Definitions

  • the present invention relates to a service pontoon intended to be used in particular in the context of the maintenance of the banks of tracks or water bodies.
  • Such pontoons equipped with a cutting tool can be used in particular for mowing and / or brushcutting of banks, towpaths and other places difficult to access from the ground, either because of their steep nature or for lack of access for a fairly large brushcutter machine.
  • patent application EP-A-0133324 describes a road service truck intended for cleaning ditches along roads.
  • the truck comprises a platform with a lateral carriage arrangement bucket holder with return movements, the stability of the carriage (whose overhang is low given the short distance from road to ditch) being ensured by four retractable feet each provided with an end pad placed on the road surface.
  • a road service truck is not suitable for bank maintenance, which often requires significant lateral reach for the tool.
  • Patent application DE-A-3,441,452 shows a heavy floating bridge, carrying a central guide track with rails receiving an excavator and two lateral rolling tracks for trucks and other heavy public works vehicles.
  • the floating bridge is mounted across a large body of water (river, lake or canal) to be dredged or deepened.
  • the dimensions of the bridge, in particular its draft, make it unsuitable for work along the banks.
  • the floating bridge is held in place using cables and massive piles driven into the bottom of the body of water and does not have any equipment enabling it to lift its piles and move independently.
  • the object of the invention is to propose an autonomous service pontoon, well suited to working on the bank of a mobile cutting tool permanently requiring precise positioning of the tool, and capable of frequent changes of work station.
  • the invention proposes a self-propelled service pontoon which can be used in particular for the maintenance of the banks of a body of water, characterized in that it comprises a plate provided with a guide track extending longitudinally relative to the pontoon and consisting of two longitudinal rails mounted on the plate in the lateral position, a mobile tool holder assembly carrying a cutting tool and movable on the rails via a displacement carriage longitudinal provided with drive means and two anchor stakes equipped with vertical lifting means.
  • the anchor piles of the pontoon are lowered to be planted in the bottom of the body of water and obtain a fixed and permanent static positioning of the pontoon.
  • the moving part is then moved in a precise manner relative to the pontoon (therefore relative to the bank) to carry out the mowing, brush cutting or cutting operation proper of the bank section using a tool cutting.
  • the piles are raised using their vertical lifting devices and the pontoon is moved to the next section to start the cycle of operations described above.
  • the service pontoon according to the invention is easily maneuverable by a single operator, requiring no mooring on land or on anchor. It can also navigate, including passing the locks thanks to its reduced size.
  • the self-propelled pontoon comprises a steerable rear hydraulic thruster and a hydraulic steerable bow thruster.
  • Such propulsion equipment makes it easier to approach the pontoon relative to the bank, either along the latter (to pass from one section to another) or laterally.
  • each anchoring pile equipped with its vertical lifting means comprises a movable vertical cylindrical tube and a hydraulic lifting cylinder, preferably double-acting, internal to the tube and in axial position relative to the tube.
  • the jack has a body suspended from the end of a bracket secured to the plate and a rod secured to the tube, the movable tube being mounted in a vertical position in a guide well passing through the pontoon.
  • the cylinder used is of the telescopic type.
  • the stem is secured to said plate in a removable manner by means of a sole plate, said sole plate comprising a guide opening for the tube so that the assembly constituted by the stake associated with its stem is movable. individually to facilitate interchangeability or to equip different wells provided on the pontoon.
  • the mounting of the piles through the pontoon is particularly robust, eliminates the lateral growths from the pontoon and reduces the size of the latter.
  • the mobile assembly comprises, in addition to the carriage, a frame on which is mounted an articulated tool-carrying arm, a sliding mechanism extending perpendicular to the guide rails ensuring the connection between the carriage and the frame, the mechanism comprising means for actuating the frame in lateral displacement relative to the plate.
  • the rails have dihedral sliding surfaces on which slide complementary sliding surfaces associated with the carriage with longitudinal displacement. Such an arrangement prevents the risks of the mobile equipment tipping over the rails.
  • a similar anti-tilting arrangement is also provided at the sliding mechanism.

'water; for this purpose the mobile tool holder assembly carries a cutting tool such as a mowing or brush cutter roller.
  • the pontoon is also used for pruning brush growing through bank protection pavers (for example through the cells of seawall pavers) and / or pruning shrubs on the banks.
  • the service pontoon comprises a shell 10 with a flat bottom, the bridge 12 substantially horizontal and generally rectangular in shape defines a platform carrying various pontoon equipment.
