Definitions
- the invention relates to an Anthebssystem for driving a crusher of a material crushing plant with a main drive and a driven by the main drive transfer case, wherein the transfer case drives at least one generator and a switchably connected to the transfer case first hydraulic pump.
- the invention further relates to a method for operating a crusher of a material crusher with a drive system driving the crusher, wherein the drive system has at least one main drive and one transfer case.
- crushers are used in material crushers as mobile or stationary units for crushing, for example, natural stone or recycled materials, such as concrete, bricks, rubble and the like.
- the material to be shredded to a predetermined size is fed to the crusher.
- This can be designed as an impact crusher.
- an impact crusher the crushed material is detected by a high-speed rotor, accelerated and thrown so long to a fixed impact work until it is crushed to the desired particle size.
- a cone crusher crushing takes place in a circumferentially opening and closing crushing gap between a crushing shell and your crushing cone.
- the crushing cone rotates on an eccentric path.
- jaw crushers in which the shredding of Brechtguts takes place in a wedge-shaped slot between a fixed and a jaw moved by an eccentric shaft.
- crushers Common to such crushers is that they have to apply high forces for crushing the materials. They are designed to be mechanically stable. This leads to large moving masses with correspondingly large moments of inertia.
- the crushers are driven by powerful, high-performance drives, possibly with the interposition of a mechanical transmission.
- a clutch for example a frictional clutch, is provided between the drive and the crusher, through which the torque and power transmission can be interrupted and closed.
- the coupling can also be actuated in the event of a blockage of the crusher.
- the start of the crusher results in a high mechanical and thermal load on the clutch when it is closed and the speed of the crusher is slowly adjusted to the speed of the drive or a transmission output shaft of an intermediate transmission.
- DE 1020151 18398 A1 describes a drive device and a working machine device as well as a method for starting the drive device and the working machine device.
- the work machine can while a crusher, which is driven by a belt drive from the drive means.
- An example designed as a diesel engine main drive is connected via a transmission input shaft to a transmission.
- the transmission is followed by a switchable clutch from which it is connected via a transmission output shaft with the belt drive.
- By actuating the shiftable clutch the torque flow between the transmission input shaft and the transmission output shaft can be interrupted or connected.
- the coupling can be switched for example by means of hydraulic or pneumatic pressure, electromagnetic force, spring force or mechanical actuation.
- the drive device or the working machine device is assigned an auxiliary drive, which is set up to drive the transmission output shaft.
- the drive device or the working machine device can be started with the clutch open, the main drive and ramped up to a predetermined speed.
- the auxiliary drive can accelerate the gear shaft and thus the work machine to a predetermined switch-on speed. Once this is achieved, the clutch is closed and the auxiliary drive is switched off. The work machine is then driven by the main drive.
- To the transmission are connected directly or via respective clutches switchable hydraulic pumps, which are driven by the main drive via the transmission.
- auxiliary drive therefore accelerates the high mass of the working machine before it is coupled to the main drive. As a result, a high load on the clutch when closing the clutch can be avoided.
- main drive mandatory another drive (auxiliary drive) required. This leads to an increased component requirement and thus an increased cost.
- space must be provided for the auxiliary drive within the working machine device, which is not always possible, in particular in the case of space-constrained mobile working machine devices.
- EP 2 500 100 A1 discloses a drive device for a working machine device and the associated working machine device known.
- the drive device comprises at least one drive means, a pump distributor gear, a hydraulic pump, a fluid coupling and a wedge disk.
- the drive means drives the pump distributor gear and above it the hydraulic pump and the wedge disk.
- a clutch and the fluid coupling are interposed between the pump distributor gear and the wedge disk.
- the fluid coupling is connected upstream of the clutch.
- the work machine to be driven can be, for example, a breaker of a construction machine.
- the work machine thus has a high inertia.
- the shiftable clutch serves to interrupt or to connect the torque flow between a transmission input shaft and a transmission output shaft of the pump distributor transmission.
- the object of the invention relating to the drive system is achieved in that a switchable fluid coupling is connected in the transmission path from the transfer case to the crusher, that the switchable fluid coupling and a pump are fluidically connected in a pump circuit and that the switchable fluid coupling by means of the pump, a fluid is supplied.
- a switchable fluid coupling By opening the switchable fluid coupling, the torque and power transmission from the main drive to the crusher can be interrupted. This allows the start of the main drive without power to the crusher.
