Definitions

  • the invention relates to a cable clamp for transporting or towing installation using a tractor overhead cable, a method for engaging / disengaging such a clamp to / from the corresponding cable, and a transport or towing installation using aerial cable. , especially two overhead cables.
  • the internal bearing surfaces of the jaws have a semi-cylindrical or almost semi-cylindrical shape so that in the clamped state the two jaws completely or almost completely enclose the cable.
  • the clamp grips the cable from above and the end lips of the jaws are flush with the underside of the cable.
  • end stations generally have two distinct zones: a vehicle arrival zone and a vehicle departure zone.
  • the clamps are stripped of the cables with a view in particular to allowing vehicle storage or embarkation / disembarkation respectively loading / unloading of passengers or goods stopped or at reduced circulation speed much lower than the cable travel speed.
  • the vehicles are released from the cables and travel on guide rails or other suitable tracks.
  • the reverse occurs so as to allow the circulation of vehicles or embarkation respectively the loading of passengers or goods at a standstill or at reduced speed much lower than the cable running speed.
  • the vehicles are engaged in the cables, then the clamps are engaged with the cables.
  • the fixed jaw having an internal bearing surface of generally semi-cylindrical shape which remains practically against the cable even when the clamp is in the loose state, it follows that to dissociate the cable from the clamp in the released state it is necessary to operate a combined double relative movement of the cable with respect to the clamp on the one hand: horizontal and transverse (that is to say normal to the middle part of the surface of the internal part of the fixed jaw) which has the effect to spread the cable and the fixed jaw, on the other hand vertical (that is to say in the direction of entry or exit of the clamp) until the cable completely escapes the internal space delimited by the jaws of the pliers.
  • horizontal and transverse that is to say normal to the middle part of the surface of the internal part of the fixed jaw
  • vertical that is to say in the direction of entry or exit of the clamp
  • the start / end zone comprising the clutch / disengage ramps, the cables, the running rails, the deflection means, is made up of several zones: a tightening / loosening zone, an association zone / dissociation, an engagement / disengagement zone.
  • each of the clamps progressively passes from the fully tightened state to the totally loose state or vice versa; in the association / dissociation zone, a relative movement of the clamp relative to the cable separates the clamp from the cable as a result of which no contact exists between the clamp and the cable, the clamp then being situated around and close to it of the cable, or vice versa, the clamp is secured to the cable by this relative movement of the clamp relative to the cable which establishes contact between the clamp and the cable; in the engagement / disengagement zone, the clamp is in the totally loosened state without surrounding the cable and is moved towards or away from the cable, as is the vehicle with which it is associated.
  • the means for relative deviation of the path of the cables with respect to that of the running rails are therefore placed essentially in the dissociation association zone and in the engagement / disengagement zone.
  • the invention therefore aims to remedy these drawbacks.
  • it offers a transport or towing installation with two aerial cables carrying parallel feeders parallel to each other and driven at the same speed with continuous movement, in particular thanks to end stations, pylons, support rollers, compression and / or guide having at least one vehicle or the like coupled in line by a hanger extending in the vertical plane of symmetry of the cables and articulated to a carriage carrying at least one pair of disengageable clamps for securing the carriage to the two cables in line by the top and for uncoupling the vehicle in the end stations by clearing the clamps, characterized in that the horizontal spacing E transverse to the right of the clamps between the two cables inserted in the clamps in the clamped and engaged state is less than the normal horizontal transverse spacing E 'of the cables imposed by the fixed structure of the installation (pylons, support rollers d e compression and / or guidance, end stations).
  • the invention also proposes a method for disengaging such a clamp in which during the second dissociation phase, a relative movement of the cable is carried out relative to the clamp exclusively in the vertical direction.
