Definitions

  • the present invention relates to adaptable work machines, generally, at the rear of vehicles, more particularly motor vehicles, and it relates, more precisely, to machines of the articulated boom type carrying any work tool, such as a shovel, can be used for work involving the vehicle as a stable support platform.
  • Such vehicles also represent, by their engine group, a source of supply of energy, most often hydraulic, necessary for the operation of the machine.
  • an intermediate chassis carrying a carriage assuming the support of an arrow articulated on a horizontal axis.
  • the boom is mounted with the possibility of partial angular rotation on a vertical column.
  • the working machine is necessarily oriented either towards the inside of the loading platform to constitute a load transfer tool, or towards the outside and the rear to form a job.
  • the object of the invention is, precisely, to provide a solution to this problem by proposing a new articulated boom working machine, movable in elevation and in azimuth over 360 ° and adaptable to the rear of a vehicle.
  • the object of the invention can thus be used as a digging, excavation, earthmoving machine, being oriented towards the rear of the vehicle, but also, as a transhipment or load transfer machine. between the work area and the vehicle platform.
  • Another object of the invention is to provide reliable, simple and robust equipment which can be easily assembled or disassembled from a vehicle, without the latter resulting in a dead load penalty.
  • Another object of the invention is to provide a working machine which, after adaptation to the chassis of a vehicle, offers particularly stable and safe working and use conditions, even for personnel not specially qualified in driving. such materials.
  • the object of the invention is characterized in that it comprises: - an adaptation apron intended to be fixed to the rear of a vehicle, - a support frame that can be removably adapted to the bulkhead and defining a horizontal guide track perpendicular to the axis of the vehicle, - a mobile carriage adjustable in position on the track and carrying a vertical column guided in rotation and associated with a motor member for driving in rotation in both directions over an overall angular range of 360 °, - A support head fixed on the column and carrying an operating station and an arrow articulated on at least one horizontal axis and the end of which is provided with a working tool.
  • the invention also relates, as a new industrial product, to a vehicle, in particular a motor vehicle, equipped with a working machine according to the invention.
  • Figs. 1 and 2 show the rear part of a vehicle automobile 1, for example of the dump truck type.
  • the vehicle 1 comprises a chassis 2, the illustrated rear part of which bears on the ground S by an axle 3 and wheels 4.
  • the chassis 2 supports a bucket 5 which can be tilted laterally or rearwards.
  • the vehicle 1 is equipped, on the rear part of the chassis 2, with a working machine comprising an apron 6 for adaptation.
  • the structure of the apron 6 depends essentially on that of the vehicle platform, the chassis 2 and the shape of the bucket 5.
  • the adaptation apron 6 comprises a plate 7 which can be fixed, removably, on the chassis 2, in particular by means of bolts.
  • Figs. 3 and 4 show, more clearly, that the plate 7 of the adaptation apron 6 also includes two flanges 8 extending rearward by offering adaptation members 9. The length of the flanges 8 depends on the projection rear of the bucket 5 relative to the chassis 2, so as to place the members 9 externally at the normal rear space limit of the bucket 5.
  • the flanges 8 may be planar and parallel or have any other conformation made necessary by their own to the chassis 2.
  • the adaptation members 9 consist of notches 10, two in number for each flange and, generally, of vertical orientation.
  • the notches 10 are open at their upper part and, in the illustrated case, formed in vertical alignment.
  • Each flange 8 has, moreover, a hole 11 whose function appears in the following.
  • the assembly apron 6 is provided for supporting a chassis 12 comprising (fig. 3 and 5) a horizontal slide 13, rectilinear and perpendicular to the longitudinal axis of the vehicle.
  • the slide 13 is, more particularly, formed by two tubular beams 14 held parallel and in the same vertical plane by end struts 15.
  • the tubular beams 14 support, by their ends, two telescopic legs 16 which are preferably formed by tubular casings 17 each containing a jack 18, of the hydraulic type, with single or double effect.
  • the piston rod 19 of each cylinder is oriented, substantially, vertically and downwards and carries, at its end, a support sole 20.
  • the chassis 12 furthermore comprises means 21 for hooking with the adaptation members 9.
