Embodiment Construction
[0024] like Figure 1-2 As shown, a rail heating and heat preservation device described in the embodiment of the present invention acts on two parallel rails 1. The side walls of the rails 1 are pasted with heating and heat preservation tapes. A felt layer 2, a first insulating layer 3, a heating layer 4, a second insulating layer 5 and an insulating layer 6 are provided; both the first insulating layer 3 and the second insulating layer 5 are insulating rubber layers, and the insulating layer 6 For polyester fiber layer.
[0025] The heating layer 4 includes a resistance sheet, and both ends of the resistance sheet are provided with metal connectors 7 for connecting wires, and the metal connectors 7 are respectively connected to an external power supply 8 to energize and heat the resistance sheet. The external power supply 8 is connected to the control device 9 to control the opening and closing and temperature of the resistor sheet.
[0026] The rail 1 is also provided with...
