Definitions

  • the invention relates to a mobile crane, in particular a mobile crane or crawler crane, with a main boom, a main boom extension and an adapter arranged between the main boom and the main boom extension with a first connection level and a second connection level, the adapter being designed to be movable in such a way that the first connection level relative to the second connection level is movable.
  • the European disclosure document EP 0 728 695 A1 discloses a mobile crane according to the preamble of claim 1 with a telescoping main boom and a telescoping main boom extension, which are connected to each other via an adapter.
  • the adapter is designed as a double rocker in order to move the main boom extension from a rest position, in which a longitudinal direction of the main boom runs parallel and next to a longitudinal direction of the main boom extension, into an operating position in which the longitudinal direction of the main boom extends in the longitudinal direction of the main boom extension.
  • the adapter has a main boom extension connection element and a main boom connection element, which run parallel to one another in the operating position and also in the rest position.
  • the German Offenlegungsschrift DE 10 2016 009 038 A1 discloses a comparable mobile crane with a telescoping main boom and a main boom extension.
  • the adapter is not designed to be rigid.
  • the adapter is only rigidly attached to the boom head on the one hand, but on the other hand a fastening frame that can be pivoted about a luffing axis is provided for fastening the main boom extension.
  • this fastening frame can be pivoted at the end opposite its luffing axis via an adjusting cylinder, whereby a luffing of the main boom extension can be achieved.
  • the adjustment cylinder is supported on the outside of the adapter as a mounting frame.
  • FIG. 101 898 728 A Another adapter for a mobile crane with a telescopic boom for luffing a main boom extension is also from the Chinese patent application CN 101 898 728 A known.
  • the adapter used there has, instead of the adjustment cylinder, a connecting rod that can be gradually changed in length using bolts.
  • main boom extension can also be attached to the main boom or the adapter in other fixed angular positions.
  • main boom extension can be swiveled in relation to the main boom or the adapter via two bolt connections.
  • This pivoting movement and the subsequent definition in the other angular position can be connected to tabs via hydraulic cylinders or other auxiliary drives.
  • the load transfer especially that of the transverse force, occurs only via the two bolt connections, which absorb the forces acting transversely to a system axis.
  • the torsional moments are also only distributed between two bolt connections because the hydraulic cylinders or shackles are connected in an articulated manner.
  • the object of the invention is to provide a mobile crane with an adapter between the main boom and the main boom extension, the load-bearing capacity of which is improved and the set-up is simplified.
  • the location of the pivot point "front” means that the pivot point or the rocking axis in the second connection level to the edge of the adapter, the dem Ground is facing or a counterweight of the mobile crane is facing away, that is offset in the direction of the main boom extension from the center.
  • the adapter is in the "front” position, the main boom extension can be set up easily.
  • main booms with a pivot point in the middle of the main boom head, i.e. at a distance from the lateral outer edge are also known.
  • the pivot points or the components of the pivot points are exposed to different loads depending on the angle of attack of the additional device.
  • the main boom can then be designed correspondingly lighter or achieve higher load capacities. Due to the limitation of axle loads for mobile cranes to 12 t for road operation, the weight and thus the weight of the main boom is an important criterion, especially for mobile cranes.
  • the adapter is fastened with its first connection level directly to a main boom head of the main boom and is fixed indirectly with its second connection level to a foot piece of the main boom extension.
  • additional intermediate pieces preferably as lattice mast elements, can be provided between the first connection level and the main boom head and/or the second connection level and the base piece of the main boom extension, which can also serve as an adapter and/or extension, for example.
  • an existing adapter in a different size can also be used in the sense of the invention between the main boom and the main boom extension.
  • the first connection level of the adapter is directly attached to a main boom head of the main boom is fastened and/or, preferably and, is fastened with its second connection level directly to a foot piece of the main boom extension. This advantageously optimizes power transmission and mobility in the area of the adapter, which is arranged near the head of the main boom and/or the base piece.
  • the adapter is designed as a double rocker.
  • the design as a double rocker allows in particular a defined mobility of the adapter and the adapter combines mobility with high static stability.
