Description

Ssterreiebischis fst «camouflages AT513 136B1 2014-02-15

The invention relates to a safety system for poles or the like. Structures, wherein a safety rope with the aid of a Vorseils on a building upwards and pulled over a cable deflection on the building at an upper deflection and secured in Ösenelementen on the building, wherein the fore rope extends upwardly in the erected state and downwardly from the upper turnaround in a down-run, and wherein a connector at the lower end of the up-run of the foresail is provided for connection to one end of the safety rope.

Such a security system is known from US 5,417,303 A. Specifically, here a Vorseil is shot with the help of, for example, an air rifle over an upper cross member on the pole line, and with the help of this Vorseils then the heavier safety rope is pulled up by hand. Both ends of the safety rope are then fixed in the foot area of the mast, and the one Seiltrum, the upward strand, is fixed to the mast handle in karabinerartigen Ösenelementen, with elastically deflectable arms. This fixation of the safety rope in the eyelet elements on the mast handle must be done separately by a person when climbing the mast. Another disadvantage is that in the event of a fall in the rope, the eye elements with the resiliently deformable arms give under the forces occurring during the fall and can open, so that the safety rope escape from the eye element and so can not properly exercise its security function. Furthermore, it is problematic that when the ropes or safety rope is left hanging on the pole after use, these ropes can be easily removed and taken away by unauthorized persons. However, if the safety rope is removed again each time, then with each new climbing the line masts not only a safety rope to raise, but also fix again and again in the eye elements.

From DE 299 03 258 U1 a device for securing persons who work on wooden poles is known. The safety rope is fixed by means of a ring on the wooden mast, which is tilted by means of a tension belt in an inclined position, so as to be fixed in position on the mast. The ring is mounted with the help of a telescopic pole on the wooden pole. This safety device is thus usable only on comparatively simple, low wooden poles, and there are no security elements, such as suspension eyes or the like. Ösenelemente, for fixing the rope on the mast.

In DE 199 61 352 A1 a fall protection for lattice towers and similar structures is disclosed, wherein a safety rope with a high local extensibility obliquely attached to the mast and tensioned by means of a cable tensioner. The unused rope length is stored in a basket on the ground. An attachment of the rope in Ösenelementen, for fixing to the mast, or a mounting of the safety rope with the aid of a Vorseils is not described.

In DE 20 2004 004 117 U1 a climbing aid for ladders is further known, in which a guided in an endless loop rope (traction means) is provided, what a person can attach to the fuse. The person should be supported when climbing by pulling up the Seiltrums. For this purpose, the movement of the traction means is detected, and the traction means is driven depending on the detection result, wherein the drive means provided for the drive of the traction means also includes a slip clutch with torque limiter.

From EP 577 587 B1, on the other hand, it is known to attach to pylons special risers in which connects to a rod-shaped tread part at the free outer end as Ösenelement a hanger, which forms a tread limit and Abrutschsicherung, and especially for hanging a safety rope for a mast climbing person serves. The hanger is formed by a helically bent rod portion of the riser, the helix preferably about 1¼ turns 1 / 15th

AT513 136B1 2014-02-15 so that the safety rope can be hooked into the helix hanger from above when the person is climbing onto the mast.

These safety climbing bars have proven themselves in practice, but in this system as well as similar systems, such as carabiners on the risers for attaching the safety rope, disadvantage that the mast climbing person the safety rope when climbing carry with you and successively in the respective hooks or the like must hang. It should be noted that the mast height may be, for example, 50 m and more, so that the weight of such a long safety rope is extremely high. In addition, in the event of slipping and falling of the ascending person also a certain drop height - according to the distance to the next lower hanger - given, which can certainly mean a significant burden on the falling person despite backup. This risk is in particular also given the respective Einhängvorgang when ascending, an additional incidental activity.

