    The invention relates to a scaffold for processing of house facades with at least one working platform, which is slidably mounted on at least one post in the axial direction, wherein on the working platform a working device is slidably mounted.
    In the device, which is the subject of the present invention, it is a scaffolding, which serves to edit house facades or hall walls.
    This processing may include painting or plastering the house facade or even the washing of glass facades or the like.
    Scaffolding generally serves to carry out work on buildings or facilities, which, however, serve only as an auxiliary construction and are usually removed after the work.
    Among other things, a scaffold is made up of several similar floors and columns that can be combined differently from one site to another, repeatedly resulting in individual constructions. The higher the house facade to be worked, the more floors the scaffolding needs and the wider, the more columns are used. The construction of a scaffold can therefore be relatively time-consuming and can again only be carried out manually.
    The work that is done with the help of the scaffolding on the building, as a rule, can also be carried out only manually and can be automated only with considerable effort. Therefore, the labor demand is often relatively high.
    In CN 102 493 630 a mobile scaffold is disclosed which has two vertical rails and a horizontally displaceably mounted horizontal rail on which the work equipment is mounted and can automatically machine the house facade. The vertical rails are mounted on a mobile platform. The disadvantage of this design is that the rails are fixed only to the mobile platform, therefore, the free deflection by bending at the upper end of the vertical rails can be large. The device is not suitable for high and large house facades because it is not stable enough. In addition, the position often has to be changed with wider house facades, which increases the workload.
    Object of the present invention is to avoid this disadvantage and to provide a device of a scaffold, which allows little free deflection and is also suitable for high and large building facades and is more stable, and which makes it possible to edit even without frequent position changes a wide house facade ,
    According to the invention, it is provided that the framework has at least one support beam which is connected to the upright and which is held with fastening elements outside the working range of the work implement. By this support beam, the movement of the free end of the stirrup can be limited and the entire structure has a higher stability. In addition, the slidable bearings between the upright, the work platform and the implement allow automated operation. The device requires only a small amount of material. Thanks to the support beams, the device can be used for any height of house facades. The invention is particularly well suited for processing as flat as possible house facades without bay or balcony.
    It is particularly advantageous if the framework has at least two posts. This has the advantage that even with longer house facades sufficient stability is ensured.
    In a particularly preferred embodiment, the working platform for vertical movement has an actuator. This can be an electric motor with pinion and rack or with winch and ropes. This allows easy movement of the work platform in the vertical direction.
    It is particularly advantageous if the implement has an actuator for movement on the work platform. This actuator can be realized for example by an electric motor with pinion and a rack. This has the advantage that the movement along the work platform is made possible in a particularly simple manner
    It is alternatively possible that the implement is movable along the working platform by means of a linear drive. This can be an electromechanical linear drive. The advantage of this design is that a higher precision in the horizontal movement is achievable.
    In a particularly preferred embodiment, the working device is a spraying device. Their advantage lies in the fast, even and efficient way of working.
    For safety reasons it is preferred that the post is secured at an upper end with a securing element, and therefore the device is secured against falling over.
    It is favorable that the upright has a foot, which is preferably designed to be mobile. This has the advantage that the scaffolding is easier to set up and even when installing a new part of the house facade is faster to move. For long house facades, it is advantageous that the work platform consists of several modules which can be plugged together and thus the working platform can be adapted to the length of the house facade.
    It is particularly favorable that the implement has at least one, preferably inductive, sensor for detecting windows, doors and end positions and thus the crash of the implement or the unwanted editing of windows and doors can be prevented.
    It is particularly advantageous that the implement is connected via at least one hose with at least one reservoir and the reservoir is located in a support cage, which is mounted on the work platform. As a result, the area that can process the implement without filling can be extended many times without increasing the moving load along the work platform. On the one hand, this saves energy and, on the other hand, protects the device with regard to the mechanics, since the reservoir only has to be moved vertically.
    In a particularly preferred embodiment, the framework is divided into three levels, wherein the working platform is located in a first level, which faces the house facade, the post is in a second level and the support bar is located in a third level. This has the advantage that the framework is particularly simple.
