Definitions

  • the present invention relates to telescopic column structures for excavating trenches and foundations.
  • the improvements relate to telescopic column structures which serve to sustain, guide and drive buckets, drills and other tools normally used in excavating trenches, foundations and similar.
  • telescopic columns In the field of digging linear trenches, foundations and perforations by columns, telescopic columns may be used which permit digging to a great depth.
  • the telescopic columns are equipped with buckets, drills or similar means for the purpose of executing the required excavation.
  • the telescopic columns are formed of a plurality of columns insertable within each other and made to extend for use according to the depth of the job.
  • Such a telescopic column is known from FR-A-2313510.
  • a column structure is described in FR-A-2311921 which includes digging assembly supported on a platform rotatable about a horizontal axis and about the axis of the digging tool and able to be extended away from the crawler track which carries said structure.
  • the present telescopic column structure is directed to the system of installing, anchorage and displacement of the columns.
  • the present invention improves the manoeuvrability of the telescopic columns expanding thus their field of utility.
  • One further object of the invention is to permit the digging of excavations which are located laterally of the structure, without difficulties nor complicated auxiliary manoeuvres of the support means.
  • 10 generically indicates the machine for excavating the foundation 11 stationed on the terrain 12 and provided in the example with crawler tracks 13; 14 is the body of the machine which contains the drive system; 15 is the telescopic column which is displaceable forward (or backward) until it reaches the position 115, and laterally displaceable until it at least reaches the angular positions 215 and 315 (Fig.
  • 16 is the platform sustained by the struts 17 and a tie or ties 19; 17 are the platform support struts which are anchored at 129 to the machine's body 14 and at 29 to the platform 16; 18 is at least one jack which serves to horizontally position said platform 16; 19 are the ties which counteract the struts 17 with which they cooperate at 29 to sustain in the platform 16; 20 is a cable which permits movement of the elements of the telescopic column downward; the said cable runs on a pulley 30, then on a pulley 31 (both provided on the platform 16) and then on pulley 25 provided on the front of the central element 228 of the telescopic column 15 to eventually rise and terminate at 24 in the external fixed body of the telescopic column; 21 is an excavating tool such as a bucket of a known type integrally connected to base 26 provided in the frontal body of a central element 328.
  • the actuation of the bucket 21 is done, for instance, by means of the hydraulic conduits 35 wound on a drum 23.
  • 22 is a tie bar (or bars) which connects the position 29 of the platform 16 with the top of the fixed body of the column 15 in order to create a sturdy articulation system
  • 23 is the drum for winding and unwinding the conduits 35 which actuate the bucket 21, such a drum is connected in a known way to the operating plant which pilots the oil and is provided in the machine's body 14
  • 24 is the anchorage of the cable 20 on the external fixed body
  • 25 is the transmission pulley provided on the internal central element 328 of the telescopic column 15
  • 26 is the base on which is provided the bucket 21; said base is situated on the central internal element 328 of the telescopic column 15
  • 27 is the support member which horizontally restrains the column and is rotatable, and whose rotation can be obtained either by means of a motor or a jack 32 as shown in the example; the support member 27 is sustained and guided by the platform 16; 28, 128, 228, 328 are the various components forming the telescopic column 15.
  • the element 28 of the example is slidable in the external fixed body of the columns 15 and the element 328 is central while the elements 128 and 228 are intermediate.
  • 29 is the location of attachment means of the platform 16 where at least the struts 17 are anchored;
  • 30 is the posterior pulley on which runs the cable;
  • 32 is, in the example, the jack which causes the partial rotation of the support member 27;
  • 33 is the attachment means of the jack 32 to the platform;
  • 35 are the hydraulic actuation conduits, which are known, of the bucket 21.
  • the telescopic column is advantageously laid on the ground (Fig. 1, position 415) then hooked at 219 and the braces 19 are connected at 29.
  • the cable 20 is also connected.
  • the telescopic column can be moved between position 15 and 1 15 of Fig. 1.
  • the tool 21 is installed on the plate 26 and connected to the hydraulic conduit as the latter is withdrawn from the drum 23.
  • the cable 20 is relaxed until the column elements descend lowering thus the tool 21.
  • the digging tool 21 is then actuated in the usual manner.
  • the cable 20 is withdrawn in the usual way which causes the withdrawal of the columns elements.
  • the telescopic column is placed in position 215, and then, by means of jack 32, is moved into position 315.
