Nachfolgend wird anhand von Figur 3 das Antriebskonzepts der bekannten mobilen Schachtwinde der SIEMAG TECBERG näher erläutert:
Der Windenantrieb (1) der Winde (2) wird von einem Hydraulikmotor (1a) und einem Getriebe (1b) gebildet. Der Antrieb des Hydraulikmotors (1a) erfolgt mit Hydraulikflüssigkeit aus einem Tank (3), die mit einer der beiden Pumpen (4,5) gefördert wird. Die erste Pumpe (4) wird von einem auf der mobilen Schachtwinde angeordneten Dieselmotor angetrieben. Die zweite Pumpe (5) wird von einem auf der mobilen Schachtwinde angeordneten Elektromotor angetrieben. Der wahlweise Betrieb des Hydraulikmotors (1a) über die erste Pumpe (4) oder die zweite Pumpe (5) erfolgt mit einer Hydrauliksteuerung (6). Im Regelbetrieb erfolgt der Antrieb des Hydraulikmotors (1a) mit der Hydraulikpumpe (5), die von dem Elektromotor (5a) angetrieben wird, wobei der Elektromotor (5a) aus dem Stromnetz (7) mit Energie versorgt wird. Auf die Pumpe (4), die von dem Dieselmotor (4a) angetrieben wird, wird bei Stromausfall umgeschaltet oder wenn aus anderen Gründen kein Stromnetz (7) verfügbar ist.The following is based on FIG. 3 The drive concept of the well-known mobile shaft winch of SIEMAG TECBERG is explained in more detail:
The winch drive (1) of the winch (2) is formed by a hydraulic motor (1a) and a gearbox (1b). The drive of the hydraulic motor (1 a) takes place with hydraulic fluid from a tank (3) which is conveyed by one of the two pumps (4, 5).

Die Lösung dieser Aufgabe basiert auf dem Gedanken, dass der Windenantrieb rein elektrisch erfolgt. Im Einzelnen wird die Aufgabe bei einer mobilen Schachtwinde der eingangs erwähnten Art dadurch gelöst, dass

  • der Windenantrieb ausschließlich einen Elektromotor umfasst,
  • die Steuerung für einen wahlweisen Betrieb des Elektromotors an einem Stromnetz oder einem elektrischen Generator eingerichtet ist,
  • ein Verbrennungsmotor den Generator antreibt und
  • der Generator und der Verbrennungsmotor an dem Trägerfahrzeug angeordnet sind und
  • der Verbrennungsmotor des Fahrzeugantriebs über einen Nebenabtrieb den Generator antreibt, wobei der Nebenabtrieb als schaltbare Welle an einem Nebenausgang des Getriebes des Fahrzeugantriebes ausgeführt ist.
The solution to this problem is based on the idea that the winch drive is purely electric. In detail, the problem is solved in a mobile shaft winch of the type mentioned in that
  • the winch drive comprises exclusively an electric motor,
  • the controller is set up for an optional operation of the electric motor on a power grid or an electric generator,
  • an internal combustion engine drives the generator and
  • the generator and the internal combustion engine are arranged on the carrier vehicle and
  • the internal combustion engine of the vehicle drive via a power take-off drives the generator, wherein the power take-off is designed as a switchable shaft at a side exit of the transmission of the vehicle drive.

