Anti-icing box-shaped rail beam

Abstract

The invention discloses an anti-icing box-shaped rail beam. The device comprises a track beam cross beam and a track beam vertical beam which are arranged in a T shape; a heating cable is arranged at the joint of the track beam cross beam and the track beam vertical beam, the heating cable is laid along the rail beam cross beam, and the heating cable is fixed with the rail beams through a fixing support; the fixing support are L-shaped, and the two ends of the fixing support are respectively connected with the rail beam cross beam and the rail beam vertical beam. According to the anti-icing box-shaped rail beam, the heating cable can be self-heated after being electrified, the track is indirectly heated through heat radiation, the temperature of the heating cable can reach 70 DEG c, the heat of the heating cable can be rapidly transferred to the rail beam in a heat radiation mode in a low-temperature environment, so that the temperature of the rail steel beam can be rapidly increased, the rainwater on the rail surface can be prevented from being frozen; the temperature sensor is arranged, so that the heating condition of the rail can be monitored in real time; meanwhile, the corrosion-resistant coating = of the damaged rail steel beam can be prevented from being damaged due to overhigh temperature.

Description

technical field [0001] The invention belongs to the field of track structure design, in particular to an anti-icing box-shaped track beam suitable for straddling monorail vehicles. Background technique [0002] The icing of the rail surface of the straddle-type monorail vehicle is a worldwide problem, and there is no good solution at present. From our actual project experience, there are two types of track icing. The first is that after a whole night, there is a relatively thick layer of thick ice on the rail surface that sticks to the rail surface. This kind of ice is characterized by hardness. It is high, the ice layer is thick, and it is glued to the track as a whole, so it is difficult to knock it off with a hammer. The second is that after the ice on the rail surface is removed, the weather is relatively cold and humid, and a very thin layer of ice is formed on the rail surface immediately after a few minutes. For vehicles, as long as there is ice on the rail surface,...

Problems solved by technology

[0004] In order to solve the problem in the background technology that the heating area of ​​the track beam is small and cannot meet the long-distance heating anti-icing problem, the present invention proposes an anti-icing box-shaped track beam to solve the problem that the box-shaped track beam is easy to freeze in a low temperature environment , resulting in the situation that the vehicle skids and stalls and cannot run
