Abstract
On a cutting machine there is arranged a transport path for a manipulator (8) by means of which gallery arches can be moved from a rear position to a front position and can be placed in position. The transport path is subdivided at the area of the connection point (25) of the cutting arm (1) to the frame (2) of the cutting machine into a rear transport path portion (5) and a front transport path portion (6). The rear transport path portion (5) is, with its front area, supported on the frame (2) of the cutting machine and can, at its rear area, be supported on the floor by means of struts (11). The front transport path portion (6) is supported on the cutting arm (1). Between the front transport path portion (6) and the rear transport path portion (5) there is provided an intermediate transport path portion (7) which can be removed from the stretched transport path, so that the front transport path portion (6) can be brought in an angular position relative to the rear transport path portion (5) and the cutting arm can be swivelled without obstruction during operation. <IMAGE>
Description
SPECIFICATION
Device for Placing Gallery Arches
The invention refers to a device for placing gallery arches at the area of a partial cut cutting machine, comprising a transport path supported on the cutting machine and adapted to have displaced thereon in longitudinal direction of the cutting machine, for example by rolling movement or sliding movement, a carriage equipped with a manipulator for component parts of a gallery arch.
Such devices for the mechanized consolidation of a gallery or drift have, for example, become known from EP-A-37 807. In this known construction, component parts of a provisional frame, in particular the caps or roof arches, have been moved to the drift face above the cutting machine, noting that a carrier telescopically expandable in longitudinal direction of the drift was provided on the cutting machine as a shifting path for the transport and consolidating means.
To provide for an unobstructed pivotability of the cutting arm, the carrier was supported on the frame of the cutting machine or on the traversing gear of the cutting arm and the telescopically expandable part of the carrier freely extended in a cantilevering manner of the cutting arm. The load capacity of the end of the carrier was thus limited.
On account of said limited load capacity it was not possible with such a construction to simultaneously advance the lateral parts of a frame or, respectively, the props. For completing the drift consolidation it was therefore necessary to separately advance past the drift advancing machine component parts of the consolidating frame. By such a mode of operation, the operating personnel was endangered and the cutting work had still to be interrupted for a substantial time interval.For increasing the degree of mechanizing drift consolidating work it has already been proposed in DE-Ai-2 934 625 to transport past a drift advancing machine an extensively preassembled frame by means of a transport device so that this frame could be placed within a plane transversely extending relative to the longitudinal axis of the drift after having lowered the cutting arm and having swivelled this frame into said plane. The manipulator for transporting the frame and placing same in position could be moved on a transport path rigidly supported on the cutting machine, but this transport path could only be advanced till the transversing gear of the cutting arm for not detracting from the free pivotability of the cutting arm.The frames could thus only be advanced for a limited path so that the drift roof could not be supported in proximity of the excavating face or drift face. The equipment required for advancing the frames and placing same in position was still relatively expensive and the side parts of the consolidating frame had still to be brought by operating personnel into a position for being connected with the cap.
It is an object of the invention to increase the load capacity of the transport path and to provide the possibility to advance the consolidating frames or their component parts, respectively, as near as possible to the excavating face.
In this connection the invention essentially consists in that the transport path is suvdivided at the area of the connection point of the cutting arm to the frame of the cutting machine into at least one rear transport path portion and at least one front transport path portion adapted for being brought into an angular position relative to the
rear transport path portion and being supported on the cutting arm at least within its front area.
On account of the front transport path portion being supported on the cutting arm at its front area, it is made possible to advance the transport path nearly completely in direction to the cantilevering end of the cutting arm and to increase the load carrying capacity of the transport path to such an extent that also the foremost end of the transport path can receive the forces required for placing in position the consolidating arches and that placing of the just foremost consolidating arch can be effected in very close proximity of the drift face. This increase of load carrying capacity is also sufficient to receive the combined weight of the roof arch and of the side parts of the consolidating arch or of -the props, respectively, so that the side parts can be transported in forward direction together with the roof arch. The security is thus increased.On account of the transport path being subdivided into at least one rear transport path portion and at least one front transport path portion adapted for being brought into an angular position relative to the rear transport path portion, the cutting arm is not obstructed from its universal pivotability during the cutting work in spite of the front transport path portion being supported on the cutting arm. The front transport path portion can follow all pivotal movements of the cutting arm without detracting from the pivotability of the cutting arm.
For providing universal pivotability of the cutting arm together with the front transport path portion, the swivel joint between the front transport path portion and the rear transport path portion must correspondingly be designed. For example, the rear end of the front transport path portion could be lifted so that this rear end does not collide with the front end of the rear transport path portion when swivelling the cutting arm.
