Technical field

The invention relates to a mobile cleaning device of protective devices such as road barriers along roads such as streets, roads or squares.

BACKGROUND OF THE INVENTION

Such roads, such as streets, roads or squares, are regularly provided either in the lateral edge area and / or in the central belt area with protective devices / barriers which are also usually oriented in the longitudinal direction, i.e. j. in the direction of orientation of the respective communication and are realized as essentially continuous. In this context, the term 'essentially' includes the fact that the respective crash barriers may be stacked together of individual elements arranged consecutively in the longitudinal direction and may have more or less wide gaps or breaks.

Exemplary cross-sections through various construction devices of protective devices / crash barriers are known. These can be formed as expanded in the lower shoulder area. The lateral surfaces of the protective devices / barriers shown may be substantially smooth or may have protrusions or profiling. Furthermore, other devices such as reflective elements or the like may be located in the side area of the protective devices / barriers shown.

Especially in rainy weather and winter, such barriers are heavily polluted, which on the one hand is unsightly, but on the other hand it also compromises traffic safety, since reflective elements usually located in the area of these barriers no longer fulfill their safety blow due to pollution. Additional cleaning of reflective elements and protective devices / crash barriers may also be necessary as a result of construction activity and communication with the respective contamination

In addition, intensive soiling can have a negative impact on the life of the protective device / crash barrier, for example if it is made of steel or comparable materials. Furthermore, in the case of portable protective devices / barriers, contamination adversely affects the maneuverability, in particular the dismantling of such protective devices / barriers. Therefore, there is a need for a cleaning device which is useful for cleaning said protective devices / crash barriers, and in particular the night vision reflective elements. It is an object of the invention to provide such a cleaning device.

SUMMARY OF THE INVENTION

The object of the invention has been solved by a mobile cleaning device with the features of claim 1. Advantageous further embodiments of the cleaning device according to the invention are the subject matter of the claims, the text of which is hereby expressly incorporated by reference.

According to the invention, the mobile cleaning device for protective devices / road barriers on roads, streets, roads or squares, in particular substantially continuous barriers oriented in the longitudinal direction, comprises a supporting structure, the supporting structure being designed and designed to extend over the clean protective means bridge equipment and barrier. Further, on the support structure, mobile means for moving the cleaning device as well as cleaning means are arranged, wherein the cleaning means are designed to act on the side of the protective device / guardrail during the driving of the cleaning device for cleaning purposes or for cleaning of other devices placed thereon. are reflective elements or the like, from contamination. "Side" here means from one or more sides.

Since the cleaning device according to the invention is designed to be mobile, it can be moved in a simple manner along the described protective device / safety barriers in order to clean them from dirt. In particular, the implementation of the bridge structure of the load-bearing structure will create extraordinary stability. In addition, it is possible in this way to provide a cleaning effect on both sides of the protective device / barrier.

A first further embodiment of the cleaning connection proposes that the traveling means are designed to be at least partially and / or temporarily driven or driven, so that the cleaning device is substantially independently movable. However, within the scope of the present invention, it is proposed that the vehicle means be at least temporarily releasable or idle so that the overall cleaning device can be towed or towed, for example by means of a corresponding accompanying motor vehicle.

A particular further embodiment of the cleaning device according to the invention proposes that the traveling means comprise at least one wheel, disc, roller, crawler chain or caterpillar belt on each side of the support structure. Any non-limiting combination of said means of movement is also possible. In principle, it is also within the scope of the invention to place the respective mobile means on only one side of the load-bearing structure and, respectively, on one side of the protective device / barrier, provided that safety of movement is not adversely affected.

N K 288606 B6

Another further embodiment of the cleaning device according to the invention proposes that the support structure be designed with the possibility of adjusting its height and / or width. The same applies to the mobile equipment mentioned above.

Yet another further embodiment of the cleaning device according to the invention suggests that the cleaning device has first guiding / control means which are designed to cooperate laterally with the protective device / barrier for the purpose of moving the cleaning device or for bringing it at a predefined distance with regard to protective devices / safety barriers. Said first guiding / steering means may be formed in the form of a plurality of discs, of which at least one disc, more preferably with a disc axis substantially in a vertical orientation, may be formed as driven or idling. Here, the set of disks can be configured with adjustment for the remainder of the cleaning device, in order to adapt the cleaning device in particular to differently formed crash barriers.

Again, another further embodiment of the cleaning device according to the invention proposes that it has second guiding / control means which are designed to act from above together with a protective device / barrier, for example with a flat surface of the protective device / barrier. Also, the second guiding / steering means may be implemented as a set of discs in which at least one disc is driven or idling. Also this set of discs can be adjustable with respect to the rest of the cleaning device in order to be able to adapt the cleaning device in particular to various high protective devices / crash barriers. In particular, said set of disks comprises two consecutive disks.

