Definitions

  • the present invention relates to the layout of new technical apparatus and to the arrangement of new workshops thus created.
  • the invention concerns more particularly the equipping of an enclosed site in which maintenance operations, and paint-stripping and paint application operations are carried out.
  • the invention concerns specifically the layout of a site and in particular a hangar which makes possible paint stripping and paint application operations for land vehicles, sea-going craft and aircraft, by means of a stripping agent involving a dry blasting process using one or more blasting nozzles arranged at one or more paint stripping stations which are remote controlled.
  • the invention concerns in particular an installation designed to control stripping and/or painting operations by blasting a stripping agent intended for stripping airframes, by means of nozzles arranged around all the periphery of the immobilized vehicle inside the installation, as well as the stripping and or painting stations and the equipment used.
  • the minimum load of this installation may be 16 aircraft initially, but this can be increased to 50 aircraft which are stripped over 313 working days.
  • the stripping operations can be carried out manually by operatives or by remote-controlled appliances determining the conditions and the parameters of the stripping or painting procedures.
  • the stripping operation is effected by blasting with a dry medium by means of an optimized blasting nozzle, handled by an operative, and supplied with a medium/compressed air mixture by means of a generator.
  • the air/medium mixture delivered to the operative's nozzle is created by a generator made up of a pressurized canister containing a certain quantity of abrasive at utilization pressure and a specific remote-controlled distributor, allowing the desired quantity of medium to pass into the flow of compressed air.
  • the flexible pipe conveys the mixture between this generator and the nozzle, with the minimum of losses and of wear and tear.
  • each blasting nozzle has its own generator, distributor, and supply pipe.
  • blasting conditions can be adjusted for each nozzle depending on the nature of the material to be stripped. These stripping conditions are imposed by the supervisor.
  • the stripping is carried out by blasting using an optimized compressed-air blasting nozzle, handled by an operative provided with protective equipment.
  • the air pressure for blasting can vary from 1.5 to 3.5 bar with a flow rate of 200 to 350 Nm 3 /h, and a medium flow rate from 1 to 3 kg/min.
  • the pipe delivering the mixture of abrasive air has an external diameter of approx. 50 mm.
  • the zones to be treated are not always, or most of the time, accessible at the right height for a man. Their treatment thus necessitates the use of transport carriages or cradles arranged around the craft. These carriages or cradles are mobile, and can if necessary be moved during the stripping phase.
  • the medium is blasted on to the zones to be stripped, and a mixture of reusable medium, used medium and paint and/or stripped off waste falls mainly to the floor of the workshop. Retention zones are thus necessary.
  • the blasting system used is based on the traditional operation of pressure-type compressed air blasting machines.
  • the air/abrasive mixture, delivered to the operative's nozzle, is created by a generator comprising a pressurized canister containing a certain quantity of abrasive at utilization pressure and a distributor allowing the desired quantity of medium to pass into the flow of compressed air.
  • the flexible pipe conveys the mixture between this generator and the nozzle, with the minimum of losses and of wear and tear
  • each blasting nozzle should possess its own generator and feed pipe.
  • the abrasive mixture falling to the ground must be recovered for subsequent reprocessing.
  • Technical-economic optimization of the process necessitates recovery of the medium and separation of the reusable part of the mixture from the waste. Taking into account the specific granular size of the medium, the rate of recovery is about 80%.
  • the medium recovered and the new medium are used to supply the generators.
  • the generators feeding the nozzles are installed permanently, they are necessarily situated at a certain distance from the craft to be treated, the closest being along the partition walls of the workshop. This involves the presence of so many supply pipes for the nozzles on the workshop floor. Apart from the losses of charge and the wear and tear linked with minimal lengths, the nuisance caused by these pipes is considerable: their being heavy to use (tidying away, cleaning and storage), being a hindrance to traffic, difficult for the operatives to handle (weight, time of response, etc . . . )
  • the stripping medium or agent used in the stripping appliance according to the invention is one of those described in the French patent 2,761,365 under the name of the Joint-Trade Organization Biodecap.
  • a vegetable polymer derived from wheat flour, reticulated by a chemical agent is used, which has abrasive properties notably enabling the stripping of aeronautical paintwork systems, while preserving the substrate from any damage.
  • the painting system used for planes, train engines or boats consists of a system formed from a coat of primer and different functional coats (anti-erosion, anti-corrosion).
  • the primer coat is intended to provide cohesion between the substrate and the functional coats.
  • the layout of the technical system according to the invention is in particular formed by a mobile stripping unit, monitored and activated by remote control and comprising:
  • one or more appliances for distributing the stripping material are provided.
