Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an antifreeze heater mount for rails that supports an antifreeze heater that heats the rail head to prevent freezing at the lower corner of the rail head. It is related to.

[Summary of the invention] This invention is made of a metal plate having spring elasticity and is formed into a substantially L-shape, and is supported by the rail by gripping the bottom of the rail with the rail bottom gripping part of the lower part, and the upper part of the metal plate is supported by the rail. By pressing and supporting the antifreeze heater located at the lower corner of the rail head on the lower corner of the rail head using the heater support and urging section, the rail head can be easily kept warm without requiring any special processing on the rail. This is how it was done.

[Prior Art] Conventionally, there has been no example of heating the rail head with an antifreeze heater to prevent freezing.

An object of the present invention is to provide an antifreeze heater mount for a rail that allows the antifreeze heater to be easily supported at the lower corner of the rail head without requiring any special processing on the rail side.

[Means for solving the problems] The structure of the present invention to achieve the above purpose is as follows:
Referring to FIGS. 1 and 3, which correspond to embodiments, the anti-freeze heater mount 5 for rails according to the present invention is formed of a metal plate having spring elasticity into a substantially L-shape. The side part is the bottom part 1 of the rail 1
The upper part rising from the rail bottom gripping part 5A serves as a heater support for supporting the antifreeze heater 4. Recess B
1 and a heater biasing part B2 that elastically presses the antifreeze heater 4 against the lower corner 1B of the rail head.

[Function] Such anti-freeze heater mounting tool for rail 5
is the rail bottom grip part 5A provided on the lower part.
It can be easily attached to the rail 1 by simply fitting it onto the bottom 1C of the rail 1 from below. Further, the anti-freeze heater 4 can be supported by the heater support urging portion 5B provided in the upper portion and easily pressed against the lower corner portion 1B of the rail head for support.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3. As shown in the figure, in this embodiment, a rail 1 is laid on a rail floor 2 and supported by sleepers 3. A pipe-shaped antifreeze heater 4 is disposed at the lower corner 1B of the head 1A of the rail 1 along its longitudinal direction. The anti-freezing heater 4 is constructed by, for example, housing three-phase insulated heating wires in a metal pipe, and star-connecting these insulated heating wires at one end in the longitudinal direction so that power can be supplied only from the other end. or a sheathed heater. The antifreeze heater 4 is supported at intervals in the longitudinal direction at the lower corner 1B of the rail head 1A by the antifreeze heater mount 5 for rail according to the present invention. The lower head corner 1B of the rail 1 to which the antifreeze heater 4 is attached is located toward the lower corner 1B of the opposite side to the side on which the flange 6A of the vehicle wheel 6 moves. In this way, the antifreeze heater 4 can be prevented from being damaged by the wheels 6.

The rail freeze prevention heater attachment 5 is made of a metal plate such as a steel plate having spring elasticity and is formed into a substantially L-shape, and its lower part is fitted into the bottom 1C of the rail 1 from below so as to extend in the width direction. Curved portions A1, A2, and A3 are press-contacted at three points, the top surface at both ends and the bottom surface at the center, to form a rail bottom gripping portion 5A that grips the bottom portion 1C. The upper part rising from the rail bottom grip part 5A is a heater consisting of a heater support recess B1 that supports the antifreeze heater 4 and a heater biasing part B2 that elastically presses the antifreeze heater 4 against the lower corner 1B of the rail head. It is configured as a support urging section 5B. A three-phase electric circuit 7 is laid on the rail floor 2, and power is supplied to the antifreeze heater 4 from a power supply box 8 provided corresponding to the end of the antifreeze heater 4 via a terminal wire 9. .

The antifreeze heater attachment 5 of the present invention is installed intermittently on the rail 1 in advance, for example, as shown in the figure, and then the antifreeze heater 4 is placed along the lower corner 1B of the rail head while each attachment At position 5, the heater support biasing part 5B is separated from the rail 1, and once the heater 4 is positioned at a predetermined position, it is returned to its original position with elasticity, thereby easily fixing the heater 4 to the lower corner part 1B of the rail head with one touch. This allows the installation work of the heater 4 to be carried out very easily and efficiently.

[Effects of the invention] As explained above, the rail antifreeze heater mount according to the invention has a rail bottom gripping part in the lower part, so it can be easily supported by fitting it into the rail bottom from below. In addition, the anti-freeze heater can be easily pressed against the lower corner of the rail head and supported by the heater support and urging section in the upper part. In particular, this fixture uses spring elasticity to attach itself to the rail and to attach the heater, so there is no need to perform any processing on the rail, and it is very suitable for implementation. Furthermore, the installation work of the antifreeze heater can be done efficiently with one touch. Furthermore, this anti-freeze heater fixture can be formed by simply bending a metal plate having spring elasticity, so it can be provided at low cost.
