It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best possible way And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention.

Hereinafter, a line run assist system (hereinafter referred to as a "line run assist system") according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 8 attached hereto.

There is a technical feature that the line run assistant device can be provided with heavy equipment for railway maintenance that can be used both on the road and on the railway while being detached from the large heavy equipment having a larger lane than the gauge of the railway.

As shown in FIG. 1, the line travel assisting apparatus includes a line travel cap 100, a detachment means 200, a lifting cylinder 300, and a guide wheel 400.

The line running cap 100 compensates for the gap generated between the tire T and the line R of the heavy equipment H due to the larger diameter of the large equipment H than the gauge of the line R, (H) can be seated on the rail (R), that is, on the rail, and is configured to be fitted to the tire (T) of the large heavy equipment (H).

The line running cap 100 is formed in a cylindrical shape having an inner diameter corresponding to the outer diameter of the heavy equipment tire T and passing through both sides, and the material thereof is made of metal.

The rail running cap 100 having such a structure is fitted on the heavy equipment tire T as shown in FIG. 2 to compensate the gap generated between the heavy equipment tire T and the rail R, The heavy equipment (H) can be raised.

At this time, in a state where the line running cap 100 and the heavy equipment tire T are combined, the friction force between the line running cap 100 and the heavy equipment tire T must be maximized.

This is to prevent the tire T from being idle in the line running cap 100.

To this end, as shown in FIG. 3, a plurality of protrusions 110 are formed on the inner circumferential surface of the line running cap 100 along its circumference.

Since the plurality of protrusions 110 are formed on the inner surface of the line running cap 100 as described above, the frictional force between the rubber tire T of the heavy equipment H and the line running cap 100 can be maximized, It is possible to prevent the heavy-duty tire T from being idle in the cap 100.

At this time, the protrusion 110 may be formed on the inner surface of the line running cap 100 as described above, and a groove (not shown) may be formed to increase the frictional force with the heavy equipment tire T.

As described above, even if the protrusions 110 are formed on the inner circumferential surface of the rail running cap 100, clearances may be generated depending on the degree of wear of the heavy equipment tire T. In order to compensate the clearance, 120 may be further provided.

The air bag 120 may be configured to inflate by injecting air. An air bag for opening the structure using air pressure in the event of an accident involving a person in the structure, for example, an air bag 120 may be used.

The width of the line running cap 100 is not limited and the gap generated between the tire T and the rail R of the heavy equipment is compensated and the extent to which the line running cap 100 can be placed on the rail R It is acceptable if it is.

Further, it is preferable that the line running cap 100 further includes a bent piece 130 as shown in FIG.

This is to prevent the track running cap 100 from being detached from the tire T when the vehicle is running on a track.

That is, even if a clearance is generated between the tire T and the rail running cap 100 due to the formation of the bending piece 130, the bending piece 130 interferes with the side surface of the tire T, So that the line running cap 100 does not come off.

Further, the line running cap 100 may be configured in place of the tire.

6, the rear wheels of the heavy equipment are provided with a pair of two tires T. In the pair of tires T, instead of the outermost tire T, Since the metallic wheels 140 formed integrally are formed to prevent the rail running cap 100 from being separated from the rail and running power directly to the rail running cap 100, the gap between the tire T and the rail running cap 100 It is possible to travel on the track.

At this time, the metal wheel 140 integrally formed with the line running cap 100 is fixed to the outer circumferential surface of the existing wheel by welding in a size corresponding to the tire T, and the wheel is fastened to the existing tire T shaft As shown in FIG.

The detachment means 200 serves to detach the guide wheel 400 to the heavy equipment H and to detach the guide wheel 400 at the front end and the rear end of the heavy equipment H,

That is, according to the present invention, the auxiliary equipment enabling the vehicle to travel on the line R is not always fixedly used in the heavy equipment H but is configured to be detachable so that the heavy equipment H can travel lightly Since it can be installed in other heavy equipment, the efficiency of operation is improved so that other heavy equipment can be used even in the case of heavy equipment failure. Therefore, the structure of the detachment means is important.

At this time, the reinforcing frame 500 is installed in the direction of the heavy equipment H width in the front wheel finishing and the rear wheel finishing of the large heavy equipment H, respectively.
