Definitions

  • the invention relates to a shaft conveyor system for mining and a method for operating such a shaft conveyor system.
  • Conveyors in underground mining are realized with ropes hanging on ropes.
  • a shaft conveyor system which has a motor associated with a pulley sheave, which leads a conveyor rope for funding.
  • a synchronous linear motor for a vertically oriented travel in an elevator system.
  • a synchronous linear motor is provided with a primary part, which is attached to a passenger transport cabin.
  • the primary part comprises a primary winding, which is designed in the form of tooth coils, and is applied to teeth of the primary part.
  • In the middle of each tooth of the primary part is a permanent magnet.
  • the secondary part has a Rack structure and is made up of individual electrically insulated from each other electrical sheets to keep iron losses in the secondary part as low as possible.
  • the secondary part is also designed completely permanent magnet free. The magnetic fields for generating a feed force are generated solely by the primary part.
  • the invention has for its object to provide a hoistway, in which with regard to a continuous removal over the prior art, an improved material foot is guaranteed.
  • a shaft conveyor system in particular for mining, comprising a plurality, in particular at least three, conveying vessels, which are movable along a shaft, and a linear motor with a arranged on the respective conveying vessel primary part and a longitudinally disposed of the shaft secondary part.
  • the object is achieved by a method for operating such a shaft conveyor.
  • the invention is based on the idea of increasing the number of transport vessels in a shaft conveyor by using a linear motor drive instead of a cable drive. This eliminates the ropes and the equipment in the machine house, which are very maintenance and thus costly. Only by using a linear motor is it possible to operate several delivery vessels at the same time (in the case of a cable drive, it can only be one or at most two).
  • "several" conveying vessels are understood to mean at least three, preferably approximately ten, conveying vessels.
  • the number of delivery vessels is determined individually, where, for example, the topography of the place of use, in particular the depth of the shaft (the deeper, the more vessels can be used), a minimum distance between the individual vessels and / or a loading speed of a loading device for loading the vessels are taken into account. Thanks to the increased number of conveying vessels, the flow of the material to be conveyed is approximately continuous, whereby the throughput per unit of time can be increased slightly and the production process of the production plant, to which the shaft conveyor system belongs, is optimized.
  • the primary part has a movable part of the linear motor and the secondary part has a fixed stator of the linear motor.
  • the movable part corresponds to a rotor and serves to receive the poles of the linear motor, if it is a synchronous linear motor, or to receive the inductor in the case of an asynchronous linear motor.
  • Such a linear motor is significantly cheaper compared to conventional linear motors, in which permanent magnets are arranged in the secondary part.
  • the delivery vessels preferably have a loading volume of not more than 20 t, in particular less than 10 t, in particular of approximately 5 t. They thus have less than 20% of the size of the currently used in a Seil wasteantrieb conveyors. A smaller bucket can be changed easily. In addition, a relatively small and simple loading device is sufficient so that a trouble-free operation of the shaft conveyor system is ensured.
  • the distance depends, among other things, on the depth of the shaft: in the case of a shaft that is more than 1000 m deep, the distance between the individual transport vessels can be quite a few hundred meters.
  • the time interval between two loading operations is always the same, whereby the filling process of the delivery vessels is uniform and is characterized by a high degree of automation.
  • the shaft conveyor system comprises two rails for the conveying vessels, wherein a first rail is provided for a downward movement of the conveying vessels and a second rail is provided for an upward movement of the conveying vessels. Thanks to this construction, an upward movement of the loaded conveying vessels is possible with a simultaneous downward movement of the empty conveying vessels, without the full and the empty vessels having to be transported along a common route and possibly interfering with one another.
  • a deflecting device is provided at each of an upper and a lower end of the rails, which is designed to transport the conveying vessels from one rail to the other rail.
  • the term "upper end” and “lower end” here does not necessarily mean the spatial boundary of the shaft and / or the rails in the vertical direction, but both ends are defined in particular via a discharge and / or a loading level for the conveying vessels. The aim is always to bring the conveying vessels as soon as possible on the other rail, so that the total travel is as short as possible.
  • each bucket on an emergency braking device which is designed in particular as a disc brake which is activated in case of power failure This ensures that in case of failure of the linear motor in the operating state "brakes" goes, for example, if the complete power supply of the delivery system fails ,
  • the linear motor is a synchronous linear motor.
  • the use of a synchronous linear motor has the advantage that compared to an asynchronous motor less energy is needed.
  • FIG. 1 shows a shaft conveyor 2 for mining, which is suitable for use in depths of approximately 200 m to 3000 m.
  • the shaft conveying system 2 comprises a plurality of conveying vessels 4, which are moved down or up along a pair of rails 6a, 6b in a shaft 8.
  • the delivery vessels 4 in this case have a loading volume of about 5 t and two delivery vessels 4 are about 100 m apart.
  • empty conveying vessels 4 are moved down along the rail 6a until they have reached a lower end of the shaft 8.
  • a first deflecting device 10 is mounted, which transports the empty conveying vessels 4 on the second rail 6b.
  • the conveying vessels 4 by means of a loading device not shown in detail with material, especially ore, filled.
  • the loading process is indicated by the arrow 11.
  • the filled conveying vessels 4 are moved upwards over the rail 6b and at an upper end of the shaft 8 they are unloaded via an unloading device (also not shown in more detail), which is symbolized by the arrow 13.
  • a second deflection device 10 finally brings the emptied conveying vessels 4 onto the rail 6a.
  • the transport of the conveying vessels 4 along the shaft 8 is in this case carried out by means of a synchronous linear motor, further referred to as a linear motor 12, the structure of which FIGS. 2 to 4 is explained in more detail so that they can be driven down again and then loaded at the bottom of the shaft 8.
  • a synchronous linear motor further referred to as a linear motor 12
  • FIGS. 2 to 4 the structure of which FIGS. 2 to 4 is explained in more detail so that they can be driven down again and then loaded at the bottom of the shaft 8.
  • the linear motor 12 has a primary part 14 arranged on the respective delivery vessel 4 and a secondary part 16 arranged along the shaft 8.
  • the primary part 14 comprises a movable part, here a pole carrier 18, the permanent magnet, not shown here for generating a magnetic field, which causes a feed force contains.
  • the secondary part 16 is configured permanent magnet-free and has a stator 20.
  • the stator 20 extends substantially over the entire length of the shaft 8.
  • Connected to the stator 20 are two rail elements 22 of the respective rail 6a, 6b.
  • Each bucket 4 is in particular releasably attached to a support structure 24, wherein the support structure 24 is moved over wheels 26 along the rail elements 22.
  • FIG. 4 Further components of the shaft conveyor 2 are shown. In an upper region of the suspension of the bucket 4 sensors 30 are positioned, which are shown symbolically. In addition, each bucket 4 has a braking device 32, which is designed in particular as a disc brake. How out FIG. 4 In addition, it can be seen that a plurality of pole carriers 18 per delivery vessel 4 can be provided, in this case two.
