Die Erfindung betrifft eine Brückenuntersichtvorrichtung mit einem sich über* den Brückenrand nach unten erstreckenden heb- und senkbaren Hubturm, an dem ein unter die Brücke ausladender Arbeitssteg angebracht ist, und mit einem auf der Brücke befindlichen Fahrgestell, das ein in der Arbeitsstellung vertikales Tragelement aufweist, welches mittels über den Brückenrand kragender Arme mit dem Hubtürm verbunden ist.The invention relates to a bridge underside device with a lifting tower that can be raised and lowered over the edge of the bridge and on which a work platform protruding under the bridge is attached, and with a chassis located on the bridge, which has a vertical support element in the working position. which is connected to the lifting tower by means of arms projecting over the bridge edge.
Eine solche Vorrichtung ist beispielweise aus der europäischen O fenlegungsschrif 156 304 bekannt. Als vertikales Tragelement ist dort ein sogenannter Führungstürm beträchtlicher Höhe vorgesehen. Er hat an seiner in der Betriebsstellung zum Brückenrand weisenden Seite Führungsschienen, in denen ein mittels eines Hubzylinders auf und ab verfahrbarer Schlitten geführt ist. An dem Schlitten sind senkrecht zum Führungstürm, d. h. horizontal abstehende Kragarme befestigt, die mit dem Hubturm fest verbunden sind. Die starre Baueinheit aus Hubturm, Kragarmen und Schlitten ist somit-an dem Führungsturm geführt. Die Höhenlage der Kragarme bestimmt die Höhenlage des Arbeitsstegs.Such a device is known, for example, from European Offenlegungsschrift 156 304. A so-called guide tower of considerable height is provided as the vertical support element. On its side facing the edge of the bridge in the operating position, it has guide rails in which a carriage which can be moved up and down by means of a lifting cylinder is guided. On the carriage are perpendicular to the guide tower, i.e. H. horizontally projecting cantilever arms attached, which are firmly connected to the lifting tower. The rigid structural unit consisting of the lifting tower, cantilever arms and slide is thus guided on the guide tower. The height of the cantilever arms determines the height of the work platform.
Häufig ist es erforderlich, mit den Kragarmen am Brückenrand angeordnete hohe Hindernisse, wie z. B. Schutzzäune, Schallschutzwände oder Laternenmasten, zu übergreifen. Mit einem ausreichend hohen Führungsturm ist dies zwar möglich, jedoch kann der Hubtürm dann nicht mehr in Höhenrichtung bewegt werden, um den Arbeitssteg in den richtigen Abstand zur Unterseite des Brückentragwerks zu bringen. Ein weiteres Problem stellt sich im Zusammenhang mit sogenannten Fachwerkbrücken, deren zu beiden Seiten der Fahrbahn befindliche Träger aus einander abwechselnden vertikalen Säulen und schrägen Streben bestehen, die oben durch horizontale Binder miteinander verbunden sind. Hier ist man gezwungen, mit den Kragarmen durch die aus Säule, Strebe und Binder gebildeten Fenster zu greifen, und zwar über oder unter der schrägen Strebe. Dies erzwingt in Abhängigkeit von dem Verlauf des Fachwerks an verschiedenen Standorten längs der Brücke unterschiedliche Höhen des Arbeitsstegs, was nicht hingenommen werden kann.Often it is necessary to use the cantilever arms to arrange high obstacles, e.g. B. protective fences, soundproof walls or lampposts. This is possible with a sufficiently high guide tower, but the lifting tower can then no longer be moved in the vertical direction in order to bring the work platform at the correct distance from the underside of the bridge structure. Another problem arises in connection with so-called truss bridges, the beams on either side of which consist of alternating vertical columns and oblique struts that are connected to one another by horizontal trusses. Here one is forced to reach with the cantilever arms through the windows formed from the column, strut and truss, above or below the oblique strut. Depending on the course of the truss at different locations along the bridge, this forces different heights of the work platform, which cannot be tolerated.
Der Erfindung liegt die Aufgabe zugrunde, eine selbstaufbauende Brückenuntersichtvorrichtung vorzuschlagen, welche hohe Hindernisse am Brückenrand und schräge Fachwerkstreben übergreift und trotzdem ein Verändern der Höhe des Arbeitssteges zuläßt, sowie einfach konstruiert und leicht zu bedienen ist.The invention is based on the object of proposing a self-assembling bridge underside device which overlaps high obstacles at the bridge edge and oblique truss struts and nevertheless permits a change in the height of the work platform, and is simple in construction and easy to use.
