Definitions

  • the invention relates to a telescopic tower of a mobile or tower crane or the like. with a plurality, preferably two, of an outer tower piece telescopic, consisting of tower sections inner tower pieces which can be locked together in the extended state and in intermediate positions.
  • the object of the invention is therefore to provide a telescopic tower of the type mentioned, which can be quickly assembled and disassembled even in confined spaces and can also be combined into a road-appropriate transport unit.
  • this object is achieved in a telescopic tower of the generic type in that the inner tower piece in the lower region of two of its corner posts is provided on one side with a climbing device which consists of a retractable and extendable lower cross member and an upper cross member, each with both sides extendable and retractable lower climbing and upper support pawls are provided up to the cross bars of the outer tower section, and that the stroke of the lower crossmember corresponds at least to the distance between two cross bars of the tower sections.
  • the tower according to the invention can be manufactured as a telescopic unit up to a size which corresponds to the permissible transport volume of approximately 2.45 mx 2.45 mx 15.45 m, although the maximum permissible transport weight of approximately 23 t must not be exceeded.
  • the tower according to the invention can be combined into a compact transport unit in that the telescoping shots only have to be pushed together.
  • the simple assembly possibility is given in that the individual tower sections can be pushed out and pushed together simply and quickly by the climbing device, which is an integral part of the inner tower section. Since the climbing device is only arranged in the area of two corner posts on one side of the inner tower section, a large interior space remains which can still be used for the arrangement of the ladder system.
  • hydraulic cylinders are articulated in the hollow profiles of the two corner pillars, the piston rods of which carry the lower crossmember.
  • the piston rods are articulated below the guideway of the climbing pawls on the lower cross member, so that this is stabilized and tilting moments are avoided.
  • the lower crossmember can also be raised and lowered by other means, for example by using Spindles provided with spindle drives.
  • each of the telescopic tower sections against the lower one is secured by pawls which can be swung in and out and which engage in the abutment of the other tower section. These pawls ensure the axial position of the telescoped tower sections relative to one another in a simple and safe manner.
  • the pawls pivotally mounted on the upper ends of the corner spars of the tower sections and each pawl or the like above its storage via a lever. is articulated to a socket which is axially displaceably guided on a rod which is pivotally mounted about an axis parallel to the ratchet axis and that the rod passes through two compression springs, one of which between the socket and an axial abutment and the other between the Bush and a nut screwed onto the upper end of the rod is clamped.
  • This configuration simplifies the handling of the pawl, because it forms, as it were, an adjustable three-joint system with the rod, which can be set in the snap-in direction or snap-out direction.
  • the lower spring tends to pivot the pawl inwards. If the pawl is loaded by the spring in the direction of its pivoted-in position, it automatically snaps into its detent position when it is run over by the detent abutment provided with a ramp. Conversely, the upper spring can be pretensioned by unscrewing the nut so much that it overcomes the force of the lower spring, so that the pawl is pivoted into its pivoted-out position when it is relieved when the latched shot is raised, so that it is released from the abutment is released.
  • the upper spring is expediently designed to be harder than that lower one, so that it can overcome the force of the lower spring by appropriate pre-tensioning via the nut.
  • the corner pillars are provided with rollers approximately at a distance from the clamping length of the telescopic shots. These rollers simplify the guiding and telescoping of the inner tower pieces relative to each other and to the outer tower piece.
  • two pairs of rollers are arranged in each inner angular region of the tower pieces, which run on the outside of the corner spars consisting of box sections.
  • the clamping points consist of pin-like projections on the outside of the corner spars that are at right angles to one another, which engage in complementary receptacles on the inside of the other tower section, with two projections each that are offset by 90 ° there are clamping screws that clamp the projections in the abutments formed by the receptacles.
  • each tower section containing a telescopic tower section is articulated at its lower end and is guided in guide rails, which in turn are longitudinally displaceable in socket-like guide sections of the telescopic tower section, which are provided with an end stop for the extended guide pieces, are guided such that the upper ladder is guided in guide rails of the telescopic tower section provided with stops, that the back guards are articulated to the conductors in the form of parallelogram rods that the telescopic tower section with a driver and the parallelogram linkage of the upper ladder is provided with a pivotable driver, each of which runs on sliders or guide rollers of the parallelogram linkage and opens the back guards.
  • This configuration makes it possible to extend the ladders immediately with the telescoping of the inner tower sections and to open their back guards.
  • This configuration takes into account that the length of the ladder may only be about 6 m in each case and that each ladder is to be secured at its lower end by an intermediate or transfer platform.
  • the intermediate platforms for the ladder lying above are expediently provided such that they can be folded up and down in the area of the flaps that can be folded up and down.
  • the ladders and intermediate platforms of the inner inner tower section can already be installed because this is the last one to be pushed into its operating position.

In order to be able to accommodate the hydraulic lifting devices in the corner spars of the inner tower section, they have been widened. In the area of the climbing device accommodated at the lower widened end areas of the corner spars, two superimposed platforms 15, 16 are fixedly arranged on the inner tower section, which serve as an operating platform and to accommodate units for the climbing device. These platforms 15, 16 occupy at most half the cross-section of the square inner surface of the inner tower. The platforms 15, 16 are connected to one another by a permanently installed ladder 17.

  • the abutments 5 arranged on the central inner tower piece and on the inner inner tower piece on the corner spars have angular recesses into which the correspondingly shaped free ends of the pawls 6 snap.
  • the upper surfaces of the locking steps are slightly sloping towards the outside to ensure a good locking engagement.
  • a rod 28 is pivotally mounted about an axis 26 parallel to the axis 23 on the upper edge reinforcement 27 of the upper end of the outer tower piece, on which a bushing 29 is slidably guided in the axial direction.
  • the pawl 6 is provided on both sides with welded tabs 30 which are articulated to the socket 29 at their free ends via bolts, not shown.
  • the rod 28 passes through two coiled compression springs 31, 32.
  • the lower compression spring 21 is clamped between an articulated bearing bracket 33 of the rod 28 and the lower side of the bushing 29, while the upper compression spring 32 is clamped between the upper end of the bushing 29 and a nut 35 screwed onto an end thread of the rod 28.
