Definitions

  • the present invention relates to a device for guiding one or more hoses at the end of an articulated mast of a lifting device and a lifting device provided with such a device, in particular for digging trenches in the ground.
  • This device comprises an articulated mast at the top end of which a chassis is suspended by means of cables. Milling drums, mounted at the bottom of the chassis, are rotated and break up the ground allowing the chassis to descend into the ground to excavate.
  • a hose connected to the chassis allows the cuttings to be raised from the vicinity of the milling drums to the ground surface.
  • the hose extends vertically from the chassis to the high end of the articulated mast where it bends to extend substantially parallel to the mast, to a reel with horizontal axis located next to the mast.
  • a guide device is provided to give the hoses a progressive curvature limiting, as far as possible, excessive stresses on the hoses.
  • the mast is articulated so as to be able to go up and down, that is to say by changing the inclination, it is understood that the hoses bend over a section of variable length which increases with the height at which it is located the high end of the mast.
  • the hoses when the mast is in a substantially horizontal low position, the hoses pass from a vertical orientation to a horizontal orientation by winding on the guide device at the end of the mast over about a quarter of a turn. , i.e. 90 °, while, when the mast is in the high position while being inclined by approximately 45 ° with respect to the horizontal, the hoses pass from a vertical orientation to an orientation inclined at 45 degrees by winding on about three-eighths of a turn, or 135 °, on the guide device.
  • the guiding device must come into contact with the hoses so tangential, both in the vertical part of the hoses and in their part parallel to the mast.
  • the guide device 1 must extend over 135 ° so as to properly support the hose 2 when the mast 3 is in the high position.
  • the hose 2 no longer winds up more than 90 ° on the guide device 1, which then comprises an unnecessary portion of 45 ° s' extending downwards, which hinders reassembly of the chassis 4.
  • the chassis 4 can therefore only go up to a distance h from the mast 3.
  • a guide device 1 ′ shown in FIG. 3 has hitherto been used, which is dimensioned so that it extends only over a quarter turn, ie 90 °, which allows to raise the chassis 4 as much as possible without it coming up against the lower part of the guide device 1 'when the mast 2 is in a horizontal position.
  • the hose 2 is poorly guided, because the guide device 1 ′ is not tangent to the vertical part of the hose 2, which causes a break. C of the hose, and generally premature wear of the hose.
  • the present invention provides a hose guiding device which solves the problems mentioned above and which is particularly simple and economical.
  • the present invention relates to a device for guiding at least one flexible hose at the end of a mast articulated around a first fixed articulation axis, said flexible hose comprising a part extending along the mast and a part dipping downwards from the end of the mast, the device comprising a support member arranged at the end of the mast to support the hose by giving it a curvature capable of preventing any breakage of said hose at least in the low position of the mast, characterized by the fact that the support member extends over a length sufficient to support the hose in the highest position of the mast without said hose breaking and by the fact that the support member is mounted pivoting on the one hand on the mast around a first articulation axis and on the other hand on a rigid connection means around a second articulation axis, said rigid connection means being itself articulated around a second fixed articulation axis, the first and second fixed articulation axes and the first and second pivot axes being located at the four vertices of a
  • the guide device comprises a support member which has the length necessary to suitably support the hose or hoses without them breaking even when the mast is in the high position, but of the fact that this support member remains parallel to itself, the disadvantage does not occur that, when the mast is in the low position, the support member protrudes at the bottom of the mast and hinders reassembly of the chassis to which the hoses are connected.
  • the support member of the device according to the invention has, of course, an excess portion which does not support the hoses, but this excess portion is located in the upper part of the device and does not in any way interfere with the reassembly of the chassis.
  • the device according to the invention ensures proper guidance of the hoses and does not cause any discomfort during reassembly of the chassis.
  • the support member is mounted on the mast so that its excess portion, in the sense defined above, penetrates into the thickness of the mast when the mast is in the low position .
  • the rigid connection means which connects the support member to the second articulation axis consists of a bar substantially the same length as the mast, which extends parallel to the latter .
