Definitions

  • the present invention relates to a lifting device which can be fitted in railway and tramway vehicles, particularly for enabling disabled people to board and alight.
  • a lifting device with a vertical guide upright along which a horizontal platform is movable vertically between a lowered position substantially level with the railway platform or pavement and a raised position substantially level with a floor of the vehicle has already been proposed.
  • the object of the present invention is to provide a simple and compact lifting device which does not require appreciable modification of the access opening of the vehicle.
  • this object is achieved by a lifting device having the characteristics which form the subject of the claims.
  • a railway vehicle schematically indicated 1 is beside a railway platform 2.
  • the vehicle 1 has a floor 4 which is above the platform 2 by a distance H.
  • a lifting device according to the invention, generally indicated 6, comprises a platform 8 and an operating device 10 which can move the platform 8 parallel to its starting position between a lowered position substantially level with the railway platform 2 and a raised position substantially level with the floor 4.
  • the operating device 10 comprises a structure 12 which, in the embodiment shown in the drawings, takes the form of a right-angled arm.
  • a first end of the arm 12 is articulated to the body of the vehicle 1 about a horizontal axis 14 and its second end carries a pulley 16 which can rotate freely relative to the arm 12 about a second axis 18 parallel to the first axis 14.
  • the platform 8 is connected to the pulley 16 so as to be fixed rigidly thereto for movements about the axis 18. This connection is effected by means of a plate 20 fixed to the pulley 16 and carrying a shaft 22 on which the platform 8 is articulated about an axis 24.
  • the plate 20 has one or more abutments (not visible in the drawings) which prevent the platform 8 from pivoting under the effect of its own weight in the sense indicated by the arrow 26 in Figure 1.
  • the platform 8 is free, however, to pivot about the axis 24 in the opposite sense, indicated by the arrow 28 in Figure 1.
  • a pulley 30 On the first end of the arm 12 there is a pulley 30 which is rotatable about the axis 14 independently of the arm 12.
  • a radial flange 32 is fixed to the pulley 30 and the end of a fluid actuator 34 is articulated thereto, the body 36 of the actuator being articulated to a support (not shown) which is fixed relative to the vehicle 1.
  • a first end of a flexible and inextensible transmission element 38 constituted, for example, by a metal cable or a chain, is anchored on the pulley 30.
  • the second end of the flexible element 38 is anchored on the pulley 16.
  • the ends of the flexible element 38 are wound partially onto the pulleys 16 and 30 and a central portion of the flexible element 38 cooperates with a transmission pulley 40 rotatable on the arm 12 about an axis 42.
  • a pressurized-fluid actuator, indicated 44, is intended to pivot the arm 12 about the axis 14.
  • the arm 12 and the actuator 44 are connected by means of a wheel 46 which is fixed rigidly to the arm 12 and on which a cable or chain 48, connected to the end of the rod of the actuator 44, is anchored.
  • the operating device 10 described above has the characteristic that it enables the platform 8 to move between the lowered position and the raised position in a direction such that it is constantly parallel to its starting position and this is achieved solely by means of the pivoting of the arm 12 about the axis 14. This is possible since the device described reproduces the kinematic behaviour of an articulated quadrilateral.
  • the arm 12 and its pulleys 16 and 30 and the flexible transmission member 38 are equivalent to an articulated quadrilateral 50 having a horizontal side 52 which is fixed relative to the vehicle, a side 54 which is fixed to the platform 8, and two further sides 56 and 58 which interconnect the corresponding ends of the sides 52, 54.
  • the side 58 of the articulated quadrilateral 50 would correspond to a line joining the pivot axes 14, 18 of the operating device 10.
  • the concept upon which the present invention is based consists of the provision of transmission means which can impart to the platform 8 an angular movement relative to the arm 12 about the axis 18 the movement being equal in extent but in the opposite sense to the angular movement of the arm 12 relative to the axis 14.
  • the side 58 is inclined at an angle ⁇ to a vertical axis, in the condition in which the platform 8 is level with the railway platform.
  • the angle between the platform 8 and the side 58 is 90°+ ⁇ .
  • the side 58 is made to perform an angular movement of amplitude ⁇ 1 about the axis 14 until the platform 8 is brought level with the floor of the vehicle.
  • the side 58 is inclined at an angle of ⁇ + ⁇ 1 to the vertical reference axis whilst the platform 8 is inclined at an angle of 90°+ ⁇ + ⁇ l to the side 58.
  • the platform 8 performs an angular movement relative to the arm of equal extent but in the opposite sense to the angular movement of the arm relative to the vehicle.
  • the actuator 34 connected to the pulley 30 is in the rest position and the flange 32 fixed to the pulley 30 cooperates with a stop 60 carried by a support which is fixed to the vehicle and can prevent the pulley 30 from rotating in the sense indicated by the arrow 62 in Figure 2.
  • the platform 8 is substantially level with the railway platform 2 and can receive a wheelchair 64.
  • the actuator 44 is operated so as to bring about a pivoting of the arm 12 in the sense 66.
  • the pivoting movement of the arm 12 ends when the actuator 44 reaches the end of its travel and, in this situation, the platform 8 is level with the floor 4 ( Figure 3).
  • the arm 12 In order to retract the lifting device into the vehicle, starting from the configuration of Figure 3, the arm 12 is kept in the raised position and the actuator 34 is operated, rotating the pulley 30 in the sense 68.
  • the flexible element 38 is tensioned and brings about rotation of the pulley 16 and pivoting of the platform 8 fixed thereto, retracting the platform 8 into the vehicle (see Figure 4).
  • the platform 8 Upon completion of the lifting, the platform 8 extends parallel to the access opening of the vehicle and obstructs the way through the access opening. To place the device in the rest condition, it suffices to rotate the platform 8 through 90° about the axis 24 as indicated by the arrow 70 in Figure 4 so as to orient the platform 8 perpendicular to the access opening of the vehicle.
  • the device according to the invention also enables the platform 8 to be oriented in a chute configuration, as indicated in Figure 5, to allow disabled people to be evacuated from the vehicle 1 in the event of an emergency.
  • this can be achieved simply by pivoting the platform 8 so that it is parallel to the loading opening and then allowing the pulley 30 to rotate freely.
  • the platform 8 is brought to the inclined position of Figure 5 under the effect of its own weight.
  • the pulley 30 can be released in various ways and one of these consists of the removal of the stop 60 and the de-activation of the actuator 34.
  • the pulley 30 is thus no longer restrained in any way and is free to rotate under the effect of the weight of the platform 8.