Diese Aufgabe wird bei einer gattungsgemäßen Brückenuntersichtvorrichtung erfindungsgemäß dadurch gelöst, daß der Hubturm von einem Führungsorgan aufgenommen und bezüglich dessen in Turmlängsrichtung verfahrbar ist und daß die Arme einenends an dem Tragelement und anderenends an dem Führungsorgan horizontalachsig angelenkt sind und ein Doppelparallelogramm bilden, und daß sich die Arme bezüglich einer zum Hubturm senkrechten Mittelstellung nach beiden Seiten ausschwenken lassen.This object is achieved according to the invention in a generic bridge underside device in that the lifting tower is received by a guide member and can be moved in the longitudinal direction of the tower with respect to it, and that the arms are articulated at one end on the support element and at the other end on the guide member and form a double parallelogram, and that the Let the arms swing out to both sides with respect to a central position perpendicular to the lifting tower.
Anstelle eines Führungsturms ist ein verhältnismäßig niedriges Tragelement in Gestalt eines im wesentlichen rechteckigen Rahmens vorgesehen, an dem insgesamt mindestens vier zueinander parallele Arme unmittelbar angelenkt sind. Auf der Hubturmseite sind die Arme an einem Führungsorgan angelenkt, an dem der Hubt rm hohenverfahrbar geführt ist. Die Arme sind vorzugsweise s lang, daß zwischen den nach unten und oben ausgelenkten Endstellungen des Führungsorgans ein Höhenunterschied von wenigstens etwa 1,5 m erreicht werden kann.Instead of a guide tower, a relatively low support element in the form of an essentially rectangular frame is provided, on the whole at least four arms parallel to one another are articulated directly. On the lifting tower side, the arms are articulated on a guide element on which the lifting tower is guided so that it can be moved high. The arms are preferably s long so that a height difference of at least approximately 1.5 m can be achieved between the end positions of the guide element which are deflected downwards and upwards.
Somit läßt sich die Höhenlage des Hubturmes und des von ihm getragenen Arbeitssteges durch zwei voneinander unabhängige Mittel verändern, nämlich einerseits durch Verfahren des Hubturms bezüglich des Führungsorgans und andererseits durch Hoch- und Herabschwenken der Arme. Diese doppelte Hohenverstellbarkeit ermöglicht den Einsat der Vorrichtung bei Fachwerkbrücken, denn wenn die Arme nach unten geschwenkt werden müssen, kann der Hubturm entsprechend hochfahren und umgekehrt.The height of the lifting tower and the work platform carried by it can thus be changed by two mutually independent means, namely on the one hand by moving the lifting tower with respect to the guide member and on the other hand by swinging the arms up and down. This double height adjustment enables the device to be used on truss bridges, because if the arms have to be swung down, the lifting tower can be raised accordingly and vice versa.
Da sich die Höhen-Verstellbereiche addieren, kann der Verstellbereich des Hubturms bezüglich des Führun sorgans verhältnismäßig klein sein, so daß mit erheblichem Kostenvorteil anstelle eines Teleskopzylinders ein einfacher Hubzylinder verwendet werden kann.Since the height adjustment ranges add up, the adjustment range of the lifting tower with respect to the guide can be relatively small, so that a simple lifting cylinder can be used with a considerable cost advantage instead of a telescopic cylinder.
Vorzugsweise ist das von den Armen gebildete Doppelparallelogramm mittels wenigstens eines schräg an den Armen oder am Führungsorgan einerseits und am Tragelement andererseits angreifenden Hubzylinders betätigbar.The double parallelogram formed by the arms can preferably be actuated by means of at least one lifting cylinder acting obliquely on the arms or on the guide element on the one hand and on the support element on the other hand.
Zum Aufstellen ist es vorteilhaft, wenn das Fahrgestell einen um eine vertikale Achse schwenkbaren Drehtisch aufweist und das Tragelement an diesem um eine horizontal Achse schwenkbar und einstellbar gelagert ist. Durch ein geringfügiges Verändern der Winkelstellung des Tragelements läßt sich eine eventuelle Querneigung der Fahrbahn ausgleichen oder auch eine durch ein Bankett o. dgl. verursachte Seitenneigung des Fahrgestells zur Fahrbahn.To set it up, it is advantageous if the chassis has a turntable that can be pivoted about a vertical axis and the support element is pivotably and adjustably mounted thereon about a horizontal axis. A slight change in the angular position of the support element allows a possible transverse inclination of the Compensate the roadway or a side inclination of the chassis to the roadway caused by a banquet or the like.