  • the invention also proposes a method for engaging two clamps respectively to each of the cables of a transport installation with two overhead cables parallel to each other and driven at the same speed in which the clamps are inserted between the separated cables, the cables are inserted into the internal space of the pliers, the pliers are associated with the cables, then each of the pliers is tightened around the cable in two stages, a first stage where the movable jaw is brought into contact with the lateral part of the corresponding cable, a second stage during which the cable is pressed against the fixed jaw by imposing a transverse approximation of the two cables; a method for disengaging at least two clamps which rigidly secure a vehicle to the cables of a transport installation with two overhead cables, the clamps having been previously engaged to the cables by a method according to the invention, in which during the phase of loosening of the clamps, the jaw of each of the clamps of the corresponding cable is moved aside, as a result of which the two cables return by elasticity to their normal spacing imposed by the fixed structure
  • the invention also proposes a transport installation using an overhead carrier-tractor cable comprising a cable clamp whose internal bearing surface of the fixed jaw comprises on the one hand a first support part in the form of a cylindrical sector. suitable for the section of the cable so that in the tightened state the first part follows a first section of the contour of the facing cable, and on the side of its end lip, a second part extending the first part and which at the 'tight state remains removed from the second section of opposite cable; the second part being at least partially and at least approximately flat, at least as far away from the second section as is the plane P extending the first part tangentially to its connection with the second part, at least partially and at least can near located in plane P; the first part having the shape of a cylindrical sector of approximately 90 °, without exceeding them; the spacing D between the free end of the first part and the free end of the lip being at most equal and roughly close to the diameter of the cable.
  • the invention solves, thanks to the particular shape given to the fixed jaw, and / or to the fact that the spacing of the clamps is slightly less than that of the two cables, the problem of the relative double deflection of the cable (s) ) relative to the clamp (s) in the association / dissociation zone.
  • the invention there is only vertical relative deviation without any particular problem, imposing by the delicate adjustment necessary for a horizontal deviation. This allows in particular to overcome the rollers with an inclined axis and the controlled technical difficulties which result therefrom.
  • FIGS. 6 to 10 illustrate the different phases of the clutch / clearing processes according to the invention.
  • a clamp 1 comprises, in a manner known per se, a clamp body 2 and two jaws, one fixed 3, the other movable 4 normally being in the engaged state where it is rigidly secured from above to a cable 5 which has a substantially circular cross section, the jaws being turned downwards and laterally enclosing the cable.
  • the two jaws 3, 4 comprise in known manner two end lips, respectively 6 and 7, flush with the lower base 8 of the cable 5 in the clamped position to allow passage over the cable support rollers 5 smoothly and have a slight projection on the upper part 9 of the cable 5 which does not obstruct the passage under the compression rollers.
  • the movable jaw 4 is articulated in a known manner on an axis 10 carried by the body 2 and which, in the engaged state, extends parallel and above the cable 5.
  • Each jaw 3, 4 has an internal bearing surface 11, 12, these surfaces defining an internal space 13 of the clamp 1.
  • the cable 5 is included in the internal space 13 and the surfaces 11, 12, are at least partly in contact with cable 5.
  • the internal bearing surface 11 of the fixed jaw 3 of a clamp comprises on the one hand a first support part 14 on the cable 5 in the form of a cylindrical sector suitable for the section of the cable 5 so that 'in the clamped state, the first part 14 marries a first section 15 of the cable outline 5 opposite, and on the side of the end lip 6, a second part 16 extending the first part 14 and which in the state tight remains apart from the second section 17 of facing cable outline.
  • This second part 16 is at least partially and at least approximately flat. It is at least as far apart from the second section 17 as it is from the plane P extending the first part 4 tangentially to its connection 18 with the second part 16.
  • this second part 16 is at least partially and at least approximately located in the plane P, or even as shown in FIG. 2, substantially plane and located in the plane P (shown partially in dotted lines in FIG. 2).
  • the first part 14 for bearing on the cable 5, in contact with the cable 5, has the shape of a cylindrical sector of approximately 90 °.
  • This cylindrical sector advantageously is at most 90 °, but may be less than 90 °, in which case the second part 16 is more distant from the second section 17 than is the plane P.
  • the spacing D between the lip d end 7 and the end lip 6 is in the tightened state, less than the diameter of the cable 5, so that the cable cannot escape from the internal space 13 of the clamp 1 when the latter is in the tight and engaged state.
  • the internal bearing surface 12 of the movable jaw 4 has the shape of a cylindrical sector suitable for the section of the cable 5 so that in the tightened state, the entire movable jaw conforms to the section 19 of the cable outline in look and fully cooperate with the cable.
  • This internal bearing surface 12 has the shape of a cylindrical sector between 90 and 180 ° and preferably between 120 and 150 °.
  • the clamp 1 cooperates in the clamped state with the cable 5 on a cylindrical sector less than 270 ° but greater than 180 °, preferably between 210 and 240 °.
  • the internal bearing surfaces 11, 12 are advantageously connected in the clamped state opposite the upper part 9 of the cable without leaving a section of this upper part 9 of the cable 5 which does not cooperate with the clamp.
  • the two surfaces 11, 12 therefore conform to a section of cable formed from sections 15 facing the first part of the surface 11 and 19 facing the surface 12, according to a continuous cylindrical sector between 210 and 240 degrees.
