Abstract

The invention relates to a movable surface-cleaning device (1) comprising: a carriage (3) with a nozzle-holder rack, a guide system comprising at least one guide profile (6) on which the carriage (3) with a nozzle-holder rack moves, a flexible pipe (2) for a cleaning fluid supplying the nozzle-holder rack, motorisation means (7) for actuating the carriage with a nozzle-holder rack along the guide profile (6), and pressure-generating means for supplying the flexible pipe (2) with the pressurised fluid. According to the present disclosure, the motorisation means (7) comprise a hydraulic motor which is supplied with pressurised fluid by the pressure-generating means from a first branch, and which is configured to move the carriage with automatic reversal of the direction of rotation of the motor upon hydraulic detection of end-of-travel stops.

Abstract

A device for cleaning surfaces, mobile, in particular for the cleaning of the cooling elements of an exchanger, including a truck for a nozzle-carrier rack, intended to be disposed in a movable manner facing the surface to be cleaned, carrying a nozzle-carrier rack, with one or more nozzles spraying the surface to be cleaned, and a guide system including, on the one hand, at least one guide profile on which the truck for a nozzle-carrier rack moves, acting as a path for the truck during its movement in the direction of the guide profile, and on the other hand, bearing members of the truck moving on the at least one profile, and wherein the at least one guide profile is rigidified by at least one rigidification beam, under elastic tension, rigidly connected in several discrete positions by fastening plates to the guide profile.

Abstract

The invention relates to a motorisation system (1) for a trolley (100) comprising a nozzle rack (101) and a flexible pipe (200) configured to feed the nozzle rack (101), said motorisation system (1) comprising: - a frame (2), - a rotatable motorised roller (3), - a counter-bearing roller (4), - means for driving the motorised roller (3), in which the motorised roller (3) and the counter-bearing roller (4) are configured to drive the movement of said pipe (200) by friction with said pipe (200), said motorisation system (1) further comprising transmission means synchronising the rotation of the motorised roller (3) and the counter-bearing roller (4), and configured so as to ensure direct transmission of torque from the motorised roller (3) to the counter-bearing roller (4).
