Definitions
- the invention relates to a fall protection device for a gangway or working platform, comprising at least two support posts, which are articulated at their base points by means of a first swivel joint on the walking or working platform.
- the railing After completion of the activities of the operating personnel, however, the railing is brought into a folded or low-lying "rest position" and secured against unintentional automatic (re) erecting; the carrier vehicle then fulfills the permissible clearance dimensions and can be moved in traffic.
- the railing supports are pivotably connected both to the gangway or working platform and to the railing longitudinal bars.
- the erection or folding down of the railing can according to the teaching of DE 33 20 969 A1 via a movable lower Part of an essentially vertical climbing aid provided for climbing the gangway, for example in the form of a foldable or vertically displaceable lower part of the climbing aid.
- a teaching similar to this is conveyed by the AU 725447 B .
- a walking and working platform with a foldable handrail which can be actuated (ie can be raised or folded down) by means of an arrangement of two sub-elements that are pivotably coupled to one another, which are hinged on the one hand to the handrail of the handrail and on the other hand to the handrail of a climbing aid.
- a railing provided with a handrail has often proven to be disadvantageous for the operating personnel, for example in operational practice when loading car transport vehicles, since the free space remaining between the load and railing is very narrow and an operator cannot pass such a narrow point.
- the invention is therefore based on the object of providing a fall protection device for a gangway or working platform, comprising at least two support posts which are attached to their base points are articulated to the walking or working platform by means of a first swivel joint, which represents an alternative to the known prior art and in particular enables more ergonomic working conditions for the operating personnel.
- each support post has an angle lever in the area of the base, the distal end of which is coupled to a rigid rod connecting the angle levers of all support posts by means of a second swivel joint.
- a forced guidance of the support posts is achieved, which enables a transmission of, in particular, thrust forces between the support posts.
- the particular advantage of the invention is that this takes place by means of a force transmission component arranged outside the work area of the operating personnel.
- a rotational movement applied to a first support post about its first pivot joint is transmitted via the inventive arrangement of angle levers and the rigid rod connecting these angle levers to the other support posts of the same fall protection device, so that these other support posts perform a synchronous rotational movement.
- fall protection with flexible barrier elements such as ropes, chains or rope-tensioned tarpaulins etc. can be used.
- These flexible shut-off elements can be pushed out of their basic position to a certain extent by the operating personnel, provided that this is necessary due to restricted space in the area of the gangway or working platform. In this way, the operating personnel can increase the clearance between the load and the fall protection device, which is necessary for more ergonomic work, without the protective function of the fall protection device being canceled as a result.
- the fall arrest device has at least one rope stretched in the free space between at least two support posts, the rope being pivotably connected to the support posts by means of a cable eye each.
- a cable eye each.
- the cable eye can be formed by turning over a cable end and fixing it against the cable body by means of cable clamps.
- the rope eye is preferably reinforced by an inserted thimble. This reduces the friction between the rope and the receiving pin and thus also its wear.
- At least one support post can be fixed in the area of the base point by means of a releasable lock against rotation about the first pivot joint.
- This locking device can be designed, for example, in the form of a footrest, which can be adjusted from a first rest position by linear displacement in the direction of the support post into a second engagement position that locks the support post against pivoting about its first pivot joint. In this way, the fall protection is secured either in an unfolded working position against unintentional folding down or in a folded down rest position against unintentional erecting.
- the invention also extends to a vehicle with at least one loading area designed for the transport of motor vehicles, the walking or working platform of which has a fall protection device with at least one of the aforementioned features.
- FIG 2 is a perspective view of the working platform (7) (or “loading platform") of a double-decker car transport vehicle with a fall protection device according to the invention arranged in the longitudinal direction of the vehicle, which has an arrangement of three support posts (ie two end supports (1, 2) and a central support arranged between them (17)).
- Ropes (13) are stretched between the support posts, each of which is pivotably mounted on the end supports (1, 2) by means of a rope eye and thimble, and is guided through eyelets on the central support (17) and is mounted on these in a linearly displaceable manner along its length.
- the fall protection devices are arranged on the working platform on both sides of the longitudinal direction of the vehicle and can have any lengthways or any number of support posts.
- it is a rail vehicle; however, the invention can also be applied in an identical manner to road vehicles.
