Description
Technical field
The present invention relates to a kind of maintenance conditions method and device of railway infrastructure, and in particular to a kind of high-speed railway
The maintenance conditions method and device of bridge, is run with the normal safe for ensureing high-speed railway bridge, category railway infrastructure detection
Maintenance technology field.
Background technology：
With developing rapidly for high-speed railway, China's high-speed rail bridge gets a lot of applications in high ferro, and present China is high
Metal bridge beam is mainly characterized by：Bridge the line is busy road ratio is big, and multispan is overhead, bridge long, Longspan Bridge are more；Design speed per hour 300km,
The Passenger dedicated railway Bridge of 350km all uses non-fragment orbit；Use to wait the whole hole prestressed concrete of 32 meters of two-wires across arrangement
Simple supported box beam is principal mode structure, on a small quantity 24 meters of simple supported box beams of configuration.
Calculated by 1.3 ten thousand kilometers of existing line, China's high-speed rail bridge at least more than 5,000 kilometers.Bridge is used as bullet train
The carrier of running track, to ensure security, stationarity and the ride comfort requirement of high ferro visitor's special line high-speed cruising, it is necessary to
With high ride, high stability and high reliability.By the traffic accident that bridge hidden danger is brought, often car crash
Serious accident, therefore constantly detection, maintenance, the means and equipment of maintenance of lifting high-speed rail bridge, it appears more important and urgent.
Because railroad bridge is important part in high ferro circuit, detection and dimension of China's high ferro management level to bridge
Shield is increasingly paid attention to, and the rail-mounted bridge-checking vehicle of railway is to substantially meet high-speed railway bridge maintenance now to be set with the one kind safeguarded
Standby, still place enters to research and develop the primary stage at home, substantially based on introduction.
Railroad bridge maintenance conditions device can be divided into bridge floor main line track walking type, bridge case according to the method for operation substantially
The special walking rails formula of web built-in fitting, pavement walking type and ground cross-country.
（1）Bridge floor main line track walking type bridge checking device
It is traveling track with railway main line track, travel speed is fast, Stability Analysis of Structures, technology are more ripe, has both at home and abroad
Using.Rail-mounted bridge checking device, either basket-hanging or truss-like are required for taking high ferro operation passage, therefore can only be
Run under the conditions of high ferro operation " skylight ", and high-speed railway running train density is big, it is desirable to punctuality rate is high, and it is not to open up " skylight "
Reality, and its Working mechanism protrudes horizontally up from circuit both sides, is limited by the contact net of circuit both sides, is worked completing one
After point, Working mechanism must be retracted to the state of reorganizing and outfit avoids contact net could run to next operating point.Two operating points
Between, operating personnel must repeatedly manipulate implement retractable, not only inefficiency, staff be also easy to it is tired out, this show
High speed so with high-speed railway, efficient requirement are runed counter to.
（2）Bridge box and beam web built-in fitting dedicated track walking type bridge checking device
It is traveling track with bridge both sides dedicated track, bridge machinery operation, technology can be carried out with manpower or driven by power
There is the GQJ-P of Zhuzhou Guo Tie Industrial Co., Ltd.s ripe, Stability Analysis of Structures, the country;The range of models bridge checking device such as GQJ-G（And in
Patent, the patent No. are declared within 2011：ZL 2011.2 0164584.8）But, the built-in fitting of the bridge checking device need to set in bridge
At the beginning of meter will design arrangement, during beam processed in bridge web pre-buried trapped orbit support built-in fitting, and need set
Built-in fitting, track and track support quantity are more, and installation risk is larger, and totle drilling cost is higher.And existing high-speed rail bridge percent
More than 98 do not have pre-plugged built-in fitting, it is impossible to install dedicated track walking type bridge checking device.
（3）Pavement walking type bridge checking device
Pavement with railroad bridge both sides is to walk row of channels, at home and abroad there is application, such as MOOG companies of Germany MBS90
The desk-top bridge checking device of type sidewalk traveling.China is after high-speed railway bridge in 2008 has carried out optimization design, it is considered to bullet train
Traffic safety, do not allow personnel and miscellaneous equipment to pass through during train operation, on bridge floor, catenary mast is arranged at outside pavement
Side, therefore pavement walking type bridge checking device has not been suitable for country's high-speed rail bridge now.
（4）Ground cross-country bridge checking device
Ground sidewalk or field meadow under bridge are run on, closely bridge machinery and dimension are implemented by foldable arm rack hanging basket
Repair.The device is not suitable for the region that traffic above-ground limitation can not run, such as：Rivers, mountain area, farmland etc., applicable interval are smaller,
And being influenceed larger by bridge height and ground surface or terrain, applicability is poor, inefficiency.
And from 2008, high-speed railway bridge carried out bridge deck Optimized Improvement Design, it is considered to which bullet train runs
Safety, does not allow the upper bridge of personnel and miscellaneous equipment to pass through during train passage, contact line pillar is arranged at pavement outside, and bridge floor is not
Pavement formula is set and checks car, completely closed under bridge, without the current sidewalk of setting.Therefore, high-speed rail bridge detection means requirement has
Efficiency high, security are good, strong adaptability, the low advantage of power consumption, it is adaptable to the preventive inspection of high-speed railway bridge and dimension
Detection operation is repaiied, and for operator provides safety guarantee in each part of detection bridge.Therefore Chinese metal bridge high is combined
The actual national conditions of beam, a kind of novel high speed railroad bridge maintenance of research and development, detection means are imperative.
By patent retrieval do not have discovery have with the constructed patent literature of the present invention, have certain relation with the present invention
