Description
Technical field
The present invention relates to rolling stock, especially a kind of device preventing railway switch ice and snow from freezing.
Background technology
In equipment of railway transportation, track switch is very important ingredient, and the closely connected situation of track switch has vital impact for the safe operation of railway transportation.Northern China is comparatively cold for winter, and generally have snowfall, accumulated snow not easily melts, for communications and transportation brings very big inconvenience.When having snowfall winter, the accumulated snow without process in time can freeze on the movable position of track switch and road bed board.When track switch needs conversion, the accumulated snow at point tongue place also can be squeezed into ice-like by the action of goat, causes track switch not carry out normal conversion, thus affects normally carrying out of receiving and dispatching trains operation and shunting service.
At present, main both at home and abroad exist following several railroad switch snow removal mode: electric heating snow melting, shading type snow defence, melting snow on turnout junction agent snow removing, wind-force snow removing.But above method can solve track switch accumulated snow problem to a certain extent, but all there is defect: electric heating snow melting system needs to continue rail heating, and power consumption is large, and it is high to introduce price, maintenance work difficulty; Shading type snow protection device can only stretching out without during train operation, train by time must pack up, reliability is low; Melting snow on turnout junction agent is used to cause saline Land, harm environment; The accumulated snow fallen in track switch blows away by Wind snow-removing device, but cannot process to have condensed becomes the snow of ice cube.According to the retrieval, current existing snow-removing device for railroad switch, the Chinese patent application being 200410082931.7 as: publication number discloses a kind of railroad switch snow remover, this device utilizes blower fan to remove the snow pipe ventilated to air draft, exhaust vent on recycling snow removing pipeline is by outside snow blowout track switch, but this patent is blown from lower to upper by wind, relatively power consumption, and easily block the mouth of pipe, moreover this patent be by pipe arrangement in the middle of track, installing a little difficulty, and the normal operation of vehicle can affected.And ozzle is parallel to rail and above rail in this application, parallel current exports, relative energy-saving, and can not block ozzle, and the application is mounted in outside track switch, can not affect railway normal operation.Publication number be 201410325539.4 Chinese patent application disclose a kind of railway switch wind-force snow removal system, this system utilizes high-pressure air source outwards to dispel accumulated snow to the blower be placed on inside rail for gases at high pressure, this system can reach the object of snow removing, but can not prevent snow from falling into track switch, and not easily dispel when accumulated snow crosses dark or crystallization.Therefore existing railway switch snow protection device has very large shortcoming in snow defence effect and operability.
Summary of the invention
The object of the present invention is to provide a kind of railway switch snow protection device, prevent snowflake from dropping to switch zones, fundamentally solve the problem of track switch accumulated snow, to ensure the normal operation of receiving and dispatching trains operation and shunting service, and this device is had structure is simple, safe and reliable, energy-conserving and environment-protective, advantage that cost is low.
The present invention realizes the technical scheme that its goal of the invention adopts:
The course of work is as follows:
A kind of railway switch superficial air fluid layer snow protection device, comprises the air compressor 2 that controls by station control terminal 1 and is connected with air compressor and Compressed Gas is delivered to the air duct of protected railway switch, air jet pipe and ozzle.The air jet pipe 4 be erected on support 5 is arranged at railway both sides Parallel Symmetric, and parallel ozzle 6 outlet on air jet pipe 4 is parallel to protected track switch rail 8 surface; Air duct 3 one end connects air compressor 2, and the other end connects air jet pipe 4; Air compressor 2 is placed in outer cover case 7.
Adopt railway switch superficial air fluid layer snow protection device of the present invention, utilize the compressed air that air compressor provides, by air duct, gas is delivered to jet pipe, jet pipe is by stent support, the airflow layer spraying certain pressure intensity is continued in snowy day, above track switch, form Air-inflated umbrella, stop snowflake to contact with track switch.Specific implementation process is: railway operator on duty finds to snow, open station control terminal system control switch 1, air compressor 2 opened by gauge tap 1, air compressor 2 is started working, continue to provide Compressed Gas to air duct 3, the parallel ozzle 6 of Compressed Gas on air jet pipe 4 outwards sprays, and forms the air layer being parallel to railway roadbed, air layer stops that snowflake falls, and is formed " Air-inflated umbrella ".When stopping snowing, by staff's shutdown system gauge tap 1.
Compared with prior art, the invention has the beneficial effects as follows
One, the present invention passes through air compressor 2 by supercharging air speedup, be sent to jet pipe (6) by gas pipeline 3, the gas of ozzle ejection is formed " Air-inflated umbrella " above railway switch, prevents snowflake from dropping on track switch, ensure the normal conversion of track switch, used manpower and material resources sparingly;
Two, the present invention prevents snowflake from falling into track switch, fundamentally solves track switch accumulated snow problem, separately can be combined with existing snow removing mode, forms mixing snow removing, raises the efficiency, more improve safety;
Three, installation site of the present invention is lower, and jet pipe center and rail of railway outer horizontal range are 75mm, and vertical distance is 50mm, guarantees that train can not touch with its generation through out-of-date, improves travel safety;
Four, control circuit of the present invention is simple, only needs logic circuit to control the duty of air compressor, thus ensure that the reliability and security of this working state of system;
Five, structure of the present invention is simple, without precision element, can firmly be arranged on railroad tie, convenient disassembly, is convenient to maintenance and changes part;
Six, only have air compressor to consume electric energy when the present invention works, energy ezpenditure is little; And take horizontal gas flow, power consumption is less, further energy conservation;
Seven, the present invention adopts ozzle to form air layer, guarantees that parallel current exports, forms steady air flow plane, can better cover switch zones.
Eight, the material that the present invention adopts all has good rigidity, indeformable; There is good corrosion resistance simultaneously, comparatively rugged environment can be adapted to.
Nine, the present invention adopt jet pipe and ozzle cross section be circle, avoid snowflake to pile up, serve good anti-freezing anti-blocking effect;
