Definitions

  • the invention relates to a ballast device for attachment to the rear of a crane superstructure, in particular a crawler crane, with a base plate and a plurality of stackable ballast plates.
  • the rear ballast or ballast in general is the reduction or compensation of the acting tilting moment.
  • the rear ballast in the crane is usually located on the rotatable top and in the opposite direction to the load. In the caterpillar crane, the rear ballast is so far fixed to the rear of the superstructure.
  • the forces and moments acting on the machine may change abruptly, for example by increasing or decreasing the load on the load.
  • Stationary tail ballasts do not allow flexible adaptation to the changed operating conditions. Increases, for example, the effective tilting moment by increasing the working radius, so the stability of the Machine off because the balancing rear ballast torque remains constant due to the fixed position of the ballast to the superstructure. Remedy only a complex increase in the ballast weight by receiving more ballast plates.
  • ballast devices are already known from the prior art.
  • a solution for adjusting the rear ballast during crane operation is in the EP 2 281 771 A1 disclosed.
  • the rear ballast is moved horizontally over a complex rail or telescopic mechanism, ie the ballast can either be approached closer to the crane superstructure or alternatively moved further away.
  • the overall machine width is usually defined by the rear ballast.
  • the rear ballast When passing through bottlenecks on the construction site, it may therefore be necessary to disassemble the rear ballast, which unnecessarily increases the resulting set-up time and thus reduces the operational readiness of the machine.
  • a solution to this problem that makes the costly disassembly superfluous, is not known from the prior art.
  • the object of the present invention is therefore to show a novel construction of a Ballastiervoriques for a rear ballast, which knows how to overcome the above problems.
  • ballast device for attachment to the rear of a crane superstructure according to the features of claim 1.
  • Advantageous Embodiments of the ballast device are the subject of the dependent claims subsequent to the main claim.
  • a ballast device for attachment to the rear of a crane superstructure in particular a crawler crane
  • a base plate on which one or more connection points, preferably Verbolzstellen, are provided for mounting on the rear of a crane superstructure.
  • connection points preferably Verbolzstellen
  • at least two support plates are hinged to the base plate pivotally about vertical axes.
  • the support plates may be pivotably articulated about a common pivot axis, but are preferably offset from each other separate pivot axes of the support plates.
  • the carrier plates serve to receive and stack individual ballast plates. It is a particularly simple construction of a movable rear ballast shown whose production and assembly compared to the known solutions from the prior art is less expensive and therefore less expensive. In addition, this device allows flexible adaptation of the total width of the ballast. In this case, it is preferable that the carrier plates are rearwardly, i. in assembly position, pivot behind the rear of the crane or behind the base plate.
  • these can each be pivoted about 90 ° in the direction of travel behind the base plate.
  • the width dimension of the ballast device can be significantly reduced temporarily and thus the track width can be reduced in certain crane models.
  • a passage of bottlenecks on the construction site can be possible without dismantling the ballast. This saves set-up time and thus increases the operational readiness of the crane.
  • the carrier plates are each pivotally connected via a support arm hinged to the base plate.
  • the articulation of the support arm is preferably via a finger-fork connection with the base plate.
  • the drive of the carrier plates or the carrier arms can be effected via a common actuator, in which case both carrier arms are actuated or pivotable synchronously with each other.
  • separate actuators can be used to provide a separate actuation of the carrier plates can.
  • the actuator is a rotary drive is used, for example, drives the pivot axis of the support arms directly.
  • a linear drive preferably in the form of a lifting cylinder apply.
  • gear means are necessary to convert the linear motion into the rotational movement.
  • the actuator or drive can be electric or hydraulic.
  • the lifting cylinder used is preferably equipped with a lowering brake.
  • a rotary drive which can be equipped with adequate braking or fixing means.
  • the one or more actuators and any mechanical coupling means are at least largely stored on the base plate.
  • any connection points for the power supply of the actuators may be arranged freely accessible on the base plate to ensure easy installation of the ballast on the crane superstructure including the connection necessaryy power supply lines to power the one or more actuators from the upper or undercarriage.
  • At least one pinion per carrier plate which can be driven by the actuator or actuators is provided, which meshes directly or indirectly in an associated toothing of the carrier plate or of the carrier arm or drives it.
