Title (EN) HYDRAULIC JACKING METHOD AND APPARATUS
(FR) METHODE ET DISPOSITIF DE LEVAGE HYDRAULIQUE
Abstract: front page image
(EN)A hydraulic jacking apparatus (1) comprising an elongated, flexible, inflatable tubular member (2), which is inflatable using air, water and the like, is described. The tubular member (2) is made of material such as that used for making a fire hose. One end of the tubular member is clamped in an air and watertight manner by means of two plate members (3, 4). A hole (6) is provided in the plate members (3, 4) for attaching a line or the like for positioning the tubular member (2) relative to an object to be lifted or moved. In the opposite end of the tubular member there is provided an end cap (7). In the end cap (7) there is provided a pair of quickdisconnect connectors (9, 10) and a bleed valve member (13). The quickdisconnect connectors (9, 10) are adapted to receive a mating connector and comprise internal valve means. The internal valve means is operable to open when the mating connector is connected thereto and to close when the mating connector is disconnected therefrom. The bleed valve (13) is operable for deflating the tubular member (2) independently of the quickdisconnect connectors (9, 10). Hose means (125, 126, 127) is provided for coupling a plurality of the hydraulic jacking apparatus (2) in series and a manifold means (130) is provided for coupling a plurality of the hydraulic jacking apparatus to a manifold depending on the requirements of a particular job. To lift or move an object from the tubular member there is provided a jack show (40, 75) and an extendible pipe member (58, 71). The pipe member has at least one end which is provided for fitting in the jack shoe (40, 75) and a second end (90) adapted to be placed against an object to be moved. The second end (90) may include a pivotable end plate or a spiked or like surface for preventing slippage of the pipe member relative to the object to be moved. In addition, the jack shoe (40) is provided with receptacles (48, 49, 50, 51, 52, 53, 54) for receiving stabilizing pipes for stabilizing the jack shoe (40) during a lifting or moving operation. Plate members (30, 31) are also provided for lashing to the top and bottom of the tubular member (2) of the hydraulic jacking apparatus for protecting the tubular member (2) from damage due to rough and sharp objects.
(FR)Dispositif de levage hydraulique (1) comprenant un element tubulaire (2) allonge, flexible et gonflable a l"air, a l"eau ou a l"aide d"un fluide du meme type. L"element tubulaire (2) est en un materiau tel que celui utilise pour fabriquer un tuyau de lance a incendie. L"element tubulaire est bride a l"une de ses extremites de facon etanche a l"air et a l"eau a l"aide de deux machoires (3, 4). Ces machoires (3, 4) sont percees d"un trou (6) permettant d"attacher une ligne pour positionner l"element tubulaire (2) par rapport a l"objet a lever ou a deplacer. L"extremite oppose de l"element tubulaire est pourvue d"un capuchon (7) qui est lui-meme muni de deux elements (9, 10) a raccordement rapide et d"une vanne de purge (13). Les elements (9, 10) a raccordement rapide sont concus pour s"adapter a des elements de raccord correspondants et comprennent des vannes incorporees qui s"ouvrent lorsque le raccord est ferme et qui se ferment lorsque le raccord est ouvert. La vanne de purge (13) fonctionne pour degonfler l"element tubulaire (2) independamment des elements a raccordement rapide (9, 10). Des tuyaux (125, 126, 127) permettent de brancher en serie une pluralite de dispositifs de levage (2) et un collecteur (130) permet de brancher une pluralite de dispositifs de levage a un meme circuit, selon les besoins de travaux determines. Une embase de cric (40, 75) et un tube extensible (58, 71) permettent le levage ou le deplacement d"un objet a l"aide de l"element tubulaire. Une extremite du tube est concue pour s"ajuster a l"embase (40, 75) et l"autre extremite (90) est concue pour etre placee contre un objet a deplacer. L"extremite (90) peut comporter un plateau pivotant ou une surface garnie de pointes evitant que l"objet a deplacer ne glisse. De plus, l"embase de cric (40) est pourvue de logements (48, 49, 50, 51, 52, 53, 54) recevant des tubes de stabilisation permettant de stabiliser l"embase (40) pendant l"operation de levage ou de deplacement. Des plaques de bridage (30, 31) disposees au dessus et en dessous de l"element tubulaire (2) du dispositif de levage hydraulique protegent ledit element des dommages que pourraient causer les objets rugueux et pointus.