According to a preferred embodiment of the
invention the arrangement is, however, such that the front transport path portion is also supported on the cutting arm at the rear area of the cutting arm and that between the rear transport path
portion and the front transport path portion there
is arranged an intermediate transport path portion which can be removed from the stretched transport path. By removing this intermediate transport path portion, a gap is provided between the rear transport path portion and the front transport path portion so that the cutting arm is not obstructed from being universally pivotable. In the stretched position of the transport path this gap is, however, closed by the intermediate transport path portion, so that the carriage can, without any obstruction, move in longitudinal direction of the stretched transport path.In this case and according to the invention, the arrangement can be such that the intermediate transport path portion is linked by means of a horizontal axis located at its rear end to the horizontal traversing gear of the cutting machine for being swivelled around this horizontal axis, that the rear end of the intermediate transport path portion is delimited approximately by an arc of a circle having its center coinciding with the vertical pivotal axis of the cutting arm and that the front end of the intermediate transport path portion extends with a chamfer over a chamfer provided on the rear end of the front transport path portion.By delimiting the rear end of this intermediate transport path portion along an arc of a circle having its center coinciding with-the vertical pivotal axis of the cutting arm, the horizontal traversal gear of the cutting machine can be swivelled around the vertical pivotal axis of the cutting arm. On account of the rear end of the intermediate transport path portion being pivotally linked to the horizontal traversing gear for being swivelled around a horizontal axis and on account of the front end of the intermediate transport path portion extending with its chamfer provided on its front end over a chamfer provided on the rear end of the front transport path portion being supported on the cutting arm, it is also made possible to upward swivel the cutting arm in an unobstructed manner.In case of such swivelling movement of the cutting arm, the intermediate transport path portion is simply lifted in upward direction and slides over the rear part of the front transport path portion, thus releasing the latter. It is thus made possible to universally swivel the cutting arm during cutting work, whereas in stretched position of the cutting arm (transport path) the transport path is closed and the manipulator can unobjectionably be moved along the transport path from the rear end of the rear transport path portion to the front end of the front transport path portion.
According to a preferred embodiment of the invention, the rear transport part portion is supported with its front area on the frame of the cutting machine and can be supported with its rear area on the floor. In this case and according to the invention, at least one hydraulically positionable strut or prop is conveniently provided for such support on the floor. The rear transport path portion is of relatively great length and a static redundancy caused by the strut or prop supported against the floor can thus be avoided by elastically receiving movements also with a stationary support of the front end of the rear transport path portion on the frame of the cutting machine. According to the invention, the rear transport path portion is, however, supported for universal pivotal movement on the frame of the cutting machine at the area of the vertical pivotal axis of the cutting arm.On account of the rear end of the rear transport path portion being supported on the floor, vibrations generated during operation of the cutting machine are not transmitted to this rear end. This rear end rests quiet and it becomes thus possible to put the component parts of the gallery arch on the backwardly moved manipulator and to preassemble these component parts without being disturbed by vibrations. During such preassembling, the roof portion or cap of the gallery arch can, for example, be assembled of individual parts and distortion plates or distortion meshes can already be fixed to this roof portion or cap.
Also connecting members for subsequently connecting the side parts of the gallery arch to the roof portion can be mounted on the roof portion and distortion plates or distortion meshes can be fixed to the side parts while these are hanging on the manipulator. On account of the rear end of the rear transport path portion being maintained in quiet position by the strut or prop positionable on the floor, all these manipulations can be performed by the operator without being disturbed by vibrations.
An arrangement suitable for particularly reliably preventing any obstruction of the swivelling movement of the cutting arm by the transport path can, according to the invention, be obtained by arranging between the rear transport path portion and the front transport path portion supported on the cutting arm an intermediate transport path portion being swivellable by means of a swivelling drive around an axis intersecting or crossing the longitudinal axis of the transport path. In this manner, any collision of individual parts of the transport path can be excluded during cutting work if the intermediate portion is swivelled prior to swivelling the cutting arm.In ;his case, the arrangement can in a simple manner be such that the intermediate transport path portion is pivotably linked to the rear transport path portion or to the front transport path portion and preferably to the front transport path portion, noting that the intermediate transport path portion is preferably adapted to be swivelled by means of a hydraulic cylinder-pistonaggregate acting on the cutting arm.
In the drawing the invention is schematically illustrated by an embodiment.
Figure 1 shows a side elevation of a partial cut cutting machine positioned within a drift consolidated by means of gallery arches, the manipulator being shown in full lines in its consolidating position and being shown in dashed lines in its retracted position in which the component parts of the gallery arches are being pre-assembled. Figure 2 shows a top plan view of the partial cut cutting machine according to
Figure 1 and Figure 3 shows a detail of the transport path.
