and rear device, optionally with the interposition of joints or crank-like swivel arms, so to one Couple to couple that the frame with mutual support and led to each other moved in succession can be, whereby the lame at the same time adjust independently of each other to unevenness of the lying can (DAS 1 097 932 and DAS 1 202 238).

It is also known to use extension members, such as extension blocks or extension spans, for bracing and anchoring at the same time to use a face conveyor in inclined storage, which in turn is used to guide a mining machine, such as e.g. a planer or a cutting machine (DAS 1 817 054-, DOS 2 146 811). For bracing the face conveyor are arranged on the offset side of the clamping cylinder, which is connected to the conveyor via an intermediate harness are connected and are supported on the extension members. The clamping cylinders are supported e.g. on clamping beams, which are guided displaceably in a telescopic guide of the external component.

For short front operations, especially for driving up Machine sheds, jacking devices are also known, in which the tunneling machine is attached to a movable machine guide, which in turn has movable extension members is connected, is guided along the joint. In a known device of this type are to anchor the Machine guide anchoring brackets provided, each

consist of two frames connected to form a team (DBP 1 158 929). One of the two frames is connected to the machine guide to form a movable unit while the other frame is coupled to the first-mentioned frame via a rear cylinder in such a way that the two frames taking the machine guidance along in succession can be moved.

Finally, it is also known to use special lifting and control units for controlling the cutting horizon of a mining machine. Provide control cylinders with which the machine guidance can be tilted in the vertical plane (DAS 1 219 892). The control cylinders are supported on movable ones Expanding members from while they are articulated with their piston rods en the machine guide that they are around to pivot a connection joint arranged on the expansion capital.

The invention relates in particular to an anchoring bracket for anchoring the machine guide of a short one Shock-working tunneling or mining machine, as they are mainly used for driving machine stalls or is used by rivers and the like. Object of the invention it is primarily to create an anchoring bracket, which is particularly advantageous as an integral part a jacking device or its machine guidance can be used and with which a particularly reliable and stable anchoring of the machine guide is possible when

50981 1 / OU?

can achieve equally good guidance of the parts in the reverse direction, especially in inclined storage. The machine control should and those joined together to form the anchoring trestle, preferably consisting of extension frames Extension members can adjust independently of each other to unevenness of the hanging and lying walls. Important is here that the bracing and anchoring of the machine guide is reliable even during the back of the extension members preserved. Finally, the machine guide should preferably also be adjustable in height for the purpose of Control of the cutting horizon of the tunneling or mining machine should be possible.

The anchoring bracket according to the invention is characterized in that both extension members of the anchoring bracket each have a guy beam guided on their lying sleeper, and that the guy beams of the two extension members at the end connected to a common yoke via a hinge connection with a horizontal hinge axis are, which in turn is articulated with the machine guide.

The articulated connection between the guy beams and the yoke preferably consists of a parallel link system with horizontal joint axes. With such an articulated coupling, the expansion members and the machine guide largely independently of each other on unevenness of the lying surface without affecting the parallel

50981 1 / 0U7

leadership of the extension members or the leadership of the guy beams on the extension members is in question. Because both Extension members of the anchoring trestle each have a bracing beam, the result is a stable anchoring of the Machine guidance and at the same time good guidance of the extension members and the machine guidance during the back. It It is advisable to assign a separate rear cylinder to each bracing beam of the two extension members, which is in the as Hollow beams can be accommodated in a space-saving and protected manner, the guy beam is expediently guided displaceably in telescopic guides of the sleepers of the extension members. With the back the machine guide, both back cylinders are acted upon in the reverse direction, so that over both guy bars of the Anchoring block the machine guide is advanced. Here, both extension links are coupled to form a team of the anchoring trestle braced between the hanging wall and the lying, so that the anchoring even with stronger collapse and tensioning of the machine guidance is guaranteed during the reverse process. After the back of the machine guide the extension members of the anchoring bracket can be made up individually, whereby the braced one in each case Extension member takes over the leadership of the extension member in the back and the anchoring of the machine guidance .

