Abstract

The utility model discloses an electrothermal sliding bed plate which is designed for electrothermal snow removing device of railway track switch. The utility model is characterized in combining heating wire and sliding bed plate together; the utility model enhances contact area of the heating wire and the sliding bed plate so as to get working temperature of electrothermal sliding bed plate through reducing the using temperature of the heating wire; and the utility model is provided with a plurality of subsidiary wire with the aim to reach the aim of bringing convenience to repair or even free of repair. The utility model can lengthen the service life of the electrothermal sliding bed plate and lower the cost of repairing and maintaining.

Description

The electric heating slide plate

Technical field

The utility model is a kind of electric heating slide plate that aims at the design of railway switch snow-removing device.

Background technology

The electric heating slide plate that present domestic railway switch snow-removing device uses is to bore a slotted hole in common slide plate, puts into electrothermal tube and heats to slide plate, reaches the snow removing purpose.But in use also there are a lot of problems:

1, is blind hole owing to what in slide plate, bore,, be difficult to ensure the quality of products, and the electrothermal tube heating area is little, could guarantee the snow melt temperature that slide plate is required when only being operated in 1000 ° so electrothermal tube can only cause its processing difficulties by the single head lead-in wire.Heating wire under such high temperature in the electrothermal tube can produce aging distortion, in addition train by the time high vibration that produces, be easy to cause faults such as electrothermal tube leaks electricity, short circuit.

2, because the electric heating slide plate is the series connection use, the damage of a heating tube will cause one group of track switch to lose the snow removing function.Bad heating tube is got to come out and will the electric heating slide plate be scrapped, and maintenance is difficulty quite.

Summary of the invention

In view of the problem that above-mentioned prior art exists, the purpose of this utility model provides a kind of electric heating slide plate.

The technical solution of the utility model is no longer to adopt electrothermal tube heating slide plate, but heating wire and slide plate are made one.Except that main heating wire was housed, other was equipped with the standby silk of paying, and will concentrate heating to change dispersed-heated into and reach the snow melt purpose.

Owing to heating wire and slide plate are made one, and have a pair heating wire, make the effect that the utlity model has antidetonation and convenient for maintaining.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: 1 slide plate, 2 rectangular channels, 3 dresses are main pays the groove of heating wire, 4 pairs of heating wire wire holes, 5 main heating wire wire holes, 6 zero line wire holes, 7 zero lines, 8 zero line grooves.

The specific embodiment

A kind of electric heating slide plate of the utility model, common slide plate 1 is processed the groove 3 of a rectangular channel 2, the main pair heating wire of dress and pays heating wire wire hole 4, main heating wire wire hole 5, zero line wire hole 6, then in the heating wire and common zero line embedding groove separately with the tape insulation layer, and draw by each lead-out wire hole, refill that a cover plate is fixing to get final product.

Claims (1)

1. an electric heating slide plate is characterized in that, the main silk of heating wire, standby paranema and zero line are embedded in the slide plate, and it is whole to become a heating.
