Definitions

  • the present invention has for its object a mechanical srovel which can be used for excavation and loading work, but which is easily adaptable for use as a crane.
  • These devices generally comprise a jib pivoted about a horizontal axis on a turret rotating about a vertical axis and mounted on a platform or a driving chassis. On this jib is pivoted, about a horizontal axis, an arm which carries a tool at its extremity, for example an excavating bucket or a lifting hook.
  • a tool at its extremity for example an excavating bucket or a lifting hook.
  • the movements of the various parts are controlled by hydraulic or other jacks of the doubleaoting type, suitably arranged.
  • the present invention relates to improvements made in devices of this type, with a view to improving its reach and to improving its efiectiveness.
  • the jib-jack controlling the inclination of the jib is not directly articulated thereon, but through the intermediary of a lever device or rocking-lever, to which is further coupled an auxiliary jack pivoted at its opposite extremity on the jib, the pivotal or articulation axes of the various members being all horizontal.
  • the toolcarrier arm has two possible points of articulation for the arm-jack, preferably arranged symmetrically with respect to the axis of articulation of the latter on the jib, which is shaped so as to permit free movement of the arm jack in all cases.
  • the latter can thus be coupled to one or the other of these points, depending on the conditions of working.
  • the force which they generate is 1 larger in the direction of extension than in that of contraction, in consequence of the cross-sectional area occupied by the jack rod, which correspondingly reduces the free surface of the adjacent face of the piston as compared with the opposite face of the piston.
  • the coupling point of the arm-jack will thus be chosen so that its extension corresponds to the active stroke of the tool.
  • the active travel having the efiect of filling the bucket with material, is carried out in the direction moving away from the chassis, while on the other hand in the working known as reverse the bucket moves towards the chassis.
  • FIG. 1 is a diagrammatic view in elevation of a device according to the present invention, equipped in this example for working in reverse.
  • FIG. 2 is a plan view of the device of FIG. 1.
  • FIG. 3 shows the two positions of the jib corresponding to the extreme positions of the auxiliary jack when the jib-jack is extended.
  • FIG. 4 is a view similar to that previously referred to, but corresponding to the retracted position of the jibjack.
  • the device shown in the drawings is a mechanical shovel comprising an excavating bucket 1.
  • this bucket pivots at 2 at the extremity of a support 3, 23 which is articulated at 4 on a jib 5 pivoted at 6 on a turret 7 mounted on a driving chassis 8.
  • a rocking lever or lever device 9 is provided on the jib 5 and pivots about a shaft 10 n'gidly fixed on the jib.
  • a jack 11 known as the jibjack is pivoted on the one hand at a point 12 on the turret and on the other hand at a point 13 on the rocking lever, while a second jack 14, known as the auxiliary jack is articulated on the one hand at 15 on the jib 5 and on the other hand at a point 16 of the rocking-lever 9, situated beyond the pivot It) with respect to the first articulation point 13.
  • the support of the tool or bucket is equipped with a tail 17 having two points 18 and 19, symmetrical with respect to the articulation 4, for coupling to the rod 0 it jack 20 known as the arm-jack, the other extremity of which is pivoted at 21 on the jib.
  • the 'jib is of forked shape as can be seen from FIG. 2, and the jack 2.0 is arranged between the arms of the fork, which permits it to oscillate freely both upwards and downwards.
  • the tool support is adjustable in length in known manner, by sliding of the portion 3 in the form of a girder in a guide 22 provided in the part 23 rigidly fixed to the tail 17, and by pinning at a point such as 24.
  • a jack 25 known as the tool-jack is interposed between -a point 25 which can be taken on the sliding portion 3, and a point 27 on the reverse working bucket 1, the active travel of which corresponds to a movement approaching the chassis ofthe device.
  • This jack 25 enables the tool to be swung about its pivotal shaft 2.
  • the four jacks 11, 14, 2t) and 25 are double-acting hydraulic jacks. All the pivotal and articulation shafts 2, 4, 6, 10, 12, 13, 15, 16, 18, 19, 21, 26 and 27 are horizontal and parallel, only the the axis of rotation of the turret 7 is vertical.
  • FIG. 3 shows the jib in the top position corresponding to the extension of the jack 11 of the jib.
  • the arrangement when the auxiliary jack 14 is returned has been shown in full lines.
  • a lifting device comprising a supporting member, a jib member pivotally mounted on said supporting memher for inclination about a first horizontal axis, a rocking lever pivotally mounted-on the jib member about a second horizontal axis, a jib-jack for controlling the inclination of the jib member, said jib-jack having one end pivotally mounted on the .supporting member and an opposite end pivotally mounted on the rocking lever, and an auxiliary jack for varying the inclination of the jib member, said auxiliary jack having one end pivotallymounted on the 7 jib member and an opposite end pivotally mounted on the rocking lever.
  • a lifting device capable of operating as a mechanical shovel, comprising a turret mounted for horizontal rotation on a driving chassis, a jib member pivotally mounted on said turret for vertical inclination, a rocking lever pivotally mounted on the jib member, a jib-jack operating between respective pivotal connections thereof with the.
  • turret and rocking lever for controlling the inclination of the jib member, an auxiliary jack operating between respective pivoted connections thereof with the rocking lever and jib member for shifting said inclination, a tool-carrier arm pivotally mounted adjacent the extremity of the jib member and adapted to accommodate a bucket, and means for pivoting the tool-carrier arm relative to the jib member.
