Definitions

  • the invention relates to continuous conveyors, which are used for the transport of large quantities of bulk material such as sand, stone or ore and for the transport of heavy cargo, for example in mining, over or underground mining or loading and unloading of ships, silos, etc.
  • the bulk or general cargo is charged in a loading station on the transport traction means and transported to a dispensing or transfer station.
  • a typical example of a continuous conveyor is a conveyor belt for the removal of crushed ore.
  • the conveyor belt runs on support rollers which are mounted in an elongated support structure made of steel profiles.
  • the drive station comprises, in addition to one or more drive shafts, at least one electric motor, which is usually designed as an asynchronous motor and runs at a relatively high rotational speed, for example 1500 rpm.
  • the continuous conveyor may also comprise a plurality of drive stations, for example two head stations and one or more intermediate stations, each drive station having one or two electric motors and a corresponding number of drive rollers.
  • Faults during transport are passed as shock loads on the drive roller on the output shaft of the transmission and transmitted from there into the drive motor.
  • the transport traction means can suddenly come to a standstill for a short time. Rotor of the engine, shafts and gears of the transmission and the coupled drive roller but move because of the large inertia of the entire drive system on, at least until an automatic shutdown or decoupling of the engine takes place when certain forces are exceeded. This can lead to strong mechanical stresses in the gearbox, engine and transport traction means, as a result of which the traction means is damaged, e.g. tears.
  • an overload clutch is often installed in the prior art between the drive roller and the reduction gear which automatically opens when predetermined loads are exceeded above the normal operating loads, thus separating the electric drive from the drive roller.
  • the invention is based on the finding that the large mass inertia of conventional drive systems is responsible for the fact that the transport traction means is rapidly mechanically overloaded in the event of a malfunction, and that therefore the reduction of the mass inertia of the drive system must be a developmental goal.
  • the object is achieved according to the characterizing part of the first claim, characterized in that instead of a high-speed electric motor with flanged multistage reduction gear, a permanently excited high-pole synchronous motor is used, whose speed is at most 15 times as high as the working speed of the drive shaft he delivers a torque of at least 30 kNm.
  • a slow-running electric motor with high torque makes a complex multi-stage reduction gear superfluous.
  • the acting on the drive roller mass moment of inertia of the drive is thereby reduced to less than 20% of the moment of inertia of a conventional drive.
  • the kinetic energy of the drive system is considerably smaller due to the much lower engine speed. In the event of a malfunction during the transport of bulk or piece goods, the relatively light drive unit reacts faster.
  • the driving force of the motor can be reduced or turned off before unacceptably high forces are introduced via the drive roller in the traction means.
  • the occurring impact torque is significantly lower, whereby the load on the mechanical components is significantly reduced.
  • a deformation or even a crack of the transport traction means is thus practically impossible, an overload clutch unnecessary.
  • the electric motor can drive the drive roller of the transport traction device directly.
  • the engine speed corresponds to the working speed of the drive shaft.
  • a reduction gear is thus completely unnecessary, the mass moment of inertia of the drive is reduced to a minimum.
  • the mass moment of inertia can be reduced by a factor of 10 compared to a conventional drive with a high-speed asynchronous motor and an intermediate reduction gearbox.
  • the efficiency of a drive system with torque motor is about 5% greater. This means lower energy consumption and lower cooling capacity. Rotor cooling is not required for torque motors.
  • the synchronous motors with a large number of pole pairs used here are, in principle, large hollow shaft servomotors optimized for high torques.
  • Rotary direct drives or torque motors have hitherto been used primarily in production machines, such as Laser cutting machines, milling and grinding machines or extruders used, but not in heavy carriers.
  • the rated speed of the synchronous motor is preferably between 5 and 100 revolutions per minute, in particular between 20 U / min and 50 U / min, when the motor drives the drive shaft directly.
  • the output torque is preferably between 50 and 800 kilonewtons, in particular 100 kNm to 500 kNm.
  • Such slow-running synchronous motors with such high torque allow only the direct drive of the transport traction means.
  • the power output of the drive is preferably between 50 and 2000 kilowatts, in particular 100 kW to 1000 kW.
  • the preferred rated speed is higher by a factor of 2 to 10, depending on the reduction ratio, and the torque output by the motor is preferably about half lower. Even in this case, a significant reduction of the moment of inertia results by at least a factor of 5 in comparison to conventional drives.
  • the drive with synchronous motor and single-stage reduction gear has significantly fewer moving parts compared to conventional gearboxes. This means higher system reliability.
  • High-pole synchronous motors or rotary direct drives can be controlled quickly and precisely by means of a frequency converter. Thanks to the use of variable-speed drives, considerable system advantages can be achieved compared to conventional solutions without speed control. Due to the speed and torque control, the conveying process can be fundamentally optimized. This includes monitoring and limiting the speed and torque of the synchronous motor as well as the performance data of the synchronous motor
  • the load can be fixed and thus a smooth and gentle operation of the ascending conveyor can be achieved.
  • the number of pole pairs is preferably between 6 and 50, in particular around 10.
  • FIG. 1 shows a conveyor belt for heavy bulk material, schematically, in an i o horizontal section

