Description

The invention relates to a device for a road vehicle, the device comprising at least one attachment having a device holder and attached to the device holder devices which are displaceable on the device holder at least transversely to a predetermined direction of travel of the road vehicle and of which at least one is a Senkkastendeckelheber wherein at least one of the devices attached to the device holder is a mud-trap cleaner, the mud-trap cleaner having a suction tube carried on the device holder, and wherein the sink cap lifter and the mud trap cleaner form a road drain cleaner.

Activities that are carried out with appropriate additions to road vehicles, often concern construction, repair and maintenance work. Annexes for recurring maintenance work, for example, sweeping devices for cleaning lanes, roads and other paved surfaces, such as marketplaces, sidewalks or pedestrian areas, be, with the sweeping devices only a superficial cleaning is possible. With surface water in road drains, which are also referred to as inlet grate, rainwater inlet, gully, sink or caisson, rinsed impurities accumulate even with regular cleaning of the surfaces in appropriate sludge traps of the street drains, so that the street drains must be cleaned separately at regular intervals , These sometimes physically heavy jobs then require one Relatively large manpower and time, as each road has to be cleaned individually and by hand.

Such a device for a road vehicle, with the dirt traps of road drains to be cleaned, goes out of the DE 10 2014 022 121 A1 out. In this should be provided on a narrow side of the device receiving vehicle a laterally extendable cross member on which a control pulpit is arranged, which is accessible by an operator. Standing on the control pulpit, a lid lifter and a suction line corresponding to the sludge trap are manually pivotable about a vertical axis by the operator, with the lid lifter and the suction line each supported on outriggers. These booms are successively pivoted when cleaning a street drain to first raise the Senkkastendeckel with the Senkkastendeckelheber, wegzuverschwenken the Senkkastendeckel, clean the dirt trap with the suction line and then set down the Senkkastendeckel again.

The object of the invention is to provide such a device in order to be able to clean street drains in a simple manner faster and more cost-effectively with less personnel expenditure.

This object is achieved by a device having the features of claim 1 and a road vehicle according to claim 20. Further developments and advantageous embodiments are named in the respective subordinate claims.

The device for a road vehicle, the device comprising at least one attachment having a device holder and attached to the device holder devices which are displaceable on the device holder at least transversely to a predetermined direction of travel of the road vehicle and of which at least one is a vertical box lid lifter, wherein According to the invention, at least one of the devices attached to the device holder is a mud-trap cleaner, wherein the mud-box lid cleaner and the mud-trap cleaner form a road-drain cleaning device, characterized in that at least one lid-locking device is associated with the countersunk lid lifter, and in that the lid-locking device can be guided past the vertical box lid lifter, at least in sections, or that the lid-latching device can be inserted into a horizontal area at least in a partial area below a horizontal span formed by the vertical box lid lifter.

The cover latching device is therefore on the one hand suitable and designed a folding Senkkastendeckel which is connected via a hinge fixed to the rest of the caisson after it has been raised with the Senkkastendeckelheber, unfold so far that the suction pipe of the device can be inserted into the street drain to the Clean the street drain with the intake manifold. The Senkkastendeckel previously raised with the Senkkastendeckelheberel is thereby pushed away by pressing the lid latching device, which is passed below the Senkkastendeckelhebers from the lid pressing device such that the Senkkastendeckel remains in an unfolded position, in particular due to its own weight in the unfolded position remains without the Senkkastendeckelheber or hold the lid latching device during cleaning of the box cap.

Alternatively or in addition to the above-mentioned function, to fold over an already partly raised countersunk box lid with hinge, the lid pushing unit can on the other hand also be used to unlock a lock of a countersink box lid. Such a lock can be formed, for example, in that a partial section a grid or other part of the Senkkastendeckels with an undercut of a skirt of the Senkkastendeckels is engageable. In order to unlock the lock, the lid locking device can therefore also be designed such that it can be inserted into a gap or a recess of the countersunk lid. With the inserted into a gap or a recess of the Senkkastendeckeld lid pressure device can then be applied against the locking forming portion or part of the Senkkastendeckels pressure.

