Definitions

  • the invention relates to a device for clamping a removable safety railing on a step of a wagon of a railway transport vehicle.
  • the invention also extends to a secure removable guardrail equipped with a clamping device making it possible to fix the guardrail to a step of a carriage of a railway transport vehicle.
  • a rail transport vehicle such as a freight train, must sometimes carry out a manoeuvre, known as pushback, which aims to cause the train to roll back over a limited distance. These maneuvers are necessary, for example, for terminal services and/or for sorting/relay maneuvers.
  • a pushback maneuver is delicate insofar as the train driver operates blindly.
  • the train driver is assisted by an agent, called shunting agent, who positions himself near the rear of the train and communicates with the driver by radio link or shunting signals.
  • the shunting operator can park on these tracks at a distance from the last wagon and communicate with the driver.
  • the shunting agent tends to park on the step of the rear wagon, despite regulatory prohibitions, which poses problems for his own safety.
  • the train being in motion the shunter is exposed to a risk of falling when he parks on a step without a suitable safety device.
  • Another drawback lies in the time required to mount the maneuvering step on the wagon, which slows down the repression maneuvers in particular.
  • Another drawback also lies in the constraints necessary to ensure this assembly (screwing, bolting, etc.) and in the absence of information relating to the correct assembly of the maneuvering step. In other words, an operator in charge of mounting this step has no means enabling him to guarantee that the fixing is sufficient and therefore to ensure the safety of the maneuvering operator.
  • the inventors have sought to propose an alternative solution to ensure the safety of shunting operators during pushback maneuvers in particular and which can equip a wagon of a rail transport vehicle, without difficulty, and without requiring the replacement of conventional steps.
  • the invention aims to provide a device for clamping a secure removable guardrail on a step of a wagon of a rail transport vehicle, in particular goods.
  • the invention also aims to provide, in at least one embodiment of the invention, a clamping device which can be mounted on a conventional running board without particular difficulties.
  • the invention also aims to provide, in at least one embodiment of the invention, a clamping device which can be mounted on a conventional step without specific tools.
  • the invention also aims to provide, in at least one embodiment of the invention, a clamping device which can be mounted quickly on a step of a wagon of a rail transport vehicle, in particular goods.
  • the invention also aims to provide, in at least one embodiment of the invention, a clamping device which allows the operator to ensure that the latter is properly mounted on the running board of the wagon, in particular by a visual indication of tightening.
  • the invention also aims to provide a secure removable guardrail equipped with a clamping device according to the invention.
  • the invention also aims to provide, in at least one embodiment, a secure removable guardrail that is easily transportable by an operator, and in particular foldable.
  • the invention relates to a device for clamping a secure removable guardrail on a step of a wagon of a rail transport vehicle comprising a horizontal pallet connected to said wagon by a support arm having two substantially opposite faces vertical.
  • the invention therefore relates to a device which makes it possible to clamp a guardrail to a running board of a transport vehicle, this running board comprising a pallet and a pallet support arm having two substantially vertical opposite faces.
  • the invention therefore relates to a device for clamping a guardrail on a specific running board which generally equips freight wagons.
  • the clamping device according to the invention is fixed on the support arm of the pallet of the step, which does not require dismantling the pre-existing step of the wagon to fix the safety guardrail there. No modification of the train is necessary to fix a safety guardrail by means of the clamping device according to the invention.
  • a secure removable guardrail comprises for example a platform (also referred to by the term floor throughout the text) intended to receive the feet of a shunting operator and a guardrail carried by said platform.
  • This guardrail extends in at least one direction, at least at the height of the pool, to prevent the fall of the operator stationed on the floor of the guardrail.
  • the clamping device comprises a frame equipped with means for fixing to the railing. These reinforcement fixing means cooperate with combined means carried by the guardrail, arranged for example opposite the railing. This is particularly suitable for running boards which extend to the rear of wagons, the guardrail then being attached to the support arm so that the guardrail extends towards the rear of the wagon and the shunting operator can park between the rear end of the train, at which the clamping means lock the guardrail on the running board and the guardrail.
  • the guardrail can be hingedly mounted on the floor of the guardrail to facilitate its movement before mounting on the wagon step.
  • the guardrail platform extends above the pallet of the wagon step, and delimits a secure space for a shunting operator who assists a train driver, for example during pushback maneuvers.
  • a clamping device makes it possible to temporarily mount a guardrail on a step of a wagon of a rail transport vehicle.
  • the device according to the invention does not modify the wagon irreparably and can be mounted on the step without difficulty by an operator when necessary.
  • the clamping device also comprises a fixed jaw and a mobile jaw, associated with means for moving this mobile jaw towards the fixed jaw, to ensure clamping of the support arm between the fixed and mobile jaws.
  • These displacement means form, with the fixed and movable jaws, means for clamping the support arm of the step.
  • the clamping device also comprises means for visual control of a predetermined level of tightening of the support arm of the step by the fixed and mobile jaws.
  • This aspect of the invention is particularly useful insofar as it allows an operator to ensure the nominal mounting of the guardrail on the support arm of the step by a simple visual check. In particular, no specific tool is necessary to ensure this assembly and to check its tightening. This saves time while offering increased safety to operators.
  • said frame comprises two parallel upper and lower flanges, spaced apart from each other, and each provided with a plurality of holes for passage of screw elements arranged opposite each other. , and forming said fastening means of said clamping device on said removable guardrail.

  • This conjugate part is for example a strip secured to the platform of the guardrail adapted to be housed between the upper and lower flanges of the frame and comprising passage holes for the fastening elements adapted to be aligned with the openings of the flanges of the armature.
  • said means for moving said movable jaw comprise a rolled screw extending in said longitudinal direction, in helical connection with said armature and mechanically connected to one end of said movable jaw and to the opposite end to a ratchet handle so that a rotation of said ratchet handle causes the longitudinal displacement of said rolled screw and therefore of said movable jaw against the support arm of said step.
  • the mobile jaw comprises for example a semi-ball joint support on which a rubber disk is vulcanized.
  • the movable jaw is linked to the rolled screw by two pins.
  • This rolled screw is mechanically connected to a ratchet handle. An operator can thus actuate the ratchet handle to move the movable jaw towards the support arm of the step and initiate tightening.
