Abstract:
The invention relates to a large-scale manipulator, especially of concrete pumps. Said large-scale manipulator has a bending mast (22) which consists of at least three mast arms (23 to 27) and which is preferably configured as a concrete spreader mast. The arms of said mast are each pivotable to a limited extent about horizontal, bending axes (28 to 32) which are parallel to each other, by means of a drive aggregate (34 to 38), respectively. A control device (50, 62, 52) for moving the mast with the help of actuating mechanisms that are allocated to the individual drive aggregates, and means for damping mechanical vibrations in the bending mast are also provided.
Abstract:
The invention concerns an assembly comprising balanced loading and unloading arm (14) installed at a first location and having articulated pipeline arms (15, 16) mounted through one of its end on a base (18) and provided at the other of its ends with a system connecting (28) the articulated pipeline arms to coupling means (29) installed at the second location. It further comprises a cable (32) linked through one of its ends to the connecting system (28) and through the other of its ends to means (35-39) adapted to subject said cable to constant tension, and a connecting winch (42) whereon is wound a connection cable (41) for bringing the connecting system (28) in a position to be connected to the coupling means (29).
Abstract:
The device for transmission between a jib comprising at least one pipe section (54a, 54b) fixed to said jib (12) and a coupling section comprises a network of articulated concertina or diamond-shaped articulated pipe sections which can be deformed and are actuated by a cable and at least one pipe section (24a, 24b) joined by coupling. Each section that is fixed to the jib or joined by coupling is joined to one end of the network by means of an elbow and pivoted connections (53a, 53b) whereby the elbow is fixed to a support (51) suspended on the jib. Each end of the network is fixed to a support (74a) which is moveably and rotationally mounted by means of a bearing (78a) on the support of the elbow to which the end is joined in a concentric position with respect to the joint (72a) connecting the end to said elbow. The invention can be used to transfer natural liquefied gas from a platform in the sea to a tanker.
Abstract:
The present invention relates to a faucet (10) which includes a one-piece manifold body (12) and a swivel spout (14) pivotably mounted on the body (12). The body (12) preferably has first and second leg portions (32, 34) for accepting fluid flow therethrough. The faucet (10) may also preferably include an escutcheon (16) coupled to the body (12), a cartridge (30) coupled to the body (12), and a retainer ring (130) interposed between the cartridge (30) and the body (12). In one preferred embodiment, the faucet (10) may include an auxiliary outlet mechanism which may include a diverter valve (118) disposed in the body (12), as well as a hand spray (22) coupled to the body (12) and in fluid communication with the diverter valve (118).
Abstract:
A fluid transfer apparatus for transferring fluids such as hydrocarbon fuel is disclosed. The fluid transfer apparatus comprises a support member and at least one catenary hose, wherein a proximal end of each catenary hose is suspended from the support member. A distal end of each catenary hose is coupled to a transfer manifold. A tensioning member is arranged for applying a tensile force to the transfer manifold during a transfer operation.
Abstract:
A manifold trailer comprises at least one main line having a plurality of discharge connectors and a plurality of articulating arm assemblies which are each connected to a corresponding discharge connector. Each arm assembly comprises a connector member which includes an inlet port, an outlet port and a third port which is located generally opposite the outlet port and is closed by a removable plug member. Each arm assembly also includes an articulating conduit assembly which comprises a first end that is connected to the inlet port and a riser swivel which is connected to the outlet port. During deployment of the arm assembly, a second end of the conduit assembly is connectable to a pumping unit to thereby fluidly connect the pumping unit to the main line.
Abstract:
In one embodiment, a cable extension mechanism includes a housing and a plurality of cable tray segments adapted to retain elongate material therein, wherein each cable tray segment includes first and second cable trays. A sheave is disposed on an axle between the first and second cable trays thereby forming an extendable elbow. At least one wheel assembly is coupled to each cable tray segment to enable the tray segment articulate between a first position wherein the elongate material is stored and has a first length shorter than an actual length of the elongate material and a substantially flat second position, thereby extending a length of the elongate material disposed thereon.
Abstract:
A plug and pump system for routing pressurized fluid from a fluid source is disclosed. The system includes a platform and a docking station interface mounted on the platform and including multiple points of articulation. A wellhead interface is mounted on the platform and includes multiple points of articulation. The docking station interface and the wellhead interface are configured to route pressurized fluid from a fluid source.
Abstract:
A swing spout assembly is disclosed which has a spout having a channel extending from an inlet end to a discharge end. A radially extending groove is formed adjacent the inlet end of the spout, and a snap ring is received in the groove of the spout. A pair of glides in the form of wear washers sandwich the portion of the snap ring extending out of the groove to form a bearing sub-assembly. An escutcheon is positioned around at least part of the inlet end of the spout. A stationary body has a portion that extends into the channel of the spout and a portion extending around an outer radial periphery of the inlet end of the spout. The portion extending around the outer periphery of the inlet end and the escutcheon defining a pocket that retains the bearing sub-assembly.
Abstract:
Die Erfindung betrifft einen Großmanipulator, insbesondere Autobetonpumpe mit einem auf einem Gestell, insbesondere auf einem Fahrgestell (10) angeordneten um eine im Wesentlichen vertikale Drehachse (18) verdrehbaren Mastbock (16), mit einem als Knickmast (20) mit einem von der Mastspitze des Knickmasts aus nach unten hängenden vorzugsweise als Endschlauch (50) ausgebildeten Pendelelement, und mit einer Steuereinrichtung zur Ansteuerungder Antriebsaggregate der Knick- und Drehachsen des Knickmasts, wobei die Fernsteuereinrichtung mindestens einen Neigungsgeber (52, 54) aufweist, der in einem am Pendelelement (50) lösbar befestigten Gehäuse (30) angeordnet ist.