- the vehicle has a lateral climbing aid (15) to the working platform (7), which is similar to a rung ladder and from the in Figure 2 only the top step and a handrail (16) are shown.
- the fall protection is in the upright working position. In the area of the exit from the climbing aid (15) to the work platform (7), the fall protection is interrupted so that the operating personnel can access the work platform.
- Figure 2 only one side wall, but not the floor of the working platform (7) is shown.
- an actuating device which is made up of two pivotably coupled (20) sub-elements (18, 19), which at a first end has a pivot coupling (21) to the end support (1) closest to the climbing aid and to one end at the second end a pivot coupling (22) to the handrail (16) of the climbing aid (15).
- the axes of rotation of the swivel joints (20, 21, 22) are aligned parallel to one another.
- the first sub-element (18) closest to the climbing aid is designed as a rigid, angled rod; the closest to the end support second sub-element (19) as a wire rope, which is mounted in the swivel joints (20, 21) in a manner analogous to the ropes (13) stretched between the support posts by means of a rope eye and thimble.
- the first rod-like sub-element (18) is rotated about the swivel joint (22).
- the sub-element (18) is moved counterclockwise around the swivel joint (22) in the area of the articulated connection (20), ie deflected upwards.
- the second sub-element (19) follows this movement until the upright working position of the fall protection device is reached.
- the actuation of the fall protection by the operating personnel can be additionally supported.
- the fall protection is folded down into the rest position in the opposite way.
- FIG 1 is a detailed view of a locking device designed as a footrest (14), by means of which the first end support (1) can be fixed against rotation about its first pivot joint (5).
- the footrest (14) can be adjusted from a first rest position by linear displacement in the direction of the end support (1) into a second engagement position that locks the end support against pivoting about its first swivel joint (5).
- the footrest can be locked against unintentional actuation both in the rest position and in the engaged position.
- the locking device shown is part of a second fall protection device, which is a mirror image of the one in Figure 2 shown first fall protection, ie to the left of the climbing aid (15) is arranged.

Description
Die Erfindung betrifft eine Absturzsicherung für eine Lauf- oder Arbeitsbühne, umfassend mindestens zwei Stützpfosten, welche an ihren Fußpunkten mittels jeweils eines ersten Drehgelenks an der Lauf- oder Arbeitsbühne angelenkt sind.The invention relates to a fall protection device for a gangway or working platform, comprising at least two support posts, which are articulated at their base points by means of a first swivel joint on the walking or working platform.
Verschiedene Arten von Nutzfahrzeugen weisen erhöht liegende Ladungsebenen auf und / oder müssen für Be- oder Entladungszwecke sowie bei Kontrollen im Dachbereich des Fahrzeuges durch Bedienpersonal begangen werden. Zu diesem Zweck weisen diese Fahrzeuge Laufbühnen oder -stege in oftmals großer Höhe über dem Boden auf. Zum Zwecke der Arbeitssicherheit müssen diese Laufbühnen mit Absturzsicherungen - üblicherweise in Form eines Geländers - ausgestattet sein. Als Beispiel können hierfür doppelstöckige Autotransport-Fahrzeuge oder auch Tank- und Silofahrzeuge mit im Dachbereich angeordneten Befüll- und / oder Kontrolleinrichtungen genannt werden. Dies ist unabhängig von der konkreten Ausprägung des Nutzfahrzeuges als Straßen- oder Schienenfahrzeug und umfasst ganz allgemein auch alle derartigen Wechselbehälter, wie z.B. Container, sowie sonstige Arbeitsbühnen, z.B. an Montage- oder Wartungsgeräten.Various types of commercial vehicles have elevated loading levels and / or must be used by operating personnel for loading or unloading purposes and during checks in the roof area of the vehicle. For this purpose, these vehicles have gangways or walkways, often at a great height above the ground. For the purpose of occupational safety, these gangways must be equipped with fall protection - usually in the form of a railing. Two-story car transport vehicles or tank and silo vehicles with filling and / or control devices arranged in the roof area can be cited as an example. This is independent of the specific form of the commercial vehicle as a road or rail vehicle and generally also includes all such swap bodies, such as containers, as well as other work platforms, e.g. on assembly or maintenance equipment.
