Definitions

  • the invention relates to a device for mounting or dismounting a crane.
  • a crossbeam is attached to the tower pieces to be climbed.
  • the hanging of the traverse in the mounting hook of a tower piece located on the ground is done by an installer who climbs into the tower section to be climbed and leads the mounting hooks such that the tower to be climbed tower piece is securely received in the mounting hook.
  • the traverse received with the mounting hook is transferred to an installation position to a mounting trolley, which is mounted on a mounting tower.
  • the transfer of the tower section to be climbed to the mounting trolley by settling the crossbar in the mounting trolley. Since no backup is provided in the known mounting hook, there is a risk that in case of unintentional settling or tilting the traverse is pressed with the tower section to be climbed out of the mounting hook and the tower section crashes.
  • the crane In particular the tower crane, must be balanced with a balancing weight on a load hook, so that the center of gravity of the tower crane lies in a longitudinal axis of the tower crane. This is necessary to avoid tipping the crane and, in the worst case, overturning during climbing.
  • another tower section with a sling chain or a slippage is fastened to the load hook for this purpose.
  • For attaching the load hook must drive down again and a fitter hangs the balancing weight in the load hook.
  • the balance weight is raised to the height of the guide piece and moved into the balancing position. After the climbing process, the balance weight is lowered and unhooked. A lower bottle with the mounting hook is moved up again.
  • the GB 861 037 A shows a conventional device for mounting or dismounting a crane, in which the mast shot to be lifted can be conveyed by means of a compensation unit within the minimum boom span of the crane.
  • the object of the present invention is therefore to provide a device for mounting and / or dismantling a crane, which does not have at least the aforementioned disadvantages.
  • a device for mounting or dismounting a crane in particular a tower crane, has a coupling unit for coupling the device to a support of a tower section.
  • the coupling unit is designed and arranged such that it is in a locking position for avoiding a release of a coupling of the coupling unit with the support of the tower section or an unlocked position for coupling or decoupling the coupling unit with the carrier of the tower piece can be transferred.
  • a coupling unit with a locking position has the advantage that a release of the coupling of the carrier of the tower section with the coupling unit can be prevented safely and easily by unintentional settling or tilting of the carrier.
  • a release of the carrier of the coupling unit can only be done when the coupling unit is in an unlocked position. Foglich, the risk of a crash of a tower piece, for example, in a faulty placement on the mounting trolley, avoided.
  • a solution or decoupling should therefore only be possible if the coupling unit is transferred into an unlocked position.
  • unlocking each state of the coupling unit is understood in which at least a portion of the carrier and thus the tower section are added for coupling with the coupling unit or released for decoupling with the coupling unit.
  • the coupling unit may have a, in particular rotationally fixed, guide section for guiding at least part of the carrier, in particular a transverse pin of the carrier, of the tower section during a coupling operation.
  • the guide portion may have an inlet slope.
  • the coupling unit may have a rotatable hook. The hook and the guide portion may be connected to a mounting portion and the hook may be mounted on the mounting portion.
  • the guide section in particular the guide section with the inlet slope, it can be ensured that the coupling unit, in particular the guide section, at least part of the support contacted. Foglich no fitter is necessary, which leads the coupling unit on the ground accordingly.
  • the carrier in particular the transverse pin of the carrier, can penetrate into a receiving space of the coupling unit. After penetration of at least part of the carrier, the hook rotates back into the locking position, wherein the coupling unit is coupled to the carrier.
  • the coupling of the carrier with the coupling unit can be further simplified if a corresponding guide for the carrier, in particular the transverse bolt, is provided on the hook.
  • the hook may be coupled to a clamping unit, such as a spring device, in particular a gas spring.
  • the clamping unit can, in the event that the carrier and thus the tower piece, in particular in an installed position, are moved on the hook such a force that the hook is held in the locked position. Foglich is effectively prevented by the provision of the clamping unit releasing the coupling of the coupling unit with the support of the tower section.
  • the hook can be designed such that due to the self-weight force of the hook and / or the weight of the hook coupled to the carrier and thus the tower piece acts on the hook torque. This torque is directed to hold the hook in the locked position. As a result, a safe transport of the carrier and the tower pieces, for example, in the installed position, can be achieved in a simple manner.
  • the coupling unit may have a transmission means.
  • the transmission means may be formed boomerangförmig and rotatably disposed on the attachment portion of the coupling unit.
  • the axes of rotation of the hook and the transmission means can be coincident.
  • the transmission means with the clamping unit in particular a gas spring, in particular directly coupled.
  • the transmission means may be coupled to the hook.
  • the coupling of the transmission means with the hook can be done by a hook arranged on the coupling means, such as a pin.
  • a pivot point of the clamping unit is provided with the transmission means such that upon movement of the tower section in the installation position, the clamping unit exerts such force on the transmission means that a first leg is in direct contact with the coupling means of the hook.
  • the transmission means may comprise at one end, in particular at one end of a second leg, a connection means which can be coupled to an actuating rod.
  • the transmission means can be rotated.
  • the actuation with the actuating rod can take place when the door piece is located in the installation station and serves to transfer the coupling unit in the unlocked position.
  • the rotation of the transmission means takes place in such a way that the second leg is rotated in the direction of the coupling means of the hook.
  • the hook is rotated to an unlocked position. Prior to abutment of the second leg against the coupling means of the hook is not rotated.
  • the hook Upon actuation of the transmission means by means of the actuating rod, the hook can be turned so far that it is held in the unlocked position. This is because the transmission means and thus the point of articulation between the transmission means and the tensioning unit, in particular the spring means, are turned so far that acts on the transmission means and thus on the hook a torque which holds the hook and thus the coupling unit in the unlocked position.
  • an actuation of the transmission means only take place when no load acts on the hook. This may be the case when the carrier is placed without error, for example, on the mounting trolley. Thus, it can be determined by operating the transmission means in a simple manner, whether the carrier is placed correctly.
  • a device for mounting or dismounting a crane in particular a tower crane, has a coupling unit for coupling the device to a tower section.
  • the coupling unit has at least one balance weight for setting a center of gravity of the crane.
  • the balance weight can be in a compensation position, in particular when climbing the crane to be movable. This can be done for example by a horizontal and / or vertical movement of the balance weight.
  • the advantage in providing a balance weight in the coupling unit is that it is no longer necessary, as in the prior art, to lower the coupling unit for coupling with the balance weight to accommodate the ground level balance weight. Rather, the balance weight can be moved without lowering the coupling unit equal to a balancing position. The compensation is made by the integrated balance weight on the hook. This leads to a considerable time saving.
  • the hook can be coupled with the balance weight.
  • the attachment portion may be connected to the balance weight.
  • the device according to the invention can be used for mounting or dismounting a tower crane. Of course, other cranes can be mounted or dismounted with the device according to the invention.