    In the following the invention will be explained in more detail with reference to the embodiment shown in the figures. 1 shows a first embodiment of the scaffold according to the invention; FIG. 2 shows a mode of operation of the framework; FIG. FIG. 3 shows a working platform of the scaffold; FIG. 4 shows the modular structure of the work platform of the scaffold; • Figure 5 shows the connection between the working platform modules and the support beams; FIG. 6 shows a second embodiment of the framework; FIG. FIG. 7 shows a third embodiment of the framework; FIG. FIG. 8 is a side view of the framework; FIG. and FIG. 9 shows a detail of the framework.
    In Fig. 1, a framework 10 is shown. This has two vertical uprights 11. The uprights 11 are each in a foot 12. Each foot 12 has four wheels 13 in order to move the uprights 11 faster. After setting up the scaffold 10 at its destination, the feet 12 are either anchored to a building 1, or in the ground to ensure sufficient stability. Each upright 11 is secured to the building 1 at the upper end with a securing element 14.
    At the side facing away from the building 1 side of the uprights 11 two support beams 15 are mounted at different heights. These support beams 15 connect the two uprights 11. Each support bar 15 has a horizontal axis of use 15a in the position of use. The two beam axes 15a are arranged parallel to one another. The beam axes 15a are at right angles to the post axes 11a.
    At the four ends of the two support beams 15 are each a fastener 16. These fasteners 16 are mounted outside the working area 6 of the frame 10 on the side surfaces 2 of the building 1.
    The framework 10 has a working platform 30 in a first plane 17. This working platform 30 faces the house facade 3 of the building 1 and is arranged vertically displaceable between the uprights 11 and the house facade 3.
    The uprights 11 are located in a second plane 18. The support beams 15 are in a third plane 19, which faces away from the house facade 3.
    Due to the position of the fastening elements 16 and the securing elements 14, the working area 6 of the framework 10 is accessible without hindrance.
    The work platform 30 has two rails 31, which are provided for guiding a working device. In the illustrated embodiment, the implement is designed as a spray device 32.
    On the uprights 11, the working platform 30 has an upper end position 20 and a lower end position 21, so that the entire working area 6 of the house facade 3 can be achieved. It rests on two carriers 22. These carriers 22 are connected to the uprights 11 and the work platform 30. The work platform 30 has an actuating device. The actuating device is designed as a motor 33 in the illustrated embodiment. The motor 33 drives two pinions 34, which engage in two racks 23.
    The two racks 23 are attached to the uprights 11, the house facade 3, attached. With this actuator, the movement of the work platform 30 is accomplished in the vertical direction.
    FIG. 2 shows the simplified operation of the spray device 32 on a building 1. The spraying device 32 sprays the working area 17 of the house facade 3 of the building 1 automatically.
    The work platform 30 is first in its upper end position 20 and the spray device 32 moves to a first horizontal end position 35 on the
    Work platform 30 and then performs the spraying on the house facade 3 and moves from the first horizontal end position 35 to a second horizontal end position 36 on the work platform 30. If the spray device has arrived in the second horizontal end position 36, the working platform 30 moves down and the spray device now moves from the second horizontal end position 36 to the first 35 back. It is always the defined working area 17 sprayed.
    This process is repeated until the lower end position 21 of the work platform 30th
    In another embodiment, it is possible that the work platform 30 begins in its lower end position 21 and that the house facade 3 is processed from bottom to top. During the drive from top to bottom no spraying takes place by the spray device 32. Thus, it is possible to spray with the spray device 32, the entire surface of the house facade 3 of the building 1.
    It is also possible that the spray device 32 must be brought in a further embodiment of the second horizontal end position 36 without spraying into its first horizontal end position 35 to start again with the spraying can after the vertical position of the working platform 30 has been changed.
    In the embodiment shown, the spray device has a plurality of sensors. An inductive proximity sensor 37 is used to detect windows 4. The windows 4 can be protected by the inductive proximity sensor 37 and by means of a controller 38 before spraying. Likewise, the spray device 32 is equipped with a limit sensor 39. With this, the horizontal end positions 35, 36 can be recognized on the work platform 30 and the spray device 32 can automatically reverse its direction of travel on the work platform 30. In order to be able to recognize a window 4 with the inductive proximity sensor 37, magnetizable rods 49 are attached to the windows 4 in preparation. To recognize doors 5, the same procedure is necessary.
    In order to be able to recognize a window 4 with the inductive proximity sensor 37, magnetizable rods 5 are attached to the windows 4 in preparation. To recognize doors 5, the same procedure is necessary.
