Description

I. Field of application

The invention relates to a treatment vehicle, in particular cleaning vehicle, for the surfaces pointing to a roadway, in particular of tunnel walls. The following is therefore of a tunnel washing vehicle, without limiting the invention thereto.

II. Technical background

The walls of road tunnels need to be cleaned on a regular basis, as the natural cleaning by rain does not occur here, but large amounts of dirt are introduced into the tunnel through the passing vehicles.

In this regard, tunnel washing vehicles are known in which, for example on a Unimog or tractor as carrier vehicles one or two washing devices are mounted, each comprising a mostly multi-part, in particular telescopic, controllable cantilever arm with a rotating washing brush at its free end.

The washing brushes are then offset one behind the other in the direction of travel and clean in the direction of travel sections of the tunnel wall and possibly also the tunnel ceiling, which adjoin one another in the circumferential direction of the tunnel and usually overlap slightly.

Since the washing process especially in a tunnel - which often contains a lane reduction with respect to the feeding road - represents a particularly strong hindrance to traffic, the disadvantage of such z. B. two-arm tunnel washing equipment that by far not a whole half of the tunnel profile can be cleaned at once with a passage, but several passes are required.

A second aspect is the amount of entrained cleaning water or cleaning liquid: On a carrier vehicle such as a Unimog a water tank can be attached, which has a relatively small capacity, and often is not sufficient for a cleaning passage of a long tunnel, especially not if He should supply two or more washing brushes simultaneously with washing liquid.

In this context, tunnel washing devices based on trucks are known, for example from the EP 1544356 , which can carry a much larger tank for water or cleaning fluid because of the larger payload of the carrier vehicle.

A third aspect is the handling of the tunnel washing machine in use by the operator, who sits in the cab of the carrier vehicle and often at the same time the driver of the carrier vehicle is:
It depends on the good controllability and therefore also the visibility of the position of the individual cleaning heads relative to the tunnel wall.

III. Presentation of the invention

a) Technical task

It is therefore the object of the invention to provide a processing vehicle, in particular a tunnel washing vehicle, which has at least three working heads, in particular washing heads, which are individually adjustable and controllable and yet has good handling and a large supply of cleaning liquid.

b) Solution of the task

This object is solved by the features of claim 1. Advantageous embodiments will be apparent from the dependent claims.

Due to the arrangement of the cleaning devices, so their attachment point to the chassis, on the one hand in front of the cab, on the other hand in the space between the cab and water tank and further at the rear of the water tank attachment points are selected on the chassis, which are within the cross-sectional profile of the vehicle and not laterally In addition, as in solutions in which left and right of the water tank each have a boom attached.

Nevertheless, with the implements so mounted, either a surface to the left or right of the host vehicle - viewed in the direction of travel - can be machined by either having the boom arms long enough and fixedly mounted in the transverse center of the vehicle, or along a transverse transverse offset rail relative to the chassis of FIG can be moved left to right.

Even working on both sides of the carrier vehicle at the same time is thus possible, for example, by working the third implement on the left side, while the first and second works on the right side.

Seen in the longitudinal direction of the vehicle working in the longitudinal region in which its attachment point is located on the chassis of the vehicle, the work equipment is also a sufficient longitudinal distance of the working heads to each other in Work input achieved, so that they do not influence each other inadmissible and also the effect of each individual working head is immediately good to see and check.

A significant further advantage is that the weight is distributed over the length of the vehicle by the arrangement of the tools distributed in the longitudinal direction, so that none of the axes of the carrier vehicle is disproportionately loaded.

In order to spend the vehicle from one job site to another, the implements are folded into a transport position, where it matters that the implements hinder as little as possible in this transport position, so project beyond the cross-sectional profile of the vehicle to the outside.

Preferably, therefore, in the transport position, none of the implements is above the cross-sectional profile of the vehicle.

As a rule, the first, mounted in front of the front of the cab work implement a lying approximately at the same height portion of a side wall z. B. a tunnel wall, the second between the cab and water tank mounted implement, however, the lowest section, usually the boom must be the longest formed by the three work equipment and therefore may not be housed in the folded state within the cross-sectional profile of the carrier vehicle, or man would like to avoid the technical effort for such a close collapse of this boom.

As a result, the cantilever arm of this second, central working device is then placed in the transport position in the longitudinal direction aligned to the rear over the water tank, usually on a support bridge mounted above the water tank.

