Description

DESCRIPTION

Roller skid loader with integrated anchor setting unit

The invention relates to a roller charger for use in mining, with a frame having the ends of mining rollers and serves to accommodate at least one drilling / Ankersetzeinheit.

In the underground process of such Walzenschrämlader as

Mining coal miners in the longwall are milled or cut coal from the wall of the seam. For this purpose, such a roller loader on the front sides of its frame rolls as

Editing tools on. In such degradation measures, it is in

Interaction with the shield removal often necessary to secure the hanging wall and the impact of an armature removal. In this context, it is known to equip the roller chargers with a drilling / Ankersetzinheit. For this purpose, such a unit is placed if necessary on the frame of the shearer and fixed there, which is associated with some effort during assembly and subsequent disassembly. In addition, the scope of such, installed on the frame of the shearer loader drilling / Ankersetzeinheit is limited primarily by the fact that the rock outside the contours of the shearer loader is virtually impossible to achieve. It is obvious that it is therefore in practice in view of the often necessary to move the shearer between the pursuit of unnecessary time losses and even downtime and beyond also the endangerment of personnel especially in the hitherto necessary manual drilling, Ankersetz- and other work outside the contours of the actual loader comes. Thus, the present invention has the object to provide a device for use in mining, which allows fast and safe drilling or Ankersetzen in connection with the use of a roller charger.

This object is achieved in that the drilling / Ankersetzeinheit is arranged movably on the frame of the roller charger, with

End positions of the drilling / Ankersetzeinheit in the form of a parking position within the contours of the frame and a maximum working position outside the contours of the frame and beyond the mining rollers.

While previously known drilling / Ankersetzeinheiten had to be installed on the frame of the roll chargers in case of need and also were extremely limited in their movement possibilities, the invention now provides that the roller charger with at least one drilling / Ankersetzeinheit

is equipped, which is arranged on the frame of the roller charger between a plurality of practically arbitrary positions movable. As one

End position is provided a parking position within the contours of the frame, where the drilling / Ankersetzeinheit is positioned when it is not in use, for example, during the Schrämens. From there, it can be moved into a multitude of, ultimately, unlimited working positions.

pivoted, in which the drilling / Ankersetzeinheit can also be located outside the contours of the frame and even beyond the mining rollers.

Thus, it is now also possible for the drilling or bolting operation to reach the previously unreachable according to the prior art, reaching to the distances zones. Now anchoring is also possible beyond the frame, ie behind the respective roller and thus in a particularly endangered area. The mechanical use also has the effect that no more persons are endangered.

It is particularly useful when on the frame of

Roller chargers two drill / anchor set units are provided, which despite it the cramped space allows it to run over a maximum range with the drilling / Ankersetzinheiten to use this outside the contours of the frame can. The two units can be controlled independently of each other and thus also in parallel, via remote control or radio, fully or electro-hydraulically moved and controlled for drilling or Ankersetzen.

For this purpose, it is provided that the frame has at least one sliding track for the drilling / Ankersetzeinheit on which the respective drilling / Ankersetzeinheit can be moved.

With respect to the preferred embodiment with two separate drilling / anchor setting units, it is recommended to use on the frame of the

Roll loading device two sliding tracks are provided, on each of which a drilling / Ankersetzeinheit is arranged movable.

It is thought that as possible, the moving tracks are arranged in a common axis, ie in the form of in a run

one behind the other on the frame positioned moving tracks.

This range is also significantly increased by the fact that one or more drilling / Ankersetzinheiten are arranged on a slide formed on the sliding carriage. By positioning the drilling / Ankersetzinheiten on a slide additional leeway is created, especially in conjunction with the adjustability of

Sliding track.

A particular advantage of the invention is that in a measure to increase the range of the drilling / Ankersetzeinheiten track and / or carriage are designed to be adjustable in length over a linear drive. Due to the lengthening of the respective sliding track or the method of the carriage, additional space for positioning the drilling / Ankersetzeinheiten be achieved by the movement track can also over the contours of the frame, over this projecting, moved. Thus, the respective drilling / Ankersetzeinheit is movable in a position at least partially above the rollers on the extended displacement track.

With regard to the adjustability or mobility of the sliding track and slide, it is proposed that a hydraulic cylinder, a chain drive or a toothed drive be used for adjusting the sliding track and / or for moving the carriage. Other forms of drive are conceivable.

