Definitions

  • the invention relates to a device for hydraulic crawler and mobile excavators or similar carrier vehicles.
  • It has a directional link which is articulated on the arm and can be rotated in a force-locking manner, on which an upper arm and an upper arm rod which is parallel and of the same length and which is parallel to the upper arm and which jointly guide a parallel link, on which a lower arm which carries the tool, on the same axis with the upper arm and is mounted on its own plane, with a drive and synchronous device forcing equal but opposite angular deflections of the upper and lower arm, which have approximately the same length.
  • the object of the invention is to combine this known working arm with a likewise known universal joint boom, the boom head of which can be pivoted out of the plane of movement of the basic boom, and to match the two parts to one another in order to enable a broad application.
  • Different types of tools should be able to be guided on the known straight, automatically repeating and curvable forced path with variable throat and height in radial to tangential direction, based on the axis of rotation of the excavator superstructure. Any increased stress on the slewing gear and any slipping of the hydraulic excavator should be reduced by suitable means.
  • the familiar exchange of working stroke and fast return is to be simplified.
  • Claim 2 characterizes a spoon which can be easily rotated.
  • Claim 3 the use of wide leveling and trenching buckets is possible.
  • claim 4 when the excavator bucket is suddenly emptied, a counterweight movably mounted on the boom head can be accelerated from the rest position.
  • the claims 5 and 6 characterize additional parts for increased radius and altitude. For tangential digging work, a penetration knife can be attached to the basic boom.
  • the spoon can be turned. For example, Falling and rising embankments can be worked in both directions with full tear strength. A support position that goes beyond the cut position is made possible by the spoon cylinder directly or via an intermediate lever with a handlebar.
  • the bucket can dig in the direction of the pivot of the excavator with the boom head slightly pivoted so that the slewing gear is not stressed (Fig. 3).
  • the boom head is swiveled, whereby the bucket is guided to the side of the excavator or past the uppercarriage in a curved, forced way to the rear.
  • the bucket or a dozer blade or fang can also excavate, level, profile or tear open outside the lane and across the excavator, i.e. tangentially. (Fig 4). Narrow trenches, particularly those with shoring, can be excavated transversely in front of the superstructure, with the excavator running parallel to the trench.
  • the boom can be equipped with a plunge knife to prevent the entire excavator from turning away and high loads on the uppercarriage slewing gear during cross excavation.
  • the penetration knife can also serve as a support plate in order to increase stability, especially when the directional link is extended.
  • the basic boom 1 is articulated on the superstructure 2 of a hydraulic excavator and can be rotated about a horizontal axis by means of boom cylinders 3 and 3 'articulated on the excavator.
  • the boom head 4 can be pivoted about a pivot axis 6 lying in the plane of movement of the basic boom 1 by the pivot cylinder 5 articulated on the basic boom 1, the piston rod of which is pinned on the boom head 4 by means of locking pins 31 or 32.
  • a directional joint 7 is arranged at right angles to the pivot axis 6, to which the directional link 8 is articulated, which can be rotated in a force-locking manner by the directional cylinder 9 which is also articulated on the boom head 4.
  • the directional arm 8 rotates the direction of movement of a tool guided by the working arm about the directional joint 7.
  • the upper arm 10 can be articulated on a special upper arm joint 28 or in a known manner together with the boom head 4 on the directional joint 7.
  • Upper arm 10 and forearm 11 are each driven by an upper 12 and forearm cylinder 13, the cylinders being articulated on the arms 10 and 11 and the piston rods on the two-arm parallel link 14, which is guided through the upper arm rod 17 parallel to the directional link 8.
  • the two piston rods are articulated on the opposite arm of the parallel link 14, the cylinders 12 and 13 remaining in their plane.
  • the power stroke takes place away from the hydraulic excavator, in FIGS. 2 and 3 towards the hydraulic excavator.
  • the synchronization of the two cylinders 12 and 13 is regulated via the oil quantities supplied and discharged.
  • a spoon link 29 can be articulated on the forearm joint 19 and is guided through the forearm rod 18 parallel to the parallel link 14.
