Abstract

A cleaning machine (1) for cleaning building surfaces such as facades comprises a self-propelled platform to which an extendable lifting arm (16) is attached. The lifting arm (16) preferably consists of a number of mutually displaceable arm members (19) with continuously decreasing width. The lifting arm (16) is pivotally connected to the platform (3) at the widest element (21), and a cleaning head (17) is pivotally mounted on the narrowest arm element (22). When the end of the lifting arm (16) is brought close to a surface, the cleaning head (17) is pushed out of its equilibrium position and then gently touches the surface under the effect of the weight force. With appropriate cleaning heads (17, 101), the machine can be used for both flat and corrugated surfaces.

Description

  • The present invention relates to a treatment machine according to the preamble of claim 1. Furthermore, the invention relates to a cleaning head for such a machine according to the preamble of claim 20.
  • The exterior surfaces of buildings must be periodically cleaned to preserve the aesthetic impression and extend the life of the building. In addition to walls and facades, these exterior surfaces also include the roof surfaces, in particular sloping roof surfaces, which are covered with bricks or slabs. For cleaning it counts not only the actual removal of dirt and vegetation (moss) and the preservation, z. B. by spraying with dirt and / or water repellent agents and the like.
  • Conventionally, it is necessary to attach scaffolding to the house. This results in additional costs. In addition, the weather may cause delays if cleaning is only possible under certain weather conditions. Such delays lead to additional costs as the scaffolding has to stay longer than planned.
  • Rooftops are a particular problem. Often, they are only accessible to a limited extent and scaffolding is difficult to install. Often it is therefore necessary to clean the roofs with cleaning equipment with long stems in laborious manual work and edit.
  • In the NL-A-1016679 is a machine for such work described. This machine consists of a platform on a vertically extendable mast is attached. At the extendable end of a cleaning device is mounted with a brush roller. For a gentle but effective cleaning of a house wall, it is necessary to adjust the pressure of the cleaning device and to ensure a concern even on irregular surfaces. The script gives no indication.
  • For practical reasons, another problem is facades with uneven surfaces, such as corrugated iron or trapezoidal sheet metal. The particular brush used must have such a bristle contour that it extends into the recesses to the bottom of the grooves and cleans when at the same time other parts engage the protruding areas. In addition, the division of such facades is different. It is therefore a large number of different brushes needed or even a special brush per facade to achieve a cleaning effect down to the depth of the profiles.
  • An object of the present invention is to provide a treatment machine for the surfaces of sloping or vertical building surfaces, which ensures a controlled concern of the cleaning element.
  • Another object of the present invention is to provide a cleaning head which can be used for a plurality of uneven facades.
  • Such a machine is specified in claim 1. The further claims indicate preferred embodiments and applications of the machine. A cleaning head which achieves the second object is specified in claim 20.
  • Accordingly, the machine according to the invention is characterized in that the cleaning part is movably suspended from an extendable support so that the center of gravity of this cleaning part is below the movable connection with the support. If the end of the carrier moved up to a house wall, it is initially a touch of the cleaning device, for. B. a brush roller, with the surface. If the roller then moves over an elevation or the like, it is simply pushed backwards, the pressure initially changing only slightly under the effect of gravity. The distance of the support end from the house wall is controlled approximately at the location of the movable attachment of the cleaning part by a distance sensor.
  • Conversely, it is advantageous to choose the distance from the wall of the house a little less than necessary, so that the cleaning device is already pushed out of the equilibrium position by the wall of the house, which results in a certain, desired pressure due to its weight. From this position, she is able to follow even depressions and similar irregularities that the mentioned distance sensor does not or only later detected.
  • The setting of the distance of the carrier end is preferably carried out in the inventive machine in that the carrier is tilted from a vertical position forward on the wall of the house. For this purpose, the carrier is mounted pivotably on a platform. The pivoting movement is controlled by a traction means, for. B. by a rope which can be shortened or extended via a hydraulic actuator in conjunction with a pulley-type roller assembly.
  • In a preferred embodiment, the carrier consists of a number of carrier elements, which have a continuously decreasing width from a first, lowermost element to an upper, last element. This makes it possible to attach guide rollers on the wider element in a simple way on the sides, which engage from the outside in each case a guideway in the sides of the narrow, next support element. In particular, in this embodiment, the guideways are guided over the entire length of the support element. The guide rollers can be attached to ribs that project forward from the side members of the arm members. This attachment is on the one hand and on the other hand stiff, so that a wide extension of the arm elements is possible.
  • For the cleaning of uneven facades, a cleaning head with at least two brushes is proposed. The one brush is intended essentially for cleaning the protruding facade parts, the second has a succession of sections of a larger radius, which are able to engage in the depressions or furrows of the uneven facade. To adapt to different furrow heights, one of the two brush rollers is arranged to be movable relative to the other in such a way that the engagement depth of the second brush roller is adjustable to the conditions of the façade surface. With such an arrangement, it is thus possible to clean facades of different depths. Instead of brush rollers while other, mechanically processing the surface facilities are conceivable as standing brushes, doctor blade.
