Abstract
The utility model discloses an electric heating snow remover for railway switches. A slide plate below a railway switch rail is taken as a heating body, and an electric heater is arranged in the slide plate. When snow falls, snow covers on the switch can be removed by switching on electricity. The utility model is safe and timely, and can save manpower and expense.
Description
The utility model relates to a kind of heater element, especially a kind of railway switch electric heating snow plough.
In background technology, railway switch is made up of with tongue that can relative each stock rail clutch a pair of stock rail.Be lined with slide plate between stock rail, tongue and the sleeper, tongue can slide and the stock rail clutch thereon.In the winter time, meet snowy day,, and make tongue can not lean on close stock rail to cause track switch malfunctioning because of tongue and stock rail have accumulated snow between branching off.On-the-spot cleaning accumulated snow way is that establishment officer's cleaning track switch is gone up accumulated snow, and its shortcoming is instrument of sweeping away snow and the expense expenditure of need purchasing of manually sweeping away snow, and maximum deficiency is manually to sweep away snow can not accomplish to sweep away snow while snowing and have unsafe factor.
The utility model purpose is to avoid above-mentioned deficiency and the railway switch electric heating snow plough that can in time clear the snow when a kind of snowing is provided.
The utility model purpose is achieved in that railway switch electric heating snow plough is that slide plate below the track switch rail is a calandria, is equipped with thermoelectric heating device in slide plate, and thermoelectric heating device is connected with an electric control box by lead.As required, tongue and stock rail by near several groups of slide plates in lay thermoelectric heating device, removing accumulated snow to reach in certain area.The control circuit of thermoelectric heating device has the phase failure, get an electric shock protective device and devices such as electric leakage, short circuit, to guarantee safety in the use, timely.Electric control box is placed in track switch and guards in the room on duty, and a chance is snowed, and energising gets final product, and slide plate is heated, and the accumulated snow on the track switch melts while falling and evaporates, and realizes the electric heating snow removing.
The utility model advantage and good effect are: 1. clear the snow in time.With snowing with energising, clear the snow at any time, thoroughly solved between point tongue and the stock rail and tongue prodelta clay snow and cause the not close card of point tongue, influence the locking problem.2. small investment, saving manpower, minimizing expense are paid.This snow plough is simple in structure, and maintenance, easy to maintenance need not to concentrate that personnel sweep away snow, the outfit instrument.3. safety clears the snow.Can accomplish on the railway line that nobody clears the snow, overcome tactics of human sea in the past and swept away snow to the influence of vehicular traffic and jeopardize personal safety.
Fig. 1 is the utility model structure diagram.
Fig. 2 is that railway switch is arranged and electric control schematic diagram.
Referring to Fig. 1, the electric heating snow plough is made of slide plate 1 and peace thermoelectric heating device 3 within it.Slide plate 1 is a slabbed construction, is drilled with centre bore 2 in the middle of it, and a thermoelectric heating device 3 is installed in the centre bore 2, and there are terminal stud 4 and over cap 5 in its outer end.Thermoelectric heating device 3 is a standard component, but its characteristics dry combustion method.
Referring to Fig. 2, railway switch is made of the stock rail 7 and the tongue 8 of pad on sleeper 6, and slide plate 1 pad is under stock rail 7, tongue 8.As required, select the slide plate 1 of some, in each slide plate 1, lay a thermoelectric heating device 3.For guaranteeing Electrical Safety, an electric control box 10 is arranged between switch 9 and thermoelectric heating device, phase failure protector 11 and earth leakage protector 12 are arranged on it.Per two slide plates, 1 a shared phase failure protector 11 on the same sleeper 6.Indicator lamp 13,14 is used for warning the phase failure and electric shock, electric leakage, short circuit respectively, so that can in time find place under repair and change components and parts, guarantees that snow plough reaches normal snow removing effect.Indicator lamp 15 is used to refer to normal condition.Button 16 is for test is got an electric shock, the short circuit button, and button 17 is test electric leakage button, ground connection button, and button 18 is for recovering the operate as normal button, and the The whole control device has the phase failure, electric shock, electric leakage, short-circuit protection function, to guarantee Electrical Safety.Also with radiator valve, control slide plate 1 temperature is between 10-15 ℃, to accomplish power-saving running on electric control box 10.
During snowfall, personnel on duty close a floodgate power control switch and power, by electric leakage, electric shock, phase failure short circuit, ground connection control button, whether the test earth leakage protector operate as normal, and by recovering the operate as normal button, snow plough is started working after the operate as normal, switched on about 1 hour, slide plate 1 temperature can reach 15-20 ℃, at this moment gauge tap is converted to the constant temperature position, keeps the snow plough operate as normal.
Claims (2)
1. a railway switch electric heating snow plough is characterized in that its slide plate below the track switch rail is a calandria, and thermoelectric heating device is installed in slide plate, and thermoelectric heating device is connected with an electric control box by lead.
2. according to the described railway switch electric heating of claim 1 snow plough, it is characterized in that being equipped with on the electric control box earth leakage protector, phase failure protector.
