Definitions
- the invention relates to a method for removing ice and / or snow from a bogie of a railway vehicle according to the preamble of claim 1 and to a device for removing ice and / or snow from a bogie of a railway vehicle. and / or snow from a bogie of a rail vehicle according to the preamble of claim 8.
- a generic method Cleaning jets of hot water under pressures up to 200 bar, which are also directed to the bogie caliper units, gearbox and speed sensors to free them of ice and / or snow.
- this can lead to high overhaul costs and even brake failures when water enters the interior of the caliper units, e.g. enters the sealed pneumatic brake cylinder of a caliper unit or a sealed gear and sealed speed sensors.
- the object of the invention is to further form a method described above or a device described above such that ice and / or snow can be effectively solved and transported away from the surfaces of a bogie of a rail vehicle, but the bogie or on the bogie arranged assemblies such as braking devices is not affected.
- the invention is based on a method for removing ice and / or snow from a bogie of a vehicle.
- At least one cleaning jet containing solid particles is directed onto the bogie in such a manner that ice and / or snow are released from surfaces of at least some assemblies of the bogie and transported away, wherein the bogie in the installed state on the rail vehicle, while the at least one, solid particles containing cleaning jet acts on its surfaces.
- a cleaning device for removing ice and / or snow from a bogie of a rail vehicle when installed on the rail vehicle is also provided, which is designed to at least one cleaning jet containing solid particles on the in the installed state located on the rail vehicle to direct bogie so that ice and / or snow layers at least detached from surfaces of at least some modules of the bogie and transported away.
- a bogie of a rail vehicle to a drive of the rail vehicle to be understood which usually has two wheelsets, which are mounted in a rotatable relative to the car body of the rail vehicle frame.
- the bogie should include all assemblies and parts here, which are arranged or held on the bogie such as braking devices, speed sensors and gearboxes.
- the solid particles preferably transported at the speed of sound with the at least one cleaning jet hit the ice and / or snow layer on the bogie and penetrate into the ice and / or snow layer.
- CO2 dry ice particles
- the carbon dioxide abruptly sublimes upon impact or penetration into the ice and / or snow layer and becomes gaseous.
- the at least one cleaning jet can be generated by means of at least one cleaning nozzle.
- the at least one cleaning jet can be formed by forming liquid carbon dioxide under overpressure by relaxing after leaving the at least one cleaning nozzle solid carbon dioxide particles, in particular dry ice.
- the at least one cleaning jet therefore contains by expansion from liquid, formed under pressure carbon dioxide solid carbon dioxide particles (dry ice).
- a mixture of a gas and a solid carbon dioxide (dry ice) granules can be used to form the at least one cleaning jet.
- the at least one cleaning jet may therefore contain a mixture of a gas and a granulate consisting of solid carbon dioxide (dry ice).
- the at least one cleaning jet is generated by means of at least one cleaning nozzle in such a way that it has a speed which is smaller, greater or equal with respect to the speed of sound.
- an assembly of the bogie, from which ice and / or snow is removed arranged on the bogie braking device of the rail vehicle, in which case the braking device, from the surfaces of ice and / or snow is to be removed, for example
- a) is formed by a disc brake device, which comprises a brake caliper unit from a brake pads carrying brake caliper and a frictionally cooperating with the brake pads brake disc, or
- a block brake device which comprises a bearing at least one brake pad and pivotable relative to a bracket block holder and a frictionally cooperating with the brake pads together surface of a wheel of the rail vehicle.
- FIG. 1 shows a side view of a bogie of a rail vehicle, which is freed by means of a preferred embodiment of a cleaning device of ice and / or snow;
- FIG. 2 is a perspective view of a brake caliper unit designed as a brake device comprising cooperating with a brake disc brake caliper, wherein the Brake caliper unit by means of the preferred embodiment of a
- Cleaning device is freed from ice and / or snow
- Blocking device formed braking device the brake caliper unit is freed by means of the preferred embodiment of a cleaning device of ice and / or snow.
