Definitions

  • the present invention relates to a mobile gantry for vertical road signs, in particular for roads with several tracks, comprising two uprights and a horizontal transverse beam.
  • the present invention aims to provide a mobile gantry allowing temporary road signage with minimal traffic stopping time for its establishment.
  • the gantry object of the invention is characterized in that the uprights are provided with lifting devices for raising or lowering the horizontal transverse beam, in that the uprights consist of masts which, when the horizontal transverse beam is lowered, can be folded towards each other, and in that the horizontal transverse beam is made of portions which engage telescopically.
  • The: portions of this beam can engage one inside the other or one on the other.
  • the horizontal transverse beam is connected in an articulated manner to the uprights, the articulations being provided by counter events.
  • the lifting device is preferably provided with a parachute brake which operates automatically when the cable breaks.
  • the lower ends of the uprights are provided with wheel-carrying cross members and adjustable crutches.
  • the mobile gantry represented in fig. 1 comprises two uprights 11, 12 and a horizontal transverse beam 13 extending between the two uprights.
  • the upright 11 constitutes a double mast 14 made of two profiled tubes 15, 16, of the same length and of rectangular section.
  • the tubes 15, 16 are connected to a crosspiece 17, preferably by welding.
  • the cross member 17 is provided, at its free ends, with non-steerable wheels 18.
  • it has adjustable crutches 19 which make it possible to lift the wheels 18 to level everything and prevent the gantry from rolling.
  • the double mast 14 is provided with a lifting device comprising a carriage 21, a winch 22 with cable 23 and idler rollers 24 mounted on the head of the mast.
  • the carriage 21 is shown in detail in FIG. 2. It is made of two sections of rectangular tubes 25, 26 which are dimensioned so that they can slide on the tubes 15, 16. Each section comprises two side walls 27, 28, a front wall 29 and a back wall 31 The two side walls 27, 28 have a distance between them such that a very small space remains, for example 5 mm, with the tube 15. The front wall 29 and the back wall 31 are more spaced apart, for a reason which will come out later.
  • the tube sections 25, 26 are parallel and arranged at a distance which corresponds to that of the two profiled tubes 15, 16 of the mast 14.
  • the tube sections 25, 26 are connected, by their upper ends and in pairs, to the side walls 27, 28, for example by welding, by lugs 32 which project beyond the front wall.
  • the legs 32 are pierced with holes 33 made so that they are aligned.
  • the lower ends of the sections of tubes 25, 26 carry tabs 34, arranged in pairs, which are welded in an identical manner to those of the upper ends and whose holes 35 are aligned.
  • Pairs of rollers 36 are arranged inside each section of tube, near its upper and lower ends, rollers which are parallel to the front walls 29 and dorsal 31 and arranged a short distance from the latter.
  • the rollers 36 are made of sockets 37 rotatably mounted on studs 38 which extend at right angles between the side walls 27, 28. The distance between the rollers of each pair is equal to the overall distance of the double mast 14. Said rollers are used to reduce the friction between the carriage 21 and the mast 14.
  • the cable 23 is fixed, at one of its ends, to the carriage 21, passes over the return pulleys 24 and is wound up on the winch 22. By winding or unwinding the cable 23, the carriage 21 is raised or lowered on the mast.
  • the upright 12 is simple and comprises only one mast 39 rigidly fixed to a cross member 41.
  • the cross member 41 of the upright 12 comprises, as for the upright 11, wheels 42 and adjustable crutches 43.
  • the upright 12 is provided with 'a lifting device consisting of a carriage 44, a winch 45 with cable 46 and idler rollers 47.
  • the only difference between the carriage 44 and the carriage 21 is that it only comprises a section of tube instead of two. Otherwise, its construction is identical to that of the carriage 21.
  • the wheels 42 are, unlike the wheels 18, mounted in yokes and can be oriented around vertical shafts.
  • the horizontal transverse beam 13 which connects the two uprights 11, 12 is made of several tubes.
  • the tubes can have sections of all kinds, for example rectangular or round sections.
