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 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.

Abstract
Die Erfindung betrifft eine Schachtförderanlage (2) für den Bergbau. Im Hinblick auf einen kontinuierlichen Abtransport mit einem verbesserten Materialfuß umfasst die Schachtförderanlage (2) mehrere, insbesondere mindestens drei, Fördergefäße (4), die längs eines Schachts (8) bewegbar sind, und einen Linearmotor (12) mit einem an dem jeweiligen Fördergefäß (4) angeordneten Primärteil (14) und einem längs des Schachts (8) angeordneten Sekundärteil (16).The invention relates to a shaft conveyor system (2) for mining.

Description
Die Erfindung betrifft eine Schachtförderanlage für den Bergbau sowie ein Verfahren zum Betrieb einer solchen Schachtförderanlage.The invention relates to a shaft conveyor system for mining and a method for operating such a shaft conveyor system.
Fördermaschinen im Untertagebergbau werden mit an Seilen hängenden Fördergefäßen realisiert. In
Es werden mit solchen Fördermaschinen, die Teil einer Schachtförderanlage sind, Fördertiefen von ca. 200 m bis 3000 m überwunden. Die wesentlichen Nachteile dabei sind, dass die Förderseile relativ teuer sind, zudem müssen sie in kurzen Abständen geprüft werden und alle eineinhalb bis zwei Jahre getauscht werden. Darüber hinaus weist eine solche Schachtförderanlage zwei Fördergefäße auf, die abwechselnd auf und ab gefahren werden, so dass ein diskontinuierlicher Materialfluss vorliegt. Die Fördergefäße sind groß ausgeführt, typischerweise mit einem Beladevolumen von 30 t bis 50 t. Sie verschleißen schnell, so dass sie im Durchschnitt jedes Jahr ausgetauscht werden müssen. Zudem sind bei Schächten mit einer Tiefe von 1500 m oder tiefer die Seilmassen so groß, dass die Fördermenge dadurch eingeschränkt wird.It will be overcome with such carriers that are part of a shaft conveyor, conveying depths of about 200 m to 3000 m. The main disadvantages are that the hoisting ropes are relatively expensive, they also have to be tested at short intervals and replaced every one and a half to two years. In addition, such a shaft conveyor system has two delivery vessels, which are alternately moved up and down, so that there is a discontinuous material flow. The delivery vessels are large, typically with a loading volume of 30 t to 50 t. They wear out quickly, so they need to be replaced on average every year. In addition, in shafts with a depth of 1500 m or lower, the rope masses are so large that the flow rate is thereby restricted.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Schachtförderanlage anzubieten, bei der im Hinblick auf einen kontinuierlichen Abtransport gegenüber dem Stand der Technik einen verbesserten Materialfuß gewährleistet ist.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.
Die Aufgabe wird erfindungsgemäß gelöst durch eine Schachtförderanlage, insbesondere für den Bergbau, umfassend mehrere, insbesondere mindestens drei, Fördergefäße, die längs eines Schachts bewegbar sind, und einen Linearmotor mit einem an dem jeweiligen Fördergefäß angeordneten Primärteil und einem längs des Schachts angeordneten Sekundärteil.The object is achieved by 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.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren zum Betrieb einer solchen Schachtförderanlage gelöst.The object is achieved by a method for operating such a shaft conveyor.
Die in Bezug auf die Schachtförderanlage nachstehend angeführten Vorteile und bevorzugten Ausführungen lassen sich sinngemäß auf das Betriebsverfahren übertragen.The advantages and preferred embodiments set out below with regard to the shaft conveying system can be transferred analogously to the operating method.
Die Erfindung basiert auf der Überlegung die Anzahl der Fördergefäße in einer Schachtförderanlage zu erhöhen, indem ein Linearmotorantrieb anstelle eines Seilantriebs eingesetzt wird. Dabei entfallen die Förderseile und die Ausrüstung im Maschinenhaus, welche sehr wartungs- und somit auch kostenintensiv sind. Erst durch den Einsatz eines Linearmotors wird ermöglicht, dass mehrere Fördergefäße gleichzeitig betrieben werden (bei einem Seilantrieb können es nur eins oder maximal zwei sein). Unter "mehreren" Fördergefäßen werden hierbei mindestens drei, bevorzugt ca. 10 Fördergefäße verstanden. Die Anzahl der Fördergefäße wird dabei individuell bestimmt, wobei z.B. die Topographie des Einsatzortes, insbesondere die Tiefe des Schachtes (je tiefer, je mehr Gefäße können eingesetzt werden), ein Mindestabstand zwischen den einzelnen Fördergefäßen und/oder eine Beladegeschwindigkeit einer Beladeeinrichtung zum Beladen der Fördergefäße berücksichtigt werden. Dank der erhöhten Anzahl an Fördergefäßen ist der Fluss des Fördergutes annähernd kontinuierlich, wodurch sich der Durchsatz pro Zeiteinheit leicht erhöhen lässt und der Produktionsprozess der Produktionsanlage, zu der die Schachtförderanlage gehört, optimiert wird.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). In this context, "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.
