Definitions

  • the invention relates to a rail vehicle with a device for cleaning wall or floor surfaces, in particular within tunnels or separating surfaces, for example of track superstructures or tunnel walls, the device having a plurality of both sides of a suction air nozzles arranged for compressed air. Furthermore, the invention relates to a method for operating the device.
  • Tunnels, walls and ceilings are subject to permanent heavy pollution due to the vehicles passing through the tunnel, so cleaning is required at regular intervals.
  • devices of the type mentioned which are used for surface cleaning in local railways as an essential part of entertainment. Due to the increasing pollution of the railway by waste, but also by brake sand, dust and metallic abrasion of the rails, measures must increasingly be taken to solve the problem of surface cleaning and thus not only to improve the appearance of the railway facilities, but also the To maintain elasticity of the ballast track by reducing pollution.
  • WO 2010/075828 A1 a device for cleaning tunnel walls and tunnel ceilings and for suction and cleaning of ballast bedding is known in which by an inclination of the air nozzles a cleaning area immanent vortex is produced, which ensures the functionally necessary overpressure curtain.
  • the loosened or dissolved dirt particles are sucked into the absorbent body specifically by the inclination of the air nozzles.
  • the DE 92 03 164 U1 further relates to an attachable to a rail or Mehrweghus device for cleaning the track body with a lowerable suction box and at least one compressed air nozzle in the suction box, wherein the suction box and the Compressed air nozzle with a suction unit or a compressor are in communication, which are arranged on the vehicle.

  • a laterally extending beyond the two rails suction box has distributed over its entire width several compressed air nozzles made of elastic material.
  • the US 2,932,845 A refers to a street cleaning vehicle, each with a front in the direction of travel of the vehicle and arranged behind a suction nozzle. In this case, for example, 20% more air emerges from a nozzle in the direction of travel behind the suction opening than from a nozzle in the direction of travel in front of the suction opening.
  • the JP 2003-313840 A relates to a street cleaning vehicle in which compressed air is deflected to the ground from a plurality of nozzles arranged in a plurality of rows in front of and behind a suction opening.
  • the invention has for its object to provide a way to increase the cleaning performance, which can be realized with a relatively low cost. In particular, an increase in efficiency should be achieved according to the invention.
  • a rail vehicle is provided with a device which has at least two air nozzles arranged in each case as a row of nozzles adjacent the suction opening, and between which the nozzle rows can be acted upon with compressed air, such that the pressure prevails in the direction of travel of the vehicle the suction opening arranged nozzle row is dimensioned smaller than the pressure of the other nozzle row, wherein the air nozzles have an adjustable angle of inclination and / or distance relative to the suction opening or the wall or bottom surface.
  • the invention is based on the recognition that at least one of the suction openings is enclosed by a first row of nozzles arranged in front of the suction opening in the direction of travel of the rail vehicle and a second row of nozzles arranged behind it, so that the suction area is defined and bounded by the rows of nozzles.
  • the respective pressurization is set so that the pressure of the front row of nozzles in the direction of travel is less than that of the rear row of nozzles, soiling of all kinds, such as objects, dust or other deposits are received between the rows of nozzles.
  • the effective suction power is achieved in that the rows of nozzles have an adjustable angle of inclination and / or distance to the surface so as to achieve by a change of the flow angle with respect to the main extension of the surface optimally adapted to the respective type of contamination removal rate.
  • the change can also be made during the supply of air pressure, so as to pressurize adhering dirt particles with alternating pressure loads.
  • the device adjacent to the suction opening at least one spaced apart from the cleaning wall or bottom surface positionable air guide have, by means of which the compressed air supplied by means of the rows of nozzles is first deflected between the latter and the air guide element substantially parallel to the surface after striking the wall or floor surface.
  • the invention is based on the recognition that the efficiency and thus the efficiency of the device during operation can be substantially increased if at least a substantial portion of the air flow generated is not turbulent, but substantially laminar parallel to the wall or bottom surface.
  • Such a laminar air flow is inventively achieved in a simple manner by a local separation of the air nozzles and the suction opening in conjunction with a flow zone in which the supplied air flow is guided by means of the air guide element substantially parallel to the surface of the object to be cleaned.
