    TECHNICAL FIELD This device describes a procedure and a city device. More specifically, a method and a city device for cleaning an escalator, a conveyor belt or the like, when this is in operation.
    BACKGROUND Escalators, for example, in a building are often loaded by thousands of people who use them daily. In addition, the escalator is often one of the first places a visitor arrives at in the building, which means that dirt, dust and sludge from the outside are often deposited and get stuck on the escalator steps. Furthermore, the escalator is often exposed to unusually responsive soiled dirt in the form of chewing gum, wedged smast, broken glass and the like. The escalator often becomes a breeding ground for bacteria and microorganisms as a result of the high throughput of users, which is why decay in an escalator can cause blackish damage.
    In this document, the term escalator, unless otherwise stated, is also used to denote other forms of escalators, moving pavements or conveyor belts which comprise a plurality of interconnected plates intended to transport a human or other load, whether or not they include a step.
    A dirty escalator is not only unpleasant for a visitor and a potential contagion; dirt can also lead to operational disruption. Furthermore, the safety of the escalator can be compromised as a dirty and / or bare surface increases the risk of slippery damage. Furthermore, dust accumulation in connection with escalators poses a fire hazard.
    When cleaning an escalator or a conveyor belt with previously known cleaning equipment, a number of problems arise. SarIan's previously known cleaning equipment is often based on some form of rotating brush with limited capacity. This makes repairing an escalator time-consuming and therefore costly.
    Another problem is to clean the joint or transition between two steps that form the lateral surface of the step. This surface lateral surface is sometimes referred to as set steps. With existing cleaning equipment, this is often not possible, which is why city staff are instructed to clean these surfaces completely or partially by hand, which is time consuming. If this surface is inadequately cleaned, a traveler in the escalator may risk having their clothes, such as the lower part of trousers or a skirt / dress and / or possibly washed soiled. 2 In addition, prior art cleaning equipment often requires the escalator to be turned off during cleaning. This is of course a great antiquity for travelers who may have a disability or travel with heavy luggage. In order to reduce such a disturbance, perhaps the parking and the associated closure of the escalator must be done at times when few travelers are in circulation, such as late at night. However, this is impractical for the caretaker who then has a very inconvenient working time. Sometimes solvents are used to dissolve ingrained dirt, oil and the like. Often the janitor has to inject this solvent by hand, which is time consuming. In addition, excess solvent and dissolved dirt must be collected and wiped. If this is done by hand, the support will be very time consuming.
    Another problem with previous bachelor cleaning equipment for escalators is that this equipment is often very large and heavy. This makes it cumbersome, or perhaps impossible for the janitor to handle this equipment, perhaps especially since this former Unda cleaning equipment also presupposes that the Ors parking lot is then closed off. The equipment must then be stored up the escalator one step at a time during the city process. Such heavy and awkward equipment can amen to a workplace hazard, as a serious accident can be the result if the caretaker loses control of the cleaning equipment, for example Mgt up an escalator.
    Furthermore, the side plate at an escalator often has a protruding edge with a protective plate. This protruding edge means that previously known cleaning equipment, which is more or less block-shaped, will not clean the outermost part of the edge of the escalator step on each side. This must therefore be cleaned by hand, which is time consuming and laborious.
    Furthermore, there are previously known cleaning equipment that uses water or other liquid to clean the escalator and dissolve dirt. The problem with spraying water into the escalator is that it must dry before the escalator can be used again due to the risk of slipping. This prolongs the time the escalator must stand still further. Furthermore, uncontrolled spraying with water can cause flooding and / or moisture damage, for example in a space covered under the escalator. Water can also damage electronic components in the escalator.
    It can be stated that much remains to be done to improve the decontamination of escalators and similar devices. SUMMARY It is therefore an object of this invention to be able to solve at least some of the above problems and to improve the process of cleaning an escalator, conveyor belt or the like with a cleaning device and to achieve an improvement of a cleaning device.
