Definitions
- the invention relates to a mobile crane according to the preamble of the claim 1.
- the arrangement of supply lines in the telescopic boom is not only expensive, but this also requires larger spaces between the individual shots or telescopic shots, so that the telescopic Shots essentially do not encompass the entire cross-section of these Can cover shots, but with correspondingly smaller cross sections must be executed.
- a telescopic boom for a mobile crane is known from the shots each enclosing an inner telescopic shot are provided at their outer ends with locking bolts which are in bores the bordered shots can intervene and via spring-loaded rods and Lever mechanisms can be disengaged and engaged. Unlocking takes place via the linkage and the lever mechanisms by a hydraulic cylinder.
- a crane is known in which the individual shots are one have a rectangular cross-section with longitudinal straps running in the corners, which are mutually spaced by transverse struts are connected.
- the cylinder extending and retracting these grid-shaped shots is bordered by a cage consisting of a tin box, with cross plates is provided, on which four cylinders opposite each other are supported by hydraulic piston-cylinder units, two of which are each the movement of the locking bolts and two each extending and retracting the driving pin.
- the object of the invention is therefore a compact telescopic boom to create a mobile crane with an extension device for this.
- the individual telescopic are Shots only at their inner ends, each with a radially movable, spring-loaded locking bolts, all with a common, piston-cylinder unit arranged on the extension and retraction cylinder can be actuated so that each shot associated bolt cylinder or actuating devices for the locking bolts are omitted.
- the Coupling pieces of all locking bolts from circular Washers exist, which have shafts with the locking bolt are connected and are in a common axial plane, that the mating coupling piece of the radial piston-cylinder unit a trough-shaped in the axial direction Section with a U-shaped profile is at the free ends his thigh is provided with webs pointing inwards, that the webs between them delimit a gap, the width of which corresponds to the diameter of the shaft, and that the legs have an inner distance from each other, the diameter corresponds to the disks.
- the radial piston-cylinder unit for pulling in the locking bolt can only be operated when the driver device with the recordings of the out or in-telescopic shot is coupled. This ensures that the individual telescopic shots are never in one unlocked state.
- the receptacles expediently consist of bores or bushings for retractable locking bolts, the driver device from a block with opposing cylinders for those formed by their pistons or piston rods retractable and extendable bolt is formed.
- the Bores consist of elongated holes running in the axial direction and the locking bolts are circumferential at their outer ends Show bundles or beads. Because the locking bolt itself support on the ends of the elongated holes, they overlap the elongated holes with their cuffs or beads, so that an additional Protection against unintentional, automatic loosening of the Bolzens is created.
- the means positioning the cylinder expediently exist reflective light barriers attached to this Scan marks attached to the shots.
- the shots expediently consist of profiles, the top of which are formed from U-shaped pieces, the legs with welded to the edges of lower, semicircular or semi-oval shells are.
- profiles of the individual shots of the telescopic boom are known from EP 0 499 208 A2.
- the telescopic crane according to the invention is characterized by a very simple and safe design. All limit switches as well electrical and hydraulic parts are on the telescopic cylinder. For locking the individual telescopic shots no special energy supply is necessary. This eliminates all energy supply lines, so-called “energy supply chains", Control boxes and other related equipment.
- a telescopic boom 1 with a outer shot 2 can be seen from the telescoped telescopic shots 3, 4, 5 and 6 are telescopic.
- a single-stage piston-cylinder unit 7 is provided for telescoping and retracting the individual telescopic sections 3 to 6 .
- the outer shot 2 is at its inner end through the boom link 8 closed.
- This boom link 8 has two forked bearing legs 9, 10 with aligned bearing bores 11 on the outer shot 2 in the usual way pivotable on a swivel axis in the superstructure of a crane vehicle is stored.
- On the outer shot 2 is also still the piston rod of the rocker cylinder in a manner not shown articulated.
- the piston rod 12 of the single-stage, hydraulic piston-cylinder unit 7 has a head piece 13 at its inner end provided, via which they are articulated on the boom articulation piece 8 is stored.
- the cylinder 18 of the piston-cylinder unit 7 is at the outlet end the piston rod 12 is provided with a collar 19 which cylinder bores on opposite sides in the median longitudinal plane has locking bolts 20 as pistons, 21 are performed.
- the telescopic sections 3 to 6 wear on their inner ends welded, frame-shaped end pieces 22 to 25, on opposite sides symmetrical to the luffing plane of the Telescopic boom 1 are provided with cup-shaped bushings 26, form the receptacles for the locking bolts 20, 21.
- FIGS. 1 to 3 retracted state of the telescopes 3 to 6 have the center lines of the holes in the receptacles equal distances from each other. So far the corresponds Telescopic boom the telescopic boom according to EP 0 476 225 A2.
- the telescopic telescopes are centered in their upper walls Shots 3 to 6 spring-loaded locking bolts at their ends 30 to 33.
- These locking bolts are in holes the top walls of the telescopic shots can be moved longitudinally guided and loaded in the direction of extension by compression springs 34, the bundles formed on the one hand on stops 35 and on the other hand, on step-like recesses of covers 36 support that a housing-like cage of the locking bolt conclude.
- the locking bolts are supported with the collars 35 on the inner edges of the holes in the top walls of the telescopic shots.
- the locking bolts 30 to 33 carry shafts 37 in the middle at their inner ends their inner ends are provided with circular disks 38.
- the disks 38 are located, as can be seen from FIG. 3, on a common level.
- the shots 2 to 5 have at their inner and outer ends Bores 39 in which the locking bolts 30 to 33 for Interlock.
- the locking bolts are on theirs the locking holes 39 penetrating with free ends circumferential, annular beads 40 provided for securing serve against accidental loosening.
- the outer locking holes 39 as can be seen from FIG. 6, as in Elongated holes formed in the axial direction.
- the locking bolts support themselves in the locked position of the extended Shots on the inner ends of the elongated holes 39, so that the annular beads 40 shown in FIG. 6 Way overlap the lower edge of the locking hole 39.
- the telescopic cylinder 18 is in the region of its exit collar the piston rod 12 perpendicular to the horizontal Level in which the cylinder bores with the locking bolts 20, 21 are located on its top with another Piston-cylinder unit 50 provided, the piston 51 on his provided upper free end with a groove-shaped recess 52 which is in the axial direction.
- This gutter-shaped Recess is U-shaped in cross-section, with the upper Ends of the leg webs 53 are attached between them limit a gap through which the shaft 37 of the locking bolt 30 to 33 can pass through.
- the profile the telescopic sections correspond to those in EP 0 499 208 A2 described profile shapes.