Aus der
Bei allen bekannten Anwendungen derartiger Klappgeländer fehlt allerdings nach dem Aufklappen des Geländers in die Arbeitsstellung nicht nur eine für das Bedienpersonal zugängliche Halte- bzw. Griffmöglichkeit im Übergangsbereich zwischen der Aufstiegshilfe und der Lauf- bzw. Arbeitsbühne sondern auch eine Absturzsicherung im Bereich der durch die Aufstiegshilfe bedingten Lücke im Geländer. Diesbezüglich sind aus dem Stand der Technik allenfalls Behelfslösungen mittels vom Bedienpersonal einzuhängender Ketten o.ä. bekannt, auf deren Nutzung das Bedienpersonal in der Praxis aber aus Zeitgründen oder Bequemlichkeit oftmals verzichtet.In all known applications of such folding railings, however, after the railing is unfolded into the working position, not only is there a holding or grip option in the transition area between the climbing aid and the walking or working platform that is accessible to the operating personnel, but also a fall protection in the area of the climbing aid conditional gap in the railing. In this regard, makeshift solutions by means of chains or the like to be attached by the operating personnel are known from the prior art, but the use of which the operating personnel often foregoes in practice for reasons of time or convenience.
Aus der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Absturzsicherung für eine Lauf- oder Arbeitsbühne, umfassend mindestens zwei Stützpfosten, welche an ihren Fußpunkten mittels jeweils eines ersten Drehgelenks an der Lauf- oder Arbeitsbühne angelenkt sind, bereitzustellen, die eine Alternative zum vorbekannten Stand der Technik darstellt und insbesondere ergonomischere Arbeitsbedingungen für das Bedienpersonal ermöglicht.The invention is therefore based on the object of providing a fall protection device for a gangway or working platform, comprising at least two support posts which are attached to their base points are articulated to the walking or working platform by means of a first swivel joint, which represents an alternative to the known prior art and in particular enables more ergonomic working conditions for the operating personnel.
Erfindungsgemäß wird diese Aufgabe in Verbindung mit dem Oberbegriff des Schutzanspruches 1 dadurch gelöst, dass jeder Stützpfosten im Bereich des Fußpunktes einen Winkelhebel aufweist, dessen vom Stützpfosten entferntes distales Ende mittels eines zweiten Drehgelenkes mit einer die Winkelhebel aller Stützpfosten verbindenden starren Stange gekoppelt ist.
Auf diese Weise wird eine Zwangsführung der Stützpfosten erreicht, welche eine Übertragung von insbesondere Schubkräften zwischen den Stützpfosten ermöglicht. Der besondere Vorteil der Erfindung besteht darin, daß dieses mittels eines außerhalb des Arbeitsbereichs des Bedienpersonals angeordneten Kraftübertragungs-Bauelements erfolgt. Eine auf einen ersten Stützpfosten aufgebrachte Drehbewegung um dessen erstes Drehgelenk wird über die erfindungsgemäße Anordnung von Winkelhebeln und der diese Winkelhebel verbindenden starren Stange auf die übrigen Stützpfosten derselben Absturzsicherung übertragen, so daß diese übrigen Stützpfosten eine hierzu synchrone Drehbewegung ausführen. Auf diese Weise kann auf eine starren Handlauf im Arbeitsbereich des Bedienpersonals verzichtet werden und es können statt eines Geländers, welches einen festen Handlauf aufweist, auch Absturzsicherungen mit flexiblen Absperr-Elementen, wie z.B. Seilen, Ketten oder seilverspannten Planen etc. zum Einsatz kommen. Diese flexiblen Absperr-Elemente können durch das Bedienpersonal um ein gewisses Maß aus ihrer Grundstellung gedrückt werden, sofern beengte Platzverhältnisse im Bereich der Lauf- bzw. Arbeitsbühne dies erforderlich machen. Auf diese Weise kann das Bedienpersonal den für ein ergonomischeres Arbeiten nötigen Freiraum zwischen Ladegut und Absturzsicherung vergrößern, ohne daß hierdurch die schützende Funktion der Absturzsicherung aufgehoben würde.According to the invention, this object is achieved in connection with the preamble of
In this way, a forced guidance of the support posts is achieved, which enables a transmission of, in particular, thrust forces between the support posts. The particular advantage of the invention is that this takes place by means of a force transmission component arranged outside the work area of the operating personnel. A rotational movement applied to a first support post about its first pivot joint is transmitted via the inventive arrangement of angle levers and the rigid rod connecting these angle levers to the other support posts of the same fall protection device, so that these other support posts perform a synchronous rotational movement. In this way, there is no need for a rigid handrail in the work area of the operating personnel and, instead of a handrail with a fixed handrail, fall protection with flexible barrier elements such as ropes, chains or rope-tensioned tarpaulins etc. can be used. These flexible shut-off elements can be pushed out of their basic position to a certain extent by the operating personnel, provided that this is necessary due to restricted space in the area of the gangway or working platform. In this way, the operating personnel can increase the clearance between the load and the fall protection device, which is necessary for more ergonomic work, without the protective function of the fall protection device being canceled as a result.