- a bogie 30 of a rail vehicle which has a rotary pan 32 as an assembly, which is rotatably mounted relative to a carriage body, not shown, about a vertical axis.
- a cradle 34 is attached as a further assembly on which a spring 38 is mounted as an assembly via secondary springs 36, on which primary springs 40 axle bearings 42 of axles from here, for example, two sets of wheels 44 are resiliently mounted as assemblies of the bogie 30 ,
- a braking device 22 of a disc brake device of the rail vehicle is shown in FIG.
- the braking device 22 has a brake caliper unit 10 with a compact brake caliper 6 and a non-axially fixed brake disc, not shown here, with which it cooperates frictionally in a known manner.
- Brake pad holder 1 with brake pads 8 are pivotably mounted on brake caliper levers 4 by bolt connections 2 on the compact brake caliper 6.
- the brake device 22 of the rail vehicle can also be designed as a block brake device according to FIG. 3, where a brake pad holder 24 is shown with a brake pad 8, which is pivotably supported by brake lever 26 and a piston rod and a bolt connection 28 relative to a bracket 12. It is now assumed that in addition to other surfaces or components and assemblies of the bogie and the surfaces of the braking device 22 of Figure 2 or Figure 3 are partially or completely covered by a layer of ice and / or snow, which the function of the braking device 22nd impaired, as may occur, for example, in a winter operation of the rail vehicle.
- a cleaning device for removing ice and / or snow from surfaces of the bogie 30 and here exemplified by surfaces of the bogie arranged on the brake device 22 when installed on the rail vehicle or on the bogie 30 of the rail vehicle is provided, of which in FIG. 2 and Figure 3 only a cleaning nozzle 14 can be seen.
- Components of the cleaning device are also a compressor and a tank, wherein the compressor from the tank liquid, pressurized carbon dioxide (CO2) pumping into the cleaning nozzle 14.
- CO2 pressurized carbon dioxide
- the liquid carbon dioxide (CO2) leaves the cleaning nozzle 14 under high pressure in the form of a cleaning jet 16, wherein the relaxation after leaving the cleaning nozzle 14 solid carbon dioxide particles, in particular dry ice particles are formed.
- the cleaning nozzle 14 is arranged, for example, at the end of a hollow cleaning lance, which can be performed by an operator mobile.
- a hollow cleaning lance which can be performed by an operator mobile.
- the cleaning lance for example, extends a cleaning channel, in which the liquid carbon dioxide (CO2) from the tank in particular by means of a flexible hose through the compressor is pumped.
- the boundary conditions and in particular the pressure generated by the compressor and the formation of the cleaning nozzle 14 ensure that the cleaning jet 16 leaves the cleaning nozzle 14 preferably at the speed of sound or at supersonic speed.
- the cleaning lance is directed with the cleaning nozzle 14 by the operator at a certain distance on the surfaces of the braking device 22.
- solid carbon dioxide particles in particular dry ice particles within the cleaning jet 16 form.
- the cleaning jet 16 therefore contains by expansion from liquid, formed under pressure carbon dioxide solid carbon dioxide particles (dry ice particles).
- the solid dry ice particles transported with the cleaning jet 16, preferably at the speed of sound hit the ice and / or snow layer on the surfaces of the braking device 22 and penetrate into the ice and / or snow layer.
- the solid dry ice particles sublimate abruptly upon impact or penetration into the ice and / or snow layer and become gaseous, increasing their volume by approximately 700 to 1000 times.
- the gaseous sublimated carbon dioxide which has penetrated into the ice and / or snow layer breaks up this layer from the surfaces of the braking device 22.
- the cleaning jet 16 may also contain other solid particles. Furthermore, it can also be provided that the cleaning jet 16 contains a mixture of a gas and granules consisting of particles, in particular dry ice particles. LIST OF REFERENCE NUMBERS
