    The invention relates to a device for removing material excavated underground within a distance ascended, in particular, by the room-and-pill method, comprising a belt conveyor having an endless conveyor belt, which has a conveyor section that can be extended continuously along a conveying path according to the progress of the removal.
    In chamber-pillar construction, the so-called room-and-pillar method, a main line, the width of which essentially corresponds to the width of the section-boring machine, is first driven forward ("Development"). Thereafter, the degradation of the main line starting laterally to the formation of chambers ("Retreat Mining"). During the retreat mining phase, the cavities are not supported by internals. Rather, the material is degraded from chambers, and it will be left pillars of rock or coal to support the ridges.
    The removal of the mined material can take place both during development and during the retreat mining with the aid of a belt conveyor. The conveyor belt can be guided to just behind the mining equipment and must therefore be continuously extended or replicated according to the progress of dismantling. In order to avoid interruptions of Abförderbetriebs for the extension of the endless conveyor belt, conveyor belt storage have become known that store the conveyor belt in multiple deflected, compressed state and from which a conveyor belt reserve can be pulled out. Various options have already been proposed for the extension of the support frame for the conveyor belt. 2/35 ···························································································· ············································································································································································ In WO 2008/031125 A2, a transfer trolley for taking over coming from the mining equipment, mined material and a tape storage is described, in the transfer trolley a plurality of support elements is kept in stock. With continuous removal of the tape removal takes place from the tape storage and the individual support elements are removed from the transfer trolley and brought into the working position on the sole. A disadvantage of this design is that the storage capacity of support elements in the transfer trolley limits the maximum extent of continuous extension.
    From DE 3837986 Al a support frame for a belt conveyor has become known, which consists of a plurality of telescopically displaceable support elements, so that the support frame can be pulled apart to allow an extension of the conveyor line. The individual support elements are supported by runners on the sole. Again, the extension of the conveyor line is limited, wherein the limiting factor is the maximum extendibility of the support frame.
    In the discharge system described in US Pat. No. 5,246,274, the extension of the conveying path is achieved by introducing movable conveyor belt weighing into the conveying path. In this system, the extension of the conveyor line is limited only by the number of available conveyor belts and, as always, by the available tape reserve of the tape storage. However, there is the disadvantage that the conveyor belt weighers are introduced at the end of the conveyor line, so that at any time the entire chain of conveyor belt weighing behind the excavator 3/35 must be tightened, which requires complex Nachziehvorrichtungen.
    The invention therefore aims to form a discharge device such that an uninterrupted discharge during a conveyor line extension, but also during a deconstruction of the extension succeeds. Furthermore, the discharge device should be usable both for the phase of development and for the phase of retreat mining. Furthermore, the extent of the conveyor extension should only be limited by the band reserve of the band memory and by no further limiting factors. Furthermore, the extension elements of the conveyor belt support should be as versatile as possible.
    To solve this problem, the invention provides a device for conveying away material degraded underground in a particular ascended by the Room-and-Pillar method before route, which comprises a belt conveyor having an endless conveyor belt, which has a according to the mining progress continuously along a conveyor section extendable conveyor section wherein the belt conveyor in the conveying section comprises at least a first, movable in the longitudinal direction of the conveyor track supporting device for the endless conveyor belt and a plurality of coupled, movable in the longitudinal direction of the conveyor track conveyor belts, each supporting elements for the endless conveyor belt, and wherein between the first support device and the plurality of conveyor belt weighing a second movable support device for the endless conveyor belt is arranged, which is coupled to the first support device and * · • · • * ··· ·····························································································································································································································································································································································
    The discharge device according to the invention thus comprises at least three successively arranged segments of the endless conveyor belt supporting support. The first movable support device is the first in the transport direction, arranged behind the excavator support, in which segment the material is taken either directly from the mining equipment or from a buffer for mined material. To the first movable support device, the second movable support device is coupled, which forms the second segment of the conveyor belt support. The third segment is formed by the plurality of movable conveyor carriages coupled to each other, which are decoupled from the second support device. However, the conveyor belt trolleys are guided in mutually coupled movable guide frame elements, wherein the adjoining the second support device guide frame element can be coupled to this. For the extension of the conveyor line additional movable conveyor weighers are now not coupled at the end of the conveyor line, but on the second segment forming the second support device, which comprises guide means for introducing the conveyor belt weighing in the conveying path from a arranged next to the conveyor line position. The conveyor weighers are in the direction of 5/35
    • • • ♦ • * ♦ t •% · 1 • · ·· > · I s introduced to the third segment, namely to the guide frame elements. In order to facilitate insertion, the procedure is preferably such that the upper run of the endless conveyor belt is guided in an elevated manner in the region of the second support device. Preferably, the second support device is designed as a movable frame element. Due to the central introduction of new conveyor weighing in the conveyor line an uninterrupted extension of the belt support is made possible. In addition, in such an embodiment, only the first and the second support device must be tracked together with the guide frame elements the mining equipment, with the possibly large number of belt weighers can remain in their respective position.