Gemäß einer bevorzugten Ausgestaltung weist das Primärteil einen beweglichen Teil des Linearmotors auf und das Sekundärteil weist einen feststehenden Stator des Linearmotors auf. Der bewegliche Teil entspricht bei einem Linearmotor einem Rotor und dient zur Aufnahme der Pole des Linearmotors, wenn es sich um einen Synchronlinearmotor handelt, oder zur Aufnahme des Induktors bei einem Asynchronlinearmotor. Ein derartiger Linearmotor ist im Vergleich zu üblichen Linearmotoren, bei denen Permanentmagnete im Sekundärteil angeordnet sind, deutlich kostengünstiger.According to a preferred embodiment, the primary part has a movable part of the linear motor and the secondary part has a fixed stator of the linear motor. In the case of a 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.
Vorzugsweise weisen die Fördergefäße ein Beladevolumen von maximal 20 t, insbesondere weniger als 10 t, insbesondere von circa 5 t auf. Sie weisen somit weniger als 20% der Größe der bei einem Seilförderantrieb derzeit eingesetzten Fördergefäße auf. Ein kleineres Fördergefäß kann einfach getauscht werden. Zudem ist eine relativ kleine und einfache Beladeeinrichtung ausreichend, damit ein störungsfreier Betrieb der Schachtförderanlage gewährleistet ist.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 Seilförderantrieb 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.
Im Hinblick auf einen besonders sicheren Betrieb der Schachtförderanlage ist zwischen den Fördergefäßen ein Abstand von einigen zig bis einigen hundert Metern, insbesondere zwischen 50 m und 150 m, insbesondere von ca. 100 m, vorgesehen. Der Abstand ist u.a. von der Tiefe des Schachts abhängig: bei einem über 1000 m tiefen Schacht kann der Abstand zwischen den einzelnen Fördergefäßen durchaus einige hundert Meter betragen. Insbesondere ist der zeitliche Abstand zwischen zwei Beladevorgängen stets der gleiche, wodurch der Befüllvorgang der Fördergefäße einheitlich ist und sich durch einen hohen Automatisierungsgrad auszeichnet.With regard to a particularly safe operation of the shaft conveyor system, a distance of a few tens to a few hundred meters, in particular between 50 m and 150 m, in particular of approximately 100 m, is provided between the conveying vessels. 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. In particular, 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.
Nach einer bevorzugten Ausgestaltung umfasst die Schachtförderanlage zwei Schienen für die Fördergefäße, wobei eine erste Schiene für eine Abwärtsbewegung der Fördergefäße vorgesehen ist und eine zweite Schiene für eine Aufwärtsbewegung der Fördergefäße vorgesehen ist. Dank dieser Konstruktion ist eine Aufwärtsbewegung der beladenen Fördergefäße bei einer gleichzeitigen Abwärtsbewegung der leeren Fördergefäße möglich, ohne dass die vollen und die leeren Gefäße entlang einer gemeinsamen Strecke transportiert werden müssen und sich dabei unter Umständen gegenseitig stören.According to a preferred embodiment, 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.
Nach einer bevorzugten Ausgestaltung ist an einem oberen und einem unteren Ende der Schienen jeweils eine Umlenkvorrichtung vorgesehen, welche dafür ausgebildet ist, die Fördergefäße von der einen Schiene auf die andere Schiene zu transportieren. Unter "oberem Ende" und "unterem Ende" wird hierbei nicht zwingend die räumliche Begrenzung des Schachts und/oder der Schienen in Vertikalrichtung verstanden, sondern beide Enden sind insbesondere über eine Entlade- und/oder eine Beladeebene für die Fördergefäße definiert. Ziel dabei ist stets, die Fördergefäße so bald wie möglich auf die jeweils andere Schiene zu bringen, damit der Verfahrweg insgesamt möglichst kurz ist.According to a preferred embodiment, 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.
Nach einer weiteren bevorzugten Ausgestaltung weist jedes Fördergefäß eine Notbremseinrichtung auf, die insbesondere als Scheibenbremse ausgeführt ist, die bei einem Stromausfall aktiviert wird Dadurch ist sichergestellt, dass im Störfall der Linearmotor in den Betriebszustand "Bremsen" geht, wenn beispielsweise die komplette Stromversorgung des Beförderungssystems ausfällt.According to a further preferred embodiment, 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 ,
Zweckdienlicherweise ist der Linearmotor ein Synchronlinearmotor. Die Anwendung eines Synchronlinearmotors hat den Vorteil, dass gegenüber einem Asynchronmotor weniger Energie benötigt wird.Conveniently, 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.
