Ice and snow preventing device of steel track beam

Abstract

The invention relates to the technical field of track traffic, and discloses an ice and snow preventing device of a steel track beam. The ice and snow preventing device comprises heat tracking belts and ice and snow preventing coatings, wherein the heat tracing belts are arranged on the top face of a beam body of the steel track beam, and the ice and snow preventing coatings are arranged on the two side faces of the beam body; the heat tracing belts are used for heating walking face steel plates of the beam body; and the snow preventing coatings are used for preventing ice and snow from being attached to guide face steel plates and stabilizing face steel plates of the beam body. The heat tracing belts are attached to the lower side of the walking face steel plate, and remaining portions of the heat tracking belts are wrapped by a heat insulation layer; and the heat insulation layer is used for reducing heat losses and preventing heat from being transmitted to the interior of the beam body. According to the device, whole-line ice and snow melting of the steel track beam can be rapidly carried out, large temperature stress cannot be generated, safety performance of the device is ensured, and the construction difficulty is simplified.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a steel rail beam anti-ice and snow device. 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 durability of the b...

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 snow-removed. It is not easy to arrange, and it is easy to cause damage to the structure of the beam body; the line is long, and the bridge deck heating and deicing technology currently applied to highway bridges is only suitable for partial bridge decks, and the track beam needs to melt ice and snow along the entire line, which requires overcoming the long-distance energy transmission. question

It can be seen that none of the existing technologies can well solve the operational problems of steel track beams under snowfall weather in winter