    If the conveyor belt weighers are unchangeable in length, the conveyor belt weighers can usually only be introduced individually into the conveyor line, with the introduction of a single conveyor belt carriage must be maintained until a sufficient gap between the second support device and the nearest, in the Conveyor belt arranged conveyor belt remains. However, if, as is the case with a preferred development, the conveyor belt trolleys are designed to be expandable and compressible in the longitudinal direction of the conveyor section, a plurality of conveyor belt trolleys can be introduced jointly into the conveyor line. The conveyor belt weighing in this case preferably comprise at least two, preferably three frame members which are telescopically guided into each other. In this case, the procedure is preferably such that a plurality of belt conveyors coupled to one another are introduced into the conveying section in the compressed state. 6/35
    Thereafter, the foremost conveyor belt car, i. the one conveyor belt carriage which is closest to the second support device is connected to a guide frame element. As a result, the foremost conveyor belt trolley, together with the second support device and the guide frame elements, is entrained behind the dismantling device when the first support device retracts, wherein the conveyor belt trolleys are continuously pulled apart. Only when the extraction reserve of all recently introduced in the conveyor belt conveyor belt is exhausted, it is necessary to re-introduce conveyor belt weighing in the track. For the insertion process, the conveyor belt carriage which is located in the last guide frame element, i. in the guide frame member, which is the farthest from the second support device, fixedly connected to this guide frame member. The result of this is that the separated conveyor belt carriages located in the guide frame elements are pushed together or compressed when additional conveyor belt carriages are inserted. This results in a total
    Accordion effect, which means that a large number of belt conveyors can be introduced simultaneously into the conveyor line without interrupting the conveying process.
    In order to prevent lateral deflection of the conveyor belt carriages arranged in the conveying path during the introduction of further conveyor belt weighing while compressing the conveyor belt carriages already arranged in the conveying path, the guide frame elements are provided. These are in particular designed in such a way that they overlap the conveyor belt carriages arranged in the conveying path in a portal-like manner. The guide frame elements provide in particular a lateral guide on both sides of the conveyor belt weighing available. The guidance of the conveyor belt trolleys in the guide frame elements can preferably be improved in that the guide frame elements have at least one guide element extending in the longitudinal direction of the conveyor line, in particular guide rail on which the conveyor belt trolleys arranged in the conveyor line are movably guided in the longitudinal direction of the conveyor line.
    In order to connect a conveyor belt trolley, as described above, either to the first or the last guide frame element, it is preferably provided that the first and the last guide frame element respectively have locking means for blocking a relative movement of the conveyor belt trolley respectively arranged in the guide frame element relative to the guide frame element.
    The belt conveyors to be introduced into the conveyor line can be kept in stock in a larger number in addition to the conveyor line, wherein a suitable tractor, such as provided with a suitable drive vehicle, each having a plurality of conveyor belt trucks coupled to each other next to the conveyor line to the second Transporting support device. In order to ensure adequate guidance of the conveyor belt trolleys to be introduced during the insertion process, a preferred development provides that the first support device has a guide element running in the longitudinal direction of the conveyor line, in particular guide rail on which the conveyor belt trolleys arranged in the longitudinal direction 8/35
    The conveyor track is movably guided , The conveyor belt carriages to be introduced are thus arranged laterally next to the first support device in the longitudinal direction, i. guided in parallel to the conveyor line and reach in the sequence the guide means of the second support device, which may be preferably designed as a guide rail and in particular S-shaped to lead the conveyor belt weighing similar to a rail switch from the arranged next to the conveyor line position in the conveyor line. The guide means of the second support device may be arranged displaceable or pivotable in this context similar to a rail switch and in this context preferably further developed such that it can be displaced into a position connecting the mutually facing ends of the guide element of the first support device and the guide element of the adjacent guide frame element ,
    The conveyor belt carriages to be introduced into the conveyor line are transported to the insertion point in a compressed state for reasons of space, locking means preferably being provided for locking the compressed state in order to prevent the traction force caused by the tractor from leading to a pulling apart of the conveyor belt carriages.