  • The invention will be further explained in a preferred embodiment with reference to figures.

  • 1 shows an overall view of a façade cleaning machine 1 according to the invention. The cleaning device 5 is arranged on a self-propelled platform 3 with crawler track 4 on a turntable. The self-propelled platform can z. As the chassis of a small excavator, as it is used in landscaping. He is so well known and will not be described in detail. An advantage of such a self-propelled platform are on the one hand, the easy availability and off-road capability, the bringing of the machine 1 on facades in difficult terrain allowed. The slewing ring makes it possible to bring the landing gear to a building in any orientation relative to the wall or facade. In particular, it is also possible to drive along the facade during cleaning, so that horizontal tracks of the facade can be processed by the cleaning machine 1.
  • The mentioned turntable is not shown in the figures, as well known from the mentioned small excavators ago. It is also worth noting that the mounted on the turntable platform 9 is tilted to compensate for a deviating from the horizontal ground surface can.
  • Often it is necessary, especially for high facades, to widen the footprint of the chassis of the facade cleaning machine 1. For this purpose, the self-propelled platform 3 is equipped with extendable supports 10. The supports 10 are on the one hand horizontally extendable by pushing out the struts 11. On the other hand, the stamp 12 are movable in the vertical direction, for. B. by hydraulics or a crank mechanism.
  • The struts 11 of the front pillars 13 are additionally aligned forward beyond the front edge of the self-propelled platform 3 in order to achieve additional stability when moving the center of gravity forward.
  • The cleaning device 5 consists essentially of the drive and control part 15 and the extendable lifting arm 16 with a cleaning head 17 attached thereto in a pendulum manner. The lifting arm 16 consists of a number of arm elements 19 whose width decreases from the widest element 21 to the narrowest element 22. The elements 19 are a rectangular frame construction made of hollow profiled tubes. On the sides of each Elements 19 is in each case between two spaced apart tubular profiles 24, a web 25 is formed, which together represent a spar. In each track 25 run rollers 27, 31 which are each attached to the next broader element 19.
  • Due to the decreasing width of the arm members 19, it is possible to attach the rollers 27 to tabs 29 which are secured by the arm member 19 at the top of the tubular profiles 24 (in Fig. 5: right). Each arm element 19 has on each of the two narrow sides two such tabs 29 with roller 27, 31 (see Fig. 6). At the lower end of the tracks 25 are closed by a small plate 33. Near the upper end of the track 25, a pin 34 is inserted through the tube profiles 24 to also limit the track 25 at the top. Plate 33 and pin 34 serve as stops for the rollers 31 and 27 during extension and retraction of the arm members 19. The rollers 27, 31 have a distance of about one quarter of the length of an arm member 19 from each other, wherein a pair of rollers 31 on lower end of the arm members 19 is located. Together with the pin 34 as an upper stop for the upper roller 27 is thus determined that the arm elements can each be extended to about ¾. Surprisingly, the lever proved thanks to the good leadership and the decreasing width of the arm elements even with full extension of all arm elements 19 by far enough stiff that the machine could work easily, especially the correct distance of the upper end of the lift arm was observed without disturbing vibrations.
  • The tube profiles 24 together with the connecting webs 35 form the sides of the arm elements 19. They are connected by horizontally extending tube profiles 37 (top) and 38 (bottom), for which oblique struts 40 (see FIG. around the arm members 19 against shearing stabilize. The embodiment shown in the figures, except for Fig. 1, however, does without such struts, if the said tube profiles are chosen to be resilient and stiff accordingly.
  • At the lower end of the widest arm element 22, the lifting arm is rotatably supported in blocks 40 which are located on the platform 9. The lifting arm can thereby be tilted forward from the substantially vertical or even slightly inclined position (see Fig. 1) (see Fig. 3). By simultaneous displacement of the arm members 19 against each other, the lifting arm can be folded far forward, as indicated by dashed lines (Hebearmausschnitt 42) in Fig. 3. The said tilting movement is controlled by two chain mechanisms mounted on the widest arm element 21 to the right and left, of which the one shown in FIG. 3 is the foremost one in the direction of view. The second Kippbewegungsantrieb is accordingly on the other side and is identical.
  • The chain 44 in this drive is fastened to the widest arm element 21 on the one hand and to the crossbar 46 of a hydraulic cylinder 47 on the other hand. Starting from the attachment point on the crossbar 46, the chain 44 passes over a first roller 49, a second roller 50 attached to the crossbar 46 and via a third roller 51 to the attachment point widest on the element 21. By this inverse pulley arrangement, the movement indicated by arrow 52 of the hydraulic cylinder 47 converted into a three times as large movement of the attached to the arm member 21 chain end. Therefore, a hydraulic cylinder with a correspondingly shorter stroke can be used.