In any case, it can be ensured that the cleaning agents are made adjustable with respect to the rest of the cleaning device.

In another preferred further embodiment of the cleaning device according to the invention, it can be ensured that the cleaning means is driven, preferably asynchronously on different sides of the support structure, in order to optimize the cleaning effect depending on the direction of travel of the cleaning device. Here, the drive directions of the cleaning agents can be freely switched depending on the situation.

In order to operate the cleaning device according to the invention independently of external supply devices, a particularly advantageous further embodiment suggests that the cleaning device comprises a substantially autonomous supply of water and an effective cleaning agent, for example in the form of a co-drawn container. The active ingredient may be a chemical additive or a detergent.

For the same reason, the cleaning device may, in another embodiment, comprise a substantially autonomous energy storage device, more preferably electric power, particularly advantageous for supplying the drive of the traveling means and / or the cleaning means. However, the device according to the invention is not limited to an electric drive, but embodiments with combustion drives and corresponding fuel reservoirs (tanks) are also contemplated.

Again, another embodiment of the cleaning device according to the invention suggests that the cleaning agents comprise at least one pumping means in effective connection with the deposition means, more preferably nozzles or the like, for water and / or the cleaning agent. Said coating compositions can serve, on the one hand, to wet detergents (brushes) and, on the other hand, to directly clean the protective device / barrier (pre-cleaning or high-pressure cleaning).

Further, the cleaning device may comprise a coupling means for connection to an accompanying vehicle or the like, wherein the coupling means more preferably serves to supply water and / or active means and / or energy, particularly preferably during operation of the cleaning device.

The cleaning device may also have suitable devices to which the accompanying vehicle can be coupled for towing or towing the cleaning device.

More preferably, it is proposed that the total weight of the cleaning device, preferably without water supply and active agent, does not exceed about 70 kg, so that the cleaning device can be lifted by two persons through cleaned protective devices / barriers in order to be subsequently cleaned.

More preferably, the overall width of the cleaning device is less than or equal to the width of the guard / barrier including the two-way safety margin prescribed by the critical points. In this way, the cleaning device can also be used on roads, such as roads in particular. In this connection, the cleaning device has, in another embodiment, at least one signaling device for indicating the cleaning device, in particular in the normal operation of the cleaning device.

In a particularly advantageous further embodiment of the cleaning device according to the invention, it is proposed that at least the running means and / or the cleaning means be cable or cordless.

S K 288606 B6 controllable, more convenient radio. In this way, the cleaning device can be used in a particularly flexible manner.

As already mentioned, an embodiment of the cleaning device according to the invention assumes that belt or chain constructions are used as mobile means. These can be arranged in the form of a separate traveling unit approximately in the middle of the length of the cleaning device, since they have a relatively long sliding and running surface, and in this way they can replace the end wheels and disks of the cleaning device.

The control shall comprise at least the start, stop, forward, reverse commands as well as the various speeds of the journey.

The brush speed can be adjusted to the speed of the cleaning device. The same applies to the brush rotation direction.

Water and the active agent may be stored separately and mixed only immediately prior to use. However, a pre-formulated mixture and appropriate storage are used in the present invention.

In particular, the supporting structure of the cleaning device according to the invention can be made of suitable profiles or sheets self-supporting of steel, aluminum or the like.

Said traveling, drive and guide discs may comprise running surfaces of rubber, plastic or the like.

Said signaling device may be mounted on the cleaning device at the rear and centrally vertically, this may in particular include traffic signs, light arrows or other comparable warning devices.

DETAILED DESCRIPTION OF THE INVENTION

Figure 2 shows a front view of an embodiment of a cleaning device according to the invention, which is indicated as a whole. The cleaning device 1 is intended for cleaning road protection devices / barriers 2, such as streets, roads or squares, in particular for cleaning substantially continuous barriers oriented in the longitudinal direction. Such a barrier is shown schematically in Figure 2. The barrier 2 may be made of concrete, steel or other suitable material or combination of materials. On its outer side surfaces 2a, the barrier 2 has a reflective device or reflective elements 2b for improving the visibility of the barrier 2, especially at night. Such barriers 2 are known to the person skilled in the art, so there is no need to explain them further in the present case.

The cleaning device 1 initially comprises a support structure 3 which is designed as a bridge and has a U-shaped cross-section and serves to extend over the crash barrier 2 as shown. The support structure 3 at the ends of the free arms 3a of the support structure 3 The U has movable means in the form of wheels 4, so that the overall cleaning device 1 is movable or movable. In addition, the cleaning device 1 comprises brush-like cleaning agents 5 which are approximately cylindrical in shape and has a vertical axis of rotation 5a in operation, so that they can rotate sideways on the barrier 2 for cleaning purposes, in particular lateral surfaces 2a and reflective elements 2b. from pollution.