    As already mentioned, the upper run is raised in the area of the second support device in order to facilitate the lateral introduction of conveyor belt trolleys. The training is in this context preferably further developed such that the upper run of the endless conveyor belt from the first support device to the second support device ramping up and from the second 9/35

    Supporting device is led to the arranged in the conveyor section conveyor belt down ramps descending. While the upper run in the region of the second support device is preferably supported on a plurality of support rollers, the lower run is preferably designed to be freely suspended, in order to enable the lateral introduction of the conveyor belt trolleys. Care must be taken when inserting the belt trolleys sideways to ensure that there is sufficient vertical distance between the upper runner support and the lower runner support elements attached to the conveyor belt trolleys to facilitate threading the lower run between the upper and lower support members. The training is in this context further developed such that the conveyor belt weighing each support elements, in particular rollers or rollers, for the upper run and support elements, in particular rollers or rollers, for the lower run, wherein the support rollers for the upper strand are arranged to pivot upward. An expedient development provides in this context, that the support rollers for the upper strand are automatically pivoted upwards when the conveyor belt carriage is introduced into the conveyor line. This can be realized in an advantageous manner such that the second support device comprises a ramp-like casserole element, with which the support elements for the upper strand when inserting conveyor belt weighing in the conveying path co-operate to effect a upward pivoting of the support elements.
    In principle, the first supporting device can be designed as desired, wherein it is preferably provided that the first supporting device is formed by at least two mutually coupled, movable conveyor belt carriages of fixed length.
    The first support device may, if necessary, have its own drive to allow a corresponding to the dismantling progress of the excavation device required tracking of the discharge device. The first support device pulls the second support device and the guide frame elements behind it, the second support device, the guide frame elements and the conveyor belt trolleys not having their own travel drive.
    Alternatively, the first supporting device does not have its own traction drive, but is coupled to a separate traction unit or the dismantling unit.

    In Fig. 1, a portion of an ascended by the Room-and-Pillar method main line is denoted by 1. From the main line 1, a branch line 2 ("Retreat Mining") leads away at an angle of 90 ° to the working face 3. At the working face 3, a tunneling machine 4 is schematically arranged, wherein the material excavated by the tunneling machine 4 is transported away via a bridge conveyor belt 5. The bridge conveyor belt 5 transfers the excavated material to the removal device according to the invention, which comprises a movable belt deflection station 6 directly behind the bridge conveyor belt 5. In Bandumlenkstation 6, the endless conveyor belt of the discharge device is deflected. The deflecting station 6 is adjoined by a plurality of segments of the discharge device, namely a first supporting device 7, a frame-like second supporting device 8, a plurality of telescoping conveyor belt carriages 9 coupled to one another, which are guided in a plurality of guide frame elements 10. Subsequently, further conveyor belts 11 coupled to one another are arranged, which have a fixed carriage length. The first support device 7, the second support device 8, the conveyor belt trolleys 9 and the conveyor belt trolleys 11 guide the endless conveyor belt to a deflection device 12, in which the endless conveyor belt is deflected by 90 ° into the main section 1. In the main line 1, a conveyor belt storage 13 is arranged. 12/35 · * ··· ♦ · < ········································································································································
    The mined by the tunneling machine 4 material is transferred by the bridge conveyor belt 5 on the Bandumlenkstation 6 and is transported on the endless conveyor belt to a transfer station 14, which transfers the material to a not shown, extending in the main line 1 further discharge device.
    In addition to the conveying path formed by the endless conveyor belt, a plurality of conveyor belt carriages 15 are arranged in the region of the first supporting device 7, which, as will be explained in more detail below, can be introduced into the conveying path. Reference will now be made to FIGS. 2 to 5 as to how the further conveyor belt carriages 15 are introduced into the conveying path. In Fig. 2, the first supporting device for the endless conveyor belt is again denoted by 7 and comprises three mutually coupled movable conveyor carts 16 with a fixed carriage length. The conveyor belt trolleys 16 have supporting elements in the form of supporting rollers for the upper strand and for the lower strand. The upper strand is designated 17 in FIG. 2. The conveyor belt trolleys 16 carry laterally a guide rail 18 which, as will be explained in more detail below, serves to guide the further conveyor belt trolleys 15. The second support device 8, which is designed as a movable frame element for introducing the further conveyor belt trolleys 15, is coupled to the last conveyor belt carriage 16. To the second support device 8, a plurality of guide frame elements 10 is coupled, of which in Fig. 2, only the first guide frame element is shown.