Gemäß einer sinnvollen Ausgestaltung der Erfindung weist die Absturzsicherung mindestens ein im Freiraum zwischen mindestens zwei Stützpfosten aufgespanntes Seil auf, wobei das Seil mittels je eines Seilauges drehgelenkig mit den Stützpfosten verbunden ist. In besonders einfacher Weise ist dies durch einen vom Stützpfosten senkrecht abstehenden zylindrischen Aufnahmestift realisiert, der in das Seilauge eingreift und eine außenliegende Abschlußscheibe aufweist, deren Außendurchmesser den Innendurchmesser des Seilauges übersteigt und die ein Abfallen des Seilauges vom Aufnahmestift verhindert. Das Seilauge kann durch ein Umschlagen eines Seilendes und dessen Fixierung gegen den Seilkörper mittel Seilklemmen gebildet werden. In bevorzugter Weise ist das Seilauge durch eine eingelegte Kausche verstärkt. Dies reduziert die Reibung zwischen Seil und Aufnahmestift und somit auch dessen Verschleiß. Auf diese Weise ist eine konstruktiv einfache und kostengünstige Absturzsicherung realisierbar. Zusätzliche Stützpfosten, die zwischen den beiden außenliegenden Stützpfosten einer Absturzsicherung angeordnet sind, weisen anstelle der Aufnahmestifte lediglich Ösen auf, durch die jeweils ein Seil hindurchgeführt ist und welche das Seil lediglich in Längsrichtung führen. Jedes Seil ist bevorzugt mittels einer Seilklemme nachspannbar.According to a useful embodiment of the invention, the fall arrest device has at least one rope stretched in the free space between at least two support posts, the rope being pivotably connected to the support posts by means of a cable eye each. In a particularly simple way, this is done by a Realized support post vertically protruding cylindrical receiving pin, which engages in the cable eye and has an external cover plate, the outer diameter of which exceeds the inner diameter of the cable eye and which prevents the cable eye from falling off the receiving pin. The cable eye can be formed by turning over a cable end and fixing it against the cable body by means of cable clamps. The rope eye is preferably reinforced by an inserted thimble. This reduces the friction between the rope and the receiving pin and thus also its wear. In this way, a structurally simple and inexpensive fall protection can be implemented. Additional support posts, which are arranged between the two outer support posts of a fall protection device, instead of the receiving pins only have eyelets through which a rope is passed and which only guide the rope in the longitudinal direction. Each rope can preferably be re-tensioned by means of a rope clamp.
Gemäß einer besonders bevorzugten Weiterentwicklung ist mindestens ein Stützpfosten im Bereich des Fußpunktes mittels einer lösbaren Arretierung gegen ein Verdrehen um das erste Drehgelenk festlegbar. Diese Arretierungseinrichtung kann beispielsweise in Form einer Fußraste ausgeführt sein, welche aus einer ersten Ruheposition durch lineares Verschieben in Richtung auf den Stützpfosten hin in eine zweite, den Stützpfosten gegen ein Verschwenken um dessen erstes Drehgelenk sperrende Eingriffsposition verstellbar ist. Auf diese Weise ist die Absturzsicherung entweder in einer aufgeklappten Arbeitsstellung gegen unbeabsichtigtes Abklappen oder in einer abgeklappten Ruhestellung gegen unbeabsichtigtes Aufrichten gesichert.According to a particularly preferred further development, at least one support post can be fixed in the area of the base point by means of a releasable lock against rotation about the first pivot joint. This locking device can be designed, for example, in the form of a footrest, which can be adjusted from a first rest position by linear displacement in the direction of the support post into a second engagement position that locks the support post against pivoting about its first pivot joint. In this way, the fall protection is secured either in an unfolded working position against unintentional folding down or in a folded down rest position against unintentional erecting.