In particular, in countersunk box hinges according to an advantageous embodiment, a lateral pressure is exerted in a horizontal plane. The pressure against the section or the part of the Senkkastendeckels then solves the lock between countersink cover and enclosure of the Senkkastendeckels, in particular by the portion or part of the Senkkastendeckels is pushed out of the undercut. In such countersunk covers or gullies, which are clamped or otherwise locked, the lid latching device can also attack from the bottom of the Senkkastendeckel and push this Senkkastendeckel up to release the lock or clamp. A clamp may be formed, for example, by the fact that two sections of the Senkkastendeckels spread, that is pressed apart, must be in order to release the lock of the Senkkastendeckels. Combinations of the aforementioned movements of the lid latching device for releasing a lock are also possible.

Since the lock is released prior to lifting the countersink lid, advantageously less force must be expended when lifting the countersunk box lid. This comes in particular to bear in mind that the often grid-shaped countersunk lid to have less mass to be able to be raised with a magnetic countersunk lid lifter can. In addition, when pulling or pushing the countersink cover from below much higher forces are applied to the countersink cover than, for example, only with a magnet, the higher forces are sufficient to solve a mostly provided as a locking latch connection or snap connection alone by pulling or pressing from below to the Senkkastendeckel. Also, a Senkkastendeckelheber example forming magnet can be designed correspondingly weaker, so that a more cost-effective construction of the device is possible.

In particular, for the function of releasing a locked countersunk lid, it is usually not necessary to pass the lid latching device below the sinker lid. It is usually sufficient if the lid latching device can be guided or guided into at least a partial area below a horizontal plane spanned by the vertical box lid lifter. Under hineinführbar are to be understood in the broad sense of all lid locking devices that can attack below the spanned by the Senkkastendeckelheber, horizontal plane on the Senkkastendeckel.

According to an advantageous embodiment of the invention, a cover pressing device can also be provided for both functions or uses, or a device can have two cover pressing devices which each fulfill one of the functions.

The lid latching device associated with the countersunk lid lifter can either be arranged and fastened to the countersunk lid lifter or also fastened to the appliance holder. Depending on the attachment of the lid latching device to the device, different shapes of these are suitable in order to be able to optimally engage the raised box lid to be lifted or lifted. Furthermore, the position of the attachment also different directions of movement and Motion forms of the cover pressing device condition, for example, a pivoting or a pushing movement of the lid pressing device.

In a further embodiment, the cover pressing device can be formed by a bracket, hook, slide, a rod or the like arranged movably to the countersink lid lifter. The further embodiment of the lid latching device is also dependent on the function of the lid latching device, so that, for example, a bracket or a slide are more suitable for opening a Senkkastendeckels with hinge and a hook is particularly advantageous when releasing a lock a Senkkastendeckels.

All embodiments or embodiments of the lid latching device, which are intended in particular to open an already partially raised Senkkastendeckel in an open position, in common is that they all have a below the Senkkastendeckelhebers vorbeiführbaren cover abutment section, which preferably extends in the horizontal direction and against a raised, hinged Senkkastendeckel is depressible. For this purpose, the cover pressing device, in particular with the cover abutment section is preferably moved from a first side of the Senkkastendeckelhebers to an opposite side of the Senkkastendeckelhebers.

The cover pressing device can, if this is arranged on the Senkkastendeckelheber, be hinged on one side or on both sides of the Senkkastendeckelheber.

Preferably hinged on one side of the Senkkastendeckelheber is the lid latching device, if this is to be used to open a lock a Senkkastendeckels. Since this cover latching device does not have to fold away or fold down the entire countersink cover, the cover latching device can be designed such that the Cover locking device can be pressed only in a portion below a spanned by the Senkkastendeckelheber, horizontal plane with a hook, a rod or the like against a locking forming portion or part of the Senkkastendeckels. The cover abutment portion does not necessarily have to be moved below the countersink cover, in particular from a first side to an opposite second side, wherein a passing of the lid locking device below the countersunk lid is also possible for the function of unlocking, especially when the lid locking device combines both functions together.

As a lid abutment portion may be provided for unlocking lid pressing device, in particular the hook or the rod of the lid pressing device, at its free end have a one-sided or two-sided or multi-sided projection. By the projection an improved guidance of the subsection or part of the Senkkastendeckels is reached at which the cover pressing means for unlocking attacks, so that the Senkkastendeckel advantageously not only can be pressed but also pulled. A projection formed on both sides or on more than one side at the free end also has the advantage that different latches can then be opened in different directions with the lid latch device.

