- Transportable and adaptable lighting system and method of lighting a construction site on railway tracks Transportable and adaptable lighting system and method of lighting a construction site on railway tracks.
- the present invention relates to a portable and adaptable lighting system comprising on the one hand rechargeable batteries and on the other hand light tubes, each light tube being typically connected to a battery by an electric cable.
- the device according to the invention is particularly intended for the railway environment to provide adaptable lighting according to the various configurations of use envisaged, but its use is also conceivable outside this field.
- One particularly targeted application is to provide lighting for intervention areas during night ballasting operations on railways.
- This is meant particularly the work of setting up or renewal of track ballast, by means of trains work, called “ballast" with several hopper cars carrying hoppers of gravel, the gravel being poured on the tracks directly from said hoppers and therefore under the hoppers, then leveled, compacted etc. to form the ballast of the track.
- trains work called "ballast”
- ballast with several hopper cars carrying hoppers of gravel, the gravel being poured on the tracks directly from said hoppers and therefore under the hoppers, then leveled, compacted etc. to form the ballast of the track.
- ballast Several specific problems arise when carrying out such work. In the first place, they are usually done at night to minimize the inconvenience of using the lanes during the day.
- Each hopper car carries several hoppers, so several points of discharge of the ballast, and therefore several areas that it is necessary to illuminate, simultaneously or not, depending on the hoppers used.
- the train used can have many hopper cars, and therefore extend over considerable distances.
- a train ballast can have about twenty wagons and measure up to 300 m long.
- ballasting operations take place in countryside areas that do not benefit from any lighting or energy source that can be used for site lighting, especially as the ballast train moves during operation.
- the duration of each operation is relatively long, depending on the length of lane under intervention.
- a lighting system comprising a housing with a rechargeable battery that can be fixed on a metal surface, for example a car, by magnets, and a lamp connected to the housing by a flexible tube to guide the lamp in different positions relative to the case.
- This system is intended to provide emergency lighting, and the connection of the lamp to the housing by a flexible tube allows only possible use, the lamp remaining permanently mechanically linked to the housing that serves as a support.
- DE9302706U1 a portable lighting system associating a battery pack and a lamp connected to the battery pack by a cable, but the means for supporting and fixing the box on the one hand and the lamp on the other hand are not intended to allow use in various configurations both for the temporary fixing of the housing and for maintaining the lamp in position.
- a system comprising a carrying case comprising a rechargeable battery, and lamps that can be stored in the case or attached to a separate support that can also be stored in the case.
- This system has the advantage of offering a certain ease of transport, but remains bulky and does not allow to fix independently the case and the lamp or lamps on various support and various positions, as is the case in particular to ensure the lighting of the intervention zones during night ballasting operations on railways, the lighting means must be brought on site easily, positioned and fixed easily on wagons in the proper positions to ensure the best possible lighting, and be moved with the wagons without intervention of the operators to move the lighting.
- the present invention aims to provide a lighting system adapted to address these various problems.
- the lighting means must be able to be installed quickly, and also quickly removed to be moved from one place to another on a wagon, or from one wagon to another, or from one train to another , and allow in the meantime to recharge the batteries.
- the lighting shall be capable of being oriented to allow optimum illumination of the track, and therefore both the batteries and the light sources must be able to be arranged and fixed in various places of the wagons, on zones of various geometrical configuration, or on supports other than wagons and also be hand-held, both for their transport and for possible use of local manual lighting.
- the lighting power must of course be sufficient, for example 1000 lm in white 6000 ° K, and the duration of the lighting must also be sufficient, for example of the order of four hours, involving holding the batteries of duration at least four hours in operation.
- the portable lighting system must also be able to be used outside its particular application in use fixed on a ballast car, for example carried by hand, temporarily maintained on different types of supports, placed on the floor. ground, etc. so as to offer maximum flexibility of use on site.
- the subject of the invention is a transportable and adaptable lighting system comprising at least one autonomous assembly comprising a battery pack and a light tube connected to the battery pack by an electric cable, without any other mechanical connection
- the battery pack comprises on the one hand support means for the light tube and on the other hand a set of holding and fixing means comprising a handle for holding by hand magnets for attachment to metal surfaces , hook means for attachment to a wire element or elongated or on the edge of a wall, these holding and fixing means being arranged on the battery pack in a fixed manner and so as to allow a direct use of n ' any of these means without adaptation, and the light tube being provided with its own magnetic fastening means.
- the battery pack has a general rectangular parallelepiped shape having two large faces, two small faces and two medium faces, and presents:
- first hook means being arranged to be engaged on a wire-like element or strap or on the edge of a wall, on a third face, preferably a first average face, second hook means arranged to be engaged on a wire-like element or strap or on the edge of a wall,
- the handle which can also advantageously be arranged to serve as a means of supporting the light tube.
- One of the small faces will preferably be used for the electrical connections of the tube and the charger, as will be seen later, while the second small face will preferably be kept free so as to serve as a laying surface of the battery pack on the ground or on other substantially horizontal surfaces.
