Definitions

  • Spreader device for a vehicle, in particular a rail vehicle
  • the invention relates to a spreader according to the preamble of claim 1.
  • the aim of the invention is to provide a reliable leak-free system, which is equipped with a cellular wheel sand dosing and shut-off device, is compact and robust and can be installed in rail vehicles.
  • the spreader must provide a high and constant torque across all required speed ranges and is directly controlled across all speed ranges and, for structural reasons, does not include a primary gearbox.
  • These vehicles are usually equipped with a sanding system, which has a stepless or at least two-stage sand quantity control.
  • the sanding system and the amounts of sand are controlled in response to the respective vehicle speed by a vehicle-side control signal (for example, 0-10V and 4-2OmA) and corresponding pressure regulators.
  • the sand quantities become stepless or in at least two stages by defined speed ranges connected via a controllable pressure regulator.
  • WO 2001/068431 A1 describes a spreader with a storage container, a dosing device and a preferably compressed air-actuated conveying or discharging device for discharging the material to be spread, wherein a rotary valve is provided as dosing device for dosing of spreading material, which at least one rotatable about a rotation axis, to having this radially projecting conveying or closing surface.
  • the rotatable in the rotary valve cell serves on the one hand as a closure member for interrupting the sand flow between the reservoir and the injector and on the other hand as a conveyor to promote the sand to be discharged in the executed as an injector air-operated conveying or discharging.
  • the introduced via the rotary feeder into the injector sand is conveyed by means of compressed air via a sand hose to the scattering tube, from which it emerges as anti-slip material for a wheel.
  • DE 101 05 525 A1 discloses a spreader with a storage container and a metering device.
  • This metering device can, for example, be designed as a conveying or closing surface rotatable about an axis of rotation, e.g. as a rotary valve.
  • the metering follows in the direction of flow of the material to be spread an injector from which the material to be spread is conveyed via a sand hose to the scattering tube, from which it emerges as anti-slip material for a wheel.
  • DE 21 11 843 Al explains a sanding device to improve the adhesion conditions between the wheel and rail or roadway, the sand is conveyed by a mechanical launcher in the downpipes and passed through specially trained scattering nozzles safely to the point of contact between the wheel and rail or wheel and road becomes.
  • This mechanical launcher operates in the manner of a sand dosing and shut-off device.
  • the drive takes place by means of a pneumatic turbine wheel or by a micro-electric motor.
  • the compressed air for driving the turbine wheel also serves to blow out the sand through the downpipe and the scattering nozzle.
  • DE 195 47 746 Al a spreader with a reservoir, a metering device and a discharge device are removed, wherein after the metering device designed as an injector compressed air-actuated discharge device is provided for discharging the material to be spread.
  • the Vorschaltdüse also has the task of a defined back pressure according to the necessary pressure for the required defined safe operation of the spreader
  • the Vorschaltdüse depending on the actual system pressure has a diameter of 1 - 2 mm, preferably 1.5 mm.

  • the sand dosing and shut-off is denoted by 2 and surrounded by dash-dotted lines and has a throttle check valve 6 and a pressure regulator. 7
  • the vehicle with the compressed air controlled supply of the cellular wheel is designated in the drawing with 8. From there, the compressed air is passed through the compressed air hose 9 in the sand dosing and shut-off device 10, which, as already mentioned, the throttle check valve 6 and the pressure regulator 7 includes.
  • the compressed air hose 9 is also connected via a check valve 11 and the Vorschaltdüse 12 of the invention to the injector 3.
  • Hiebei also a radial piston motor 14 may be used, the motor-speed control has a throttle valve, which is located directly on the engine-compressed air connection and has a throttle valve upstream pressure regulator.

Abstract

L'invention concerne un appareil d'épandage pour un véhicule, en particulier un véhicule sur rails, pour le dosage d'une quantité de sable provenant d'un réservoir de sable (1) conjointement avec un dispositif de fermeture. Deux ensembles fonctionnels autonomes sont prévus, le premier étant un dispositif à roue cellulaire, de dosage de sable et de fermeture (2) et le deuxième étant un système de transport de sable commandé de manière pneumatique, et fonctionnant selon le principe de l'injecteur, une buse montée en amont (12) étant prévue dans la conduite d'air comprimé menant à l'injecteur (3).