Alternatively, the lid locking device, in particular for releasing a lock, may also be formed by a rod or a hook, which are under tension by means of a spring such that they protrude into the region below the horizontal plane formed by the countersunk lid. Preferably, the spring-loaded lid latch is vertically aligned. The rod or hook may then be inserted and hooked into a recess or grid of the locked countersink lid. By pulling or pushing down, the lock of the countersunk box lid is released by the Lower box lid lifter is raised. When attaching the preferably designed as a magnetic Senkkastendeckelhebers to unfold the Senkkastendeckel, the rod is then pressed against the spring tension upwards, so that a magnet over the entire surface of the Senkkastendeckel can be attached.

According to a first preferred embodiment, the lid locking device is pivotable about a horizontal axis of rotation transversely or longitudinally to the direction of travel of the road vehicle. This first embodiment allows a particularly simple attachment to the Senkkastendeckelheber and a particularly simple control of the lid latching device, for example via a chain drive or belt drive, which may be driven by an oil motor or electric motor.

Alternatively, suitable as a drive hydraulic cylinder or Pneumatikzyl indians.

According to another, second embodiment, the lid locking device is displaceable in a horizontal plane transversely or longitudinally to the direction of travel of the road vehicle. With the displaceable design is achieved that the lid latching device with advantage always with the same distance to the Senkkastendeckelheber acts on the raised, hinged Senkkastendeckel, which allows less accurate positioning of the Senkkastendeckelhebers on the road.

While the pivotable cover pressing device is preferably arranged directly on the Senkkastendeckelheber, a displaceable in a horizontal plane lid pressing device is preferably attached directly to the device holder.

In a further embodiment, the lid locking device can also be displaced between the transverse or longitudinal direction of the road vehicle or be pivoted pivotable position. A pivotable between transverse and longitudinal to the direction of travel of the road vehicle lid pressure device has the advantage that both such Senkkastendeckel about a rotation axis at right angles to a curb or transverse to a direction of travel of the vehicle with the device, as well as such Senkkastendeckel around an axis of rotation along a Curb or the direction of travel with a common, single lid latching device and Senkkastendeckelheber be lifted and hinged.

A transverse or longitudinally to the direction of travel of the road vehicle displaceable or pivotable lid locking device may also be particularly suitable to combine both the function of opening a raised Senkkastendeckels and the opening of a lock a Senkkastendeckels each other in a lid latch. This is particularly true since the engaging in a locking portion or part of the Senkkastendeckels is usually fixed to an undercut of a skirt of the Senkkastendeckels, which is arranged at right angles to a pivoting plane of the Senkkastendeckels with hinge. In a further embodiment, a lid-locking device combining both functions can also have at least two different cover abutment sections, wherein the different cover abutment sections are adapted to their respective function.

If the two functions are associated with two different cover-latching devices of the device, the two cover-latching devices advantageously have displacement directions or pivoting directions arranged at right angles to one another, in particular in the horizontal plane at right angles to one another.

According to a preferred embodiment, the cover pressing device consists of a hook and an actuating cylinder associated with the hook. Next, the actuating cylinder advantageously allows pivoting of the hook transversely to the direction of travel according to a mounting position of most countersunk lid and locks this. To intercept forces occurring when unlocking the hook and to protect the actuating cylinder against damage, a stop may continue to be arranged on the Senkkastendeckelheber. By the stop then a maximum possible deflection of the hook is limited so that the operating transmitter is protected against damage.

In addition to such Senkkastendeckeln that are hinged or locked, the execution of Senkkastendeckelhebers when not operating the lid locking device also allows lifting and pivoting of the raised Senkkastendeckels with the Senkkastendeckelheber if the Senkkastendeckel is not designed to fold. The lid locking device is arranged in a starting position such that it is arranged laterally to the Senkkastendeckel and the area below the Senkkastendeckelhebers is free.

