Problems solved by technology

Since the diameter lengths of the two dark nuclei are 2.5mm and 18mm respectively, and they both exist at the bottom of the rail, they are also the particle size of the nuclear flaw that is difficult to detect by the current rail flaw detection equipment (the smallest nuclear flaw that can be detected by the existing flaw detection equipment The particle size is 3mm), the continuous low temperature and large temperature difference in the pipe, the internal stress of the rail increases, resulting in rail breaking accidents
[0004] Track breakages mostly occur in winter and spring, generally from late November to early March of the following year. Track breakages in cold areas are severe in ordinary areas, and most of them occur in the lowest temperature of the day and night from 0:00 to 4:00. Now The processing method requires manual inspection, which requires a lot of manpower

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...

Abstract

The present invention relates to a rail heating and thermal insulating device acting on two parallelly arranged steel rails. A heating and thermal insulating belt is fixed to one side wall of each rail. The heating and thermal insulating belt is successively provided with a wear resistant layer, one insulating layer, a heating layer, another insulating layer and a thermal insulating layer from inside to outside. The rail heating and insulating device is used for heating and thermal insulating of the rails, the temperature of the steel rails in the ice and snow weather is increased, ice and snow are prevented from being attached to the steel rails, train operation can be safer, labor intensity of workers for removing the ice and snow on the steel rails is also largely reduced, and the device is particularly important for rails having combat readiness property. The device is also equipped with a temperature measuring device for obtaining the temperature of the rails at any time, and the temperature of the rails can be automatically controlled by adjusting the temperature.

Description

technical field [0001] The invention relates to the field of rail maintenance, in particular to a rail heating and heat preservation device. Background technique [0002] Rails are the main components of railway tracks. Its function is to guide the wheels of the rolling stock to move forward, bear the huge pressure of the wheels, and transmit them to the sleepers. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. In the electrified railway or automatic blocking section, the rail can also be used as a track circuit. [0003] Congenital quality defects of rails are the main cause of rail fractures. In January 2002, the long rail on the right side of the line broke twice at DK152+573 on the Changtu Line and DK317+450 on the Changtu Line. Since the diameter lengths of the two dark nuclei are 2.5mm and 18mm respectively, and they both exist at the bottom of the rail, they are also the particle size of the nuclear flaw that is difficul...
