Ice and snow melting device for steel track beam

Abstract

The invention relates to the technical field of track traffic, and discloses an ice and snow melting device for a steel track beam. The device comprises a top surface heating strip arranged on the top surface of a beam body of the steel track beam, and side surface heating strips respectively arranged on the two side surfaces of the beam body, wherein the top surface heating strip is used for heating a steel plate on a walking surface of the beam body; the side surface heating strips are used for heating a steel plate on a guide surface and a steel plate on a stable surface of the beam body; the top surface heating strip is bonded with the lower side of the steel plate on the walking surface; the side surface heating strips are respectively bonded with the inner sides of the steel plate on the guide surface and the steel plate on the stable surface; and the top surface heating strip and the side surface heating strips are respectively wrapped with thermal insulating layers for reducing the loss of heat and transferring the heat to the internal of the beam body. The device can quickly and totally melt ice and snow on the steel track beam without generating greater temperature stress, so that the safety performance is guaranteed, and the effects of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an ice and snow melting device for steel rail beams. Background technique [0002] During the operation of straddle-seat rail transit in cold regions in winter, because ice and snow cover the running surface of the track, the friction between the rubber wheel and the track is reduced, which hinders the control of the train and easily causes problems such as train outage and delay. At present, the ice and snow melting technologies applied to straddle rail transit mainly include: [0003] 1. The vehicle is equipped with snow removal brushes. This method is more suitable for thin snow and uniced conditions, but the removal effect and efficiency for thicker snow and surface ice are very low. [0004] 2. Spray deicing agent. Although this method can effectively melt ice and snow, the deicing agent generally has strong corrosiveness, which has a certain impact on the dur...

AI Technical Summary

Problems solved by technology

Although this method is relatively simple, the location of the track beams is high, people are more dangerous during the snow removal process, and it takes a certain amount of time to clear the snow, which will still cause delays to train operations

[0006] In addition, the bridge deck heating ice and snow melting technology used in highway bridges is not suitable for steel track girders

Steel track beams have different characteristics from other bridges: the heating area is large, and the top and sides of the beam body need to be sno...
