Description
Technical field
The present invention relates to a kind of rail grinding machine for grinding rails, relate in particular to a kind of rail grinding machine grinding head vertical lift device.
Background technology
Rail is the critical piece of track traffic, and rail directly contacts with the wheel of train, and the quality of its quality directly has influence on safety and the stationarity of driving.After operation is opened in track traffic; rail is just for a long time in rugged environment; the reasons such as dynamic action, natural environment and the quality of rail own due to train; often can there is hurt situation in rail; as phenomenons such as crackle, abrasion; cause rail life minimizing, the increase of maintenance work amount, maintenance cost to increase, even have a strong impact on traffic safety.
In prior art, rail grinding machine is repaired polishing by emery wheel High Rotation Speed to rail.The lifting of the emery wheel of rail grinding machine and decline directly drive by Hydraulic Elements.
At least there is following shortcoming in above-mentioned prior art:
In steel rail grinding process, hydraulic drive is easily leaked, the response time is long, efficiency is low.Because the viscosity of hydraulic oil is large, compressibility is poor, when rail grinding ripple when abrasion mill, can cause damage to carrying out Hydraulic Elements, affects Hydraulic Elements application life.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, flexible movements, efficiency is high, the life-span is long rail grinding machine grinding head vertical lift device.
The object of the invention is to be achieved through the following technical solutions:
Rail grinding machine grinding head vertical lift device of the present invention, comprise polishing unit, described polishing unit comprises cradle frame, in described cradle frame, a plurality of grinding heads are housed, described grinding head comprises grinding wheel and polishing motor, described grinding head is arranged in described cradle frame by vertical lift device, and described vertical lift device comprises parallel-crank mechanism, and described parallel-crank mechanism is connected with cylinder.
As seen from the above technical solution provided by the invention, the rail grinding machine grinding head vertical lift device that the embodiment of the present invention provides, owing to realizing parallel-crank mechanism by cylinder, control the vertical movement of grinding wheel, simple in structure, low cost of manufacture, reliable operation, design are ingenious, can meet the needs of rail grinding train polishing unit.