  • To stabilize against the high tensile forces occurring the strut 53 serves.
  • At the narrowest, foremost arm member 22, a pendulum 54 is movably mounted at the upper end. The vertically hanging down part 55 of the pendulum arm is a lattice construction similar to the arm members 19. At the upper end extends in Figs. 3 and 4 to the left a boom, at the end of the movable attachment to the narrowest arm member 22 is located. In the other direction protrudes a Distanzmessarm 60, at which a wheel 62 is located as investment sensor. The wheel 62 is displaceable against spring force in the horizontal direction, d. H. in Fig. 4 to the left, stored and coupled to a sensor or switch 64. Thus, if the pendulum 54 is moved to a wall, the wheel 62 is pushed to the rear or left and thereby the switch 64 is actuated. In a further developed embodiment, a sensor is used for the switch 64, which emits a signal depending on the position of the wheel 62, whereby a better tracking of the pendulum arm is possible relative to a facade.
  • Seen from the side, the pendulum arm 54 thus has an overall T-shaped configuration. At the main part 56 of the pendulum arm 54, the cleaning head 17 is attached. The cleaning head 17 has for this purpose at the rear a support 68 which can be moved on the pendulum arm main part 56 according to arrow 70 (see the lower, dashed line position 69 of the cleaning head 17). Conceivable here are many different ways of attachment, such. As well as the execution of the sides of the main part 56 similar to the sides of the arm members 19, wherein the carrier 68 has rollers which run in the path of these side parts.
  • At the lower end of the pendulum arm 54 guide rollers 71 are present. They pass the lower end over projections etc. of the facade.
  • The cleaning head 17 is equipped with a brush 72 and associated drive 74. Above the brush 72 is a high-pressure spray bar 76, here equipped with seven rotating nozzles 77. These nozzles 77 emit a sharp jet, which, however, moves by rotation along a cone shroud. Brush type as well as nozzle number and type can be adapted to the corresponding requirements of the surface to be cleaned. In particular, it is also possible to dispense with the nozzles or the brush, if a spraying or a mechanical action is not required.
  • The cleaning liquid, which is discharged through the high-pressure nozzles 76, is provided by a high-pressure pump in the drive and control part 15 and led via hose lines (not shown) to the cleaning head 17.
  • The brush 72 and the high-pressure spray bar 76 are shielded by a hood 78 to the rear and partially laterally.
  • The extension and retraction of the lifting arm as well as the up and down movement of the cleaning head 17 on the pendulum 54 is generated via a cable 80, one end 82 is attached to the cleaning head 17 and zig-zag via corresponding rollers 88, 90 in the Arm members 19 extends. Its other end 84 is attached to a winch 86, which is located in the drive and control part 15. For safety reasons, the cable 80 consists of two individual steel cables, so that in case of tearing a rope anyway an orderly retraction of the lifting arm 16 without destroying the machine or damage to the facade, which is currently being processed, is possible.
  • The cable 80 extends approximately centrally through the arm members 19. In the direction of the winch 86 to the cleaning head 17, the ropes of the cable 80 first pass through the first, down-mounted cable rollers 88 which are arranged between the side parts of the arm members 19. The cable continues to the second pulley rollers 90 at the upper end of the arm members 19. The second pulley rollers are on an axis 91, which are held by rearwardly projecting, attached to the side parts of the arm members ribs 92. In the widest, wind-next arm element 21, no first cable pulleys 88 are present, so that the cable runs directly to the upper, second pulley rollers 90 (see Fig. 3). Of the upper pulley rollers 90 of the narrowest arm member 22 of the cable via rollers 94 of the pendulum arm 54, which are located at the upper end of the main part 56 to the support 68 of the cleaning head.
  • This cable guide causes when tightening the cleaning head 17 is initially pulled on the pendulum 54 upwards, then the arm members 19, starting with the narrowest arm member 22 are progressively extended to the widest arm member 21 without further action to be taken.
  • In general, the facade cleaning machine 1 is moved up to a facade and performed by extending the lifting arm 16 and the cleaning head 17 method on the pendulum 54 of the cleaning head in vertical paths across the facade. For the lateral displacement of the machine, this can either drive parallel to the facade with its caterpillar drive or be displaced laterally by driving back and forth.
  • However, certain facades require cleaning by moving the cleaning device in the horizontal direction. For such cases, the cleaning part of the cleaning head 17 with brush 72, high pressure spray bar 76 and drive 74 is rotatably mounted on the carrier 68. Fig. 4 shows the cleaning head in such a rotated position in which the brush 72 is vertical. For the movement of the cleaning head 17, the cleaning device 5 is rotated at an angle of about 90 ° to the self-propelled platform and the cleaning machine moves during cleaning along the facade.
