Abstract
The invention relates to a snow melting device of a railroad switch, which can fast melt the ice and the snow of switch positions automatically. The snow melting device of the railroad switch is characterized by being started as required by adopting the high-frequency electromagnetic heating principle and fast melting the accumulated snow of closed switch parts, an intelligent controller is connected with an electromagnetic heater through a high-frequency current generator and a high-frequency buried cable, and a temperature sensor is installed inside the electromagnetic heater fastened on the rail waist of a basic switch rail by connecting bolts through fixing holes on the basic railroad switch rail. The fast snow melting device of the railroad switch is conveniently installed without interfering with any other electrical systems of the railroad, can quickly heat and has overtemperature protection function, short work time, high efficiency of thermal energy conversion and snow melting, and obvious energy-saving effect without being influenced external environment climate. When accumulated snow or ice dreg is left in closed switch gaps, the snow melting procedure is started to ensure that the ice and the snow of the switch positions can be fast removed, so that a switch transforming device can be closely attached normally and the railroad transportation is normal.
Description
Technical field
Patent of the present invention belongs to the corollary apparatus of railway transportation facility, relates to a kind of ice and snow that melts deironing way trouble position automatically fast that has, and guarantees that the point tongue turn-out track is normal, the chain fast snow melting device of railroad switch to bit function of signal.
Background technology
In most of area of China, rail transportation system is usually perplexed by ice and snow weather in the winter time, particularly bigger snowstorm, usually since clear the snow untimely or snow removing thoroughly do not cause railway transportation overdue, stop transport, even the person and security incident take place.How in time, safety, economy, remove the particularly accumulated snow at railway switch position of railway reliably, prevent the generation of the malfunctioning phenomenon of changing points device, be that railway traffic transportation system attaches great importance to and insoluble problem always.The snow-removing method that tradition adopts is manually to sweep away snow, though this method clears the snow thoroughly, but existence is wasted time and energy, is influenced vehicle and normally moves, also cause the drawback of personal safety accident simultaneously easily, particularly night and remote districts track switch accumulated snow, be difficult in time remove, the modern railways transportation that this is more and more faster for locomotive speed, the train number frequency is more and more higher is the knurl disease of a safe and punctual operation of influence really.Adopt chemical snow melt, machinery to block methods such as formula snow defence, the snow melt of high pressure air-sweeping type and electrical heating type snow melt at present except manually sweeping away snow in addition, these methods are mostly immature because of technology, installation is numerous and diverse, unreliable, energy consumption is big etc., and many reasons can't be applied on a large scale.Chinese patent ZL200620078348, ZL200520092446 by retrieval, disclosed all is the technical scheme that adopts the electric calorifie installation snow melt, but the common issue with that their exist is: 1, the electric heating tube used of electric calorifie installation snow melt or heat tape are the resistance wire outside and add sleeve pipe and be made, power is little, intensification is slow, need preheating in advance, and stop back several hours at the process of snowing and snow and be in the heating work state always, power consumption is excessive, causes the serious waste of the energy; 2, the electric calorifie installation of all track switches all is to start simultaneously and work basically, has taken sizable power supply capacity, needs the station to enlarge power supply capacity.Thereby the technical scheme of existing employing electric calorifie installation snow melt can not be applied on a large scale.
Summary of the invention
Technical scheme of the present invention has solved above-mentioned defective, purpose provides a kind of high-power fast snow melting device that adopts the high-frequency electromagnetic heating technique, adopt the mode of time-sharing work to start as required and the automatic ice and snow that melts fast except that the track switch position, greatly reduce energy consumption, and need not enlarge the power supply capacity of station.
Fast snow melting device of railroad switch content Description of the present invention:
The present invention relates to a kind of railway switch snow melt solution of melting fast automatically that has except that the ice and snow at track switch position, it is characterized in that: adopt high-frequency electromagnetic heating principle to start and melt fast the accumulated snow of switch closure part as required, be to be connected with electromagnetic heater by high-frequency current generator and high frequency buried cable by intelligent controller, temperature pick up is equipped with in electromagnetic heater inside, electromagnetic heater is to be connected and fixed with connecting bolt by the fixing hole on the railway switch stock rail, place the switch closure part inboard electromagnetic heater, electromagnetic heater is anchored on the web of the rail place of track switch stock rail with connecting bolt.
Electromagnetic heater by: high frequency heat-conducting plate, mounting bracket and temperature pick up are formed.
Mounting bracket is to be made by high temperature resistant and insulation, and one side has groove, is used to embed the high frequency heat-conducting plate, and another side has the round thread hole.
Railway switch device for melting snow of the present invention uses industrial-frequency alternating current as power supply, and power output is adjustable continuously, and the length of electromagnetic heater slightly is longer than point tongue, can adjust its length according to the kind of railway switch.Can reach 100 ℃ through test electromagnetic heater rapid several seconds of heating up; intelligent controller can judge whether the switch closure position has accumulated snow and regulate power output automatically according to the programming rate of electromagnetic heater; if no ice and snow then stops heating; and be provided with temperature protection prevent to heat too high, guarantee in the course of the work switch closure all the position the snow melt deicing reliable rapidly.The installation of electromagnetic heater is to utilize tongue and stock rail to close up the slit of back web of the rail part above-below direction, and fixes to clamp in stock rail web of the rail inboard with connecting bolt, have do not peel, not crackle, not short circuit, the performance of moistureproof resistant to rust, anti-vibration.Convenient for installation and maintenance, can reach more than 10 years application life.