- By closing the switchable fluid coupling the torque and / or power is directed from the main drive via the transfer case to the crusher.
- the switchable fluid coupling allows a smooth start of the crusher. Extreme load peaks and torsional vibrations are intercepted by the switchable fluid coupling.
- the switchable fluid coupling can be opened quickly. This results in an effective overload protection.
- the switchable fluid coupling thus combines the advantages of a switchable, non-positive coupling and a subsequently arranged, non-switchable fluid coupling, as they are known from the prior art, in one component.
- the torque and / or power transmission of the switchable fluid coupling is adjustable by adjusting the filling amount of the fluid in the switchable fluid coupling.
- the pure switching process for the torque and power transmission can be specified by appropriate adjustment of the level of the fluid in the switchable fluid coupling, which torque is transmitted from the clutch without slippage or with minimal slippage. In this case, a higher level allows the transmission of a larger torque.
- the fluid coupling supplied volume flow of the fluid in a first operating state of the drive system, is greater than the discharged volume flow, that in a second operating state of the drive system, the volume flow of the supplied and the discharged fluid is the same size and that in one third operating state of the fluid coupling supplied volume flow is smaller than the discharged volume flow.
- the inflow or outflow of the fluid into or out of the pump can also be completely interrupted in each case. Is that the fluid coupling supplied volume flow greater than the discharged, so the level rises within the switchable fluid coupling. As a result, a larger torque can be transmitted by the shiftable fluid coupling.
- the torque that can be transmitted by the fluid coupling remains the same. In each case a volume flow of 0 m 3 / min or a deviating from 0 m 3 / min, but the same volume flow can be provided for the incoming and outgoing flow rates. If the discharged volume flow is greater than the volume flow supplied, the transmittable torque can be reduced. In this case, in a complete or at least approximately complete emptying of the switchable fluid coupling, the torque and / or power transmission can be interrupted.
- a simple and reliable interruption of the inflow or outflow of the fluid to and from the formworkable fluid coupling can be achieved in that at least one valve for interrupting the flow is arranged in the pumping circuit of the fluid. If, for example, it is provided that a valve is arranged in the feed line of the switchable fluid coupling, the supply of the fluid to the switchable fluid coupling can be interrupted. With a constant outflow of the fluid from the switchable fluid coupling, the fill level of the fluid within the switchable fluid coupling can be rapidly reduced in this way, and thus the torque or power transmission can be reduced or interrupted.
- the pump is driven by the transfer case or that the pump is driven by the drive shaft of the main drive.
- the pump is thus driven continuously with the main drive regardless of the level of the switchable fluid coupling.
- the level of the switchable fluid coupling can be adjusted in all operating situations in which the main drive is running.
- a powered by the transfer case pump is more accessible, which simplifies installation and maintenance.
- the switchable fluid coupling has bores through which the fluid due to the present within the switchable fluid coupling centrifugal force passed from the switchable fluid coupling and is subsequently passed to the pump.
- rotating main drive and thus rotating switchable fluid coupling fluid is permanently derived in this way from the switchable fluid coupling.
- the level within the switchable fluid coupling can be adjusted by controlling the fluid flow.
- the delivery rate of the pump is greater than the volume flow caused by the centrifugal force through the holes of the switchable fluid coupling. This makes it possible to increase the level of the fluid within the switchable fluid coupling despite permanent outflow of the fluid from the switchable fluid coupling.
- the flow rate of the pump By reducing the flow rate of the pump, the level within the switchable fluid coupling can be reduced.
- the inflow of the fluid to the switchable fluid coupling can be controlled or regulated by a valve which is arranged between the pump and the switchable fluid coupling. The pump can then be operated with constant pumping power. The adjustment of the level takes place by appropriate control or regulation of the switchable fluid coupling supplied volume flow by means of the valve.
- a switching valve with binary switching behavior can be provided, which can be switched between an open and a closed position.
- the level in the switchable fluid coupling and thus its ability to transmit torque and power is increased.
- the level is rapidly reduced according to the outflow of the fluid from the switchable fluid coupling. This allows, for example, a rapid interruption of the torque and / or power transmission in the event of a blockage of the crusher.
- a switching valve can be easily set a minimum and a maximum level in the switchable fluid coupling. It is also conceivable to adjust by a correspondingly timed control of the switching valve intermediate levels and thus a desired torque or power capacity of the switchable fluid coupling.