  • the longitudinal horizontal direction is the direction of the cable 5. It will be noted that this direction is not in practice always horizontal, although it is referred to as longitudinal horizontal for the sake of simplicity, because it can be more or less strongly inclined relative to the horizontal of the place according to the route given to the cable, a route which depends in particular on accidents on the ground and / or the function fulfilled by the transport or towing installation concerned.
  • the horizontal transverse direction is the direction which is horizontal in the absolute and perpendicular to the direction of the cable 5. These two directions define a so-called horizontal plane although in practice this plane is not necessarily always truly horizontal in the absolute, only the transverse horizontal direction being horizontal in absolute terms.
  • the vertical direction is the direction perpendicular to this plane.
  • the horizontal plane is the plane containing the two cables.
  • this plane is either effectively horizontal if the longitudinal horizontal direction is effectively horizontal or inclined more or less sharply depending on the terrain and the path of the cables.
  • the invention also relates to a method for disengaging a clamp from the corresponding cable, that is to say a method making it possible to loosen a clamp parallel to the clamped state and rigidly secured to the cable, then to dissociate the clamp from the cable by removing any contact between the clamp and the cable and finally to disengage the cable from the clamp so that the clamp and the cable are completely independent of each other and can no longer interfere with each other.
  • a method for engaging a clamp to a cable makes it possible to engage the cable in the internal space of the clamp so that they can interfere with each other, to associate the cable with the clamp by establishing contact between the cable and the clamp, then tighten the clamp around the cable, after which the clamp is rigidly secured to the cable.
  • a method for disengaging a clamp 1 according to the invention from the corresponding cable 5, comprises in known manner an initial phase of loosening of the clamp 1 during which the jaws 3, 4 are loosened from the clamped state where the clamp is rigidly secured to the cable 5, an intermediate phase of dissociation of the clamp 1 from the cable 5 during which all contact between the cable 5 and the clamp 1 is removed to separate the cable 5 from the clamp 1, the cable 5 being however still included in the internal space 13 of the clamp 1 at the end of this dissociation phase, but being able to scroll at a speed different from the speed of advance of the clamp 1 which can possibly even be completely stopped, a phase final disengagement of the cable 5 from the clamp 1 during which the cable 5 is removed from the clamp 1, out of its internal space 13 so that it can no longer interfere with it.
  • a relative movement of the cable 5 is carried out relative to the clamp 1 exclusively in the vertical direction. Thanks to the previously described shape of the clamp 1 according to the invention, it is not necessary to make a relative movement in the horizontal transverse direction of the cable 5 relative to the clamp 1 to dissociate them. Indeed, the fixed jaw 3 of the clamp 1 has an internal bearing surface 11, the second part 16 and therefore the end lip 6 of this fixed jaw 3-is spaced from the cable.
  • the invention relates more particularly to a method for dissociating a cable from an overhead cable transport or towing installation with a disengageable clamp allowing the engaged state to secure a vehicle or similar to this cable, in which mainly displaces the clamp vertically and upwards and in that the cable is left with a straight path.

Conversely, during dissociation, these means 28 vertically separate the clamp 1 in the loose state and the cable 5, eliminating any contact between the clamp 1 and the cable 5. At the end of the phase dissociation as we understand it, the cable 5 is located in the internal space 13 of the clamp 1 and therefore the vehicle is not yet completely uncoupled.

Verfahren zum Entkuppeln von mindestens zwei Zangen, die ein Fahrzeug starr mit jeweils einem Seil einer Vorrichtung zum Transport mit zwei hängenden Seilen verbinden, nach einem der Ansprüche 1 bis 4, wobei die Zangen vorher an die Seile nach einem Verfahren nach einem der Ansprüche 5 oder 6 angekuppelt worden sind, dadurch gekennzeichnet, daß man während der Phase der Öffnung der Zangen aus dem geschlossenen Zustand in dem sie starr mit den Seilen verbunden sind, die bewegliche Backe (4) jeder der beiden Zangen vom entsprechenden Seil entfernt, wobei die beiden Seile durch die Elastizität in ihren normalen Abstand zurückkehren, der durch die feste Struktur der Vorrichtung (Maste, Stützrollen (22), Druckrollen und/oder Führungsrollen) gegeben ist, und der geringfügig größer ist, als der Transversalabstand der Zangen, wodurch sich ein Teil einerseits vom anderen und andererseits von der feststehenden Backe der Zangen entfernt.
