Description
Technical field
The utility model relates to a kind of rail grinding machine for grinding rails, relates 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; due to reasons such as dynamic action, natural environment and the quality of rail own of train; often can there is hurt situation in rail; as the phenomenon 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.
Utility model content
The purpose of this utility model 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 purpose of this utility model is achieved through the following technical solutions:
Rail grinding machine grinding head vertical lift device of the present utility model, comprise polishing unit, described polishing unit comprises cradle frame, in described cradle frame, multiple 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.
The technical scheme being provided by above-mentioned the utility model can be found out, the rail grinding machine grinding head vertical lift device that the utility model embodiment provides, owing to realizing the vertical movement of parallel-crank mechanism control grinding wheel by cylinder, simple in structure, low cost of manufacture, reliable operation, design are ingenious, can meet the needs of rail grinding train polishing unit.

Described riser is provided with baffle plate, and described cradle frame is provided with upper stroke switch.
The bottom of described riser is provided with position-limited wheel.
Specific embodiment:
As shown in Figure 1 and Figure 2, parallel-crank mechanism comprises: two fixed ends of upper and lower U-shaped arm connect cradle frames), two movable end connection boards composition parallelogram sturcutres.Upper U-shaped arm and lower U-shaped arm are around the U-shaped arm axle rotation of fixed end, and upper U-shaped arm and lower U-shaped arm movable end can limit the rotation of riser, only retain riser and vertically move.Air cylinder driven parallel-crank mechanism is realized the vertical lifting of grinding wheel and decline.
As shown in Figure 1, parallel-crank mechanism can realize vertical upper and lower, move left and right.
As shown in Figure 2, comprise grinding wheel, polishing motor, parallel-crank mechanism, cylinder etc.Cylinder is connected and fixed by cylinder Connection Block, bolt and parallel-crank mechanism.Polishing motor is connected and fixed by the riser of bolt and parallel-crank mechanism.
Rail grinding machine grinding head vertical lift device of the present utility model is applicable to the polishing unit of most of rail grinding machines.Realize the vertical movement of parallel-crank mechanism control grinding wheel by cylinder, simple in structure, low cost of manufacture, reliable operation, designs ingeniously, can meet the needs of rail grinding train polishing unit; Between parallelogram member, be face contact, it is little that unit area is born pressure, can carry large load, is convenient to lubricate, and weares and teares little.Member contact surface is the face of cylinder, easily processing and manufacturing; Cylinder is taking air as working media, and convenient sources, is conducive to protection of the environment; Being swift in motion of cylinder, reaction is fast, safeguards simply, is difficult for stopping up.
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.