  • These means 21, two in number comprise, for each of them, two members 22 supporting two fixed axes 23 of horizontal orientation and relative vertical spacing corresponding to that existing between the bottoms of the notches 10 of the flanges 8.
  • the members 22 also comprise a hole 24 intended to be placed in coincidence with the corresponding hole 11.
  • the members 22 have between them a relative spacing corresponding to that existing between the flanges 8.
  • This engagement can be obtained by subjecting the chassis 12 to a horizontal approach movement and then to a relative movement in the downward vertical direction.
  • the axes 23 are thus brought simultaneously into the bottom of the notches 10 in which they are immobilized by the introduction of a dowel through the holes 11 and 24 in coincidence.
  • the above means thus make it possible to quickly adapt to a vehicle and also to quickly disassemble a working machine, by using only a single adaptation part constituted by the deck 6 of low relative mass.
  • the chassis 12 supports a carrying carriage 25 capable of being able to slide along the slide 13 while being able to be immobilized in any stable position on the latter.
  • the carrier carriage 25, illustrated by FIGS. 7 and 8, comprises a plate 26 provided with means 27 intended to cooperate with the slide 13.
  • the slide 13 is formed, as said above, by the members 14 which are formed to each comprise, in the same vertical plane and opposite to each other, a rule 28-29 which is fitted by a plywood 30 and by a platinum heel 31.
  • the counterplate 30 is constituted, as is known in the art, by a movable jaw associated with a jack making it possible to move it to achieve, in cooperation with the plate 26, a clamping or a tightening of the rule 28 and an immobilization of the carriage 25 in a determined relative position on the slide 13.
  • the plate 26 supports, by a head plate 32 and by two gussets 33, a barrel 34 of vertical axis.
  • the barrel 34 contains two smooth rings 35 ensuring centering with the possibility of rotation of a column 36 immobilized axially by an upper shoulder 37 and by a removable lower stop 38.
  • the column 36 rises above the head plate 32 and comprises a toothed pinion 39 angularly immobilized, in particular by a key 40.
  • the toothed pinion 39 cooperates with a drive motor member 41 which is designed to rotate the pinion 39 in one or the other of the two usual directions of rotation over a maximum overall angular range of 360 °.
  • the rotary drive member 41 is constituted by two jacks 42 mounted on the head plate 32.
  • the jacks 42 are interconnected by a rack 43 which cooperates, permanently, with the pinion 39.
  • the rack 43 is produced so that the maximum active stroke of each jack makes it possible to drive the toothed pinion 39 in both directions of rotation over a stroke substantially equal to 180 ° for each of them, from a neutral position corresponding to the median state of the pistons of the two cylinders 42.
  • Figs. 7 and 8 show that the head plate 32 supports a casing 44 protecting the pinion 39 by sheltering, for example, a reserve of grease.
  • the column 36 has an upper end part 36 a rising above the casing 44.
  • the end part 36 a supports a head 45 consisting of two cheeks 46 delimiting two bearings 47 for the horizontal articulation axis 48 of an articulated boom 49.
  • the boom 49 comprises an arm 50 and a pendulum 51 at the end of which a work tool 52, such as a bucket for carrying out excavations, earthworks, trenches, etc.
  • the arm 50 and the pendulum 51 are associated with jacks 53, 54 and 55 allowing their relative articulation, as well as that of the tool 52.
  • the cheeks 46 also support, by a bracket 56, a seat 57 as well as a manipulator 58 representing together a driving position.
  • the manipulator 58 makes it possible to control the supply of the hydraulic jacks 18, 42, 53, 54 and 55, as well as that of the jack associated with the clamp 30 for immobilizing the carriage 25 on the chassis 12.
  • the use of the working machine is carried out from the driving position, in the traditional way, after extension of the telescopic legs 16, so as to have a stable lateral support by means of the chassis 2 then constituting a platform of recovery.
  • Fig. 9 shows that the machine can work on a large area of the ground S, defined by the maximum projection of the articulated boom and by the movement of the carriage 25 along the slide 13, in cooperation with an angular offset controllable precisely by rotation of the column 36.
  • Another advantage of the arrangement according to the invention lies in the fact that the machine can be disposed in an out-of-service state by being oriented towards the inside of the bucket 5 on the bottom of which the tool 52 can bear.
