Abstract
The invention discloses a tilting device of a grinding unit of a rail grinding wagon. The grinding unit comprises a cradle frame. A plurality of grinding heads are fixed into the cradle frame and comprise grinding wheels and grinding motors. The cradle frame is hinged to a frame body of the rail grinding wagon, and a hydraulic cylinder is arranged between the cradle frame and the frame body. The grinding unit is provided with a tilt angle indicating device and an angular displacement sensor. The hydraulic cylinder is connected with a hydraulic lock. The grinding unit is suitable for various rail grinding wagons and used for correcting rail wavy abrasion and wheel rail bruise, overcoming various rail defects, generated when a vehicle runs on a rail, such as inner and outer rail tilting deformation and wheel rail contact surface finishing and conducting preventive maintenance of the line rail. The tilting device is high in cost performance, convenient to rotate and low in maintenance cost.
Description
Technical field
The present invention relates to a kind of rail prosthetic device, relate in particular to a kind of rail grinding machine polishing unit tilting gearing.
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, according to rail profile abrasion polishing dolly, divide two kinds of rails exterior features and ripple mill polishing dolly, can in job run, to the rail on circuit, carry out preventative and reparation property grinding, 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:
Polishing block construction is complicated, rotation is inconvenient.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, rotate easily rail grinding machine polishing unit tilting gearing.
The object of the invention is to be achieved through the following technical solutions:
Rail grinding machine polishing of the present invention unit tilting gearing, polishing unit comprises cradle frame, in described cradle frame, be fixed with a plurality of grinding heads, described grinding head comprises grinding wheel and polishing motor, described cradle frame is hinged on the vehicle frame of rail grinding machine, between described cradle frame and described vehicle frame, is provided with hydraulic cylinder.
As seen from the above technical solution provided by the invention, the rail grinding machine polishing unit that the embodiment of the present invention provides, because the cradle frame of grinding head is hinged on the vehicle frame of rail grinding machine, between cradle frame and described vehicle frame, be provided with hydraulic cylinder, can control the angle of polishing unit, applicable various rail grinding machines, be used for revising the wavy wearing and tearing of track, wheel track scratch, in correcting, the various steel rail defects that travel on rail and produce due to vehicle such as outer rail inclination and distortion and finishing running surface of wheeltrack, carry out the preventive maintenance of circuit rail.Simple in structure, rotation facilitates, cost performance is high, maintenance cost is low.
Accompanying drawing explanation
The structural representation of the rail grinding machine polishing unit tilting gearing that Fig. 1 provides for the embodiment of the present invention.
In figure: 1-cradle frame; 2-hydraulic cylinder; 3-vehicle frame.
The specific embodiment
To be described in further detail the embodiment of the present invention below.
Rail grinding machine of the present invention polishing unit tilting gearing, its preferably the specific embodiment be:
Polishing unit comprises cradle frame, in described cradle frame, is fixed with a plurality of grinding heads, and described grinding head comprises grinding wheel and polishing motor, and described cradle frame is hinged on the vehicle frame of rail grinding machine, between described cradle frame and described vehicle frame, is provided with hydraulic cylinder.
The two ends of described hydraulic cylinder are hinged with described cradle frame and described vehicle frame respectively.
Described polishing unit is provided with angle of inclination indicating device.
Described polishing unit is provided with angular displacement sensor.
Described hydraulic cylinder is connected with hydraulic lock.
Specific embodiment:
As shown in Figure 1, polishing unit tilting gearing comprises that a polishing unit and two hydraulic cylinders with hydraulic lock form, and the rotating shaft that polishing unit is fixed on vehicle frame by oil cylinder two ends is rotated.When polishing unit arrives set angle, angular displacement sensor provides signal, and hydraulic lock locks hydraulic cylinder, and polishing unit is locked in this angle rail is polished.
Rail grinding machine polishing of the present invention unit tilting gearing, applicable various rail grinding machines, be used for revising the wavy wearing and tearing of track, wheel track scratch, in correcting, the various steel rail defects that travel on rail and produce due to vehicle such as outer rail inclination and distortion and finishing running surface of wheeltrack, carry out the preventive maintenance of circuit rail.Cost performance is high, rotation is convenient, maintenance cost is low.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