  • a defined course of flow which is clearly divided into a zone, in particular a deflection zone of the supplied compressed air, parallel to the surface to be cleaned and a further zone in the inlet region of the suction opening. It is thus achieved a problem-free separation of the supplied and the extracted air flows and avoided an undesirable mixing zone.
  • the cleaning performance can be increased or the required aggregate power can be reduced.
  • the air nozzles have an orientation that is inclined relative to the bottom surface, ie in particular with the bottom surface forms an acute angle, and if the air nozzles are inclined so that at least the rear nozzle row directed to a bottom surface area below the suction opening is. By this inclination, the air flow is directed directed to the ground surface, that Contaminations transported in the direction of travel and can be carried to the extraction.
  • another embodiment of the invention which is also particularly practical, is also achieved if the air guiding elements can be positioned parallel to the wall or bottom surface to be cleaned, so that a constant flow velocity of the compressed air is ensured over the entire area covered by the respective guiding element.
  • the air nozzles or the air guide elements for adjusting the orientation in particular jointly pivotally adjustable, in particular movably or pivotally mounted so as to make a quick adaptation to different nature of the surface to be cleaned. For example, in the area of an extended track bed, as occurs in the area of stops, a corresponding adjusting movement can be initiated so as to achieve a complete suction.
  • a modification is also particularly relevant to practice, in which the device can be positioned relative to the surface at different distances.
  • the advantageous effect results in the flow velocity between the suction and the surface, which can be adjusted at the same time in the desired manner by adjusting the distance. Based on the determined degree of contamination so the flow can be adjusted by simply lowering or raising the device or the air guide elements to the required cleaning performance.
  • a suction opening can be realized with a circular inlet opening which is enclosed by a single concentric air guide element.
  • the suction opening is enclosed on at least two opposite sides of the nozzle rows, so that a substantially strip-shaped suction area is defined.
  • the surface of the air guiding element can be adjustable, that is to say be enlarged or reduced in size, so as to be able to achieve optimum adaptation to the respective operating conditions without a change in the system technology.
  • the air nozzles could be arranged on or connected to an outer edge region of the air guide elements.
  • a plurality of air nozzles are arranged on a common receptacle, wherein the air nozzles are preferably arranged side by side, for example along a straight line and at a constant distance from each other.
  • different air nozzles of the same nozzle row are subjected to a different pressure for individual control.
  • the receptacle can be positioned in an orientation parallel to the main extension of the surface, so that the distance between the air nozzles and the surface is constant, at least for a substantial part, and therefore the pressure distribution is homogeneous due to the compressed air impinging on the surface ,
  • the distance of the air nozzles from the suction opening in the plane parallel to the surface can be varied so as to be able to adapt the contact surface accordingly.
  • a design in which the air nozzles of the suction opening have a distance transversely to the suction direction of at least 50 mm, in particular at least 150 mm is particularly practical.
  • the air nozzles can connect to the respective air guide element on the circumferential side directly, that is to say substantially without a gap, or can have a suitable spacing therefrom.
  • the air guide element of the suction opening at a distance transverse to the suction between 50 and 300 mm, preferably between 80 and 120 mm, wherein the suction direction is parallel to the surface normal of the surface to be cleaned.
  • the device is basically suitable for almost any chassis.
  • the device forms, together with a dirt collecting container and a drive unit, an autonomous mobile unit which can be used without problem in the area of municipal subways.
  • the device is not limited to the cleaning of floor surfaces. Rather, the device is by a movable in several horizontal or vertical positions arrangement alike for wall or ceiling surfaces. In this way, therefore, the entire tunnel cross-section can be treated by means of several devices in a single cleaning pass accordingly. If only partial areas are to be cleaned, then the devices associated with the other areas can, if necessary, be assigned to the areas to be cleaned in order to further improve the cleaning performance there.
  • the device for cleaning wall or floor surfaces, in particular within tunnels or other lateral or upper boundary surfaces, for example of track superstructures and tunnel walls
