Definitions
- the invention relates to a pushed or pulled sweeper mounted on a carrier vehicle, wherein the sweeping tools are electrically driven via a battery motor unit.
- attachments e.g. in the form of attached sweepers, which are pushed or pulled by a carrier vehicle such as a tractor, wheel loader, municipal vehicle or forklift.
- a carrier vehicle such as a tractor, wheel loader, municipal vehicle or forklift.
- the state of the art in these attached sweepers is that they have a sweeping roller oriented transversely to the direction of travel of the machine as a working tool and often also have a disc brush that can be swung out to the side as an additional working tool.
- dust, coarse dirt, waste, etc. lying on the surface to be cleaned are brushed in a direction that corresponds approximately to the direction of travel of the carrier vehicle or, depending on the equipment of the sweeper, conveyed into a collecting container in front.
- the respective working tools, sweeping roller and disc brush are usually each driven by a hydraulic motor.
- the collecting container can be swung from a working position to an emptying position and vice versa using a hydraulic cylinder in the known manner.
- the hydraulic energy is provided by the carrier vehicle through a standardized coupling of the sweeper to the hydraulic system.
- attachments with a hydraulic unit installed on the attachment powered by a combustion engine or electric motor, which provides the necessary hydraulic energy for the working tools.
- the utility model application EN 20 2009 005 011 discloses an attachment with a generator and electrically powered tools such as a sweeper roller.
- the attachment is carried or pushed by a carrier vehicle and is supported by support wheels against the ground during work, with a generator driven by the support wheels and providing energy for the electrical tools.
- Such attachments have not proven themselves in practice, since the The technical implementation, especially the drive of the generator by the support wheels, is very complex and expensive.
- the known carrier vehicles are usually equipped with combustion engines, which, through energy conversion, provide the driving force for the carrier vehicle as well as additional mechanical and hydraulic drive energy for the work tools of the attachments. Due to the combustion engine, these known carrier vehicles generate both harmful noise emissions and exhaust emissions.
- new low-emission or zero-emission carrier vehicles such as tractors, wheel loaders or municipal vehicles have been available on the market.
- These new carrier vehicles are mainly electrically powered and have an integrated energy storage device in the form of batteries.
- These new carrier vehicles also have a hydraulic energy source for operating currently known work equipment, but the energy conversion from electrical energy to hydraulic energy is very inefficient, so that the total running time of the carrier vehicle with hydraulically powered work equipment is extremely short and therefore only partially suitable for practical use.
- the electrically powered carrier vehicles also offer a second, powerful electrical energy source in addition to the standardized 12V electrical energy source.
- the standardized 12V energy source is only designed for low electrical outputs such as driving lights and can only be used to a very limited extent to operate electrical tools in attachments.
- the second new electrical energy source in the carrier vehicle is specially designed for electrical tools in attachments and is intended to replace the hydraulic energy source. This significantly increases the total running time of the carrier vehicle with an electrically operated attachment.
- the invention is based on the object of creating an attachment sweeper with electrical working tools, which can be operated with a wide variety of carrier vehicles and can use a wide variety of electrical energy sources of the carrier vehicle or can also work electrically autonomously.
- the attachment sweeper according to claim 1 has at least one electric drive unit, furthermore a buffer storage for electrical energy and a charging unit for a wide variety of electrical voltages.
- the buffer storage supplies the electric drive unit with energy, so that the drive unit can advantageously also be operated independently.
- the charging unit can be coupled to a wide variety of electrical energy sources from different carrier vehicles and supply the buffer storage with electrical energy, e.g. during work.
- the charging unit can advantageously charge the buffer storage even without a carrier vehicle by connecting it to a public electrical voltage network.
- the drive unit can also be operated without a buffer storage by being supplied with energy directly from the carrier vehicle.
- the drive unit is also advantageously used in hand-held tools, for example. This means that they are produced in large quantities, are easy to obtain and are also inexpensive.
- the output speed can be advantageously adjusted to the required speed of the work tools using gears connected to the drive unit.
