Definitions

  • the invention relates to the general field of carrier masts. It relates in particular to mobile masts for quickly installing at a certain height mobile equipment to be installed more or less temporarily in given locations.
  • some mobile detection equipment intended to be deployed on different areas of terrain may require a temporary installation at a height above a given area and then a removal and transport to a new area.
  • the zone over which the equipment in question is to be located has in certain places, on the area itself or on the periphery of the latter, relief elements or constructions whose structure and height allow to position this equipment.
  • the equipment can then be positioned at the desired height by fixing, temporarily or permanently depending on the case, either on the top or on a wall, of one of these elements of relief or one of these constructions.
  • the zone considered is an open zone and one is obliged to provide an infrastructure particular for positioning the equipment considered, lighting equipment or detection equipment for example, to the height required for its proper operation.
  • the infrastructure used is then usually a mast erected vertically, at the top of which the equipment is fixed.
  • masts that can be temporarily installed at a given location and then dismantled and transported to be set up elsewhere, it is known to use telescopic masts generally mounted on supporting structures serving as a base, in or on which are installed means for stretching or retracting the mast.
  • the base is generally dimensioned such that it maintains the upright mast with its load when it is erected. It may also include complementary means, for example cylinders, to strengthen the maintenance.
  • the base of the telescopic mast is also configured so that when the mast is retracted, or partially retracted, it can be tilted from vertical to horizontal and vice versa.
  • a telescopic mast is an advantageous solution in terms of mobility. Indeed the mast can be retracted, it can usually be transported on the same vehicle as the equipment he must support, ie his load.
  • the use of a telescopic mast is thus particularly suitable, if the mass of the equipment to be positioned in height is relatively low and if the necessary height is not too important.
  • the use of a telescopic mast is more complex.
  • the mast must then be dimensioned so that its finest elements, the highest, are strong enough to support the load of the equipment and the assembly is sufficiently rigid in erected position to keep, in all circumstances , a vertical position.
  • This large dimensioning of the segments of the mast also requires the establishment of powerful means to deploy one after another the various segments and keep them in the deployed position, with the load constituted by the equipment. We then obtain an expensive device, at once complex, fragile and heavy.
  • a known alternative to the use of a telescopic mast is to use a mast formed of nested sections and provided with stays. Such a mast is generally assembled on the ground, equipped with its load, then erected vertically by means of a suitable hoist and maintained in vertical position by its stays.
  • An object of the invention is to provide an easily transportable mobile means for placing in a simple and easy manner, at a given location and for any given period of use, a relatively large mass equipment at a given height. Another object of the invention is that this mobile means also makes it easy to drop the equipment on the ground at the end of this period of use, so that it can be transported to another location or simply stored.
  • the first motor means are also configured to control the tilting of the mast from the vertical to the horizontal.
  • the mast according to the invention comprises auxiliary means for maintaining the mast in the vertical position when the first motor means are not active.
  • the mast according to the invention after their interlocking, the segments constituting the mast are held together by means of assembly flanges configured to be mounted manually without tools.
  • an assembly flange comprises a rod, configured to pass right through, in the interlocking zone two segments nested one inside the other.
  • the rod is extended at one of its ends by a fixed head, of substantially conical shape, itself extended by a gripping handle.
  • the other end of the rod has a thread on which can be screwed a conically shaped movable head substantially identical to the fixed head and extended by a gripping handle for screwing the movable head on the rod.
  • the assembly is configured such that, when the rod is inserted into openings provided for this purpose on the ends of the nested segments, the clamping of the movable head on the rod causes the partial insertion of the fixed and movable heads in the orifices of the nested segments and stiffens the assembly of the two segments.
  • the first motor means comprise a winch on which is wound a cable configured to exert traction on the base segment near its free end opposite the axis of rotation.
  • the winch is mounted on the supporting structure and configured so that the controlled winding of the cable on the winch causes the mast to pivot without damage from the horizontal position to the vertical position, keeping the cable in the wound position ensuring the maintenance of the base segment in vertical position, and that, the tilting of the mast under the action of its weight from the vertical position to the horizontal position being initiated by the second motor means, the controlled unwinding of the cable allows the tilting of the mast without damage .