In order to minimize the need to maneuver with the road vehicle and to allow easy starting of road courses, it is provided that the Senkkastendeckelheber is rotatably supported, in particular infinitely rotatable in at least one direction, on the device holder. This is supported on a vertically aligned shaft and can rotate about a vertical axis and preferably by means of a hydraulic motor driven, that is rotated, be. Road accesses that are difficult to access in curves or other non-straight road sections can then also be approached obliquely with the road vehicle having the device, and the countersunk lid lifter can be aligned at the position of the road run by rotating it.

In addition, it is possible to achieve the greatest possible independence of the countersunk box lifter from the shape of the road drainage by at least this a magnet, in particular at least one hydraulically actuated permanent lifting magnet or at least one electromagnet. The permanent lifting magnet is a particularly cost-effective and easily hydraulically or pneumatically controllable with a cylinder solution in which a permanent magnet is moved with the cylinder in a box. Instead of a hydraulically actuated cylinder, the permanent lifting magnet can also be moved via an oil motor or an electric motor or the like by means of an eccentric rod. Alternatively, the electromagnet to be provided is easily switched on and off electrically. In addition, when using an electromagnet less mechanical parts are needed and it can be a smaller, that is operated with a lower oil content, hydraulic system can be provided. Instead of a magnet, the countersunk lid lifter may also have a gripper or a claw, with which or which is gripped in the lattice-shaped upper part to lift the Senkkastendeckel.

In a further embodiment, the Senkkastendeckelheber or its magnet can be tilted so that it can be optimally adapted to curved roads or surfaces. For this purpose, the countersink lid lifter has an adjusting device with a spindle, which can be actuated, for example, by an electric motor or a hand crank.

In connection with the tiltable Senkkastendeckelheber also the Senkkastendeckelheber itself or its magnet can form the lid latching device. A folding Senkkastendeckel which is connected via a hinge fixed to the rest of the sinker is then raised directly with the Senkkastendeckelheber or its magnet and pivoted so that this remains for cleaning in the unfolded position, in particular due to its own weight in the unfolded position remains , A safe guidance of the countersunk box cover is by the tiltable Countersunk lid lifter, in particular the countersunk lid lifter which can be tilted by at least 90 degrees. If the countersunk lid lifter has a magnet, in a preferred embodiment the countersink lid is only released from the magnet after the countersink lid has been pivoted into the unfolded position.

After the countersink jack has been positioned above the pavement, it must be lowered to lift the countersink lid. For this purpose, the Senkkastendeckelheber and the sludge trap cleaner are advantageously raised with a common hoist, the hoist is assigned to the cultivation. Through the combination of countersunk lid lifter and sludge trap cleaner, street drains can be cleaned without a worker having to lift a countersunk lid by hand or hand-hold the sludge trap cleaner. Under a Senkkastendeckel is understood a mostly latticed, cast iron upper part of the road drain, which can be raised or removed for cleaning and control purposes and is often referred to as manhole cover. The device is then moved with the Senkkastendeckelheber to above a Senkkastendeckels a street drain, recorded the Senkkastendeckel with the Senkkastendeckelheber, raised and pivoted or moved until the suction pipe of the sludge trap cleaner can be inserted into the street drain or its downcomer. The Senkkastendeckel is at least as far laterally moved away from the street drain until its opening is completely freely accessible from above over its entire surface, that is free of their entire cross-section. The fact that both the Senkkastendeckelheber and the mud trap cleaner are attached to a common device holder, the cleaning of the streets after the road vehicle has been brought into position, carried out largely automated, the movements of the Senkkastendeckelhebers and the mud trap are matched.

The attachment according to the invention to the road vehicle designates the part of the device which can be attached to an interface of the road vehicle and forms the device. Depending on the road vehicle, the interface may be standardized, for example, a device mounting plate, a three-point suspension or the like, or be customized by taking advantage of existing on the road vehicle lifting and / or displacement device or other substructures.

Depending on the road vehicle, when the device changes, it may be necessary to adapt it to the road vehicle, possibly having to realign the devices. The device holder or a part of this may have for this purpose in elongated holes guided bolts, in particular bolts, with which the device holder or at least the part with the devices to a suspension or interface of the road vehicle or to the road vehicle can be aligned.

The device holder or at least one of the devices in a preferred embodiment, parallel to a footprint of the road vehicle on which the attachment is fastened, displaced. It is thus achieved that the device or the device holder can be guided over the contact surface with as constant a distance as possible, so that the device can be assigned a uniform, identical stroke regardless of its position.

