Definitions

  • the invention relates to a hoist of the preamble of claim 1 corresponding type.
  • Drilling device or a Bohrungsverschluß designed, for example, from a floating platform, on the seabed or in or on a borehole: They have a rotatably mounted winding drum on which a usually designed as a steel cable flexible traction means is attached, the up by rotational drive of the winding drum or can be processed.
  • At least one rotary drive device is provided.
  • the latter regularly includes an electric motor. But it is also possible to use a hydraulic or pneumatic drive instead of the DC motor.
  • Such elevators For braking the winding drum during the discharge of the load and for holding the load above the ground, such elevators have a braking device comprising a mechanically acting brake assembly.
  • a mechanically acting brake assembly In order to relieve this mechanically acting brake arrangement, it is also possible to provide further, non-mechanically acting brake arrangements, for example eddy current brake arrangements.
  • the lifts are in practice adapted constructively to the maximum expected lifting capacity determined by their intended use.
  • the latter is specified by definition for a first layer of rope on the winding drum.
  • the maximum lifting power is reduced by the associated larger lever, under which the load acts on the winding drum.
  • the rope is dimensioned so that its breaking load at least twice the lifting load of the elevator corresponds.
  • the superstructures over which the rope is deflected - for example a mast - are designed for a 1.8-fold lifting load.
  • the braking device is designed so that the maximum load to be held 1.5 to 1.6 times the lifting load corresponds.
  • a hoisting gear which in addition to a brake arrangement comprises an emergency brake device for generating an additional braking force.
  • the brake and the emergency brake assembly are configured such that they each achieve at least one hundred percent of the maximum required braking force.
  • the invention is therefore based on the object to improve the reliability of such lifting equipment.
  • the braking devices used previously which - as described above - provide protection against the overload of other components, and in the vast majority of applications ensure trouble-free operation, continue to be used.
  • Due to the additional emergency brake now the possibility is created in case of need, d. H. at currently insufficient braking power to be able to apply an additional braking force.
  • the emergency brake devices are those devices which are provided in addition to the brake device and are not simply larger in size, the emergency brake devices are only activated when they are actually needed. A deceleration of the winding drum is thus possible even in a total failure of the braking device.
  • the brake and the emergency brake arrangements are designed such that at least one hundred percent of the maximum braking power required can be achieved with them.
  • the emergency brake assembly can completely replace the brake assembly, so that emergency operation of the elevator is possible even with complete failure of the brake assembly.
  • a control device determines the respective braking power setpoint with a braking power actual value achieved by the main brake arrangement compares the characteristic parameters and, in the case of a differential value brake setpoint - braking actual value> 0, activates the emergency braking device so that the difference value corresponds to approximately 0, the maximum total braking power being ⁇ 130% of the braking power setpoint. Reduces the achieved with the main brake assembly braking power below the target value, the emergency brake assembly is activated to generate the additional braking power required via the control device.
  • Limiting the total braking power to a maximum of 130% of the target value avoids the forces exerted on the components of the elevator or other components by the application of braking power reaching values above the breaking load of these components, thereby avoiding the risk of damage by introducing excessive braking power becomes.
  • the brake assembly has at least one brake shoe acting on a rotating part and means for applying the at least one brake shoe and means for applying at least one brake shoe with a braking force, wherein the emergency brake assembly is formed by a Additional device is provided for selectively exerting an additional braking force on the rotary part. If the brake line which can be achieved with the brake arrangement during normal operation no longer suffices, an additional braking power can be actively generated by actuation of the additional device.
  • the device for acting on the at least one brake shoe with a braking force preferably comprises a spring arrangement acting on the at least one brake shoe with the braking force.
  • the device preferably has an arrangement acting in opposition to the spring arrangement for controlling the braking force exerted on the brake shoe.
  • the ancillary device is then preferably designed such that it comprises an arrangement for displacing the seat receiving the reaction forces of the spring arrangement. Upon actuation of the auxiliary device is therefore the bias the spring arrangement increases, which leads to an increase in the braking force acting on the at least one brake shoe and thus to an increase in the braking power.
  • the additional device is preferably designed as a hydraulically actuated device.
  • the emergency brake assembly comprises an additional braking device which can be selectively connected to the brake assembly.
  • the structure of the emergency brake assembly may at least substantially correspond to that of the main brake assembly.
  • the elevator comprises at least one gearbox coupled on the input side to a drive motor and cooperating on the output side with a summation gearbox, it is possible to arrange the emergency brake arrangement on the input side and / or the output side of the gearbox.
  • the emergency brake assembly is constituted by a release device for controlled or controlled release, retention or recovery of the load by the discharge device having a capacity suitable for braking and maintaining the maximum lifting capacity of the elevator.
  • the Nachlunvorraum preferably comprises an electrically, hydraulically or pneumatically driven engine, which also provides the application of emergency braking power serves. Also includes the Nachlrudvorraum a gearbox to which the engine is coupled, the engine can be coupled via an additional gear shaft coupled to the transmission. However, it is also possible to couple the motor to the input shaft of the transmission for a main drive motor for the elevator.