    In Fig. 3, six further conveyor carts 15 are now shown, the side next to the conveyor line in 13/35 • ······················································································ ♦ Ο «• · · ·« · ·
    Direction of the arrow 20 are moved toward the working face. The further conveyor belt carriages 15 are in the compressed state and are coupled to one another. The transport in the direction of the arrow 20 is effected by a pulling device, not shown, which is coupled to the first conveyor belt carriage 15. Upon reaching the guide rail 18 not shown guide elements of the conveyor belt weighing 15 interact with the guide rail 18. The guide elements may for example be U-shaped and engage around the guide rail 18.
    In the state cooperating with the guide rail 18, the conveyor belt carriages 15 are moved further in the direction of the arrow 20 until they assume the position shown in FIG. Thereafter, the S-shaped guide rail 21 of the second support device 8 is pivoted from the position shown in Fig. 3 in the position shown in Fig. 4, so that the further guide belt weighing 15 facing the end of the guide rail 21 is aligned with the guide rail 18.
    Starting from the position shown in FIG. 4, the conveyor belt carriages 15 are subsequently moved in the direction of the arrow 22, wherein the conveyor belt carriages 15 are forcibly guided along the guide rail 18 and then along the guide rail 21 and introduced into the guide track in this manner. The guide frame element 10 adjacent end of the guide rail 21 is aligned with a further guide rail 51 which is arranged in the guide frame elements 10. The conveyor belt trolleys 15 are thus pushed into the guide frame elements 10 until all 14/35 conveyor belt weighing 15 into the conveyor line are introduced. When the further conveyor belt trolleys 15 are introduced into the guide frame elements 10, the conveyor belt trolleys 9 already arranged in the guide frame elements 10 are compressed in the longitudinal direction. Thus, before the introduction of the further conveyor weighers 15 in the compressed state, a total of six conveyor weighers 9 in the extended state in the guide frame elements 10, they are so compressed during insertion of the six other conveyor weighers 15 that thereafter a total of twelve conveyor weighers (six conveyor weighers 9 and six conveyor belt weighing 15) are in the compressed state in the guide frame elements 10.
    In the detailed illustration according to FIG. 6, the state corresponding to FIG. 4 is shown. There are a total of six guide frame elements 10 are arranged, which are coupled together. In the guide frame elements 10 there are a total of six conveyor belt weighing 9 in the extended state. Before the introduction of the further conveyor belt trolleys 15, the first conveyor belt trolley 9 'is secured against displacement within the associated guide frame element 10', whereby the conveyor belt trolley 9 'can not be pushed out of the guide frame element 10'. This is the prerequisite for the conveyor belt weighing 9 can be compressed during insertion of the further conveyor belt weighing 15. The guide frame elements 10 serve to prevent lateral deflection of the conveyor belt 9 during the compression process. The conveyor belt carriages 9 are guided for this purpose on the guide rail 51 arranged in the guide frame elements 15/35 in the longitudinal direction of the conveying path.
    After insertion of the conveyor belt trolleys 15, the blocking of the conveyor belt trolley 9 'in the guide frame element 10' is released. For the purpose of extending the conveyor device, the foremost conveyor belt trolley 9 "is secured against displacement within the foremost guide frame element 10 'so that the conveyor belt trolley 9" is entrained by the guide frame element 10 "in the direction of the arrow 23 when the conveyor devices are moved. The tracking of the conveying device takes place in such a way that the bridge conveyor belt 5 and the deflection station 6 are tracked in the direction of the arrow 23 in accordance with the progress of the excavation of the tunneling machine 4. The deflection station 6 is coupled to the conveyor belt trolleys 16, so that they are pulled along. The conveyor belt trolleys 16 in turn pull the second support device 8 coupled thereto. The second support device 8 in turn pulls the guide frame elements 10 coupled thereto. The foremost guide frame element 10 "takes, as already mentioned, the foremost conveyor belt trolley 9", so that overall there is a continuous pulling apart of all the conveyor belt trolleys 9.
