Definitions

  • the present invention relates to a device for spraying a pressurized fluid and to a surface cleaning machine, in particular for pavements.
  • draining mixes result from the fact that they are made of a porous material.
  • a high pressure water jet is sent to the upper surface of the draining asphalt covering the roadway, which causes the evacuation of fine particles housed in its porosities, particles which are immediately vacuumed after the passage of the high pressure water jet, that is to say before having had time to settle again in the porosity of the mix.
  • Pavement cleaning machines comprise, on the one hand, a device for spraying water at high pressure, and on the other hand, a suction system.
  • the water spraying device mainly comprises a high-pressure water inlet pipe, which is connected, by means of a rotary connector, to a turnstile pivoting around a vertical axis having nozzles directed towards the roadway at its periphery.
  • the turnstile When injecting water at high pressure, the turnstile is rotated by an appropriate means.
  • the rotation of the injection nozzles, combined with the movement of the truck or trolley, ensures the sweeping of the road surface.
  • Water escaping from the sealing parts of the swivel joint can, for example, spread into the bearings of the turnstile and cause loss of efficiency.
  • cleaning surfaces using a pressurized fluid requires the use of a device for projecting the fluid, the maintenance of which is made difficult by the presence of a rotating connector which is highly stressed. by pressure, temperature, or the nature of the fluid.
  • the present invention aims to provide a new device for spraying a pressurized fluid, suitable in particular for surface cleaning machines, comprising nozzles for spraying fluid driven in rotation about a vertical axis, which does not have the drawbacks known devices.
  • the present invention relates to a device for spraying a pressurized fluid
  • a device for spraying a pressurized fluid comprising, on the one hand, a fixed connection opening out to the outside of the device, capable of receiving the end of a pipe for supplying the fluid under pressure, and on the other hand, a member rotating about a vertical axis, provided with at least one fluid projection nozzle, characterized in that said nozzle is mounted freely pivoting about a substantially vertical axis on said rotating member and a flexible pipe directly connects the fixed fitting to the nozzle.
  • the pressurized fluid enters the device through the fixed connector and is conveyed to the projection nozzle by the flexible pipe.
  • the device according to the invention does not present a risk of leakage insofar as it does not comprise any rotary connection.
  • the flexible pipe connects the fixed connector to a turnstile provided with a plurality of nozzles at its periphery and mounted freely pivoting about a substantially vertical axis on the rotating member.
  • the present invention also relates to a machine for cleaning surfaces, in particular roadways, characterized in that it comprises a device as described above.
  • the machine according to the invention can be mounted on the back of a truck or on a manually movable cart.
  • FIG 1 there is shown a truck generally designated by 1, which is provided internally with a water tank, a high pressure pump, and a suction system (not shown).
  • At the rear of the truck 1 is mounted a machine 2 for cleaning pavements.
  • the machine 2 is mounted on the truck 1 using jacks 3 which make it possible to raise it during the movements of the truck and to lower it to the level of the roadway for cleaning the draining asphalt covering the latter.
  • Casters 4 placed on either side of the machine 2 allow, once the machine 2 is lowered, to keep the latter flush with the road, while moving the truck 1 to clean the asphalt draining on a strip substantially corresponding to the length of the truck 1.
  • the machine 2 is hydraulically connected to the truck 1 by a suction pipe 5 and by a high pressure water supply pipe 6.
  • the machine 2 notably comprises a device for spraying water at high pressure according to the invention, which is shown in section in FIG. 2.
  • the high pressure water supply line 6 ends at the upper part of the casing 7 in order to be fixed to a fixed connector 8 secured, for example by screwing, to the upper wall 7 a .
  • a flexible pipe 9 is mounted which is able to withstand the high pressure of the water conveyed by the pipe 6.
  • the lower end of the pipe 9 is connected to a turnstile 10 which is provided with water spray nozzles 11 at its lower part.
  • the turnstile 10 is mounted on a member 12, freely rotating about a vertical axis 13 integral with the lower wall 7b of the casing 7.
  • Ball bearings 14 ensure the free rotation of the member 12 relative to the axis 13.
  • the rotating member 12 is in the form of a disc which has a peripheral groove 15 capable of receiving a drive belt connected to a motor not shown.
  • the turnstile 10 is also mounted idly on the disc 12 by means of ball bearings 16.
  • the lower wall 7b has openings 17 in line with the passage of the water spray nozzles 11.
  • openings 17 allow the passage of water under high pressure which strikes the upper surface of the draining asphalt covering the floor.
  • the axis 13 supporting the disc 12 is held above the ground by the branches 18 cut in the lower wall 7b .
  • the turnstile 10 describes a circle around the axis 13.
  • the flexible pipe 9 is not subjected to any torsional force, because the turnstile 10 is mounted idly on the disc 12, which allows it to keep a constant orientation.
  • the second embodiment of the device of the invention which is shown in FIG. 4, does not include branches 18 to support the axis 13.
  • the lower wall 7 ' b is provided with an orifice, the dimensions of which correspond substantially to those of the disc 12' which comprises a peripheral shoulder 19 in which the groove 15 is produced.
  • Ball bearings 14 ' ensure the free rotation of the disc 12' relative to the wall 7 ' b , around the immaterial axis 13'.
  • This device therefore makes it possible to spray water at very high pressure through rotary nozzles, without having to use any rotary coupling.
