Definitions

  • the invention relates to a backhoe of the type specified in the preamble of claim 1, which is known from DE-PS 25 58 799.
  • a guide which extends transversely to the longitudinal axis of the superstructure, in front of the driver's cab, on which a slide can be moved transversely, on which the mounting bracket for the boom is pivotably mounted.
  • the guide In order to be able to excavate parallel to the longitudinal axis of the undercarriage with a usable lateral offset, for example in the extension of the respective lane, the guide protrudes beyond the superstructure on both sides. The guide is therefore of considerable length.
  • the invention has for its object to improve a backhoe of the type defined in such a way that can be dug with little lateral effort and large lateral offset, and that both when driving and when working either in the main grave position or at the longitudinal central axis of the Chassis laterally offset boom ensures good visibility for the driver.
  • the boom assembly mounted longitudinally on the lateral projection of the uppercarriage can be pivoted very easily in front of the driver's cab in a confined space, so that the digging material can be unloaded to the rear after the uppercarriage has been brought up and pivoted.
  • the comfortable transverse pivoting of the assembly also serves to concentrate the overall center of gravity on the area of the chassis in the driving position, whereby the driver has an unobstructed view due to the angled boom, the resulting free space and the driver's cab placed in the center of the superstructure with a free front.
  • the superstructure does not project laterally beyond the chassis either in the driving position with the boom assembly pivoted transversely into one end position or in a main grave position in which the second axis is located in the area between the lane and the vehicle longitudinal center line.
  • the driver has the possibility, as when working with conventional excavators, to adjust his boom in the longitudinal direction between the two lanes, this method of operation not requiring any tense attention. Since lateral boundary sections are provided on the superstructure, which in one position or another run approximately parallel to the respective lane, it is easy for the driver to orientate himself on these boundary sections or to bring them into alignment with the lane if he is off one pivots into the other position.
  • any number of different pivot positions of the uppercarriage are possible in order to dig with a greater or lesser lateral offset, the distance between the first and second pivot axes preferably being so dimensioned It may be that the second vertical axis is pivoted beyond the respective lane and can therefore be dug outside the lanes.
  • excavation work can be carried out from the main digging position or from the driving position with the boom set transversely to the longitudinal axis of the running gear, for example on trenches and embankments on roads and railways where the uppercarriage does not have the outer edge of the running gear may protrude and consequently any uppercarriage swings must be avoided.
  • the embankment there is often a requirement to work the embankment as far as the undercarriage or the rail, to pull it smooth along the slope slope or to carry out cleaning work there.
  • the section of the angled boom extending from the mounting bracket extends at least approximately at eye level to the driver in the approximately vertical end position, so that the adjoining angled section cannot obstruct the unobstructed view.
  • the projection of the uppercarriage, the attachment bracket and the boom assembly pivoted in front of the cabin can be located within one envelope circle, the radius of which is greater than that of the envelope around the counterweight.
  • the envelope circle is determined by the cross-pivoted boom assembly, which must be taken into account when the front of the superstructure has to be pivoted past an obstacle.
  • the second vertical axis has a distance from the front edge of the superstructure which corresponds to approximately half the usual digging bucket width.
  • the swivel mechanism of the attachment bracket consists of a hydraulic cylinder articulated in the depth of the superstructure, which is connected to the attachment bracket directly or via a coupling with an intermediate link.
  • the mounting of the mounting bracket on the side projection of the uppercarriage offers the possibility of conveniently accommodating an inexpensive hydraulic cylinder which, when directly linked, enables the boom to pivot sideways up to 170 °, which in many Cases are sufficient, while a translation by means of a coupling and between the handlebars can be used for even larger swivel angles.
  • the front edge of the uppercarriage is expediently partially formed by the front of the cabin, in front of which a protective grille is arranged.
  • a protective grille is arranged.
  • the backhoe according to the invention is further developed in that the width of the uppercarriage remains in the driving position substantially within the width of the chassis and in this position on the side next to the projection of the uppercarriage a front section and on the opposite side a rear section approximately parallel to the outer Suspension limitation run.
  • This design gives the uppercarriage the greatest possible width without protruding beyond the chassis contours in the driving position.
  • the swivel angle of the superstructure between the driving position and the main grave position is not fixed; in one embodiment, it is in the range of about 20 °.
  • the second vertical axis from the driving position of the superstructure comes into such a digging position in which it is located between the lane and the longitudinal center line of the chassis, so that the driver similarly in the case of a conventional backhoe, it sits somewhat to the side behind the boom.
  • the center of gravity of the counterweight expediently lies approximately in the plan view in the region of the longitudinal center line of the vehicle.
  • the counterweight provides the main proportion of the excavator's standing moment.
