of the use that for this reason has, set up non-yielding prop, not only structure is numerous and diverse, and very difficulty is changed in maintenance, and rail connecting section place can not sink synchronously with non-connecting section, stay potential safety hazard, X shaped steel rail coupling head has increased construction ground again and has been difficult for processing another potential safety hazard that changes with the inboard gauge of railroad track.
With four classes of going forward, have only the V-type of the 4th class, have abroad outside the application, all the other are all because of poor practicability, and popularization is not applied.
The 5th class, though having done fruitful test in the environment in Plain, Europe, no seam welding class France explores, as adopt electroslag welding welding procedure, plasma panel welding technology on construction ground rail is welded, complicated procedures of forming such as weld seam shaping, heat treatment, polishing, shot-peening, flaw detection connect rail, with the quantity of relative minimizing coupling head, connect the bump of gap location and vibration and the harm that brings at rail thereby reduce the wheel shafts.China has tried out on the railroad track of speed-raising and has adopted this technology, and several rail welding are become 250 meters superlong steel rail, implements to be welded with dual mode: 1, this associating welding equipment of import, in the welding of construction ground; 2, in the factory building of guard station, after the welding, transport construction ground to the dull and stereotyped train spreading of more piece.This associating welding equipment of one side import, system is huge, technology is too complicated, the transportation difficulty, construction cost is high, consuming time to delay work, and runs into the bend mountain region and is difficult to popularization and application more; The rail that prolongs of rigid connection has strengthened resonance effects on the other hand, and the preset clearance that makes rail connect accumulation when reducing the quantity of coupling head has also increased several times simultaneously, and handles the limit preset clearance of this accumulation, becomes a new difficult problem.Mode is remedied in the thermal contraction of another kind of integral memory alloy, can offset the track thermal expansion, but involve great expense, and alloy strength is low, is difficult to use.
China utility model patent notice of authorization CN2393905 discloses a kind of fork type rail connector, belong to the combination of the 1st, 2,3 above-mentioned classes, be to utilize like the main body of fork shape and interlaced combination of accessory body structure of chock shape seemingly, by inserting the intermediate plate in the body recess, be installed on the pre-stress type cement sleeper, cross noise and the covibration that gap produces in order to eliminate pressure wheel.Though interlaced combination helps the concentrated stress of dispersed steel rail coupling place.But also there are some problems,, heavyly repeatedly are subjected to load to be easy to produce fatigue crack and lost efficacy as on the one hand the inboard root in its rail longitudinal fluting place is thin; Its body recess almost can't shape on the other hand, existing rail is promptly to implement roll forming at the hot base that steel mill's conticaster flows out without cooling, rollingly on the roller-way can not obtain the required flute profile of its body recess, all make processing cost very high and lose practicality with die forging mode or cold worked metal cutting mode, line cutting and electric spark mode.The pre-stress type cement sleeper of its proposition, no doubt help to reduce resonance effects, its complicated implementation is not said, concentrate the talk of the common sleeper several times of its floor space, like this, shake through pressing repeatedly in the train operation greater than non-connecting section, very long relatively non-connecting section can not sink synchronously with the connecting section rail of extremely lacking, cause railroad track to occur day by day being uneven, generation distorts, the harm train operating safety.
