Definitions

  • the present invention relates to a device for aiding the handling, dismantling and transport of a coupling head, in particular a coupling head of a railway vehicle. It describes in particular a specific support suitable for disassembling and reassembling a coupling head, as well as its storage and transport.
  • the present invention also covers a method of handling a coupling head, in particular during maintenance operations.
  • railway vehicles such as trains or trams often comprise several wagons assembled by coupling elements, which have to be regularly dismantled for inspection or maintenance operations.
  • the coupling of a wagon is generally fixed to the chassis of the wagon set back with respect to the skirt or the external fairing of the vehicle. Access to the hitch attachment points is thus limited.
  • the insertion of a support device making it possible to manipulate the hitch is then often difficult due to the lack of space.
  • the hitch comprises many fragile elements such as pneumatic, electric or hydraulic lines, damping parts and other members around the body of the hitch or passing through the body of the hitch. These various components must not be damaged when handling the coupling.
  • a solution often envisaged is the use of a support comprising a coupling head which can be connected to the coupling being overhauled.
  • the support is thus arranged in the continuity of the hitch and allows it to be handled using a suitable device such as a pallet truck.
  • this solution is not optimal either.
  • the support connected to the hitch significantly increases the size of the assembly.
  • such a support does not allow the storage of the hitch, which must be transferred to a suitable support.
  • An object of the present invention is to provide a device for assisting the handling of a rail vehicle coupling, which allows it to be dismantled, stored and transported at the same time.
  • Another object of the invention is to propose a single device allowing the handling of a rail vehicle coupling, thus making it possible to limit the number and the size of the equipment in the workshop and the number of manipulations.
  • Another object of the present invention is to provide a method of handling a rail vehicle coupling that is simpler and more efficient than current methods.
  • the aim here is to propose a method which minimizes or reduces the number of operations, the time for overhauling the hitch, and/or the number of devices required for handling.
  • the device comprises a base associated with at least two laying elements.
  • the laying elements are adapted to support the hitch at predetermined support points.
  • the width of the base preferably does not exceed the width of the hitch by more than approximately 15%, or even 10%.
  • the width of the base does not exceed the width of the hitch.
  • the width of this device is of the order of 50 cm or 70 cm or 90 cm or about one meter.
  • the width of this device is not greater than 1 meter, or even 90 cm, so as to limit its size and to be able to be easily inserted under a railway vehicle, in particular between its wheels if necessary.
  • At least one of the laying elements can form an angle of more than 90°, or between 95° and 140°, with the base, so as to be offset with respect to the base.
  • the angle can be adjustable.
  • One or both laying elements can comprise one or more holding wedges, which can be fixed or adjustable in position and/or in orientation.
  • One of the laying elements may comprise an arrow comprising at its end a laying surface, which may be of a shape complementary to the hitch.
  • the arrow preferably designates a single axis so as to limit its size over the width of the support and allowing easy insertion between the fairing elements surrounding the coupling.
  • the boom is angled so that it projects beyond the base's footprint.
  • the device does not include any element directly above the arrow, for example in the extension of the base.
  • the distance between the laying elements can be greater than the length of the base of the device to limit its size.
  • the base may be adapted to cooperate with a lifting tool or may include an integrated lifting device.
  • the device according to the present description may further comprise one or more securing elements suitable for securing a hitch and/or securing the device in a means of transport.
  • the present method facilitates or allows the handling of a coupling of a railway vehicle, in particular when it is concealed, at least partially, by its fairing.
  • concealed is understood here as adjoining or being close to and signifies a clutter in the environment of the coupling.
  • the method comprises the steps of arranging the device under the coupling, raising the device so as to make the position of the positioning elements coincide with the corresponding support positions of the coupling, separating the coupling from the railway vehicle, resting or transferring the device and the hitch, and preferably excludes any prior step of dismantling the fairing, or requires a limited number of uncluttering operations of the hitch.
  • the method according to the present description may also comprise one or more adjustment steps for one or both laying elements and/or for one or more of the wedges.