All adjustable parts of the attachment and the equipment, such as lifting, Seitenverschiebe- and pivoting devices or the like, depending on the design hydraulically, pneumatically and / or electrically operated. In particular, this can also be dependent on the possibilities of the respective road vehicle, so that advantageously existing systems are utilized.

According to one embodiment, the countersunk lid lifter may comprise a hoist arranged on the appliance holder. This enables a single control of the countersunk lid lifter, ie lifting and lowering only the countersunk lid lifter, without having to move further devices or the entire device holder. The lifting mechanism of the Senkkastendeckelhebers must then take much lower forces when lifting than a hoist that lifts the entire device holder and can therefore be smaller and cheaper.

Preferably, the devices are always arranged in a predetermined, equal distance from each other. Depending on the dimensions of the Senkkastendeckel have introduced into the street drain suction pipe of the mud trap and the Senkkastendeckelheber at a distance that corresponds to at least the width with which a Senkkastendeckel projecting towards the Senkkastendeckelheber laterally projecting in the direction of the mud trap. This ensures that a lowered with the Senkkastendeckelheberer Senkkastendeckel is not held over the opening of the road drain and its entire cross-sectional area is freely accessible. In a preferred embodiment, the distance between the suction pipe of the mud trap, which can be inserted into the street drain, and the Senkkastendeckelheber is at least 130 mm.

The sludge trap cleaner or at least the suction pipe of the sludge trap cleaner can be connected in a further embodiment with a boom above the Senkkastendeckelhebers to the device holder, in which case the distance between the suction pipe and Senkkastendeckelheber is defined by the boom and a constant distance between them is guaranteed. According to a first embodiment of the suction tube with boom is further provided that the suction pipe of the mud trap with the boom in at least a partial area around the Senkkastendeckelheber pivotable about the device holder is held. This can also be parked or otherwise difficult to reach by other obstacles road courses are easily controlled, which would not be achievable with a non-pivoting or laterally projecting suction tube. The suction tube can have a pivoting range which is limited by at least two stops. In particular, the pivoting range is 90 ° in the horizontal, wherein a first end position of the boom is set at an angle of 90 ° to the direction of travel of the road vehicle and a second end position is aligned in the direction of travel, the suction tube is preferably arranged in the second end position in front of the Senkkastendeckelheber , In particular, the pivoting range can also be at least 120 °, in particular at least 150 ° or up to 180 °.

According to an alternative second embodiment can also be provided that the sludge trap with the boom in the direction of travel is arranged in front of or behind the Senkkastendeckelheber, sludge trap and Senkkastendeckelheber are mutually supported in the direction of travel slidably on the device holder.

Instead of devices arranged at a predetermined distance from one another, one of the devices, that is to say the countersunk lid lifter or the sludge trap cleaner, can also be movable relative to the other device in a further alternative embodiment. In particular, the Senkkastendeckelheber be relatively movable to the sludge trap cleaner or at least the suction pipe of the sludge trap, then by moving, pivoting, rotating or tilting the Senkkastendeckelhebers with the Senkkastendeckel the road is released, so that the suction pipe is inserted into this. Suction pipe and Senkkastendeckelheber the device are then in a starting position of the device advantageously over one another, in particular aligned one above the other, arranged in relative to the suction tube movable Senkkastendeckelheber. To a street drain with countersunk lid too clean, then only the countersink lid lifter must be moved and not both devices together. The countersunk lid lifter is then assigned to a sliding, pivoting, rotating or tilting device, which is to be arranged additionally or alternatively to the displacement device of the device holder. Greater flexibility with regard to the operating and control options can be achieved by assigning a sliding, swiveling, rotating or tilting device to both the countersunk lid lifter and the sludge trap cleaner.

In order to introduce the suction pipe in the street drain or its drainage can also be provided that the suction pipe is associated with a lifting mechanism of the sludge trap, with this relative to the Senkkastendeckelheber and / or the device holder movable, that is in a substantially vertical Direction is raised and / or lowered, is. This hoist can be composed of a lifting cylinder, in particular a hydraulic cylinder and a guide rod arranged parallel to the suction pipe, on which at least one guide sleeve formed on the suction pipe is displaceable at a distance from a connection of the lifting cylinder and the suction pipe. The hoist associated with the suction tube advantageously has a stroke of at least 500 mm, in particular at least 600 mm, in particular at least 800 mm.

