Abstract

The present invention relates substantially to a paying-out device, the drum (4) of which carries a plurality of flexible pipes (5.8) that are wound alongside one another in a manner separated by flanges (42) and are all connected initially to one and the same multi-channel manifold that is fastened to the inside of the drum and can be connected to a central blowing, suction or projection system, notably for shot. The invention also relates to an associated method for suction or blowing or projection over a very long working area.

Abstract

The present invention relates to a robot (1) for renovating and/or inspecting a duct, in particular a penstock. The robot is of the type having a double movement tripod with feet (31 to 33; 41 to 43) in which the movement tracks (34; 44), each one preferably motorised, ensure self-support as well as reliable and accurate movement, even in ducts with a very steep inclination, or vertical ducts, and which is provided with an anti-twisting moving system. The invention likewise relates to the associated method for moving the robot (1).

Abstract

The present invention concerns a bell (9) forming a device that both blasts shot and sucks up the blasted shot, with a casing dedicated to guiding (91) the shot clearly separated from a containment casing (92), which allows very high speed blasting of the shot particles and suction at a very high flow rate, while avoiding the risk of sucking up at least a portion of the shot before it impacts on the surface of the wall to be cleaned. The configurations of the bell according to the invention also allow a high level of productivity to be achieved. The invention more particularly concerns a robot (1) for renovating and/or inspecting a pipe, in particular a pressure pipe, provided with such a bell.
