Definitions

  • the invention relates to a bridge-laying machine of the type comprising at least one span arranged on a chassis and members adapted to deposit the bridge at the front of the machine.
  • a first type of machine is suitable for launching "scissor" bridges whose range is of the order of twenty meters.
  • the spans are transported in two sections folded one on the other around a central articulation, and are deployed by describing a rotation.
  • This mode of implementation has a major drawback in that during the rotation, the spans reach a significant height. Indeed, the bridge can only be deployed in open ground because of the necessary headroom. In addition, this rotation increases the risks of vulnerability.
  • a first technique in particular described in FR-A-2,477,599, FR-A-2,577,953 and FR-A-2,577,863, consists in using an extendable manipulator arm coming to bear by its free end on the bank to be reached and on which the bridge is made to slide.
  • This technique makes it possible to solve the problems of balance of the machine during the removal phase.
  • it has the major drawback of requiring an arm the same length as the bridge, which is therefore heavy and bulky, which goes against the objectives of mobility and ergonomics generally sought after.
  • a third technique notably described in a variant in FR-A-1,553,517 consists in using an arm of fixed and limited length on which the bridge is made to slide.
  • This arm is initially subjected to a rotation so as to tilt the bridge and allow the removal of its front end on the opposite bank of the breach. It further comprises an articulated front section allowing, under the effect of a jack, to deposit the rear end of the bridge on the bank where the machine is located.
  • This technique partially overcomes the drawbacks of the first two techniques described above.
  • the rotation of the arm is at the expense of the living space of the cabin and poses ergonomic problems.
  • the arm must have a hinged section for removing the rear end of the bridge.
  • the present invention relates to a bridge-laying machine of the type described above, overcoming the drawbacks thereof and has for this purpose the objective of providing a bridge-laying machine allowing good visibility of the drop-off site and comprising a cabin of appreciable volume from an ergonomic point of view.
  • Another objective is to provide a bridge-laying machine equipped with a simplified manipulator arm, devoid of any specific member for removal.
  • This forward tilting of the manipulator-cabin arm assembly provides many advantages.
  • the volume of the cabin is not affected by the rotation of the arm, which is particularly appreciable from an ergonomic point of view.
  • visibility to the drop-off site is improved compared to known vehicles.
  • the design of the arm is very simplified since the latter does not include any specific equipment contributing to the implementation of the bridge.
  • the means for tilting the cabin and the manipulator arm comprise at least one jack coupled respectively to the chassis and to said cabin.
  • This longitudinal translational movement of the arm makes it possible to produce a machine of reduced length in transport condition, while allowing sufficient rotation of the arm for removing the bridge.
  • the bridge-laying machine shown in the figures comprises a road chassis 1 on wheels 2 carrying a bridge broken down into two superimposed spans, lower 3 and upper 4, with a lattice structure.
  • Each of these spans comprises two parallel raceways 3a, 3b, 4a, 4b connected by spacers 5.
  • a cabin 6 separated into two lateral compartments 6a, 6b secured to a central frame 7 articulated on the chassis 1 so as to be able to tilt forward.
  • This tilting is controlled by a jack 8 articulated, on the one hand, on the chassis 1 and on the other hand on said frame 7.
  • This manipulator arm 9 carrying the spans and arranged so as to be positioned between the raceways 3a, 3b, 4a, 4b of these spans 3, 4.
  • This manipulator arm 9, of generally shaped section rectangular parallelepiped, has an upper face comprising two lateral recesses defining two upper planar rolling surfaces 10. It is also provided with two longitudinal members 11 arranged longitudinally, each on one of its lateral faces, and comprising horizontal bearing faces defining two other lower flat rolling surfaces.
  • the upper 4 and lower 3 spans are in turn provided with upper and lower rollers 12 distributed longitudinally along these spans and arranged opposite the nodes of the trellis structure so as to come into abutment respectively on the upper rolling surfaces 10 and lower 11 of the manipulator arm 9.
  • this device for longitudinal guide of the spans 3, 4 on the manipulator arm 9 makes it possible to obtain a significant gain in mass compared to the known devices for which the spans are provided with rails. guide inside which are housed rollers integral with the arm.
  • the front end of the manipulator arm 9 further comprises an inclined ramp 13 arranged to cooperate with an upper roller 12 of the lower span 3, in order to pivot this span and obtain a bridge provided with a counter-jib. , as we will see later.
  • the manipulator arm 9 also comprises two lower lateral slides 14 inside which are housed guide pads 15 integral with the frame 7 and adapted to ensure the longitudinal guidance of this arm 9 and to prevent it from tipping over when it is cantilevered at the front of chassis 1.
  • Horizontal guide rollers 16 integral with the frame 7 are also housed in the slides 14 so as to ensure transverse guidance of the manipulator arm 9.
