Description

Mobile steel rail milling car

Technical field

The utility model relates to a kind of mobile steel rail milling car, especially a kind of for rough milling railway line steel rail and the mobile steel rail milling car of finish-milling, belongs to engineering equipment technical field.

Background technology

In recent years, rapidly, the raising of adjoint freight volume increase and the speed of service, Rail Surface Abrasion problem starts more and more to give prominence to China's track traffic development, and wherein common damage has rail rolling contact fatigue crackle, ripple to grind and curve upper end track side abrasion.If Rail Surface Abrasion can not get rebuilding in time, effectively, traffic safety and rail application life will be had a strong impact on.

In order to ensure the safety of train operation, stability and comfortableness, improve Wheel Rail Contact state, reduce wheel-rail noise, improve the application life of rail, slow down Rail Surface hurt expansion rate simultaneously, portable online trimming techniques fast and efficiently must be adopted to eliminate Rail Surface hurt, to recover the good profile of rail and smooth degree.The online rail trimming techniques of current movable type has steel rail grinding and rail milling two kinds.

Two kinds of modes that steel rail grinding has polishing train to polish and artificial facility are polished.Steel rail grinding can to a certain degree repair rail surface hurt, to ripple mill and tread facial cleft line with to peel off block repairing effect obvious; But when hurt is more serious, need the polishing carrying out multipass secondary to repair well, and polishing quality is not easy to control, operating efficiency is lower.If manual polishing, then effect of polishing depends on the qualification of human users's machinery, the more difficult guarantee of quality.In addition, when steel rail grinding is by small-radius arc (as the fat edges) of repairing gauge angle or lateral angle, if excessively polishing or power of motor arrange improper, then circular arc may be tied and destroy rail head shape, be not easy to revert to smoother profile.In addition, mechanization rail grinding train easily produces the spark of splashing, metallic dust and noise when operation, understand contaminated air, worsen operating environment, cause fire, even affect post-job normal operation, the problem that in tunnel, operation brings is then even more serious, also needs to remove the trackside equipment such as check rail, communication cable before polishing operation, and need change grinding wheel, and suitable motor position is set to obtain the rail head shape of needs, so operation time is longer.Therefore rail grinding machine iron wire road inappositely.

Current rail milling car then mainly comprises milling and polishing two cover programs, first longitudinal milling is carried out to Rail Surface, subsequently by the Rail Surface of milling is polished, eliminate the corner angle of Rail Surface, rail milling can mill away Rail Surface hurt quickly, is applicable to eliminating end face ripple mill, crackle and peeling off the hurts such as block.To more serious surperficial hurt, also can be realized a milling by the setting of cutting output and namely repair steel rail defect; Its Rail Surface smooth degree recovers better, and operating efficiency is higher.Simultaneously, by pre-designed cutter grain arrangement mode, the adjustment that operation need not carry out knife rest early stage just can recover rail cross-sectional outling, the fat edges of applicable elimination gauge angle, lateral angle or plastic strain, its operation preparation is less, also do not need to remove trackside equipment, the pollution of operation to air, noise is little, and the advantage used in the location that the environmental requirements such as urban track traffic tunnel are higher is then more remarkable.

At present, railway track also mainly application polishing train repair and safeguard rail failure, individual businesses is only had to carry out the research of rail milling car in the world, existing milling car is all the working method adopting milling and polishing to combine as previously mentioned, decrease spark, metallic dust and noise etc. that operation produces to a certain extent, but grind this operating type still to exist, the pollution of operation to environment still exists.

In sum, be badly in need of a kind of mobile steel rail milling car that can be applied to rail restoring on line, not only make up domestic technological gap, the reparation completely of rough milling the mode combined with finish-milling and realizing rail failure or defect can also be adopted completely, reduce operation further to the pollution of environment simultaneously.
