Es sind fahrbare Schrämvorrichtungen bekannt , bei welchen das Werkzeug· in senkrechter Richtung verstellbar sowie wagerecht schwenk- oder drehbar angeordnet ist. Die Verstellbarkeit, die hierbei in senkrechter Richtung erzielt wurde, genügte aber nicht; eine Vervollkommnung in dieser Beziehung bildet den Gegenstand der vorliegenden Erfindung, deren Wesen darin besteht, daß ίο das einer vollständigen Umdrehung fähige Werkzeug mit seinem Antrieb sowohl oberals auch unterhalb eines der Höhe nach verstellbaren Rahmens befestigt wird, so daß es das Kohlenflöz in den verschiedensten Höhenlagen zu schneiden vermag.There are known mobile cutting devices in which the tool · in a vertical Direction adjustable and horizontally pivotable or rotatable. The adjustability here in vertical Direction was achieved, but not enough; a perfection in this respect forms the subject of the present invention, the essence of which is that ίο the tool capable of a full turn with its drive both above and is also attached below a height-adjustable frame, so that it able to cut the coal seam at various altitudes.

Auf den Zeichnungen ist der Gegenstand der Erfindung veranschaulicht. Es zeigt:The subject matter of the invention is illustrated in the drawings. It shows:

Ausführungsform des Antriebes mit dem Schneckenrad, welches zum Schwenken des Werkzeuges dient, in Ansicht und im Schnitt.Embodiment of the drive with the Worm wheel, which is used to swivel the tool, in view and in section.

Der Schneidarm α ist unmittelbar mit der Welle b des Motors verbunden oder mit ihr gekuppelt. An dem Motor ist ein als Schneckenrad ausgebildeter Ring c angeordnet. Letzterer ruht in einer Aussparung des Hauptrahmens d der Maschine, der sich in bekannter Weise in senkrechter Richtung an den Pfeilern η der Laufräder der Maschine verstellen läßt. Der zur Anwendung kornmende Motor kann ein beliebiger sein. Bei dem gezeichneten Beispiel ist ein Elektromotor zur Verwendung gelangt.The cutting arm α is directly connected to or coupled to the shaft b of the motor. A ring c designed as a worm wheel is arranged on the motor. The latter rests in a recess in the main frame d of the machine, which can be adjusted in a known manner in the vertical direction on the pillars η of the running wheels of the machine. The motor used can be any motor. In the example shown, an electric motor has been used.

Das Schneckenrad bezw. der Ring c, an welchem der Motor hängt, steht mit einer Schnecke e der Welle f in Eingriff, die ihrerseits ein Schneckenrad trägt und durch eine mit einem Handrad oder dergl. versehene Schnecke g in Umdrehung gesetzt wird. Durch Drehen der Schnecke g kann daher der Antriebsmotor mit dem Werkzeug gedreht werden.The worm gear respectively. the ring c, on which the motor hangs, is in engagement with a worm e of the shaft f , which in turn carries a worm wheel and is set in rotation by a worm g provided with a handwheel or the like. By rotating the worm g , the drive motor can therefore be rotated with the tool.

Bei Herstellung eines Schrames wird das Werkzeug zweckmäßig so eingestellt, daß es in einem spitzen Winkel zur Mittellinie der Maschine steht. So wird das Werkzeug in Richtung der Linie A-B (Fig. 4) einzustellen sein, wenn sich die Maschine in der durch den Pfeil C angedeuteten Richtung vorwärts bewegt, während die Richtung der Linie D-E zu wählen ist,· wenn die Maschine in der durch den Pfeil F angedeuteten Richtung arbeitet. Um das Getriebe von dem Stoß und dem während des Abschneidens des Flözes entstehenden Druck möglichst zu entlasten, kann der Maschinenrahmen mit demWhen making a Schrames, the tool is expediently set so that it is at an acute angle to the center line of the machine. Thus, the tool will have to be adjusted in the direction of the line AB (FIG. 4) when the machine moves forward in the direction indicated by the arrow C , while the direction of the line DE is to be selected when the machine is in the direction indicated by the arrow C Direction indicated by arrow F is working. In order to relieve the transmission of the impact and the pressure generated during the cutting of the seam, the machine frame with the

Claims

Motor housing are rigidly connected. For this purpose, respectively, are on the machine frame d. on the motor housing. I noses or projections It i and jk provided which are provided with openings for the purpose of receiving bolts.

The motor shaft b carries a drive. disk m for the feed device, which is not shown.

ίο The connection of the machine frame d with the girders or pillars η for the running wheels is effected by support pieces ο which can be raised and lowered in a known manner by screw spindles ρ guided in nuts q.

Each beam or pillar η is provided with two pins r arranged at right angles to one another, the purpose of which is to enable the device to be moved both in the longitudinal direction and in the transverse direction by repositioning the running wheels.

The height of the beam η and the length

of the spindles ρ is dimensioned so that the cutting tool is suspended below the machine frame and adjusted in height if the bevel is to be made between 250 and 500 mm above the upper edge of the rail. If you want to cut between 850 and 1150 mm above the top edge of the rail, the tool is placed on the machine frame and its height is adjusted.

The cutting in the height of the seam between 500 and 850 mm above the upper edge of the rail can be effected by reversing the main frame of the machine d in the support pieces 0 (Fig. 3) so that the surface s comes to lie up.

If you want to cut from the upper edge of the rail up to a height of 250 mm above the upper edge of the rail, the axis t of the tool is arranged below the motor and driven by an intermediate gear, as shown in FIGS. 5 and 6.

If the motor with the tool is arranged above the machine frame, it can easily be given a circular movement by means of the ring c and the worms e and g; However, if it is suspended below the machine frame, it is necessary for this purpose to remove the pillars η one after the other. In this case, if the cutting tool is in the seam, it is unnecessary to undertake the machine frame at the corner where a pillar has been removed; because the fact that the cutting arm is supported prevents the machine from tipping over.

If the machine is to cut a seam in a laterally exposed seam, so the cutting arm will find its way into and out of the seam by itself break out.

In order to move the machine in the transverse direction against an existing coal seam, the pillars η are lifted one after the other (by means of the aforementioned screws ρ 'and nuts q) in order to remove the rail wheels from the usual axle journals and place them on the other axle journals r allow. After all four wheels have been moved in this way, the whole machine can easily be moved forward on suitable cross rails provided for this purpose until it has reached the desired new position.
