Turnout snow melting and anti-icing structure and method

Abstract

The invention relates to the field of rail transit turnout anti-icing, and discloses a turnout snow melting anti-icing structure and method, the turnout snow melting anti-icing structure comprises a railway turnout provided with a plurality of sleepers, and the railway turnout is provided with an integrated cabinet, a distribution pipeline, a plurality of spraying assemblies and a plurality of support modules; the integrated cabinet is connected with the distribution pipeline through a conveying pipeline; the distribution pipeline is connected with the plurality of spraying assemblies; the support module is located in the gap between every two adjacent sleepers and used for fixing the spraying assembly and preventing a track circuit of the railway turnout from being short-circuited. A modular design is adopted, and the integrated cabinet integrates the functions of liquid storage, control, pumping and the like and is suitable for snow melting and ice preventing operation of various railway turnouts. Track insulation and train running safety space are guaranteed through the support module, in addition, by spraying the anti-icing liquid, the snow melting and anti-icing effects are achieved, turnout running safety is guaranteed, faults are reduced, and the snow and ice removing operation pressure of personnel is reduced.

Description

technical field [0001] The invention relates to the field of anti-icing of rail transit turnouts, in particular to a snow-melting anti-icing structure and method for turnouts. Background technique [0002] As the core device of railway, turnout directly affects the safety of railway vehicles. In snowy weather in winter, turnouts often fail due to snow and ice. The disclosed snow melting and anti-icing methods include electric heating, gas heating, hot water heating, manual cleaning, etc. Currently, the widely used snow melting and anti-icing methods for turnouts are mainly electric heating and manual cleaning. [0003] The heating power of the gas heating method is large, and complex gas pipelines need to be laid on the railway, which is very dangerous. Once the gas leaks, it is very easy to cause fire and explosion. The hot water heating method needs to lay pipes, the structure is too complicated, and the end pipes are easy to freeze. The widely used electric heating met...

Problems solved by technology

[0003] The gas heating method has a large heating power, and complex gas pipelines need to be laid on the railway, which is very dangerous. Once the gas leaks, it is easy to cause fire and explosion

The method of hot water heating needs to lay pipes, the structure is too complicated, and the end pipes are easy to freeze

The widely used electric heating method cannot cover the bottom of the tip rail and the basic rail, the head of the basic rail and the tip rail, the transfer machine, the connecting rod and other parts, and these parts are prone to snow accumulation and icing

Whenever it snows, the above parts need to be manually cleaned and deiced, which consumes a lot of manpower