It is now an object of the present invention to remedy this situation and to provide a security system in which not only the weight load can be omitted by a mitzunehmendes safety rope for an ascending person, but overall the activities are facilitated. The invention also seeks an expedient solution in which a permanent attachment of a safety rope on the respective pole or the like. Construction is avoided, so as to steal such but relatively expensive and costly safety ropes as well as the attachment of complex safety ropes in large numbers, at all Pylons or the like. Structures to avoid in a permanent form. On the other hand, a - relatively easy and inexpensive - Vorseil can remain on the building, with an unauthorized removal of this Vorseils should be prevented if possible.

The security system according to the invention has to solve this problem, the features specified in claim 1.

Advantageous embodiments and further developments are specified in the dependent claims.

In the present security system, a comparatively thin, simple, low-cost overhead rope, e.g. a plastic rope, permanently attached to the structure, in particular pylon or the like., Attached, wherein it is passed through loop elements or Einhängösen. This pre-rope has such a length that it extends in the attached state on the structure, in particular pylon or the like. In an upward Trum up to an upper diverter and from there in a downward Trum back down. At the deflection of a deflection for the cable or safety rope is attached. The foresail has a free lower end in the upward strand, which is connected in case of need with a transported safety rope, for which purpose connection elements, such as in particular hooks and loops, can be provided. The other (front) end of the pre-line, which is the lower end of the down-run, is fixed in the lower part of the structure or line mast or the like.

Accordingly, the respective safety rope can be transported in case of need and raised with the help of the Vorseils on the building or the mast, mobile mast or the like. As desired. For this purpose, a drive means is provided with a role for the Vorseil, which rolls up the Vorseil starting with the lower end of the downstream Trum in operation, so as to pull up on the other side by means of the upward run of the Vorseils the safety rope and over to pull the diverter. An essential advantage of this system is that the securing part is automatically pulled by means of the pre-cable through the eyelet elements (suspension eyes), so that a subsequent separate fixing of the rope in the eyelet elements is unnecessary.

The two lower ends of the roughing rope, if this was attached to the building or pylon or the like., By a particular closable cover 2/15

SsüeiRidösdses pitwiarot AT513 136B1 2014-02-15 be secured against unauthorized access.

As deflection, for example, arcuate sliding elements or-preferably - a deflection roller, or a plurality of pulleys are provided one behind the other.

As a drive device, for example, in the simple case serve a hand crank, which is coupled to the role for the Vorseil, preferably, however, a motor, in particular an electric motor is provided.

Thus, after the dismount of the person from the building or pylon or the like. The safety rope can be obtained again, it is expedient to drive the Vorseil or the safety rope in the reverse direction, and accordingly, the drive means may optionally be followed by the engine Have reversing gear.

In the case of an electric motor for the drive device, as this is particularly preferred, a battery may be provided for supplying power to this electric motor. It is also conceivable to provide a rechargeable battery, an accumulator, wherein a photovoltaic system for feeding this rechargeable battery in the area of the structure or line masts or the like. Can be provided.

In order to forcibly drive when securing the safety rope in the downward direction, also a roller device may be provided, which is preferably coupled to the same drive means with which the drive and take-up roller is connected for the Vorseil.

For storing the safety rope, a cable bag can be provided which allows the transport of the safety rope to and from the building in a compact unit, and which may also be stored in a lockable housing on the building - at least temporarily.

To secure the Vorseil-ends and optionally the drive device, if this is to remain in place, for example, an openable housing, in particular with down folding housing parts, are attached to the building or mast, so in the closed, locked state the Vorseil role and possibly the drive device, possibly together with the safety rope roller device to secure against unauthorized access.

The invention also relates to a (power) pole with a safety system as indicated above. In this case, this line mast climbing rungs on a mast corner handle, which have hooks on the freely projecting ends. Furthermore, a pre-rope as indicated above, with an up-run and a down-run, is attached to this mast permanently, wherein the pre-rope extends over an upper deflector, which is mounted on the top of the pole. In the lower portion of the pipe mast, a drive means is provided with a drive and take-up roll for the leader, the lower end of the down run of the leader being connected to this roll so that when this roll is turned, the leader is wound on that roll and can be pulled up with the up-run. The pre-cable has at its free end on the upward strand preferably on a connecting element in the form of a hook, which cooperates with a loop at the end of the safety rope, so as to raise the safety rope on demand on the pole.

