Definitions

  • the invention relates to a hook block for a crane, preferably for a vehicle crane, according to the preamble of claim 1.
  • a hook block is the connection between the hoisting rope of a crane and the load.
  • the hook block has a lower part, on which a correspondingly shaped hook is attached rotatable and tiltable.
  • pulleys which are hereinafter referred to as rollers, arranged on a shaft.
  • rollers arranged on a shaft.
  • hook hooks with different roller sets are now to be used. For this purpose, a number of different hook bottles must be made and kept in stock.
  • US 2004/0084917 discloses a bottom tank system for a given maximum load, for forming differently loadable bottom bottles for a crane.
  • the object of the invention is to minimize the production cost and storage for hook bottles.
  • this object is achieved by claim 1, wherein in a generic hook block for a crane with a lower part on which the hook is rotatably and tiltably attached, and an upper part in which the rollers are mounted, on the at least one hoist rope is einscherbar ,
  • the roles are summarized in several modularly connectable sets of rollers. According to the invention, therefore, different bottles can be constructed on a modular basis from the individual modules. This increases the flexibility in the use of guided hook block, since the individual modules of the hook block for different uses can be combined differently.
  • rollers are connected via a hook beam with the hook.
  • a pair of two sets of rollers with different numbers of rollers can be connected here.
  • the roller sets are each bolted together. This makes it easy to put together the different roller set constellations.
  • roller sets only a part of the roller sets can be connected to one another in a different combination.
  • a large number of hook bottle constellations can be put together.
  • the respective roller sets can be combined with each other.
  • different hooks and hooks are to be used.
  • a hook bottle 10 is shown in the modular construction according to the invention.
  • a hook 12 is pivotally mounted about a pivot bearing 14 in a Hakentraverse 16.
  • the hook traverse 16 forms together with the pivotally mounted hook 12, the lower part of the hook bottle 10.
  • the upper part of the hook bottle 10 is formed by a plurality of modularly interconnectable roller sets 18, 20, 22 and 24.
  • These roller sets can be modularly connected to each other, wherein the connection is usually done here via a bolting.
  • the roller sets 18 and 20 or 22 and 24 are provided with an equal number of rollers.
  • the roller sets 18 and 20 each have seven rollers 26, while the roller sets 22 and 24 each have five rollers 26.
  • the roller sets 18 and 20 each have seven rollers 26, while the roller sets 22 and 24 each have five rollers 26.
  • roller sets 18 and 22 on the one hand and 20 and 24 on the other each other bolted, which are each bolted to the hook beam 16 such that a pendulum motion is allowed.
  • On the hook traverse 16 opposite side of the two combined sets of rollers 18 and 22 or 20 and 24 via a bracket 28 are interconnected.
  • the different number of rollers 26 in the roller sets 18, 20, 22 and 24 makes it fundamentally possible to represent different hook bottles 10, in the embodiment according to FIG. 1 the hook block 10 is constructed so that two hoisting ropes can be reeved by two winches. This is necessary because a single hoist rope length would not be sufficient to lower the hook block 10 to the ground. This means that both winches (not shown here) are in parallel operation. About the hook beam 16, the different running behavior of the two winds is compensated.
  • FIG. 2 an exemplary modular assembly of the hook block 10 is shown.
  • the roller sets 18 and 20 are coupled together so that they act as a single set of rollers.
  • the roller sets 18 and 20 are rigidly coupled together.
  • the hoisting ropes 30 are shown here on one side in the form of a so-called diagonal pull with an angle of> 4 °.
  • FIG. 3 Another example showing a hook block 10 composed of the roller set modules 18 and 20 is apparent FIG. 3 .
  • the roller set modules are oscillating connected to each other, so that in turn a rope length compensation can be done if here two hoisting ropes, which run over two winches, are reeved.
  • FIG. 4 an example of the hook block 10 is shown, in which the two narrow roller sets 22 and 24 are used. They are bolted together in the manner shown here. At this a hook traverse 16 can be angeolzt with hooks 12.
  • This hook block 10 composed of the narrow sets of rollers 22 and 24 can, together with a hook bottle, as for example with reference to the FIG. 2 has been shown, the hook bottle 10 according to the FIG. 2 is used on a main jib tip of a vehicle crane, while this according to FIG. 4 Hook hook shown as the second additional hook bottle on the luffing tip of a vehicle crane is used.
  • a second hook 12 must be used, but the roller sets, as originally in the expansion stage according to FIG. 1 were provided and are possibly carried along, are connected in a modular manner, so that the two examples according to the FIG. 2 and the FIG. 4 arise and can be used at the same time in a vehicle crane.
