Definitions

• the present invention relates to a wagon for handling heavy loads such as rails.
• the invention also relates to the use of such a car on a railroad provided with a catenary.
• flat cars are generally used, that is wagons whose floor, placed on a chassis, forms a simple platform without a box or a roof.
• this type of wagon is often equipped with one or more motorized lifting devices, which allow the rails to be moved outside the platform.
• the object of the present invention is to propose to a handling car, which can be used with such ease in the presence of a catenary supplied with electricity along a railroad track, that in combination with an installation to load this wagon, in particular in a maintenance station.
• the subject of the invention is a wagon for handling heavy loads such as rails, comprising, on the one hand, an elongate platform for transporting loads on a railway track, this platform being provided with at least one load loading and unloading device, and, secondly, a roof covering of the platform, which is situated above the loading or unloading device or devices, and a roof comprising, at the at least one fixed roof element, which is rigidly connected to the platform and which covers a first longitudinal part of the platform, and at least one movable roof element which is displaceable relative to the fixed roof between an extended position, in which the movable roof element extends, at least substantially, projecting from the fixed roof element in the longitudinal direction of the platform and thus covers a second part longitudinal of the platform, adjacent to the first part of the platform, and a retracted position, in which the movable roof element and the fixed roof element are, at least for the most part, superimposed vertically so that the second part of the platform is discovered up.
• the idea behind the invention is to circumvent the disadvantage associated with the permanent presence of a continuous roof covering the platform of the car, proposing a modular roof, at least one of the roof elements is movable relative to a fixed roof element, as defined above.
• the movable roof element (s) When the movable roof element (s) are in their retracted position, one or more longitudinal parts of the platform are vertically accessible from the top, which then makes it possible to use an aerial installation to load the platform, typically when the wagon is at a maintenance station: for example, a traveling crane, that is to say a structure which moves on two parallel parallel airways and which comprise beams allowing the displacement of a lifting apparatus of heavy loads to be handled, can then be used to place on the platform a lot of rails, this batch of rails being introduced between the platform and the roof laterally to the wagon while the lifting chains rails, actuated by the traveling crane, extend vertically through the roof area (s) cleared by the movable roof element (s) in the retracted position.
• the movable roof element (s) When the movable roof element (s) are in their deployed position, they extend the fixed roof element (s). in the longitudinal direction of the platform and thus form, together with this or these fixed roof elements, a continuous roof covering the platform in length, in particular its or its loading and unloading devices, which makes it possible to satisfy the safety standards mentioned above for the catenaries to remain energized during load handling.
• the latter advantageously comprises motorized means for driving the or each movable roof element between its deployed and retracted positions.
• these motorized means include a manual disengagement system, which allows uncoupling the motorized means vis-à-vis the movable roof element and thus move manually this roof element to one of its two extreme positions, for example in case of malfunction of the motorized means or blocking of the movable roof element during its movement.
• the latter advantageously further comprises control means adapted to disable the loading or unloading device or devices when the or at least one of the movable roof elements is not in his deployed position. Under these conditions, the user is forced to deploy all movable roof elements before being able to operate the loading or unloading device or devices, limiting in particular the risk of accident in the presence of a catenary.

• This safety aspect of the car 1 will be described in more detail below, in the context of the description of an example of use of the wagon with reference to FIGS. 1 and 7 to 9, being noted that, for the sake of clarity , many details of realization of the car 1 are not included or are shown only very schematically in Figures 7 to 9. Initially, it is considered that the car 1 is in the configuration shown in Figure 1.
• the four movable panels 74i, 74 2 , 76i and 76 2 are then in respective positions retracted vis-à-vis their corresponding fixed panel 72i, 72 2 : the front panels 74i and 74 2 are then in a state translated at most rearward while the rear panels 76i and 76 2 are in a state translated to the maximum forward. Under these conditions, the panels 74i and 76i are, almost entirely, arranged below the fixed panel 72i, each by superposition along the vertical.

Similar chains or lifting means can thus be introduced through these three perforated zones Z, in particular in order to load on the platform 10 the rails 2, not shown in FIGS.
• the car 1 leaves the above-mentioned maintenance station, rolling on the rails R, until reaching an intervention site along the railroad tracks R.
• the rails 2 stored on the platform 10 are for example to be unloaded and, to do this, the user will use the devices 30.
• the setting in motion of these devices 30 is, for reasons of safety, in particular related to the standard NF F 58-002 or the draft standard prEN 14033-1, incompatible with the presence of a catenary C supplied with electricity, running in altitude above the rails R, as shown schematically Figures 7 and 8.
• the modularity of the roof 60 is then of interest.
• the user first controls the deployment of the panel 74i relative to the fixed panel 72 ! , that is to say that, via the control cabinet 92, it actuates the motor 86 so as to translate the carriage 82 and thus the panel 74i forward, as indicated by the arrow Fi in Figure 7, until the panel reaches its deployed position shown in Figure 7, wherein the panel covers the platform portion 10C.

• a current limiter to prevent that, when the panel 76i reaches its deployed position, it is not sneaks into the panel 74 2 already deployed and that these two panels do not get together with each other.
• another order of deployment of the four movable panels than that described just above is possible, since, ultimately, the four panels are deployed, with the rear edge of the panel 76i and the front edge of the panel 74 2 joined to each other or overlapping slightly, but not wedged one vis-a-vis the other.
• the control cabinet 92 which receives corresponding signals from the end-of-travel detectors 90 respectively associated with these four panels.
• the control cabinet 92 since the control cabinet 92 has also received from the detectors 90 representative signals that each of the movable panels is in its retracted position, this cabinet 92 controls, as soon as one of the four panels mobile leaves its retracted position for its deployed position and as the movable panels are not all four in their deployed position, the actuation of light warning means and / or sound to the attention of the user, such as a beacon 94 and a siren 96 ( Figure 1).
• the wagon 1 is then in a configuration allowing the user to safely use the loading and unloading devices 30, despite the presence of the catenary under voltage C since the roof 60 then covers continuously the entire platform 10 , being interposed between the moving components of these devices 30 and the rails 2 which will be discharged using these devices from the platform 10.
• the aforementioned safety standards are thus met, so that the cabinet 92 suspends the deactivation of the devices 30 which it has maintained until now, that is to say that these devices can then be used, in particular being controlled by means of their console 50.
• FIG. 9 also illustrates the use of one of the devices 30: the arm 40 of this device no longer extends in length along the longitudinal direction of the platform 10, as in the previous figures, but extends perpendicularly to this longitudinal direction, so that the carriage 42 may, depending on its position along the arm 40, be arranged either vertically above the upper face 18A of the platform body 18, or at the outside the vertical projection of this face 18A.
• the rails 2 stored on the platform 10 can then be lifted by the hoist 46, then be moved by translation of the carriage 42 to the outside of the platform 10, laterally to the latter.
