Description

Propulsion or mining machine

The invention relates to a propulsion or extraction machine comprising over the working face movable, arranged on a cantilever arm cutting tools and a movable in the machine longitudinal platform which carries track removal facilities.

Such a propulsion or mining machine has become known from AT 507495 AI.

When securing and dismantling a driven route, various types of securing and extension equipment usually have to be made available, depending on the nature of the rock, in addition to anchor drilling and setting devices, also shotcrete manipulators or devices for manipulating and positioning removal frames or attachment frames . -bows are needed. Conventional jacking or mining machines do not fully meet these requirements because the different types of track removal devices can not be provided simultaneously and conveniently in a space-saving manner. For example, the manipulation or extraction machine has proposed separate manipulation devices for expansion elements, such as, for example, expansion frames or expansion arches. However, the effort for route safety and expansion measures is significantly increased by the provision of separate facilities, which due to the limited space in the developed route difficulties exist to carry out the expansion measures also at a position immediately behind the working face. From AT 502 047 A4 an arranged on a sliding track Ankerbohr- and -Setzeinrichtung is known in which a Rollover the Ankerbohr- and -Setzinrichtung an additional manipulator for lifting and for the assembly of drafting mats is attached. An embodiment of an expansion device with two anchor drilling and setting devices, which are pivotably supported on an anchor platform displaceable in the machine longitudinal direction, is the subject of AT 413230 B.

DE 29 34 625 AI shows a combination of a tunneling machine with expansion facilities, in which a Ausbaumanipulator is set on a sliding track, so that pre-mounted path arches transported along the tunneling machine and can be positioned in the front of the tunneling machine in the track.

In contrast, in the subject of DE 34 13 261 AI a fixed at the rear of the tunneling machine slewing crane for receiving the preassembled Ausbaubögen and for the transfer of a movable on the sliding track Ausbaumanipulators in use.

Another example of a movable on a sliding extension scanner can be found in DE 29 08 452 AI.

The described embodiments thus relate, on the one hand, to the provision of individual Streckenausbauein- directions in conjunction with a tunneling machine, although indeed a certain step in the context of the route structure mechanized and can be made efficient, manual operations but still required are. On the other hand, the described embodiments relate to multifunctional solutions (eg AT 507495 AI), which can be used in many ways, but in individual cases adaptation measures are required that complicate a mechanized operation.

The invention therefore aims to further develop a tunneling machine with integrated roadside equipment in such a way that the degree of mechanization for a combined roadway upgrade can be significantly increased. At the same time the individual expansion devices should be placeable on the tunneling machine, that the lowest possible height is achieved. To solve this problem, the invention essentially provides that the track removal devices comprise a Ausbaumanipulator and Ankerbohr- and -Setzeinrichtung, the Ankerbohr- and -Setzeinrichtung between a parking position and an operating position is pivotally mounted on the movable platform and the Ausbaumanipulator a telescopic and in the height direction pivotally mounted on the movable platform arm having a gripping device for temporarily receiving at least one expansion element, in particular Ausbaubogens carries, the Ausbaumanipulator and Ankerbohr- and -Setzeinrichtung are fixed in a predetermined fixed distance from each other on the movable platform and are displaceable together with the movable platform between a retracted and a forward shifted position.

In a further embodiment of this invention, it is essentially provided that the route equipment The anchor drilling and setting device is pivotably mounted between a parking position and an operating position on the movable platform and the support means is a telescopic and pivotable in the height direction at the movable arm mounted platform, wherein the support means and the Ankerbohr- and -setze- device are fixed at a predetermined, fixed distance from each other on the movable platform and are displaceable together with the movable platform between a retracted and a forward shifted position. Characterized in that the Ankerbohr- and -Setzeinrichtung between a parking position and an operating position is pivotally mounted on the platform, the Ankerbohr- and -Setzeinrichtung can be stored to save space during the route propulsion, without hindering the cutting process. In the park position, the anchor drilling and setting device is preferably in a folded flat on the movable platform state. The fact that the Ausbaumanipulator or the support means has a telescoping and pivotally mounted in the height direction of the movable platform arm, the Ausbaumanipulator or the support device for the route propulsion can be swung down to the movable platform, thereby minimizing space consumption. According to the invention, the telescopically movable and vertically pivotable arm of the expansion manipulator has a gripping device with which the individual segments or already screwed multiple segments of the expansion elements, in particular expansion arches, are picked up and brought into the installed position. Due to the pivotable and telescopically extensible construction of the arm, an accurate positioning of the gripping device together with the temporarily received in the gripping device expansion element, in particular the expansion arch, allows. After the gripping device has brought the at least one expansion element to the intended position, the assembly of the expansion element is usually carried out from bottom to top, initially provided the punch and the expansion arch is connected via spacer iron with the previous expansion bow.