Die Energie zum Betreiben des Elektromotors wird ohne zusätzliche Hydraulikaggregate über das Stromnetz und im Falle von dessen Ausfall oder Nichtverfügbarkeit über einen Generator bereitgestellt, der von einem Verbrennungsmotor, insbesondere einem Dieselmotor angetrieben wird. Eine weitere Reduzierung des Gewichts und Bauraumes wird daduurch erzielt, dass der Verbrennungsmotor des Fahrzeugantriebs über einen Nebenantrieb den Generator antreibt. Der während des Betriebs der Trommelwinde für den Antrieb des Trägerfahrzeugs nicht benötigte Antriebsmotor übernimmt damit eine Doppelfunktion, sodass die erfindungsgemäße mobile Schachtwinde deutlich einfacher und damit kostengünstiger herstellbar ist. Der Nebenabtrieb ist als schaltbare Welle an einem Nebenausgang des Getriebes des Fahrzeugantriebes ausgeführt, die dem elektrischen Generator die nötige Bewegungsenergie zuführt.The energy for operating the electric motor is provided without additional hydraulic power units via the power grid and in the case of its failure or unavailability via a generator which is driven by an internal combustion engine, in particular a diesel engine. A further reduction in weight and installation space is achieved by the fact that the internal combustion engine of the vehicle drive drives the generator via a power take-off. The drive motor, which is not required for driving the carrier vehicle during operation of the drum winch, thus assumes a double function, so that the mobile shaft winch according to the invention is much simpler and thus less expensive to produce. The power take-off is designed as a switchable shaft at a side exit of the transmission of the vehicle drive, which supplies the necessary kinetic energy to the electric generator.

Ein an der Drehplattform des Trägerfahrzeugs angeordnetes Hydrauliksystem, das für einen Betrieb von Nebenfunktionen der mobilen Schachtwinde eingerichtet ist, kann deutlich kleiner, einfacher und leichter ausgeführt werden, als das Hydrauliksystem im Stand der Technik, das auch den Antrieb der Trommelwinde sicherstellen muss. Ein Hydrauliksystem für den Betrieb von Nebenfunktionen für die mobile Schachtwinde umfasst

  • einen Tank zur Aufnahme von Hydraulikflüssigkeit,
  • eine elektrisch angetriebene Hydraulikpumpe mit einer Saug- und einer Druckseite, wobei die Saugseite in flüssigkeitsleitender Verbindung mit dem Tank und die Druckseite in flüssigkeitsleitender Verbindung mit mindestens einem Aktor für den Betrieb einer Nebenfunktion stehen.
A arranged on the rotating platform of the host vehicle hydraulic system, which is set up for operation of auxiliary functions of the mobile shaft winch, can be made significantly smaller, easier and easier than the hydraulic system in the prior art, which must ensure the drive of the drum winch. A hydraulic system for the operation of auxiliary functions for the mobile shaft winch includes
  • a tank for receiving hydraulic fluid,
  • an electrically driven hydraulic pump with a suction and a pressure side, wherein the suction side in fluid-conducting connection with the tank and the pressure side in fluid-conducting connection with at least one actuator for the operation of a secondary function.

Als Aktoren weist das Hydrauliksystem insbesondere Hydraulikzylinder und/oder Hydraulikmotoren auf. Verfügt die mobile Schachtwinde über einen insbesondere teleskopierbaren Ausleger, wird dessen Winkel zur Drehplattform vorzugsweise mit einem Hydraulikzylinder verändert. Die relative Verdrehung der Drehplattform zu dem Grundrahmen erfolgt beispielsweise mit einem Hydraulikmotor. Die elektrisch angetriebene Hydraulikpumpe zum Betrieb der Aktoren für die Nebenfunktionen ist für einen wahlweisen Betrieb an dem Stromnetz oder, falls dieses nicht zur Verfügung steht, dem elektrischen Generator eingerichtet, der im Bedarfsfall auch die Energie für den Elektromotor des Windenantriebes bereitstellt.As actuators, the hydraulic system in particular hydraulic cylinder and / or hydraulic motors. Has the mobile shaft winch on a particular telescopic boom, whose angle is preferably changed to the rotating platform with a hydraulic cylinder. The relative rotation of the rotary platform to the base frame, for example, with a hydraulic motor. The electrically driven hydraulic pump for operating the actuators for the auxiliary functions is adapted for selective operation on the power grid or, if this is not available, the electric generator, which also provides the energy for the electric motor of the winch drive when needed.