    According to a first aspect of the invention, this grinding is achieved by a cleaning device for cleaning an escalator, a conveyor belt or the like when it is in motion. The cleaning device comprises at least one rotating brush for brushing dirt from a staple plate in the escalator. Furthermore, the cleaning device comprises at least one high-pressure nozzle, connectable to a pressure tank containing a liquid, pressurized with a pressure exceeding the ambient atmospheric pressure, the high-pressure nozzle being arranged to spray the escalator with said liquid. In addition, the cleaning device comprises at least one vacuum cleaner nozzle, connectable to a pump, for evacuating liquid through the vacuum cleaner nozzle.
    According to a second aspect of the invention, this grinding is achieved by a method in a cleaning device for cleaning an escalator, a conveyor belt or the like when it is in motion. The method involves spraying the escalator with liquid through a high pressure nozzle in the cleaning device. Furthermore, the method comprises brushing a staple plate in the escalator with a rotating brush in the cleaning device. The method also includes vacuuming liquid and dirt through a vacuum cleaner nozzle in the cleaning device.
    By including a rotating brush, high-pressure nozzle and vacuum cleaner nozzle and coordinating the effect between these, for example by feeding how much liquid is sprayed out of the high-pressure nozzle and how much liquid is sucked through the vacuum cleaner nozzle, it can be calculated and determined how much liquid is left in connection. the escalator and which need to be evacuated separately. This reduces the amount of liquid that must be evacuated, thereby reducing the risk of water damage. In addition, the caretaker becomes aware of how much liquid is left adjacent to the escalator and that needs to be evacuated.
    By further coordinating control of spraying with the high-pressure nozzle so that only the joint between two staple plates is sprayed with high-pressure, the amount of liquid used for cleaning in the escalator can be further reduced, which further reduces the risk of 4 water damage and shortens the drying time of the escalator. This results in an improvement of the cleaning device.
    Other advantages and additional features will become apparent from the following detailed description.

    Figure 1A shows a cleaning device 100, arranged for cleaning an escalator, conveyor belt or the like. The cleaning device 100 comprises a protective cap 1 which encloses various means for cleaning such as one or more brushes, one or more high pressure nozzles and / or one or more vacuum cleaner nozzles according to different embodiments, which will be described in more detail in connection with the description of Figure 1B. Figure 1A also shows a display 120, hdr arranged at the handle, and a control unit 130. This control unit 130 can be placed at any place in connection with the cleaning device 100.
    Figure 1B schematically shows the cleaning device 100, seen from the side and in section. The cleaning device 100 comprises one, or more, high pressure nozzle 150, connectable to a pressure tank containing a liquid, pressurized with a pressure exceeding the ambient atmospheric pressure. The high-pressure nozzle 150 is arranged to spray the escalator with rollers, which may consist of, for example, water, solvents, cleaning agents, water vapor, or a combination of these in different embodiments. By spraying the substrate on the escalator with liquid, dirt and the like stuck in the substrate can be dissolved, rinsed off and then removed. In some embodiments, the high pressure nozzle 150 may also be provided to guide the vapor, such as water vapor, to the stacking plates in the escalator.
    In some embodiments, the high pressure nozzle 150 may be mounted with a hinge 157 in a fixed device 159 and an actuator 1 which allows an operator to move in the other direction. the high-pressure nozzle 150 from a position outside the protective cap 110. Thus, the operator, or the local guard, can control the high-pressure nozzle 150 between spraying the escalator, or rinsing off a rotating brush.
    The control of the high pressure nozzle 150 can be done by the caretaker through a control handle which is located on the outside. the protective cap 110. In some embodiments, the control of the high pressure nozzle 150 may be made from the handle of the cleaning device.
    In this way, by enabling an uncomplicated and efficient method of cleaning the rotating brush, or brushes, the probability increases that these are often cleaned, for example at regular intervals. Furthermore, the brushes can be cleaned without this taking time from the city work with the escalator. In this way, by cleaning Ors with clean brushes, a more efficient cleaning of the escalator can be done.