  • the displacement means associated with this manipulator arm and adapted to position it in cantilever at the front of the chassis 1, comprise a rack 17 integral with said arm and extending along the latter, and a drive pinion 18 associated driven by a geared motor 19, and against which the rack 17 is pressed by a support counter-roller 20.
  • the manipulator arm also incorporates means for driving the spans 3, 4 adapted to move them longitudinally along this arm.
  • These drive means comprise a horizontal endless chain 21 driven by a motor pinion 22, arranged to mesh punctually on fingers 23 arranged at regular intervals under the spacers 5 of the spans 3, 4.
  • These fingers 23 associated two by two have the shape of a yoke in which are housed horizontal drive studs 24 projecting laterally on either side of the links of the drive chain 21. As shown in the figures 12, 13 and 14, these fingers 23 and these studs 24 are further adapted to dissociate when the inclination of the manipulator arm 9 relative to the spans 3, 4 is greater than a determined value.
  • a pivoting arm 25 articulated on said frame and provided with means for hooking the upper span 4. These hooking means are intended to hold the upper span 4 during transport and during displacements of this span intended to bring it into the extension of the lower span 3.
  • these attachment means comprise jaws 26 adapted to close on the lower roller 12 at the end of the upper span 4, when the latter comes into said jaw, during sliding towards the rear of this span along the manipulator arm 9.
  • a blocking member also makes it possible to keep the jaw 26 in its closed position and to release its opening on command so as to allow the upper span 4 to slide forward.
  • This blocking member consists of a lock 27 pushed by a spring 28 and of a shape adapted to be housed in an external recess 26a of the jaw 26. The withdrawal of this lock 27 is also controlled by a jack 29.
  • the pivoting arm 25 shown in FIG. 8 in the transport position and carrying these hooking means is adapted to make the upper span 4 slide longitudinally towards the rear and rotate it so as to bring it in line with the lower span 3, pivoting during which this upper span 4 is supported on a support 30 projecting from chassis 1.
  • this pivoting arm 25 comprises a first jack 31 carrying the hooking means and arranged so as to raise the rear end of the upper span 4 (FIG. 9).
  • the body of this first cylinder is fixed on an intermediate arm 32 articulated on the chassis 1 so as to be able to pivot backwards under the action of a second cylinder 33 articulated on the chassis 1 and on this intermediate arm 32 (FIG. 10).
  • a third jack 34 articulated, on the one hand, on the end of the rod of the second jack 33 by means of a part 35 fixed on the intermediate arm 32 and, on the other hand, on this intermediate arm 32, finally allows during its deployment to increase the rotational stroke of the upper span 4, so as to release it.
  • this third cylinder 34 is retracted, it then makes it possible to bring the upper span 4 back into a substantially horizontal position.
  • cross-sections 3, 4 carried by this machine comprise junction faces 3c, 4c inclined so as to define a dihedron open downwards when said cross-sections are positioned end to end.
  • junction faces 3c, 4c are furthermore provided with centering, articulation and locking means making it possible, at first, to articulate the cross-sections 3, 4 in the upper part and, secondly, to lock them in part. low, after the pivoting of the lower span 3 due to its passage on the inclined guide ramp 13.
  • the centering means are distributed transversely over the length of the junction face 3c, 4c of the spans 3, 4 in the upper part thereof. As shown in Figure 16, they consist of a plurality of horizontal axes 36 secured on the junction faces 3c, 4c of the spans 3, 4 and, for each of these axes 36, a yoke 37 secured on the junction face 4c, 3c of the other span 4, 3 in the conjugate position of said axis.
  • the articulation and locking means comprise several assemblies as shown in Figures 17 and 18, each comprising a horizontal axis 38 fixed on the junction face 3c, 4c of a span 3, 4 and a jaw 39 secured on the junction face 4c, 3 of the other span 4, 3, in conjugate position of said axis, so as to close on the latter.
  • a locking member also makes it possible to maintain the jaw 39 in its closed position.
  • This blocking member consists of a bolt 40 pushed by a spring 41 and of a shape adapted to be housed in an external recess 39a of the jaw 39.
  • the manipulator arm 9 is, moreover, laterally provided with rolling surfaces having an inclined ramp 42, in the appropriate position, on which a roller 43 moves connected to the lock 40 by a linkage 44 adapted to drive the backward movement of this lock 40 when this roller 43 rises on this ramp 42.
  • the spans 3, 4 comprise two articulation assemblies in the upper part, each arranged on a raceway 3a, 3b, 4a, 4b and each comprising their own unlocking roller 43.
  • Each raceway 3a, 3b, 4a, 4b comprises two twin assemblies arranged laterally on either side of this raceway and connected by a linkage 45 so as to be actuated by a single unlocking roller 43.
