Embodiment Construction

[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The purpose of the present invention is to use the tiny hot sand grains with heat to spray into the ice layer on the train bogie, immediately the ice will be made into a honeycomb shape, and the heat of the hot sand will directly melt the ice layer.

[0022] For the compartment of a high-speed rail train, the car body is located at the upper part, and the bogie, as the running part, is located at the lower part. Considering that there is sufficient installation space under the car, the devices in this system are hung under the car body through the hanging rod, which is also It can be hung and fixed on the proper part of the bogie.

[0023] Such as figure 1 As shown, the sand storage box 3 is used to store tiny sand grains. It is suspended by the left sand storage box suspension rod 1 and the right sand storage box susp...

Abstract

The invention provides a hot sand jet type high-speed train bogie rapid snow removing and deicing system and method, relating to the treatment of snow and ice on the bogie of train running part, whichis arranged under the car body and belongs to the vehicle-mounted type, and can remove snow and ice on the running part under the car at any time. Based on the principle that the ice layer which is fixed on the key parts of the bogie can be melted by using heat, the fine sand particles are sprayed into the ice by a high-speed spraying device, and the ice layer is beaten into a honeycomb shape. Since the sand particles carry heat, the heat of the sand particles can directly melt the ice. Ice melts quickly and effectively. Compared with the traditional way of water melting, water can only act on the surface of the ice, and high-speed fine sand can be injected into the ice at a certain depth, ice layer by layer will melt quickly.

Description

technical field [0001] The invention relates to the processing technology for the ice layer on the train bogie. Background technique [0002] With the increasing number of high-speed EMUs operating in severe cold areas in northern my country and other ultra-low temperature areas, when high-speed trains are running in cold winter, the environmental wind and snow and snow accumulation on the line will cause large areas of snow to freeze in the bogie area of ​​the train. There are serious snow and ice in the parts, which brings hidden dangers to the safe operation of high-speed trains, and also increases the cost of railway maintenance. [0003] During the operation of high-speed trains in the winter wind and snow environment, the snowflakes entrained by the train wind will enter the bogie area, and the snowflakes raised in the track section will also enter and adhere to the key components of the running part under the train. The structure of the bogie area is complex, and the a...