- the attachment 1 shown is intended to be pushed along the ground by a motorized carrier vehicle so that dust, coarse dirt, waste, etc. can be swept and collected.
- the attachment 1 consists of a housing 2 which has two rear Fig. 2 visible swivel castors 5 as well as a swivel castor 4 mounted on the front of the collecting container 3.
- the three swivel castors 5 and 4 enable the attachment 1 to move in any direction relative to the ground.
- the 2 rear swivel castors 5 bear the largest part of the mass of the attachment.
- the housing 2 has a number of holes in order to accommodate other components required for operation (e.g.
- roller arms 6 and 7 are fastened to the outer sides of the housing 2 via a rotatable bearing.
- the roller arms 6 and 7 are firmly positioned in the housing 2 via a length-adjustable adjusting means 8, which is articulated on the one hand to the roller arms 6 and 7 and on the other hand to the housing 2.
- the sweeping roller 19 is held at the other end of the roller arms 6 and 7 via a radial bearing 9. Due to operational wear of the sweeping roller 19, the effective diameter of the sweeping roller 19 becomes steadily smaller, therefore an adjustment of the sweeping roller 19 to the processed sweeping surface is necessary.
- the adjustment is carried out by adjusting the adjusting means 8 in the length shortened and the sweeping roller 8 is moved relative to the housing 2 in the direction of the sweeping surface. Further along the side of the housing 2 there are receptacles 10 in which the collecting container 3 is rotatably mounted.
- a joint unit 11 connects the collecting container 3 to the housing 2.
- a length-adjustable adjusting means 12 is also connected to the joint unit 11 and the housing 2.
- the adjusting means 12 is advantageously designed as an electrical adjusting means.
- the collecting container 3 is held in the working position via the joint unit 11.
- the adjusting means 12 has assumed the longest position in the working position shown. By shortening the adjusting means 12, the collecting container 3 is pivoted from the working position into an emptying position.
- a pivotable connecting element 13 is arranged in the front central area of the housing 2.
- An attachment receptacle 14 for a carrier vehicle is attached to the connecting element 13.
- the attachment receptacle 14 can be designed differently depending on the different types of carrier vehicles.
- An electric drive unit 15 is arranged above the housing 2. Below the drive unit 15, an angular gear 16 is connected to the housing 2.
- the output shaft of the drive unit 15 is torsionally connected to a first output shaft of the angular gear 16.
- the second output shaft of the angular gear 16 is torsionally connected to a drive shaft 17.
- the drive shaft 17 runs transversely to the housing 2 through the left roller arm 6.
- the drive shaft 17 is held in the opening of the roller arm 6 via a radial bearing 18.
- a first chain wheel 20 is torsionally connected to the drive shaft 17.
- a further chain wheel 21 is torsionally connected in the left axis of the sweeping roller 19.
- the two chain wheels 20 and 21 are force-locked by means of a chain 22.
- the drive unit 15 thus drives the sweeping roller 19 via the angle gear 16, the drive shaft 17 and the chain drive 48 consisting of 20, 21 and 22.
- the chain drive 48 is only shown here as an example, toothed belt drives or power belt drives or similar can also be used advantageously. Reductions or transmissions can also be realized using different diameters of the chain wheels 20 and 21.
- the angle gear 16 can also be designed as a reduction or transmission gear, so the speed of the working tool to the output speed of the drive unit 15.
- Fig.3 shows the electric drive unit 15 with an integrated electric motor 34 and an integrated energy storage unit 28.
- the integrated energy storage unit 28 supplies the electric drive unit with energy.
- the energy storage unit 28 is advantageously rechargeable and can be replaced without tools. For example, several energy storage units 28 can be carried on the work device 1. If necessary, discharged energy storage units 28 can be replaced with charged energy storage units 28 in the drive unit 15.
- the drive unit 15 is connected via an electrical line 29 to a charger 23 mounted on the work device 1.
