摘要:
A marine fall pipe system is constructed for placing rock on a sea bed. The fall pipe system comprises a substantially tubular fall pipe, wherein the fall pipe system comprises buoyancy provided such as to, during use, be arranged along the fall pipe so as to at least partially compensate for a weight of the fall pipe system. The buoyancy is preferably provided such as to, during use, being distributed along the fall pipe. The fall pipe system comprises substantially tubular fall pipe sections for making up the fall pipe, the buoyancy being associated with one or more fall pipe sections, and the one or more fall pipe sections with associated buoyancy comprise integral buoyancy. The buoyancy is provided by microspheres integrated in the fall pipe section(s), the microspheres comprising hollow microspheres, especially hollow glass microspheres. The fall pipe sections may comprise bottomless buckets having a top side and a bottom side, an external perimeter of the bottom side being smaller than an internal perimeter of the top side, a top side of one fall pipe section overlapping a bottom side of an adjacent fall pipe section.

The telescopic chute assembly may be used to discharge cement from a discharge end of a concrete mixer mounted on a truck. The chute assembly has several telescopic chute sections for receiving the material from the mixer. The chute sections have a plurality of aligned flat strips that are attached to one another at an angle to form an elongate trough-shaped body to reduce the friction between the cement and the chute sections.

Un couloir de déchargement télescopique linéaire et extensible (10) peut être monté de manière pivotante sur un camion (12). Le couloir (10) comprend une première partie (40) de couloir et une multiplicité de parties de couloir mobiles télescopiques (74, 76) formées de cadres ouverts (78) ayant des revêtements amobiles (86) fixés à la base à l'intérieur de chaque cadre ouvert (78). Des rails de guidage et de support (70, 84) reliant de manière mobile une partie de couloir à une autre sont aussi aisément amovibles desdites parties (40, 74, 76) pour être facilement remplacés lorsqu'ils sont usés. Le mouvement vers l'intérieur et vers l'extérieur de chaque section (40, 74, 76) par rapport à l'autre est commandé mécaniquement par l'utilisation de plusieurs béliers hydrauliques (94 ou 133) à double action, qui évitent ainsi la nécessité d'utiliser de long tuyaux hydrauliques flexibles. Les béliers hydrauliques (94 ou 133) et d'autres dispositifs de commande mécanique (29, 36) utilisés pour déplacer le couloir (10) vers le haut ou vers le bas ou à gauche et à droite, sont commandés par un élément de commutation à distance (18 ou 148) pour permettre à un opérateur de commander le mouvement mécanique du couloir télescopique (10) alors qu' l se trouve auprès de l'extrémité de déchargement (16) du couloir (10).
摘要:
A marine fall pipe system (100) for placing blocks of stone and/or rock(R) on a sea bed (SB) is configured for suspension from a marine vessel (10). The fall pipe system comprises substantially tubular fall pipe segments (110) configurable to provide at least first and second fall pipe sections (101, 102) of fall pipe segments,and a suspension module (200) configured to be suspended from the marine vessel. The suspension module is configured for suspending the second fall pipe section (102) of fall pipe segments from the suspension module so as to continue the first fall pipe section (101) of fall pipe segments. The first fall pipe section (101) and the suspension module (200) with the second fall pipe section (102) are independently suspended from the marine vessel (10). The suspension module (200) may be configured for suspension by at least one chain, cable (220) or wire.
摘要:
The invention relates to a transport device comprising a filling device (7) enabling the vertical flow of powdery media having different particle sizes and particle densities, without demixing. Said transport device is characterised by the following elements: a reservoir (8) comprising a lower opening (9) to which the filling device (7) can be coupled; a feeding hopper (1) comprising an upper feeding opening (10) and a lower discharge opening (11) of a funnel tube (12), the feeding opening (10) being couplable to the lower opening (9) of the reservoir (8); and telescope elements (13) which are arranged on the funnel tube (12) and carry a discharging hopper (3) provided with a discharge flap (4).
摘要:
A discharge chute especially for use in connection with a concrete carrying mixer, such as a rotating container or a like mounted on the chassis of a truck. The discharge chute (1) includes at least two substantially overlapping chute sections (1a, 1b, 1c) movable relative to each other in the longitudinal direction (s) of discharge chute (1) preferably by means of hydraulic drive mechanisms or the like. Each chute section (1a, 1b, 1c) includes an intermediate portion (a), comprising a discharge through, and edge portions (b) which are fitted with a slide-support assembly for enabling the relative movement of overlapping chute sections and for bracing the same together. The edge portions (b', b') of chute sections (1a, 1b, 1c) of discharge chute (1) are essentially identically shaped in cross section and thus adapted to be overlapped on each other and, thus, being spaced a distance from each other, essentially form said slide-support assembly.

The invention relates to a vessel provided with tubular means descending from or beside the vessel, said tubular means being intended for depositing material therethrough on the underwater bottom surface. Driving means (6) are provided near the bottom end of said tubular means, by which the end of the tubular means is movable transversely to the longitudinal axis of the tubular means. Along at least most of its length the tubular means is built up of a number of shells (7) arranged one above the other, whose upper sides and bottom sides are open, said shells slightly tapering off toward the bottom, whereby the upper end of a shell overlaps the bottom end of a shell located therebelow, while forming an open gap between said overlapping shell ends. Each shell is connected, by flexible connecting means (9), to the shell located directly therebelow.
摘要:
A concrete mixer truck in which the vehicle chassis is provided with a framework (2) which supports a rotary drum (3) in which, in use, a concrete mixture is prepared and transported. The drum (3) is provided with a discharge opening (5) and an underlying discharge duct (6) arranged to allow the transfer of the concrete mixture from the drum'(3) to the place of use. The discharge duct (6) has an axial length which is continuously variable between predetermined minimum and maximum values. Manually operable control means (70, 17, 18), when operated, cause a variation in the axial length of the said duct (6). Further control means (71; 42; 53) are arranged to rotate the duct (6) about a vertical axis and about a horizontal axis.
