Abstract

The invention relates to a waste downpipe for underground mining, which makes it unnecessary to disassemble parts of the preassembled waste downpipes (1, 2) during production of the spiral chute for washing wastes, in order to couple the floor plates (7, 8) to one another by means of a screw connection. According to the invention, a way is shown of erecting the waste downpipes (1, 2), which have been fully preassembled at the works so as to be ready for installation, as quickly as possible, without disassembly and in situ (Fig. 1). <IMAGE>

Description

Einige Vorteile Bei Ausgestaltung gemäß Patentanspruch 1 können die Bergefallrohre fabrikseitig mit Schleißeinlagen und Bodenblechen - wie auch schon bisher - fertigmon- tiert (vormontiert) werden. Im Gegensatz zum Stand der Technik brauchen aber Untertage die Bergefallrohre nicht wieder teilweise demontiert zu werden, um die Bodenbleche miteinander zu verbinden. Vielmehr können die Bergefallrohre in ihrer fabrikseitig vormontierten Art verbleiben, da durch den Längsschlitz in dem einen Bodenblech sich die an dem anderen Bodenblech dauerhaft befestigte, aber lösbare, Schraube in Montagestellung bringen läßt, ohne daß die hier vorgesehenen Schleißplatten vorher abgenommen, also demontiert zu werden brauchen. Nach dem Zusammenfügen zweier benachbarter Bergefallrohre wird die Schraube angezogen, was innerhalb kürzester Zeit möglich ist. Die mühsamen Arbeiten, die bisher mit der Montage und Demontage von Schleißplatten unter schwierigen und gefährlichen Arbeitsbedingungen notwendig waren, entfallen nunmehr vollkommen. Die Montage der Bergefallrohre zu der Wendel geschieht in kürzester Zeit, so daß die Wendel auch nach kürzerer Gesamtmontagezeit in Betrieb gehen kann. Some advantages in the embodiment according to claim 1 can Rescue downpipes from the factory with wear inserts and base plates - as before so far - finished be installed (pre-assembled). In contrast to the However, state-of-the-art technology does not partially need the recovery downpipes again underground to be dismantled in order to connect the floor panels together. Rather, can the recovery downpipes remain in their factory pre-assembled type, as through the longitudinal slot in one floor panel is permanently attached to the other floor panel attached, but detachable, screw can be brought into the assembly position without the Wear plates provided here have been removed beforehand, so need to be dismantled. After joining two adjacent recovery downpipes, the screw is tightened, what is possible within a very short time. The arduous work so far with the assembly and disassembly of wear plates under difficult and dangerous Working conditions that were necessary are now completely eliminated. The assembly of the Rescue downpipes to the helix happens in a very short time, so that the helix too can go into operation after a shorter total assembly time.

Weitere Ausführungsformen In Patentanspruch 2 ist eine besonders vorteilhafte konstruktive Lösung der Erfindung beschrieben. Further Embodiments In claim 2, one is special advantageous structural solution of the invention described.

In der Zeichnung ist die Erfindung - teils schematisch - an einem Ausführungsbeispiel veranschaulicht. In the drawing, the invention is - partly schematically - on one Embodiment illustrated.

Es zeigt F i g. 1 eine Wendelrutsche für Waschberge im Längsschnitt, wobei zwei Bergefallrohre auseinandergezogen dargestellt sind, F i g. 2 einen Schnitt nach der Linie ll-ll der F i g. 1 und Fig. 3 eine Draufsicht zu Fig. 1.It shows F i g. 1 a spiral chute for washing mountains in a longitudinal section, two salvage downpipes are shown pulled apart, FIG. 2 a section according to the line II-II of FIG. 1 and 3 show a plan view of FIG. 1.

Mit dem Bezugszeichen 1 bzw. 2 sind zwei Bergefallrohre bezeichnet, die an ihren Enden jeweils Flansche 4 bzw. 5 aufweisen, die über ihren Umfang mit Abstand zueinander angeordnete Bohrungen versehen sind, durch welche nicht dargestellte Schrauben hindurchgesteckt werden können, so daß die Bergefallrohre 1 und 2 über ihre Flansche 4 und 5 dicht miteinander zu verbinden sind. Normalerweise besteht eine Wendelrutsche für Waschberge aus zahlreichen solcher Bergefallrohre 1, 2, die koaxial zueinander angeordnet sind und z. B. With the reference number 1 or 2, two recovery downpipes are designated, each having flanges 4 and 5 at their ends, which over their circumference with Spaced bores are provided through which not shown Screws can be pushed through so that the recovery downpipes 1 and 2 over their flanges 4 and 5 are to be connected tightly to one another. Usually consists a spiral chute for washing mountains from numerous such mountain downpipes 1, 2, the are arranged coaxially to each other and z. B.

einen mehrere hundert Meter langen Seigerförderer bilden, in dem die Waschberge abwärts gefördert werden können.form a Seiger conveyor several hundred meters long in which the Wash mountains can be promoted downwards.