- the charger 23 advantageously has several further electrical lines 24 and 25 with corresponding electrical couplings 30 and 31.
- the task of the charger 23 is to supply the energy storage unit 28 integrated in the drive unit 15 with external energy. In a further advantageous embodiment, the charger 23 can also supply the drive unit 15 directly with energy.
- the charger 23 is able to absorb a wide variety of electrical voltages and convert them into the voltage required for the energy storage device 28 or for the drive unit 15.
- the charger 23 can be connected via the electrical coupling 30 either to the electrical energy source of the carrier vehicle or via the electrical coupling 31 to a public electrical supply network. By connecting the charger 23 to a public electrical supply network, the energy storage device 28 can also be charged when the implement 1 is at rest without a carrier vehicle.
- the drive unit 15 is also connected to an operating unit 36 via a further electrical line 35 and is thus supplied with electrical energy.
- the operating unit 36 is in turn connected to the electrical actuating means 12 via a further electrical line 27.
- the operating unit 36 serves, on the one hand, to switch the integrated electric motor 34 in the drive unit 15 on and off and, on the other hand, to control other electrical consumers such as the actuating means 12.
- the operating unit 36 can advantageously be operated from the carrier vehicle.
- Fig. 4 shows a further embodiment of the drive unit 15 in connection with an operating unit 38.
- the drive unit 15 connected to a control unit 37 via the electrical line 35.
- the control unit 37 is in turn connected to the electrical actuating means 12 via a further electrical line 27.
- the operating unit 38 and the control unit 37 are advantageously connected to one another wirelessly (eg via radio).
- the operating unit 38 sends corresponding operating signals to the control unit 37, which in turn switches the integrated electric motor 34 in the drive unit 15 on or off and also controls other electrical consumers such as the actuating means 12.
- Fig.5 shows the electric drive unit 15 with an integrated electric motor 34 and an integrated energy storage unit 28.
- the drive unit 15 is supplied with energy exclusively by the integrated energy storage unit 28.
- the charger 32 shown in this exemplary embodiment is mounted on the work device 1, can accommodate the energy storage unit 28 directly and is not connected to the drive unit 15.
- the task of the charger 32 is to recharge the energy storage unit 28 with external energy. There are therefore two energy storage units 28 in alternating use on the work device 1.
- the first energy storage unit 28 supplies the drive unit 15 with energy and the second energy storage unit 28 is charged by the charger 32 during work.
- the charger 32 is also able to absorb a wide variety of electrical voltages and convert them into the voltage required for the energy storage unit 28.
- the charger 32 can be connected either to the electrical energy source of the carrier vehicle via the electrical coupling 30 or to a public electrical supply network via the electrical coupling 31. By connecting the charger 32 to a public electrical supply network, the energy storage device 28 can also be charged when the implement 1 is at rest without a carrier vehicle. In a further advantageous embodiment, the charger 32 can also be supplied with energy via one or more photovoltaic modules 39 mounted on the implement 1. The photovoltaic module 39 also makes it possible to charge the energy storage device 28 without a carrier vehicle. The charger 32 can also advantageously supply other electrical consumers such as the control unit 37 with electrical energy.
- Fig. 6a and Fig. 6b show an example drive unit 15 consisting of a drive housing 40 in which an electric motor 34 is installed.
- the drive shaft 41 of the electric motor 34 protrudes from the lower drive housing 40.
- the drive unit 15 also has a fastening flange 42 with fastening holes 43 for receiving the drive unit 15.
- the drive housing 40 also has a battery compartment 45 that can be closed with a cover 44.
- the energy storage device 28 is received in the battery compartment 45 via corresponding guides and electrical contacts and is electrically connected to the drive unit 15.
- an electrical connection unit 46 is also provided, which has electrical contacts 47 for e.g. a control unit 37, for a charger 23, 32 or for other electrical consumers.
- Fig.7 shows another exemplary embodiment of the drive unit 15, in which, instead of an energy storage device, an electrical line 33 is connected to the drive unit 15 via electrical contacts (not shown). At the other end of the electrical line 33 is the already known electrical coupling 30, which is connected to the carrier vehicle. The carrier vehicle thus supplies the drive unit 15 directly with energy.
