Definitions

  • the invention relates to the field of tools used for example in the stuffing of ballast present in particular under railway sleepers.
  • Such tools are in the form of vibrators.
  • These tools further include a heat engine mounted on the body, the engine allowing the generation of a rotation.
  • These tools generally include a body which can be elongated for example, equipped at one end with a member generating vibrations when it is rotated by the motor.
  • These tools are transportable and used by an operator on railway tracks. These tools are provided with a gripping member positioned at the level of the heat engine and designed to facilitate the handling and movement of this tool by the operator.
  • said heat engine Since the heat engine is very stressed during the operation of the tool, said heat engine is most often equipped with an air cooling system. This hot air from the heat engine is exhausted to the outside, most often via a ventilation grille provided in the engine casing. The hot air is exhausted at the top of the engine.
  • the invention aims to remedy all or part of the aforementioned drawbacks.
  • the air leaving the heat engine is evacuated without being re-aspirated by the cooling system of the heat engine because the deflector covers the evacuation region so that the incoming air flow for cooling and the outgoing air flow does not mix, so the incoming air is not heated by the outgoing air flow.
  • the operator is no longer disturbed by the air flow leaving the engine and the vibrator is cooled properly.
  • cover means putting at a certain distance something distinct and separate, in this case the deflector, on a surface or a volume, in this case the evacuation region of heat engine air.
  • the deflector covers only the region of air evacuation.
  • the deflector comprises a first portion forming an air bypass channel, the first portion being shaped to cover the air discharge opening exiting the heat engine so as to channel the air leaving the heat engine in at least one main direction oriented towards the outside of the tool.
  • the first portion of the deflector forms a channel delimiting an air evacuation zone in the form of a half-trunk of a pyramid starting from the motor ventilation grilles up to an outlet of the deflector.
  • the deflector comprises a second portion arranged in the extension of the first portion, said second portion forming an air suction channel extending along at least one side of the heat engine .
  • the second portion is shaped to bring the outside air to the first portion by venturi effect, which makes it possible to draw outside air and bring it into the first portion of the deflector, thereby reducing the temperature of the air from the engine.
  • the deflector according to the invention is a cover having a U-shaped cross section. This form of cover allows the deflector to be adjusted relative to the heat engine in order to channel the outgoing air efficiently.
  • the deflector comprises a first side wall and a second side wall opposite the first wall and an upper wall connecting the first side wall to the second side wall.
  • the upper wall can be curved.
  • the heat engine is housed in a casing on which the deflector is fixed.
  • the first side wall of the deflector is fixed to the casing of the heat engine on one side.
  • the second side wall of the deflector is fixed to the casing of the heat engine on a side opposite to that on which the first side wall is fixed.
  • the tool is a ballast vibrator.
  • tool 1 for ballast tamping is a vibrator.
  • the tool 1 according to the invention comprises a body 2, one end of which 3 is designed to be in contact with the ground and to transmit vibrations to said ground.
  • the tool 1 also comprises a heat engine 4 fixed to the body 2.
  • the heat engine 4 is housed in a casing.
  • the heat engine 4 includes a suction region 4b allowing the entry of incoming air A aspir into the engine thermal for cooling said thermal engine 4.
  • the thermal engine 4 comprises an outlet air outlet region 4a A comes out in which an air outlet opening 5 is formed.
  • the air outlet opening 5 is in the form of a grid comprising a plurality of 'orifices allowing the evacuation of the outgoing air A leaves the heat engine 4.
  • the heat engine 4 is connected to a vibration transmission member 6 cooperating with the body 2 of the tool 1.
  • the tool 1 comprises an air deflector 8.
  • the deflector 8 is positioned above the heat engine 4 and covers the discharge region 4a of the heat engine 4 independently with respect to the other regions of the heat engine and more particularly with respect to the air suction region 4b for the cooling of the heat engine 4, as illustrated in figure 3 .
  • the deflector 8 is fixed to the casing of the heat engine 4 as shown in figure 2 .
  • the deflector 8 comprises a first side wall and a second side wall opposite to the first wall and an upper wall connecting the first side wall to the second side wall.
  • the first side wall of the deflector 8 is fixed to the casing of the heat engine 4 on one side.
  • the second side wall of the deflector 8 is fixed to the casing of the heat engine 4 on a side opposite to that on which the first side wall is fixed.
  • the deflector 8 is a cover having a U-shaped cross section at least on the first portion.
  • the deflector 8 is fixed to the casing of the heat engine 4 by conventional fixing means such as screws.
  • the deflector 8 comprises a first portion 8a forming a first channel designed to guide the outgoing air A comes out generated by the heat engine 4.
  • the outgoing air A comes out is evacuated in at least one main direction in an evacuation zone Z air in the shape of a half pyramid trunk as illustrated in figure 1 distant from the suction region 4b.
  • the outgoing air A out corresponds substantially to the sum of the incoming air A sucked sucked for the engine cooling 4 and heated by the engine 4 and the outside air A ext sucked by venturi effect.
  • the first portion 8a covers the air discharge opening 5 at a distance from the latter so as to form said first channel.
  • the deflector 8 comprises a second portion 8b extending the first portion 8a and extending laterally relative to the casing of the heat engine 4.
  • the second portion 8b is designed to bring outside air A ext to the first portion 8a deflector 8 by venturi effect.
  • the venturi effect is created by the shape of the deflector 8 in the half-trunk of a pyramid, a depression being created by the pressure difference from one end to the other of the deflector 8.
  • the tool 1 also comprises a gripping member 7 designed to allow the operator to guide the vibrator 1 during its use. The operator stands opposite the air exhaust zone Z as illustrated in figure 1 , so as not to be bothered by the air coming out A goes out .
