Description

SPECIFICATION Device for consolidating a drift The invention refers to a device for consolidating a drift advanced by means of a cutting machine, in which device the consolidating frames are, in a substantially pre-assembled condition, transferred into the desired position by means of a transport and positioning means movable on a carrier supported on the cutting machine and are then placed in position by means of a lifting appliance. Such devices for the mechanized consolidation of a drift have, for example, become known from EP-A- 37 807.In this known construction, component parts of a provisional frame, i.e. in particular the caps and roof arches, respectively, were moved above the cutting machine till the drift face, noting that a telescopically expandable carrier adapted to be expanded in longitudinal direction of the drift was provided on the cutting machine and served as a shifting path for the transport and positioning means. With this construction it was not possible to simultaneously advance the side parts of a frame or, respectively, of props so that it was necessary for completing the drift consolidation to separately move in forward direction and past the drift advancing machine component parts of the consolidating frame. Such procedure represented a risk for the operating personnel and cutting work had still to be interrupted for a considerable time span.For increasing the degree of mechanization when consolidating a drift, there was proposed already in DE-A1-2 934 625 to laterally transport past a drift advancing machine a substantially pre-assembled frame by means of a transport device, noting that this frame could subsequently be placed in position within a plane transversally extending to the longitudinal axis of the drift after having lowered the cutting arm and after having swivelled said frame into said plane. The device required for such operation is still relatively expensive and the side parts of the consolidating frame must still be brought by an operating crew into a position in which this side parts can be connected with the cap.
The invention now aims at further improving the degree of mechanization of such devices and to provide the possibility to advance in direction of the drift face roof caps or, respectively, roof arches as well as the side parts of the consolidating frames in a mechanized manner and into a position in which the component parts must only be connected one with the other and must optionally be supplemented by inserting spacer members.For solving this task, the invention essentially consists in that the transport and positioning means has a platform being orientable relative to the carrier and being height-adjustable at least relative to the travelling plane of the transport and positioning means on the carrier, the lifting appliance for the roof caps or, respectively, roof arches of the consolidating frames and a transport means and positioning means for the side parts of the consolidating frames adapted to be displaced in axial direction of the drift being rested on said platform.
On account of the platform being orientable at least for height-adjustment and on account of the lifting appliance for the roof caps or, respectively, roof arches being supported against the platform, the platform can be adjusted independent of the lifting stroke of the lifting appliance for the roof arches or roof caps, respectively. On account of this platform carrying the transport means and the positioning means for the side- parts of the consolidating frame, these side parts can be brought in a correct position and be placed in position.A completely prepared roof cap or roof arch can, together with the required straining members such as wire meshes or plates, be forewardly moved above the drift advancing machine and be placed directly in the desired position without the necessity of being swivelled. For this purpose the cap of the frame need only be applied against the roof.On account of the side parts of the consolidating frame being moved in foreward direction by means of the transport and positioning means at the same time and in staggered manner as seen in the direction of the axis of the drift, also this side parts can be equipped with the desired straining members and completely be pre-assembled without risking when advancing these parts a collision with the cap portion, with the side wall of the drift or with the machine.
Completely pre-assembled parts of the consolidating frame can thus be advanced and the device according to the invention can, in contrast to known devices, immediately be used for positioning a final drift consolidation so that one can do without the expensive provisional drift consolidation. On account of the transport means for the side parts of the consolidating frame being designed for being displaced in axial direction of the drift, the side parts of the consolidating frame can be moved into the mounting plane of the consolidating frame and it is only required to establish the connection between the side parts and the roof cap or roof arch immediately within the area of danger located in proximity of the mine face.The thus required time expenditure is thus also substantially lower because the advanced sections of the drift consolidation can already be pre-assembled for being directly used, The correct position of the component parts of the consolidating frame can be adjusted relative to the drift profile and on account of the lifting appliance for the roof caps or roof arches as well as the transport means, being displaceable in direction of the axis of the drift, for the side parts being immediately supported on said platform, a pre-determined position of the roof cap or of the roof arch relative to the side parts of the consolidating frame can be adjusted, noting that by swivelling the transport means for the side parts of the consolidating frame it is easily possible to establish that relative position of the frame parts in which these parts can be connected one with the other.The operation can easily be automated so that the time loss caused by interrupting the cutting work is further reduced.
