Definitions
- the invention relates to the field of tools used for example in the tamping of the ballast present in particular under railway sleepers.
- Such tools are in the form of vibrators.
- These tools are transportable and used by an operator on railway tracks. These tools are provided with a gripping member positioned at the heat engine and designed to facilitate the handling and movement of this tool by the operator.
- the object of the invention is to remedy all or some of the aforementioned drawbacks.
- the subject of the invention is a ballast tamping tool comprising:
- the deflector covers the discharge region, said deflector being shaped to channel the air exiting the engine, so that the air exiting the engine is separate and separate from the incoming air for cooling the engine. thermal engine at the engine.
- the air leaving the heat engine is discharged without being re-aspirated by the cooling system of the heat engine because the baffle covers the discharge region so that the air flow entering for cooling and the outgoing air flow does not mix, so the incoming air is not warmed by the outgoing airflow.
- the operator is no longer disturbed by the air flow leaving the engine and the cooling of the vibrator is properly ensured.
- cover means the fact that a separate and separate element, in this case the deflector, is placed on a surface or a volume, in this case the region of air from the engine.
- the baffle covers only the air evacuation region.
- the deflector comprises a first portion forming an air bypass channel, the first portion being shaped to cover the air outlet opening out of the engine so as to channel the air leaving the engine in at least one main direction facing the outside of the tool.
- the first portion of the baffle forms a channel delimiting a pyramidal half-trunk-shaped air evacuation zone from the engine ventilation grids to an outlet mouth 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 engine.
- the second portion is shaped to bring the outside air to the first portion by venturi effect, which allows to suck outside air and bring it into the first portion of the baffle, thus decreasing the temperature of the air leaving the engine.
- the deflector according to the invention is a hood having a U-shaped cross section. This hood shape 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 housing on which the deflector is fixed.
- the first side wall of the baffle is fixed to the casing of the heat engine on one side.
- the tool is a ballast vibrator.
- FIG. 1 is a side view of the tool according to the invention
- FIG. 3 is a top view of the vibrator shown in Figure 1.
- the tool 1 for ballast tamping is a vibrator.
- the tool 1 according to the invention comprises a body 2, one end 3 of which is designed to be in contact with the ground and to transmit vibrations to said ground.
- the tool 1 further comprises a heat engine 4 fixed on the body 2.
- the heat engine 4 is housed in a housing.
- the heat engine 4 comprises a suction region 4b allowing the entry of the incoming air A aS pir in the heat engine for the cooling of said engine 4.
- the heat engine 4 comprises a discharge region 4a exhaust air A sor t in which is formed an air exhaust opening 5.
- the air discharge opening 5 is in the form of a grid having a plurality openings allowing evacuation of the air exiting a sor t of the engine 4.
- the engine 4 is connected to a transmission 6 does orga vibration 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 exhaust region 4a of the heat engine 4 independently from the other regions of the heat engine and more particularly with respect to the suction region 4b of air for the cooling of the heat engine 4, as illustrated in FIG. 3.
- the deflector 8 is fixed on the casing of the heat engine 4 as represented in FIG.
- the deflector 8 includes 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 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 housing of the heat engine 4 on a side opposite to that on which the first side wall is fixed.
- the deflector 8 is a hood having a U-shaped cross section at least on the first portion.
- the deflector 8 is fixed to the ca rter of the heat engine 4 by conventional fastening means such as screws.
- the deflector 8 comprises a first portion 8a forming a first channel adapted to guide the exhaust air A sor t generated by the engine 4.
- the exhaust air A is discharged according sor t at least one main direction in an air evacuation zone Z in the form of a half-truncated pyramid as illustrated in FIG. 1 remote from the suction region 4b.
- the outgoing air A sor t corresponds substantially to the sum of the incoming air Aaspir sucked for the cooling of the heat engine 4 and heated by the heat engine 4 and outside air A ext sucked by the venturi effect.
- the first portion 8a covers the air discharge opening 5 away 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 housing 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 baffle 8 in the half-truncated 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 use. The operator is located opposite to the air discharge area Z as shown in Figure 1, not being obstructed by the exhaust air A sor t