Abstract
Es wird eine geschobene oder gezogene Kehrmaschine (1) zum Anbau an ein selbstfahrendes Trägerfahrzeug bereit gestellt, welches mindestens eine angetriebene rotierende Kehrwalze (19) aufweist, wobei der Antrieb der Kehrwalze (19) durch eine elektrische Antriebseinheit (15) erfolgt die wenigstens einen elektrischen Pufferspeicher (28) aufnehmen kann.A pushed or pulled sweeper (1) is provided for attachment to a self-propelled carrier vehicle, which has at least one driven rotating sweeping roller (19), wherein the sweeping roller (19) is driven by an electric drive unit (15) which can accommodate at least one electric buffer storage (28).
Description
Die Erfindung betrifft eine an einem Trägerfahrzeug angebaute geschobene oder gezogene Kehrmaschine, wobei die Kehrwerkzeuge über eine Batteriemotoreinheit elektrisch angetrieben werden.The invention relates to a pushed or pulled sweeper mounted on a carrier vehicle, wherein the sweeping tools are electrically driven via a battery motor unit.
Es sind handgeführte Kehrmaschinen bekannt, bei der die axial oder radial arbeitenden Kehrwerkzeuge elektrisch angetrieben werden.There are hand-held sweepers in which the axially or radially operating sweeping tools are electrically driven.
Für aufwendigere Arbeiten gibt es Anbaugeräte z.B. in Form von Anbau-Kehrmaschinen, die von einem Trägerfahrzeug wie z.B. Traktoren, Radlader, Kommunalfahrzeuge oder Gabelstapler geschoben bzw. gezogen werden. Bei diesen Anbau-Kehrmaschinen ist es Stand der Technik, dass sie als Arbeitswerkzeug eine quer zur Maschinenlaufrichtung orientierte Kehrwalze tragen und oftmals zusätzlich als weiteres Arbeitswerkzeug einen seitlich ausschwenkbaren Tellerbesen aufweisen. Durch die Drehung der Kehrwalze und des Tellerbesens wird auf der zu reinigenden Fläche liegender Staub, gröberer Schmutz, Abfall etc. in eine annähernd in Fahrtrichtung des Trägerfahrahrzeugs entsprechende Richtung gebürstet oder ggfls. je nach Ausstattung der Kehrmaschine in einen vorlaufenden Sammelbehälter gefördert. Die jeweiligen Arbeitswerkzeuge Kehrwalze und Tellerbesen werden üblicherweise über je einen Hydraulikmotor angetrieben. Der Sammelbehälter kann in bekannter Weise mittels eines Hydraulikzylinders von einer Arbeitsposition in eine Entleerungsposition und umgekehrt geschwenkt werden. Die hydraulische Energie stellt das Trägerfahrzeug durch eine standardisierte Ankopplung der Kehrmaschine an das Hydrauliksystem zur Verfügung. Als weiteres sind Anbaugeräte mit einem auf dem Anbaugerät installierten mit Verbrennung- oder Elektromotor betriebenen Hydraulikaggregat bekannt, welches die notwendige hydraulische Energie für die Arbeitswerkzeuge zur Verfügung stellt.For more complex work, there are attachments, e.g. in the form of attached sweepers, which are pushed or pulled by a carrier vehicle such as a tractor, wheel loader, municipal vehicle or forklift. The state of the art in these attached sweepers is that they have a sweeping roller oriented transversely to the direction of travel of the machine as a working tool and often also have a disc brush that can be swung out to the side as an additional working tool. By rotating the sweeping roller and the disc brush, dust, coarse dirt, waste, etc. lying on the surface to be cleaned are brushed in a direction that corresponds approximately to the direction of travel of the carrier vehicle or, depending on the equipment of the sweeper, conveyed into a collecting container in front. The respective working tools, sweeping roller and disc brush, are usually each driven by a hydraulic motor. The collecting container can be swung from a working position to an emptying position and vice versa using a hydraulic cylinder in the known manner. The hydraulic energy is provided by the carrier vehicle through a standardized coupling of the sweeper to the hydraulic system. Also known are attachments with a hydraulic unit installed on the attachment, powered by a combustion engine or electric motor, which provides the necessary hydraulic energy for the working tools.