The fact that the Ausbaumanipulator or the support means and Ankerbohr- and -Setzeinrichtung are fixed at a predetermined fixed distance from each other on the movable platform, eliminating the need for adjustment of the mutual position of the two expansion devices, so that the handling is simplified and the mechanization can be improved can. The operating position of the anchor drilling and setting device relative to the expansion armature is particularly chosen such that anchors can be set in the region of the vertical plane defined by the expansion element positioned by the gripping device. In the case of the support device, the operating position of the anchor drilling and setting device relative to the support device is selected so that anchors can be set in the region of the ridges supported by the support device.

In this case, a preferred development provides that the support device has a support plate that can be pressed against the ridges.

A preferred development provides in this case that the operating position is selected so that the anchor drilling and setting means and the support means in the operating position in an area of the ridges located in front of the cutting tools act. The mechanization of the track construction can be further improved by the fact that, as corresponds to a preferred development, the track construction facilities further comprise a lifting crane having a rotatable about a horizontal axis of rotation, telescopic boom. In this case, the lifting crane is preferably fastened to the movable platform at a predetermined fixed distance from the expansion manipulator or the support device. Overall, the movable platform thus carries all essential Streckenausbaueinrichtun- required for the track extension conditions, namely the lifting crane, the Ausbaumanipulator or the support device and the Ankerbohr- and -Setzeinrichtung. The route construction is preferably carried out in such a way that in the retracted position of the platform the lifting crane firstly picks up at least one line removal element, lifts it up, carries it forward by pivoting the crane jib and places it in a holding device of the gripping device of the extension manipulator. Thereafter, the movable platform is moved forward and pressed the at least one expansion element by means of the telescopic arm of Ausbaumanipulators to the ridges.

A preferred development provides in this case that the gripping device comprises at least one, preferably two receiving pockets for each one expansion element, in particular a removal arc. In the case of an embodiment with two receiving pockets, two expansion elements, in particular expansion arches, can thus be brought into the installation positions at the same time, so that the speed of the route expansion is achieved. can be increased. Furthermore, the desired distance between two successive expansion elements is predetermined by the distance between the two receiving pockets at the same time. If, as corresponds to a further preferred embodiment, the gripping device comprises a particular bow-like support means for temporarily receiving a default mat, a default mat can be positioned simultaneously with the pressing of the gripping device or the expansion elements to the ridge, so immediately after setting the anchor can be started.

In order to increase the stability of the platform, it is preferably provided that the platform is supported in the forwardly displaced position on a support arranged on the cantilever arm.

The pivoting of the Ankerbohr- and -Setzeinrichtung see the parking and the operating position and the required for the setting of anchors in the entire route profile degree of freedom are structurally particularly simple achieved in that a pivoting device for pivoting the Ankerbohr- and -Setzeinrichtung between the Parking position and the operating position is provided, on which a rollover is arranged, by means of which the Ankerbohr- and -set device is pivotable in the operating position about an axis of rotation extending in the machine axis of rotation. It is particularly advantageous if the pivoting device is arranged at the front end of the movable platform. This makes it possible to move the rollover or the anchor drilling and setting device down beyond the front end of the movable platform and into the loading area. pivoting operating position, so that the most central positioning of Ankerbohr- and -Setzinrichtung is achieved within the route profile. To stabilize the Ankerbohr- and -Setzeinrichtung during the drilling process and during the setting of anchors, the training is preferably further developed such that the pivoting means has at least one in the operating position of Ankerbohr- and -Setzeinrichtung extendable against the sole support punch.

In order to facilitate the operation of the anchor drilling and setting device by operating personnel, it is preferably provided that work platforms are arranged on the movable platform on both sides of the machine longitudinal center plane. In particular, the working platforms can each be lowered and raised relative to the movable platform by means of a lowering and lifting device. With regard to the forces acting on the track removal devices when upgrading the track, a particularly stable guidance of the platform is advantageous. This is achieved in accordance with a preferred development in that the movable platform is enclosed on both sides by guide rails arranged on a machine frame.

With 6 broaches are designated for the mined material, with which degraded material can be passed to a running in the machine longitudinal direction Abförderein- direction. By means of the discharge device, the mined material is transported to the rear end 7 of the machine, where it is transferred, for example, to a stationary discharge device in the form of a belt or chain conveyor. The machine 1 further has a crawler undercarriage 8.

