Abstract

The invention discloses a railway turnout ground electric heating ice and snow melting system which comprises a power source and a control cabinet and further comprises a plurality of heating devices and an ice and snow detector, and the heating devices are pre-buried in a track base below a turnout rail so that the track base can upwards form a heat radiation temperature field with the hot lower portion and the cold upper portion to the top end of the rail; the ice and snow detector is installed on a mechanical movable part of a turnout. The system has the advantages that the U-shaped heating cable in the track base below the rail forms the temperature field which is hot at the lower part and cold at the upper part from the track base to the top end of the rail upwards, the temperature field is like a sandwich, the system automatically monitors climate change through the ice and snow detector, when snow and ice are accumulated, the temperature of the turnout iron piece is always kept above +2 DEG C, and snow accumulation and icing are prevented at the turnout. And the melted snow water can naturally permeate and run off due to the heat accumulated in the roadbed layer, so that secondary icing cannot be caused.

Description

Technical field:

[0001] The invention relates to the field of ice and snow melting for railway turnouts, in particular to an electric heating ice and snow melting system for railway turnouts. Background technique:

[0002] A turnout is a line connection device that allows locomotives to transfer from one track to another. Slight freezing often makes the line slip, causing the driving wheels of the traction locomotive to idling, making it difficult to effectively increase the traction force, and causing the train to climb uphill. stop accident. The heavy snow cover also makes it difficult for the locomotive crew to confirm the line and watch the signal; if the snow cover is too thick, it will also make it difficult for the train to run. If the switch cannot operate normally, the train will derail. Invention content:

[0003] The purpose of the present invention is to solve the existing problems, and provide a railway turnout geoelectric heating ice and snow melting system....

Examples

Embodiment 1

[0020] Embodiment 1, the geoelectric heat melting ice and snow system of railway turnout, including power supply and control cabinet, also includes several heating devices 1 and ice and snow detectors, said heating device 1 is embedded in the roadbed below the turnout rail 3, so that the roadbed Up to the top of the rail 3, a thermal radiation temperature field 2 is formed, which is hot on the bottom and cool on the top. The heating device 1 includes a heating part 101 and a cold-end junction box 102 connected thereto. The heating part 101 is a MI heating cable, and the MI heating The cable includes a heating core, an inorganic magnesium oxide insulating layer and a stainless steel metal sheath. Since the MI heating cable is a pure resistance heating, and the heat transfer of magnesium oxide is very good, the MI heating cable is heated between its core and the metal sheath. The temperature difference is very small, and can convert electrical energy into heat energy to the great...
