Definitions

  • the invention relates to a method and a device for securing container crane systems in case of overload.
  • EP 1 710 199 A1 describes a container crane system with a service brake on the drive shaft of the engine or the input shaft in the transmission and a safety brake on the transmission output shaft or on the cable drum.
  • US 4 462 570 A describes an overload protection in a crane system in general and US 4,226,403 also generally describes an overload protection in pneumatically operated lifting systems.
  • Fig. 2 shows a standard hoist 1 for container crane systems, the two hoists with coupled via a gearbox 2 identical drive and output strands 3, 3 'and 4, 4', wherein in the following only the left hoist is explained.
  • a drive motor 5 is rotatably connected via a drive shaft 6 with a brake disc 9 and this with a transmission input shaft 8 of the transmission 2.
  • a service brake 11 is provided with spring-loaded brake shoes and a brake release device, not shown.
  • the transmission 2 drives via transmission output shafts 12 cable drums 14 with a cable 15.
  • a brake disc 17 is fixed to which a safety brake 18 engages with spring-loaded brake shoes, where an unillustrated brake release device is provided.
  • the cables 15 are attached to a head block 16, a substantially rectangular frame, on which a spreader is received, which receives a not shown container via corner fittings.
  • the head block 16 is referred to as conveyed or as a load.
  • the service brake 11 operates during operation to decelerate the load with a relatively high duty cycle, while the safety brake 18 is switched on only at the beginning of operation and off at the end of the operation, unless during operation no emergency stop due to a failure of the crane operation occurs , If, due to the failure of a component in the drive train, an overspeed on the drive shaft 6 or on the transmission output shaft 12 detected or emergency stop the system by another fault is necessary to close the Safety brakes 18, 18 'and the service brakes 11, 11' by an emergency stop signal issued by the crane operator. For reasons of construction, the safety brakes 18, 18 'have a shorter closing time than the service brakes 11, 11', so that the safety brakes 18, 18 'close earlier and thus absorb the load that acts on the hoisting ropes.
  • FIG. 3 A more recent system is in DE 10 2006 003 832 described in Fig. 3 is reproduced.
  • Fig. 3 are the same reference numerals for the same or corresponding components as in Fig. 2 used.
  • an overload clutch 7, 7 ' is provided, which is designed for a specific, maximum transmittable torque from the engine 5 to the transmission input shaft 8. If this torque is exceeded, the two coupling halves of the overload clutch 7 separate, so by disconnecting of the engine 5 no more drive torque on the Transmission 2 is transmitted.
  • the opening of the overload clutch 7 activates an overload sensor which emits a signal to a controller, which then interrupts the crane operation or stops by trigger signals to the service brakes 11, 11 'to the transmission input shafts 8 and the safety brakes 18, 18' on the cable drums 14th to block the powertrain and the power train. This prevents that decoupled from the motor 5 load 16 automatically lowers by gravity.
  • the brakes 11 and 18 are designed as industrial brakes, close the spring loaded and can be solved by a suitable brake release device, which works against spring force.
  • Such Bremsllusterra work in many cases electro-hydraulically, ie an electric motor builds on a hydraulic pump to a hydraulic pressure acting on a spring working piston, which optionally releases the brake at sufficiently high pressure via a lever linkage.
  • the safety brake 18 can also be designed as a directly hydraulically releasable safety brake.
  • overload clutch 7 takes a certain amount of time until the coupling halves of the overload clutch disconnect in case of overload.
  • Overload clutches also have a very high spread range until they react when an overload occurs. Accordingly long may trigger the overload sensor, which detects the opening of the overload clutch 7, and then to give a signal to the controller, which in turn gives trigger signals to the brakes 11 and 18 and stops the crane operation.
  • the controller which in turn gives trigger signals to the brakes 11 and 18 and stops the crane operation.
  • a correspondingly high tension of the hoisting ropes 15 which results from the maximum transmissible torque of the overload clutch 7.
  • the safety of container crane systems to be improved and above all the time to restart the hoist to be shortened when the hoist was stopped because of overload.
  • an overload or an approaching overload is detected and the safety brake on the cable drum and a blocking brake provided on the motor drive shaft are triggered by the sensor blocking the motor.
  • a method for overload protection of a hoist for a container crane system comprising two identical hoists on both sides of a transmission each with a drive motor, the drive shaft is connected to a transmission input shaft, and a safety brake on a cable drum on an output shaft of the transmission, wherein the Drum-guided hoist ropes are connected to a load or with a container-receiving head block, and wherein when lifting and moving a raised container by at least one sensor Studentslasat or an imposing overload is determined and the safety brake on the cable drums and provided on the motor drive shaft Locking brake is triggered by the sensor, which stops the flywheel of the engine.

  • the impending overload detecting sensor early a possible overload is detected, so that the hoist can be stopped before the Overload occurs.
  • An overload is determined by a specific value of the load that must not be exceeded to protect the crane system. In the prior art, when this overload occurs, crane operation is stopped. According to the crane system is stopped before reaching the overload value, for example, when 80% of the overload value is reached

  • at least one inclination angle sensor and / or at least one acceleration sensor are attached to the head block of the hoist in order to be able to detect an imminent overload as early as possible.
  • the blocking brake and the safety brake are triggered before the overload case occurs.
  • a tilt angle sensor and an acceleration sensor on the head block.
  • an inclination angle sensor and an acceleration sensor are provided in the area of each hoist on the head block.
  • the crane system can be quickly and easily returned to the operating state after an emergency stop of the hoisting gear because the operational readiness of the crane system can be restored by electronic signals without an overload clutch must be closed again.
  • the crane system can be solved alternately by a predetermined program, the locking brake on the drive motor and the safety brake on the cable drum and closed again.
  • This program can be executed very quickly, so that the crane system is ready for use again in a short time.
  • the operational readiness of the hoist is signaled by the sensors, which indicate that a previously recorded initial state has been reached again.
  • the fact that the hoist is stopped before the overload occurs, too occurring tensions held lower than in the prior art, when the overload has already occurred, which in addition to a sparing of the crane system by lower tensions a quick restart of the hoist is favored.

  • a brake to be hydraulically ventilated by a control block no resistances for the hydraulic fluid to overcome when reducing the hydraulic pressure, as is the case for example in an electro-hydraulic brake release device by the hydraulic pump.