On the machine frame of the machine 1 guide rails 9 are arranged on both sides of the machine longitudinal center plane, in which a movable platform 10 is slidably guided in the direction of the double arrow 11. The traveling platform 10 carries a plurality of track removal means, namely a hoisting crane 12, a Ausbaumanipulator 13 and an anchor drilling and setting device 14. The movable platform 10 is in Fig. 1 in the retracted Position shown. In this parking position, the track removal facilities 12, 13 and 14 are in the folded state to minimize space consumption and to hinder the cutting process as little as possible. Thus, for example, the telescopic boom 15 of the lifting crane 12 is pivoted downwards, and in particular into a position parallel to the movable platform 10. Also, the telescopic arm 16 of the Ausbaumanipulators 13 is located in a downwardly pivoted position, whereby the gripper 17 of the Ausbaumanipulators comes to rest on the movable platform 10. The anchor drilling and setting device 14 comprises a pivoting device 18 with which the anchor drilling and setting device 14 can be pivoted back and forth between the parking position shown in FIG. 1 and the operating position illustrated in FIG. 3. In the parking position shown in FIG. 1, the anchor drilling and setting device 14 preferably extends transversely to the machine longitudinal direction, as can be seen particularly clearly in the front view according to FIG. 2.

Setting device 14 protrude only the support stamp 19 of the movable platform 10.

In the front view according to FIG. 2, it can be seen that the guide rails 9 each have a U-shaped cross-section which encompasses lateral guide elements 20 of the movable platform 10. Furthermore, it can be seen that the anchor drilling and setting device 14 is transversely positioned in the parking position, that extends transversely to the machine longitudinal direction. Furthermore, in Fig. 2 arranged between the two broaches 6, extending in the machine longitudinal direction discharge device 21 can be seen. In Fig. 3, the machine shown in Fig. 1 with the platform 10 moved forward and shown in the operating position carried out roadway equipment. The movable platform 10 has been pushed forward by means of the schematically illustrated displacement drive 22, wherein the displacement drive is formed, for example, by a chain drive. In the pushed forward position of the platform 10, this is supported on a support 23 of the cantilever arm 2 from. The telescopic arm 16 of the Ausbaumanipulators 13 has been extended and pivoted by means of the hydraulic cylinder piston unit 24 upwards. The pivot axis of the arm 16 is designated by 25. The gripping device 17 is also in the operating position and is pivotally attached to the arm 16 via a hinge 26. The pivot drive of the gripping device 17 is formed by the hydraulic cylinder piston unit 27. The gripping device 17 has two receiving pockets 28, in which, as shown in FIG. 5, in each case a removal sheet can be received or held.

The Ankerbohr- and -Setzeinrichtung 14 is pivoted by means of the pivoting device 18 from the parking position (Fig. 1) in the operating position (Fig. 3). For this purpose, the pivoting device 18 comprises a pivot arm 28 which can be pivoted about the pivot axis 30 by means of the hydraulic cylinder piston unit 29. The pivot arm 28 carries a rollover 31 to which the anchor drilling and setting device 14 is attached and which allows pivoting of the anchor drilling and setting device 14 about the pivot axis 32. 3, it can be seen that the anchor drilling and setting device 14 is set at right angles to the roof in the operating position. side positioning of Ankerbohr- and -Setzeinrichtung 14 and the Ausbaumanipulators 13 is made so that anchors can be set between the recorded in the receiving pockets 28 of the gripping device 17 Äusbaubögen NEN. Starting from the position shown in Fig. 3, the Ankerbohr- and -Setzeinrichtung 14 can be pivoted about the axis 32, which can be set in the lying between the two Ausaubögen vertical plane in the entire route profile anchor.

In Fig. 4, the anchor drilling and setting device 14 is shown in a downwardly pivoted position, can be placed in the anchor near the sole. It can also be seen in both FIG. 3 and FIG. 4 that the anchor drilling and setting device 1 can be supported and stabilized with the aid of support dies 19 that can be extended against the sole. Furthermore, a lowered work platform 33 can be seen on each side of the machine longitudinal center plane, which allows the operating personnel to get closer to the expansion bows or to the anchor drilling and setting device 14.

In Fig. 4, the route profile is designated 34. In the gripping device 17 of the expansion arch 35 is added, which supports the route profile with the interposition of stiffening elements 36. Furthermore, a delay mat 37 can be seen, which is pressed by means of a arranged on the gripping device 17 bow-like support means 38 against the ridge.

In the oblique view according to FIG. 5, an entire route section can now be seen, into which a plurality of expansion arches 35 for stabilizing the route profile 34 be introduced. It can be seen that in each case two path arcs 35 are received in the gripping device 17 or their receiving pockets 28. Incidentally, the illustration according to FIG. 5 corresponds to FIGS. 3 and 4, and the same reference numerals have been retained accordingly.