On the lateral arms 3a of the U-shaped structure 3, horizontal traveling, guide and drive wheels 6 are arranged at different vertical positions, each with a vertical axis of rotation 6a, the wheels 6 abutting against the crash barrier 2 in the area of the side surface 2a. The wheels 6, like the wheels 4, may be designed as free-running or at least partially driven or driven, in order to form a cleaning device 1 self-propelled along the barrier 2.

Furthermore, on the central arm 3b of the supporting structure 3, a further traveling and driving wheel 7 is located in the region above the crash barrier 2, which has significantly enlarged dimensions compared to the wheels 4, 6. The wheel 7 acts through its sliding surface together with the upper side 2c of the crash barrier and can also be designed as free-running

S K 288606 B6 and / or driven or driven - depending on whether the cleaning device I is self-propelled or driven by a foreign force.

In the embodiment shown in FIG. 2, a housing 8 is placed behind the upper wheel 7 on the support structure 3, which also extends as the support structure 3 in the plane of the figure. As will be pointed out further, in particular from the description of Figure 4, the support structure 3 also has a longitudinal extension extending into the plane of the figure and in this context preferably comprises at least two U-shaped arrangements with consecutive arms 3a, 3b in a convenient manner - more preferably sufficiently rigidly connected to each other, as shown in Figure 4. In the region above or between the said U-shaped arrangements of the support structure 3, a housing 8 is already provided, which serves to accommodate the wheel drives or drive devices 4, 6, 7, brushes. 5 for storing the control units for operating the cleaning device 1 as well as for storing water supplies and / or other cleaning agents. The wheels 4, 6, 7 and / or the brushes 5 are preferably adjustable with respect to their orientation and arrangement. Here, the wheels 4 are preferably formed with height adjustment, while the wheels 6 are preferably formed with adjustable height at least with respect to the lateral spacing from the arms 3a of the supporting structure 3 or the crash barrier.

2. The arms 3a of the support structure 3 may be formed with the possibility of turning and / or changing the height in relation to the arm 3b. as shown in Figure 5. For this purpose, the respective joints indicated by 3c are used.

As already indicated, the cleaning device 1 can be adapted to slide independently along the crash barriers by using at least partially driven wheels 4, 6, 7. However, it is also possible that the cleaning device 1 with the freewheels 4 can be unrestricted. , 6, 7 has been moved along the crash barriers 2, i. j. drawn or printed.

In the housing 8, a suitable energy storage device is further provided which provides the necessary energy to drive the wheels 4, 6, 7 and / or brushes 5. Depending on the drive units present, more preferably electric motors or internal combustion engines, the energy storage device is realized as an electric energy storage device. - battery or fuel tank for combustion - petrol or diesel.

As already mentioned, the housing 8 may include means for storing a supply of water and / or other suitable cleaning active medium. In this way, the cleaning device 1 is largely autonomous or self-sufficient in operation. However, the invention is in no way limited to such an embodiment: rather, it is also possible for the device 1 to be supplied with water and / or a cleaning active medium via e.g. hose distribution from accompanying vehicle. The same applies with respect to the power supply for the aforementioned drives and drive units.

Furthermore, nozzles or other cleaning agents which are not shown in FIG. 2 can be placed on the support structure 3. These nozzles serve, on the one hand, for wetting the brushes 5 and, on the other hand, for a direct cleaning effect on the barrier 2.

By means of the already discussed possibility of adjusting both the wheels 4, 6, 7 and the supporting structure 3, as well as the brushes 5 and respective brush axes 5a, it is possible to adapt the cleaning device 1 to different cross-sections and to create crash barriers 2 as shown in Figure 1. 3 schematically illustrates another embodiment of the cleaning apparatus 1 '. At this point, however, it should be noted that the embodiment of Figure 3 can also be used in combination with the described embodiment of Figure 2; in particular, the embodiments shown in Fig. 2 and Fig. 3 may be used sequentially in a single cleaning device to form a single complex cleaning device. In principle, any number of units shown in Figures 2 and 3 or cleaning devices T

In all figures, the same reference numerals designate the same or at least equally acting elements.

The supporting structure 3 according to Figure 3 is in principle designed in the same way as the supporting structure 3 according to Figure 2. It is noticeable that, according to Figure 3, no wheels - traveling or driving wheels 4 - are located in the region of the free ends of the arms 3a. 3 is preferably used in combination with the cleaning device j or the unit according to FIG. 2. Accordingly, according to FIG. 3, no upper wheel - traveling or driving wheel - is used above the center arm 3b of the supporting structure 3.

A further difference between the embodiments of Fig. 2 and Fig. 3 relates to cleaning agents or brushes. According to FIG. 3, they are designed as round (in a respective top view) brushes each with a horizontal axis of rotation 5b which, in the manner shown, act on the side surfaces 2a of the crash barriers 2 - approximately as brushes for motor vehicle wheel rims in car washes.