  • the side wall of the driver's cabin adjacent to the projection runs parallel to the outer wall of the uppercarriage which adjoins the projection at the rear. Furthermore, in the main grave position of the uppercarriage, the side wall of the cabin facing away from the projection can run approximately parallel to the undercarriage and to outer wall sections of the uppercarriage.
  • the rotatably mounted driver's seat has at least one detent position in which it runs parallel to one or the other side wall of the cabin.
  • a superstructure 2 which can be pivoted indefinitely about a first vertical axis 4, is mounted on a chassis 1, which is designed as a caterpillar drive, but can equally well consist of a wheel and tire drive.
  • the pivotability through 360 ° is generally achieved with the aid of a main rotary bearing 3 known per se, in that hydraulic feedthroughs and line connections are provided.
  • a part of the upper projection platform-forming side projection 24 is provided, on which a second vertical pivot axis 5 is arranged.
  • a mounting bracket 6 can be pivoted about the second vertical axis 5, to which, according to FIG. 2, an angled arm 8, 9, a dipper stick 10 and a digging spoon 11 are connected.
  • the mounting bracket 6 is held with upper and lower pivot pins in a mounting bracket pivot bearing 7, which extends forward from the platform of the superstructure and forms part of the projection 24 in the upper and lower tabs or attachments consists. From Fig. 1 it can be seen that the vertical distance of the second pivot axis 5 from the front edge of the superstructure or from the cabin front 22 corresponds approximately to half the width of a conventional digging spoon 11, so that the mounting bracket and boom can be pivoted substantially parallel in front of the cabin front .
  • section 8 of the boom adjoining the attachment brackets 6 in the drawn-in folded position has a length which extends over the eye level of the driver shown at position 28 in FIG. 2.
  • the dipper stick 10 and the filled digging bucket 11 there is a middle free space behind which the front 22 of the driver's cab 20 is arranged, so that the driver has an unobstructed view to the front and the floor in front of the undercarriage.
  • a preferred embodiment is a swivel mechanism of the attachment holder in FIG. 1, which indicates a hydraulic cylinder 15, which in principle could also be replaced by another swivel mechanism .
  • the cylinder 15 extends within the platform of the superstructure to the rear up to a pivot point 14.
  • the piston rod 16 is connected via a link 17 to a lateral connecting eye 19 on the mounting bracket 6 and is guided through a coupling 18 which is connected to a projection 24 mounted pin 21 is pivotable.
  • the rotary actuator shown enables a pivoting of the boom by at least 180 ° according to Fig.1, but this pivot angle is not binding. With the aid of this swivel angle range, the essential working positions shown as an example in FIGS. 4, 5 and 6 can be easily achieved, in addition to the driving position in FIG. 1.
  • the side section 40 of the uppercarriage adjoining the projection 24 extends parallel to the course or to the edge of the right chassis 13 (in the direction of travel).
  • the one rear sidewall section 48 extends parallel to the course of the left undercarriage 12 or, if it is a wheel undercarriage, parallel to the lane formed by the wheels.
  • the driver's cabin extends with a considerable section beyond the first vertical axis 4.
  • the cabin side wall 30 adjacent to the projection 24 runs parallel to the side wall section 40 of the uppercarriage. Behind and next to the cabin are not shown, conventional structures, z. B. the drive motor, storage tank, hydraulic units, etc.
  • the superstructure 2 is pivoted into the 'main grave position, in which the vertical pivot axis 5 of the cultivator 6 is approximately in the middle between the right chassis 13 and the vehicle longitudinal center line L is located, but could also be pivoted ver closer to the line L.
  • a rear 46 of the side wall of the superstructure runs parallel to the chassis 13 and on the opposite side a front side wall section 42 of the sidecar runs parallel to the chassis 12.
  • the center of gravity of the counterweight 38 is in this main grave position approximately in the area of the chassis longitudinal center line L.
  • the driver has the cabin side wall 32 available, which runs parallel to the sections 42, 46 of the uppercarriage.
  • the cabin rear wall 34 can have any shape.
  • the driver's seat 26 has an integrated excavator control indicated in the armrests. In order to maintain an unobstructed view to the front in the main positions of the uppercarriage according to FIGS.
  • the driver seat 26 can be pivoted about an axis 36, at least one detent position being provided in which the driver seat is parallel to the cabin side wall 30 or to the opposite side wall 32 runs.
  • a footboard 44 for entry into the cabin and onto the superstructure can be provided between the side wall section 42 and the adjacent cabin side wall 32.
  • the envelope circle H drawn in FIG. 1 by the counterweight 38 on the superstructure also includes the boom assembly folded in the driving position. In the case of smaller excavator types, the case may arise that the boom assembly protrudes beyond this enveloping circle H, so that in this case there is an enveloping circle determined by this assembly, the one has a relatively larger radius than the outer edge of the counterweight 38.