In jedem Bergefallrohr 1, 2 ist eine schraubenlinig verlaufende Wendel angeordnet, die bei dem Bergefallrohr 1 insgesamt mit dem Bezugszeichen 6 bezeichnet ist. Die Wendel 6 besteht im wesentlichen aus Bodenblechen 7 und 8, die ebenfalls schraubenlinig verlaufend an der Innenmantelfläche 9 bzw. 10 der Bergefallrohre 1 und 2, z. B. durch Schrauben, befestigt sind. Auf den Bodenblechen 7 und 8 sind Schleißplatten 12 bzw. 13 angeordnet, die z. B. aus Hartguß oder einem anderen verschleißarmen Werkstoff bestehen können. In each recovery downpipe 1, 2 there is a helix running in a helical manner arranged, which is designated as a whole with the reference numeral 6 in the case of the recovery downpipe 1 is. The helix 6 consists essentially of floor panels 7 and 8, which are also running helically on the inner jacket surface 9 or 10 of the salvage downpipes 1 and 2, e.g. B. are fastened by screws. On the floor panels 7 and 8 are Wear plates 12 and 13 arranged, the z. B. made of chilled cast iron or another low-wear Material can exist.

Wie aus F i g. 1 hervorgeht, wird ein jedes Bergefallrohr 1,2 fabrikseitig mit der Wendel 6 vormontiert, also mit den in ihm angeordneten Bodenblechen 7 bzw. 8 und den darauf befindlichen Schleißplatten 12 und 13. An den Mündungsöffnungen 14, 15 bzw. 16, 17 ragt die betreffende Wendel 6 mit einem gewissen Längenabschnitt aus dem Bergefallrohr 1 bzw. 2 heraus. As shown in FIG. 1, each recovery downpipe 1,2 is factory-made preassembled with the helix 6, i.e. with the base plates 7 or 8 and the wear plates 12 and 13 located thereon. At the mouth openings 14, 15 or 16, 17, the relevant helix 6 protrudes with a certain length section out of the recovery pipe 1 or 2.

An einem Ende ist das Bodenblech 7 ans einer dem benachbarten Bergefallrohr 1 zugekehrten Stirnseite 18 mit einem Längsschlitz 19 versehen, während das gegenüberliegende Bodenblech 8 im Abstand von der der Stirnseite 18 gegenüberliegenden Stirnseite 20 mit einer Bohrung 21 versehen ist, die in einer in Richtung auf die Innenmantelfläche 10 hingerichteten Einsenkung 22 angeordnet ist (F i g. 2). In diesem Bereich liegt eine Befestigungsschraube 23 mit ihrem Senkkopf 24 bündig mit der der hier vorzusehenden Schleißplatte 12 ztigckehrten Oberfläche 25, so daß die Oberfläche 25 und die Außenfläche 26 des Senkkopfes 24 in Flucht liegen. At one end, the bottom plate 7 is attached to the adjacent recovery downpipe 1 facing end face 18 provided with a longitudinal slot 19, while the opposite Floor plate 8 at a distance from the end face opposite the end face 18 20 is provided with a bore 21, which in a direction towards the inner circumferential surface 10 executed depression 22 is arranged (Fig. 2). In this area lies a fastening screw 23 with its countersunk head 24 flush with the one to be provided here Wear plate 12 ztigckertzen surface 25, so that the surface 25 and the outer surface 26 of the countersunk head 24 are in alignment.

Aus F i g. 2 geht ferner hervor, daß der Abschnitt 27, der den Längsschlitz 19 des Bodenbleches 7 trägt, ebenfalls in Richtung auf die Innenmantelfläche 9 abgekröpft ist, also zur gleichen Seite wie die Einsenkung 22 verläuft. Auf diese Weise wird es möglich, beim Aneinanderflanschen der Bergefallrohre 1 und 2 die Bodenbleche 7 und 8 in Richtung Xzusammenzuschieben, derart, daß der Längsschlitz 19 zwischen der Schraubmutter 28 und der Einsenkung 22 zu liegen kommt und den Schraubbolzenabschnitt 29 umgreift. From Fig. 2 also shows that the section 27, the longitudinal slot 19 of the base plate 7 carries, also angled in the direction of the inner circumferential surface 9 is, so runs on the same side as the depression 22. That way will it is possible, when flanging the recovery downpipes 1 and 2, the bottom plates 7 and 8 push together in the direction X, such that the longitudinal slot 19 between the screw nut 28 and the recess 22 comes to rest and the screw bolt section 29 grasps.

Die Befestigungsschraube 23 mit Mutter 28 wird ebenfalls werkseitig vormontiert und kann nicht verloren gehen, weil die darüber befindliche Schleißplatte 12 ein Herausfallen der Befestigungsschraube 23 verhindert. Nach dem Montieren der Bergefallrohre 1 und 2 und dem damit einhergehenden Zusammenschieben der Bodenbleche 7 und 8 wird die Mutter 28 festgezogen, was innerhalb kürzester Zeit geschieht. Wie ersichtlich ist, brauchen die Schleißplatten 12 und 13 nicht mehr demontiert zu werden, um die Bodenbleche 7 und 8 durch die Schraubverbindung miteinander zu kuppeln. The fastening screw 23 with nut 28 is also made at the factory pre-assembled and cannot be lost because the wear plate above it 12 prevents the fastening screw 23 from falling out. After assembling the Recovery downpipes 1 and 2 and the associated pushing together of the base plates 7 and 8, the nut 28 is tightened, which happens within a very short time. As can be seen, the wear plates 12 and 13 no longer need to be dismantled to be to the floor panels 7 and 8 by the screw connection to each other couple.