Um bei Bedarf besonders breite Barrieren am Brückenrand übergreifen zu können und beim Auf- und Abschwenken der Arme noch größere Höhenunterschiede des Führungsorgans zu erzielen, können die Arme längenveränderbar ausgebildet sein.In order to be able to reach over particularly wide barriers at the bridge edge if necessary and to achieve even greater height differences of the guide member when the arms are pivoted up and down, the arms can be designed to be variable in length.
Die Schwenkbarkeit der Arme hat auch den Vorteil, daß die Transporthδhe, d. h. die Höhe der für den Straßentransport auf ein Fahrzeug verladenen Brückenuntersichtvorrichtung, klein gehalten werden kann. In diesem Fall befindet sich das Tragelement in horizontaler Lage und der Hubturm mit dem Führungsorgan parallel darüber. Durch eine Neigung der Arme kann somit der Hubtürm abgesenkt und die Gesamthöhe verringert werden.The pivotability of the arms also has the advantage that the transport height, i.e. H. the height of the bridge inspection device loaded onto a vehicle for road transport can be kept small. In this case, the support element is in a horizontal position and the lifting tower with the guide element is parallel above it. By tilting the arms, the lifting tower can be lowered and the overall height reduced.
Die beschriebene Vorrichtung erlaubt einen besonders bequemen und sicheren Zustieg vom Fahrgestell zum Hubturm, indem die beiden unteren Arme durch einen Boden miteinander verbunden werden. Der Abstand zwischen diesem Boden und den oberen Armen, die miteinander quer verstrebt sind, kann z. B. 2 m betragen, so daß man auf der überstiegsbrücke aufrecht gehen kann. Seitlich können gelenkige Geländerstäbe angebracht sein.The device described allows a particularly convenient and safe approach from the chassis to the lifting tower, in that the two lower arms are connected to one another by a floor. The distance between this floor and the upper arms, which are braced transversely to one another, can e.g. B. 2 m, so that you can walk upright on the bridge. Articulated balusters can be attached to the side.
Um in Einzelfällen noch einmal an Höhe zum übergreifen von Schallschutzwänden o. dgl. zu gewinnen, ist es zweckmäßig, wenn die unteren Arme am Tragelement und am Führungsorgan wahlweise in höher angeordnete Gelenkaugen versetzbar sind. Die gewonnene Höhe verringert allerdings die Stehhöhe auf der überstiegsbrücke. Dem kann durch eine Verlängerung des Tragelements und durch eine V-förmige Anordnung der Querstreben zwischen den oberen Armen begegnet werden. Eine solche V-Anordnung verringert die Gefahr des Anstoßens mit dem Kopf.In order to gain additional height in individual cases for gripping over soundproof walls or the like, it is expedient if the lower arms on the support element and on the guide element can optionally be displaced into articulated eyes arranged higher. However, the height gained reduces the headroom on the bridge. That can be done by a Extension of the support element and be countered by a V-shaped arrangement of the cross struts between the upper arms. Such a V arrangement reduces the risk of head bumping.
Die beschriebene Brückenuntersichtvorrichtung ist außergewöhnlich flexibel im Einsatz. Sie läßt sich auch aufstellen, wenn der Raum über der Fahrbahn beispielsweise bei Autobahnkreuzungsbauwe'rken durch eine weitere überkreuzende Fahrbahn beschränkt ist. Es lassen sich hohe Hindernisse am Fahrbahnrad übergreifen, ohne daß dadurch die Höhenbeweglichkeit des Arbeitsstegs beeinträchtigt ist. Andererseits reicht der Hubturm, wenn die Arme nach unten geneigt sind, außerordentlich tief unter die Brücke, so daß auch sehr hohe Brückentragwerke vom Arbeltssteg aus von unten besichtigt werden können.The bridge underside device described is exceptionally flexible in use. It can also be set up if the space above the carriageway, for example in the case of motorway intersection structures, is limited by a further crossing carriageway. It can overlap high obstacles on the road wheel without affecting the height of the work platform. On the other hand, when the arms are inclined downwards, the lifting tower extends extremely deep under the bridge, so that even very high bridge structures can be viewed from below from the Arbeltssteg.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Im einzelnen zeigtAn embodiment of the invention is explained below with reference to the drawing. In detail shows

Fig. 2 die Draufsicht der Vorrichtung nach Fig. 1.FIG. 2 shows the top view of the device according to FIG. 1.
