Definitions
- the invention relates to a mobile work machine with a multi-axle vehicle substructure carrying the work machine and at least one support arm, preferably telescopic, which can be supported at its free end with an extendable foot part at the free end and which has an articulation point between an articulation-side articulation point and a articulation arm side extending hydraulic working cylinder about a pivot axis parallel to the vertical axis of the vehicle from a first end position, preferably pivoted against a longitudinal side of the vehicle underframe, into a second end position, which is preferably laterally extended on the vehicle underframe.
- Mobile work machines of this type are, for example, concrete pumps or mobile cranes. In their swung-out end position, which is supported on the floor, the support booms ensure a secure stand when extending and swiveling a concrete placing boom or a crane boom.
- the invention is based on the object of improving the known working machine in such a way that the supporting width can be changed with simple means via the supporting boom.
- the solution according to the invention is based on the idea of adjusting the articulation point on the substructure when the working cylinder is articulated by means of a drive element relative to the vehicle base and locking it in at least two predetermined adjustment positions on the vehicle base.
- a separate drive motor or drive cylinder as the drive element. It is of particular advantage, however, if the existing working cylinder is used for this purpose, the foot part being supported on the floor side in an intermediate position of the support arm and the working cylinder being actuated in this intermediate position while adjusting the unlocked articulation point on the substructure side.
- the adjusting mechanism has a thrust member which is guided in a thrust guide of the substructure and carries the articulation point of the working cylinder on the substructure side.
- the adjusting mechanism has a crank member, which is mounted on a pivot bearing of the substructure and carries the articulation point of the working cylinder on the substructure side.
- the predetermined adjustment positions are expediently defined by end stops for the thrust member or crank member which are fixed to the base.
- a mechanism for locking the thrust or crank member in the predetermined adjustment positions on the vehicle underbody is also provided.
- the locking mechanism can have a locking bolt that can be inserted into overlapping openings in the vehicle substructure and the thrust or crank member.
- a motorized drive element or a drive element designed as a drive cylinder can be provided for controlling the locking mechanism.
- the support boom is advantageously pivoted from one of the end positions into an intermediate position under the action of the working cylinder with the foot part lifted off the floor.
- the intermediate position the foot part is supported on the floor.
- the locking of the articulation point on the substructure is then released and the working cylinder is adjusted to a predetermined value by adjusting the articulation point Adjusted position actuated.
- the foot part raised from the ground and the support strut of the lung insectstel ⁇ from under the influence of the work cylinder into the other end pivoted.
- Figure 1 is a view of a truck-mounted concrete pump parked on the roadside with outrigger arms supported narrowly on the road side.
- FIG. 2 shows a plan view of the vehicle substructure of the truck-mounted concrete pump according to FIG. 1;
- Fig. 3 is an enlarged section of the vehicle with built- ⁇ trained in an intermediate position kept ⁇ bank position the support boom and as a push member for adjusting the articulation of the un ⁇ terbau simplee Häzylin ⁇ DERS;
- FIG. 4 shows an illustration corresponding to FIG. 3 with an adjusting mechanism designed as a crank rocker for the articulation point on the substructure.
- the mobile concrete pump shown in Fig. 1 consists essentially of a multi-axle vehicle substructure 10, a concrete placing boom 14 mounted on a mast bracket 12 near a front axle and rotatable about a vertical axis, and a support structure which has a support frame 16 underneath the base and two front and rear support brackets 22, 24 each pivotable on the support frame 16 about right axes 18, 20 .
- the support arms 22, 24 can be supported on the floor 28 with a foot part 26 which can be extended downward.
- the foot parts 26 of the front outrigger arms 22 are located on a telescopically extendable outrigger part 30.
- the support arms 22, 24 are shown in an end position B, which is closer to the chassis.
- the rear outrigger arms 24 need only be pivoted by a slightly smaller angular dimension than in FIG the end position A.
- the pivoting kinematics are changed by adjusting the articulation point on the substructure 36 required.
- the articulation point is adjusted with the aid of an adjusting mechanism which, in the case of FIGS. 2 and 3, can be displaced in a push guide 42 which is under the most underneath and which supports the articulation point 36 and which in the case of FIG. 4 can be pivoted about an axis of rotation 46 fixed under the underside , the linkage 36 supporting crank member 48 is formed.
- the thrust member 44 and the crank member 48 can be locked with the aid of a locking bolt 50 in the predetermined adjustment positions formed by openings 52 on the substructure.
- the front outrigger arms 22 When opening into the end position B, the front outrigger arms 22 are first swung out from the swung-in end position D into an intermediate position C.
- the articulation point 36 is in its normal adjustment position close to the substructure, from which an adjustment of the front support arm 22 to the normal end position A would also be possible.
- the piston rod 34 of the drive cylinder 32 In the intermediate position C, the piston rod 34 of the drive cylinder 32 is aligned with the thrust guide 42. If the foot part 26 is lowered to the floor 28 in the intermediate position C, the thrust member 44 can be moved into its outer adjustment position when the locking bolt 50 is pulled out Moved 52 and then there approximately bolt with the Arretie ⁇ be secured 50th In this case, the steering ⁇ reaches point 36 in the in Fig.
- the boom part 30 of the support boom 22 does not need to be telescoped.
- the permissible working area of the concrete placing boom 14 is on the broadly supported side and covers an angular range of 180 'there.
- the actuation of the adjustment mechanism shown in FIG. 4, designed as a rocker arm, is carried out in a manner similar to the adjustment of the linear adjustment mechanism shown in FIGS. 2 and 3, also via an intermediate position C.
- the only difference is that the crank member 48 is pivoted about the axis of rotation 46 with the locking bolt 50 released with the aid of the working cylinder 32 and is not moved.
- the articulation point 36 on the substructure is positioned from its substructure-near to its substructure-adjusted position so that the kinematic Tik the issuing process changes in the manner described above.
- the invention relates to a mobile machine, in particular a truck-mounted concrete pump or a mobile crane.
- the mobile work machine has a vehicle substructure 10 and at least one, preferably telescopic support boom 22 which can be supported on the free end with an extendable foot part 26 at its free end and which has a hydraulic working cylinder 32 which extends between an articulation point 36 on the substructure side and a articulation point 40 on the support boom side can be pivoted about a pivot axis 18 parallel to the vertical axis of the vehicle from a first end position D pivoted against a longitudinal side of the vehicle underbody 10 into a second end position A, B which is laterally shown on the vehicle underbody.
- the articulation point 36 on the substructure when the working cylinder 32 is articulated, can be adjusted relative to the vehicle substructure 10 by a drive element and specified in at least two Adjustment positions on the vehicle substructure 10 can be locked.