  • the end of the movable portion of the sliding member that contacts the base segment of the mast is configured to conform to the shape of the segment wall, contact being provided by means of rollers. .
  • the fixed part of the sliding element comprises two rows of guide pads and the movable part comprises a sliding plate on rails along the two rows of guide pads of the fixed part.
  • the moving part of the sliding element comprises an interface piece mounted at the end of the plate and equipped with rollers configured to ensure a non-damaging contact between the plate of the movable part and the wall of the mast.
  • the device according to the invention comprises a mast 12 itself as well as first and second motor means.
  • the mast 12 itself comprises different segments which generally have the shape and structure of tubes. It is fixed on a support structure via a base 13.
  • the support structure 11 is for example constituted by the side wall of a shelter 11, as illustrated in particular by the figure 1 , the various elements being mounted on the frame of the shelter materialized by dotted lines.
  • the lower part of the mast is configured so that the mast can move in rotation about an axis 14 located at the base 13. In this way the mast 12 can occupy all the positions since a vertical position shown on the figure 1 to a horizontal position, illustrated by the figure 8 .
  • the first motor means consist of a winch 15 associated with an intermediate pulley 16 and an end pulley 17 mounted on the mast 12.
  • the assembly is arranged so that it can exert traction on the mast via a cable 18, keeping the cable wound on the winch.
  • the traction exerted on the cable 18 more generally makes it possible to drive the mast 12 in a rotational movement about the axis 14 (if the winch is rotating) or to keep the mast 12 in any inclined position (if the winch is stopped and if the free rotation of the winch drum is blocked), horizontal or vertical, for example.
  • to drive the mast 12 in rotation is actuated winch so as to wind or unwind the cable 18 as appropriate.
  • the winch 15 is stopped and the free rotation of the drum is blocked.
  • the second motor means are mainly constituted by a sliding element 19 consisting of a fixed part 191 and a movable part 192 slidable along the fixed part between a retracted position, as shown in the detail of the figure 1 , and a relaxed position as shown in the figure 9 .
  • the mobile part 192 is slidable along the fixed part 191 so that its free end can remain in contact with the mast 12 when this mast pivots from the vertical position to the horizontal position, and as long as the angle of inclination of the mast relative to the vertical remains below an angle ⁇ 0 , representing the angle beyond which, certainly, the mast unbalanced by the inclination spontaneously flips to the horizontal under the action of his own weight.
  • the holding in contact is achieved by means of actuators configured to push the moving part towards the mast and consequently to push the mast out of its vertical position if it is not retained in a vertical position, moreover, by the first motor means.
  • actuators may for example consist, as illustrated by figure 1 , in one or two jacks, arranged vis-à-vis the movable portion 192 so as to be compressed when the movable portion 192 is itself in the retracted position.
  • these actuators may for example consist of two cylinders 193 and 194 mounted on either side of the sliding element 19.
  • the sliding element 19 is arranged on the supporting structure, the shelter wall here, so that, when the mast 12 itself is erected in a vertical position using the first motor means, the cable 18 being held in tension by the winch, it presses on the free end of the movable portion 192 of the sliding element 19, so as to maintain it in fully retracted position, as shown in FIG. figure 1 .
  • the actuators are cylinders 193 and 194, they are then maintained in compression via the mast 12 under the action of the tension exerted by the winch 15 on the mast 12 through the cable 18, as shown on the detail of the figure 1 .
  • the movable part 192 of the sliding element 19 is configured to come in point contact with the mast 12, or have a free end configured to match the outer shape of the mast 12 so as to surround the latter partially and avoid occasional degradation of the mast wall in the contact area.
  • the mast 12 itself is a demountable mast having a base segment 121 fixed on the base 13 via the axis of rotation 14 and a plurality of elementary segments 122 nestable into each other, of identical sizes or different sizes depending on the intended use, the terminal segment opposite the base segment 121 being intended to carry the element 31 to be placed in height, a set of sensors for example.