Die Gebrauchsmusteranmeldung
Die bekannten Trägerfahrzeuge sind üblicherweise mit Verbrennungsmotoren ausgestattet, die über Energiewandlung zum einen die Antriebskraft für das Trägerfahrzeug sowie weitere mechanische und hydraulische Antriebsenergie für die Arbeitswerkzeuge der Anbaugeräte bereitstellt. Diese bekannten Trägerfahrzeuge erzeugen aufgrund des Verbrennungsmotors sowohl gesundheitsschädliche Lärmemissionen wie auch Abgasemissionen. Daher sind seit geraumer Zeit auch neue emissionsarme bzw. emissionslose Trägerfahrzeuge wie z.B. Traktoren, Radlader oder Kommunalfahrzeuge im Markt verfügbar. Diese neuen Trägerfahrzeuge werden überwiegend elektrisch angetrieben und weisen einen integrierten Energiespeicher in Form von Batterien auf. Diese neuen Trägerfahrzeuge weisen ebenfalls eine hydraulische Energiequelle zum Betrieb von derzeit bekannten Arbeitsgeräten auf, allerdings ist die Energiewandlung von elektrischer Energie in hydraulische Energie sehr ineffizient, sodass die Gesamtlaufzeit des Trägerfahrzeugs mit hydraulisch angetriebenen Arbeitsgeräten äußerst gering und somit nur bedingt praxistauglich ist. Daher bieten einige der elektrisch angetriebenen Trägerfahrzeuge auch neben der standardisierten elektrischen 12V Energiequelle eine zweite leistungsstarke elektrische Energiequelle an. Die standardisierte 12V Energiequelle ist nur für geringe elektrische Leistungen wie z.B. Fahrlicht ausgelegt und kann zum Betrieb von elektrischen Arbeitswerkzeugen in Anbaugeräten nur sehr bedingt genutzt werden. Die zweite neue elektrische Energiequelle im Trägerfahrzeug ist dagegen speziell für elektrische Arbeitswerkzeuge in Anbaugeräten ausgelegt und soll dadurch die hydraulische Energiequelle substituieren. Dadurch wird die Gesamtlaufzeit des Trägerfahrzeugs mit einem elektrisch betriebenen Anbaugerät deutlich erhöht. Allerdings gibt es bei den verschiedenen Trägerfahrzeugen noch keine standardisierte zweite Energiequelle, sodass hier unterschiedliche elektrische Spannungen bereitgestellt werden. Das hat zur Folge, dass die Elektromotoren in den Anbaugeräten auf das jeweilige Trägerfahrzeug abgestimmt werden müssen. Das führt zu dem Nachteil das zum einen die Anbaugeräte nicht mehr in bekannter Form mit verschiedenen Trägerfahrzeugen betrieben werden können und zum anderen die Herstellung der individuellen Anbaugeräte aufwendiger und auch in der Beschaffung der individuellen elektrischen Komponenten teurer ist.The known carrier vehicles are usually equipped with combustion engines, which, through energy conversion, provide the driving force for the carrier vehicle as well as additional mechanical and hydraulic drive energy for the work tools of the attachments. Due to the combustion engine, these known carrier vehicles generate both harmful noise emissions and exhaust emissions. For some time now, new low-emission or zero-emission carrier vehicles such as tractors, wheel loaders or municipal vehicles have been available on the market. These new carrier vehicles are mainly electrically powered and have an integrated energy storage device in the form of batteries. These new carrier vehicles also have a hydraulic energy source for operating currently known work equipment, but the energy conversion from electrical energy to hydraulic energy is very inefficient, so that the total running time of the carrier vehicle with hydraulically powered work equipment is extremely short and therefore only partially suitable for practical use. For this reason, some of the electrically powered carrier vehicles also offer a second, powerful electrical energy source in addition to the standardized 12V electrical energy source. The standardized 12V energy source is only designed for low electrical outputs such as driving lights and can only be used to a very limited extent to operate electrical tools in attachments. The second new electrical energy source in the carrier vehicle, on