According to a further feature of the invention, that is the guy beams connecting yoke via a ball joint with the

50981 1 / 0U7

Machine guide or an attachment of the same connected. In this way, the coupled via the yoke can Adjust parts largely independently of one another for unevenness in the lying position. At the same time, it offers spherical or Cardan joint the possibility of the machine guidance in the horizontal plane or in the seam plane with the help of the rear cylinder xu, e.g. to face the machine guide align the mining face or the mining face according to the desired course of the route or the like. to pan.

According to a further feature of the invention, the yoke is connected to a guide member which is attached to the machine guide Is guided longitudinally. The guide member preferably consists of a guide bar, the Advantageously, the length is at least approximately equal to Width of the anchoring bracket is. It is recommended that the guide link or the guide bar have a T-slot on the machine guidance. This arrangement makes it possible to have the connection point of the anchoring bracket opposite to move the machine guide in its longitudinal direction. It is advisable to arrange the arrangement in such a way that that the guide member or the guide bar can be fixed relative to the machine guide, which e.g. by means of a clamping cylinder or the like. can be reached. With the guide member or the guide bar is preferably at least a clamping cylinder connected, which in turn is attached to the

50981 1 / 0U7

Machine guidance or an attachment of the same connected is and with which the entire machine guide braces in the longitudinal direction or in the direction of the collapse and / or the guide member or the guide bar can be adjusted in the longitudinal direction relative to the machine guide.

About a height control of the machine guidance and thus a control of the cutting horizon of the tunneling or mining machine to achieve, can be between the machine guide and the guy beam or one connected to it Part of at least one control cylinder pivoting the machine guide in the vertical plane can be arranged. Preferably the arrangement is made in such a way that the bracing beams each have a protruding console in the front area, on which a control cylinder articulated to the guide member or its piston rod engages. The control cylinders are located in an approximately horizontal position directly above that connecting the guy bars with the yoke Parallel steering system.

According to a further feature of the invention, they are parallel lying sleepers of the anchoring brackets forming the anchoring trestle, which are led to one another, in the vertical plane against one another adjustable to allow extensive adaptation of the extension links to unevenness in the hanging wall and lying on the floor to reach. In this case, an arrangement is particularly useful in which at the lying threshold of one extension member according to the invention a vertical guide is arranged,

50981 1 / 0U7

in which a sliding block can be moved vertically and transversely but the axis running backwards is rotatably guided. The sliding block is at the same time on a parallel guide running in the rearward direction, the lying threshold of the other Extension member led. In this way, an exact parallel guidance is achieved with relatively simple means of the expansion members, but they perform pivoting or sliding movements against each other in the vertical plane can. Said vertical guide preferably consists of a T-slot guide. The sliding block points here a round slider designed in the manner of a pivot pin, vertically movable and rotatable in this groove on, which is integrally connected to a guide piece via a tapered neck piece, one of which is the parallel guide forming, preferably tubular, guide rail engages. TJm to guide the extension members of the anchoring trestle above the lying sleepers and To keep parallel spacing, it is advisable to use a parallelogram lever system with vertical joint axes to switch on the parallel guide, this parallelogram lever system with a diagonally arranged straightening cylinder for aligning the extension links.

The machine guidance expediently has a driving cylinder box that holds the driving cylinder of the driving or mining machine receives and with which the anchoring bracket is coupled in the manner mentioned. The driving cylinder can

The one in the Pig. The jacking device shown in 1 and 2 is preferably used to drive machine stalls, Seam stretches and for use in other short front operations. Hit 10 is the excavation face, 11 denotes the hanging wall and 12 denotes the horizontal wall. The jacking resp. The basic structure of the mining machine is known per se. It has two cylindrical ones on a boom 13 or slightly conical cutting drums 14 and 14 'equipped with cutting tools (not shown) and revolve around horizontal axes running parallel to the joint 10. The boom 13 with the cutting drums is on a machine frame 15 around a joint 16 with horizontal The pivot axis can be pivoted so that the cutting drums, as in Pig. 1 indicated, from the lying 12 to the hanging wall 11 can be pivoted back and forth. The machine frame 15 is mounted on by means of skids 17 and 18 a machine guide M in the direction of arrow S along the working face. The machine guide M consists essentially from a guide bar resting on the lying 12 19 «of the abutting side a ramp 20 and above the same has a guide rail 21 on which the machine frame of the tunneling or mining machine with their front guide shoes 17 is performed. A cylinder box 22 is connected to the guide bar 19 on the offset side, which carries a guide rail 23 on its upper side, on which the guide shoes 18 are guided. The driving cylinder box can drive the propulsion basw. Ge