- a control unit is assigned to the drive system and that the control unit is designed to detect an overload and / or a blockage of the crusher and, in the event of a recognized overload and / or blockage, a control signal indicating a shutdown of the pump and / or an interruption of the fluid supply to the switchable fluid coupling causes output.
- a safe start of the main drive and a smooth start of the crusher can be achieved in that the control unit is adapted to control the pump and / or the valve such that the amount of fluid in the switchable fluid coupling at startup of the speed of the main drive according to its Start and / or increases when starting the speed of the crusher. Due to the increase in the filling quantity, the torque and / or power transmission of the switchable fluid coupling is steadily increased, whereby overloading of the main drive is reliably avoided.
- the complete filling of the previously emptied, switchable fluid coupling preferably takes place in a period of 5 to 60 s, particularly preferably in a period of 10 to 20 s.
- the Ant ebssystem drives the crusher via a belt drive and that a drive pulley of the belt drive is connected to the switchable fluid coupling of the drive system.
- the belt drive can transmit the torque or power over a sufficient distance from the transfer case to the crusher. It allows the setting of a suitable gear ratio, compensates for shock loads and is easy to assemble and maintain.
- other transmission elements between the drive system and the crusher such as a gear transmission, a chain drive, a shaft or the like.
- the drive system is associated with an auxiliary drive, which is in the power transmission direction of the main drive after the switchable fluid coupling directly or indirectly with the crusher in operative connection, then, for example, in the case of a blockade or for maintenance, the crusher in relation to the working direction upside down Be operated direction. It is also conceivable to assist in starting the crusher with the auxiliary drive.
- a simple embodiment of the auxiliary drive can be achieved in that the auxiliary drive is designed as a hydraulic motor and that the hydraulic motor is driven by a driven by the transfer case hydraulic pump.
- the power supply of the auxiliary drive is thus given by the main drive.
- a buffer for the fluid is arranged in the pumping circuit of the fluid, in particular in the return flow of the fluid from the switchable fluid coupling to the pump.
- the fluid in an interruption of the inlet to the switchable fluid coupling, the fluid can drain from the switchable fluid coupling and is collected in the buffer.
- the switchable fluid coupling can be emptied. Accordingly, to fill the switchable fluid coupling fluid can be removed from the buffer and fed to the switchable fluid coupling.
- the object of the invention relating to the method is achieved in that a switchable fluid coupling is arranged between the transfer case and the crusher, that the level of the fluid in the switchable fluid coupling is reduced in the event of a blockage of the crusher and / or for starting the main drive and that Level of the fluid is increased during startup of the crusher.
- a switchable fluid coupling is arranged between the transfer case and the crusher, that the level of the fluid in the switchable fluid coupling is reduced in the event of a blockage of the crusher and / or for starting the main drive and that Level of the fluid is increased during startup of the crusher.
- Figure 1 shows a drive system for a crusher and Figure 2 shows the Anthebssystem shown in Figure 1 with an additional
- FIG 1 shows a drive system 1 for a crusher 50.
- the crusher 50 is used for material crushing, in particular of rock material such as natural stone, concrete, bricks, rubble and the like. He is presently designed as impact crushers. However, it is also conceivable to provide different crushers, such as cone crushers, jaw crushers and the like.
- the crusher 50 and the drive system 1 are present part of a mobile crusher, not shown.
- a main drive 2 is provided to drive the crusher 50.
- the main drive 2 is coupled via a corresponding drive shaft with a first gear 12.1 of the transfer case 10.
- a housing 1 1 of the transfer case 10 further intermeshing gears 12.1, 12.2, 12.3 are arranged.
- a first hydraulic pump 21 and a generator 20 are driven in the present case.
- the first hydraulic pump 21 is connected via a clutch 13 to a second gear 12.2 of the transfer case 10.
- the generator 20 is connected via a connecting element 20.1 with a third gear 12.3 of the transfer case 10.
- the connecting element 20.1 may be a propeller shaft or a coupling.
- a drive pulley 41 of a belt drive 40 is driven.
- a gear ratio of one is predetermined.
- a switchable fluid coupling 30 is interposed in the torque and / or power transmission path from the transfer case 10 to the drive pulley 41.
- the switchable fluid coupling 30 is associated with a pump 31.
- the switchable fluid coupling 30 and the pump 31 are fluidically connected to each other in a pumping circuit.
- Pumping circuit is guided by a fluid.