Even if the water tank is lower than the cab of the carrier vehicle, in this solution, the stored in transport position second implement is often in height slightly above the cab.

However, this is usually not a serious drawback, since the carrier vehicles do not have a high driver's cab and thus overall the vehicle in the transport position is still below the standard height for trucks and can drive through all tunnels in the rule.

The first and the third implement are moved for the transport position to one end of the offset rail in the transverse direction and then folded with their Auslegerarmteilen transversely to the direction of travel, so that the Auslegerarmteile and preferably also the working head, in particular brush head, transversely in front of or behind the vehicle are located.

In particular, the first and the third implement may be identical and differ only in their attachment to the vehicle.

The working head of the respective working device is preferably a cleaning head. This may consist of a rotary driven brush, which has a cylindrical shape in the rotating state, for example, which is preferably constantly wetted with cleaning fluid during use, or from a high-pressure spray bar, spray the nozzle with high pressure cleaning liquid directly on the surface to be cleaned or include both together, so a rotary driven brush and a high pressure spray bar.

Appropriate cleaning heads can be easily replaced at the free end of the boom depending on the purpose.

All tools together are preferably controlled by a total control, which is usually protected inside the vehicle, usually located in the driver's cab.

In order to facilitate the control of the total of three working heads relative to the surfaces to be cleaned, the controller has a learning function, based on the idea that the profile of the surfaces to be cleaned, such as the inner surfaces of a tunnel to be traveled, changes only slightly in the longitudinal direction.

For this purpose, the control for the implements on a learning function, in which - especially at standstill of the vehicle, but already in a working position to the surfaces to be cleaned - the individual working heads and thus cantilever arms of the implements manually in their optimal position on the be adjusted by her to be cleaned section of the wall.

This optimum position is stored in the controller, and mainly in their relative position of the three working devices to each other, possibly also in terms of their absolute position to the host vehicle.

In the subsequent work operation of the operator, who is either the passenger or the driver of the vehicle, only one of the working heads, which is well visible from him, usually the working head of the first implement, controlled relative to the surfaces to be cleaned, which anyway necessary if the carrier vehicle is not exactly the same distance from the z. B. tunnel wall drives or changes, for example, the height of the roadway relative to the tunnel ceiling or the like.

This actively controlled working head serves, so to speak, as a master working device and the other working devices and their working heads are automatically tracked by the control system analogously so that the relative position of the individual working heads is maintained relative to one another.

In order to minimize the contamination of the carrier vehicle itself and to be able to clearly see the work result, in particular the cleaning result of the working heads directly behind the working head, have at least the working head of the first implement, preferably all working heads on a protective cover towards the carrier vehicle down, the throwing away Water and dirt in particular z. B. allow by the rotating brush of a brush head only in the direction of the surface to be cleaned.

The contour of the rotating brushes can be cylindrical in the rotating state and, or deviating from the cylindrical contour, can be a barrel-shaped contour, as a result of which curved walls can be cleaned better.

For the same reason, a brush head of several, z. B. two adjacent, rotating brushes, in which the axes of rotation are not in line, but form an angle to each other, which is preferably adjustable, thereby adapting the brush head to the curvature of the wall to be cleaned.

For the control of the vehicle along the wall to be cleaned, a particular non-contact scanning sensor can be attached to the vehicle instead of the manual control, which scans on the ground, so the road, existing guidance lines such as the lane side line or the median strip of the road and the vehicle in the transverse direction relative controls.

In order for the sensor to have as little influence as possible on the dirt generated by the working heads, such a sensor is preferably mounted under the vehicle or on the side of the vehicle facing away from the cleaning side.

In order to use the carrier vehicle for other purposes than for wearing these tools, the implements are easily assembled and disassembled formed on the vehicle and preferably have a - in particular extendable or foldable - supporting device by which they after releasing the connection to the vehicle can easily be parked on a subsoil, for example in a warehouse, and stored temporarily.

A particular problem in the cleaning of road tunnels are the niches that exist at greater intervals in the tunnel wall, which serve as emergency stop bays for damaged vehicles.

Their z. B. Rear panel is much farther from the normal lane in the tunnel than the normal tunnel wall and therefore often needs to be cleaned separately by hand or with a special device, as the back panel side walls, floor and ceiling of these niches are not reached by a normal tunnel cleaner can or if, then only after consuming maneuvering the cleaning vehicle closer to the niche, which is very time consuming.

