99% iron filings and dust recovery rate, without live residue after operation.
Railway track profile milling-grinding equipment of the present invention can enter Mobile state in work is run to the rail on circuit
Milling and polishing operation, polishing operation processing is carried out for general rail abrasion, and milling work is carried out for depth rail failure
Industry processing, the defects of eliminating the side grinding of rail, ripple mill, rolling layers, crack, stripping, so as to recover the design of rail head working portion
Shape.Following target can be realized：Improve rail service life；Improve rail longitudinal smoothness and cross-sectional outling quality (subtracts
Few rail wear, improves wheel/rail contact geometric state, reduces wheel track relative wear)；Reduce rail maintenance cost and recycle into
This；Reduce operation noise and improve that road network is safe for operation and efficiency of operation.
Railway track profile milling-grinding equipment of the present invention is using two layout type for saving cars, i.e. A cars+B cars, in A cars
The upper a set of a diameter of 1400mm of arrangement milling disk, arrangement mill equipment, each dynamical system of rational deployment and control unit on B cars,
It is rationally distributed, due to using 1400mm major diameter milling disks so that it possesses larger inertia and more knife grains in milling, cuts
It is smaller to cut vertical component, cutterhead work is more stable, and the knife grain life-span is longer；And remain wave amplitude as low as after milling
0.0045mm；Rail profile precision and longitudinal smoothness precision are more excellent after milling operation；Milling Speed compares 600mm diameter millings
Disk, maximum operation speed improve higher to 1.8kM/h, operating efficiency.
In addition, the structure of operation bogie can ensure under working condition, rigidity is realized between gear-box and bogie frame
Suspension connection, temporary impact caused by cancel job driving；Simultaneously when ensureing high-speed cruising, gear-box and bogie frame it
Between realize resilient suspension connect, prevent high-speed cruising to caused by gear-box driving impact it is excessive and cause gear-box suspension damage
Or come off, cause traffic safety accident.