record recovery machine. The drive is there expediently from a (not shown) arranged in the cylinder box 22, relatively long-stroke Driving cylinder, the lifting movements of which can be transmitted to the machine frame 15 via traction means. The traction means are anchored on the one hand to the machine frame and on the other hand to the cylinder box and over Openings led out of the cylinder box.

That from the tunneling or mining machine at joint 10 When the machine guide M is bent in the reverse direction E over the ramp 20, the loosened material is transferred to the guide bar postponed, which forms or receives a conveyor trough in which the goods are conveyed to a transfer point. With sufficient collapse, the goods slide in by themselves down the slide. However, there is also the possibility of a conveyor, e.g. a chain scraper conveyor, on the beam 19 conventional type to be arranged, which removes the good.

For bracing and anchoring the machine guide M are arranged on the rear side at intervals a plurality of anchoring brackets A, the following in particular in connection 3 to 6 are explained in more detail.

Each anchoring bracket consists of two coupled, frame-like extension members I and II, each two hydraulic ones standing one behind the other in the reverse direction R

50981 1/014 7

Have stamps 24 and 25 or 24 'and 25', which with their feet 26 (FIG. 3) supported on a lying sleeper 27 or 27 '. The lying sleepers are pot-shaped Attachments 28 on, in which the stamp with their feet are held. The stamps of each expansion member wear multi-part caps 29 on their heads, which over a Intermediate member 30 are connected to one another.

The two sleepers 27, 27 'each have one in its longitudinal direction extending guide opening in which a guy beam 32 is guided. The two As is known, guy beams are designed as Eohl beams} they each take on a rear cylinder 33, the piston rod 34 of which via a hinge pin 35 at the rear end the lying threshold or the telescopic guide is supported. The rear cylinders 33 are each in the front area connected to the guy beams via a joint 36. Will the rear cylinder 33 is acted upon in the extension direction, the guy beams 32 are accordingly in the rear direction R pushed out to the machine guide M, with the Support the piston rods 34 of the rear cylinders on the sleepers.

At the front end protruding from the guide opening 31 the suspension beam 32 is in each case an upwardly protruding, fork-shaped console 37 attached via a parallel link system is connected to a common yoke 38. The two Farallellenker systems each consist of two

50981 1 / 0U7

Pairs of parallel links 39 and 40 arranged one above the other, which have joints 41 to 44 with horizontal joint axes with the consoles 37 and the yoke 38 are connected. The two bracing beams 32 of the extension members I and II are thus articulated on the common yoke in the tertiary plane 38 connected so that the Auebauglieder can adjust independently of each other on unevenness of the recumbent. On the yoke 38, a joint ball 45 is arranged centrally between the parallel link systems, which by means of a Plug pin 46 is attached to the yoke and engages in a bearing shell of a guide bar 47. The joint ball is tensile, but articulated on all sides with the guide bar 47 connected. The machine guide M has on its rear side a T-slot guide 48 in which the guide bar 47 middle »a correspondingly profiled projection 49 in the longitudinal direction of the machine guide (arrow S) is slidably guided. To the guide bar 47, the length of which corresponds approximately to the total width of the anchoring bracket, to be detachably fixed with respect to the guide 48 and thus with respect to the machine guide M is a special one Locking device is provided, which can for example consist of hydraulic clamping cylinders 50 (Fig. 5).