- the battery pack according to the invention allows numerous options of installation, maintenance and fixation, thus allowing its use in many configurations of parts or bodies that can be used to support the block. battery, carrying itself, or not, according to the needs and possibilities, the light tube which is connected to it electrically. It will also be noted that, in certain configurations, a battery pack can be used to power several light tubes.
- At least some of the hook means are formed from blades comprising a flat part attached to one side of the battery block and folded to form said hook, and the magnets are integrated. in said flat parts.
- the light tubes are LED tubes, generally known elsewhere, comprising a plurality of LEDs distributed on an elongated flat support also for the connection said LEDs.
- these tubes are preferably rotatably mounted in magnetic end supports, thus allowing the magnetic attachment of the tubes to the walls of the wagons or other suitable elements, and allowing a pivoting orientation of the tube, for directing the lighting in such a way that desired, regardless of the inclination of the support wall.
- the lighting system comprises storage cases arranged to each receive a predetermined number of light tubes and associated battery packs, the tubes being arranged substantially parallel in the same plane, and all the battery packs of a same case being then connected to be recharged simultaneously, from a single charging unit, external to said case or integrated therein.
- the number of tubes and battery packs contained in the same case preferably corresponds to the number of tubes necessary for lighting a car of the train ballast, so that a case corresponds to a wagon.
- a case may typically contain four sets of light tubes and battery packs.
- Another advantage is that it is possible to use the case containing the plurality of light tubes as a more powerful lighting means, since concentrating on a reduced surface the light power of all the light tubes contained in the storage case.
- each set light tube - battery pack also includes a radio receiver and a remotely controllable switch to remotely control the startup of the tubes and their extinction, individually or in groups.
- This particularly advantageous arrangement thus makes it possible to avoid long journeys along the train to control the lighting on each wagon or group of wagons, and thus makes it possible to easily extinguish remote light tubes not useful, thus preserving their lighting capacity by avoiding unnecessary discharge of the batteries.
- the radio receivers may be separated from the battery packs and connected to them or to the tubes by an extensible cable, for positioning the receivers in areas of better reception, independently of the situation of the tubes and battery packs.
- the radio receivers may also include fixing magnets to enable their quick and easy installation.
- the invention also relates to a lighting method of a railroad ballast yard, the ballast yard being made by means of a ballast train comprising a plurality of hopper cars containing the gravel intended to form the ballast, a method according to which a lighting system as defined above is used, is placed on each wagon a predetermined number, including four, of light tube-battery pack assemblies each provided with a radio remote control receiver, the tubes light fixtures being fixed by means of their rotating magnet supports in the lower part of the wagons, and oriented so as to illuminate the working areas situated under the hoppers and in the vicinity thereof, and by means of a radio transmitter the commissioning or stopping a predetermined group of said sets corresponding to wagons carrying hoppers implemented.
- the sets of tubes and battery pack can be divided into four groups, respectively on each side of the train and for each half-train, ie a front half and a rear half.
- Each group of tubes can be commissioned independently, easily and remotely, depending on the needs of the site, and avoiding leaving in service groups of useless light tubes.
- this provision is only an example and can be modified according to the needs and configuration of the site.
- FIG. 1 is a perspective view of a single battery pack according to the invention
- FIG. 2 is another perspective view of the battery pack, at an angle of view opposite to that of FIG. 1, and with a light tube held on the battery pack,
- FIGS. 3 and 4 are sectional views of the battery pack in a plane parallel to the large faces of the block and according to an orthogonal plane
- FIG. 5 is an illustration of an example of implantation of battery packs and light tubes on a wagon of a ballast train
- FIG. 6 is an overall diagram showing a distribution of the groups of light tubes on such a train
- FIG. 7 illustrates the possibility of using the battery pack as a support for the light tube, placed on the ground
- FIG. 8 illustrates the possibility of using the battery pack as a support for the light tube, held in the hand of an operator
- FIG. 9 illustrates the possibility of attaching the battery pack to the belt of an operator, who only holds the light tube by hand,
- FIG. 10 represents a case for storing and transporting a set of several light tubes with their associated battery packs, and showing the possibility of using such a set as a unit light source
- FIGS. 1 to 4 is a diagram illustrating the arrangement of the tubes and battery packs in the storage case and the electrical connections for recharging the batteries.
- the battery pack 1 shown in FIGS. 1 to 4 comprises a casing 10 made of mechanically impermeable and mechanically resistant plastic material and to the various attacks likely to occur in the environment of the ballast yards, typically capable of meeting the requirements for lights / flames for use during tunnel work.
- a set of batteries 3 is disposed inside the housing 10, and connected to a connector 30 fixed to a small face 16.
- the housing also comprises an electronic circuit providing protection against overloads and short circuits, temperature protection, load indicator LEDs, and a general cut-off switch.