Vorzugsweise ist auf der Drehplattform der mobilen Schachtwinde ein Teleskopausleger mit Führungselementen, insbesondere Führungsrollen für das Förderseil angeordnet, mit dessen Hilfe der an dem Förderseilende angeschlagene Korb in vertikaler Verlängerung des Schachtes ausgerichtet wird. Alternativ oder zusätzlich kann das Förderseil über Führungselemente, insbesondere eine an einem Fördergerüst angeordnete Seilscheibe in den Schacht umgelenkt werden.Preferably, a telescopic boom with guide elements, in particular guide rollers for the hoisting rope is arranged on the rotating platform of the mobile shaft winch, by means of which the battered at the hoist end basket in vertical extension of the shaft is aligned. Alternatively or additionally, the hoisting rope can be deflected into the hoistway via guide elements, in particular a sheave arranged on a conveyor frame.

In die Seele des Förderseils kann ein abgeschirmtes Kabel eingelassen sein, über das eine Signalübertragung zwischen Personen in dem Korb und einer Gegenstelle der mobilen Schachtwinde übertragen werden kann.In the soul of the hoisting rope a shielded cable can be embedded, via which a signal transmission between persons in the basket and a remote location of the mobile shaft winch can be transmitted.

Um den Stand des Trägerfahrzeuges im Betrieb der mobilen Schachtwinde zu verbessern, ist dieses vorzugsweise mit ausfahrbaren, hydraulischen Stützen ausgestattet.In order to improve the state of the carrier vehicle during operation of the mobile shaft winch, this is preferably equipped with extendable, hydraulic supports.

Figur 1 zeigt eine mobile Schachtwinde mit einem LKW als Trägerfahrzeug (11) mit einem Fahrzeugantrieb (12), der von einem Dieselmotor mit angeflanschtem Getriebe gebildet wird. An einem starren Grundrahmen (13) des LKWs ist über eine Drehverbindung (14) eine Drehplattform (15) angeordnet. FIG. 1 shows a mobile shaft winch with a truck as a carrier vehicle (11) with a vehicle drive (12), which is formed by a diesel engine with flanged gear. On a rigid base frame (13) of the truck a rotary platform (15) is arranged via a rotary joint (14).

Auf der Drehplattform (15) befindet sich eine von einem Windenantrieb angetriebene Trommelwinde (16) zum Auf- und Abwickeln eines Förderseils (17). Von der Trommelwinde (16) erstreckt sich ein Teleskopausleger (18), mit dessen Hilfe das Förderseil (17) mit dem an dessen Seilende angeschlagenen, in der Figur nicht dargestellten Korb über der Schachtöffnung ausgerichtet wird. Am Ende des Teleskopauslegers (18) ist zur Umlenkung des Förderseils (17) eine Umlenkrolle (19) drehbar gelagert.On the turntable (15) is a driven by a winch drum winch (16) for winding and unwinding of a hoisting rope (17). From the drum winch (16) extends a telescopic boom (18), by means of which the hoisting rope (17) is aligned with the battered at the end of the rope, not shown in the figure basket above the shaft opening. At the end of the telescopic boom (18) a deflection roller (19) is rotatably mounted for deflecting the conveying cable (17).

Auf der Drehplattform (15) befinden sich ferner die Antriebskomponenten der Trommelwinde (16) sowie für die Nebenfunktionen, die nachfolgend anhand von Figur 2 näher erläutert werden.On the turntable (15) are also the drive components of the drum winch (16) and for the secondary functions, which are described below with reference to FIG. 2 be explained in more detail.

Die Trommelwinde (16) umfasst eine Seiltrommel (21), die mit einem Windenantrieb (22) verbunden ist, der von einem Elektromotor (22a) und einem die Drehzahl des Elektromotors (22a) herabsetzenden Getriebe (22b) gebildet wird. Über eine Steuerung (23) ist der Elektromotor (22a) wahlweise an einem Stromnetz (24) oder einem elektrischen Generator (25) betreibbar. Im Regelbetrieb wird der Elektromotor (22a) an dem Stromnetz (24) betrieben. Ist das Stromnetz (24) nicht verfügbar, übernimmt der Generator (25) die Energieversorgung des Elektromotors (22a).The drum winch (16) comprises a cable drum (21) which is connected to a winch drive (22) which is formed by an electric motor (22a) and a gear (22b) which reduces the speed of the electric motor (22a). Via a controller (23), the electric motor (22a) is selectively operable on a power grid (24) or an electric generator (25). In normal operation, the electric motor (22a) is operated on the power grid (24). If the power grid (24) is not available, the generator (25) takes over the power supply of the electric motor (22a).