  • the middle portion 48 is constituted by two identical tubes of rectangular section arranged parallel and interconnected, preferably by flanges allowing the extension of the two elements but also by welding. These two tubes can be closed at one of their ends and the openings of the other ends are opposite.
  • tensioning cables 59 can be used, one of which is in the form of a chain.
  • the two lateral portions 49, 51 of the horizontal transverse beam 13 are made of tubes of rectangular section, the external profile of which is adapted to the internal profile of the central portion 48, so that the lateral portions 49, 51 can be introduced and slide in the middle portion 48. Thanks to this arrangement, the length of the horizontal transverse beam 13 can be reduced by more than a third of its total length.
  • Adjusting screws 52 are arranged near the open ends of the tubes of the middle portion 48, screws which are guided perpendicularly in threads of the tubes of the middle portion 48 and by which it is possible to block the side portions 49, 51 and prevent any play between the middle portion and the side portions.
  • the middle portion 48 has, in addition, holes 53 which pass through the two tubes, holes which, in determined positions of the side portions 49, 51, are aligned with holes (not visible) provided in the ends of the middle portion, so that certain positions can be chosen in advance and ensured by pins 54.
  • the lateral portions have, at their other ends, also holes (not visible), in which pins or tenons 55 are threaded to assemble them to the legs 34 of the carriages 21, 44.
  • the width of the lateral portions determines the distance between the said portions paws.
  • the tabs 32 disposed at the upper ends of the carriages are intended for fixing braces 56, braces which, at their other ends, are connected by pins passing through corresponding holes in the lateral portions.
  • the holes in the side portions are preferably reinforced with furs.
  • a second bracing is constituted by a cable 57 which extends under the horizontal transverse beam 13, between the ends of the lateral portions and which is stretched, not sant in stays, under the horizontal transverse beam.
  • the two rectangular tubes 25, 26 of the carriage 21, as well as the tube of the carriage 44, are provided with parachute brakes (not shown) which, when the cable 23 or 46 is broken, block the corresponding carriage in its position.
  • These brakes are provided with known blocking devices, devices which ensure the carriage is retained as soon as the corresponding cable breaks.
  • the various parts of the portico are in galvanized steel.
  • the width of the gantry, in the assembled state, is 14.5 m maximum and is therefore likely to be used for three-lane roads with an emergency lane.
  • the clear height above the carriageway is 4.5 m and the total height is approximately 6 m.
  • the pins 55 which connect the lateral portions 49, 51 of the horizontal transverse beam 13 to the carriages 21, 44 have a well-defined function. They serve as pivot axes for folding the gantry.
  • the braces 56 When the braces 56 are released after removing the pins, the masts can be folded down, and when the middle portion is shortened, the transport position of the gantry is obtained.
  • the different operations and positions are visible in fig. 3 which shows the rest of the gantry assembly operations.
  • the fully folded frame is shown loaded on the platform of a vehicle 59, for example a truck.
  • the double upright 11 is located at the rear of the vehicle, that is to say, on the unloading side.
  • the double upright 11 is pulled back about 1.2 m (position shown in dotted lines).
  • the carriage is blocked by means of the winch and the double upright is raised (fig. 3b).
  • the middle portion 48 of the transverse beam is supported by an easel 61.
  • the double upright 11 is pulled back so that the lateral portion 49 comes out of the portion median of a sufficient distance so that the bracing 56 can be fixed to said lateral portion (fig. 3c).
  • the lateral portion 49 is removed from the middle portion of the desired length (fig.
  • Fig. 3g shows the position adopted for moving the gantry crane on its own wheels and towing it, even over great distances. For this, only the braces 56 are removed from the lateral portions 49, 51, so that the uprights can be partially folded towards each other so that the height of the gantry does not exceed the standards set for passages under bridges .
  • Any known means may be used to lift the horizontal cross beam.
  • Said beam can, for example, be lifted by means of a motor or a manual system.
  • Motor operated systems can be actuated by electric motors or by hydraulic systems using pistons.
  • a typical manual system will use cables and a crank.
  • a third mast may be necessary to provide adequate support for the horizontal cross beam.
