Description
Technical field
The present invention relates to a kind of seamless track steel rail REPAIR WELDING vehicles, belong to railway machinery design and manufacturing technology field.
Background technique
There is a large amount of severely injured connector in rail track, using saw except severely injured section, the method for being inserted into new rail section can be to route
It completes to repair, common line is inserted into new rail length and is typically no less than 6m, and high-speed railway is inserted into new rail length and is typically no less than 20m.
Mainly new rail is connected in route using exothermic welding at present, but exothermic welding is difficult to ensure the quality of connector, to give route band
Carry out some potential safety problems.
Rail welding is divided into site welding and base welding, and domestic base welding at present mostly uses fixed Flash Butt Welding
Mode.Since the equipment of base flash welder is huge, the single devices for also needing to decompose after the completion of welding are handled, and are needed
Place is big, operator is more, work efficiency is low, fixed flash welder can not carry out transition simultaneously, thus considerably increases transport
It is difficult.Such as the fixed sudden strain of a muscle of 3.2.1 of text first page in " People's Republic of China's railroad industry standard " TB/T1632.2-2005
The fixed Flash Butt Welding production line of photocoagulation equipment requirement should have steel rail alignment machine, saw rail equipment, rail end rust removalling equipment, steel before weldering
Rail flashing butt welding equipment, postwelding rail straghtener, rail head weld seam refiner and welding point annealing device.But its there are still
Following shortcoming: 1, equipment land occupation is big, operator is more when using.2, alignment measuring device and flash butt welding before welding
Device separation easily generates wrong variable when use, directly affects welding quality.3, due to frequently encountering a plurality of PDL Construction
It carries out in succession, there are multiple work surfaces to construct simultaneously for engineering construction project, and rail equipment transition benefit inconvenient for use is welded in base.
Application No. is 200620019354.1 Chinese utility model patents to disclose a kind of mobile rail-welding vehicle comprising
By forward and backward horizontal frame and the vehicle frame that their intermediate arched girder constitutes is connected, bogie, hydraulic top below vehicle frame are set
Rise device and rail lifter, and the drivers' cab and powerhouse that are arranged on vehicle frame, it is characterised in that on the vehicle frame below arched girder
If with the shutter contact bonding machine with hanger.The space below vehicle frame arched girder can be made full use of, rail welding operation is both convenient for,
Center of gravity can be moved to below vehicle frame arched girder, increase whole vehicle stability, while keeping complete vehicle structure compact, easy to operate, flexible, operation
Safety；Also corollary equipment transport difficult is solved the problems, such as.But with the development of the times, it is impossible to meet present height
The job requirements of fast railway track reparation.
Summary of the invention
The farther away connector of set distance drivers' cab of the present invention is 1# connector, is 2# connector apart from the closer connector of drivers' cab；
The direction that parallel steel rails extend is longitudinal direction, is parallel to the direction of sleeper as laterally.
One aspect of the present invention provides a kind of seamless track steel rail REPAIR WELDING vehicle, including main car frame, is arranged on the main car frame
Drivers' cab, the drivers' cab rear are provided with the workshop for being covered in main car frame top, and main car frame both ends include hitch, in main vehicle
Frame lower part successively includes EEF bogie, air compressor machine, water tank, hydraulic power unit and tool box and hydraulic leg from the front to the back；The main vehicle
It is rack-mounted to carry new rail, power packet, diesel fuel tanks, end face processing machine, rail saw, gas are set gradually from the front to the back in the workshop
Body supply between, small machine, soldering tip refiner, rail regulating device, rail welding machine, the workshop further includes extensible canopy, should
Extensible canopy one end connects front door frame, which includes crane I and crane II, and extensible canopy is by roller supporting in main car frame
Supporting beam on, when guaranteeing main car frame operation, workshop sliding opposite with supporting beam, it is severely injured that rail is completely covered in formation one
The job shop in area, the supporting beam are installed on the main car frame.
Preferably, it is connect by upper roller, middle idler wheel, bottom roller with the extensible canopy above the supporting beam.
It is further preferred that the supporting beam is symmetrically arranged centered on extensible canopy, the upper roller, middle idler wheel and institute
It states bottom roller to be inlaid in a manner of clearance fit respectively in the sliding rail of the extensible canopy, to make the extensible canopy in the branch
It is slided on support beam.
In any of the above-described scheme preferably, the supporting beam includes the pillar of vertical direction and connect with the pillar
Cross-brace, the pillar and the cross-brace arrange that the cross-brace end includes about the extensible canopy axial symmetry
The middle idler wheel, central axis of idler wheel is vertical direction vertically in this, so that the extensible canopy is in this under drive of idler wheel
Transversely slid relative to the supporting beam；The central axis of the upper roller and bottom roller is laterally setting, is stretched convenient for described
Contracting beam is under the drive of the upper roller and bottom roller along straight skidding.
In any of the above-described scheme preferably, the front door frame includes support device, when operation, support device decline
And be supported on sleeper and railway roadbed, so that workshop is relatively smooth fixed on railway roadbed.