In this case, the orientable platform is preferably supported on the carrier for being inclined relative to the plane of travel of the transport and positioning means. The platform can in particular laterally be swivelled around the longitudinal axis of the carrier or, respectively, around an axis parallely extending relative to this longitudinal axis,and the plane defined by the platform can also be inclined relative to the plane of the floor for compensating any uneveness of the floor. The heightadjustability of the platform equally serves the purpose to compensate any uneveness of the floor and to obtain a starting position, starting from which the relative distance of the positioned cap from the side parts is exactly defined as seen in a preparatory condition swivelled into the plane of the positioned consolidating frame.In particular on account of the height adjustability of the platform being independent of the height adjustability of the separate lifting appliance for the roof caps or the roof arches, there results the premise for a fully automated working sequence in which swivelling of the side parts into the plane of the positioned caps immediately results in an alignment of the connecting areas between cap and side parts. A further equalization of any malposition of the drift advancing machine is preferably made possible by arranging the orientable platform for being swivelled around an axis intersecting the plane of travel on the carrier or, respectively, extending approximately perpendicular to this plane.Such swivelling of the platform around an axis crossing or intersecting the longitudinal axis of the carrier is particularly desirable if a machine is not exactly oriented in the longitudinal axis of the drift.
The lifting appliance for the roof caps or the roof arches may, according to the invention, comprise in a particularly space-saving manner two rocker arms arranged on the platform and having linked thereto a rocker arm carrying a support for the caps or roof arches to be placed in position and being supported against the platform by means of a pistoncylinder-aggregate. Such an arrangement is preferably geometrically designed as a straight-line mechanism, so that the caps are, while being lifted against the roof, applied against the roof exactly above the selected position of the platform. Such straight-line mechanisms are also named as lemniscate guides. An analogous arrangement can also be selected for the height-adjustability of the platform relative to the plane of travel so that there result smaller dimensions in height direction in a collapsed condition.
The arrangement according to the invention is in a particularly simple manner such that the transport means for transporting the side parts of the consolidating frame at both sides of the platform has at least one guide rod linked to the platform for being swivelled in longitudinal direction of the platform and being acted upon by a hydraulic cylinder-pistonaggregate pivotably linked to the platform.
The side parts of the consolidating frame are, to allow transporting same into the mounting position without contacting the floor fixed in position on the transport means in lifted condition. The guide rod pivotably supported on the platform simultaneously warrants a transport position in which the side parts do not collide with the side wall of the drift during advancing movement above the machine. The guide rods allow the side parts to be swiveilcd into the plane of the mounting position of the consolidating frames, noting that the guide rod again makes sure that the side parts do not collide with already positioned cap parts or roof arch parts during such swivelling movement.The side parts must, after having been swivelled into the plane of the positioned roof arch or roof cap, only be applied against the side wall in outward direction, noting that during this movement the side parts can simultaneously be downwardly moved in direction to the floor. For this purpose, the arrangement is preferably such that the side parts of the frames are connected to the guide rods for being adjusted in height direction and in the plane of the frame.A particularly simple construction for achieving such adjustability consists in that at both sides of the platform one pair of mutually parallel guide rods is pivotally linked to the platform and the free ends of the guide rods of one pair are connected by means of a head, in that a hydraulical cylinder-piston--aggregate is pivotably supported on the head for being inclined relative to the plane of the parallelogram formed of the guide rods and in that the side parts are connected to the free end of the cylinder-piston-aggregate, in particular that end of said aggregate which is adjacent the piston rod. For adjusting the inclination of these inclinable cylinder--piston-aggregate, a further hydraulic cylinder-piston-aggregate can be supported on the platform and the head, respectively.
For reducing the wear of the hydraulic cylinder-piston-aggregate applying the side parts against the side wall of the drift, the side parts of the consolidating frames can in an advantageous manner be adapted to be supported or connected to the free ends of the inclinable cylinder-piston-aggregate with inter position of a resilient member.
In place of the relativeiy expensive guiding means for the orientable platform a substantially simplyfied construction can be used in which the platform is height--adjustably supported on a column. Such height-adjustable column provides the possibility to arrange a platform for being universally pivotable and inclinable, noting that the column is advantageously height-adjustable and carries on its outer side a crowned bearing on which the platform is supported for being swingable.
