Abstract:
The invention relates to a concrete distributing boom for mobile and stationary concrete pumps. The inventive boom is provided with a substructure (14, 14', 14''), a pillow block (32) that can be rotated around a vertical axis on the substructure and a stack of arms (16) consisting of several mast arms (34, 34', 34'') that can be pivoted against each other. The first mast arm (34) is articulated to a hinge (36) of the pillow block (32). Moreover, a drive mechanism (38) is provided that is provided with a driving pinion (42) for rotatably driving the pillow block (32). Said pinion (42) can preferably be rotated around a vertical axis by means of toothed racks (40). The aim of the invention is to enable to easily change masts between different substructures (14, 14', 14''). The pillow block (32) that is connected to the stack of arms (16) can be detachably coupled to the driving pinion (42) which is arranged in the substructure.
Abstract:
A distributor device, used especially for the distribution of concrete, whereby the length of the concrete delivery pipe can be adapted to a section of the concrete distributing boom that supports said delivery pipe by providingcissor-shaped delivery pipe elements, whereby the pivot points of the delivery pipe elements are crossed in an alternating manner in telescopic end positions and pass in front of each other during the telescoping process between both telescopic end positions. The delivery pipe elements are placed in a respective extended position when in a telescopic end position i.e. in an end position that is opposite to the concrete distributing device and in another end position in the direction of the concrete delivery device.
Abstract:
The invention relates to an auto concrete pump comprising a supporting frame (16) mounted on a chassis (10) and a pump unit (30) disposed on the supporting frame (16) and having a back material feeder container (32). Conveyor pipes or tubes (38, 40) can be connected to the pump unit (30), which can be transported in compartments (42, 44) together with the automatic concrete pump. The compartments can be easily accessed when they are moved from a transport position substantially parallel to the loading area (48, 50) into a removal position tilting downwards in relation to the back end by rotating said compartmens around an axis of rotation (52, 54) parallel to the vertical axis of the chassis and around a tilting axis (56, 58) crosswise in relation to their longitudinal extension and perpendicular to the vertical axis of the chassis. Rotation of the compartments (42, 44) can be done manually or using hydraulic means.
Abstract:
A transfer article (10) has a central portion (12) with elongated rectangular tabs (14 and 16) extending from opposite sides thereof at a linear junction (18, 20) which is bisected by a fold line (22).
Abstract:
An automatic downspout is taught having an extension (20) which swings, in response to passage of water through the downspout, between a storage position and a position for transport of water. The extension (20) has connected thereto a reservoir (22) for retaining an amount of water from the water passing through the downspout. The weight of the water retained by the reservoir (22) acts to maintain the extension (20) in the lowered position for a selected period of time after the passage of water through the downspout stops. An actuator (44) for such an automatic downspout is also taught.
Abstract:
A concrete pumping device has a bearing arm that is cantilevered in its working position and that positions the end (11) of a pumping line (5). The bearing arm (8) has segments (6) that bear each at least one of the pipe segments (4) that compose the pumping line (5). In order to increase the achievable pumping height, at least one of the bearing arm segments (12) may be telescopically extended and can move from a nested initial position into at least one extended position in which the extensible bearing arm segment (12) is longer than the associated pipe segment. At least one device (17) for supplying at least one additional pipe segment (16) can be moved from a first position in which the additional pipe segment (16) is located away from the volume occupied by the pipe segments (4) into a second position in which at least one end section (20) of the additional pipe segment (16) is aligned with at least one end section (21) of a pipe segment (4). The pumping line (15) is essentially made up of the pipe segments (4) and the additional pipe segment (16).
Abstract:
The invention relates to a large manipulator, especially for self-propelled concrete pumps. A chassis bears a mast base rotatable about a vertical pivot (18) and an articulated mast consisting of at least three arms (1 to 5). The arms (1 to 5) can be pivoted to a limited extent about horizontal, mutually parallel axes (A to E) in pairs in relation to the adjacent base (16) or arm (1 to 5) by means of a drive system. The articulated mast is actuated via a remote control device (30) with control levers (34, 34', 34"). In order to ensure a clear allocation of the movements of the control lever (34) and the articulated mast, the invention proposes that the remote control device (30) have a computer-supported co-ordinate transmitter (42) controllable via the control lever (34) for the drive systems (30) via which, in one direction of adjustment (+, -) of the control lever (34), the drive systems (30) for the pivots (A to E) can be actuated independently of the drive system for the pivot (18) of the mast base (16) with the accomplishment of an extending or retracting movement of the articulated mast (20) for a predetermined height (h) of the tip of the mast. In the other direction of adjustment (l, r) of the control lever (34) perpendicular to the first direction, a rotary movement of the articulated mast (20) about the pivot (18) is triggered via the co-ordinate transmitter (42) independently of the movement in the axes (A to E) with a predetermined height (h) of the tip of the articulated mast.
Abstract:
A retractable, concealable peripheric gas station for refuelling in particular military vehicles, which is connected to a main station supplying it both with fuel and hydraulic fluid and includes an outer metal tank (10) closed by an upper cover (11) hinged thereto, a metal frame (14) hinged under said cover so as to pivot between a lowered rest position and a raised operating position, a take-up reel (15) for a hose supplying fuel, and a hydraulic assembly (24) operating between the frame and the tank under control of the oleodynamic main station which causes the frame to pivot between the lowered and raised positions.
Abstract:
A water monitor (100) includes a stationary portion (102) having a fluid inlet (104). A movable portion (106) having a fluid outlet (108) is coupled to the stationary portion (102). A fluid flow path (124) extends between the fluid inlet (104) and the fluid outlet (108) and is configured to communicate fluids (138) from the fluid inlet (104) to the fluid outlet (108). A power transmission (112) is coupled to the movable portion (106) such that the fluid flow path (124) bypasses the power transmission (112). The movable portion (106) is rotatable with respect to the stationary portion (102) to position the fluid outlet (108).