  • the support member is of the roller type, that is to say that it has a succession of rollers with axes parallel to each other and perpendicular to the axis of the hose, said rollers being arranged, seen sideways, following an arc.
  • the present invention also relates to a lifting device provided with a device as described above and in particular a lifting device for digging trenches in the ground using milling drums of the type comprising a platform supported by a running gear, a lifting mast articulated on the platform, a chassis suspended from the high end of the mast, rotationally driven milling drums mounted on the lower part of the chassis, at least one reel with horizontal axis located on the platform next to the mast , supporting a hose for raising the cuttings from the vicinity of the milling drums to the ground surface and one or more hydraulic hoses, said hoses extending from the upper part of the chassis to the reel being vertical between the chassis and the high end of the mast and parallel to the axis of the mast between the high end of the mast and the reel, characterized in that it also comprises a guide device as described above at the high end of the mast to give the hoses an appropriate curvature avoiding any breakage of the latter at the high end of the mast.
  • FIGS. 5 and 6 The schematic representation of the device according to the invention given in FIGS. 5 and 6 makes it possible to understand the operating principle of this device.
  • the set of rollers 5, of which FIG. 5A provides a sectional view of a roll and which constitutes a support member within the meaning of the invention, is mounted at the top end of the mast 6 around an axis of pivoting 7 substantially horizontal and perpendicular to the longitudinal axis of the mast.
  • the support member 5 is preferably constituted by two parallel plates 5a between which are fixed axes on which are mounted the rollers 5b themselves.
  • the axes of the rollers 5b are arranged, in projection on the plates 5a, in an arc.
  • the mast 6 is itself articulated on a base 8 secured to a platform 9, around an axis 10 of articulation parallel to the axis 7.
  • a rigid bar 11 is articulated around an articulation axis 12, parallel to the axes 7 and 10.
  • the bar 11 has substantially the same length as the mast 6.
  • the bar 11 is connected to the roller assembly 5 by a pivot axis 13 parallel to the axes 7, 10 and 12.
  • the four axes 7, 10, 12 and 13 are located at the four vertices of a parallelogram, so that, during movements of inclination of the mast, the plane containing the axes 7 and 13 remains parallel to the plane linked to base 8 and defined by axes 10 and 12.
  • roller assembly 5 remains parallel to itself whatever the inclination of the mast 6.
  • the hose 2 is wound on 135 ° on the roller assembly, which is tangent to the flexible in the vertical part and in the part parallel to the mast of said flexible.
  • the roller assembly 5 When the mast is horizontal, as shown in FIG. 6, the roller assembly 5 is always tangent to the hose, in the vertical part and in the horizontal part of the latter, but an upper part of the roller assembly 5, which extends over 45 °, is not used for guiding the hose.
  • the device according to the invention is capable of guiding the hose by giving it a progressive curvature capable of preserving it from any premature wear, while keeping the compactness of the lifting device on which it is installed.
  • Figures 7 and 8 show an example of an apparatus for digging trenches in the ground using a guide device according to the invention.
  • This device comprises a running gear 14 on which rests a platform 15 supporting a reel with horizontal axis 16, a base 17 and thrust jacks 18 which act on a mast 19 articulated on the base 17.
  • a set of rollers 20 with horizontal axes parallel to each other and arranged substantially in an arc is mounted to pivot at the end of the mast remote from the reel 16, being connected to the base 17 by a rigid metal bar 21 pivotally mounted on the one hand to said set of rollers 20 and on the other hand to the base 17.
  • FIG. 7 reference numerals 7, 10, 12, 13 have been plotted corresponding to the pivot and articulation axes of FIGS. 5 and 6.
  • the mast and the bar are dimensioned and positioned so as to constitute the two opposite sides of a deformable parallelogram by which the rollers 20 remain parallel itself.
  • the hose rests on the entire length of the roller assembly, about 135 °.
  • the roller assembly In the low position of the mast, as shown in Figure 7, the roller assembly has an excess portion which is located in the thickness of the mast and does not interfere with the reassembly of the chassis (not shown).