  • the base segment 121 as well as the elementary segments 122, the number of which is a function of the height of the mast to be erected, are joined to each other by their ends.
  • each elementary segment 122 has a male end and a female end.
  • the end movable base segment 121, opposite the axis of rotation 14, is a male end. The dimensions of the male and female ends are defined so that the male end of one segment can be engaged in the female end of another segment.
  • these segments 121 and 122 are configured to be assembled by hand by simple interlocking.
  • the dimensional tolerances of the ends are also defined so that the interlocking is performed with a minimum clearance, however, allowing the interlocking segments by hand.
  • Their assembly thus advantageously requires no insertion tool as in the case of a tight fit for example.
  • This structure in removable segments thus advantageously allows, as illustrated by the figures 2 and 3 , to have a mast 12 having an operational configuration of the desired length, and a storage configuration in which the different segments 122 are disassembled, the length of the mast itself 12 being reduced to that of the base segment 121, which advantageously facilitates the transport of the mast.
  • the base segment 121 as well as the motor means, 15, 16, 17 on the one hand and 19 on the other hand, can thus be transported with the carrier structure 11 and the elementary segments 122 transported separately.
  • the end pulley 17 of the first motor means mounted on the base segment 121, is arranged on this segment, with respect in particular to the axis of rotation 14. such that the intensity of the force to be exerted by the winch 15 to drive the mast 12 in rotation is minimal.
  • the interlocking assembly of the different segments constituting the mast 12 itself is completed by additional means whose role is to eliminate the effects of the existing interlocking game on the rigidity of the mast 12 thus formed, a game also necessary in the extent that the segments are intended to be assembled by hand, that is to say without the use of force insertion means for example.
  • auxiliary means are constituted by assembly flanges 50 illustrated by the representations 5-a and 5-b of the figure 5 .
  • an assembly flange 50 is constituted by a rod 51, of circular or square section, passing right through, in the interlocking zone 43, two segments 41 and 42 nested in each other, as illustrated in FIG. figure 4 .
  • the rod 51 is extended at one of its ends by a fixed head 52, of substantially conical shape, itself extended by a gripping handle 53. Its other end also has a thread 56 on which can be screwed a head mobile 54 substantially identical in shape to the fixed head 52 and also extended by a grip 55 for screwing and hand tightening the movable head 54 on the rod 51.
  • each segment 121 or 122 in addition to the establishment of means for making a play-free connection between the different segments 121 and 122 of the mast 12, it is possible to further strengthen the overall rigidity by acting directly on the structure of each segment 121 or 122. For this purpose it is possible for example to reinforce the rigidity of each segment, which is basically like a tube, by implanting a light internal framework which can take various known forms not described here.
  • the motorized mast as described in the foregoing paragraphs in a particular embodiment taken as an example advantageously makes it possible to automatically pivot the mast 12 itself, equipped with its load 31, with a fixed vertical position. to a horizontal position also fixed, and vice versa.
  • FIGS. 6 to 8 illustrate how the motorized mast automatically moves from a vertical position (state I), as illustrated by the figure 1 at a horizontal position (state IV) such as that illustrated by the figure 8 .
  • the process followed begins with the start of the winch which regularly unrolls the cable 18.
  • the unwinding of the cable induces the relaxation of the stress imposed by the traction of the cable 18, via the mast 12 on the movable part 192 of the sliding element 19.
  • the relaxation of the stress results in a gradual relaxation of the actuators, the cylinders 193 and 194 as the cable 18 unfolds.
  • This detent in turn induces an action on the moving part of the sliding element 19 which moves so as to move the mast 12 away from the vertical (state II), as illustrated by FIG. figure 6 .
  • the movable portion 192 of the sliding member 19 approaches the relaxed position while increasingly spacing the mast 12 from its vertical position and thus initiating its tilting.
  • the action of the sliding element 19 on the mast 12 continues thus until it is fully relaxed (state III).