With the present security system, a person who wants to ascend the structure, such as a pylon, freed from the weight load by the safety rope. The person can thereby easily using a conventional fall arrester or fall arrester, also short (running) "fall arrester " called, are secured to the safety rope after its mounting, wherein the ascending at each hanger, through which the safety rope extends, the safety rope is posted briefly from this hanger so as to allow passage of the fall arrester. Immediately thereafter, the safety rope is immediately coupled back into the hanger, so the 3/15

iHierrecrase-ts ptiszimX AT513 136B1 2014-02-15 desired safety. In the event of a fall, such a fall arrest device immediately, without drop height, stops this fall and thus the person, who is therefore hardly exposed to physical strain in such a fall and learns in comparison to the previous systems, a gentle catch.

The invention will be further explained with reference to the drawing, particularly preferred embodiments shown in the drawing, to which, however, it should not be limited. In detail, in the drawing: Fig. 2 Fig. 3 Fig. 4 Fig. 4 Fig. 4B Fig. 5 [Fig. 4] Fig. 5 [Fig. Figure 9 shows schematically, as an example of a building with a safety system, an exemplary pole in view, with a safety rope attached; a corresponding view of a comparable line mast, wherein parts of the height of the line mast are broken away, for illustrating the course of a roughing line, with a comparison with respect to 1 modified deflection; 2 in a comparable schematic view, with part broken away, but now a part of the safety rope is already shown with the help of the pre-cable wound up; a view of a detail IV of Figure 3, illustrating a drive and take-up role for the Vorseil; a schematic end view of a fixing roller for the Vorseil, with partially wound Vorseil; a schematic detail view of a fixing element for the Vorseil on the pole line, as well as shown in Figure 2; a schematic view of a safety rope roller device with three rollers and a rope bag for the safety rope, according to the view V in Fig. 3; a connection arrangement foreline safety rope according to the detail V in Fig. 3; a detailed view of a drive device for the Vorseil and for the safety rope, more precisely for the drive roller for the Vorseil and for the roller device for the safety rope, wherein schematically a motor with clutch and reverse gear and waves and a battery are indicated; a schematic view of the use of a fall arrester; and in a view corresponding to FIG. 2, a pylon with a modified pre-rope fixation and a deflection device according to FIG. 1.

In Fig. 1, a pylon 1 is schematically illustrated in view. This pillar 1 is in a conventional manner from a truss structure and includes, for example, boom 2. At a corner post 3 of the line mast 1 risers 4 are provided laterally on both sides to allow a person to climb the corner post 3 and thus the pole 1 , The risers 4 have on their cantilevered ends of Fig. 1, not more apparent hanger elements, a training of the risers 4 is provided as safety risers as disclosed in EP 577 587 B1. Such a design of the risers as safety risers with helical hook-in eyes can be seen in FIGS. 2 and 3, wherein the risers for simplicity generally with 4 and the hanger eyes are designated 5. It can be seen from FIGS. 2 and 3 that not all risers 4 must be provided with outside hook-in eyes 5, i. it can meantime between simple climbing bars 4 with simple outside attacks 5 'as slip-off and the footing provided 4/15

S & midtts AT513 136B1 2014-02-15. This is in the present case, unlike in the case of the aforementioned EP 577 587 B1, therefore readily possible because, as will be mentioned in more detail below, a safety rope 6 (see Fig. 3) in advance, before the rising, is raised, so the safety rope 6 is already fixed to the mast 1 during the ascent of a person and does not engage the same "from level to level". necessary is.

In Fig. 1, the safety rope 6 is also shown in already aufgezogenem state, where it is seen that the safety rope 6 from the ground, from a rope bag 7 attached there, up to a deflection 8 at the upper end of the line mast 1 and from there back down to the ground, where it is fixed, extends.