Above the parallel link systems are double-acting hydraulic control cylinders 51 lying approximately horizontally arranged via joints 52 with on the guide bar 47 arranged upstanding fork consoles 53 connected

509811/0147

are and the piston rods 54 are articulated at 55 on the brackets 37 of the two guy beams. Vie in particular Pig. 5 shows, a separate control cylinder 51 is assigned to each extension member. The connecting joints 52 and 55 can be designed as cardan joints. It can be seen that when the control cylinder 51 is pressurized in the insertion direction, the machine guide M with its ramp 20 is pivoted upwards towards the hanging wall, while the control cylinder is operated in the opposite direction the machine guide is pivoted in the opposite direction. In this way, the cutting height adjust the heading or mining machine.

A clamping cylinder 57 is connected to the Jührungsbalken 47 via a joint 56, the piston rod 58 of which is at 59 is hinged to the rear of the machine guide or the Ifahrzylinderkasten 22. With the help of the individual anchoring sböcken associated clamping cylinder 57, which is in the ? ig. 1 and 2 are omitted, the entire machine guide can be braced against the collapse, like this is known per se in the tensioning of face conveyors. In addition, with the aid of the tensioning cylinder 57, the guide bar 47 can be moved in the direction of arrow S in relation to the machine guide are adjusted after previously the locking by the clamping cylinder 50 or the like. has been repealed. This enables the connection points of the individual anchoring brackets to be offset on the machine guide.

The two frame-like extension members I and II are led to one another with their sleepers 27 and 27 *. Here, the threshold Lying 27 'of the expansion member I at its iusbauglied the side facing II tubular guide rail 60 (Fig. 5) on a sliding block _r leads of the 61. This sliding block has a round sliding piece 62 designed in the manner of a pivot pin, which is connected in one piece via a tapered neck piece 63 and an intermediate piece 64 to a guide piece 65 which surrounds the guide rail 60 in a claw-like manner. The slider 62 is guided in a vertical guide 66 of the extension member II so as to be displaceable in the vertical direction and at the same time rotatable about its axis 67. According to FIG. 1, the vertical guide consists of a T-slot guide which engages around the slider 62 in a form-fitting manner. From Fig. 5 it can be seen that when the extension member II is bent in the stooping direction B, the sliding block 61 guides itself on the guide rail 60 so that the extension member II is displaced parallel to the extension member I. The extension member II can perform movements in the vertical plane due to the vertical guide 66, so that the extension members can adjust independently of one another while maintaining their parallel guidance on unevenness of the lying person.

Above the lying sleepers 27, 27 ', a further parallel guide 70 is switched on between the two outer members I and II (FIGS. 1 and 2), which is provided with a parallelogram link system 72, whose joints

50981 1 / 0U7

with vertical hinge axes connected to a scissor-like handlebar Form trained spacer for the distance adjustment of the two expansion members. Between the handlebars iet a straightening cylinder 71 switched diagonally, with the the parallelogram link system is more or less spread and thus the distance between the extension links can be adjusted. The parallelogram link system is, as Fig. 1 shows, via pipe clamps 75 nri.t the lower rams the hydraulic rams 24 and 25 of the extension member II vertically adjustable connected, it is provided with a guide member 74- which on a longitudinal guide of the other expansion member I is guided and by applying pressure to the straightening cylinder 71 transversely to the reverse direction can be adjusted.

To the machine guidance M with the tunneling or mining machine To advance in the reverse direction R, the rear cylinder 33 of the "two extension members I and II of the anchorage Sbocks A acted upon in the extension direction, so that the guy beams 32 slide out together and thereby the Machine guide M via the parallel link systems and the yoke 38 and the guide bar 47 to push 10 towards the joint. during this process are the two expansion links »Between hanging and lying, tense. The two expansion elements are then made up individually. To this The purpose is first of all the stamps 24 and 25 of the extension member II relieved, whereupon this expansion member

509811/0 147

associated rear cylinder 33 is applied in the insertion direction is so that the expansion member II, on the braced expansion member I is pushed over his guy bar. During this process, the expansion member I alone takes over the Bracing and anchoring of the machine guide M. Nach The expansion link then becomes re-tensioning of the expansion link II I relieved and also made up for it.