  • FIG. 1 shows the structure of a hangar ( 11 ), inside which an aircraft is represented during stripping and reconditioning operations.
  • the layout comprises successively:
  • an inlet for paints A
  • an outlet (B) for paint wastes an inlet for new medium
  • an outlet for the medium wastes D
  • an outflow for new or reprocessed medium E) prior to being directed towards stripping
  • an inlet for the medium after blasting F
  • the lines ( 10 ) represent the computer and power links between the junction boxes and the stripping points. These are flexible links connecting a fixed block and a mobile station whose position is determined by the shape and size of the craft to be reprocessed.
  • the medium After stripping the craft, the medium will be recovered by suction and the other waste will be removed from it by a filtering system. Particular attention will be given to maintaining a sufficient grain-size to allow recycling of the abrasive material.
  • the generators ( 8 ) supplying the nozzles ( 12 ) are installed permanently, being situated at a certain distance from the craft to be processed, the closest being placed along the partition walls of the workshop. This involves the presence of a number of supply lines to the nozzles equal to that of the generators on the hangar floor.
  • the soiled medium falling on the ground is recovered and then recycled. By means of filtering, it is possible to recover up to 80% of the medium used.
  • the medium recovered is mixed with new medium so that it can be used in a new operation.
  • the stock of medium does not have to be large, approximately 50 liters being sufficient to permit continuous blasting without interruption for 20 minutes. It is then necessary to re-supply the compressor's pressurized canister from a supplies store. A few minutes suffice for this operation.
  • each blasting nozzle has its own generating unit mounted on an independent trolley, This trolley, shown in FIG. 2, can be easily moved on the ground and is adjustable in height. It can thus be placed in the best possible position for the zones to be treated and the dimensions of the craft to be stripped.
  • the delivery of the power sources to the trolley ( 23 ) has to be adapted to requirements.
  • the workshop is equipped with buried technical channels or conduits, enabling the passage of necessary flows (compressed air, electricity, etc.) between technical sites (compressors, electrical cabinets) and connection hatches arranged judiciously around the craft to be treated.
  • the stripping trolley ( 23 ) is shown in FIG. 2. This can be moved by an operative and comprises:
  • a generator or pressurized canister ( 17 ) with a capacity of about 50 liters.
  • the supply pressure from this generator is also monitored by the supervisor.
  • a distributing unit ( 18 ) which allows remote control of the medium flow rote notably by means of a jack ( 22 )
  • valves ( 15 ) and ( 15 ′) effecting the medium's isolation from and supply to the generator ( 17 ) from an intermediate open-air hopper ( 14 ) situated over the trolley ( 23 )
  • FIG. 2 shows the mobile trolley ( 23 ) in elevation (FIG. 2A) or from above ( 2 B).
  • the trolley can be moved by a human operative. It is clear that movements could be remote controlled and/or effected by an electric motor.
  • FIG. 2A shows a weighing system ( 16 ) of the generator ( 17 ) viewed in profile (the same weighing system ( 28 , 28 ′, 28 ′′) seen from above is shown in FIG. 2B).
  • a device for distributing the abrasive ( 18 ) is situated at the base and is remote-controlled by means of a mechanical or pneumatic shut-off device ( 22 ). These elements (weighing and shut-off device) enable the supervisor, by means of the automaton, to control the flow rate of the medium, whatever its grain size.
  • FIG. 2B shows the trolley ( 23 ) seen from above, on which the electrical control cabinet ( 26 ), and the access points for maintenance ( 24 ) ( 24 ′) are shown.
  • the supply support in the flexible receptacle ( 13 ) has a capacity of approximately 500 liters. This volume can easily be modified from 200 to 2000 liters.
  • the medium supply support in the flexible receptacle ( 13 ) has a capacity adapted to needs.
  • the layout according to the invention thus comprises an accommodation hangar for craft whose dimensions may vary from 50 to 150 m in length and 10 to 25 m in width.
  • the mobile trolleys used for blasting the medium are 1,500 to 2,000 cm in length, with a height above the ground of between 300 and 500 cm, a flexible receptacle, cylindrical-conical in shape, of 900 to 1,200 cm in height for a diameter of 800 to 1,000 cm.
  • the height of the gantry supporting the distribution system varies from 1,100 to 1,500 cm.
  • the total height of the mobile trolley varies from 2,500 to 3,000 cm.
  • the overall width of the trolley ranges from 1,800 to 2,200 cm.
  • the abrasive flow rate is between 0.5 and 6 kg/min at a pressure of between 1 and 6 bar.