  • a railway vehicle designates any vehicle moving on a railway track, articulated and comprising several cars combined together using a coupling.
  • Railway vehicles refer in particular to trains, trams and metros.
  • the fairing designates any element of bodywork or protection of the railway vehicle, in particular those arranged at the ends of the cars near the coupling.
  • the fairing includes the elements often designated by the term skirt, deflector or any equivalent.
  • a railway vehicle excludes any other non-articulated, and/or flying, and/or floating vehicle.
  • THE figures 1a and 1b diagram the front of a railway vehicle 20 comprising a coupling 21.
  • the coupling 21 is arranged at one end of the vehicle 20 in a central position between two buffers 23.
  • the coupling head 220 ( Figure 2 ) protrudes from the fairing 22 of the vehicle 20.
  • the part of the coupling 21 fixed to the vehicle 20 is included in the fairing 22 of the vehicle 20.
  • the figure 2 shows in more detail the coupling head 220, allowing the connection of the coupling with the coupling head of another railway vehicle, and the end 210 of the coupling 21 allowing its attachment to the chassis of the railway vehicle 20.
  • the hitch 21 During inspection or maintenance operations, the hitch 21 must generally be removed from the vehicle 20 and then sent to a specialized overhaul workshop. To this end, the end 210 fixed to the vehicle 20, generally by bolts, must be detached from the vehicle 20. At the same time, the coupling 21 must be supported by an external device such as a pallet truck, a goat, a jack or any other lifting or support tool making it possible to hold the hitch 21 during its dismantling.
  • an external device such as a pallet truck, a goat, a jack or any other lifting or support tool making it possible to hold the hitch 21 during its dismantling.
  • the device comprises in particular a support 30 which can be manipulated by a lifting tool.
  • the support 30 is provided with a coupling head compatible with the coupling head to be removed.
  • the coupling 21 to be dismantled can thus be maintained by means of the offset support 30 during its dismantling.
  • Such a support 30 requires an appropriate lifting tool, capable of compensating for the balance due to the length of the hitch 21 once dismantled. Also, hitch 21 dismantled must be transferred to another medium for storage or transport to an overhaul workshop.
  • the device 1 consists of a support adapted to support a coupling 21 of a railway vehicle 20. It also consists of a support adapted to be placed under the coupling 21 to support it during its disassembly and its assembly.
  • the device 1 also serves as a transport or storage support for the hitch 21, once dismantled. It can thus be qualified as an assistance device for the handling of a hitch 21 or a transport device or a storage device.
  • the support 1 comprises a base 10 in the lower part, serving as a base. In its storage or transport position, the base 10 rests on the ground.
  • the base 10 can comprise for example two or more than two longitudinal and parallel tubular structures 11a, 11b. These tubular structures can each be provided with a recess 12a, 12b, and open at at least one of their ends. They are thus suitable for inserting a fork or pallet truck teeth or any other lifting tool, motorized or manual.
  • the tubular structures 11a, 11b can be perforated on their lower part, so as to allow the wheels of a pallet truck for example to pass.
  • the base 10 can consist of a homogeneous platform rather than a set of tubular structures, or of any other arrangement suitable for the insertion of a lifting tool.
  • the support 1 comprises a first positioning element 17 fixed to the base 10.
  • This first positioning element 17 makes it possible to support the coupling in one of its recommended or recommended positions and to maintain it in a raised position relative to the base. 10.
  • the positions advised or recommended correspond to the support points recommended to guarantee the holding and transport of the hitch 21 in the best conditions.
  • THE first laying element 17 is preferably arranged at one of the ends of the support 1, or close to one of its ends.
  • the first laying element can for example comprise a bridge or an arch or any other raised element arranged transversely to the base 10. It can be fixed to the base 10 by any suitable means such as welding, bolting and equivalent means.
  • the first laying element 17 can be arranged on the base 10 in an adjustable manner, so as to be able to assume several different positions on the base 10.
