Definitions
- State of the art features many distribution devices for distribution of very complex Composite Heavy Fluid Compound (CHFC). These are due to nature of distribution and due to physical size usually remote in relation to point of application and dosage of medium. The remoteness of the device means several seconds needed for material to arrive through the distribution network to the point of application on the wheel which is not acceptable with acceptable times up to 250 ms. In addition the current guides of the applicator used by state of the art distributors are flat, and this can lead to damage of the wheel surface.
- CHFC Composite Heavy Fluid Compound
- line distributor preferably for anti- noise device for rail brakes wherein the line distributor is positioned directly next to rails to provide for accurate dosage in real time and in required-desired quantity.
- the dosage tubes are reduced to the length enabling correct operation of an applicator.
- the device is preferably used for application of anti-noise material onto wheels of rail vehicles.
- flat guides of the applicator are replaced with guides with rounded, preferably essentially elliptical, more preferably essentially circular cross section so the edges of damaged wheels do not transfer shocks onto the device.
- the distributors in general are devices used for distribution and dosage of medium onto the wheel of the rail vehicle which is approaching part of the rails with additional friction between wheel rim and rail or some other device such as rail switch, rail brake, lead rail or some other device.
- the medium for purposes of this application in this case is means for spreading around the wheel and it does not necessarily mean means for lowering of a friction coefficient - in fact it may even mean means for increase of said friction coefficient.
- Said medium according to this invention is preferably very complex Composite Heavy Fluid Compound (CHFC).
- the line distributor is used for application of medium for rail brakes which means that the medium adds to increase of friction coefficient while adding to decrease of noise between rail brake and wheel rim during breaking.
- the line distributor arranged along the rail in part where the medium should be applied onto the wheel ' s flanks is comprised of arbitrary number of built mini pumps, and is driven by means of electro motor, pneumatic motor, wheels of rail vehicles or by any other means, said line distributor providing the wheels with medium, preferably very complex Composite Heavy Fluid Compound (CHFC).
- CHFC Composite Heavy Fluid Compound
- Fig. 1 shows main drive train 1, auxiliary drive train 2, guide tube 3, brush 4, dosage nozzle 5, applicator guide 6, spring bracket 7, dosage tubes 8, inlet tube 9, mini pump 10, return tube 1 1.
- Fig. 2 shows main drive train 1, auxiliary drive train 2, guide tube 3, brush 4, dosage nozzles 5, applicator guide 6, spring bracket 7, dosage tubes 8, inlet tube 9, mini pump 10, return tube 11, wheel 12, rail 13.
- the device is comprised of main drive train 1 (in this application drive train describes a device or plurality thereof usually comprised of pumps, supplies tubes, control and regulation and other similar devices providing for standalone operation of fluid supply at predetermined flow rate and/or pump head) which supplies medium, preferably very complex Composite Heavy Fluid Compound (CHFC) to auxiliary drive train 2 from container.
- the main drive train 1 is comprised preferably of pump with sufficient pump head and flow rate so the auxiliary drive train 2 is supplied with sufficient amount of medium to be applied onto the rails and is switched on if needed (when supplying of said rails by medium is foreseen by anticipated passing of the wheel 12).
- the auxiliary drive train 2 is connected to main drive train 1 by means of inlet tube 9 for inflow of lubricant, and return tube 1 1 for return of excess medium.
- the auxiliary drive train 2 comprises mini pump 10 or plurality thereof.
- the auxiliary drive train 2 is activated by proximity of wheel 12 in such a way that mini pump 10 or plurality thereof is activated, and medium is applied to passing wheel ' s flank 12 through dosage nozzle 5 or plurality thereof.
- Said mini pump 10 may be therefore on need-to basis when the wheel 12 enters the distributor area. During this time the mini pump 10 pumps said medium from amount supplied by the main drive train 1.
- Dosage nozzle 5 or plurality thereof are connected to mini pump 10 or plurality thereof by means of dosage tubes 8.
- the dosage nozzles 5 are connected by means of dosage tubes 8 in such a way that each mini pump 10 supplies one dosage nozzle 5.
- each mini pump 10 supplies plurality of dosage nozzles 5, or alternatively that plurality of mini pumps 10 supplies single dosage nozzle 5, or combination of both.
- the dosage nozzle 5 is enlarged at the exit so wider application of said medium is enabled. They are also positioned on the top of applicator so they are least exposed to the dirt and other impurities and enable the most efficient applications of said medium onto said wheel 12.
- the applicator guide 6 serves for transversal movement of guide tube 3, the spring bracket 7 compensates the shocks arising from the wheel 12 hitting the guide tube 3.
- the applicator guide 6 therefore provides for transversal adjustment of applicator to the wheels 12 of the rail vehicles while the spring bracket 7 provides for damping during entry into said applicator.
- Preferred embodiment features the guide tube 3 added to the device, preferably in pair, said guide tube 3 providing guiding of wheel 12 on rail 13 in such a way that wheels 12 which may be damaged do not transfer shocks to the device according to this invention as such shocks could damage said device.
- guide tube 3 has ellipse cross section preferably round (circular) cross section such guide tube 3 is elastically adjusting to possible uneven running of said wheel 12 which in turn causes said wheel 12 to run smoother and with less noise between said guide tubes 3.
- the guide tube 3 touches due to its form the wheel in a line providing for barrier between the gravel bed and the wheel 12 forming an obstacle between the wheel 12 and the gravel bed preventing run-off of said medium from said wheel onto said gravel bed. Further, the guide tube 3 provides for further spreading of said medium onto said wheel 12. Last but not least due to small contact surface (thin contact line) the friction between the wheel and the guide tube 3 is decreased.
- the dosage nozzle 5 can feature elongated cross section. In preferred embodiment it is essentially elliptic in cross section, however it can also be essentially rectangular in such a way that long axis of ellipse or long side of said rectangle is approximately parallel to movement of said rail vehicle. Such form of the dosage nozzle 5 results in thicker or larger trail, this having advantageous effect on reduction of friction.