    In the illustrated embodiment, the cleaning device 100 comprises a first rotating brush 1-1 and a second rotating brush 1-2. In this example, these rotating brushes 1 rotate towards each other, the rotating movement sweeping up dirt, dust, liquid, etc. on a respective conveyor belt 180-1, 180-2. The first conveyor belt 180-1 is driven by two. drive wheels 190-1, 190-2 and the second conveyor belt 180-2 are driven by two drive wheels 6 190-3, 190-4. In this case, these conveyor belts 180 will rotate so that dirt brushed on them will be transported to a collection container 170. The conveyor belt 180 may be formed of a rubber mat or the like, which may for instance comprise transverse strips to better catch dirt and dust.
    The rotating brushes 140 may be provided with bristles which, by the friction generated by the rotational movement upon contact with the substrate, generate static electricity which attracts dust particles. Furthermore, the cleaning device 100 also includes one or more vacuum cleaner nozzles 160. The vacuum cleaner nozzle 160 is connectable to a pump, for evacuating dirt, dust, liquid, etc. through the vacuum cleaner nozzle 160. The dirt collected in the collection container 170 can thus be sucked up and evacuated.
    Furthermore, certain embodiments of the cleaning device 100 also include a first feeder 155, arranged to feed the water basket passing out through the high pressure nozzle 150. The cleaning device 100 may also comprise a second feeder 16 arranged to feed the amount of liquid sucked up through the vacuum cleaner nozzle 160. much liquid left in the escalator by subtracting the amount of liquid sucked up through the vacuum cleaner nozzle 160 from the water basket sprayed out through the high pressure nozzle 150. Thus the janitor knows how much liquid is left in connection with the escalator, which needs to be sucked up or dried up afterwards. In some embodiments, the cleaning device 100 may include an alarm that warns when the amount of liquid sprayed exceeds a certain spruce value. These calculations of the amount of liquid sprayed and / or water shortage in the escalator can be made in the control unit 130.
    Furthermore, the cleaning device 100 may comprise a laser-based feeder 1 arranged to detect where the joint between two stacking plates in the escalator is located. The laser-based feeder 135 may be connected to a control unit 130, arranged to calculate when the high-pressure nozzle 150 is to spray the escalator to clean said joint, based on said detection made by the laser-based feeder 135. Such laser-based feeder 135 may be directed downwards, towards said stack plates. in the escalator and be arranged to feed the gap to the stack plate located below the feeder 135. When the distance to the base exceeds the achieved distance to the stack plate, or exceeds this by a certain spruce value, this is interpreted as a joint being located there. The control unit 130 may be arranged to calculate when the high pressure nozzle 150 is to spray the escalator and when the spraying is to be stopped, and also arranged to generate a control signal for activating or deactivating the spraying with the high pressure nozzle 150 in certain embodiments.
    According to some embodiments, the length of the escalator can also be fed with the laser-based feeder 135, or another similar laser-based feeder. According to certain embodiments, this length can be measured by a laser-based feeder 135, arranged to measure the length of the escalator. In other embodiments, the janitor may measure the length of the escalator, or simply unload the length of the escalator from a data sheet associated with the escalator and enter this information so that it is accessible to the controller 130.
    The control unit 130 can thus be arranged according to certain embodiments to, based on the feeding with the laser-based feeder 135, determine where a joint between two stacking platforms in the escalator is located and activate the high-pressure nozzle 150 so that this joint is sprayed with the liquid, after which the high-pressure nozzle 150 is deactivated.
    The laser-based feeder 135, or another similar laser-based feeder 135, may in some embodiments send a light signal, such as a laser beam, toward the upper end of the escalator. Furthermore, the feeder 135 can detect a reflection from the emitted laser beam and thereby calculate the distance from the cleaning device 100 and the laser-based feeder 135 to the far end of the escalator. In some embodiments, the feed can be made by placing the high pressure nozzle 150 at a level with a joint between two staples in the escalator. In some embodiments, the control unit 130 may then, with the aid of food data from the laser-based feeder 135, calculate when the usual joint between two stacking plates is flush with the high-pressure nozzle 150 according to certain embodiments. Furthermore, in some embodiments, the control unit 130 may calculate when the habit of joining occurs by dividing the estimated length of the escalator by an estimated length of the escalator in the escalator. In some embodiments, alternatively, the caretaker can feed and enter the length of the staples in the escalator.
