It is energized in cable.
Pre-buried heating steel pipe in steel reinforced concrete combined track beam end face concrete, being installed with cable in heating steel pipe, can produce kelvin effect after energising, in heating steel pipe, temperature raises, heating steel pipe release heat is transferred to beam body surface by concrete, it is achieved heating the melting road surface ice and snow to running face.Concrete has certain capacity of heat transmission, and during heating steel pipe electrified regulation, heat can comparatively fast be delivered to concrete surface, and ice-melt snow is effective.And, after running face snowmelt, water can to two side inflow spigot surfaces with junction steel plate composition rhone, and weld heating steel pipe on junction steel plate, steel plate heat conductivility is better, and heat can quickly make whole tank heat up, and ensures that flowing water will not freeze again.
On the other hand, this ice-melt snow device can promote the normal operation of ice and snow weather lower railway beam, has again relatively low cost, has obvious social benefit.
Next multiple embodiments are used to be described in detail:
A kind of steel reinforced concrete combined track beam heating steel pipe ice-melt snow device, such as Fig. 1, shown in 2, comprising: the kelvin effect heating assembly being arranged in steel reinforced concrete combined track beam end face concrete 1, this kelvin effect heating assembly includes the cable 5 of traverse in many heating steel pipes 4 and self-heating steel pipe 4, and cable 5 passes along the bearing of trend of heating steel pipe 4.Cable 5, by connecting from becoming loop or utilizing heating steel pipe 4 to reflux, is connected with single-phase alternating current in cable 5.Producing kelvin effect after cable 5 energising, make heating steel pipe 4 generate heat, heating steel pipe 4 has certain heat conductivity.Heating steel pipe 4 is discharged heat and is transmitted rapidly by concrete, it is achieved heating the melting road surface ice and snow to running face.Because steel heat conductivity is relatively big, during heating steel pipe 4 electrified regulation, heat can quickly be delivered to concrete and make beam body surface comparatively fast heat up, and ice-melt snow is effective.And, beam body adopts the scheme that steel combine with concrete, and concrete has good coefficient of friction, ensures that under sleety weather, wheel not easily skids.
Heating steel pipe 4 has good durability, generally need not change.Steel duct is worn cable 5 and is produced kelvin effect and make heating steel pipe 4 generate heat.Cable was both played a protective role by heating steel pipe 4, can facilitate again the location of cable 5, installation and replacing.
In some technical schemes, in order to promote the uniformity of heating, and the synchronous effect of heat transmission, all heating steel pipes 4 are equidistantly evenly arranged in the plane being parallel to steel reinforced concrete combined track beam end face concrete surface 1, thus the heat produced also reaches to be uniformly distributed, and, heat transmits from same plane to steel reinforced concrete combined track beam end face concrete surface 1 surface simultaneously, is close to and arrives simultaneously.
In other technical scheme, consider that the running face snowmelt of track girder flows through side and can again freeze, therefore, in the rhone that running face snowmelt is formed to two side inflow spigot surfaces 2 and junction steel plate 3, weld heating steel pipe 4 on junction steel plate 3, heating steel pipe 4 and filling heat-conducting daub 6 in the gap of junction steel plate 3, increase its heat transfer area.Steel plate heat conductivility is better, and heat can quickly make whole tank heat up, and ensures that flowing water will not freeze again.
In order to produce kelvin effect, heating steel pipe 4 is hollow seamless steel pipe.
When heating steel pipe 4 is installed with cable 5, after cable 5 is connected with single-phase alternating current, skin-effect electric heating can be produced.But single-phase alternating current is when cable 5 is by heat tracing tube wall (i.e. heating steel pipe 4), under the effect of kelvin effect and kindred effect, electric current is not uniformly flow along tube wall, but concentrate on heat tracing pipe endosexine and pass through, under the effect of tube wall resistance, by current heating, meet the needs of steel reinforced concrete combined track beam electric tracing (heating).
By adopting electric tracing (heating) mode, it is possible to make beam body surface temperature raise, make the ice dissolution in train operation track girder face, reach straddle-type monorail track traffic and adapt to the purpose of operating environment under low temperature icy conditions.
It is three-phase electricity based on conventional electricity consumption, in use needs to be converted into single-phase electricity, and the length of track girder is different, it is necessary to the magnitude of voltage of heating is also different, and track girder is more long, and magnitude of voltage is more high；Track girder is more short, and magnitude of voltage is more low.Therefore, steel reinforced concrete combined track beam heating steel pipe ice-melt snow device is also provided with transformator, and transformator heats required voltage value according to steel reinforced concrete combined track beam and carries out the voltage conversion of relevant voltage value.
Steel reinforced concrete combined track beam heating steel pipe ice-melt snow required voltage value can be manually set based on experience value, can also work out and carry out automatization's adjustment for program, comparatively speaking, automatization adjusts and more saves manpower, and also to set more accurate simultaneously, based on this analysis, ice-melt snow device is also provided with control equipment, control equipment is connected with transformator, and control equipment for determining the magnitude of voltage of single-phase alternating current according to predetermined manner, and magnitude of voltage is sent to transformator.
Cable is concatenated by many roots cable；The rosette concatenating two root cables is arranged on the bent cap of steel reinforced concrete combined track beam.Steel pipe walks out downwards beam body at beam-ends, arranges rosette on bent cap, by rosette, the heating cable series connection of every beam is got up.
In order to utilize above-mentioned steel reinforced concrete combined track beam heating steel pipe ice-melt snow device to carry out ice-melt snow process, it is necessary to start the layout of corresponding component when prepared by steel reinforced concrete combined track beam.Therefore, ice-melt snow method can trace back to the preparation of steel reinforced concrete combined track beam, and therefore, concrete step is:
Step 101, in the preparation process of steel reinforced concrete combined track beam, is embedded into heating steel pipe in steel reinforced concrete combined track beam end face concrete；
Step 102, reserved rosette installation position on the bent cap of steel reinforced concrete combined track beam；
Step 103, after the erection of steel reinforced concrete combined track beam puts in place, penetrates cable in heating steel pipe；Cable can pass through to connect from becoming loop or utilizing heating steel pipe backflow；
Step 104, is energized in cable
Skin-effect electric heating is produced, it is achieved heating function after energising.
