Definitions

  • the present invention relates to a lifting device for a mobile stopper in a railway, tramway or metro vehicle, thereby allowing easy access to the space between two vehicles.
  • the invention also relates to the coupling and to the railway vehicle comprising such a lifting device with a movable stopper.
  • the mechanical coupling device consists of head crosspieces on which are bolted bumpers and comprising traction hooks with screw tensioners.
  • the mechanical coupling device When coupling railway vehicles, the two stops of each vehicle are attached to each other and compressed in order to absorb the compression forces (shock members), while screw tensioners connected to the hooks traction allow to absorb the traction forces.
  • the operator When coupling two vehicles, the operator must indeed be positioned inside this Berne square in order to connect the screw tensioner of the first vehicle to the traction hook of the second vehicle, as well as to connect the brake hoses of the two vehicles and to open the taps 'stop.
  • railways generally use automatic couplings which are capable of transmitting traction but also compression forces. This avoids having bumpers interfering with the coupling and decoupling operation.
  • Unfortunately there is a compatibility problem, because generally each country uses a specific model, and even the large families of automatic couplings are only very rarely compatible with each other (example Willison coupling family). Consequently, in Europe, the installation of automatic couplings on the whole of the railway fleet would represent a substantial investment.
  • the document DE19549277 discloses a wagon whose cross members supporting the buffers are movable.
  • the crosspieces pivot laterally, around a vertical axis.
  • the document DE3815693 discloses a rail vehicle floor, with a cross member pivoting both laterally and axially.
  • the document DE4241395 describes a system for lowering bumpers on a low-bed wagon to facilitate the approach of the wagon to the loading dock.
  • the document FR1298268 describes a railway freight car with a lowered loading platform.
  • the head beams of the wagons must be raised relative to the platform.
  • the stops are movable, up or down, via a pantograph system.
  • the present invention aims to provide a solution to facilitate operator access to the coupling and connection devices of two rail vehicles.
  • Another object pursued by the invention is to provide a solution at a reasonable price making it possible to reduce the number of accidents during the coupling / uncoupling of railway vehicles.
  • Another object further pursued by the invention is to provide a device making it possible to increase productivity and reduce the cost of the operations of hooking / unhooking locomotives and wagons, which are very numerous in one day at a marshalling yard or an industrial site.
  • Another aspect of the present invention relates to a railway vehicle comprising a head crossmember to which the lifting device for a mobile stopper is connected as described above, with pneumatic supplies connected to supply the lifting device, as well as brake hoses and a hook and screw tensioner system for coupling with another railway vehicle.
  • the rail vehicle is a locomotive, a wagon, a car, a van, a draisine or a construction machine such as tamping or stripping / screening.
  • Yet another aspect of the present invention relates to a coupling of two railway vehicles as described above.
  • Embodiments of the stopper lifting device 1 according to the present invention are shown in the figures 2 to 6 .
  • the lifting device 1 comprises a pneumatic cylinder 5 as well as at least one articulated arm 3, 3A, 3B mounted pivoting about an axis 13.
  • the articulated bottom 3, 3A, 3B is placed between the stopper 2, 2A, 2B and the head cross member (not shown) of the rail vehicle, which makes the stopper 2, 2A, 2B mobile.
  • a "fixed" stopper is directly secured to the cross member 10 for supporting the device 1, for example by bolting.
  • the movable stopper 2, 2A, 2B is not bolted to the cross member, but to the articulated arm 3, 3A, 3B.
  • the articulated arm 3, 3A, 3B (and the movable stopper 2, 2A, 2B) is itself advantageously fixed to a connecting piece 11 which can be removably connected to the cross-member 10. Thanks to the articulated arm 3, 3A , 3B and the pneumatic cylinder 5, the movable stopper 2, 2A, 2B can be raised in due time, in order to allow the operator to pass through the "Berne square" without obstructing the passage.
  • the pneumatic cylinder 5 is supplied by the pneumatic circuit of the vehicle, in particular by the main line 8 (commonly called "CP") of the vehicle.
  • the lifting device is compatible with a large number of vehicles.
  • the connecting piece 11 therefore connects the articulated arm 3, 3A, 3B to the cross member 10.
  • This connection which must be removable, can be carried out in different ways.
  • the connecting piece 11 has a circular base whose periphery coincides with a receptacle 12 located in the cross-member 10, and can slide in the receptacle 12.
  • the connecting piece 11 is raised with the articulated arm 3, 3A, 3B and the movable stopper 2, 2A, 2B when the pneumatic cylinder 5 retracts.
  • the lifting device 1 may comprise an articulated arm 3 which is connected to one of the stops 2 of the vehicle, the other stop being fixed and bolted to the cross-member 10, as illustrated by the figure 6 .
  • the device 1 comprises two articulated arms 3A, 3B, connected respectively to each of two stops 2A, 2B of the vehicle, as illustrated by the figures 2 to 5 . In this way, the operator can raise one or the other of the mobile buffers 2A, 2B of the rail vehicle, depending on the side where it is located.
  • the device 1 also includes (de) locking devices 15, for example comprising ratchets or ratchet wheels.
  • a first lock prevents the untimely movement of the stopper up, for example when the vehicle is in motion, and a second lock makes it possible to prevent any accidental descent of the stopper when it is in the high position during the coupling operation.
  • the articulated arm 3 is connected to the jack 5 which is located in the example cited located under the buffers 2.
  • the jack 5 is located above the movable buffers 2A, 2B.
  • the cylinder operates in a pressure range between 8.5 and 10 bars. Its length is determined in such a way that at its maximum stroke, the stopper is positioned more than 2000 mm from the TOR (top of rails), or according to the regulatory space.
  • the jack will therefore make it possible to raise a stopper with a weight of 170 to 220 kg in a rotational movement on an articulated arm at an angle sufficient for the low point of the stopper to be at least 2000 mm from the TOR.
  • the present invention makes it possible to avoid many accidents thanks to a simple and inexpensive device, which can be adapted to any type of railway vehicle. Access to the "Berne square" is facilitated and productivity during the hooking / unhooking of locomotives and wagons is increased.