  • the mast 12 is then inclined relative to the vertical angle greater than the angle ⁇ 0 beyond which it performs a spontaneous rocking to the horizontal under the action of its own weight, as illustrated by the figure 7 .
  • the tilting speed is then regulated by the unwinding speed of the cable 18.
  • the operator can unload the mast of his load 31, then reassemble another load or proceed to a height adjustment of the mast by adding or removing an elementary segment 122. It can then proceed to the automatic repositioning of the mast in a fixed vertical position, by operating the winch 15 so as to wind the cable 18, the cable winding automatically causing tilting of the mast from horizontal to vertical.
  • the winch 15 is stopped and the free rotation of its drum is blocked, so that the tension of the cable 18 ensures the maintenance of the mast vertically and therefore the maintenance of the sliding element 19 in the retracted position (state I).
  • the operator can also, at the end of the period of use of the equipment placed at the top of the mast for example, dismantle the equipment and dismantle the mast, that is to say the disassembly of the different segments issementaires122.
  • the base segment 121 integral with the winch via the cable 18, can be returned to the vertical position in the same manner as for straightening the assembled mast (states V and VI illustrated by the figures 9 , 10 and 2 ).
  • the starting stop and the blocking of the free rotation of the winch 15, so as to rotate the mast 12 of the vertical horizontally and vice versa or to maintain the mast 12 in a given position can be carried out manually by an operator acting remotely on the winch, by means of a remote control for example.
  • these operations can also be more or less fully automated, so that the operator only controls the action to be performed (switching and / or holding in position), starting, stopping and blocking.
  • the rotation of the winch then being sequenced automatically by control means associated with appropriate means for determining at any time in which position is the mast 12.
  • control means may for example consist of sensors capable of determining the angular position mast compared to a reference, the vertical for example. Alternatively it can be means for measuring the cable length unwound by the winch.
  • the motorized mast according to the invention can advantageously be erected vertically or tilted horizontally without these tilting maneuvers, always sources of potential danger, requires the evolution of a human operator in the danger zone.
  • the sliding element consisting of the plate 111 and the guide rails 112 and 113, and the actuator constituted by the two cylinders 193 and 194 operates in the manner described in the foregoing text. As such it has a retracted form, illustrated by the figure 11 , for which the cylinders 193 and 194 are compressed, and an extended position, illustrated by the figure 12 , for which the cylinders 193 and 194 are relaxed.
  • the cylinders are further dimensioned to translate the moving part with sufficient energy to rotate the mast 12, without additional action.
  • the system apart from any external constraint, imposed by the first motor means for example, is in the deployed position.
  • the force applied by the mast causes the retraction of the movable part 192 and consequently the compression of the cylinders 193 and 194.
  • the mast finally reaches the vertical position.
  • the holding force of the mast in the vertical position, exerted by the winch 15 is released.
  • the cylinders then relax naturally, sliding the plate 111 and thus pushing the mast 12 until it the last reaches an inclination sufficient to ensure its natural tilt towards a horizontal position under the action of its own weight, the tilting being however controlled by the winch 15.
  • the second motor means may comprise, in addition to the sliding element 19, a complementary holding element for ensuring a mechanical locking action of the mast in a vertical position, independently of the action exerted by the first driving means .
  • this holding element may for example consist of a holding collar 119 composed of two half-collars, a fixed half-collar 1191 mounted on the fixed part 191 of the sliding element 19 and a free half-collar 1192 articulated by means of a first hinge 1193 and connected to the fixed half-collar 1191 by a second hinge 1194.
  • the assembly is provided with a closure 1195 comprising a quick-clamping bolt, equipped with a knurled nut or a cross nut 1196 allowing rapid closure of the collar 119 as soon as the mast 12 brought into vertical position is housed therein.
  • This complementary holding element has the particular advantage of allowing intervention on the winch 15 constituting the first motor means without having to position the mast 12 in a horizontal position, and therefore without having to lay down the equipment 31 carried by the mast. During the operation, the equipment remains in service during the operation.
