Description
Technical field
The utility model relates to a kind of interim overhead devices of the route for non-fragment orbit Disease Treatment, belong to railway ballastless
Track disease technology for eliminating field.
Background technique
With the development of high-speed railway, non-fragment orbit is since its ride comfort is high, rigidity uniformity is good, track geometry is protected
The features such as lasting and be widely used in high-speed rail route.Operating practice shows that ballastless track structure state is overall in recent years
Normally, but under long-term train operation load and external environment effect, screed bonds degradation failure, armored concrete bearing
, occasionally there is generation in the case where layer hurt, the arch of track plank split, causes track geometry bad, brings very to route normal operation
Big security risk.Disease once occurs for track structure, should carry out reparation regulation to it in time, when repair influences track knot
When the safety and stability of structure, such as replacement track plates, concrete support layer cut reinforcing, need to take measures to face existing line
When it is aerial, repair is carried out in the case where not influencing train operation.
Currently, few interim overhead methods for non-fragment orbit, traditional overhead basic skills of operating line hangs/
Detain rail method, steel I-beam method and D type just beam method etc..Hanging/detain rail method is to be connected into more loose rail by bolt and angle steel
Rail beam and a kind of aerial construction for constituting aerial system stringer, hanger rail beam are distributed in stock rail two sides, rail girder above sleeper
Then it is located at below sleeper immediately below stock rail or is located at outside route sleeper, crossbeam is crossed between sleeper, crossbeam both ends ride over longitudinal direction
On rail beam, and stock rail is then fixed on crossbeam；Steel I-beam method is similar to hanging/detaining rail method structure, by utilizing Hot-roller
Shaped steel replaces hanging/detaining the rail in rail method and constitute the longitudinal beam structure in aerial system, can be divided into I-steel hanging beam method and base
Two kinds of forms of I-steel beam beam method under this rail；Just beam is the sizing steel beam structure made by factory dedicated for fixed track usage plan to D type,
Structure is generally made of two panels I-shaped steel longitudinal beam and Duo Gen needle beam, and crossbeam and stringer are stitched together by high-strength bolt, steel
Rail then passes through mating fastener and is directly anchored on crossbeam, on the basis of just beam overall structure is fixed on by lower 4 supports of two panels stringer.
Application No. is 201610605003.7 Chinese invention patents to disclose one kind for railway ballastless track supporting layer
The interim rail support device changed, the device mainly includes steel bearing beam main bodys and changeover portion sleeper two large divisions.Steel bearing beam master
Body is made of two I-shaped big stringers and Duo Gen needle beam, wherein two stringers are located at immediately below two rail, stringer
Between connected by crossbeam, steel bearing beam both ends in concrete support layer, are set up in above disease area by seat supports, are constituted
Certain construction space.Between steel bearing beam both ends and normal orbit plate, the transition rail of respective numbers is set according to length difference
Pillow.Steel bearing beam and sleeper support operating line rail jointly and constitute interim overhead transmission line.
Since high-speed railway is more demanding to train operational safety and stationarity, and ballastless track structure height is relatively
Low, construction space is limited, and traditional operating line overhead method can not be advantageously applied to the interim aerial of non-fragment orbit.
It hanging/detains rail method and I-steel beam beam method applies in general to the lesser occasion of narrow space, span, the load of receiving is little, and by
It is made of in rail beam and I-steel beam more loose individuals, causes that the aerial construction is erroneous for installation, stability is poor, reliable
It spends not high；Every stringer is monolithic I-steel in I-steel hanging beam method, and crossbeam is matched sizing steel sleeper, stringer, crossbeam and base
It is bolted between this rail, but aerial fulcrum uses concrete caisson, and i-beam structure size is larger, is not suitable for
The occasion of narrow space；Just beam is the sizing steel beam structure made by factory dedicated for fixed track usage plan to D type, high with intensity,
The feature that rigidity is big, span is big and reliability is high, but just beam is generally used for building the field of structures under Ballast track is both wired D type
It closes, beam body volume and quality are excessive, and convenience is poor, operation is more difficult, are difficult to be applied to the interim of non-fragment orbit and make somebody a mere figurehead.
In aerial scheme disclosed in Chinese invention patent application No. is 201610605003.7, since steel bearing beam is vertical greatly
Beam uses i shaped cross section form, causes beam body length and span relatively small, in steel bearing beam both ends or certain one end and positive normal practice
There are clear band between guidance tape, clear band then must be provided with transition spacing timber route rail, and overhead transmission line is by steel bearing beam and more
The loose sleeper composition of root, constructs cumbersome, overhead transmission line globality, stability are poor；Support used by steel bearing beam and limit dress
It is set to the structure of single fixation, beam body is can not achieve and is adjusted in vertical and lateral position, causes this kind of overhead device more difficult suitable
Regulation for certain special disease operating conditions；For renovating the longer situation of range, which can only use section construction
Method, repairing efficiency is long.