- a radiator 33 is arranged.
- a buffer 34 for receiving the fluid guided in the pumping circuit is provided in the pumping circuit.
- the switchable fluid coupling 30 is connected via an output shaft 32 to the drive pulley 41.
- the drive pulley 41 drives a driven pulley 43 of the belt drive 40 via a belt drive 42.
- a shaft 51 connects the driven pulley 43 with the crusher 50.
- the main drive 2 is presently designed as a diesel engine. However, other types of engine may be provided, such as an electric motor.
- the switchable fluid coupling works on the Föttinger principle.
- the main drive 2 drives via the transfer case 10 a not shown impeller of the switchable fluid coupling 30 at.
- the impeller delivers a fluid, preferably an oil, to a turbine wheel of the switchable fluid coupling 30 and drives it.
- the turbine wheel is connected to the output shaft 32.
- the output shaft 32 is thus driven by the turbine wheel.
- the rotational movement of the output shaft 32 is transmitted via the drive pulley 41 and the belt drive 42 to the driven pulley 43 of the belt drive 40. This drives the crusher 50 via the shaft 51.
- the amount of fluid stored in the switchable fluid coupling 30 is not constant. It can be adjusted specifically. By changing the level of the fluid in the switchable fluid coupling 30, its ability to torque and / or power transmission can be changed. When fully or almost completely emptied switchable fluid coupling 30 no moment and / or no power is transmitted from her. The crusher 50 is then decoupled from the main drive 2 and the transfer case 10. When the switchable fluid coupling 30 is completely filled, torques and / or powers can be transmitted with an efficiency of greater than 95%. In this case, the switchable fluid coupling 30 has only a slight slip. For a partially filled switchable Fluid coupling 30 is limited in its ability to transmit torque and / or power.
- the pump 31 is presently designed as a gear pump. However, it is also conceivable to use other types of pumps.
- the pump 31 delivers the fluid into the switchable fluid coupling 30. Holes are provided on the outer circumference of the switchable fluid coupling 30. Due to the prevailing centrifugal forces, the fluid flows continuously through the bores from the switchable fluid coupling 30. The switchable fluid coupling 30 is thus continuously emptied when the main drive 2 and thus transfer case 10.
- the pump 31 is designed to pump more fluid into the switchable fluid coupling 30 than to flow out of it through the bores. By switching on the pump 31, a filling of the switchable fluid coupling 30 can thus be achieved. Accordingly, by switching off the pump 31, an emptying operation of the switchable fluid coupling 30 can be initiated.
- the pump 31 is permanently connected to the transfer case 10 and driven by the main drive 2 of this.
- a valve is arranged in the pumping circuit. With the aid of the valve, the fluid flow to the switchable fluid coupling 30 can be interrupted or maintained.
- the valve is presently designed as a solenoid valve. It has two switching position, namely an open and a closed position on. When the valve is open, the switchable fluid coupling 30 is filled and emptied when the valve is closed, due to the outflow of fluid from the bores of the switchable fluid coupling 30.
- the buffer 34 serves to receive the discharged from the switchable fluid coupling 30 fluid. Accordingly, when the valve is open, the fluid taken from the buffer 34 and pumped to the switchable fluid coupling 30.
- the switching valve it is also conceivable to provide a proportional valve in the inlet of the switchable fluid coupling 30 in the pumping circuit. With the aid of the proportional valve, the fluid supply to the switchable fluid coupling 30 can be interrupted. It also makes it possible to continuously predetermine the volume flow of fluid supplied to the switchable fluid coupling 30. Thus, a desired level and thus a desired transmission behavior of the switchable fluid coupling 30 can be adjusted.
- the radiator 33 can be indirectly or directly associated with the fluid coupling in the pumping circuit. This causes the temperature of the fluid remains in a predetermined temperature range and thus does not fall below a predetermined viscosity. The transmission properties of the switchable fluid coupling 30 are thus retained.
- This cooler 33 may be formed in particular as a separate unit. In addition to the fluid coupling 30, other components to be cooled can also be connected to it.
- the switchable fluid coupling 30 without the holes described.
- the fluid can then be sucked out of the switchable fluid coupling 30 by the pump 31.
- valves can be provided both in the inlet and in the outlet of the switchable fluid coupling. It is also possible to adjust the level in the switchable fluid coupling 30 by appropriate control of the pump 31 or the pump 31 and the fluid pump arranged in the return.