Swinging of the platform relative to the column head of such a telescopically expandable and height-adjustable column can in a simple manner be achieved if the platform is supported on the column head by means of at least two hydraulic cylinder-piston-aggregates displaced in direction of the circuinfference of the column.
In the following, the invention is further illustrated with reference to an embodiment shown in the drawing. In the drawing, Figure 1 shows a side elevation of a drift as well as a side elevation of the partial cut cutting machine as well as of the movable transport and positioning means, Figure 2 shows a top plan view in direction of the arrow II of Figure 1, Figure 3 shows a front elevation of the drift as seen from the drift face and together with consolidating frame sections in their transport position, Figure 4 shows a platform for the lifting appliance in a side elevation, Figure 5 shows a view of the platform of Figure 4 in direction of the arrow V of Figure 4, Figure 6 shows a view of Figure 5 in direction of the arrow VI of Figure 5, Figure 7 shows a detail of the separate transport means for the side parts of the consolidating frames, Figure 8 shows a view of the arrangement according to Figure 7 in direction of the arrow VIII of Figure 7 Figure 9 shows a lifting means for the roof caps or the roof arches in a side elevation, Figure 10 shows a side elevation of the drift like Figure 1 together with a modified embodiment of the transport and positioning means, Figure 11 shows a top plan view of the arrangement according to Figure 10, Figure 1 2 shows a view in direction of the arrow XIII of Figure 10, Figure 14 shows a section along line XIV-XIV of the arrangement according to Figure 10 and Figure 1 5 shows a detail of the connection of the side parts to the transport means according to Figure 10.
In the drift shown in Figure 1, a partial cut cutting machine 2 can be moved in longitudinal direction of the drift. A cutting head 4 is supported on a cutting arm 3 and can, if the transport and positioning means 5 is moved back in its left-hand position, work the whole drift face 6. The transport and positioning means is once shown in its position 5' at the left-hand end of the plane of travel of the carrier 7, in which position pre-assembling of the individual consolidating parts is effected.
The transport and positioning means is, with the cutting arm 3 adjusted to a substantial horizontal position, advanced into the positioning position in which the transport and positioning means is shown at the right-hand side of Figure 1. Under this condition, the carrier 7 is supported on the cutting machine 2 and on the cutting arm 3. The transport and positioning means has a platform 8 which is orientable relative to the plane of travel on the carrier 7. The connection areas 9 for the side parts of the consolidating frame and the lifting appliance 10 for positioning the roof arch or the roof cap 11 are supported on this platform 8. The chassis of the transport and positioning means is designated by 12.
In the top plan view of Figure 2, there is also shown the carrier 7 on which the transport and positioning means 5 can be moved.
Figure 2 again shows the transport and positioning means 5, the cap 11 being shown together with a distortion mesh 1 3. At a distance behind the plane 14 of the positioned caps 11, the side parts 1 5 already being equipped with distortion meshes 1 3 are advanced by means of the transport and positioning means 5. The lower half of Figure 2 shows that these side parts 1 5 are advanced behind the roof caps 11 from a position displaced in direction of the axis 1 6 of the carriers 7,noting that the separate transport means for the side parts 1 5 has guide rods 1 7 pivotably linked to the platform 8.In the upper half of Figure 2, these guide rods 1 7 are shown as having been forewardly swivelled in mounting position, and a hydraulic cylinder-piston-aggregate 39 is provided by means of which the side parts can be applied against the side wall 1 9 of the drift. As can be taken from Figure 3, the side parts 1 5 of the consolidating frame are advanced in lifted position and at a distance from the side wall 1 9 of the drift simultaneously with the caps 11 into positioning position. As seen from the drift face in direction of the drift, the side parts 1 5 are in transport position behind the caps. The drift advancing machine or partial cut cutting machine is schematically shown with the profile of its cross section and designated by 2.