In order to reduce the total number of units present on the roller loader according to the invention, it is envisaged that the displacement track, slide and / or drilling / anchor setting unit can be connected to on-board units for the supply of hydraulic medium. This means that, if necessary, no use of additional units is necessary because the track, slide or drilling / Ankersetzeinheit can be connected with respect to the supply of hydraulic medium to the already existing units of the roller charger. For the embodiment of the invention with only one drilling / Ankersetzeinheit is proposed that this has a mechanism that a

Swiveling the drilling / anchor setting unit by about 180 °. In this way, the individual drilling / Ankersetzeinheit can be used on both and / or a continuous displacement track. In this context, it is then necessary to pivot the drilling / Ankersetzeinheit, which is why such a mechanism is appropriate.

A further advantageous embodiment of the invention provides that the carriage of the drilling / Ankersetzeinheit is connected via an adjustable length drill arm with the carriage. In this way, ultimately, a drivable in three respects extendable or telescopic drilling / Ankersetzeinheit and thus a particularly advantageous kinematics, through which a Maximum range is given for the drilling / Ankersetzeinheit or Ankersetzen. As a first measure, the sliding track is variable in length. On this, in addition, the carriage is installed in a second measure, over which the drilling / Ankersetzeinheit can be moved on the sliding track. Finally, in a third measure, the drill arm is additionally adjustable in its length.

In particular, it is thought that the drill arm is telescopic.

The invention also relates to a drilling / Ankersetzeinheit for installation on a roller charger for use in mining, with a frame having the end of mining rollers and serves to accommodate at least one such Bohr- / Ankersetzeinheit. This drilling / Ankersetzeinheit is arranged movable on the frame of the roller charger, with end positions of the drilling

Anchoring unit in the form of a parking position within the contours of the frame and a maximum working position outside the contours of the frame and beyond the mining rollers. The invention is characterized in particular by the fact that a

Roller charger is created for use in mining, which is the

Anchor netting significantly improves and makes it safer. This is the

Roll loader according to the invention per se equipped with at least one drill / Ankersetzeinheit, this is adjustable between a parking position and an arbitrarily large number of working positions and must therefore not be retrofitted in case of need drilling / Ankersetzen. Thanks to a particularly advantageous kinematics around one in the maximum case up to three times

Telecopability of the drilling / Ankersetzeinheit, whose range is particularly large. Serve for this purpose, a carriage on which the drilling / Ankersetzeinheit is movable and / or an adjustability of the installed on the frame of the loader track and / or the telescoping of the drill arm between the carriage and carriage. This makes it possible, above all, to edit the rock as well clearly outside the contours of the frame of the shearer, in any case beyond the rollers. For this purpose, the boring / anchor setting unit can be moved as such and pivoted practically as desired beyond the rolls. This is a backup of the mountains in the sensitive area beyond the roller up to the distance possible.

Further details and advantages of the subject invention will become apparent from the following description of the accompanying drawings in which a preferred embodiment with the necessary details and individual parts is shown. Show it:

Lying. 1 shows an inventive roller charger 1, with the frame 4 and the two removal rollers 5 and 6 at its end faces 24 and 25. On the frame 4 in this embodiment, two drilling / anchor setting units 2, 3 are positioned, of which the drilling / Ankersetzeinheit 2 is located in a parking position within the contours of the frame 4, in which it saves space as possible and the work of the mining roller 6 is accommodated in any way limiting. The drilling / Ankersetzeinheit 3 (and in a modification 3 '), however, is located in one of the working positions. The units 2, 3 each comprise a carriage 10, 11, by which they are movable on the respective

Moving track 7, 8 are arranged. They also include carriages 13, 14 with a movable drill drive. About drilling arms 15, 16, the orientation of the carriages 13, 14 is carried out by the reference numerals 26 and 27 hydraulic units are designated for power supply. With the reference numerals 28 and 29, 30 are

Energy guiding chains called. Particular attention in the illustration according to FIG. 1 lies on the carriages 14, 14 'shown on the left side, which are positioned vertically here and for the purpose of illustrating two

different positions of this carriage 14, 14 'serve with their drilling / Ankersetzeinheit 3, 3'. This is intended to illustrate the particular scope that brings the roller charger according to the invention 1 together with drilling / Ankersetzeinheiten 2, 3, 3 'with it. Thus, in the maximum working position shown here, which corresponds to the position of the carriage 14 ', it is possible, far beyond the roller 5, in this case with upwardly directed carriage 14', to work the hanging wall by drilling or anchoring. In Figure 2, the roller charger 1 is shown in plan view. To recognize here are well the moving tracks 7, 8 for the drilling / Ankersetzeinheiten 2, 3 with the carriage 10, 11, which are each arranged here in an extended position to the left (carriage 11) and to the right (carriage 10). The

