Definitions
- the invention relates to a downwardly conveying conveyor system, in particular a belt conveyor system, by means of which conveyed material is conveyed from a geodetically higher location to a geodetically lower location.
- Downwardly conveying conveyor systems in which a circulating web-shaped, chain-shaped or circular conveyor for receiving and transporting the material to be conveyed, in order to convey the conveyed material down a slope, have long been known.
- a circulating web-shaped, chain-shaped or circular conveyor for receiving and transporting the material to be conveyed, in order to convey the conveyed material down a slope.
- belt conveyor systems or conveyor belts used in mining underground have long been known.
- the load state of such conveyors changes depending on their loading condition, that is, when the usually belt-shaped or belt-shaped conveyor is loaded with conveyed, so the weight force causes a regenerative operating condition in which the weight of the conveyor together with the load sufficient to the conveyor to circulate.
- the conveyor therefore runs independently, and an additionally introduced by the intended drive acceleration moment is to be regarded as unfavorable, since a correspondingly dimensioned additional braking device must be provided to avoid overspeed of the conveyor, which also decelerate the "introduced by the drive acceleration torque " got to.
- the conveying means is not or substantially not or only partially laden (for example only or predominantly on upwardly conveying sections), the acceleration torque of the motor drive is absolutely necessary for driving the conveying means, otherwise the conveying means will at least not start up or will not continue to operate on their own circulates.
- the blades of the paddle wheels that is the impeller and the
- Turbine wheel such hydrodynamic couplings are generally aligned with each other and are aligned in an axial section through the hydrodynamic coupling perpendicular to the impeller bottom or aligned in the direction of the axis of rotation of the hydrodynamic coupling.
- the maximum transmittable torque is greater than in the second opposite direction of rotation, in which the blades of impeller and turbine are arranged to be retarded.
- This can for example help in a load operation, in which drive power or torque is transmitted from the impeller to the turbine, the maximum transmittable torque and thus the maximum transmittable power compared to a straight bladed hydrodynamic coupling to increase, whereas in overrun, that is In operating conditions in which the turbine wheel rotates faster than the impeller, an undesired deceleration of the turbine wheel is reduced by transmitting rotational power or torque from the turbine wheel to the impeller.
- the hydrodynamic coupling therefore becomes such designed so that the blades in the first-mentioned operating state "load operation" are arranged pusher to each other, whereas they are arranged in the second-mentioned operating state "overrun” fleeing each other.
- the invention has for its object to provide a downwardly conveying conveyor, in which in the above-described regenerative operating condition
- an obliquely bladed hydrodynamic coupling is provided in the drive train between the motor drive and the conveyor, which is loaded with the conveyed.
- the hydrodynamic coupling comprises an impeller and a turbine wheel, which together form a toroidal working space which is filled or filled with a working medium for torque or rotary power transmission.
- a constantly filled with working fluid hydrodynamic coupling into consideration advantageously such, in which there is always a predetermined maximum amount of working fluid in the working space.
- hydrodynamic coupling which in addition to the working space includes an additional storage space for receiving working fluid, so that the degree of filling of the working space can be varied by passing working fluid from the storage room into the working space or from the working space in the storage room.
- hydrodynamic couplings come into consideration with an external working medium circuit for filling and emptying the working space.
- the impeller of the hydrodynamic coupling is in a drive connection (drive connection) with the motor drive, and the turbine wheel of the hydrodynamic coupling is in a drive connection (output connection) with the conveyor.
- the inclination is inventively designed such that in the operating state in which the impeller rotates faster than the turbine wheel, the blades of impeller and turbine are arranged to each other fleeing, whereas in the operating state in which the Turbine wheel rotates faster than the impeller, the blades of impeller and turbine are spit-end to each other.
- the selected, advantageously only slight inclination of the blades for example, in the range of 1 ° - 10 ° relative to the axis of rotation of the hydrodynamic coupling, preferably in the range of 1 ° - 5 ° or 1 ° - 3 °, the acceleration support of the conveyor by the motor drive sufficient to accelerate the empty or largely empty or partially filled conveyor.
- Inclination angle possible, for example, up to 30 °, 35 ° or 40 ° or 45 °.
- the hydrodynamic coupling when the working space of the hydrodynamic coupling can be filled more or less by introducing and discharging working medium is achieved by the skew described that at least with a relatively high filling, in particular full filling of the working space, the torque transmitted from the impeller to the turbine wheel is sufficient to start the conveyor by means of the motor drive.
- the hydrodynamic coupling In the regenerative operating state, on the other hand, the hydrodynamic coupling is extremely stiff and protects the conveying means against overspeeding even with a small filling of the working space.
- downwardly conveying conveyor system is understood to mean not only conveyor systems which always convey downward over their entire conveying path, in particular steadily in the mathematical sense, but also those which have partial sections in which they convey upward.
- the end point of the conveyor system is located at a geodetically lower location than the starting point.
- FIG. 1 shows an example of a coupling characteristic of a hydrodynamic coupling embodied according to the invention in a conveyor system in FIG Comparison to the coupling characteristic of a straight-scooped hydrodynamic coupling in such a conveyor system;
- Figure 2 is a schematic representation of the inclination of the blades of impeller and turbine wheel.
- the asymmetric characteristic of the hydrodynamic coupling in the present invention carried out conveyor and for comparison in a dashed line the left part of a symmetrical clutch characteristic in a straight-shoveled hydrodynamic coupling.
- the characteristic of the inventively provided in the conveyor inclined turbine hydrodynamic coupling is in the range of +100% slip, that is, a state in which the impeller rotates at maximum speed and the turbine is up to -100% slip, that is, a state in which is the impeller and the turbine wheel rotates at maximum speed, shown.
- the horizontal lines M and G indicate the torque to be applied by the motor drive in order to approach the empty conveyor (line M) and the maximum acceleration torque applied in the regenerative operating state (line G) by the conveyor loaded with conveyed material.
- the hatching characterizes the combined maximum acceleration torque, which results from the acceleration torque of the self-propelled, maximally loaded conveyor together with the additional acceleration torque transmitted by the motor drive from the hydrodynamic coupling.
- the maximum acceleration torque at which the conveyor is driven by the weight and by the drive via the hydrodynamic coupling is much larger in a straight-scooped hydrodynamic coupling than in the Inventively provided obliquely bladed hydrodynamic coupling.
- FIG. 2 schematically shows the motor drive 2, which is in a drive connection with the impeller 3.1 of a hydrodynamic coupling.
- the turbine wheel 3.2 is in a drive connection with the conveying means 1, for example a drive wheel of a conveyor belt or conveyor belt.
- the impeller 3.1 and the turbine wheel 3.2 each have a multiplicity of blades 4, which are shown in a developed section in the circumferential direction through the working space of the hydrodynamic coupling in Figure 2. As can be seen, the blades 4 are opposite to a vertical one the impeller bottom 3.3 and the axis of rotation of the