    This also makes it possible for the control unit 130 to calculate how long the staging of the escalator takes, and / or to reduce the time or number of remaining stacking plates in the escalator. This information can further be displayed on the display 120. Furthermore, the display 120 can indicate, for example, when the escalator has rotated a whole vary with the cleaning device 100 activated. By calculating where the joint between two stacking plates is, it is possible to limit the high-pressure spraying with liquid to only the joints according to certain embodiments. In this way, the amount of liquid like any other can be reduced, which reduces the risk of flooding in the underlying premises and also reduces finishing work in the form of drying up the said liquid. I-1dr- through you reduce both working time and drying time. Furthermore, the cost of solvents or detergents, if anyands as an additive to the water, is reduced, as well as the environmental impact of solvents / detergents.
    The cleaning device 100 may further comprise a detector 137 according to certain embodiments, arranged to detect a marking 139 which can indicate that all the joints and staples in the escalator have been cleaned. The cleaning device 100 may also comprise a control unit 130, arranged to interrupt spraying with the high-pressure nozzle 150, when the detector 137 has detected said marking 139.
    The screen 120 may in various embodiments be arranged to display data comprising at least some of, for example, roller flow through the high pressure nozzle 150, the amount of remaining liquid in connection with the escalator stack plates, the amount of sprayed roller, the amount of liquid remaining in the container, number of steps / escalators / step plates to clean in the escalator, calculated water access to clean the escalator and / or calculated time to clean the escalator, to name just a few examples.
    In this way, the caretaker can be given latte-damaging information as the city process progresses, how much water has flowed out of the escalator, how long it is left and similar information.
    Figure 2 is a schematic illustration of the cleaning device 100 in an escalator 200. The escalator 200 comprises a number of staples 2-1, 2-2, 2-3, 2-4, 2-5, 2-6, 210-7, 210- 8, 210-9, which are separated by a number of joints 220-1, 220-2, 220-3, 220-4, 25, 220-6, 220-7, 220-8, 220-9.
    According to one embodiment, the janitor places the cleaning device 100 in the horizontal part of the escalator near a portion of the escalator. The escalator 200 is in operation during the cleaning according to certain embodiments. The janitor then activates the cleaning device 100 and allows the escalator to rotate a vary. In some embodiments, the cleaning device 100 is then moved, as necessary, to allow cleaning of the entire width of the stacking plates. The cleaning device 100 comprises in certain embodiments a cleaning means 250, such as a brush and / or a high-pressure nozzle 150, mounted on one side of the cleaning device so that cleaning is made possible by the outer edge of the escalator belt on this side. This makes it possible to clean the entire width of the staples, even if the side of the escalator has an edge that protrudes above the escalators 210 of the escalator.
    A standard width of an escalator 210 is 120 cm. An appropriate width of the cleaning device 100 and / or the protective cap 110 may be 60 cm, in order to be able to clean the escalator 200 in two varies, or 120 cm in order to be able to clean the escalator 200 in one vary. In some cases, the cleaning device 100 and / or the protective cap 110 may be 40 cm, which allows cleaning of the escalator 200 in three variations. A narrower cleaning device 100 and / or protective cap 110 provides a smoother and easier-to-handle cleaning device 100, while a wider cleaning device 100 and / or protective cap 110 allows for faster cleaning of the escalator 200.
    As the escalator 200 is cleaned during operation, the protective cap 110 fulfills an important function by preventing or at least evaporating odors from liquid, dust and dirt which may otherwise stink on travelers traveling with the escalator 200.
    Figure 4 illustrates an example of an embodiment of the invention. The flow chart in Figure 3 ashes a method 300 in a cleaning device 100 for cleaning an escalator 200, a conveyor belt or the like when it is in motion.
    The purpose of the method 300 is to better control the cleaning device 100 to clean the escalator 200.
    In connection with the cleaning of the escalator being drilled, the caretaker can, according to certain embodiments, attach a mark 139 to a staple plate 210 in the escalator 200. Thus the caretaker can easily determine when the escalator 200 has rotated a vary and thus the entire escalator has been cleaned according to method 300.
