Definitions

  • the invention relates to a crane, in particular an offshore crane, with a slewing gear and a hydraulic slewing gear drive, wherein the slewing gear is held in its position by a retaining moment applied by the hydraulic slewing gear drive.
  • Crane structures are regularly designed for a certain maximum permissible load torque. Exceeding this allowable load torque can lead to a significant risk to the boom system and other crane components and cause permanent damage to the entire crane design. Therefore, cranes usually have an overload protection that causes a shutdown of the crane operation when exceeding the allowable forces on the crane construction.
  • overload protection only takes into account the vertical movement of the load during crane operation.
  • the load on a ship is moved by the wave motion of the sea possibly in addition to the vertical movement in the horizontal direction, whereby the ship or the load drifts sideways to the crane.
  • a lateral movement can cause a dangerous load torque on the cranes used construction, in particular on the slewing and on the boom.
  • a crane according to the preamble of claim 1 is made US Pat. No. 3,690,387 known. Object of the present invention is therefore to develop an overload protection for a crane, taking into account the above problem.
  • a crane in particular an offshore crane, with a slewing gear and a hydraulic slewing gear drive according to the features of claim 1.
  • the slewing drive brings in a manner known per se, a torque on the crane turning to effect a rotational movement of the crane about a vertically disposed axis of rotation.
  • a holding torque is introduced by the hydraulic slew drive on the slew to hold this in the desired position.
  • the basic idea of the invention is now to regulate the applied holding torque in order to prevent exceeding the maximum permissible load torque on the slewing gear due to the load movement.
  • the determination of the maximum permissible load torque occurs as a function of the projection and / or the position of the crane hook.
  • the crane provides an overload safety device which has at least one detection means for detecting the projection and / or position of the crane hook and at least one pressure relief valve.
  • the overload protection is designed so that at least one pressure relief valve applied to the hydraulic slewing drive system pressure and consequently the resulting holding torque on the slewing drive in response to the projection and / or the position of the crane hook is adjustable.
  • the maximum moment occurring on the slewing can be limited by the rotation, which can prevent potential damage to the boom.
  • a diagonal train of an attached load leads to a rotational movement of the slewing gear, if the maximum torque, that is, the holding torque determined by the crane turning drive, is exceeded.
  • the adjustable holding torque on the slewing gear is reduced as a function of the projection and / or position of the hook.
  • the pressure in the system pressure line can be reduced by at least partially opening the pressure relief valve (s).
  • the one or more pressure relief valves are arranged so as to switch in the open state, a short circuit between high and low pressure line to the slew drive. The degree of opening of the pressure relief valve (s) then determines the flow rate within the short circuit and thus the degree of pressure reduction in the high pressure circuit.
  • the overload protection comprises at least one pressure relief valve, in particular a proportionally controllable pressure relief valve.
  • the output pressure of the pressure relief valve is connected as a control pressure on at least one or preferably all pressure relief valves. Accordingly, the respective degree of opening of the pressure relief valve or valves can be compensated via the pressure limiting valve.
  • the pressure relief valve is made adjustable and the overload protection or the control unit of the overload protection regulates the output pressure of the pressure relief valve and consequently the applied control pressure to at least one pressure relief valve depending on the detected projection and / or the position of the crane hook.
  • the system pressure or the resulting holding torque on the slewing drive can therefore be regulated via the controllable pressure limiting valve as a function of the detected projection and / or the position of the crane hook.
  • control line is connected at least one or all pressure relief valves via at least one check valve with the system pressure line of the rotary drive.
  • control line is connected via at least one check valve with the supply of the system pressure line to the hydraulic slew drive and via at least one check valve with the return of the system pressure line.
  • the hydraulic slewing drive preferably comprises at least one hydraulic motor for carrying out a rotary movement of the slew drive.
  • the required holding force on the slewing drive is generated by the drive torque of the hydraulic motor.
  • the present invention therefore provides for a corresponding control of the hydraulic motor over the present system pressure in order to regulate the applied holding torque as a function of the projection and / or position of the hook.
  • a hydraulic parking brake may be provided which applies a corresponding holding torque on the slewing drive in addition to the hydraulic motor.
  • the overload protection according to the invention adopts a corresponding regulation of the control pressure in order to apply the desired holding torque via the slewing gear drive.
  • a user-defined maximum limit holding torque flows into the activation of at least one pressure relief valve.
  • a limit is particularly preferably taken into account in the control of the proportional pressure limiting valve.
  • the pressure relief valve can basically be designed and arranged differently. It can be provided that the discharge side of the pressure relief valve is connected to a tank of the system.
  • the one or more pressure relief valves may themselves have different configurations.
  • at least one pressure relief valve may be formed as a valve cartridge or so-called cartridge valve.