the other hand, is specially designed for electrical tools in attachments and is intended to replace the hydraulic energy source. This significantly increases the total running time of the carrier vehicle with an electrically operated attachment. However, there is still no standardized second energy source for the various carrier vehicles, so different electrical voltages are provided here. This means that the electric motors in the attachments have to be adapted to the respective carrier vehicle. This leads to the disadvantage that, on the one hand, the attachments can no longer be operated in the known way with different carrier vehicles and, on the other hand, the Manufacturing the individual attachments is more complex and the procurement of the individual electrical components is also more expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Anbau-Kehrmaschine mit elektrischen Arbeitswerkzeugen zu schaffen, die mit unterschiedlichsten Trägerfahrzeugen betrieben und unterschiedlichste elektrische Energiequellen des Trägerfahrzeugs nutzen kann oder auch elektrisch autark arbeiten kann.The invention is based on the object of creating an attachment sweeper with electrical working tools, which can be operated with a wide variety of carrier vehicles and can use a wide variety of electrical energy sources of the carrier vehicle or can also work electrically autonomously.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Anbau-Kehrmaschine gemäß Anspruch 1 über mindestens eine elektrische Antriebseinheit verfügt, weiterhin einen Pufferspeicher für elektrische Energie sowie eine Ladeeinheit für unterschiedlichste elektrische Spannungen aufweist. Der Pufferspeicher versorgt die elektrische Antriebseinheit mit Energie, dadurch kann die Antriebseinheit vorteilhaft auch autark betrieben werden. Die Ladeeinheit kann mit unterschiedlichsten elektrischen Energiequellen verschiedener Trägerfahrzeuge gekoppelt werden und den Pufferspeicher z.B. während der Arbeit mit elektrischer Energie versorgen. Weiterhin kann die Ladeeinheit vorteilhaft durch Anschluss an ein öffentliches elektrische Spannungsnetz den Pufferspeicher auch ohne Trägerfahrzeug beladen. In einer weiteren vorteilhaften Ausführung kann die Antriebseinheit auch ohne Pufferspeicher betrieben werden indem sie direkt über das Trägerfahrzeug mit Energie versorgt wird.This object is achieved according to the invention in that the attachment sweeper according to claim 1 has at least one electric drive unit, furthermore a buffer storage for electrical energy and a charging unit for a wide variety of electrical voltages. The buffer storage supplies the electric drive unit with energy, so that the drive unit can advantageously also be operated independently. The charging unit can be coupled to a wide variety of electrical energy sources from different carrier vehicles and supply the buffer storage with electrical energy, e.g. during work. Furthermore, the charging unit can advantageously charge the buffer storage even without a carrier vehicle by connecting it to a public electrical voltage network. In a further advantageous embodiment, the drive unit can also be operated without a buffer storage by being supplied with energy directly from the carrier vehicle.
Die Antriebseinheit wird weiter vorteilhaft z.B. auch in handgeführten Arbeitsgeräten eingesetzt. Dadurch werden sie in großen Stückzahlen produziert, sind leicht zu beschaffen und zudem preisgünstig. Durch Getriebe die mit der Antriebseinheit verbunden sind, kann die Ausgangsdrehzahl vorteilhaft auf die notwendige Drehzahl der Arbeitswerkzeuge angepasst werden.The drive unit is also advantageously used in hand-held tools, for example. This means that they are produced in large quantities, are easy to obtain and are also inexpensive. The output speed can be advantageously adjusted to the required speed of the work tools using gears connected to the drive unit.