- a light tube 2 is electrically connected to the connector 30 by an extensible cable 21.
- the light tube 2 is a cylindrical LED tube comprising, in a manner known per se, a plurality of LEDS assembled on a plate that printed circuit which also carries the electronic circuits of supply and management of LEDS.
- the tube 2 is rotatably mounted in two end supports 22 provided with magnets 23 arranged to allow the attachment of the tube on magnetic metal supports, typically sheets or steel profiles, while allowing the adjustment of the orientation of the tube. lighting by pivoting the tube in the supports.
- the housing 10 has a parallelepipedal shape comprising two large opposite faces 11, 12, two middle faces 13, 14 and two small faces 15, 16.
- a first average face 13 has a handle 41 for carrying the battery pack by hand.
- the handle is shaped so that it can also serve as a support for the light tube 2, which is then held tight between the elastic clips 42 formed on the handle.
- the shape and orientation of the handle is such that the light tube 2 is vertical when it is attached to the battery pack 1 and the latter is placed on the ground or other substantially horizontal surface, resting on its small face 15 as shown in FIG. 7.
- the block provided with the luminous tube held horizontally on the handle can easily be carried with one hand, horn shown in FIG.
- Metal blades 31 or other material, possibly elastically deformable, are fixed on the first major face 11 and magnets 32 are integrated in these plates.
- the plates 31 are folded to extend substantially parallel to the second average face 14 and thus form hooks 33, adapted for example to suspend the housing on a cable, or on the edge of a plate, sheet etc.
- the light tube can be fixed elsewhere, with its own magnet attachment means, or be held on the block handle, then located below.
- the magnets 32 are very powerful magnets, typically N50 class, allow the fixing of the battery pack on any magnetic medium, such as steel sheets or profiles, and particularly the constituent elements of a wagon of a ballast train, such as shown in Figure 5, or on metal poles of track edges.
- the arrangement of the magnets on a face perpendicular to that comprising the handle and parallel to the general direction of the handle and therefore the tube, is particularly advantageous because it allows to orient the light tube, supported by the battery pack, vertically or horizontally or in any other position, by simply orienting the battery pack according to the proper inclination.
- the battery pack also comprises other fastening means, consisting of two hooks 51, 52 extending from the edges of the second large face 12, substantially parallel thereto.
- the hooks 51, 52 preferably extend respectively from two perpendicular edges of the large face 12, and are also elastic, to allow the attachment of the battery pack for example to the belt of an operator, the operator thus keeping hands free, and able to grasp and hold the light tube alone by hand, for directed spot lighting, as shown in Figure 9.
- the multiplicity of attachment possibilities has a great advantage in the case of the lighting of a railway train, because the type of fastener used will depend on where the luminous tube must be arranged to provide the adequate lighting, which involves limitations in positioning the battery pack by staying close to the tube within reasonable range limits with respect to the length of the connecting cable 21.
- the battery pack says it can be fixed in a limited radius from the associated light tube, which implies to find him a suitable support, whatever the configuration of the environment, because the cars are not all the same it may be necessary to temporarily place it in one place and then move it, etc.
- the many possibilities of fixing solve these problems by proposing many alternatives, whether by attachment by magnet, or hung on a cable or a sheet, etc.
- Figure 5 shows a typical example of maintenance on a hopper car 91 of light tubes and battery packs, and radio receivers 6 of the remote control, which are connected to the blocks by a cable and also attached to the car by magnets.
- the diagram of Figure 8 shows a train ballast 9 with several wagons 91, for example twenty wagons, extending over a distance 1 of about 300 meters.
- the light tubes, and their associated batteries, are located on the train before the ballasting operations.
- the battery-tube assemblies are divided into four groups G1 to G4, each comprising about twenty sets, each group covering a length of 150 m.
- G1 to G4 each comprising about twenty sets, each group covering a length of 150 m.
- the remote control switch of each set the commissioning or the extinction of each of these groups independently.
- LEDS light tubes have a length of 60 cm and a power of 10 W for a clearly 1290 lm / m
- LiFe04 type batteries have a weight of 0.7 kg and a capacity of 4.2 A / H, giving a range of about 4 hours of lighting or more.
- the luminous tubes can also be declined in several colors, typically red and blue, to ensure in addition to the actual lighting, a function of signage of the works of ways.
- Figure 10 shows a case 7 for storage and transport comprising four sets of light tubes 2 and associated battery packs 1.
- the case 7 is designed to receive the tubes 2 arranged parallel in the same plane, and can thus be a unit lighting combining that of the four tubes, in other words a powerful light source for particular applications.
- the case 7 comprises the connections 71 adapted to allow the recharging of the batteries of the four blocks 1 simultaneously, and which can be automatically connected during the installation of the battery packs in the case, the charger 72 can be integrated into the case or, as in the example shown, outside the case.
- it is also provided charging stations on wheels allowing on the one hand an easier transport of said bags or briefcases and simultaneously recharge many batteries.
