Definitions

  • the invention relates to a cleaning device for cleaning the appearance of escalators and moving walks according to the preamble of claim 1.
  • Escalators and escalators with a grooved surface are used both in covered rooms and outdoors. Especially those that are completely or partially arranged outdoors
  • a disadvantage of the described device is the relatively complex construction for the rotating brushes, which also has the disadvantage that the device does not clean, at least on one side, to the edge of the escalator, since the rotating brush requires storage and a drive, which is at least appropriate connects to the brush on one side.
  • a cleaning device for escalators which has a brush protruding into the grooves of the escalator, by means of which the dirt is loosened and also a suction device, which largely sucks off the loosened dirt. Due to the relatively high contact pressure of the brush for dry cleaning, which is necessary for a satisfactory cleaning result, these brushes are exposed to severe wear. A Dry cleaning also sometimes leads to poor cleaning results, since a large part of the dirt cannot be removed by dry brushing.
  • the present invention is therefore based on the object of developing a cleaning device of the type mentioned above in such a way that a good cleaning effect is achieved with the simplest construction.
  • the injection device comprises a large number of injection nozzles which are directed into the spaces between the webs of the escalator and / or reach there and the
  • Suction device has a plurality of ribs, which reduces the suction volume in the spaces between the escalators.
  • the cleaning device consists of a base plate to which the suction device can be attached, the
  • Cleaning brushes and the injection device can be attached in modular order in any order.
  • the device according to the invention has the special feature that the shape of the device fits into the grooves of the escalator. Furthermore, water, steam and / or air are supplied individually for each groove. The injected water or steam jet has a strong mechanical dirt release effect due to the injection into the grooves. In order to achieve a satisfactory cleaning effect of the cleaning brushes, a certain contact pressure of the cleaning device on the escalator is necessary. This contact pressure is caused, among other things, by the suction device Negative pressure formed. It is also advantageous that the escalator can be cleaned during operation, the cleaning device being arranged at the top or the bottom of the escalator. The length of the device is preferably less than 30 cm.
  • the following modules are arranged one after the other as seen in the direction of travel of the escalator:
  • a brush module with scratching brushes the injection module, the suction module, another brush module and a brush module with fine cleaning brushes.
  • an injection device is arranged in front of and behind the suction device.
  • the dirt is sprayed on both sides in the direction of the suction device and can then be immediately removed from the suction device.
  • Brush modules are preferably provided which have straight scratch brushes which clean the upper edge and the bottom of the grooves.
  • a further brush module which has star-shaped fine cleaning brushes that clean the spaces between the webs.
  • the suction module comprises ribs which engage in the spaces between the webs, but only partially fill these spaces, so that a strong suction effect is caused by the suction device in the remaining grooves.
  • the suction device forms a cavity above the webs of the escalator, which merges into a suction funnel or suction nozzle.
  • the suction module is connected to a commercially available vacuum cleaner for wet dirt via this suction nozzle. 4
  • the cleaning device described can advantageously be used for any width of staircase, it being possible to clean the entire tread surface up to the edge of the staircase both on the left and on the right.
  • the cleaning device does not include any moving parts, is light and simple, and the modular parts mean that the wearing parts, e.g. the brushes can be easily replaced. An adaptation to different stair geometries is also possible.
  • the cleaning device is very compact, preferably not longer than 30 cm, and can therefore be used without restriction. The cleaning device cleans all surfaces of the appearance of an escalator or an escalator without the need for chemical cleaning agents.
  • the invention is based on a
  • Figure 1 a bottom view of the cleaning device
  • Figure 2 shows a side section through the cleaning device along the central longitudinal axis
  • FIG. 3A a longitudinal section through the cleaning device and the tread of the escalator in the area of the injection nozzle;
  • Figure 3B a cross section through the cleaning device and the tread of the escalator in the area
  • Figure 4 is a schematic representation of the water, steam and / or compressed air supply

  • FIG. 8 a view of the suction module from below
  • Figure 9 shows a cross section through the suction module
  • Figure 10 shows a cross section of the cleaning device
  • the cleaning device is described using the example of an escalator with steps. However, it goes without saying that this cleaning device is also suitable for running ramps or moving walks with grooves.