Moving tracks 7, 8 are arranged one behind the other in the common axis 12. Here, too, it is clearly recognizable that the drill holes shown on the left

/ Ankersetzeinheit 3 together with carriage 14, 14 'beyond the removal roller 5 and the carriage 13 is in a parked position. A modification of this show the figures 3 and 4. Thus, Figure 3 again shows the drilling / Ankersetzeinheit 2 shown on the right in a parking position and the drilling / Ankersetzeinheit 3 shown on the left in a maximum

Working position with extended carriage 11 and a carriage 14, the in

Compared to the illustration in Figure 2 was pivoted by approximately 90 °.

It is intended to illustrate that thanks to the maximum working position of this carriage beyond the removal roller 5 there, a practically unrestricted pivoting of the carriage 14 is possible. This is especially true when - as shown here - the carriage 11 and the sliding track 8 in the

extended position are located while also on the drill arm 16, the carriage 14 is also maximally extended.

FIGS. 5, 6 and 7 serve above all to illustrate the mentioned, maximum three-fold adjustability of the drill-anchor setting units 2, 3, which is decisive for the flexibility of the invention

Roller charger 1 contributes. In the illustration according to FIG. 5, both drilling and anchor setting units 2, 3 together with respective carriages 13, 14 are in parking position, ie on the frame 4 within its contours and thus as far inside as possible and with retracted downwards, parallel to the axis 33 of the frame positioned carriages 13, 14th

The drilling / Ankersetzeinheit 2 is now moved in the illustration of Figure 6 to the right in the direction of removal roller 6. More precisely, the carriage 10 together with carriage 13 was moved on the displacement track 7 as far as the frontal end 24 of the frame 4 as possible. The sliding track 7, however, is still in the retracted position. Even in this positioning, however, it is easy to see how far the carriage 13 has already extended. This then applies even more for the representation according to Figure 7, in which not only the carriage 10, but also the sliding track 7 in the maximum is in the extended position. Thus, the carriage 13 now extends well beyond the removal roller 6 addition.

Illustrated in Figure 8, the drilling / Ankersetzeinheit 2, consisting essentially of the aggregates carriage 10, drill arm 15, carriage 13 and drill drive 20. The reference numeral 7 denotes the sliding track on which the carriage 10 is movable. Between the carriage 10 and the carriage 13 of the drill drive including hydraulic cylinder 23 is provided, via which a pivoting and / or extension of the carriage 13 about the transverse axis 30 and the longitudinal axis 31 is possible. On the other side of the drill arm 15 is the carriage 13 with the drill drive 20 which is arranged movable on the latter. The middle drill steel guide 22 and the front drill steel guide 21 serve to guide the drill string, not shown here. Figures 9 to 12 serve to additionally illustrate the

Functions of the roller charger with two drilling / Ankersetzeinheiten 2.3.

In particular, it should be shown how well and easily the carriage 14 can be used. For this purpose, it is first shown in the illustration of Figure 9 in the park position on or above the frame 4 of the roller charger.

Carriage 14 such as drill pipe 32 are here parallel to the axis 33 of the frame 4. The removal roller 5 can be used completely unaffected or unimpaired by the carriage 14 - and vice versa.

In the illustration according to FIG. 10, the carriage 11 is in the extended position on the sliding track 8. The carriage 14 together

Drill pipe 32 is swung relative to the drill arm 16 in approximately horizontal position at the impact anchoring hanging end.

The situation is similar with the representation according to FIG. 11. Also there, the carriage 11 is in the extended position. In addition, this applies to the sliding track 8. The carriage 14 is now positioned perpendicular to the shock anchor ridge, so that a drilling or Ankersetzen performed in the hanging wall can be. Illustrated by the axis 34 of the carriage 14 and the axis 35 of the drill roller 5, as far as the drilling / Ankersetzeinheit 3 can operate beyond the mining roller 5 in unhindered form. Finally, Figure 12 shows this also for drilling or Ankersetzen in

Close to the ground at the impact anchorage lying and a correspondingly positioned carriage 14 with downwardly pivoted drill arm 16.