In addition or as an alternative to the lifting mechanism, the suction pipe can also be made telescopic, with a telescoping part of the suction pipe being insertable into the sludge trap of the road drain. At least the insertable into the street drain, especially telescopic part of the suction pipe can also be designed as a removable end piece, so that it is easily replaceable in case of damage.

In order to clean differently shaped and different sized road courses in an optimal way, the suction tube can be controlled relative to the rest of the device holder, so that the suction tube during cleaning within the street drain back and forth movable or pivotable or reciprocally movable and pivoted. The suction pipe can then be guided within corners of the road to remove all dirt therefrom. The road vehicle or the rest of the device holder must not be moved with appropriate training during cleaning. A corresponding individual control of the suction tube can be combined according to the invention with each embodiment of the device, wherein at a predetermined, fixed distance from each other arranged intake manifold and Senkkastendeckelheber, the distance is to be defined such that this is either on a middle position of the intake manifold or by the einzelsteuerungsbedingte maximum deflection of the suction tube specified minimum distance applies. Even road drains with a below the Senkkastendeckels widening cross section can be completely cleaned in a simple manner. Alternatively or additionally, it can be provided that, according to a further development, at least one lower section of the suction pipe is formed by a flexible hose made of plastic or rubber, which deforms flexibly when pressure acts on it.

In order to ensure safe guidance of the suction tube against twisting during lifting and lowering, the suction tube can be assigned at least one guide roller, along which a guide rail of the suction tube can be guided. This guide rail may consist of a formed on the suction pipe flat profile.

In a further embodiment, the suction pipe is connected to a vacuum generator and a collecting container of the device. Both the collecting container and the vacuum generator can be in one, be arranged in particular in a common structure for the road vehicle. Depending on the road vehicle, a corresponding structure may be designed differently, for example with regard to its mounting options on the road vehicle, dimensions or receiving volume of the collecting container.

Between the suction pipe and the collecting container, a spring-loaded flange connection is advantageously formed, with which a simple emptying of the collecting container is ensured by tilting it, for example, and at the same time creating a secure, sealed connection between the assembly and the suction pipe. The suction tube is pressed with a flange-like end against a likewise flange-shaped connecting arc of the collecting container. Another connection does not exist. For this purpose, the flange-like end of the suction tube in a further embodiment, a spring element associated with which it is received in a holder, so that an accurate alignment of the flange-like end is ensured. Advantageously, the flange-like end of the suction tube or the holder with the spring element is also arranged above a cab of the road vehicle to ensure the shortest possible distance between an inserted into a street drain end of the suction pipe and the sump. In particular, in the case of a collecting container or structure which can be tilted laterally relative to the road vehicle, a latching mechanism can additionally be provided which secures the spring-loaded flange. Also possible is a hydraulically adjustable end of the suction tube, in addition to or supporting the spring element, a cylinder is actuated. The cylinder could then be coupled in a further embodiment with an emptying flap of the collecting container or a cover flap of the structure and its control, so that the flange connection is automatically released when emptying the collecting container.

According to a development, the suction pipe at its open end also be associated with a surrounding this sheath element with which a clean to be cleaned road drain with attached suction pipe to the outside can be sealed. All, applied by means of the vacuum generator suction thus acts on the dirt in the street drain and can be particularly effectively sucked. In order to create with the jacket element the space sealed to the outside, it is provided that the jacket element is movable in the longitudinal direction of the suction pipe relative thereto. The jacket element can thus be lowered down to the street or the surface of the street drain, with an upper seal on or to the suction tube being ensured by means of a plastic sleeve sliding on the suction tube. The relative movement of the jacket member to the suction tube can be achieved by gas spring, with which the jacket element can be pressed in the direction of footprint of the road vehicle. Preferred material for the shell element is at least at its aufzusetzenden on the surface rubber, such as a rubber apron or the like.