The platform 8 of the transport and positioning means is shown in Figure 4 in an enlarged scale. In the position 8' shown in dashed lines, in which the platform is lowered for transport purposes, the platform 8 is supported on the base construction by means of guide rods 20 and 21 as well as by means of a hydraulic cylinder-piston-aggregate 22. In the lowered position, the guide rods are designated by 20' and 21' and the cylinder-pistonaggregate is designated 22'. The hydraulic cylinder-piston-aggregate 22 allows to lift the platform from the position 8' into the position shown in full lines and to lower the platform, and this in direction of the twin arrow 23. The platform is linked to the upper guide rod 21 of the drive means for height-adjustability so as to be inclinable around an axis 24 transversally extending relative to the longitudinal axis of the drift.A further cylinder-piston-aggre gate 26 acting on the platform and thereby being swivellable around an axis 27 is con nected by means of a flap 25. Actuation of the cylinder-piston-aggregate 26 thus causes a change of the inclination of the platform relative to the plane of travel of the carrier 7 in the sense of the twin arrow 28. The platform 8 is supported on a turntable 29 rotatably supported within the chassis 1 2 of the transport and positioning means, the rotatable support being formed of a swivelling pin 30 being substantially perpendicularly arranged relative to the longitudinal axis 1 6 ob the carrier 7. Swivellability of the platform 8 around an axis parallely extending relative to the longitudinal axis 1 6 of the carrier 7 is shown in Figure 5.Figure 5 again shows the turntable 29 on which the swivelling pin 38 is rotatably supported. A cylinder-piston-aggregate 31 is provided for swivelling the platfform 8 in the sense of the twin arrow 32.
On the platform 8, the lateral linking point 33 for the guide rods 1 7 can be seen. Rotation of the platform 8 around an axis 34 is effected by means of a hydraulic cylinder-piston-aggregate 35 acting on the turntable 29 as is clearly shown in Figure 6.
Figure 7 shows the side edge 36 of the platform 8 on which are provided the linking points 33 for the parallelogram guide rods 1 7. The guide rods 1 7 are linked to the platform 8 so as to be swivellable around axes 33 and have a head 38 on their free ends. A hydraulic cylinder-piston--aggregate 18 is connected to this head 38 for being inclinable relative to the plane defined by the guide rods 1 7. The free end of this hydraulic cylinderpiston-aggregate carrries the side parts 1 5 of the consolidating frame indicated by dashed lines.Swivelling movement of the guide rods 1 7 is effected by means of a hydraulic cylinder-pistonaggregate 39 acting on one of both guide rods 1 7 and being connected with the platform 8 via a bearing eye 40. During swivelling movement, the position 17' is reached in which the side parts 1 5 enter the plane of the positioned caps 11. On account of the geometry of the parallelogram guide rods 1 7,swivelling must, for making sure a sufficient distance from the side wall of the drift, be effected in a position in which the hydraulic-cylinder-piston-aggregate is retracted.By actuating the hydraulic cylinderpiston-aggregates 18, the side parts 1 5 can then be applied against the side wall of the drift, noting that by inclining the cylinderpiston-aggregate 1 8 relative to the plane of the paraparallelogram guide rods 17, the side parts are allowed to be moved in outward and downward direction. Adjustment of the inclination of the cylinder-piston-aggregate 1 8 is effected by means of a further cylinder-pistonaggregate 41 connected to the platform 8 and acting on the free end of the cylinder-pistonaggregate 18. This is further explained with reference to Figure 8.In the representation of Figure 8, the platform is again designated by 8 and the transport position of the side parts 1 5 as well as of the hydraulic cylinder-pistonaggregate 18 is shown in full lines. After having swivelled the guide rods 1 7 into the plane of the positioned caps, the cylinderpiston-aggregate 78 is swivelled into the position 18' shown in dashed lines, so that the side parts 1 5 are brought into that position in which the cap 11 can be connected with the side parts 1 5. In this position it is only necessary to complete the connection between the cap 11 and the side parts 15, whereupon the cylinder-piston-aggregate 18 can be loosened from the side parts 1 5 and again be retracted.The cylinder-piston-aggregate is thus backwardly swivelled from the position 18' into the position 1 8 and thus arrives the starting position in which the side parts 1 5 can, in mounting position, be correctly connected in correct lateral position and correct height position.
In the representation of Figure 9, a lifting appliance for the roof caps 11 is schematically illustrated. The lifting appliance 10 is supported on the platform 8 and has two rocker arms 42 and 63 pivotably linked to the platform 8. A rocker arm 43 is pivotably linked to the rocker arms 42 and 63. These rocker arms are supported against the platform 8 by means of a piston-cylinder-aggregate 44. This results in a lemniscate guide which, with an only small space requirement of the lifting appliance in collapsed or retracted condition, allows to cover a relatively great height a, thereby maintaining with great exactness the conditions of a straight-line motion.The correct swivelling position of the caps 11 can, in this case, be adjusted by means of an adjustable auxiliary guide rod 45 by means of which in correspondence with the predetermined height a the correct swivelling position of the caps 11 can be pre-determined by means of a tension jack 46. For further reducing the space requirement, the upper rocker arm 43 is cranked.
