Definitions
- the invention relates to a fastening system on the ridge of a route under lying or tunneling, wherein the fastening system comprises a rock anchor to which a stop device is attached.
- Rock anchors usually consist of an anchor rod, which projects into the ridge, with an anchor plate attached to the end of the anchor rod with an anchor nut. With the help of these rock anchors, the track is secured in the bump and ridge area. By such rock anchors in particular the falling of plate-shaped rock layers or salt layers should be prevented. That is, such
- rock bolts as load anchors and to such rock anchors
- Attach lifting devices eg lifting hooks
- load handling attachments serve to secure loads such as e.g. of supply lines (pipes), power cables or lighting devices. From this it is clear that the purpose of such rock anchors is diverse.
- the subject of the present invention is a fastening system for mounting on the ridges underground.
- a fastening system as a fall protection, which meets the requirements of occupational safety, is characterized
- the object of the invention is therefore that the stop device is connected to the rock anchor freely rotatable with the rock anchor. This against the following background: The people who perform the assembly work, move and they turn u. U. also to your own Axis. In particular, in the event of a crash by the
- Swing anchor device secured person on the safety line. Due to the fact that the stop device is freely rotatable on the rock bolt (swivel function), there is no danger of it moving away from the rock anchor
- Rock anchor turns off when the secured person is connected via a harness with the corresponding components by a snap hook with the anchor device.
- Receiving loads are attached to the rock anchor or be.
- the eyelet described in previously discussed WO 2012/053965 A1 is directly and not freely rotatable by a thread with the actual
- the fastening system according to the invention can thus be used wherever a personal protection against falling is required. This is the case at a working height of over one meter, if other safety devices are not available or are difficult to use depending on the situation.
- the stop device has a screw-in sleeve for connection to the rock bolt.
- a threaded connection is provided between the rock bolt and the anchor member, wherein in particular a thread called a self-locking thread, for example in the form of a trapezoidal thread is used.
- a self-locking thread for example in the form of a trapezoidal thread.
- Anchoring device by a screw-in sleeve with internal thread, wherein the screw-in sleeve is screwed onto the anchor rod of the rock anchor. Furthermore, it has advantageous a covenant to
- a bearing is arranged between the collar and the o vertebral body, in particular an axial ball bearing which minimizes the friction between the sleeve-shaped vertebral body on the one hand and the collar on the screw-in sleeve on the other hand. It is conceivable, however, not only the use of a thrust bearing in the form of a
- Ball bearings but also the use of a corresponding plain bearing.
- Friction forces can rotate freely, without the anchor sleeve from the anchor rod of the rock anchor dissolves.
- the screw head can in this case be designed in the manner of the tip of a screwdriver, whereby the possibility is opened, from the bottom by means of a rod and the corresponding Aufschraubvorraum, the end a cross-sectionally U-shaped
- Screw-in sleeve and anchor rod are at least four threads engaged with each other.
- the number of threads can also vary depending on the anchor properties.
- the display member is in this case designed in particular as a pin, wherein the pin in a bore in the screw head and / or in the covenant of
- Cartridge is seated and with one end in the cavity of the
- Anchoring device is in this case non-positively, for example via friction. It is clear from this that the extent to which the pin protrudes into the screw-in sleeve determines the minimum screw-on depth of the anchor sleeve on the bolt of the rock bolt. Because when it reaches
- the stop device can be used several times.
- FIG. 1 shows a side view in section of the
- Fig. 2 shows a view according to the line II-II of Fig. 1.
- the rock anchor generally designated 1
- the rock anchor comprises the anchor rod 8 from which a part 3 projects freely downwards out of the ridge.
- an anchor plate 5 is fastened by means of an anchor nut 4 on the protruding part of the anchor rod 3
- Anchoring device 20 which are also referred to as a stop lug
- Screw head 30 (eg formed in the manner of the tip of a screwdriver), wherein the screw head 30 of the connection with a
- the designated anchor member 40 includes the screw 22 with the collar 28, the screw head 30, the ball bearing 44 and the
- the vertebral body 24 has as a suspension link on a movable bracket 42, the hanging example of a snap hook of the
- Fuse harnesses of e.g. Serving with the assembly of loads For example, there is an axial ball bearing 44 between the end face of the sleeve-shaped vertebral body 24 and the collar 28 on the screw-in sleeve so that the friction between the vertebral body 24 and the collar 28 is reduced when the vertebral body 24 surrounds the screw-in sleeve fixedly connected to the collar 28 22 turns. In this respect, there is a slight radial distance between the sleeve-shaped
- Vertebral body and the screw-in sleeve Secured is the screw 22 with the vertebral body 24 by a locking ring 27 z. B. in the form of a snap ring.
- the collar 28 and the screw head 30 to the screw 22 have a bore 34.
- the bore 34 serves to receive a pin 36 as a display member for determining the depth of screwing the screw 22 on the protruding part 3 of the anchor rod 8 of the rock anchor 1. That is when the pin 36 abuts with its end face against the end face of the anchor rod 8 of the rock anchor 1, this is then ejected from the bore 34. The result is that it falls down and hanging on the safety cable 37, which is attached via a mounting ring 38 on the bracket 42 down. This will cause the person to unscrew the Anchoring device 20 performs, to recognize that the