  • the cleaning device comprises a base plate 1, on which all modules of the device are attached.
  • the cleaning device is in the entry area of the escalator 20 whose tread surface is attached, the area of the cleaning device upstream of the escalator running direction 23 being referred to as the front and the area of the cleaning device downstream of the escalator running direction 23 being referred to as the rear.
  • fastening eyelets 2 are provided on the base plate, by means of which the cleaning device is anchored with a chain or a rope, so that the escalator 20 runs under the cleaning device during operation.
  • a guide finger 3 is arranged in the front area of the base plate 1 and engages in a groove in the tread surface of the escalator 20. Behind the guide finger 3 there is a first brush module with scratching brushes standing vertically downwards for cleaning the upper side of the webs 21
  • Grooved injection nozzles 7 Water or steam and / or air is fed to the injection module under pressure via a water / steam / air inlet.
  • the medium used loosens the dirt in the grooves of the escalator.
  • Behind the injection module is a suction module 9, which has a multiplicity of ribs 11, which each engage in the grooves of the escalator 20.
  • the space 22 in the grooves of the escalator is, however, only partially filled by the guide webs 11, so that the dirt loosened by the medium is sucked off by the strong suction effect via the suction funnel 10.
  • a cavity 12 is arranged above the guide webs 11, so that the negative pressure formed by the suction device 9 is evenly distributed over the individual grooves of the escalator 20.
  • the base plate 1 has an opening 15 and a free surface 16, so that a second if necessary 7
  • Injection module can be used in this area to achieve an even better cleaning effect.
  • Downstream of the brush module 13 is another brush module 17 with a plurality of fine cleaning brushes each filling one groove of the escalator 20, through which the side walls of the webs 21 and the base of the intermediate spaces 22 are cleaned.
  • the base plate 1 is preferably made of metal and can have a weight 19 to increase the cleaning effect in order to press the brushes into the grooves of the escalator 20.
  • Injection nozzles 24 preferably into the spaces 22 of the escalator 20, a large number of small outlet nozzles being provided for the water-steam jets 25.
  • the injection nozzles 24, viewed in the running direction 23 of the escalator, are arranged at an angle so that the dirt particles released by the jet of the cleaning medium are pressed in the direction of the suction device 9.
  • Figure 4 shows the water, steam and / or compressed air supply.
  • a water-steam source 26 is provided, which is connected to the nozzles 24 via a line 27 and an adjustable throttle 28.
  • a compressed air source 29 can be provided, which also opens into the injection nozzles 24 via a line 30 and a controllable throttle 31.
  • Figures 5A and 5B show the structure of the first brush module with scratching brushes 5, which are relatively short, so that they clean the top of the webs 21 of the escalator 20.
  • a further brush module 13 with longer scratching brushes 14 is provided in order to clean the bottom of the grooves in the escalator 20.
  • a further brush module 17 with fine cleaning brushes 18 finely cleans each groove.
  • the fine cleaning brushes are roughly U-shaped and run in the longitudinal direction of each groove. These brushes consist of a core on which the bristles are arranged in a star shape, so that the side walls of the webs 21 and the bottom of the grooves of the escalator 20 are cleaned.
  • these fine cleaning brushes are staggered in pairs in order to
  • FIG. 8 shows a view from below of the suction device 9 and the ribs 11. These ribs 11 are arranged such that they engage in the spaces 22 of the escalator 20. A cavity 12 is formed over the ribs 11, which ensures a uniform distribution of the negative pressure to the individual intermediate spaces 22.
  • the suction device is shown again in cross section.
  • FIG. 10 finally shows the suction device 9 in engagement with the escalator 20.
  • the escalator 20 can be seen with webs 21 and intermediate spaces 22 in which the ribs 11 engage. However, these spaces are only partially filled by the ribs 11, so that a sufficient space remains between the webs 21 and ribs 11 so that the dirt can escape through the suction effect of the suction device 9 into the cavity 12 and can then be suctioned off via the suction funnel 10.