Approximately instead of the lower wheels 4 according to Figure 2, cylindrical brushes 52 with approximately a horizontal brush axis 5c, which laterally extend to the lateral surfaces 2a of the crash barriers 2, are additionally mounted on the supporting structure 3 according to Figure 3 in order to clean the ground reflectors of the crash barriers crash barriers 2 not recognizable in Figure 3.

With respect to the brush drive 5, 52, the principle already mentioned in Figure 2 applies in principle. This also applies to other possible devices in the area of the supporting structure 3.

N K 288606 B6

Figure 4 shows a side view of a special embodiment of the cleaning device Γ according to the invention which, at reference numeral I or at the reference numeral 1 ', comprises cleaning unit units as shown in principle in Figure 2 or Figure 3. First, the cleaning device 1 approximately as shown in FIG. 2 and then the cleaning device 1 as shown in FIG. 3 and finally the cleaning device 1 again as shown in FIG. 2. Here are the vertically oriented arms 3a of the respective supporting structures 3 (see figures 2 and 3). ) connected to each other by the horizontal and lower horizontal struts 3d.

Referring to Figure 4, two upper traveling and driving wheels 7 are arranged one after the other in the front and rear units 7. Among them is the aforementioned housing whose "inner life" is not explicitly shown. In this regard, reference is made to the foregoing and the description below.

The side wheels 6 are preferably arranged or height adjustable so as not to interfere with the side reflective elements 2b of the barrier 2.

In the lower zone of the crash barriers 2, at side reference number 2d, a laterally extended installation area is recognizable in which the above mentioned ground reflectors can be located. The cleaning device 1 'shown in FIG. 4 is shown, but does not have the lower brushes V shown in FIG.

With respect to the housing 8, according to FIG. 4, it has a symbolic distribution and is thus divided into a first section 8a and a second section 8b. By way of example, the drive units already mentioned are located in the first section 8a of the housing 8, which may be designed, for example, as hydraulic drive units with an electric power supply via an accumulator or from an electric aggregate. Alternatively, it is also possible to design with electric motors, also with an accumulator or an electric aggregate

The cleaning device is not restricted with respect to the drive device and can also be oriented in particular in the opposite direction against the arrow F. The corresponding principle also applies to the direction of rotation of the brushes 5, 5, 5y. units, such as a gasoline or diesel internal combustion engine.

The housing or section 8b in the illustrated embodiment serves to accommodate a water pump and / or other suitable cleaning active medium and to be connected to an external power supply without being limited to the present invention. Of course, the cleaning apparatus 1 'of Figure 4, as well as the cleaning apparatus 1a' of Figures 2 and 3, may be implemented as substantially self-sufficient and maintain their own supply of water / active media such as chemical additives and the like.

The use of two wheels 7 in succession in the upper region of the device serves to overcome the spaces between two individual not shown crash barrier elements 2. Through the illustrated arrangement it is ensured that at least each of the wheels 7 arranged in pairs - in automatic operation of the device 1 - has contact with the upper side 2c barriers 2 so that the device 1 can move forward in the direction of the arrow F.

Figure 5 emphasizes the aforementioned possibility of adjusting the support structure 3 according to Figures 2 and 3 by using the joints 3c between the central arm 3b and the free, lateral arm 3a of the support structure 3. Due to the possibility of rotating the free arm 3a in relation to the center arm 3b so that a correspondingly larger width B is produced in the lower region of the load-bearing structure, so that the corresponding cleaning device can be adapted, in particular, to crash barriers 2 with an enlarged cross-section in the lower region, see Figure 1.

The reference numeral 3e indicates the height adjusting device still present, in the specification the extension or the shortening of the free arms 3a, so that a wide adaptation to the different barrier geometry 3 can also take place in this area.

Figure 6 shows different brush forms with respect to brushes 5 shown in Figure 2 and Figure 4. Here, the brush shown at the far left of Figure 6 essentially corresponds to the brushes 5 of Figure 2; the illustrated brush 5 has an approximately round shape. The brush 5 in the central part of Figure 6, unlike the first, is designed as a truncated cone, with the brush diameter tapering continuously towards one end. The brush 5 in the right part of Figure 6 is formed of individual brush elements 5d with different possibly variable brush diameters, which are arranged one after the other on the common brush axis 5a.

In particular, by means of the brush 5 according to the right partial representation in FIG. 6, a complete flexible adaptation to a given cross-section of the barrier 2 can be achieved.

In contrast, the use of the brushes d 'shown in Figure 3 and Figure 4 is only meaningful for crash barriers with substantially smooth, planar side faces, see in particular the barrier 2 according to the top row in Figure 1.