  • The obvious advantage of the façade cleaning machine according to the invention is that no scaffolding has to be erected even with high facades. Also, a much greater cleaning performance is achieved: while with manual cleaning of 1 m 2 / min. is assumed, with the inventive machine cleaning services of z. B. 20 m 2 / min. be achieved.
  • In a practical embodiment, the lifting arm comprised nine arm elements each 2.3 m long. The maximum height of the lifting arm was thus about 15 m. Another advantage of choosing this measure is that the machine can be transported without extra precautions because of oversize. This also contributes significantly, that the lift arm can be folded completely forward.
  • As already mentioned, the brush can be adapted to a wide variety of applications. Hard brushes are z. B. suitable for plaster, while soft brushes are used for blinds and glass. To prepare a wall for plastering is dispensed with a brush at all and a cleaning made only with high-pressure water jets.
  • Figures 7 to 9 show a second cleaning head 101 suitable for processing uneven surfaces.
  • As unevenness are in the cleaning direction running grooves or furrows as in corrugated or trapezoidal sheet metal facades.
  • From top to bottom, the cleaning head 101 has the following facilities:
    • • Water scraper 103 with two lips 105, which are held by resilient steel strips 107. The spring steel strips 107 serve to keep the sealing lips 105 in contact with the machined surface during operation.
    • Upper Spray Bar 109, which is used to spray a water repellent onto the cleaned surface.
    • • Upper brush roller 111 for cleaning in the depth of the furrows of the surface. It has a sequence of sections of large 113 and smaller 115 bristle length. The pitch, ie the distance between two centers of the sections 113, for example, is adapted to the spacing of the grooves of the facade. The upper brush roller 111 is displaceable transversely to the working surface, ie to the surface to be machined, in order to be able to set the engagement depth of the long-bristle sections 113. The bearings 119 are attached to a respective carrier 121 which can be attached to a tab 123 in various positions 125.
    • • (high pressure) spray bar 76.
    • It is shown here in a shorter length than the upper depth brush roller 111, but may also have other lengths, in particular the same or a larger than the upper depth brush roller 111.
  • The arrangement of the two brush rollers 111, 127 and the spray bar 76 is covered by the hood 78 to the rear. The mentioned components are attached to a frame 131. The frame 131 takes the necessary precautions to, as indicated above, clean the cleaning head 101 on the lift arm 16, i. on the pendulum arm 56, and to move along the pendulum arm 56.
  • In addition, two tabs 133 with eyes 135 are still present, which project upwards. Ropes 137 (see Fig. 9) of a crane or similar can be attached to the eyes 135. be attached to the cleaning head 101 on the ropes 137 hanging on a facade 139 to move up and down. The pressure is thereby effected by a train of ropes 137 to the facade 139 out.
  • The drive of the brush rollers 111, 127 is effected by a motor 74 which drives a triple belt pulley 143 via a belt 141. A second belt 145 passes from the belt roller 143 to the second, non-adjustable brush roller 127. A third belt 147 passes around the belt roller 143, the belt roller 149 of the upper brush roller 111, and a tension roller 151.
  • The tension roller 151 serves to compensate for the change in the distance between the belt rollers 143 and 149 when the height of the brush roller 111 above the basic cleaning level, (Plane tangential to lower brush 127 and substantially parallel to the direction of travel of the cleaning head), ie the engagement depth of the brush roller 111, is adjusted. The tension roller 151 may be spring-loaded or slidably mounted in conjunction with a locking device, such as a clamping device such as a screw in a slot of a moving together with the pinch roller member. Such clamping devices are known per se, which is why a detailed illustration can be omitted.
  • It should be noted that the belts 141, 145, 147 may be simple belts, timing belts or V-belts. A replacement by other propellants such as chains is conceivable.
  • Fig. 8 shows the cleaning head 101 on a pendulum arm 54 of a facade cleaning machine 1, Fig. 9 as a stand-alone cleaning unit, which is moved on ropes 137 on a facade 139 upwards and downwards, as already mentioned above. Incidentally, in principle, the cleaning head 17 described above is also suitable for hanging use according to FIG. 9.
  • Surprisingly, it also shows that especially the second cleaning head 101, presumably because of the presence of two brushes, but also with careful adjustment of the first cleaning head 17 can be used suspended for cleaning a facade according to FIG. 9, without the head begins, on the facade surface to jump.
  • Numerous modifications will be apparent to those skilled in the art from the foregoing description without departing from the scope of the invention, which is defined solely by the claims. Conceivable z. B .:
    • Nozzles having a different beam characteristic, such as a wider beam or nozzles that produce a mist;