  • the first support 17 is fixedly mounted, either non-removably on the base 10. Alternatively, it can be removably mounted so that it can be replaced by another positioning element, shape and/or of different dimensions.
  • the first laying element 17 comprises on its upper part at least one spacer 17a, 17b, 17c making it possible to maintain the hitch 21 in the correct position once placed on this first laying element 17.
  • the spacer(s) 17a 17b, 17c are preferably arranged so as to correspond to the dimensions of the hitch 21.
  • a set of two side wedges 17a, 17b can be provided to grip the hitch and prevent any lateral or transverse sliding relative to the support 1.
  • a spacer 17c can be arranged on the central part of the first laying element 17 so as to stabilize the end of the hitch and thus prevent any longitudinal sliding of the hitch relative to the support 1.
  • the height of the wedges is adapted accordingly, as well as their width.
  • the central wedge 17c can be angled to stabilize the coupling head, comprising a beveled section. Other arrangements are possible depending on the needs.
  • the spacer(s) 17a, 17b, 17c can be fixedly arranged on the first laying element 17, that is to say in a non-removable and non-adjustable manner.
  • one or more of the wedges 17a, 17b, 17c are arranged in a removable and/or adjustable manner on the first laying element 17. They can for example be bolted thereto through oblong holes making it possible to modify their spacing or their orientation. In this case, the spacing d1 between two side wedges 17a, 17b can be modified according to the width of the hitch 21. Other adjustment means can be envisaged as required.
  • One or more of the wedges can also be replaced by other wedges of different size and/or shapes.
  • the first laying element 17 can be adjustable in height relative to the base 10.
  • the bolting of the transverse part can be provided on the side pillars at different predetermined heights.
  • a continuous height adjustment system such as one or more hydraulic jacks, or endless screw, or any other equivalent system can be envisaged.
  • the first laying element 17 is not adjustable in height relative to the base 10.
  • the support 1 is normally adapted to cooperate with a lifting tool, so that its height from the ground can be adapted. It can thus be raised so that the first laying element comes into contact with the hitch 21 and holds it.
  • the support according to the present description further comprises a second laying element 18 disposed at the opposite end of the base 10 or close to this end.
  • the second laying element 18 can be identical to the first laying element 17. It can for example comprise one or more wedges 17a, 17b, 17c adaptable to the geometry of the hitch 21, it can be adjustable in height or not. Its position on the base 10 can also be adjustable or non-adjustable. In this way, the support 1 can have a symmetrical appearance, where the first 17 and second 18 laying elements facing each other are identical.
  • the second laying element 18 is structurally different from the first laying element 17. It notably comprises a single arrow 18a, arranged in the middle of the width of the support 1.
  • the size of the second laying element laying element 18 is significantly less than that of the first laying element 17.
  • the width of the second laying element 18, due to its single arrow 18a, does not exceed 50% of the width d2 of the base 10.
  • the width of the second laying element 18 is preferably not greater than 30% or 10% or less of the width d2 of the base 10.
  • the second laying element 18 can be easily slid under the coupling 21 at the level of its end 210 fixed to the railway vehicle 20.
  • the second laying element 18 comprises a laying surface 18b at its end, adapted to support the coupling 21 in another of its advised or recommended positions and to maintain it in a raised position with respect to the base 10.
  • the laying surface 18b can have a complementary shape to the hitch 21 in this holding position.
  • the laying surface 18b coincides with the body of the coupling 21, generally cylindrical.
  • the laying surface 18b under these conditions preferably has the shape of an arc of a circle making it possible to marry the cylindrical surface of the body of the hitch 21. It is understood that the laying surface 18b can take any other suitable form and deemed conducive to maintaining the hitch 21.
  • the arrow 18a of the second laying element 18 is preferably fixed in an adjustable manner on the base, so as to be able to assume several positions along the length of the support 1.
  • the spacing L1 between the first 17 and second 18 elements laying can be adapted to the dimensions of the coupling 21.