  • the spur gear can be single or multi-stage, especially if an adjustment of the direction of rotation for the respective support arm is necessary.
  • the at least two pinions are mechanically connected to one another via a coupling rod in order to transmit the rotational movement of a pinion to the coupled pinion.
  • both pinions can be driven synchronously by a single actuator.
  • At least one pinion comprises a firmly connected actuating lever for coupling to the piston rod of an actuator in the form of a lifting cylinder.
  • the linear movement of the piston rod can be converted particularly easily into a rotational movement of the pinion.
  • the lifting cylinder is also articulated movably on the base plate.
  • a suitable sensor for measuring the ballast position can be constructed for example in the form of a sensor for measuring the angle of rotation of a rotary drive or for measuring the pivot angle of the carrier plates.
  • a sensor for measuring the angle of rotation it makes sense to carry out this with a redundant cam limit, which serves to secure the angle measurement.
  • the use of a sensor for detecting the stroke of an actuator in the form of a lifting cylinder offers.
  • the present invention also relates to a crane, in particular a crawler crane, with an uppercarriage and at least one ballasting device arranged at the rear area according to the present invention.
  • the crane thus has the same advantages and properties such as the ballast according to the invention, which is why at this point can be dispensed with a repetitive description.
  • the crane comprises a crane control, which calculates the influence of the position of the carrier plates and the associated center of gravity displacement on the possible load capacity of the crane. This makes it possible to use this influence also for the load torque limit of the crane control, so that it can always be optimally adapted to the current ballast situation.
  • FIGS. 1a, 1b This is suitable for attachment to the rear of a crane superstructure, so that the ballast 10 and the ballast 23 is arranged in the opposite direction to the load on the crane and counteracts the tilting moment acting through the load.
  • the ballast 10 is thus a rear ballast.
  • the device 10 comprises a base plate 20, on which two ballast towers 21, 22 are arranged pivotably.
  • the ballast towers 21, 22 each comprise a plurality of ballast plates 23 stacked on one another.
  • the base plate 20 can be the ballast 10 usually mounted on the crane superstructure, for example, bolt on suitable Verbolzstellen on the superstructure frame.
  • FIG. 1a shows the ballast 10 in the regular starting position in which the ballast towers 21, 22 are pivoted to the side.
  • the ballast 10 corresponds to a conventional rear ballast on crawler cranes with respect to the physical dimension, which is mounted at the rear of the superstructure.
  • Figure 1 b is the core idea of the present invention, according to which both ballast towers 21, 22 are pivotable backwards. In this position, the distance between the superstructure and ballast plates 23 is maximum, so that the overall center of gravity of the ballast plates is changed relative to the crane.
  • the concrete structure of the ballast 10 is now based on the Figures 2 . 3 be explained further.
  • the pivoting rear ballast 10 is based on the base plate 20, on the via a finger-fork connection 27 support arms 24, 25th pivotable about the vertical axes A, A 'are hinged.
  • At the free end of the support arms 24, 25 support plates 7, 8 are provided, on the surface of ballast plates 23 are stackable.
  • the base area of the carrier plates 7, 8 essentially corresponds to the base area of the ballast plates 23.
  • Both support arms 24, 25 are thus pivoted about laterally offset vertical axes A, A '.
  • a lifting cylinder 9 The piston rod or the eye of the piston rod of the lifting cylinder 9 is pivoted at the end to an actuating lever 11 of the first pinion 1 pivotally. As a result, the linear movement of the lifting cylinder 9 is converted into the necessary rotational work of the pinion 1.
  • a coupling rod 6 is also rotatably mounted, which serves for transmitting power via the lifting cylinder 9 applied force to a second pinion 2.
  • This pinion 2 also includes an actuating lever 26 which is pivotally connected to the coupling rod 6 at the end.
  • the toothing of the pinion 2 engages in a further gear 4 that the toothing 5 of the left support arm 24 meshes.
  • the pinion 1 meshes accordingly with a toothing 3 of the right support arm 25.
  • the load torque limit of the crane control can be optimally utilized in each ballast position.
  • either the stroke of the hydraulic cylinder 9 or the angle of rotation of the ballast towers 21, 22 can be measured.
  • the hydraulically operated lifting cylinder 9 is equipped with a lowering brake.
  • the rotary encoder is equipped with a redundant cam limit switch to safeguard the angle measurement.