  • the spoon 16 is articulated on the spoon joint 34 of the spoon link 29.
  • the spoon 16 is removed, turned over and articulated again to the spoon link 29 and the piston rod of the spoon cylinder 30 pivoted through the central position.
  • the required spoon rotation angle is smaller than is customary in excavators and can also be achieved without the known transmission lever with direct linkage of the piston rod of the spoon cylinder 30 to the spoon 16.
  • the boom head 4 is pivoted so much to the right that the bucket 16 digs in the direction of the superstructure pivot 15 despite the asymmetrical arrangement. As shown in dash-dotted lines in Fig. 3, the bucket can also dig tangentially to the excavator next to the lane.
  • the bucket 16 By pivoting the boom head 4 to the left during the lifting movement, the bucket 16 is guided into the emptying position indicated by dash-dotted lines. This pivoting begins before the bucket 16 has reached the middle of the forced path.
  • the emptying distance can be increased by swiveling the superstructure 2 to the right.
  • a guide 21 for a counterweight 22 and a respective push cylinder 23, 23 ' can be arranged on the boom head 4', which are connected by lines 24 and 25 to the annular spaces 20, 20 '.
  • the pressure cylinders 23, 23 ' are supplied with pressure oil, as a result of which their piston rods lift the counterweight 22 vigorously.
  • the counter mass 22 after relieving the annular spaces 20, 20 ', e.g. returned to the starting position by its own weight and drives out the oil.
  • the separate connecting lines 24 and 25 ensure the synchronization of the arms during the reversal of movement with different loads on the cylinders 12 and 13.
  • the guide 21 is pivoted to the opposite side, as indicated by dash-dotted lines.
  • the directional link 8 'can consist of two parts and enables a large adjustment angle from vertically downwards to vertically upwards by means of the detachable articulation part 27, to which the directional cylinder 9 is articulated, around spoons, grippers, load hooks, ramming and pulling tools and the like to be able to move in suitable directions.
  • an extension 26 is attached to the directional link 8 'to increase the range.
  • the working arm guides a wide leveling or digging bucket 35, pushing upwards on the rising slope and pulling horizontally and on the falling slope.
  • the inclination of the surface generated and its distance from the excavator and can be changed by the interaction of the directional cylinder 9 and boom cylinder 3, 3 '. Swiveling the boom head 4 'in opposite directions and rotating the superstructure 2 also causes a change in radius.
  • Unilateral cutting of the spoon cutting edge can be eliminated or achieved, either by rotating the upper carriage 2 if the removal surface is not perpendicular to the upper carriage pivot 15, or by pivoting the boom head 4 'if the removal surface is not perpendicular to the pivot axis 6.
  • the bucket edge can be tilted sharply by pivoting the boom head 4 'when the movement path of the bucket 35 is approximately parallel to the pivot axis 6, which can sometimes save a pivoting bucket.
  • the device guides a tool of various types, for example a drilling device 33.
  • a drilling device 33 In the deep position shown in dash-dot lines, the drilling device 33 is guided vertically to far below the schedule.
  • the movement path of the drilling device 33 can be brought in any direction from forward inclination to strong inclination backwards and the radius can be changed.
  • the upper arm rod 17 is released from the directional link 8 'and the auxiliary lever 38 is permanently attached to the latter.
  • the directional arm 8 ' is turned upwards without rotating the upper arm 10.
  • the upper arm rod 17 is articulated on the articulation eye 39 of the auxiliary lever 38.
  • the arms 10, 12 now swing forward and are not hindered by the boom in the case of the side inclination shown in FIG.
  • the drilling device 33 can be tilted on all sides in a large area.
  • the boom is shown with the boom head 4 'pivoted in the transverse position.
  • a plunge knife 37 with a handle 36 which is fixed in the puncture position, is arranged on the basic boom 1 '.
  • the penetration knife 37 is pressed into the ground when the basic boom 1 'is lowered (see FIG. 4) and largely absorbs the digging forces of the bucket 16 digging in front of the superstructure 2 and transversely to the boom 1'.