Die Brücke 1 hat im Beispiel ein Geländer 2. Als Fahrgestell dient ein LKW 3, der einen um eine vertikale Achse 4 drehbaren Drehschemel 5 aufweist. An diesem ist mit horizontaler Achse 6 ein Tragelement 7 schwenkbar gelagert, welches als viereckiger Rahmen ausgebildet ist, durch den das Bedienungspersonal in den Hubturm 8 übersteigen kann. Mittels eines Hubzylinders 9 , der bei 10 am Tragelement 7 angelenkt ist, wird das Tragelement 7 von seiner horizontalen Transportstellung, in welcher es auf dem Drehschemel 5 aufliegt, in die gezeigte vertikale Arbeitsstellung geschwenkt.In the example, the bridge 1 has a railing 2. A truck 3, which has a turntable 5 that can be rotated about a vertical axis 4, serves as the chassis. On this with a horizontal axis 6, a support element 7 is pivotally mounted, which is designed as a square frame through which the operating personnel can climb into the lifting tower 8. By means of a lifting cylinder 9, which is articulated at 10 on the support element 7, the support element 7 of its horizontal transport position, in which it rests on the turntable 5, pivoted into the vertical working position shown.
An dem Tragelement 7 sind Arme 11, 12 angelenkt, die als Doppelarme oder Rahmen (in der Seitenansicht nicht sichtbar) ausgebildet sind. Mit ihren linken Enden sind die Arme 11, 12 an einem Führungsorgan 13 angelenkt. Die jeweils horizontalen Gelenkachsen des oberen Armes 11 sind mit 14 und 15 und diejenigen des unteren Armes 12 mit 16 und 17 bezeichnet. Zur Betätigung der Arme bzw. des von ihnen gebildeten Doppelparallelogramms dienen zwei Hubzylinder 18 die bei 19 und 20, d. h. oben am Führungsorgan und knapp unterhalb der Mitte des Tragelements angelenkt sind. Der Führungsturm 8, an dessen unterem drehbaren Teil ein Arbeitssteg angebracht ist, ist nur mit seinem oberen Teil dargestellt. Seine beiden der Brücke 1 benachbarten Eckholme 21 sind verstärkt und als Führungsschienen ausgebildet, in welchen die Rollen 22 oder entsprechende Gleitelemente des Führungsorgans 13 sich entlangbewegen können. Der Hubzylinder, welcher den Hubturm bezüglich des Führun sorgans bewegt, ist nicht dargestellt.Arms 11, 12, which are designed as double arms or frames (not visible in the side view), are articulated on the support element 7. The arms 11, 12 are articulated to a guide member 13 with their left ends. The respective horizontal joint axes of the upper arm 11 are denoted by 14 and 15 and those of the lower arm 12 by 16 and 17. To actuate the arms or the double parallelogram formed by them serve two lifting cylinders 18 which at 19 and 20, d. H. are articulated at the top of the guide element and just below the center of the support element. The guide tower 8, on the lower rotatable part of which a work platform is attached, is only shown with its upper part. Its two corner posts 21 adjacent to the bridge 1 are reinforced and designed as guide rails in which the rollers 22 or corresponding sliding elements of the guide member 13 can move along. The lifting cylinder, which moves the lifting tower with respect to the guide, is not shown.
Aus der Draufsicht nach Fig. 2 ist insbesondere die gegenseitige Verstrebung der beiden oberen Arme 11 erkennbar, nämlich eine Querstrebe 23 und je zwei V-förmig angeordnete Streben 24. Die vertikalen Holme des Tragelements 7 sind oben durch ein Querhaupt 25 miteinander verbunden. Auch das Führungsorgan 13 ist zweischenklig ausgebildet und quer verstrebt. Der Drehschemel 5 ist in der Draufsicht nur bruchstückhaft gezeigt. Wird der Hubzylinder 18 ausgefahren, so schwenken die Arme 11 und 12 nach oben und entsprechend nach unten, wenn der Hubzylinder 18 ganz eingefahren wird. Diese Endstellungen sind jeweils strichpunktiert angedeutet. Bei dieser Schwenkbewegung verändert sich vorteilhafterweise nicht nur die Höhe des Führungsorgans 13 und des von ihm getragenen Hubturms, sondern auch dessen Abstand von der Brücke. Eine Querneigung der Brückenoberfläche kann durch Nachstellen des Hubzylinders 9 ausgeglichen werden, d. h. der Hubturm steht auch in einem solchen Fall vertikal.The plan view according to FIG. 2 shows in particular the mutual bracing of the two upper arms 11, namely a transverse strut 23 and two struts 24 arranged in a V-shape. The vertical bars of the support element 7 are connected to one another at the top by a crosshead 25. The guide member 13 is also formed with two legs and braced transversely. The turntable 5 is only partially shown in plan view. If the lifting cylinder 18 is extended, the arms 11 and 12 pivot upwards and downwards accordingly when the lifting cylinder 18 is fully retracted. These end positions are indicated by dash-dotted lines. This pivoting movement advantageously changes not only the height of the guide member 13 and the lifting tower carried by it, but also its distance from the bridge. A transverse inclination of the bridge surface can be compensated for by adjusting the lifting cylinder 9, ie the lifting tower is also vertical in such a case.