Eine Entkupplung der Teile geschieht in entsprechender Weise ebenso rasch und problemlos, wobei ebenfalls keine Schleißplatten 12, 13 demontiert zu werden brauchen.The parts are also decoupled in a corresponding manner quickly and easily, with no wear plates 12, 13 dismantled either will need.

Claims: 1. Spiral slide for washing mountains, in which several Rescue downpipes arranged coaxially to one another and connected to one another via flanges are and inside a helical spiral is arranged, the bottom plates attached to the inner jacket surface and arranged thereon There is wear plates and the base plates of directly adjoining recovery downpipes are coupled to one another via a screw connection, so that the floor panel of the one recovery pipe with its wear plates from the one mouth opening protrudes into the mouth of the other, neighboring recovery downpipe and the wear insert is flush against one another on the front side and without jumps, d a d u r c h g e -k e n n n z e i c h n e t that with the bottom plate (8) of a recovery downpipe (1) at least one fastening screw (23) permanently captive, but detachable, is connected, while the screw through hole of the associated adjacent Bottom plate (7) of the other recovery downpipe (2) than in the end face (18) of the Bottom plate (7) opening longitudinal slot (19) is formed such that the Fastening screw (23) with a screw bolt section (29) when joined together coaxially the recovery downpipes (1, .2) can be pushed into the longitudinal slot (19).

2. spiral chute according to claim 1, characterized in that the Fastening screw (23) with a countersunk head (24) in one facing the inner circumferential surface (10) of the relevant recovery downpipe (1) executed depression (22) arranged is and that the longitudinal slot (19) is at one on a portion (27) of the free End of the base plate (7) arranged formation is located, which is also to the inner lateral surface (9) of the relevant recovery downpipe (2) is executed.

Genus The invention relates to a spiral chute for washing mountains, in which several recovery pipes are arranged coaxially with one another and with one another via flanges are connected and arranged in their interior a helical helix is made up of floor panels attached to the inner circumferential surface and arranged thereon There is wear plates and the base plates of directly adjoining recovery downpipes are coupled to one another via a screw connection in such a way that the floor panel of the one recovery pipe with its wear plates from the one mouth opening protrudes into the mouth of the other, neighboring recovery downpipe and the wear insert abut against one another flush and without jumps on the front side.

PRIOR ART There are known spiral slides for mountains that consist of so-called recovery pipes exist that z. B. an inner diameter of 500 mm have and for the downward conveyance of wash mountains with z. B. a grain size from 0 to 80 mm and a conveying capacity of z. B. serve 250 to 320 m3 / h. The recovery downpipes are usually provided with inspection openings with sealing lids in order to work to be able to carry out inside the recovery downpipes, for example to wear plates to change or to clear clogs.

In the case of the previously known recovery downpipes, each recovery downpipe is on the one end designed in such a way that the helix arranged in it (bottom plate and wear plates) partially protrudes from the mouth opening at one end, while at the other Muzzle opening bottom plate and wear plate in the plane provided there Muzzle or end set back in the interior. When setting up the spiral slide the connection is made from such recovery pipes by the fact that the bottom plates be provided with coaxially superimposed through holes through which one screw is inserted and then tightened. Only then can the Place and fasten the wear plate provided here.

Such recovery downpipes are factory-fitted with pre-assembled coils, so assembled base plates and wear plates attached to them delivered. When assembling underground you now have to make the connection adjacent to each other To be able to manufacture recovery downpipes, the wear plates in the area of the joints are removed so that the screw connection of the floor panels is first established can be. The wear plates are then screwed back on in this area. The work required for this is dangerous and time-consuming because the work through the inspection openings with the heavy wear plates in the extremely cramped Spatial conditions must be carried out. The miner has to do the very heavy one Hold the wear plate through the narrow inspection openings and because of the steep incline the helix the wear plates, so to speak, with outstretched arms through the viewing opening pass through it and bring it down until the wear zone corresponds to the slope the coil comes into a position that it can be reattached. Since the work be carried out on a scaffolding, could be a misstep if improperly secured to be deadly. If the wear plate were let go, it could under certain circumstances falling many hundreds of meters and the inside of the helix in question strong damage or endanger deeper working miners.

The object of the invention is to provide a spiral chute for washing mountains where the disadvantages described no longer exist. A spiral chute according to the generic term should be designed so that the recovery downpipes are dangerous under the special conditions of underground mining. and can be assembled quickly and easily.

Solution The object is given by the claim 1 Features solved.
