Definitions

  • the invention relates to a disengageable coupling pliers of a vehicle to a towing cable, extending below the vehicle, from a dedicated transport facility, comprising a clamp body fixed under the bottom of the vehicle, a fixed jaw carried by this body projecting downwards, a movable jaw cooperating with the fixed jaw to grip the cable in the coupling position and to allow the release of the cable down in the uncoupling position, and a control mechanism having a toggle with two connecting rods connected by a toggle pin, to move the movable jaw in the cable coupling and uncoupling position.
  • Cable traction of vehicles in a own site transport has many advantages, particularly simplicity and reliability, but it requires the use of disengageable pliers, for coupling and uncoupling the vehicle from the cable, the opening and closing are perfectly ensured, in order to avoid any risk of sliding of the clamp on the cable and all false maneuver.
  • French patent application No. 2,719,012 describes pliers of the kind mentioned, having a pair of worn jaws by a keel. This clamp cooperates with a cable located below of the track and it's bulky and complicated.
  • the present invention aims to allow the realization a reliable clamp of simple structure, capable of being housed under the vehicle and cooperate with a cable, extending at or above the track.
  • the clamp according to the invention is characterized in that the jaw mobile is pivotally mounted on an axis parallel to the housing of the cable clamped by the jaws and is rigidly secured to a lever to constitute a bent lever of the first kind, the end of the bent lever, opposite the movable jaw, being articulated to one of the knee braces, that the other of said toggle links is rotatably mounted on a fixed axis of the body, parallel to said pivot axis of the lever bent, so that the bent lever and said connecting rods wrestle in parallel or overlapping vertical planes and that said toggle links are almost aligned and horizontal in cable clamping position.
  • the angled lever is coupled to a toggle, which provides stable opening and closing positions of the clamp, in particular by a slight overshoot of the neutral position closing.
  • the kneepad includes a telescopic connecting rod, associated with a compression spring, advantageously constituted by a stack of elastic washers, which stress the telescopic rod in extension.
  • One end of the knee brace is articulated at a fixed point while the opposite end is articulated with the bent lever.
  • a jack cooperates with the knee switch to control the opening and clamp closure
  • the jaws are made up of easily removable independent parts and exchangeable, the same clamp can be fitted with different types of jaws, especially for section cables different.
  • a track 10 on its own site, consists of two running tracks 14.15, each associated with a running track guide 16.17.
  • the vehicles 18 traveling on track 10 are provided with running wheels 19 and guide wheels 20, which cooperate with the rolling tracks 14,15 and the guide tracks 16.17.
  • These 19,20 wheels are bandaged pneumatic, but it is clear that the invention is applicable to railways and other types of vehicles.
  • a cable tractor 11 extends in the axis and above the track 10, in being guided by support pulleys 13 and being driven by a motor (not shown). At the bottom of the vehicle 18 is fixed a clamp 21, capable of enclosing the cable 11 for connect the vehicle to this towing cable.
  • the clamp 21 has a fixed jaw 22 and a movable jaw 23, carried by a clamp body 24 fixed under the bottom of the vehicle 18, so that the pair of jaws 22,23 protrudes towards the low and allows the engagement of the cable 11 between the jaws 22,23 and its release by a relative movement of rise and descent.
  • the movable jaw 23 is pivotally mounted on an axis fixed 25, integral with the gripper body 24 and disposed above the cable housing 11, confined by the jaws 22,23 in position coupling.
  • the movable jaw 23 is secured and extended by a lever constituting a bent control lever 26.
  • the end 27 of the bent lever 26, opposite the movable jaw 23, is articulated to a first connecting rod 28 of a toggle joint 29, the second connecting rod 30 of which is rotatably mounted on an axis fixed 31.
  • the first connecting rod 28 is in two parts telescopic, between which is inserted a spring compression 32, constituted, for example by a stack of elastic washers, which urge the connecting rod 28 in extension.
  • the extension stroke of the telescopic link 28 and therefore of relaxation of the spring 32, is limited by stops 12.
  • the two connecting rods 28.30 are connected by the axis 33 of the knee pad 29, which, in the extended and overtaking position from the neutral point of the toggle joint 29, cooperates with a fixed stop 34.
  • the toggle 29 In this extended position the toggle 29 is substantially horizontal above the axis of articulation of the bent lever 26.
  • the second connecting rod 30 carries an arm transverse 35, to which the rod 36 of a jack 37 is articulated, for example hydraulic or pneumatic, to control extending or breaking the knee brace 29.
  • the bent lever 26 In the example illustrated by Figures 4 to 6 the bent lever 26, the second connecting rod 30 and cylinder 37 are split to constitute a symmetrical assembly of great operational safety. he it is clear that each of the connecting rods 28.30 can have a spring 32.
  • the assembly is arranged so that in the position extension of the toggle joint 29, represented in FIGS. 2.4 and 6, the jaws 22, 23 grip the cable 11 with a force of tightening corresponding to that of spring 32, multiplied by ratio of the arms of the angle lever 26.
  • the neutral position of the knee pad 29 is slightly exceeded and this position extension is thus a stable closed position of the clamp 21.
  • the opening of the clamp 21 is controlled by the jack 37, which rotates the second connecting rod 30 in the opposite direction clockwise in Figure 2, thus causing the breaking of the toggle joint 29 and the pivoting of the lever angled 26 counterclockwise.
  • the movable jaw 23 is moved to the open position of the jaw 22,23, shown in FIG. 3.
  • the movable jaw 23 and the fixed jaw 22 are parts independent fixed in a removable way, for example by centering pads 38 and screws (not shown) respectively to the bent lever 26 and to the clamp body 24.
  • the 22.23 worn jaws can thus be easily replaced by new jaws and the same clamp can be used for cables of different section by choosing suitable jaws.