  • the adapter seen transversely and laterally to a longitudinal direction of the main boom, consists of a frame element, a rocker element, a coupling element and a crank element, which are connected circumferentially via first, second, third and fourth joint axes running parallel to one another and between A length-adjustable diagonal element is arranged on two diagonally opposite joint axes, with which the adapter is fixed.
  • first and fourth joint axis lie in the first connection level and the second and third joint axis lie in the second connection level.
  • the diagonal element can be designed in different ways.
  • the diagonal element is particularly preferably a piston-cylinder unit, which is in particular continuously adjustable.
  • the diagonal element is a sliding tab that can be fixed in different lengths.
  • a 0° position, a 20° position or a 40° position of the main boom extension relative to the main boom can preferably be set.
  • the adapter with a sliding lug as a diagonal can implement any other preset angle between the main boom and the main boom extension.
  • the diagonal element is a belt with a preselected length, which can be exchanged in particular for a change of position.
  • the preselected length of the chord corresponds to a 0° position, a 20° position or a 40° position of the main boom extension to the main boom.
  • a further alternative embodiment provides that the diagonal element can be adjusted, preferably steplessly, by means of a rack and pinion drive.
  • the frame element, the rocker element, the coupling element and the crank element are of different lengths.
  • the same length of the crank element and the link element is preferred if, for example, one wants to provide pure displacement but not a great deal of twisting of the main boom extension.
  • the rigid design of the movable adapter advantageously makes it possible to design the adapter so that it can be moved under load.
  • the positioning of the adjustable diagonal element in the diagonal of the adapter is particularly advantageous here, since when the diagonal element is actively moved under load, the main forces are conducted through the crank element and the oscillating element and the diagonal element, in particular the piston-cylinder unit, only transmits the forces transverse to the System axis must remove.
  • the figure 1 is a schematic and side view of a mobile crane 1, in particular a mobile crane that can be moved on public roads, which essentially consists of an undercarriage 2 and an uppercarriage 3.
  • the undercarriage 2 has a driver's cab 4 and four vehicle axles 5, each with two roadworthy, rubber-tyred wheels 6.
  • the undercarriage 2 can also be equipped with more or fewer than four vehicle axles 5 .
  • the undercarriage 2 also carries the superstructure 3 which, in relation to the undercarriage 2 , can be pivoted about an essentially vertically aligned axis of rotation D by means of a pivot bearing 7 .
  • the superstructure 3 and the undercarriage 2 can also be mounted rigidly one on top of the other.
  • a main boom 8 that can be luffed via a luffing cylinder (not shown) is mounted on the superstructure 3 and can be fully retracted for road travel and placed on the undercarriage 2 .
  • the main boom 8 is designed as a telescopic boom. It is of course possible that the main boom 8 can also be designed as a lattice mast carrier and/or the mobile crane 1 can be designed as a crawler crane.
  • the main boom 8 designed as a telescopic boom consists of a boom base box 10 and several telescopic sections 10a to 10d that can be extended and retracted and are arranged inside one another.
  • the innermost telescopic section 10d which is therefore the smallest in terms of its diameter, carries a main boom head 11 at its upper or outer end.
  • the adapter 12 is designed as a cuboid lattice mast element.
  • a so-called rigid main boom extension 16 is connected in a second connection level II via four additional bolts (not shown), which is aligned in the usual way only in one orientation to the main boom 8 via the adapter 12.

  • the main boom extension 16 is inclined at an angle b of approximately 20° to the main boom 8 .
  • the main boom 8 also includes a first guy support 18 which is arranged at the head of the boom base box 10 and points rearward at a right angle, over which a first guy rope 18a runs from the base of the base box 10 via the guy support 18 to the main boom head 11.
  • the main boom extension 16 is divided into a basic boom designed as a lattice mast, which is usually a framework tubular construction, and an adjoining tip 16b, which is designed as a box boom or framework tubular construction.
  • Such main boom extensions 16 are basically constructed as a modular system from individual main elements and can be put together depending on their length or load capacity. The individual main elements have transportable dimensions and in most cases are not carried along with the mobile crane 1 but are transported separately. If the axle loads of the mobile crane 1 and the size of the main boom extension 16 allow it, the main boom extension 16 can be carried along if necessary.