    Data related to the cleaning of the escalator 200 can according to certain embodiments be displayed on a monitor 120 in connection with the cleaning device 100. Such data may include, for example, some of: liquid flood through the high pressure nozzle 150, amount of remaining liquid in connection with the escalator 200, number of steps / stair plates 210 in escalator 200, number of cleaned steps / step plates 210 in escalator 200, number of remaining steps / steps 210 to clean in escalator 200, calculated water access to clean escalator 200, calculated time to clean escalator 200, or the like.
    In order to properly clean the escalator 200, the method 300 includes a number of steps 301-311. However, it should be noted that some of the steps described have only been included in certain alternative embodiments of the invention, such as, for example, steps 301303, 305 and / or 308-311. Furthermore, the described steps 301-311 can be performed in a slightly different chronological order than what the number order suggests and that some of them can be performed in parallel with each other. Method 300 includes the following steps: Step 301 This step may be performed in some, but not all, embodiments of method 300.
    A joint 220 between two staple plates 210 in the escalator 200 can be detected with a laser-based feeder 135. Such a laser-based feeder 135 can be directed downwards, towards said staple plates 210 in the escalator 200 and be arranged to feed the distance to the staple plate 210 located below the feeder 135. Since the distance to the substrate exceeds the measured distance to the stack plate 210, this is interpreted as a joint 220 being located there.
    According to some embodiments, the length of the escalator can also be increased. According to some embodiments, this length may be fed by a laser-based feeder 135, arranged to measure the length of the escalator 200. In other embodiments, the janitor may measure the length of the escalator, or simply read the length of the escalator from a data sheet associated with the escalator 200 and enter this information that it is accessible to the control unit 130.
    Step 302 This method step may be performed in some, but not all, embodiments of the method 300, where a joint 220 between two staple plates 210 in the escalator 200 has been detected 301.
    A calculation of when the high pressure nozzle 150 is to spray the escalator 200 with the high pressure nozzle 150 to clean said joint 220 can be made, and / or a calculation of when the spraying is to be stopped. This calculation can be done by matching the spraying of liquid with the high pressure nozzle 150, so that only the joint 220 between two stacking plates 210 is sprayed. The calculation may be based on the previously made detection 301 of said joint 220. By detecting 301 said joint 220 and calculating when a joint 220 is directly below the high pressure nozzle 150 and then activating spraying of the high pressure nozzle 150 in a high pressure pulse, the lateral can be cleaned. the surface, the set step, in the escalator 200, with a limited amount of liquid.
    The calculation of when the high pressure nozzle 150 is to spray the escalator 200 and when the spraying is to be stopped may include determining where the joint 220 between two staples 210 in the escalator 200 is located and generating control signals to activate the high pressure nozzle 150 so that this joint 220 is sprayed. The high pressure nozzle 150 is deactivated, according to certain embodiments.
    Step 303 This process step may be performed in some, but not all, embodiments of the process 300, particularly in embodiments where process step 302 is performed.
    Spraying with the high pressure nozzle 150 is controlled, based on the said calculation 302.
    In this way, the spraying of liquid with the high-pressure nozzle 150 can be adapted, so that only the joint 220 between two stacking plates 210 is sprayed. This reduces the amount of sprayed liquid in connection with the escalator 200, compared with a constant spraying with liquid. As a result, less liquid remains to be evacuated after the cleaning of the escalator 200, which speeds up the cleaning. This also reduces the risk of water damage, as well as the risk of slippery damage in the escalator 200.
    Step 304 The escalator 200 is sprayed with liquid through a high pressure nozzle 150 in the cleaning device 100.
    The spraying can be done with, for example, water, water vapor, cleaning agents, solvents or a mixture of these. Such a cleaning agent may comprise a surfactant or a surfactant which may modify the surface tension of a spruce surface. Said solvents may be, for example, ethanol, turpentine, ammonia, supercritical carbon dioxide, tetrachlorethylene, toluene, acetone, methyl acetate, ethyl acetate, hexane, citrus terpenes or the like, and may be a polar solvent, a protic solvent, an oprotic solvent, an aprotic solvent, a neoteric solvent and / or a non-polar solvent according to certain embodiments; or a mixture of a plurality of the above components. By spraying the escalator 200 with liquid, the friction of the rotating brushes 140 is reduced, which facilitates the cleaning of the escalator 200.