In the device according to the invention the plane of the platform 8 is first adjusted in accordance with the possibilities explained by the Figures 4, 5 and 6 by actuating the hydraulic cylinder-piston-aggregates 22, 26, 31 and 35. Starting from this position, the lifting appliance 10 is extended for its predetermined stroke a, which can now be dimensioned such that swivelling the guide rods 1 7 having attached thereto the side parts immediately results in the mounting position as soon as the side parts have been applied against the side wall 19 of the drift by means of the hydraulic cylinder-piston-aggregates 18.
After having established the connection between cap and side parts, the lifting and positioning means can again be swivelled back into its starting position and moved back into a position behind the machine where further pre-assembling can be effected within a protected area.
In the embodiment according to Figure 10, the cutting machine designated by 2 is again shown. The positioning and transport means 47 is with this embodiment supported on a height-adjustable column- 48 and can be moved along a path 7. The pre-assembled side parts 1 5 of the frame as well as the preassembled roof caps 11 are put by means of a mounting crane 49 onto the backwardly moved positioning and transport device 47 and are subsequently moved into'the right-.
hand position of Figure 10, whereupon thc column 48 is first lifted in an analogous manner as described in connection with Figure 1 and 2 and the roof cap is then placed in position.
In the representation of Figure 7, there are also shown the parallelogram guide rods 17, the swivelling and applying cylinder for the side parts 1 5 again being designated by 1 8.
For the purpose of an unobjectionable energy supply, a draw cable chain 50 shown in Figures 10 and 11 is provided. In Figure 11, the side parts 1 5 are shown in their righthand-end position and as being swivelled into the plane of the frame and as being brought in their correct position.
In Figure 12, the column 48 is fixed to a turntable 29, the rotation drive again being designated by 35. A hydraulic cylinder-pistonaggregate 51 is shown, by means of which can be adjusted the inclination of the platform 8. In the representation of Figure 12, the roof caps 11 are placed in position. The head 38 connecting both guide rods 1 7 of the transport means for the side parts 1 5 carries the swivelling axis for the hydraulic cylinder-piston-aggregate 1 8,by means of which the side parts 1 5 are swivelled and applied against the drift wall, swivelling movement being effected by means of a cylinder-piston-aggregate 52 equally supported on this head 38. For receiving hard shocks, resilient shock-absorbent elements 53 are provided at the end of the piston rod.
In the embodiment of Figure 13, there is again shown the mounting crane 49 in a position rotated for 90 . By means of this mounting crane 49, completely assembled roof caps 71 as well as the side parts 1 5 can be fixed to the positioning and transport means 47, the side parts 1 5 being in transport position again arranged behind the cap 11. The mounting crane is supported on a cross beam 54 at the rear end of the carrier 7.
In Figure 14, the height-adjustable column is shown in an enlarged scale. The heightadjustable column is connected with the turntable 29, the rotating drive again being indicated by 35. Within the interior of the heightadjustable column, a hydraulic piston 55 is guided,and its associated working space is designated by 56. When pressurizing the working space 56, the head 57 of the heightadjustable column 38 is moved in direction of the arrow 58. At the exterior of the head 57, a crowned bearing 59 is fixed onto which the platform 8 is supported. A swivelling cylinder 41 is shown which allows to incline the platform 8 relative to the column 48.In an analogous manner, a second hydraulic cylinder-piston-aggregate is arranged and displaced for 90 in circumferential direction, said aggregate serving to effect in an analogous manner an inclination transverse to the inclination as can be effected by the shown hydraulic cylinder-piston-aggregate 51. This second cylinder-piston-aggregate is not shown in the drawing.
Figure 1 5 shows in an enlarged scale the connection of the side parts 1 5 to the end of the hydraulic cylinder--piston aggregate 18.
The shock-absorbing element 53 is connected with the side parts 1 5 of the frame via a link 60 and acts in off--center position and via a flap 61 on that end of the cylinder-pistonaggregate which is located at the side of the piston rod. The immediate pivotal link of the side parts 1 5 to the end of the hydraulic cylinder-piston-aggregate 1 8 at its end located at the side of the piston rod is effected by means of flaps 62.
