Abstract
The utility model discloses a steel rail grinding wagon which comprises a wagon frame. A grinding unit is arranged on the wagon frame, walking wheels are arranged on the lower portion of the wagon frame, the wagon frame is suspended on a grinding train, and a lifting hydraulic cylinder, a locking device and a traction device are arranged between the wagon frame and the grinding train. The steel rail grinding wagon can correct wavy wear of rails and wheel rail scratching, can overcome the defect of inner-outer rail inclining deformation, can overhaul wheel rail contact faces and is suitable for large railway maintenance operation and linear and curved steel rail grinding.
Description
Technical field
The utility model relates to a kind of rail prosthetic device, relates in particular to a kind of rail grinding machine.
Background technology
The 1950's, along with the fast development of various countries' economy, railway transportation freight volume and the speed of service are comparatively fast developed.Thereupon, rail waveform wears away, contact fatigue equivalent damage is more and more serious, affects safety and the economy of railway transportation.It is more and more important that the maintenance of rail just seems, occurred rail grinding machine, and rail is carried out to sanding and polishing.
In prior art, divide two kinds of rails exterior features and ripple mill polishing dolly according to rail profile abrasion polishing dolly, can in job run, carry out preventative and reparation property grinding to the rail on circuit, the diseases such as the abrasion of rail undaform, rail lip, saddle shaped abrasion, welding depression and fish scale crackle are polished, thereby improve the profile of rail head working portion.Extend rail application life, improve wheel rail relation, reduce noise, improve safety and reduce maintenance cost.
At least there is following shortcoming in rail grinding machine of the prior art:
Complex structure, cost are high.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, rail grinding machine that cost is low.
The purpose of this utility model is achieved through the following technical solutions:
Rail grinding machine of the present utility model, comprises vehicle frame, and described vehicle frame is provided with polishing unit, and the bottom of described vehicle frame is provided with road wheel, and described vehicle frame is suspended on polishing train, between described vehicle frame and described polishing train, is provided with lifting hydraulic cylinder.
The technical scheme being provided by above-mentioned the utility model can be found out, the rail grinding machine that the utility model embodiment provides, because vehicle frame is provided with polishing unit, the bottom of vehicle frame is provided with road wheel, vehicle frame is suspended on polishing train, between vehicle frame and polishing train, is provided with lifting hydraulic cylinder.Can revise the wavy wearing and tearing of track, wheel track scratch, carry out the preventive maintenance of circuit rail, cost performance is high, maintenance cost is low.
Brief description of the drawings
The structural representation of the rail grinding machine that Fig. 1 provides for the utility model embodiment.
In figure:
1, lifting hydraulic cylinder, 2, draw-gear, 3, polishing unit, 4, locking device, 5, road wheel, 6, vehicle frame.
Detailed description of the invention
To be described in further detail the utility model embodiment below.
Rail grinding machine of the present utility model, its preferably detailed description of the invention be:
Comprise vehicle frame, described vehicle frame is provided with polishing unit, and the bottom of described vehicle frame is provided with road wheel, and described vehicle frame is suspended on polishing train, between described vehicle frame and described polishing train, is provided with lifting hydraulic cylinder.
Between described vehicle frame and polishing train, be provided with locking device.
Described vehicle frame and polishing are provided with draw-gear between train, one end of described draw-gear and described polishing train are hinged, the other end and described vehicle frame hinged.
Described rail grinding machine is the wide grinding machine of rail or ripple mill grinding machine.
The wide grinding machine of described rail comprises four groups of polishing unit, and every group of polishing unit comprises two grinding heads.
Described ripple mill grinding machine comprises two groups of polishing unit, and every group of polishing unit comprises four grinding heads.
Specific embodiment:
As shown in Figure 1, comprise that a lead frame (vehicle frame), four are for controlling the lifting hydraulic cylinder, locking device, draw-gear of dolly lifting and polishing unit that can deflection etc.Vehicle frame is provided with four wheels with wheel rim, when polishing, travels in orbit.Draw-gear is realized bivector traction operation by a draw bar.
When polishing operation, the polishing motor of polishing unit promotes, locking device release, and dolly dolly under deadweight falls into rail level, and polishing unit deflection angle is set, and motor drives grinding wheel to carry out polishing operation to rail level.
Rail grinding machine comprises rail wide polishing dolly and ripple mill polishing dolly, its main distinction unit difference that is to polish, and the wide polishing of rail dolly has four groups of polishing unit, and ripple mill polishing dolly has two groups of polishing unit, other parts are identical or similar.
Rail grinding machine sends instruction by the Electric control system of polishing, and controls hydraulic system, pneumatic system, electrical system etc. and completes mechanism action, completes polishing operation.
Rail grinding machine of the present utility model, can revise the scratch of the wavy wearing and tearing of track, wheel track, and in correcting, outer rail inclination and distortion and finishing running surface of wheeltrack etc. are various due to the vehicle steel rail defect producing that travels on rail, carry out the preventive maintenance of circuit rail.Be applicable to large-scale road maintenance operation, to straight line, curved steel rail polishing.Grinding machine cost performance is high, maintenance cost is low.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
