Description
Technical field
The utility model relates to the railroad rail servicing unit, particularly a kind of railway switch electric heating deicing or snow melting device.
Background technology
The snow that is deposited in after snowing winter between railroad track and the track switch directly influences the flexibility ratio of pulling railway switches, and causes track switch not in place, and potential unsafe factor is arranged, and is the railway systems a great problems.
Traditional railway switch snow removing mode probably has three kinds: manual work is swept away snow, blowtorch snow melting, spade snow removing, i.e. manpower cleaning track switch accumulated snow.Though can remove the accumulated snow at track switch place preferably, have following drawback: 1. personnel employ greatly, and potential safety hazard is big, energy is thrown in big; 2. the equipment use is many, and physical demands is big, and capital consumption is big; 3. the train running on scheduled time rate is low.Other snow removing mode like wind-force snow removing, Snow Agent snow removing etc., also all exists efficient low, has drawbacks such as serious personal safety hidden danger.
A kind of snow melt of track switch efficiently mode that " track switch electric heating device for melting snow " produces to above drawback just.Generally comprise two parts: function monitor part and electric heating assembly part.Wherein the most important thing is the electric heating assembly part, it is directly determining the snow melt effect of device.Present existing track switch electric heating device for melting snow, like " the electrical heating track switch device for melting snow " of the research and development of Tianjin Railway Signal Factory of Chinese Railway signal of communication group, the heater element in its electric heating assembly all is cylindrical or similar columniform electrically heated rods.This type electric heating device is used for outdoor open space snow removing, and is efficient low, relatively poor with its snow removing effect under the constant power.This be because, for confined space, as long as electric heating device heating is arranged, space temperature will raise within the specific limits, if heater element rises to more than 0 ℃ temperature, just there is the ability of melting part snow or ice in this space.But for open space, electric heating device is very little to the temperature rising contribution of open space.Therefore, the ability of the melting of heater element, two aspects that the snow removing ability is decided by it, the one, the area size (as long as heater element can remain on more than 0 ℃ in the snow melt process) that directly contacts with snowfall; The 2nd, the thermal-radiating power in the snow removing position of confirming.
Summary of the invention
The purpose of the utility model be exactly to existing with heater air flow pressure switch rod spare be calandria the track switch snow-removing device intrinsic direct contact snow melt area little; The radiation snow melt irradiation level of non-direct contact is with the technology shortcoming of distance inverse ratio decay, and design provides a kind of technical scheme that adopts the railway switch electric heating deicing or snow melting device of planar heating panel.The said railway switch electric heating of this scheme deicing or snow melting apparatus structure is simple, and handling ease is easy for installation; Long-pending big with the snowfall direct contact surface, strong in the snow removing position heat radiation of confirming, snow melt efficient is high; Snow melt is effective, reduces personnel labor intensity, guarantees to transport safely.