    Step 30 This process step may be performed in some, but not all, embodiments of the process 300.
    The water basket passing out through the high-pressure nozzle 150 can be fed with a first feeder 155. By "water basket" in certain embodiments can be meant water vapor.
    Step 306 A staple plate 210 in the escalator 200 is brushed with a rotating brush 140 in the cleaning device 100. The brush 140 may rotate parallel to the extension of the escalator, or perpendicular thereto in various embodiments.
    Step 307 Liquid and dirt are sucked up through a vacuum cleaner nozzle 160 in the cleaning device 100.
    Step 308 This process step may be performed in some, but not all, embodiments of the procedure 300.
    The amount of liquid sucked 304 through the vacuum cleaner nozzle 160 can be fed with a second feeder 165.
    Step 309 This process step may be performed in some, but not all, embodiments of the process 300 in which the amount of liquid aspirated 304 through the vacuum nozzle 160 has been fed.
    The amount of residual liquid adjacent to the escalator 200 can be calculated by subtracting the amount of liquid sucked up through the vacuum nozzle 160 from the amount of liquid passed through the high pressure nozzle 150.
    Step 3 13 This process step may be performed in some, but not all, embodiments of the procedure 300.
    A mark 139 is detected by a detector 137, which mark 139 indicates that all the joints 220 and stacking plates 210 in the escalator 200 have been cleaned.
    In connection with the cleaning of the escalator being drilled, the janitor can attach a mark 139 to a staple plate 210 in the escalator 200. Thus, the janitor can easily determine when the escalator 200 has rotated a vary and clamed the entire escalator has been cleaned according to procedure 300.
    The mark 139 may be constituted, for example, by an adhesive patch, with an adhesive coating on one side and a monochrome surface on its other side, in a certain color shade, the detector 137 being arranged to detect this particular color shade, according to certain embodiments.
    In other embodiments, the mark 139 may be, for example, a sticker with a one-dimensional or multidimensional bar code, a Quick Response (QR) code or the like, the detector 137 being separately arranged to detect this mark 139 and may be, for example, a bar code laser or the like.
    Step 311 This process step may be performed in some, but not all, embodiments of the process 300, especially in embodiments where process step 310 is performed.
    Spraying with the high pressure nozzle 150, can be interrupted 311 da. the detector 137 detected 310 said mark 139. This can be done by sending a control signal to stop the spraying. In some embodiments, the brush 140 and / or the vacuum cleaner nozzle 160 may also receive such a control signal to interrupt the cleaning of the escalator 200. In some embodiments, an indication that the cleaning is ready may be required to call the caretaker's attention to this, for example by an audible signal. and / or light signal or the like is generated. For example, a message may be written on the monitor 120.
    According to certain alternative embodiments, the cleaning can simply be interrupted when the caretaker notices that the entire escalator 200 has been cleaned. Figure 4 illustrates a schematic embodiment of a cleaning device 100 for cleaning an escalator 200, a conveyor belt or the like when it is in motion.
    The cleaning device 100 is configured to perform at least some of the previously described method steps 301-311, included in the description of the method 300 for cleaning an escalator 200.
    In order to be able to correctly clean the escalator 200, the cleaning device 100 comprises a number of components which are described in more detail in the following text. Some of the described sub-components occur in some, but not necessarily all, embodiments. There may also be additional electronics or mechanics in the cleaning device 100, which is not entirely necessary to understand the operation of the cleaning device 100 according to the invention and is therefore omitted here, for the sake of clarity.
    The cleaning device 100 includes at least one rotating brush 140 for brushing dirt from a staple plate 210 in the escalator 200.
    Furthermore, the cleaning device 100 comprises at least one high-pressure nozzle 150, connectable to a pressure tank containing a liquid, pressurized with a pressure exceeding the ambient atmospheric pressure, the high-pressure nozzle 150 being arranged to spray the escalator 200 with said liquid. In particular, according to certain embodiments, the high-pressure nozzle 150 is arranged to spray the gap 220 between two stacking plates 210 and thereby clean the set step in the escalator 200.