    The work platform 30 consists of several modules plugged together 40, as shown in Fig. 3 can be seen. These modules 40 are plugged together so that the length of the working platform 30 reaches the width of the house facade 3 of the building 1. The modules 40 are such that they can easily be assembled and disassembled by hand. At the lateral ends of the working platform 30 are each a side wall 41. These two side walls 41 regulate the horizontal end positions 35, 36, which define the driving cycle of the spray device 32.
    On the work platform 30 is a second rack 42, which moves in combination with a second pinion 43 and a second motor 44 on the spray device 32, this in the horizontal direction. To guide the spray device 32 are located on the work platform 30, the two guide rails 31, in the four rollers 45 which are mounted on the spray device 32, run.
    In one embodiment, not shown, the spraying device 32 for horizontal movement on the working platform 30 to a linear drive, which can be performed electromechanically, hydraulically or otherwise.
    FIG. 4 shows a module 40 of the work platform 30. In this case, it has first rectangular profiles 46 made of, for example, steel. At two ends of the illustrated module 40, second rectangular profiles 47, which have a smaller cross section than the first rectangular profiles 46, can be inserted. The inner surfaces of the first rectangular profile 46 form a defined fit with the outer surfaces of the second rectangular profile 47.
    From Fig. 5 it can be seen how the second rectangular profile 47 provides for the connection between the modules 40 of the working platform 30. The second rectangular profiles 47 are inserted into the first rectangular profiles 46 and are each fixed with four pins 48 or screws, which are secured, for example, with pins not shown. These pins 48 or screws are in the second rectangular profile 47 evenly divided between the two first rectangular profiles 46, which they are to connect.
    The support beams 15 are assembled according to the same scheme as the working platform 30 of several parts. In this case, first rectangular profiles 46 are also connected by second rectangular profiles 47, as in FIG. 5.
    In the embodiment shown in FIG. 6, the framework 10 has a support cage 50. This support cage 50 is attached to the underside of the work platform 30 in the middle of this between the two uprights 11 to protect the support cage 50 from vibration and the stability of the Scaffolding 10 does not affect. This is a reservoir 51 for the working fluid of the spray device 32. The spray device is connected via a hose 52 to the reservoir 51. By positioning the reservoir 51 in the support cage 50 at the bottom of the work platform 30 space is saved on this. Another advantage of this arrangement is that a lower moving load is guided on the work platform 30.
    Fig. 8 shows the measures required to avoid the spraying of the windows 4. During spraying of the building 1 from the first horizontal end position 35 to the second horizontal end position 36, a plurality of windows 4 occur.
    These can be detected by, for example, two inductive proximity sensors 37.
    When mounting the inductive proximity sensors 37, a certain distance between proximity sensors 37 must be considered. This distance should be the same size as the distance covered by the work platform 30 each on the way down. Therefore, in the illustrated embodiment, the spacing is carried out as follows: Spray width - 5cm = 35cm - 5cm = 30cm. The spray device 32 should be located between the two proximity sensors 37 and in the embodiment shown, the proximity sensors 37 are arranged at a distance of 3 cm around the nozzle of the spray device 32.
    It can occur during driving and spraying that only one proximity sensor 37 detects the window 4, which means that when the valve is closed, a part of the façade 3 is not painted. To avoid this, the two proximity sensors 37 are connected in series, so that the valve is only closed when both proximity sensors 37 detect the window 4. This use of two inductive proximity sensors 37 guarantees complete color coverage around the window 4. This would result in a portion of the window 4 being sprayed.
    In the illustrated embodiment, the spray width can not be changed. The spray angle in this embodiment is fixed and can not be changed. The spray width is determined by the angle of the spray nozzle and the distance to the house facade 3. The distance is in the illustrated embodiment 30 cm to the house facade 3. In order to avoid that the window 4 is sprayed, this can be covered with paper. It can be covered at the top and bottom 35cm, which corresponds to the spray width in the illustrated embodiment. From the descent of the working platform 30, which makes up 30 cm in this embodiment, it follows that the area sprayed on the window 4 is less than 30 cm. Whether and how much of the window 4 is sprayed depends on whether both proximity sensors 37 detect the window 4 or whether only one of the two proximity sensors 37 detects the window 4.