1 to 3 is also schematically a base 9 of the line mast 1 recognizable, which is used to support the actual line mast 1, i. E. of its truss structure, serving on the ground.

2, a comparatively thin, light trailing rope 10 runs at the corner post 3 of the line mast 1 from a fixing point 11 near the bottom upwards, by hooking 5 of risers 4, to the upper deflection 8 and 8 'and of there again down to a roll-up and fixing device 12 shown only schematically. The deflection device 8 is formed in this example, as shown in FIG. 2 by a single rubberized, a relatively large diameter deflection roller 13. This deflecting roller 13 or generally the deflecting device 8 is assigned a weather protection 33 on the upper side so as to protect the deflecting roller 13 against rain or snow.

The fixing of the pre-cable 10 at 11 and 12 is carried out e.g. by means of hooks, cf. about the hook 25 in Fig. 6.

The Vorseil 10 is arranged in the arrangement shown in FIG. 2 permanently on the mast 1. To secure the lower ends of the leader 10, namely the free end of the upward run 10A as well as the free end of the down-run 10B, is a closable cover or a closable housing 14, for example, consisting of two pivotable 90 ° apart cup-shaped housing parts 14A, 14B, provided. In Fig. 3, these two Abdeckungs- or housing parts 14A, 14B in the unfolded, downwardly pivoted position (lying on the base 9) illustrated.

Furthermore, in Fig. 3 in the lower part of the corner handle 3 a -in Fig. 2 not shown - Vorseil roller 15 for fixing and winding of the pre-cable 10 is shown. For this winding of the leader 10 on the roller 15, a drive means 16 is provided, to which the roller 15 belongs, and which has a motor 17, see. Also Fig. 7. This engine 17 is preferably an electric motor which is powered by a battery 18 with energy. The motor 17 drives via a reversing gear not illustrated in more detail and via a shaft 19 to the pre-rope pulley 15; In a corresponding manner, the motor 17 can drive a middle roller 20 of a roller device or a roller apparatus 21 for the safety cable 6 via a shaft 19 ', cf. 3 and FIG. 7 and FIG. 5. The safety rope 6 is thereby removed from the cable bag 7 engaged with the corner post 3 of the line mast 1, as is shown more clearly in FIG. The rolling device 21 has two further rollers 22 (upper roller) and 23 (lower roller) in order to ensure a total safe guidance of the safety cable 6 when mounting as well as when pulling. It should be noted that the safety rope 6 may have, for example, a diameter of 10 mm to 15 mm and more, whereas the trailing rope 10 may be, for example, a plastic rope with a diameter of 3 mm. The rollers 20, 22 and 23 are as well as the roller 15 for the Vorseil in a conventional manner, not shown in detail, rotatably mounted on the corner post 3 of the line mast 1. It is also conceivable to arrange the bearing for the middle roller 20 of the rolling device 21 sprung, as indicated in Fig. 5 schematically at 24. In this way, a secure cable retrieval is ensured with the safety cable roller device or the roller apparatus 21, wherein the safety cable 6 is then stored in this collection or retraction of the safety rope 6 continuously in turns in the cable bag 7. 5.15

In an advantageous embodiment, the drive device 16 with the Vorseil roller 15 and with the rolling device 21, further with the motor 17 and the battery 18 and of course with the Shafts 19, 19 ', as illustrated in Fig. 7 (and also in Fig. 3), a separate unit, as such, if necessary, transported to the mast 1 and there in any conventional manner, such as by means of bolts or bolts, fixed or fixed at the corner handle 2, etc. After the attachment of this drive device 16, the two ends of the leader rope 10, namely the lower end of the upward run 10A and the lower end of the downward run 10B of the respective device 11 and 12 (see also Fig. 4A and 4B) solved and as shown in Fig. 2 seen moored.

