摘要： The invention relates to a device for pouring out concrete. Said device has a flexible hose (2) attached to a concrete feed line (5), preferably of a concrete pump and having an admission end (6) which is associated with the feed line (5) and through which the concrete conveyed through the feed line (5) enters, and having a discharge end (7) through which the concrete conveyed through the hose (2) emerges from the hose for the purpose of being poured out. The hose (2) is flexible in at least one swivelling plane between a substantially straight starting position and a bent position. Said device also has swivelling means for moving the hose (2) from its starting position to its bent position. To produce a smaller and more simple design of said devices, it is proposed according to the invention that the swivelling means has at least one traction or swelling means (20) which extends at least in the starting position of the hose (2) outside the longitudinal central axis of the hose (2) and at least directly between a first bearing point (10) connected to the hose and associated with one of the discharge ends of the hose, and a second bearing fixed in relation to the admission end and associated therewith. At least one actuation means is provided which is operatively connected to the traction or pressure means in such a manner that the distance between the first and the second bearing points (18) can be reduced, and it is possible to move the hose (2) from the starting position thereof into the bent position thereof.

摘要： A process and device are disclosed for feeding concrete and other thick materials from a container into a feeding pipe by means of two feeding cylinders that can be alternatively connected to the container or to the feeding pipe by a switching device. The feeding pistons of the feeding cylinder alternatively carry out a suction and a compression stroke. The average piston speed during the suction hub is at least temporarily higher than during the compression stroke. In order to achieve a continuous feeding flow, both feeding cylinders are at least temporarily separated from the container, short-circuited together and connected to the feeding line during the switching period tu of the switching device. One of the feeding pistons finishes its compression stroke in this condition and at the same time the other feeding piston starts its compression stroke. The corresponding feeding piston starts its suction stroke only when the short-circuit is again substantially cancelled and only the appropriate feeding cylinder is connected to the container.

摘要： 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).

摘要： The invention relates to a thick matter pump comprising at least pump units (1,2) which alternate between at least two operational mode i.e. a pumping operational mode and a suction operational modes. The pump comprises a pump line, a suction line and a reversing valve which is used to switch between pump units whereby the reversing valve connects a pump unit in a pumping operational mode to the pump line and which connects a pump unit in the suction operational mode to the suction line. The aim of the invention is to improve, the filling level of the pump unit during the suction operational mode. To achieve this, a pressure boosting device (17) is provided in the region of the suction line. Said device operates independently from the pump units in order to actively bring about the compression of thick matter. The pressure boosting device (17) comprises squeezing elements (15, 16) which press the flexible part of the suction line section (10) together.
