Abstract
The present invention is a kind of quick de-icing method of hot sand injecting type high-speed train bogie and system, is related to the processing to freeze to accumulated snow on train EEF bogie bogie, is arranged under car body, belongs to vehicular, the accumulated snow that can remove EEF bogie under vehicle at any time freezes.It is solid in the principle that the layers of ice on bogie critical component melts that can will be tied using heat, small sand grains is injected in ice using high-speed jetting devices, ice sheet is broken into honeycomb, since sand grains carries heat, the heat of sand grains can directly melt ice.The speed of ice-melt is fast, and effect is good.Compared with the mode that tradition water melts, water can only act on ice sheet surface layer, and the micro- sand of high speed can inject ice sheet certain depth, by the fast melt from level to level that freezes.
Description
Technical field
The present invention relates to the processing techniques to layers of ice on train bogie.
Background technique
As the increasing of high-speed EMUs is started in northern China severe cold area and other ultralow temperature areas, high speed is arranged
When cold winter is run, environment wind and snow and route accumulated snow will lead to train bogie region and the icing of large area accumulated snow occurs vehicle,
Bogie key position has serious accumulated snow to freeze, and brings hidden danger to bullet train safe operation, while also increasing railway inspection
Accomplish this.
For bullet train in winter wind and snow environment operational process, the snowflake for generating train parting entrainment can enter bogie area
Domain, the snowflake that track section raises can also enter and be attached under vehicle on EEF bogie critical component, and bogie regional structure is complicated,
Accumulated snow not only will form icing, some positions the bogie heater element the effects of under can be melted into water, then quickly form
Ice, reciprocating finally will form biggish ice sheet or ice cube.The accumulated snow and ice cube of corresponding position will lead to compressional movement, resistance
Hinder each component proper motion of bogie, not only breaks up truck components, also reduce its maintenance reliability.Also there be such ask in foreign countries
Topic, therefore, the accumulated snow ice formation issues of removing of high-speed train bogie are all that domestic and international railway relevant departments are of interest all the time
Emphasis.
Some clearing ice technologies were once studied by foreign countries, if foreign countries have using injection mixing water or mixed liquor technology, also there is utilization
The clearing ice technology of gas is discharged in air-conditioning system, and modern architecture in Japan train is used and generated between brake disc and brake lining by slight friction
Heat, melt the technology of attachment ice and snow, also " spraying is anti-using there is the surface for spraying in advance similar to japanning for the EMU in China
The technologies such as jelly " and " blowing is removed and snowed " that utilizes vehicle-mounted compressed air.Alleviate high and cold ice and snow weather bogie in order to more efficient
Accumulated snow ice formation issues, it is ensured that EMU safety, clearing ice technology is also among further research.
Layers of ice be it is harder, water spray can only play the role of the surface layer of icing slight, need to spray many water, and water
As soon as arriving the surface of ice, fall immediately.Under cold climate conditions, excessive water will make track section have more
Ice.
Summary of the invention
Present invention aims at a kind of efficient deicing mode is found, direct deicing is realized, quickly solve bogie accumulated snow
Ice formation issues, it is ensured that EMU safety, the present invention, which discloses one kind and takes the micro- sand injecting type high-speed train bogie of heat, quickly removes accumulated snow

Specific embodiment
Technical solution of the present invention is described further below in conjunction with drawings and examples.
Present invention aims to be injected in the ice sheet on train bogie with the small hot sand grains with heat, immediately
Ice is just broken into honeycomb, the heat of hot sand directly melts ice sheet.
For the compartment of high-speed rail train, car body is located at top, and bogie is located at lower part as EEF bogie, it is contemplated that
There is under vehicle sufficient installation space, the device in this system is hung below car body by hanging bar, and also suspended is fixed
In the suitable position of bogie.
As shown in Figure 1, sand reservoir box 3 for storing small sand grains, hangs bar 1 by left sand reservoir box and right sand reservoir box hangs bar
7 hang, and hang and are installed in car body lower plate, bolt can be used and fix, and hang pole length to reduce, can also be fixed on steering
The suitable position of frame.Sandbox sand inlet 5 and sandbox recycling sand entrance 2 are provided at the top of sand reservoir box 3.It can add from sandbox sand inlet 5
Enter new sand grains, sandbox sand inlet 5 has the cover board that can be started；Sandbox recycles sand entrance 2 and recycles for subsequent sand grains.Heating tape
4 use flexible heater band, and for heating to sand reservoir box 3, heating tape 4 uses two or more, and connects vehicle power supply and obtain
To power supply.
Sandblasting connecting tube 8 is connected to one end of sand reservoir box 3, and positioned at the lower right of sand reservoir box 3, position is hung with sand reservoir box
Hanging rod 7 is staggered, and link position can refer to the reserved connection hole site below 3 other side of Fig. 2 sand reservoir box and be configured (this side
Reserved connection hole site, can block with aperture and with screw plug).
Since train carries cylinder, directly quote, so sandblasting wind sand mixer 10 is connected by sandblasting high-pressure blast
Pipe 9 is connected to on-board high-voltage wind, is connected to sand reservoir box 3 by sandblasting connecting tube 8.10 right end of sandblasting wind sand mixer installs valve
11, hose 12 is connected on valve 11, the right end of hose 12 installs nozzle 14.Micro- sand grains is in sandblasting wind sand mixer 10, by height
It presses wind to drive, flows to nozzle 14 by hose 12, the size of injection intensity is adjusted by valve 11.It is in order to can using hose 12
To adjust the position of nozzle 14, the adjustable multiple positions of injection.Nozzle system is hung bar 13 with nozzle and is hanged, and hangs and installs
In in car body lower plate, bolt can be used and fix, hangs pole length to reduce, the suitable position of bogie can also be fixed on.
Micro- sand grains, can be with using particle made of proprietary material, polytetrafluoroethylene (PTFE) or PTFE base solid lubricant
Serve as the preferable solid lubricant of effect.
Micro- sand grains can melt icing immediately, and the water meeting flow down containing sand grains can also be fallen down, even if falling in orbit
Also not related, the micro- sand grains used originally is exactly a kind of solid lubricant that effect is fairly good, so micro- sand grains can use
Particle made of proprietary material, polytetrafluoroethylene (PTFE) or PTFE base solid lubricant etc..
But in order to be recycled, this system has added sand grains recyclable device, which includes back the mixing of sand wind sand
Device returns sand collection bucket 16 and filtration members, is collected using sand collection bucket 16 is returned to micro- sand grains.It returns in sand collection bucket 16 and was equipped with
Filter, can filter out ice water, and micro- sand grains is only left in bucket.Returning sand collection bucket 16 uses back sand collection bucket hanging bar 17 to hang.
Hanging bar 17 is installed in car body lower plate, and bolt can be used and fix, and is hung pole length to reduce, can also be fixed on bogie
Suitable position.
It returns sand collection bucket 16 and returns between sand wind sand mixer 19 and connected by returning sand connecting tube 18, it is mixed in sand wind sand to return sand
It in clutch 19, is driven by high-pressure blast, flows to sandbox recycling sand entrance 2 by recycling sand pipeline 6.Sandbox recycling sand entrance 2 is equipped with
One stripe board that can be extracted out can block recycling sand and enter sand reservoir box 3 when not extracting out, play the role of closed, and when extraction can
To allow recycling sand to enter sand reservoir box 3.It returns sand high-pressure blast connecting tube 15 and connects on-board high-voltage wind, and is direct from the cylinder on train
Reference.