Ausgehend von der gezeigten Betriebsstellung erfolgt der Abbau der Vorrichtung in die Transportstellung wie folgt: Zunächst wird der nicht gezeigte Arbeitssteg nach außen geschwenkt und dann an den Hubturm herangeklappt. Der Hubturm 8 fährt dann auf etwa halbe Höhe hoch, d. h. etwa in seine Gleichgewichtslage bezüglich der Arme 11 und 12. Jetzt klappt das Tragelement 7 mittels Einziehens des Hubzylinders 9 auf das Fahrzeug; die Arme 11 und 12 stehen in ihrer Mittellage rechtwinklig zum Tragelement 7 und zum Hubturm 8. Infolge der Schwenkbewegung des Tragelements 7 hebt sich der Turm und schwenkt mit seinem unteren Ende von der Brücke weg und mit dem oberen Ende auf die Brücke herein. Schon während der Schwenkbewegung beginnt der Drehschemel 5 sich zu drehen, wobei das obere Hubturmende immer noch eine Höhe von etwa vier Meter über der Fahrbahn hat, so daß auf der neben dem LKW 3 verlaufenden Fahrspur die Fahrzeuge darunter durchfahren können. Nach Erreichen der Parallelstellung zum Fahrzeug werden die Arme 11 und 12 leicht geschwenkt und das Führungsorgan 13 dadurch etwas abgesenkt. Der Hubturm 8 ruht jetzt auf festen Halterungen auf dem Fahrerhausdach und an der Heckseite des Fahrzeugs. Es ist als besonderer Vorteil der beschriebenen Vorrichtung anzusehen, daß die durch Verschwenken der Arme 11 und 12 erreichbare Hubbewegung nur durch Ansteuern der Hubzylinder 18 in exakt vertikaler Richtung erfolgt. Der Zustieg zum Hubturm 8 ist unproblematisch. Der Arm 12 dient dabei als Brücke oder Rampe, die auch in Schräglage ohne weiteres begangen werden kann, wenn ein entsprechend griffestes Gitter verwendet wird. Bei noch größeren Neigungen kann auch eine Treppe mit Schwenkstufen verwendet werden.Starting from the operating position shown, the device is dismantled into the transport position as follows: First, the work platform, not shown, is pivoted outwards and then folded up onto the lifting tower. The lifting tower 8 then rises to approximately half the height, ie approximately in its equilibrium position with respect to the arms 11 and 12. Now the support element 7 folds onto the vehicle by retracting the lifting cylinder 9; the arms 11 and 12 are in their central position at right angles to the support element 7 and to the lifting tower 8. As a result of the pivoting movement of the support element 7, the tower lifts and swivels away from the bridge with its lower end and into the bridge with the upper end. The turntable 5 already begins to turn during the swiveling movement, the upper end of the lifting tower still being approximately four meters above the roadway, so that the vehicles beneath it can pass through on the lane 3 running next to the truck. After reaching the parallel position to the vehicle, the arms 11 and 12 are pivoted slightly and the guide member 13 is thereby somewhat lowered. The lifting tower 8 now rests on fixed supports on the cab roof and on the rear of the vehicle. It is to be regarded as a particular advantage of the device described that the lifting movement which can be achieved by pivoting the arms 11 and 12 takes place only by actuating the lifting cylinders 18 in the exactly vertical direction. The approach to the lifting tower 8 is unproblematic. The arm 12 serves as a bridge or ramp, which can also be easily walked in an inclined position if an appropriately grippable grid is used. For even larger inclinations, stairs with swivel steps can also be used.
Durch die Verkürzung und Verkleinerung des Tragelements 7 im Vergleich zu dem bekannten Hubturm wird in der Transportstellung vor und hinter dem Tragelement und den Armen 11 und 12 auf der Ladebene des Fahrzeugs erheblich an Platz gewonnen. Insbesondere ist es möglich, an diesen Stellen Kabinen einzubauen, welche dem an der Brücke arbeitenden Personal während der Arbeiten als Aufenthaltsräume dienen können. By shortening and reducing the size of the support element 7 compared to the known lifting tower, considerable space is gained in the transport position in front of and behind the support element and the arms 11 and 12 on the loading level of the vehicle. In particular, it is possible to install cabins at these locations, which can be used as recreation rooms for the personnel working on the bridge during the work.