  • Whose endless conveyor belt 1 runs between a drive roller 2 and a guide roller 3 in a circle.
  • a heavy bulk material 4 such as ore or broken rock, abandoned and transported substantially horizontally, in the figure from left to right.
  • Support rollers 5 are arranged, which support the weight of the conveyor belt 1 and the bulk material 4.
  • the conveyor belt is driven by a low-speed, high-poled synchronous motor 6 with high torque.
  • the synchronous motor 6 drives the drive roller 2 of the conveyor belt directly, i. without intermediate mechanical gearbox, on.
  • the working speed of the drive roller 2 is about 40 revolutions per minute, so that the synchronous motor 6 has a rated speed of 40 U / min.
  • the synchronous motor 6 outputs a torque in the region of 300 kilonewtons.
  • a second synchronous motor of the same type can be coupled to the drive roller 2. If for reasons of space, the length of the synchronous motor 6 is limited, and a single-stage 15 reduction gear between the drive roller 2 and synchronous motor 6 may be provided, which reduces the speed of the synchronous motor 6, for example by a factor of 5.
  • the synchronous motor 6 is about 20 times as long as it is wide.
  • the segmented design modular synchronous motor 6 has a housing jacket 7, which extends between two end-side end plates 8a and 8b.
  • the bearing plates 8a, 8b are the bearings 9a, 9b for the rotor shaft 10, on which the rotor 1 1 sits.

  • 20 tems is about 10 times smaller than with conventional drives.
  • the spring and damping characteristics of the powertrain are also significantly better.
  • the drive system which in principle comprises only the synchronous motor 6 and the drive roller 2, is capable of torsional vibration due to the mechanical elasticities 25 both in the axial and in the radial direction.
  • the spring stiffness F M of the elasticities on the motor side comprises the torsional stiffness of the motor shaft of the synchronous motor 6 and the axial spring rigidity.
  • the friction damping in the bearings and the damping in the air gap by magnetic reversal are characterized by the damping D m . at
  • the drive system for the conveyor belt 1 shown in Fig. 6 differs from the drive of FIG. 5 only by the interposition of a single-stage reduction gear 15 between the synchronous motor 6 and drive roller 2 of the conveyor belt 1.
  • the synchronous 5 motor 6 no longer necessarily run at the same speed as the drive roller 2.
  • the io reduction gear 15 can be executed.
  • the additional mass moment of inertia M g for the reduction gear 15 increases the total inertia of the drive by two to three times, which is still five to ten times smaller than in conventional drives.

Abstract

L'invention concerne un convoyeur continu, comme, par exemple, une bande transporteuse, pour le transport de produits lourds, en vrac ou en colis. Ce convoyeur comprend une bande transporteuse (1) sans fin qui circule entre un rouleau d'entraînement (2) et un rouleau de renvoi (3). Le rouleau d'entraînement (2) est entraîné par un moteur synchrone (6), multipolaire, à excitation permanente, qui, à une vitesse nominale de rotation relativement faible, fournit un couple très élevé. Le moteur synchrone (6) peut entraîner directement le rouleau d'entraînement (2) ou encore via une transmission de réduction (15) à un seul rapport, offrant un rapport de transmission relativement faible. L'entraînement selon l'invention se caractérise par un moment d'inertie de masse réduit jusqu'à 10 fois par rapport aux systèmes d'entraînement courants. De ce fait, on réduit le risque de détérioration ou même de déchirure de la bande transporteuse (1) en cas de perturbations, de telle sorte que la sécurité de fonctionnement est considérablement améliorée.
