Definitions

  • ABSTRACT Handling and digging apparatus comprises a chassis, a jib pivotally mounted on the chassis and an arm pivotally connected at one end to the jib, a digging tool and a handling tool being permanently carried by the other end of the arm, the region of attachment of one tool to the arm being close to that of the other tool to the arm.
  • the present invention concerns improvements in digging and handling apparatus, particularly but not exclusively for public works.
  • Apparatus for carrying out this kind of work, which are provided with two sets of working equipment which are practically independent of each other.
  • such an apparatus generally has an auger suspended from the jib and, for handling the poles, lifting gear arranged either on a small jib pivoted on the main jib or on tele.-- scopic elements of the jib which has been designed telescopically for this one purpose.
  • handling and digging apparatus comprising a chassis, "a jib pivoted on the chassis, .,an arrn pivoted by one end on the jib, a digging tool permanently attached to the other end of the arm, and a handling tool permanently fixed to the other end of the arm close to the region of attachment of the digging tool thereto.
  • the arm is a conventional arm.
  • the two tools of the apparatus of the German application are mounted on a single support which, to enable each of the tools to be used, must be mounted rotatably relative to the jib on which it is mounted. Since the invention may be used with conventional working equipment of the type mentioned above, it is 2 then no longer necessary to resort to the costly rotary mounting of the support of the two tools.
  • the handling tool is attached to the arm in a movable manner.
  • the arrangement provided by the present invention permits fixed attachment of the handling tool to the arm, which'is also obviously the simplest mounting.
  • the handling tool clamp comprises a clevis swivellably mounted on a piece attached to the arm by a coupling rod.
  • a frame is swivellably mounted in the clevis and supports the bearings of the pivot axes of at least two pairs of bent levers, each of the levers of each of the pairs being connected by one' end of an hydraulic ram, while a jaw is pivoted on the other end, the jaws of each of the pairs of levers facing each other.
  • the jaws are provided on their working surfaces with a flexible covering.
  • means for releasably supporting the free end of the tool out of reach of the ground is provided vertically below the jib.
  • FIG. 1 shows an embodiment of apparatus in accordance with the invention, in one mode of operation
  • FIG. 2 is an enlarged front elevation view of the work handling tool with some parts removed for clarity;
  • FIG. 3 is a side elevation of the work handling tool of FIG. 2 as viewed in the direction of arrow F of FIG. 2.
  • the apparatus shown in FIG. 1 comprises the constituent elements of an hydraulic shovel, namely a chassis comprising a base 1 on which is pivvotally mounted a turret 2 and which is provided with rolling means 3 by means of which the apparatus rests on the grounnd 4.
  • a jib 5 is pivoted on the turret 2 while an hydraulic ram 6 is connected'between the jib 5 and turret 2.
  • An arm 7 is pivoted by one'of its ends 7a about an axis on the jib 5, its hydraulic control ram 9 being connected between this end 7a and the jib 5.
  • An auger 10, driven in known manner by an hydraulic motor 10a, is suspended from theend 7b of the arm 7 and is pivotable about axis 13.
  • the auger is shown held out of reach of the ground 4 by supporting means 1 1 arranged under the jib 5 and vertically below the latter.
  • This means 11 comprises, as shown, a cord 11a attached to a bracket 11b provided under the jib 5 and wound around part of the auger 10.
  • a handling tool 12 is also mounted at the end 7b of the arm 7.
  • This tool 12 is attached to the axis 13 of the auger and made fast with the arm 7 by a coupling rod 14.
  • the construction of this tool 12, which is in the working position in FIG. 1, will be better appreciated from the following FIGS. In FIG. 1 it is shown gripping pole 15 which is engaged in a hole 16 previously bored by the auger 10.
  • FIGS. 2 and 3 illustrate an embodiment of this handling tool 12.
  • the tool 12 comprises a clevis 17 mounted for swivel movement about a pivot shaft 17a on piece 18 normally pivoted at 19 on the axis 13 of the arm 7.
  • This piece 18 has an extension 18a to which is attached at 1819 one of the ends of the coupling rod 14.
  • the clevis 17 has two bearings 20a and 20b in which is swivellably mounted a body 21 supporting four bearings 22a, 22b, 22c and 22d. These bearings receive the pivot axes of four bent levers 23a to 23d.
  • These levers are pivoted in pairs and by one of their ends, in which an aperture is formed, at the ends of an hydraulic ram 24 controlled from the drivecab of the apparatus. Their other ends each carry a jaw 25a to 25:] which is pivotally mounted thereon.
  • levers 23a to 23d are arranged symmetrically about the ram 24 so that the jaws, in pairs, form gripping means. Moreover, the shape of the levers is such that the plane of movement of the jaws is infront of that in which the ram is arranged.
  • Such an appliance therefore enables a hole to be dug by means of the auger 10, which may be replaced by any other digging means, for example a cylindrical bucket, when the auger adopts a vertical position, as with known apparatus. It will be noticed that the arrangernent of the handling tool 12 in no way hampers boring of the hole 16. After the auger has been withdrawn from the ground, it is moved to and held in the position shown in FIG. 1 by means of the supporting means 11. The cord 110 can be wound around the auger 10 by rotation of the auger by means of the hydraulic motor l0a,which drives it.
  • the pole is then to be gripped by the tool 12.
  • the tool 12 By action on the jib 5 and the arm 7, and, where necessary, by manoeuvring the apparatus or the turrent towards the area in which the poles to be erected are stored, the tool 12 is placed in a position to grip a horizontally stored pole. In this position each of the pairs of jaws is arranged to span the selected pole. Pressurized fluid is then caused to enter the ram 24, Which causes the jaws to close on the pole.' The relative movement of the piston body. and the piston rods causes the ends of the levers 23, which are pivoted on them, to be pushed out. The levers rotate about their respective axes to cause the jaws 25 to move towards each other until they contact the pole which is thus gripped.
  • the gripping forces are advantageously evenly distributed between the pair of jaws 25a, 25b and the pair of jaws 25c, 25d regardless of the travel of each of them.
  • This is very advantageous 4 for gripping poles formed of sheet metal rolled in generally octagonal or pyramidal form and with a shallow slope.
  • the jaws may be covered 26 as illustrated on jaw 250 in FIG. 2 with a flexible covering.
  • the pole 15 is lifted to a vertical position to be introduced into the previously dug hole 16. Once this pole has been placed in position, the pressure is taken off the jaws to release the pole.
  • Handling and digging apparatus comprising a chassis, a jib pivoted on the chassis for pivotal movement about a horizontal axis, an arm pivoted by one end on the jib, a diggingtool pivotally attached to the other. end of the arm, and a handling tool permanently fixed to the same end of the arm as the digging tool closeto the region of attachment of the digging tool to the arm.
  • the handling tool comprises a gripping clamp which clamp includes a clevis mounted for swivel movement on a support piece connected to the arm by means of a coupling rod, a frame mounted for swivel movement on the clevis and supporting bearings of the pivot axes of at least two pairs of bent levers, wherein each of the levers I of each of the pairs is connected by one end to a hydraulic ram, and a jaw is pivotally mounted on the other end of said levers, the jaws of each of the pairs of levers facing each other.