Der Elektromotor (22a) des Windenantriebs (22) ist vorzugsweise ein Servomotor. Hierdurch ist eine exakte Kontrolle der Winkelposition der Motorwelle sowie der Drehgeschwindigkeit und Beschleunigung möglich. Die Verwendung eines Servomotors für den Windenantrieb (22) ermöglicht eine deutlich exaktere Steuerung der Trommelwinde und damit Positionierung des an dem Förderseilende befestigten Korbs.The electric motor (22a) of the winch drive (22) is preferably a servomotor. As a result, an exact control of the angular position of the motor shaft and the rotational speed and acceleration is possible. The use of a servomotor for the winch drive (22) allows a much more precise control of the drum winch and thus positioning of the basket attached to the hoist end.

Der Generator (25) wird unter optimaler Ausnutzung der Raumverhältnisse der mobilen Schachtwinde (10) sowie des ohnehin vorhandenen Fahrzeugantriebs (12) über einen Nebenabtrieb (26) des LKW-Dieselmotors (12a) angetrieben. Bei dem Nebenabtrieb (26) handelt es sich um eine zuschaltbare Antriebswelle an einem Nebenausgang des Getriebes des Fahrzeugantriebs (12).The generator (25) is driven by optimal utilization of the space conditions of the mobile shaft winch (10) and the already existing vehicle drive (12) via a power take-off (26) of the truck diesel engine (12a). In the power take-off (26) is a switchable drive shaft at a side exit of the transmission of the vehicle drive (12).

Auf der Drehplattform (15) der mobilen Schachtwinde (10) ist ferner ein Hydrauliksystem (27) angeordnet, das für einen Betrieb der Nebenfunktionen der mobilen Schachtwinde (10) eingerichtet ist. Insbesondere handelt es sich um die Funktionen zum Anheben und Teleskopieren des Teleskopauslegers (18) sowie das Drehen der Drehplattform (15). Als Aktoren für diese Nebenfunktionen kommen Hydraulikmotoren und Hydraulikzylinder zum Einsatz, die von einer Hydraulikpumpe (28) mit einer Hydraulikflüssigkeit aus einem Hydrauliktank (30) beaufschlagt werden. Die Hydraulikpumpe (28) wird von einem Elektromotor (29) angetrieben, der im Regelbetrieb aus dem Stromnetz (24) mit Energie versorgt wird. Bei Nichtverfügbarkeit des Stromnetzes (24) übernimmt der vorhandene Generator (25) die Energieversorgung.On the turntable (15) of the mobile shaft winch (10), a hydraulic system (27) is further arranged, which is adapted for operation of the auxiliary functions of the mobile shaft winch (10). In particular, it is the functions for lifting and telescoping the telescopic boom (18) and the rotation of the rotary platform (15). As actuators for these auxiliary functions are hydraulic motors and hydraulic cylinders are used, which are acted upon by a hydraulic pump (28) with a hydraulic fluid from a hydraulic tank (30). The hydraulic pump (28) is driven by an electric motor (29), which is supplied with power from the power supply (24) during normal operation. If the power grid (24) is unavailable, the existing generator (25) takes over the power supply.

Durch das erfindungsgemäße Antriebskonzept der mobilen Schachtwinde (10) kann das Hydrauliksystem (27) für die Nebenfunktionen deutlich kleiner, einfacher und leichter ausgeführt werden. Der im Stand der Technik erforderliche zusätzliche Dieselmotor als redundanter Antrieb für das Hydrauliksystem entfällt, da der ohnehin vorhandene LKW-Dieselmotor (12a) effektiv über den Nebenabtrieb (26) sowohl für die Erzeugung der Antriebsenergie für den Windenantrieb (22) als auch zum Betrieb der Nebenaggregate genutzt wird.