- the starting process of the drive system 1 takes place as described below. First, the main drive 2 is started with empty or almost empty switchable fluid coupling 30 and started up to a desired speed. The impeller of the switchable fluid coupling 30 rotates with it.
- the impeller rotates at the same speed as the main drive 2.
- the main drive 2 and the switchable fluid coupling 30 a Provide ratio not equal to 1, so that both rotate at different speeds.
- the pump 31 is driven via the transfer case 10 or directly from the main drive 2.
- the valve disposed between the pump 31 and the inlet of the switchable fluid coupling 30 in the pumping circuit is closed, so that no fluid is pumped into the switchable fluid coupling 30.
- the valve is opened by a corresponding control signal.
- the switchable fluid coupling 30 fills up slowly. This increases the torque transferred from the impeller to the turbine wheel. When the breakaway torque of the output train has been reached, the turbine wheel and the associated output train begin to rotate.
- the drive train comprises all of the output shaft 32 subsequent and moving components. As the level increases, the turbine wheel is slowly accelerated to the speed of the impeller. As a result, the speed of the crusher 50 increases slowly. If the speed of the pump and the turbine wheel turbine wheel equal or at least about the same, by increasing the speed of the main drive 2, the speed of the crusher 50 can be further increased.
- the level in the switchable fluid coupling 30 is reduced.
- the valve provided between the pump 31 and the switchable fluid coupling 30 is closed. Without inflow of fluid, the switchable fluid coupling 30 emptied. Even with partially drained fluid is the moment and Power transmission of the switchable fluid coupling 30 is significantly reduced. As a result, a protection of the blocked crusher 50 is reached shortly after closing the valve. There is a slip between the impeller and the turbine allows, whereby the crusher 50 and the main drive 2 are partially decoupled. A blockage of the crusher 50 thus does not lead to a dying off of the main drive 2 even with partially drained fluid.
- the switchable fluid coupling 30 is designed such that it empties quickly without supplied fluid. As a result, a decoupling of the turbine wheel from the pump takes place in a short time.
- the switchable fluid coupling 30 therefore combines several functions in one component.
- the inertial turbine wheel with the driven train coupled thereto is accelerated to the rotational speed of the drive shaft 32. This causes a soft start of the crusher 50.
- the driving components main drive 2, drive shaft, optionally provided torsional vibration clutches 3, 4 (see Figure 2), transfer case 10, etc.
- the switchable fluid coupling 30 can be interrupted by the switchable fluid coupling 30. This allows the main drive 2 to be started and started up. It also enables a fast decoupling of the main drive 2 from the crusher 50, for example in the event of a blockage or overloading of the crusher 50. Damage to the crusher 50 and the drive system 1 can thus be avoided.
- FIG. 2 shows the drive system 1 shown in FIG. 1 with an additional auxiliary drive 60.
- a second, a third and a fourth hydraulic pump 22, 23, 24 are connected to the transfer case 10.
- the second and the fourth hydraulic pump 22, 24 are coupled directly to the third gear 12.3 of the transfer case 10, while the first and the third hydraulic pump 21, 23 via the Clutch 13 switched on and off the second gear 12.2 of the transfer case 10 are coupled.
- the main drive 2 and the switchable fluid coupling 30 are each attached via a rotary coupling 3, 4 to the housing 1 1 of the transfer case 10.
- the torsional vibration clutches 3, 4 act in the circumferential direction damping and compensate for small offsets in the axis alignment.
- the auxiliary drive 60 is presently designed as a hydraulic motor. It is driven in the embodiment shown by the switchable third hydraulic pump 23. By appropriate operation of the clutch 13, the auxiliary drive 60 can be switched on and off.
- the auxiliary drive 60 acts on the belt drive 42 of the belt drive 40 via a pulley 61.
- the belt drive 40 and thus the crusher 50 connected to the belt drive 40 can thus be moved by means of the auxiliary drive 60.
- the crusher 50 can be rotated, for example, to a suitable maintenance position. It is also possible to rotate the crusher 50 counter to its direction of rotation dictated by the direction of rotation of the main drive 2. In this way, for example, a previous blockage of the crusher 50 can be canceled.
- the auxiliary drive 60 may also be used to assist in starting the crusher 50. For this purpose, the crusher 50 can be accelerated by means of the auxiliary drive 60 before and / or during the filling of the switchable fluid coupling 30 to a predetermined speed.
