Description

  The present invention relates to a heater device for a floor plate of a switch that melts and removes snow that has fallen on the floor plate of the switch.

  For a long time, in order to melt and remove the snow on the switch, Kantera was put under the floor board and the floor board was heated by combustion heat. However, Kantera has the disadvantages that the amount of combustion heat cannot be adjusted due to its structure, and that the combustion part and the tank part are integrated, the fuel capacity is small, and the combustion duration is limited. In place of this Kantera, a heater by constant electricity supply has been proposed, and in order to increase its thermal efficiency, a proposal has been made (in Japanese Utility Model Application No. 60-76101) in which a surface heating element incorporating a heater is installed in the floor plate. However, there is a drawback that the floor plate is formed by cutting out a large hollow portion, and there is a disadvantage that the cost is high, and the floor plate for compensating for the lack of strength is enlarged, and the compatibility with the floor plate of the conventional switch is lost. .

In the ball receiving floor plate of the switch disclosed in Japanese Patent Laid-Open No. 9-195201, the ball receiving portions are scattered all over the surface, so that the accommodation space cannot be secured. Therefore, Japanese Patent Application No. 2002-119826 has been proposed to improve such drawbacks.
Shokai 60-76101 JP-A-9-195201

In Japanese Patent Application No. 2002-119826 proposed by the present patent applicant, in the heating relationship between the heater 3 and the floorboard body 1, it is necessary to reduce the air in the interval between the heater hole 2 and the heater 3 as much as possible in order to increase the heat transfer efficiency. The accuracy of the gap 4 is required. For this reason, although the heat transfer efficiency to the floor board main body 1 increases, since air exists in the space | gap 4, in order to set it as predetermined temperature, the inside of the heater hole 2 becomes as high as 700 degreeC. For this reason, there existed the following faults. First, since the heater nichrome wire burns out in a single period, the life of the heater is short. Secondly, since the SUS material having high heat resistance is used for the heater cover on the outer peripheral surface of the heater, the heater cost increases. Thirdly, since the temperature around the heater is high, the heater hole wall surface and the heater cover are oxidized at high temperature, rust is generated, the heater is fixed, and the heater is difficult to pull out for maintenance. .
The present invention is intended to eliminate these drawbacks and to exhibit the intended effect in Japanese Patent Application No. 2002-19826.

Yes. Then, the ball receiver 16 is separated from the rolling rail holding support portion 14 in the lateral direction transverse to the moving direction of the rolling rail, and the mounting holes 17 are opened to the appropriate number of places at the required intervals. Although the heater hole 18 which arrange | positions an opening part in the end surface of the one end part 11b is cut | disconnected in the center part of the longitudinal direction of the floor board main body 11 which is the middle of those which are spaced apart, for example, it cuts, it is a floor board main body 11 is provided up to the middle of the rolling rail support portion 13, and for example, a heater body 19 in which a heater wire (not shown) is shielded inward is inserted into the heater hole 18, and the outer peripheral surface of the heater body 19 and the heater hole are inserted. An oil 21 that is an example of a heat transfer liquid is put into a gap 20 formed by the inner wall surface of 18, and a sealing fitting 22 is attached to the inlet of the heater hole 18. The sealing fitting 22 and the heater body 19 may be integrally provided in advance.

  Since the heater device 10 for a floor plate of a switch according to the second embodiment of the present invention is as described above, when the heater body 19 is supplied with heat from the power supply line 23 and generates heat, the heater body 19 moves in the moving direction of the switch rail. The heat generation energy is conducted to the floor plate body 11 covering the wall thickness, and from the central portion to the ball receiver 16 of the rolling rail support portion 13 and the rolling rail support portion 14. Since it conducts to the peripheral parts, these parts are efficiently heated, and the snow that accumulates on the upper surface of the floorboard body 11 is efficiently melted.

  Next, the floor plate heater device 24 of the switch of the third embodiment of FIGS. 8 and 9 will be described. The floor plate body 25 has the same structure as the floor plate body 11 of the second embodiment and has a required thickness. The steel plate has a required length and width, and its upper surface is similarly formed from one side to the other side as a fixed rail support portion 26, a rolling rail support portion 27, and a rolling rail support portion 28, and a floor plate body 25. Both end portions 25a and 25b are configured as sleeper fixing attachment portions 29a and 29b. Then, the ball holder 30 can be inserted into the rolling rail support portion 28 so that it can be inserted into the left and right sides, which are transverse to the direction of movement of the rolling rail, at a required interval in a reverse row and into each other. The left heater hole 32a is fitted and arranged in the mounting hole 31 opened as close as possible, and the openings are arranged on the left and right side edges 25c and 25d of the floor plate body 25 outside thereof on the end face of one end 25b.
