Definitions
- the invention relates to an anchor drilling and setting device for drilling and setting anchors in the longitudinal center plane of a tunneling or mining machine in the roof, the tunneling or mining machine having at least one support near the face, which between The ridge and sole can be clamped and is articulated to the front end of the machine and to the rear area of the machine by means of links running in the longitudinal direction of the machine.
- anchor drilling and setting devices When driving on routes, a certain anchor pattern must be observed to protect the rock protection.
- anchor drilling and setting devices outside the outline of the plan view of a tunnel boring machine or cutting machine, and in particular when brittle slopes are to be feared, these anchorings should be made as close as possible to the working face in order to keep the undeveloped or unsecured area as short as possible.
- Such anchor drilling and setting devices can be connected to the cutting machine or the tunnel boring machine in order to ensure the desired position near the face at predetermined distances from the face.
- Such devices are described, for example, in AT-PS 392 119, in which the anchor drilling and setting devices are connected in an articulated manner to the cutting machine and can be hydraulically clamped between the roof and the bottom of the route.
- a tunneling or extraction machine of the type mentioned at the outset, with which, however, only anchors can also be placed outside the longitudinal center plane, is described in GB-A 2 232 429.
- the movable track boring or extraction machine has a front support which is articulated to the front end of the frame of the machine.
- the support which extends between the sole and the roof, is moreover connected to the rear end of the machine via a link, the anchor drilling and setting devices being arranged on the support laterally outside the pivoting path of the cantilever arm.
- the cantilever arm which usually also carries the drive motor for the cutting rollers, is relatively wide, so that anchor holes are only relatively far out of the way. can be made in the middle and anchors can only be set outside this route center.
- the invention now aims to improve such a machine, as can be seen, for example, from GB-A 2 232 429, in such a way that central central anchor bores can also be drilled as close as possible to the working face and central anchors can be placed near the working face .
- the design according to the invention essentially consists in the fact that the anchor drilling and setting device can be pivoted about an axis running transversely to the machine longitudinal direction and can be fixed in the swivel position with at least one handlebar running in the longitudinal direction of the machine.
- anchor drilling and setting device is attached to at least one of the links running in the longitudinal direction of the machine pivotable about an axis extending transversely to the longitudinal direction of the machine, makes it possible to carry out anchor holes closer to the face, furthermore also when using long anchor boring bars and long ones
- Anchors are offered the option of adopting a correspondingly low transport position, for which the anchor drilling and setting device can be pivoted, for example, essentially parallel to the handlebars.
- the anchor drilling and setting device can also be pivoted into such a position so that a low-construction machine is achieved. which is easier to maneuver.
- the design is such that the link running in the longitudinal direction of the machine has two arms which are essentially parallel to one another and that the anchor drilling and setting device is pivotably mounted on a support connecting the arms. Especially when using parallel arms to guide the front For reasons of vibration decoupling, it makes sense to articulate the two arms separately on the ridge cap, a space being created between such arms, in which the anchor drilling and setting device can be pivoted in a non-operating position.
- the design is advantageously made such that the carrier has joints with the arms connected is.
- the articulation of the carrier for the anchor drilling and setting device can be made in a structurally particularly simple manner so that the arms on their mutually facing inner sides parallel to the arms carry bolts or bearing eyes and that the carrier engages around the bolts bearing eyes or into the bearing eyes Has bolts, which at the same time also creates the possibility of moving the anchor drilling and setting device with the carrier in the manner of a slide in the longitudinal direction of the handlebars or the arms of the handlebars and positioning them accordingly.
- the anchor drilling and setting device can thus also be brought closer to the working face.
- the anchor drilling and setting device can be used in a substantially bank-right direction, ie with the formation of bores orthogonal to the longitudinal axis of the line, it being possible, of course, to use any pivot positions of the anchor drilling and setting device to achieve anchoring closer to the face.
- a further decoupling and securing of the carrier against overloading with high vibrations can be achieved in that at least one bearing eye is designed as an elongated hole, the longer axis of which runs in the direction or parallel to the plane spanned by the arms. In this way, a compensation is created when the arms of the handlebar parallel to each other are elastically expanded, for example by high loads.
