Description
Technical field
The present invention relates to a kind of railway track maintenance method, particularly a kind of railway track profile milling trimming mode, and corresponding equipment.
Background technology
Rail is the important equipment of rail track, in actually used, it is determined that the rational life cycle of rail, carries out rail land use reform by stages, and actively carries out the dress work of old rail. The trimming of old rail is generally divided into three classes: long rail string is used in comprehensive shaping rail, general shaping rail and welding again. Rail trimming techniques: rail end irregular wear and fall block, scratch is one of the principal mode of various traumas and the defect produced in rail operation process. These diseases cause the huge additional impact power of rolling stock, make circuit change table aggravate, and not only shorten the service life of each parts of track, but also increase maintenance workload. Accordingly, it would be desirable to Rail Surface disease is renovated in time. The renovation of Rail Surface includes mill and repaiies and repair welding. The purpose repaiied according to rail mill and stock removal, rail mill is repaiied and can be divided three classes: (1) maintenance grinding, being mainly used to eliminate the shape of a saddle abrasion of the waveform abrasion of rail, wheel flat, rail crackle and joint, a stock removal of rail is relatively big, and the polishing cycle is long. But this polishing mode can not eliminate and causes ripple mill, rail stripping and fall the potential Contact Fatigue Crack Propagation of block, and when train passes through afterwards, continuation is also extended by these crackles. (2) preventive grinding, preventive grinding is to be destroyed in this this crack initiation district before crackle starts extension, recently has evolved into the technology controlling rail contact fatigue. It try hard to control Rail Surface contact fatigue development, polishing the cycle shorter, in order to just eliminated when Rail Surface crack initiation. (3) rail profile profile polishing, carries out asymmetric polishing to the rail profile of 3 in Curve Segment and can substantially reduce wheel-rail lateral force and the angle of attack, reach to alleviate the purpose of track side abrasion.

More multioperation is all known for those of ordinary skills, repeats no more.
The technical scheme of railway track profile trimming device provided by the present invention includes the combination in any of each part mentioned above, and simple change or the combination of each part mentioned above assembly are still protection scope of the present invention.
Railway track profile trimming device provided by the present invention adopts the layout type of front frame and the such at least two vehicle frame of Rear frame, front frame being arranged, 1 to n overlaps diameter and is not less than the milling dish of 600mm and 0 to n overlaps the mill that diameter is not less than 800mm, in the Rear frame top each dynamical system of rational deployment and control unit, milling dish diameter is maximum reaches 1400mm, when adopting 1400mm major diameter milling dish, it is made to have bigger inertia and more cutter grain when milling, cut vertical component less, cutterhead work is more stable, the cutter grain life-span is longer, and it is little of 0.0045mm to remain wave amplitude after milling. Milling Speed compares 600mm diameter milling dish, and maximum operation speed is increased to 1.8kM/h, and working performance is higher. and owing to adopting changing knife frame mode flexibly to carry out cutter grain replacing so that working performance improves, operating cost reduces. compared with traditional rail plastic operation mode, this car is highly suitable for that disease is heavier and major long tunnel, subway, light rail etc. need the construction site of environmental protection, have following distinguishing feature:
(1) working performance is high: first pass, rail level milling depth is up to 0.3��1.5mm, and gauge angle milling depth is maximum up to 5mm. Can thoroughly eliminate longitudinal wave mill and various rail level disease.
(2) homework precision is high: rail cross-sectional outling precision is up to �� 0.2mm, and rail longitudinal smoothness precision is up to �� 0.02mm, and rail level smoothness, up to 3��6 ��m, has delayed the appearance of new round longitudinal wave mill and rail level disease.
(3) operation effectiveness is good: all longitudinal waves mill in 400mm wave-length coverage all can thoroughly eliminate; Rail level does not have the defects such as micro-rill, spot, stress concentrated layer, overheated, enameling.
(4) operation restriction is few: operation is not affected by factors such as the electric attachments of track, road junction, guard rail of bridge; Throughout the year all can operation.
(5) reorganize and outfit the time short: the time of reorganizing and outfit needed before and after operation is few, and cutter group is changed quick and convenient, improves the utilization rate in block skylight.
(6) environmental effect is little: milling operation, without water source, does not have Mars and splashes, without fire hazard in operation process; The iron filings of 99% and dust recovery rate, without on-the-spot residue after operation.
Additionally, the structure of operation bogie can ensure under working condition, between gear-box with bogie frame, realize rigid suspended connection, the temporary impact produced when cancel job drives; When ensureing high-speed cruising simultaneously, realize resilient suspension between gear-box with bogie frame and be connected, it is prevented that the driving that gear-box is produced by high-speed cruising is impacted excessive and caused that gear-box hangs damage or comes off, and causes traffic safety accident.