In the vehicle according to the invention, however, the boom and in particular its telescoping and the extension of the transverse offset rail is dimensioned so that the corresponding cleaning head by moving the boom on the cross-offset rail towards holding bay and additional extension of the telescopic arm and / or extension of the boom in position is to clean the holding bay, without the carrier vehicle must leave its normal lane and therefore does not have to rank.

In order to clean especially the side walls of such a holding bay and the ceiling and the floor, it may be necessary that the carrier vehicle stops next to the holding bay until these special tasks are performed, which means only a relatively short time overhead.

c) embodiments

Embodiments according to the invention are described in more detail below by way of example. Show it:

1a to 1c : The vehicle with working implements in working position in different views,

2a to 2c : the vehicle with the implements in transport position in different views,

3a , b: the vehicle when cleaning a holding bay.

All figures share the basic structure of the vehicle 1 which consists of a truck chassis 2 with a cab 1a , preferably without bonnet, and a large water tank mounted on the loading area 3 for water or other cleaning fluid, leaving between cab 1a and water tank 3 a sufficient distance to mount a working device 4b arises.

In the 1a to c, 2a to c are the implements 4a to c to cleaning equipment, each with a boom 5 , which consists of several articulated arm parts 5a , b, at least one of which may also be telescopic.

With one end is the boom arm 5 on the chassis 2 of the vehicle 1 attached and at the free end of the boom 5 is a brush head 6 fastened, in which a in the rotating state about cylindrical brush 12 , which is wetted by spray nozzles with cleaning liquid and in the drawings only in 1a on the implement 4 is shown on a rotationally driven shaft 16 is attached.

The relative position of the arm parts 5a , b to each other and to the vehicle 1 on the one hand and to the brush head 6 on the other hand is set and controlled by driven cylinder in between and changed if necessary.

The wave 16 is mounted on both sides in the base frame of the brush head, which preferably is centered at the free end of the cantilever arm 5 is attached.

One to the carrier vehicle 1 directed protective cover 8th Prevents cleaning fluid and dirt from rotating while moving the brush towards the host vehicle 1 injected.

The vehicle 1 carries three cleaning devices 4a to 4c of which the first cleaning device 4a in front of the front of the cab 1 attached to the vehicle, the second cleaning device 4b in the space between the cab 1a and tank 3 and the third cleaning device 4c at the rear of the chassis, behind the end of the tank 3 , is mounted.

In this case, the first and third cleaning device 4a . 4c be formed identical.

As in the supervision of 1b As can be seen, all three include cleaning equipment 4a to 4c a transverse offset rail 17 , along the chassis-side attachment point of the boom arm 5 in the transverse direction 11 can be moved between the left and the right edge of the profile of the carrier vehicle 1 , which is important both for the adjustment on the surface to be cleaned and for the adoption of the transport position.

In the 1a to c are the cleaning devices 4a to c in working position, where in 1a the first cleaning device 4a spaced apart from the chassis of the vehicle, that is, in a position released from the vehicle, is shown, but this is only to indicate the disassembly of the equipment, of course, in the use of work firmly with the vehicle 1 connected is.

The same applies to the 2 indicating the transport position of the implements and thereby the first and second implement 4a and 4b show dismantled.

In the working position of 1a to 1c the position of the implements is shown as necessary, if 1c the entire height of the tunnel wall and an adjoining area of the tunnel ceiling, ie a maximum of only one half of the tunnel profile, should be cleaned during a passage.

For right-handers this is the right side of the tunnel, which is why the boom arm 5 extended to the right, so at least the side wall processing boom arms 5 of the first and second implement 4a , b to the right over the cross-sectional profile of the vehicle 1 project out and her brush head 6 in contact with the wall to be cleaned.

In the 1a and 1b it can be seen that the extension arms 5 preferably protrude outwardly in a transverse plane at right angles to the direction of travel 10 of the vehicle 1 lies.

As 1c shows, cleans the brush head 6 the first, in front of the vehicle front mounted, cleaning device 4a not the deepest part of the wall, but a high-lying wall area 101b , Preferably the adjacent to the transition edge to the tunnel ceiling wall area, as this wall area the most accurate manual control of the brush head 6 requires and this brush head of the first implement 4a best viewed by the operator.

