Definitions

  • ABSTRACT relates to a telescopic beam formed of two slidably mounted lengths and an organ for controlling the relative positions of these lengths relative to one another.
  • a locking apparatus permits selective locking and unlocking of the lengths.
  • One application is the construction of a tracked appliance with a variable gauge.
  • the invention relates to a telescopic beam formed of two slidably mounted lengths and an organ for controlling the relative positions of these lengths relative to one another.
  • Telescopic beams are already known which are provided with an automatic apparatus for locking and unlocking the various sliding lengths. Such beams are used, for example, in variable-gauge tracked vehicles or in mobile cranes with telescopic jibs.
  • the present invention is intended to remedy these disadvantages and enable the driver of the shovel to vary the gauge by himself, the gauge locking operations being carried out automatically,
  • the invention has applications other than the construction of an apparatus for varying the gauge of a tracked vehicle.
  • a telescopic beam comprising at least two lengths mounted to be relatively slidable, a drive organ which controls the relative positions of these lengths, means linking the drive organ between the said lengths and an apparatus for locking these two lengths in two of their relative positions, the locking apparatus comprising a lug which is mounted on one of the said lengths and two orifices which are formed in the other length, the lug being selectively engageable with and disengageable from these orfices, and the means linking the drive organ to the length provided with two orifices including an element which is movably mounted on this length and which bears two fingers of which one will enter the orifice engaged by the lug when the drive organ is to move the lengths relative to one another to bring the lug to the other orifice, the finger entering that orifice through the face of the length opposite to the face through which the lug entered that orifice, the controlling drive organ being operable to move the element relative to the length having two orifices when operated to vary the relative
  • the element is pivotably mounted on the length provided with two orifices, while the fingers are fixed on this element at equal distances from the pivot axis.
  • each orifice is provided with a chamfered sector which merges into the face through which the lug enters the orifice, the chamfered sectors of the two orifices being oriented towards each other.
  • the invention also relates to a variable-gauge.
  • This vehicle comprises a central chassis and two trackbearing frames, each of the said frames being connected to the central chassis by means of a telescopic beam as previously defined, while one of the lengths of the beam in question is fast with the central chassis and the other length of the said beam is fast with the corresponding frame.
  • FIG. I is a partial axial section of an embodiment of a telescopic beam in accordance with the invention.
  • FIG. 2 is a characteristic section of a constructional detail of the beam of FIG. 1;
  • FIG. 3 is a view in the direction of arrow F of FIG.
  • FIG. 4 is a partially sectioned plan of a tracked vehicle incorporating the beam.
  • the beam 1 shown in FIG. 1 comprises an outer length 2 and inner length 3, which is mounted slidably relative to the outer length 2 in the direction of the arrow 6.
  • An element 4 is mounted pivotably about an axis 5 on a support 6 welded to an external face 7 of a wall of the outer length 2.
  • This wall of the length 2 also has passing through it two orifices 8 which therefore emerge both on the external face 7 and on the face opposite to this external face, known as the introduction face 9.
  • Two fingers 10 are fast with the element 4, one of these fingers being introduced into one of the orifices 8 from which it has driven a lug 11.
  • the lug 11 is mounted slidably in a cylinder 12 fixed to the internal face of the wall of the inner length 3, opposite an orifice 13 passing through this wall.
  • a spring 14 is inserted between the cylinder 12 and the lug 11 and has the effect of pushing the said lug towards the introduction face 9.
  • the rod 15 of a ram 16 is pivoted on the element 4 about an axis 17, the cylinder 18 of the said ram I6 itself being pivoted about an axis 20 on an arm 19 fast with the length
  • the element 4 can have another position and, after pivoting, be arranged at 40. In this position, the first finger 10 which was previously introduced into one of the orifices 8, is disengaged at 10a from this orifice, while conversely the other finger is now arranged at in the other orifice 8.
  • This modification of the position of the element 4 follows the modification of the position of the axis 17 which has travelled to 170.
  • the end of the lug 11 is provided with a chamfer 21.
  • the orifices 8 have a chamfering sector 22 with which they merge on to the introduction face 9. This sector does not cover the whole of the edge of the orifice 8 which therefore also has a portion with a sharp edge 23. it will lastly be noted, in FIG. 1, that the chamfered sectors 22 of the two orifices 8 are oriented towards each other.
  • the appliance shown in FIG. 4 is a tracked hydraulic shovel, only the supporting framework of which has been shown for the sake of clarity.
  • This comprises a central chassis 24, which usually supports a pivoting turret, and two track-bearing frames 25.
  • Each frame 25 is mounted so that its position relative to the chassis 24 can be adjusted by means of two telescopic beams 1.
  • the telescopic beams 1 related to the two frames 25 are aligned in pairs, the inner lengths 3 of two aligned beams forming a single part.
  • half-gauges of each track are therefore, in this case, different and generally equal either to D1 or to D2.
  • the beam 1 is also in the extended configuration. Such a configuration is shown in FIG. 4, with regard to the beams 1 associated with the right frame 25.
  • the lug ll permits automatic selective locking of the lengths 2 and 3 in one or the other of their relative positions, while operation of the ram 16 automatically causes unlocking of the said lengths.
  • the chamfered sectors 22 facilitate introduction of the lug 11 into the orifices 8, just as the sharp right-angled edges 23 enable a sharp stop and exact maintenance of the position of one of the two lengths relative to the other to be obtained.
  • Telescopic beam comprising at least two lengths mounted to be relatively slidable, a drive organ which controls the relative positions of these lengths, means linking the drive organ between the said lengths and an apparatus for locking these two lengths in two of their relative positions, the locking apparatus comprising a lug which is mounted on one of the said lengths and two orifices which are formed in the other length, the lug being selectively engageable with and disengageable from these orifices, and the means linking the drive organ to the length provided with two orifices including an element which is movably mounted on this length and which bears two fingers of which one will enter the orifice engaged by the lug when the drive organ is to move the lengths relative to one another to bring the lug to the other orifice, the finger entering that orifice through the face of the length opposite to the face through which the lug entered that orifice, the controlling drive organ being operable to move the element relative to the length having two orifices when operated to vary the relative positions of the two lengths of the beam.
  • a beam in accordance with claim I in which the element is mounted pivotably on the length provided with the two orifices, while the fingers are fixed on this element at equal distances from the pivot axis of that element.
  • each orifice is provided with a chamfered sector which merges on to the face through which the lug enters that orifice in operation, the chamfered sectors of the two orifices being oriented towards each other.
  • a variable-gauge tracked vehicle comprising a central chassis and two track-bearing frames, each of the said frames being connected to the central chassis by means of a telescopic beam in accordance with claim 1, one of the lengths of the beam being fast with the central chassis and the other length of the said beam being fast with the corresponding frame.