Die Erfindung erstreckt sich ferner auf ein Fahrzeug mit mindestens einer für den Transport von Kraftfahrzeugen ausgestalteten Ladefläche, deren Lauf- oder Arbeitsbühne eine Absturzsicherung mit mindestens einem der vorgenannten Merkmale aufweist.The invention also extends to a vehicle with at least one loading area designed for the transport of motor vehicles, the walking or working platform of which has a fall protection device with at least one of the aforementioned features.

In
Es versteht sich für den Fachmann von selbst, daß in der Realität die Absturzsicherungen beidseitig zur Fahrzeug-Längsrichtung an der Arbeitsbühne angeordnet sind und beliebige Längserstreckungen bzw. eine beliebige Mehrzahl von Stützpfosten aufweisen können. Im Ausführungsbeispiel handelt es sich um ein Schienenfahrzeug; die Erfindung ist aber in identischer Weise auch auf Straßenfahrzeuge anwendbar. Das Fahrzeug weist eine seitliche Aufstiegshilfe (15) zur Arbeitsbühne (7) auf, welche einer Sprossenleiter ähnelt und von der in
Zur Betätigung der Absturzsicherung ist eine Betätigungsvorrichtung vorgesehen, welche aus zwei miteinander drehgelenkig gekoppelten (20) Teilelementen (18, 19) aufgebaut ist, welche an einem ersten Ende eine drehgelenkige Ankopplung (21) zu der der Aufstiegshilfe nächstliegenden Endstütze (1) und an einem zweiten Ende eine drehgelenkige Ankopplung (22) zum Handlauf (16) der Aufstiegshilfe (15) aufweisen. Die Drehachsen der Drehgelenke (20, 21, 22) sind zueinander parallel ausgerichtet. Das zur Aufstiegshilfe nächstliegende erste Teilelement (18) ist als starrer, angewinkelter Stab ausgeführt; das zur Endstütze nächstliegende zweite Teilelement (19) als Drahtseil, welches in analoger Weise wie die zwischen den Stützpfosten gespannten Seile (13) mittels Seilauge und Kausche in den Drehgelenken (20, 21) gelagert ist. Zum Klappen der Absturzsicherung von einer abgeklappten Ruhe- in die aufgerichtete Arbeitsstellung (bzw. in umgekehrter Richtung) wird das erste stabartige Teilelement (18) rotatorisch um das Drehgelenk (22) bewegt. Dabei wird das Teilelement (18) im Bereich der Gelenkverbindung (20) im Gegenuhrzeigersinn um das Drehgelenk (22) bewegt, d.h. nach oben ausgelenkt. Das zweite Teilelement (19) folgt dieser Bewegung, bis die aufrechte Arbeitsstellung der Absturzsicherung erreicht ist. Mittels eines zusätzlichen Handgriffs am stabartigen ersten Teilelement (18) oder der Endstütze (1) kann die Betätigung der Absturzsicherung durch das Bedienpersonal zusätzlich unterstützt werden. Das Abklappen der Absturzsicherung in die Ruheposition erfolgt in hierzu entgegengesetzter Weise.To actuate the fall protection, an actuating device is provided which is made up of two pivotably coupled (20) sub-elements (18, 19), which at a first end has a pivot coupling (21) to the end support (1) closest to the climbing aid and to one end at the second end a pivot coupling (22) to the handrail (16) of the climbing aid (15). The axes of rotation of the swivel joints (20, 21, 22) are aligned parallel to one another. The first sub-element (18) closest to the climbing aid is designed as a rigid, angled rod; the closest to the end support second sub-element (19) as a wire rope, which is mounted in the swivel joints (20, 21) in a manner analogous to the ropes (13) stretched between the support posts by means of a rope eye and thimble. To fold the fall protection device from a folded down position to the upright working position (or in the opposite direction), the first rod-like sub-element (18) is rotated about the swivel joint (22). The sub-element (18) is moved counterclockwise around the swivel joint (22) in the area of the articulated connection (20), ie deflected upwards. The second sub-element (19) follows this movement until the upright working position of the fall protection device is reached. By means of an additional handle on the rod-like first sub-element (18) or the end support (1), the actuation of the fall protection by the operating personnel can be additionally supported. The fall protection is folded down into the rest position in the opposite way.