The lowest wall area 101 instead is from the second cleaner 4b edited while the third and rearmost cleaning device 4c - Depending on the height of the tunnel - either the uppermost height of the wall of the tunnel cleans or an area on the tunnel ceiling, for example, the adjacent to the tunnel wall area.

The corresponding brush head 6 this cleaning device 4c has in the presentation of 1c not quite reached his working position.

The 1a and 1b also show that in the direction of travel 10 the working heads, so here the brush heads 6 , at the second and third implement 4b . 4c from the free end of the cantilever arm 5 out in the direction of travel 10 behind it while at the first implement 4a the brush head 6 from the free end of the cantilever arm 5 protrudes forward.

The forward protrusion mainly serves the improved visibility of this brush head 6 through the cab 1a sitting operator.

The brush heads 6 may also be opposite the free end of the cantilever arms carrying them 5 be resiliently biased towards the surface to be cleaned.

As 1b shows, are the attachment points of the boom arms of the individual cleaning equipment 4a to 4c at their transverse offset rails 17 on in the working position different transverse positions.

While the boom arm 5 of the middle implement 4b is located approximately in the middle of the transverse offset rail, is the attachment point of the first cleaning device 4a Located slightly to the left of the center, that of the third, rearmost cleaning device 4c even on the left end of the offset rail.

Overall, however, the existing distribution in the transverse direction also gives a good weight distribution in the transverse direction, so that not the entire weight of the implements completely on the left or right side of the chassis 2 of the vehicle 1 in working mode loads.

The transport position of the implements 4a to c is in the 2a to 2c shown:
The boom arms 5 are transversely in front of the transverse offset rail in a vertical plane 17 and thus also in front of the front of the cab 1a or behind the rear of the vehicle 1 collapsed and extend in height from about the bumper height to the lower edge of the window of the cab 1a ,

The respective brush head 6 is in front of the folded boom 5 lying with the axis of rotation also extending transversely and is located in the same height range as the folded boom, which is the first, foremost cleaning device 4a concerns.

The rear cleaning device is the sequence in the direction of travel 10 analogously reversed.

The attachment points of the first and last cleaning device 4a and 4c are moved at opposite ends of the offset rail, so in this case the front cleaning device 4a on the left side and the rear cleaning device 4c on the right side.

In contrast, there is the attachment point of the middle cleaning device 4b in the middle of the offset rail 17 and the boom arm 5 runs in the longitudinal direction 10 centered to the rear in an almost extended position across the tank and is on a support bridge 18 filed over the tank 3 running away on the chassis 2 is mounted.

This brush head 6 stands highest in height above the tank 3 up in front and also slightly above the top of the cab 1 how best that 2c shows.

The total height of the vehicle in the transport position 1 nevertheless does not reach the maximum height specified for trucks, so that all tunnels can be passed through.

In width, put the cleaning equipment 4a to 4c in the transport position anyway no hindrance, since they are in the transverse direction 11 completely within the cross-sectional profile of the cleaning vehicle 1 are located.

The 3a and 3b show the situation of driving in the normal lane or stationary carrier vehicle next to a holding bay 102 in the tunnel, which also needs to be cleaned.

It is only the second, between the driver's cab 1a and tank 3 mounted cleaning device 4b for clarity, which is shown in 3a a brush head 6 carries and in 3b instead a high pressure spray bar 7 ,

The cleaning head of this second implement 4b is shown in several positions, once in the cleaning position for cleaning the normal tunnel wall, once in the transverse direction 11 Towards the back wall of the holding bay 102 further outward working position, once with the vehicle centered completely upright boom and once with on the tank 3 of the vehicle 1 behind the extended boom 5 ,

It can be seen that by moving the cantilever arm 5 this second cleaning device 4b on the cross offset rail in direction Rest Stop 102 and optionally additional extension of the telescoping of the boom 5 the cleaning head so far in the holding bay 102 can be driven forward in that he cleans the rear wall.

By appropriate pivoting of the cleaning head and the front and rear side wall of the retaining bay can 102 by transverse processes 11 be cleaned along this side wall.

The bottom of the holding bay is by appropriate lateral extension of the front, first implement, not shown 4a reached and cleaned, and the ceiling of the detention bay 102 by a correspondingly extended to the side and pivoted cleaning head either the second implement shown here 4b or the rear implement 4c ,
