Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings.

3 and 4 are a perspective view and a side view of a heat conduction clamp device according to a first embodiment of the present invention, and FIG. 5 is a mounting view of a heat conduction clamp device according to the first embodiment of the present invention installed on a main rail.

As shown in the drawing, the heat conduction clamp device includes a heat conduction plate unit 100 , a heat insulating material 140 , and a clamp 200 .

The heat conduction plate unit 100 is bent into an inner plate 112 , an upper plate 114 , and an outer plate 116 to accommodate the heating device 200 installed on a stock rail from above. of the holder 110 , a first extension plate 120 extending from one end of the holder 110 in the abdominal direction of the main rail, and a second extending along the slope of the bottom of the main rail from one end of the holder 110 . It is configured to include an extension plate (130).

The holder 110, the first extension plate part 120, and the second extension plate part 130 are preferably made of a material having excellent thermal conductivity and rigidity and elasticity so that the heat of the heating device 200 can be sufficiently well transferred. .

The holder 110 has a structure in which the lower portion thereof is opened. Therefore, the heat conduction plate unit 100 can be inserted while moving from the upper side to the lower side of the heating device 200 . That is, it is possible to easily fasten the heat conduction plate unit 100 to the heating device 200 without any fastening means. And the inner plate 112 of the holder 110 in contact with the abdomen of the main rail is bent inward at a predetermined angle as shown in the figure. It is normally bent inward, and when the heating device 200 is inserted into the holder 110, the heating device 200 is firmly tightened by elasticity, thereby maintaining a stable fixed state.

The first extension plate part 120 is formed to extend to the abdomen direction of the main rail. According to the periodic and repeated movement of the tongue rail that contacts or separates from the main rail, the snow accumulated on the bottom of the main rail rises and accumulates or freezes on the ventral side. in order to remove In the prior art, as shown in FIG. 2, a heating device of a predetermined size is simply attached to the main rail, and snow or ice crystals accumulated on the abdomen side of the main rail cannot be removed. As a result, it is possible to easily remove the snow or ice crystals in the abdomen and bottom of the main rail by cooperating with the first extension plate part 120 and the second extension plate part 130 .

The heat insulating material 140 is provided on the contact surface of the heat conduction plate unit 100 in contact with the main rail. The heat insulating material 140 is for preventing or minimizing heat generated according to the driving of the heating device 200 from being transferred to the main rail side. This is because, when the heat of the heating device 200 is easily transferred to the main rail, it takes more time to melt the snow or ice crystals in the space between the main rail and the tongue rail.

The clamp 300 is a configuration for fixing the heat conduction plate unit 100 to the main rail. The clamp 300 includes a bottom plate 310, first and second

bent parts

312a and 312b extending from both ends of the bottom plate 310, and the main rail bottom extending from the first bent part 312a. a first swash plate portion 314a disposed on one inclined surface of It is composed of a fixing plate portion 316 extending from the 314b and wrapping the upper plate 114 and the outer plate 116 of the holder 110 to fix and support the heat conduction plate unit 100 .

Therefore, when the heat conduction plate unit 100 is installed in the heating device 200 disposed on the main rail, and then the clamp 300 is installed to surround the main rail and the heat conduction plate unit 100, the heat conduction plate on the main rail The unit 100 may be fixed.

In the first embodiment having such a configuration, the heat generated in the heating device 200 according to the driving of the heating device 200 will be transferred to the heat conduction plate unit 100, and further, the heat of the heating device 200 is a heat insulating material Since the transmission to the main rail is blocked or minimized by 140, it is possible to quickly melt snow or ice crystals in the bottom and abdomen regions of the main rail in the space between the main rail and the tongue rail.

6 and 7 are a perspective view and a side view of a heat conduction clamp device according to a second embodiment of the present invention, and FIG. 8 is a mounting view of a heat conduction clamp device according to a second embodiment of the present invention installed on a main rail.

Most of the configuration of the second embodiment of the present invention is the same as that of the first embodiment described above, but only the structure of the heat conduction plate unit 100 for accommodating the heating device 200 installed on the main rail is different. The same reference numerals are assigned to the same components as those of the first embodiment.

That is, as shown in the figure, in the heat conduction plate unit 100 according to the second embodiment, the holder 110 has an inner plate 112 , an upper plate 114 , an outer plate 116 and a lower plate 118 bent to form a space portion ( 119). So, instead of inserting the heat conduction plate unit 100 from above the heating device 200 as in the first embodiment, the second embodiment inserts the heat conduction plate unit 100 through the side of the heating device 200 . will be.

In the second embodiment, the heat conduction plate unit 100 may be installed in the heating device 200 disposed on the main rail, and the heat conduction plate unit 100 may be fixed to the main rail by using the clamp 300 . And since most of the heat generated by the heating device 200 is transferred to the abdomen and bottom regions of the main rail, the snow or ice crystals therein can be melted more quickly.

The heating device applied to the present invention may generate heat using a heating wire or use an induction heating function. In the case of a heating device using induction heating according to an embodiment of the present invention, an inducton device 200a may be mounted in the heat conduction plate unit 100 . At this time, between the induction device 200a and the heat conduction plate unit 100 (ie, the outer plate of the holder), a metal material 400 effective for induction heating may be attached.

In this way, as described above, the heat caused by the induced heating of the induction device 200a is mainly transferred to the heat conduction plate unit 100 only by the heat insulating material, and therefore, the main rail in the space between the main rail and the tongue rail. It will quickly melt snow or ice crystals in the lower and abdominal areas.

Although described with reference to the illustrated embodiments of the present invention as described above, these are merely exemplary, and those of ordinary skill in the art to which the present invention pertains can use various methods without departing from the spirit and scope of the present invention. It will be apparent that modifications, variations, and other equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.

It can be used for rail junctions and track changers to ensure punctuality and safety of the railway system.
