Description

A kind of online one-pass molding milling rail equipment of profile of steel rail
Technical field
The utility model relates to a kind of online one-pass moldings of profile of steel rail to mill rail equipment, especially railway track rail head profile The processing method reshaped is repaired, railway track online milling maintenance technology field is belonged to.
Background technique
In recent years, China express railway and city underground transport development are rapid, as operation amount and time increase, rail table Surface damage problem is more prominent, and common type of impairment has track side abrasion, wave mill, overlap etc., if these diseases are repaired not in time, It will affect rail service life and train operation safety.To guarantee train operational safety and stability, it is necessary to using quick Efficient online trimming techniques eliminate Rail Surface Abrasion, restore the good profile of rail.
Online rail trimming techniques mobile at present have steel rail grinding and two kinds of rail milling.Application publication number CN 104612005 A provide a kind of processing method for reshaping rail head of rail profile, use along rail longitudinal two groups of front and back arrangement Engagement facing cutter or one group of facing cutter add one group of mill to carry out roughing and finishing to rail.Application publication number CN 104911965A provides a kind of mobile device of rough milling for milling rail equipment, includes at least seven sides on each knife rest of facing cutter Shape blade and two curved surface blades first pass through and rough mill device to rail head of rail surface milling molding, then with finish-milling device to rail head Surface carries out finish-milling trimming.The milling cutter dish structure installed is mainly using such as awarding on existing rail milling vehicle or milling rail vehicle Structure type disclosed in notification number CN206622682U is weighed, i.e., is circumferentially evenly distributed with the identical cutter holder of multiple groups, every group of cutter holder on cutter head 2 circular arc blades of upper installation and 6 square blades.Using the milling attachment of the form, copy milling is carried out to Rail Surface profile After cutting, rail head of rail surface damage is essentially eliminated.But have the disadvantage that (1) several square blades mill Rail Surface The imitative standard profile being made of several straightways formed after cutting, therefore knife rib trace can be generated in X direction, to improve rail level Precision is rebuild, need to use and rough mill device+finish-milling device or the progress milling (milling of milling attachment+grinding attachment combination operation mode Mill).A large amount of high-temperature dust particles in Mars form can be generated when specifically, using steel rail grinding mode operation, not only sternly The health of staff is endangered again, and great security risk can be also brought to field fireproof.(2) when subway line Rail Surface wheel When exterior feature is rebuild, existing milling vehicle is since structure is complicated, weight is larger, it is difficult to which the maximum allowable axle load for meeting subway permission is wanted It asks.
The utility model is in view of the above problems and insufficient, designs a kind of online one-pass molding milling rail equipment of profile of steel rail, makes A milling operation is only needed with the milling rail equipment, curved surface knife grain combination blade that a combination thereof formula facing cutter is formed and rail head of rail Standard profile fits like a glove, and can satisfy route Rail Surface precision and ride comfort requirement.Compared with existing milling bassinet structure, subtract A set of grinding attachment or finish-milling device are lacked, the manufacturing cost of milling vehicle not only can be greatly reduced, mitigate complete vehicle weight, while energy Enough bigger space is provided for the optimization of milling bassinet structure and performance boost.