Figures 1 and 2 show the cutting arm 1 of the partial cut cutting machine in the stretched position of the transport path in which the gallery arches are being positioned. 2 is the frame of the partial cut cutting machine, 3 are gallery arches already being placed in position. 4 represents a gallery arch to be placed in position.
A manipulator 8 can be moved on a transport path 5, 6, 7. This manipulator 8 is shown in full lines in its operating position while placing a gallery arch in position. This manipulator is shown in dashed lines in its backward moved and collapsed position 8'. In the shown position of the cutting arm and of the frame of the cutting machine, this manipulator 8 can be moved from the rear end of the transport path till the front end of the latter.
5 is the rear transport path portion, 6 is the front transport path portion and 7 is an intermediate transport path portion. In the position shown, these transport path portions extend along a straight line, so that the manipulator is not obstructed in its movability.
The rear transport path portion is supported at 9 on the frame 2 of the cutting machine for being slightly swivable in all directions at the area of the vertical pivotal axis 10. This rear transport path portion 5 is supported at its rear end against the floor 12 by means of hydraulic struts or props 11.
The struts or props 11 act on the rear transport path portion 5 with interposition of a cross head 13. The rear end 14 of the rear transport path portion 5 is, on account of being supported on the floor, maintained quiet also during cutting work, so that the various parts of the gallery arch to be put in position next can be pre-assembled on the manipulator 8 assuming the position 8' without being disturbed by vibrations. The roof portion of this gallery arch 4 to be placed in position is designated by 15 in Figure 2. The side parts are designated by 1 6. The right-hand side part 16 is still in its backward swivelled position, while the left-hand side part 16' has already been swivelled into the plane of the gallery arch 4.The roof portion 1 5 of the gallery arch is composed of several individual parts, and distortion plates or distortion meshes 1 7 are fixed to the roof portion 1 5 and to the side parts 16 if these are placed on the manipulator 8 still being in the position 8'.
As already mentioned, the transport path 5, 6, 7 is. uninterrupted in the position shown in the drawing of the partial cut cutting machine 1, 2 so that the manipulator 8 can without difficulties be moved from the rear end till the front end.
The front end of the rear transport path portion 5 is approximately limited along an arch 18 of a circle having its center coinciding with the vertical pivotal axis 10. The intermediate transport path portion 7 is linked to the horizontal traversing gear 1 9 for being swivelled around a horizontal axis 20. Such delimitation 18 having the shape of an arc of a circle provides the possibility to swivel the cutting arm 1 around the vertical pivotal axis 10 during cutting work. On account of the connection between the front transport path portion 6 and the intermediate transport path portion 7 being interrupted at 21 , the cutting arm 1 can, without being obstructed, be swivelled in downward direction during cutting work.The intermediate transport path portion 7 extends at 21 with a chamfer 22 over a corresponding chamfer of the front transport path portion 6. If now, during cutting work, the cutting arm 1 is swivelled in upward direction, the front end of the intermediate transport path portion 7 slides in upward direction on the front transport path portion 6 and releases the cutting arm 1 for being swivelled in upward direction. The front transport path portion 6 is supported at the area of the front end of the cutting arm 1 at 23 and on the rear end of the cutting arm at 24. The intermediate transport path portion makes the cutting arm 1 universally swivellable during cutting work in spite of said supporting areas. 25 is the horizontal swivelling axis to which the cutting arm is pivotally linked on the horizontal traversing gear 1 9. 26 is the entry of the transport means of the cutting machine.
In Figure 3, the intermediate transport path portion 7 is pivotally linked to the front transport path portion 6 for being swivelled around an axis 27 intersecting the transport path, noting that the front transport path portion 6 is again supported on the cutting arm 1. The intermediate transport path portion 7 has on its bottom side 28 facing the cutting arm a fiap 29 for the engagement of a hydraulic cylinder-piston aggregate 30 being supported on the cutting arm 1. By means of this hydraulic cylinder-piston-aggregate 30, the intermediate transport path portion 7 can be swivelled in upward direction and in direction of the arrow 31 around the axis 27, so that swivelling movement of the cutting arm 1 in direction of the arrow 32 does in this position not result in a collision of the individual transport path portions.
The rear transport path portion 5 is pivotably supported on the machine frame for being swivelled around an axis 33 formed of a bearing neck. The abutment is formed of a column 34 which is optionally adjustable in height. As a rule, this abutment is supported on a stationary part of the machine frame. If the abutment is provided on the transversing gear itself, this abutment must be arranged in alignment with the axis of the traversing gear and be pivotable around this axis of the traversing gear.