    In Fig. 6 is further seen that the upper run of the conveyor belt 17 is guided increased in the region of the second support device 8, wherein the second support device 8 carries corresponding support rollers for the upper run of the conveyor belt 17. In the region of the first guide frame element 10 '', the upper run of the conveyor belt 17 is guided downwards again, wherein the guide frame element 10 '' also 16/35 ···% · ο · * # · # -4 · * #. · Ϊ6: · , carries corresponding support rollers. Only in the area of the further guide frame elements 10 does the upper run of the conveyor belt 17 come to rest on the support rollers of the conveyor belt carriages 9.
    In Fig. 7, the second support device 8 is shown in detail, and it can be seen that it is a frame-like construction, at the top support rollers 24 are arranged to support the upper strand. No separate support elements are provided for the lower run, so that the lower run sags freely in the area of the second support device 8. The second support device 8 has wheels 25, which enable the method of the support device. Furthermore, the S-shaped guide rail 21 can be seen, along which the further conveyor weighers 15 are introduced into the conveyor line. Furthermore, the second support device 8 has a rod-shaped ramp element 26 which forms an ascending ramp 27 at its front end and a descending ramp 28 at its rear end. As will be explained in more detail below with reference to FIG. 13, the run-up element 26 serves to pivot the support rollers of the conveyor belt trolleys 15 provided for the upper run upwards.
    The conveyor belt trolley is shown in detail in FIG. 8, the illustration equally applying to the conveyor belt trolleys 9 and the further conveyor belt trolleys 15, since these can be designed in the same way. The conveyor belt carriage 9, 15 has a doubly telescopic frame 29, are arranged on the support rollers 30 for the upper run and support rollers 31 for the lower run. Furthermore, the frame 29 carries a lateral protective grille 32. As in Fig. 13 17/35 ····························································································. The supporting rollers 30 for the upper strand are fastened to a frame part 34 mounted so as to be pivotable about the pivoting axis 33, starting from the position shown in FIG. 8 in the direction of the arrow 35 in the position shown in FIG. 13, can be pivoted up. As a result, a free space 36 is created, which serves for the insertion of the conveyor belt weighing in the conveying path the lateral introduction of the lower run of the endless conveyor belt 17. In the downwardly pivoted state (FIG. 8), the support rod 37 of the pivotable frame part 34 rests on the bearing 38 of the lower frame part 39. Furthermore, a guide rail 40 is provided on the pivotable frame part 34, which runs onto the ramp 27 of the casserole bar 26 during insertion of the conveyor belt trolleys into the conveying path, thereby causing an upward pivoting of the pivotable frame part 34. Upon reaching the ramp 28, the frame member 34 pivots back down to the initial state due to gravity.
    In Fig. 8 is further seen that the conveyor belt carriage 9, 15 has two axes 41 and 42 with wheels 43. The axle 41 is designed as a rigid axle, whereas the axle 42 is steerable, for which purpose a de-pixel 44 is provided. In this case, the de-pixel 44 serves for the coupling of conveyor belt carriages 9, 15 arranged one behind the other. Because of the steerable axle 42, the trackability of the conveyor belt carriage chain is guaranteed. When pushing the conveyor belt trolleys 9, 15, however, the first conveyor belt carriage is connected to the tractor by means of the rigid frame 29 attached to the coupling element 45, so that no transverse forces are introduced when moving the conveyor belt weighing. 18/35 ········
    In the side view of FIG. 9 it can be seen that at the bottom of the frame 29, a pawl 46 is fixed, which can cooperate with a counterpart 47 when the conveyor belt carriage 9, 15, as shown in Fig. 11, is in the compressed state , As a result, the compressed state of the conveyor belt trolley 9, 15 can be locked, which is particularly advantageous when transporting the further conveyor belt trolleys 15 within the branch line 2 to the first or second support device (FIG. 3) and when being pushed into the conveyor line.
    In FIGS. 9 and 10, it can further be seen that the frame 29 consists of three telescopically displaceable frame elements 48, 49 and 50, so that the conveyor belt carriage, starting from the exploded state according to FIGS. 9 and 10, is in the compressed state according to FIGS. 11 and 12 can be brought and vice versa. 19/35