  • the distance L1 is determined at the level of the laying surfaces of the first 17 and second 18 laying elements.
  • the arrow 18a is slidably fixed in a tubular structure 13 of the base 10.
  • a clamping system by means of one or more clamping screws can block the arrow 18a in a given position.
  • Other equivalent arrangements can be envisaged such as a rail in a slide, fixed by means of flanges, or a series of holes allowing the boom 18 to be bolted at different predetermined positions.
  • the boom 18 may be provided with means for adjusting its height (not shown). As for the first laying element 17, the height adjustment may not be useful. In this case, the first 17 and second 18 laying elements are arranged by default so as to maintain the coupling in a horizontal position.
  • orientations of the first 17 and second 18 laying elements with respect to the base 10 of the support 1 can be determined independently of one another.

  • the reduced width d2 also allows easy handling of the support 1, in particular under the railway vehicle 20 or between its various fairing elements.
  • the dimensions of the base such as its width d2 and its length L2 define the maximum size of this device at its base 10.
  • tie-down hooks such as tie-down hooks, straps or retaining collars can be arranged on the support 1 or combined with the support 1.
  • the tie-down hooks, or any equivalent device can be used to secure the coupling 21 on the support 1 and/or to secure the support in a transport vehicle.
  • Protective elements can also be arranged on the laying surface 18b and/or on the first laying element 17, to protect the hitch from any damage.
  • a layer of polymer or any other damping material may for example be provided for this purpose.
  • the length L2 of the base 10 is also optimal, both to facilitate the insertion of the support 1 under the hitch 21 and to limit its size.
  • the length of the base is less than that of the coupling 21.
  • the length of the base is for example between 1 meter and 2 meters, preferably of the order of 110 to 160 cm. Preferably, it is also less than the distance L1 which separates the first 17 and second 18 laying elements, or the corresponding laying surfaces.
  • the present invention also covers a method of handling a rail vehicle coupling 20.
  • the method comprises a step of placing under the coupling 21 a support 1 as described above.
  • the support 1 is arranged so that the first 17 and the second 18 laying elements coincide with the pre-established support positions of the coupling 21.
  • the support 1 is arranged so that the second laying element 18, offset from the base 10 is placed under the end 210 of the coupler 21 fixed to the railway vehicle 20.
  • the method includes a step of raising the support 1 until the first 17 and second 18 laying elements are brought into contact with the hitch 21.
  • the present method does not include any prior step of dismantling the fairing or a fairing part of the vehicle 20.
  • the support 1 can be raised by any suitable lifting tool, including by an integrated lifting device.
  • the method includes a step of uncoupling the hitch 21 from its vehicle 20.
  • the uncoupling may consist of unbolting it.
  • the coupling resting on the support 1, it can be easily moved away from the vehicle 20 by moving the support 1.
  • the lifting tool used comprises the appropriate means of movement.
  • the support 1 can then be placed on the ground for storage, or on a transport platform for its transfer to an overhaul workshop. It is understood that once the hitch 21 is placed on the support 1, it is not no need to transfer it to another type of support to move or store it.
  • the method may include a revision or control step carried out on site or remotely.
  • the revision of the hitch 21 is advantageously carried out directly on the support 1.
  • the method includes a step of reassembling the coupler 21 still placed on the support 1.
  • the support 1 is brought closer to the railway vehicle so as to arrange the coupler suitably for its assembly.
  • the support 1 is then raised, or by means of any suitable lifting tool, which may include, where appropriate, integrated lifting means.
  • the hitch can be secured again to the rail vehicle 20.
  • the hitch 21 is remounted on the vehicle 20, the support 21 is released.
  • the method according to the present invention may include a prior step of adjusting one or more of the different elements such as the first laying element 17, the second laying element 18, the arrangement of one or more of the wedges 17a, 17b, 17c or any other adjustable element.
  • the method may further comprise a step of strapping or securing the hitch 21 on the support, or securing the support 1 in a means of transport.