With the lower end of the upward run 10A is via a compound VI, see. Fig. 6, namely with a hook 25 and a loop 2 6, the safety cable 6 is connected or coupled, and about this in Fig. 3 at VI schematically illustrated connection with a circle then the safety rope 6 is mounted by means of the pre-cable 10, wherein previously the foresail 10 with the lower end of the down-run 10B, which was previously solved by the fixing roller 12, was attached to the roller 15 in a conventional manner, so that the Vorseil 10 on this roller 15 then, when driven by the motor 17, can be wound up. The leader 10 is wound up in its entirety, i. the safety rope 6 is pulled up to the deflection 8 and pulled from there back down to the roller 15 and fixed there in a manner not shown in detail. Then a safe climb on the pole 1 is possible.

To secure the respective ascending person, a fall arrester 27 which is conventional per se can be used, as shown schematically in FIG. 8; this fall arrester 27 is connected via a short connection 28 with a seat belt 29 of the respective person, as also shown in FIG. 8 can be seen. Since the safety rope 6 is firmly anchored in the mounted state on the pole 1, the fall height is practically zero in the event of a fall of a person, so that even a small amount of energy or low forces act on the person.

When ascending a person with such a backup, with a safety rope 6 embracing fall arrester 27 is at each safety riser 4, where a hanger loop 5 is present, the safety rope 6 temporarily briefly suspended from the hanger 5, so the fall arrester 27 this hanger 5 can easily pass.

The helical Einhängösen 5 allow an extremely simple unhooking and unhooking of the safety rope 6 (or before hanging the foreline 10) on the open coil and form as mentioned also a slip-off.

From Fig. 4A, the roller-shaped locking device 12 is schematically illustrated for the trailing rope 10; 4B shows, in a detailed view, the fixing device 11 for the foreline 10 on the side on which the securing cable 6 is to be drawn. In this embodiment according to FIG. 4B, the leading rope - e.g. with the hook 25 - is hooked into a slot 30 of a holder 31, after which it is secured in this slot 30 by means of a pivoting pocket 32. A similar fixation is possible on the other Vorseil-end of the locking device 12.

9, an embodiment is shown in a view similar to Fig. 2 or 3, in which the deflection device 8 at the upper deflection point 8 'on the mast 1 instead of a large guide roller 13, as shown in FIGS. 2 and 3 , is realized with three relatively small pulleys 13A, 13B and 13C, which are freely rotatably mounted on an angle-shaped bracket 13D.

Further, in Fig. 9, the lower ends of the upward run 10A and the downward run 10B of the leader 10 are shown in broken lines at a greater height (about 2.5 to 3 m above the ground), and there in the case in that only the front rope 10 is present and the safety rope 6 is not raised contrary to the illustration in FIG. 9, are secured against unauthorized access in a closable, comparatively small receiving station 14 '. Also 6/15

Here, by the way, the drive device 16 is preferably attached to the pole 1 in the lower area only when needed, to the safety rope 6 from the cable bag 7, which is then also placed only in this case , with the help of the Vorseils 10, which is rolled up on the roll 15 to raise, finally to achieve an arrangement with the safety rope 6 as shown in Fig. 1 and 9.

In the embodiment according to FIGS. 2 and 3, with the two pivotable cover or housing halves 14A, 14B, the two free ends of the foresail 10 are located in a deeper area, approximately at a height of between 1 m and 1.5 m, so that access to these Vorseil-ends after opening the cover 14 without any lifts is possible. In contrast, in the embodiment of FIG. 9 access to the two ends of the leader 10 is only possible with the aid of a ladder or the like, thereby providing increased security against unauthorized access.

If the invention has been illustrated above in a preferred embodiment using the example of a (power) line mast 1, so is of course an application of the present security system in other comparable structures, such as mobile phones, but also in (steep) pitched roofs , even on facades, conceivable.

Furthermore, it is possible to secure the mounted safety cable 6, for example in the region of the upper deflection device 8, for example with the aid of electrically operated brake shoes (not shown) below the weather protection 33; In this case, a further downward pulling the safety rope 6 on the left side of the mast 1 in the drawing unnecessary, and it can be used about half as long safety rope 6. For actuating the brake shoes, e.g. the battery 18 (Figure 7) the required electrical energy are removed. 7/15