  • the overload protection of the crane in development of the invention may include a switching valve that activates the overload protection function only in the energized state. For example, in the non-energized state, the pressure relief valve is locked by the pressure line between the pressure relief and pressure relief valve is locked.
  • the switching valve may be associated with a position sensing device, in particular a switching position monitoring, which monitors the switching position of the switching valve and thus enables error detection.
  • the complete overload protection of the crane is not limited to the regulation of the holding torque on the slewing gear.
  • the overload protection according to the invention can basically measure and monitor further moments and forces on the crane system and, if appropriate, control the individual crane drives appropriately, such as, for example, controlled actuation of the hoist drive for omitting the hoist rope in the event of overload.
  • Drawn crane 10 is rotatably supported by means of a slewing gear 30 about a vertical axis A on an offshore platform 20. It has a cantilevered about a horizontal rocking axis boom 40, on the top of a hoist rope 50 runs, which serves to receive the mounted on the ship 90 load 100.
  • the hoist rope 50 can be lowered and overtaken by means of a hoist winch.
  • the illustrated crane 10 is equipped with an overload protection, which should avoid a threat to the boom 40 of the crane 10 and to protect the entire crane structure from damage when changing the load torque.
  • the overload protection comprises a control device which is connected to a load hook position detection device, which on the one hand detects the respective load acting on the crane 10 and on the other hand the respective position of the load hook or the attached load 100.
  • the overload protection comprises a Ausladungssensor, the unloading of the crane 10, d. H. detected the horizontal distance of the running of the top of the boom 40 hoist rope 50 from the vertical axis of rotation A of the crane 10 and the control unit of the overload protection notifies.
  • the torque on the slewing gear 30 should be limited in order to prevent potential damage to the boom 40.
  • the vessel 90 diagonal pull of the hoisting rope 50 lead to an inadmissible load torque on the crane structure, in particular on the slewing gear 30.
  • a relief of the crane structure is now to be achieved according to the invention by a situation-dependent adjustment of the applied torque applied by the slewing drive to grant a rotational movement of the crane 10 about the vertical axis of rotation A in case of overload.
  • the maximum permissible torque on the slewing gear 30 is dependent on the design or the position of the crane hook on the hoist rope 50.
  • FIG. 2 shows a schematic representation of the circuit for driving the slewing 30.
  • the hydraulic circuit comprises the hydraulic motor 110, which is acted upon by the supply and return of the system pressure lines 120, 120 'with the desired pressure to to cause a corresponding rotational movement of the crane 10 about the axis of rotation A.
  • the flow direction determines the direction of rotation of the hydraulic motor 110.
  • a definable holding torque is set via the system pressure lines 120, 120 ', with which the hydraulic motor 110 keeps the slewing gear 30 in position during crane work.
  • the pressure level in the system pressure lines 120, 120 ' is usually a in the FIG. 2 not shown hydraulic pump determined.
  • the flow side 120 of the control pressure line of the hydraulic motor 110 is connected to a pressure relief valve 130, which in the illustrated embodiment is a so-called cartridge pressure valve and the input side is connected to the Spese für für 120 'of the hydraulic motor 110.
  • a pressure relief valve 130 which is connected on the input side to the system pressure line 120 and on the output side to the system pressure line 120' of the hydraulic motor 110.
  • the opening of the pressure relief valves 130, 130 ' is controlled hydraulically via a proportional pressure relief valve 140 which is connected on the input side to the hydraulic tank 160 and whose variable output pressure determines the applied control pressure at the two pressure relief valves 130, 130'.
  • the proportional pressure limiting valve 140 is actuated by the control device of the overload protection function of the discharge of the crane 10 detected by the Ausladungssensor and the determined by the load hook position detecting device position of the crane hook, so that the opening of the two pressure relief valves 130, 130 'and thus the on the Speisyaktechnischen 120, 120 'applied system pressure in dependence on the crane outreach and the crane hook position or the thus each allowed limit torque is determined on the slewing.
  • the proportional pressure limiting valve 140 can be regulated by a controller 141.
  • the proportional valve 140 is automatically regulated in such a way that the holding torque measured by the slew drive corresponds to the approved crane load.
  • FIG. 2 a 2/2-way valve 150, which is incorporated in the control pressure line between the proportional pressure relief valve 140 and the two pressure relief valves 130, 130 '.
  • This directional control valve 150 is designed such that it must be energized for a switched flow.
  • the switching valve 150 includes a position sensor or switch 151, which indicates the position of the switch 150 and is controlled by the system, so that an error monitoring is possible.
  • the overload protection can be deactivated, for example, if the load hook is located above the platform 20. On the other hand, the overload protection can then be activated and the holding torque on the slewing gear 30 is reduced depending on the projection and position of the hook when the load hook is below or outside the platform 20 in a position that increases the risk potential for the boom system or the crane could mean 10.
