BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a preferred embodiment of a rod roller with improved anti-vibration performance provided by the present invention will be described with reference to the accompanying drawings.

The rod roller 1 with improved anti-vibration properties provided in the present invention is mainly equipped with heavy iron wheels 2 as a heavy equipment for grounding.

The rod roller 1 is composed of a cocum roller composed of one front wheel and two rear wheels and used for crushing a gravel crush stone or used for a stopping operation, a 2-axis tandem roller having one front wheel and one rear wheel, a 3-axis tandem Tamping rollers that attach the protrusions to the surfaces of the rollers and rollers, and the protrusions are embedded in the voltage layer to break weathered rocks to dissipate the water pressure in the soil.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an outer shape of a load roller having improved anti-vibration characteristics to which the present invention is applied.

The figure shows a cram curler 4 composed of two front wheels and two rear wheels, and the front and rear wheels of the cramp roller are commonly applied to the load roller 1 with improved anti-vibration performance according to the present invention.

FIG. 2 is an exploded perspective view showing a wheel configuration of a load roller with improved anti-vibration performance provided by the present invention, and FIG. 3 is a sectional view of FIG.

As shown in the drawings, the rod roller 1 according to the present invention improves the configuration of the wheel 2 constituting the front wheel or the rear wheel as shown in the figure, and vibrates when the wheel 2 moves along the road surface 1a so as to be prevented from being transferred.

The wheel 2 of the rod roller 1 normally connects the roller 4 to the roller shaft 3 and forms a space 5 on the outer periphery of the roller 4 so as to have an additional load, (5) can be filled with heavy materials (6) such as iron, water, and sand to provide a high load.

In the present invention, the vibration-proofing means 10 is coupled to the roller shaft 3, and the outer periphery of the vibration-proofing means 10 is kept in a state of being closely contacted with the inner surface of the roller 4, And a protection cover 7 is coupled to the side surface of the roller 4 to prevent dust or foreign matter from flowing into the roller shaft 3 to prevent the roller shaft 3 from being damaged .

The vibration damping means 10 includes a wheel 11 fixed to the roller shaft 3 and an anti-vibration member 12 coupled to the wheel 11. At this time, the anti-vibration member 12 is to use a tire widely used in the market, and the tire may be a tube type in which a tube is inserted into the tire or a non-tube type that is used without a tube.

When the anti-vibration means 10 is applied between the roller shaft 3 and the roller 4 as described above, vibration occurs when the roller 4 moves along the road surface in the uneven state, and the vibration is transmitted from the roller 4 side The vibration is absorbed by the anti-vibration member 12 composed of the tire structure and is mostly blocked from being transferred to the vehicle body 1a through the wheel 11 and the roller shaft 3, thereby providing dustproofness.

An air inlet 7a is formed in the protective cover 7 for sealing the side surface of the roller 4, and the air inlet cover 8 is closed.

It is necessary to adjust the air pressure to the anti-vibration member 12 of the tire constituting the anti-vibration means 10 when the air inlet 7a is formed in the protective cover 7 and the air- Can be very useful when there is. That is, when the cover 8 for air injection is detached, the air valve 12a provided on the wheel 11 side is exposed, so that the air pressure of the anti-vibration member 12 can be easily adjusted by injecting or discharging air .

FIG. 4 is a cross-sectional view illustrating a wheel configuration of a load roller having improved anti-vibration characteristics, which is an example in which a plurality of vibration damping means provided in the present invention is applied.

This is applicable to the front wheel of the cramp roller 4 or to the wheel 2 having a large width such as the tamping roller 4 and the roller shaft 3 is positioned on both sides of the roller 4, 3 and the wheel 11 is provided with the vibration preventing means 10 so as to be applicable to the wheel 2 having a wide width.

FIG. 5 is an enlarged cross-sectional view illustrating the structure of a fixing means for fixing the anti-vibration member applied to the present invention.

The vibration-proofing means 10 provided in the present invention provides the vibration-proofing member 12, which is in contact with the inner surface of the roller 4 in a state of wrapping the wheel 11 coupled to the roller shaft 3, And a fixing means (13)

The fixing means 13 includes a stationary ring member 14 located on the roller shaft 3 side and a variable ring member 15 located on the opposite side of the stationary ring member 14.

The stationary ring member 14 is in the form of a donut and is configured to be maintained in a state of being welded or bolted to the inner surface of the roller 4. The variable ring member 15 is donut- And a fixing bolt 16 screwed to the roller 4 is inserted and fixed in the assembly slot 15a.

The variable ring member 15 constructed as described above is assembled so as to be movable in the axial direction and is configured to have a detachable configuration as required. The variable ring member 15 is disposed on the side surface of the vibration-proof member 12 so as to prevent the vibration- The variable ring member 15 is completely separated from the roller 4 and the wheel 11 including the vibration-proof member 12 is separated from the roller shaft 3 So that the dustproof member 12 can be replaced.

When the anti-vibration member 12 is to be replaced, the roller shaft 3 is separated while being supported by a jack, the wheel 11 is separated, and the anti-vibration member 12 is separated from the separated wheel 11 It may be separated and combined.

In the case of using the rod roller 1 having the improved anti-vibration property of the present invention as described above, even if vibration occurs in the roller 4 moving along the road surface in the uneven state as described above, And is transferred to the wheel 11 coupled to the roller shaft 3 in a state in which it is mostly annihilated by the anti-vibration member 12 of the tire constitution constituting the roller shaft 3.

Therefore, it is possible to minimize the vibration transition to the vehicle body 1a to which the roller shaft 3 is coupled, and it is possible to reduce the damage of the vehicle body 1a due to the vibration, the engine damage, and the reduction in ride comfort. In addition, since the vibration of the vehicle body 1a itself is reduced, the riding fatigue can be remarkably improved even if the occupant is working for a long time.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of protection of the present invention should not be limited to the described embodiment, but should be determined by the equivalents as well as the claims that follow.