Furthermore, the intake manifold may be associated with an air supply line through which air is additionally blown into the roadway to be cleaned during the cleaning of the road drains and which thus causes a better release of adhering dirt. For this purpose, with appropriate design or preparation of the road vehicle and the vacuum generator Koanda system can be exploited, so that at least a portion of the sucked air is circulated. Preferably, the air supply line is combined with the jacket element in order to achieve an even better cleaning performance, so that air can be introduced into the space bounded by the jacket element with the air supply line.

In addition to the suction pipe, the part of the sludge trap cleaner to be introduced into a street drain can also contain at least one rinsing nozzle or spray nozzle, in particular at least two rinsing or spraying nozzles. in particular at least four rinsing or spraying nozzles, have a rinsing device, with the hardened deposits and impurities are first dissolved with high pressure before they are sucked with the suction pipe into the sump. Flushing nozzle and one of these associated flushing line can continue to be integrated into the suction pipe, so that the intake manifold, flushing nozzle and flushing line form a unit. One of the rinsing nozzle associated rinsing agent container with a detergent pump may be integrated together with the collecting container and the vacuum generator in a common structure for the road vehicle, wherein rinsing agent container and rinsing nozzle are connected to each other via the rinsing line.

Both the spray nozzle for detergent and the air supply can be directed at least with a partial flow against an upper edge of the street drain, in particular the seat of the Senkkastendeckels to clean them with high pressure. Further, the suction pipe may also have lateral openings, which are held during the cleaning of the road drains in the amount of the upper edge of the road drain and thus additionally generate a suction effect in this area.

Since when lifting the countersunk lid partly high forces must be expended, especially when they are iced, and to relieve a suspension of the road vehicle at the interface to the cultivation, the device holder may have a support wheel, in particular a height-adjustable support wheel, of which a part is picked up when lifting the countersunk lid on the suspension load. Depending on the system, this jockey wheel can be hydraulically, pneumatically or electrically actuated and controlled, that is to say lowered, if necessary, during the lifting of the countersunk box lid onto a road or footprint. In particular, in a hydraulic or pneumatic system, a constant pressure of the support wheel on the road or surface can be exercised and maintained. Alternatively or In addition to a height adjustment, a suspension of the support wheel can be provided.

In order to relieve the road vehicle not only when raising the countersunk box cover and to reduce the weight of the attachment acting on the suspension at the interface of the road vehicle, this can have its own chassis with at least one support wheel. At least a portion of the weight of the attachment is then supported on the at least one support wheel, so that the weight of the road vehicle is a less limiting factor and the device even with particularly light, small vehicles whose stability would not be guaranteed by the weight of the device used can be. Preferably, this suspension of the device consists of at least two support wheels, which are each arranged at the interface or the suspension opposite front corners of the attachment. An additional support can be achieved in that in addition to the two front support wheels at least one further centrally disposed near the suspension support wheel of the chassis is provided. In a single support wheel of the landing gear, the device is advantageously connected to the road vehicle at at least two spaced-apart points. The attachment with the device is then supported by the chassis always at least three points by the chassis or the road vehicle and the chassis, which may be provided depending on the configuration of the attachment, a chassis with more wheels, for example, if the sump or the detergent container integrated into the cultivation.

In a preferred embodiment, the support wheels of the chassis are each rotatable about a vertical axis, in particular infinitely rotatable, so that the attachment to the chassis follows in a simple manner predetermined by the road vehicle direction of travel. A safe even when road bumps, gradients and the like Attachment with chassis to the road vehicle can be achieved by the suspension is designed floating on the road vehicle. By unevenness of the footprint of road vehicle and cultivation-related movements of these relative to each other are then compensated on the suspension.

Further, the invention relates to a road vehicle for cleaning road courses, comprising a device comprising at least one attachment having a device holder and attached to the device holder devices which are displaceable on the device holder at least transversely to a predetermined direction of travel of the road vehicle and of which at least one is a countersunk lid lifter, wherein at least one of the appliances attached to the appliance holder is a mud-trap cleaner, the mud-trap cleaner having a suction tube carried on the appliance holder, and wherein the countersink lid lifter and the mud trap cleaner form a road drain cleaner. This vehicle is characterized in that the Senkkastendeckelheber is associated with at least one lid pressing device, and that the lid latching device is at least partially below the Senkkastendeckelhebers vorbeiführbar or that the lid latching device is at least in a sub-area below a spanned by the Senkkastendeckelheber, horizontal level is feasible.