- the design is such that the anchor drilling and setting devices are arranged on telescopically displaceable slides, one of which can be pivoted about the axis running transversely to the supports and can be fixed in its pivoting position is connected to a rotary actuator.
- the design is advantageously made such that the swivel axis of the anchor drilling and setting device running transversely to the longitudinal axis of the machine is located at a location facing away from the working face the horizontal pivot axis of a cantilever arm for the cutting tools, in particular cutting rollers, is arranged.
- the central discharge conveyor which in other known constructions in which center anchors are placed behind the machine, has to be pivoted out of the longitudinal axis of the machine, is arranged relatively deeply, so that there is a corresponding free space for inserting anchor rods and arranging them is guaranteed by boring bars.
- FIG. 1 shows a schematic side view of a machine according to the invention
- FIG. 2 shows a detail of the support and the articulation of the anchor drilling and setting device on the handlebars of the support
- FIG. 3 shows a section along the line III-III of FIG. 2nd 1 shows a tunnel boring machine 1, the extension arm 2 of which can be pivoted about a substantially horizontal axis 3 in the direction of the double arrow 4.
- the cutting tools are formed by cutting rollers 5, whereby the cutting rollers 5 can be pivoted between the base 6 and the ridge 7.
- a foot part 9 of a support 10 is articulated on the machine frame at the front end near the working face via a link 8, the support 10 being articulated about a pivot axis 13 on the rear part of the machine frame 12 via a link 11 running in the machine longitudinal direction.
- the link 11 carries a bearing eye, indicated schematically by 14, for an anchor drilling and setting device (not shown in more detail in FIG. 1).
- the cutting machine also has a crawler track 15, the rear end of the conveying device being designated 16.
- the swivel drive for pivoting the cantilever arm 2 in the direction of the double arrow 4 is denoted by 17.
- the link 11 is formed by two arms 18 which are essentially parallel to one another and which are connected to a ridge cap 20 via joints 19.
- the rear articulation axis is again identified by 13, the rear end of the machine part again being identified by 12.
- a carrier 21 is arranged, on which the anchor drilling and setting device is pivoted about a pivot axis 23.
- the swivel drive is designated 24 here, the anchor drilling and setting device 22 itself being designed as a telescopic device, the slides of which are telescopically displaceable relative to one another in the longitudinal direction are designated 25 and 26.
- the pivot axis 23 lies behind the horizontal pivot axis 3 of the cantilever arm 2, so that the lower end of the anchor drilling and setting device 22 in the fully extended or completely lowered position is relatively far into the machine interior can be lowered, which means that long anchor rods and long boring rods can also be inserted safely.
- the parking position, in which the carriage 25 can be pivoted essentially parallel to the plane spanned by the arms 18, is indicated schematically by broken lines.
- the carrier 21 is connected to the arms 18 via bolts, the bolt axis of which is designated 27 in FIG. 2. A detail of this articulation of the carrier on the arms 18 can be seen in FIG. 3.
- the indicated anchor drilling and setting device 22 is in turn mounted pivotally about the axis 23 in the bearing eye 14.
- the carrier 21 has bearing eyes 29 which engage around bolts 30, the axes of which are in turn designated 27.
- the bolts 30 are connected to the arms 18 via corresponding tabs 31.
- one of the bearing eyes 29 has an elongated hole 32, so that the bolt 30 is movably held in this elongated hole in order in this way to be able to accommodate elastic widening of the arms 18 without the support 21 being supported to destroy.
- a corresponding anchoring of a center bolt or center anchor can also be achieved with the cutting operation while extraction or during cutting operation, additional side anchors in a conventional manner, for example via anchor drilling and setting devices arranged in the front support , can be introduced.
- the articulated arrangement of the anchor drilling and setting device on the longitudinal struts or links of the machine support allows the correct height adjustment on the one hand and the pivoting into a parking position to achieve a particularly low height for moving the machine.
- the two arms of the handlebar can move in the vertical direction during the cutting operation, a corresponding compensation being ensured by the special design of the mounting of the carrier on the arms of the handlebar.
- a central anchor can already be placed at a short distance from the face, no modifications to the removal device being necessary, as was necessary, for example, in the design according to WO 96/17155.
