Definitions

  • the invention relates to a device for gripping coils, coils or the like.
  • a central support bolt which can be inserted into its inner opening and a plurality of guide rails projecting radially on its outer circumference, each axially movable in a longitudinal guide slot on the outer circumference of the support bolt and thereby radially following engage in the externally expandable clamping segment, the supporting bolt having an outer cone as a sliding guide for an inner cone on the clamping segments.
  • Coils of this type are wound on spools of winding machines, then bound and removed from the spool and transported to the place of their further processing. To do this, the coils, which often have a weight of more than 100 kg even with smaller versions, must be raised. Here, as with transport, the coil should be treated as gently as possible so as not to impair the unwinding during subsequent processing. It is particularly difficult to transport coils with a comparatively small diameter of the inner opening because the known devices are generally too large to be able to be inserted into such small inner openings of coils. The known lifting devices are also complicated in construction and expensive to manufacture, which is mainly due to the fact that they also serve other purposes in the handling of such coils at the same time.
  • a hydraulic, pneumatic or mechanical actuating device acting on the shaft of the supporting bolt is required, which makes it difficult to insert the chuck from above into a coil or the like set up with a vertical axis.
  • the handling of the device is made considerably more difficult and the additional actuating device makes it particularly complex.
  • Such a device practically consists of only three units, the supporting bolt, the clamping segments mounted on it and the locking device, while an additional housing into which the clamping segments and the supporting bolt are to be inserted is just as unnecessary as a mechanical, pneumatic or hydraulic drive.
  • the device according to the invention is consequently simple and inexpensive to manufacture and reliable in its handling, and it can be designed with an extraordinarily small outside diameter of the clamping segments by virtue of the fact that the clamping segments are mounted practically outside a housing directly around the central supporting bolt. This makes it particularly suitable for handling coils with a small diameter in the inner opening. It is of particular importance that, in the device according to the invention, the support bolt is not moved out of the clamping segments, so that additional axial freedom of movement is unnecessary for the support bolt and the entire considerably large axial length of the clamping segments is available for their engagement surface.
  • the support pin has a bell which overlaps the head of the clamping segments from above, into which the head of the guide rail engages and which has an inner cone as a sliding guide for an upper outer cone of the clamping segments.
  • This bell is used for the additional upper guidance of the clamping segments during their spreading movement inwards, so that they are not only guided through their elongated holes, but are also supported on the bell.
  • the outer diameter of the bell can be larger than the maximum diameter of the clamping segments, because when the device is moved into the coil to be lifted, the clamping segments alone engage in the inner opening of the coil. In this position, the locking device for the tensioning segments can then be unlocked with respect to the supporting bolt, so that the tensioning segments fall off and are thereby spread outward. When the support bolt is subsequently raised, the tensioning segments then grip firmly on the inside of the coil opening, the weight of the coil increasing the frictional force between the tensioning segments and the coil in a known manner.
  • a particularly expedient locking device consists of an opening in the bell arranged at the head of each clamping segment penetrating axially parallel pin and a releasable locking bolt on the outside of the bell engaging in a catch of the pin. If the device is moved into the coil, the lock is released and the pins are released so that the clamping segments can reach their lowering position.
  • a rotary cap is rotatably and axially immovably mounted on the support bolt above the cover plate of the bell, which has a common locking bolt for the pin of all clamping segments. When handling this common locking bolt, all clamping segments are locked or released at the same time.
  • the head of the clamping segments projects radially outward from their outer friction surfaces. This has the advantage that the device can be retracted into the coil until these clamping segment heads are seated, whereupon the locking for the clamping segments is then released. In this simple manner, the clamping segments form a stop which limits the movement of the device into the coil.
  • a parallel guide with two cross bolts and corresponding elongated holes is provided between each clamping segment and the associated guide rail.
  • the clamping segments are guided twice, which causes an exact guidance of the clamping segments.
  • the device consists of a central support bolt 1, at the other end of which a support eye 2 is fastened, by means of which the device can be attached to a hoist.
  • These guide rails 4 are arranged at a distance of 120 ° around the central support pin 1. At the lower end 7 of the support bolt 1, this has an outer cone 8 in the space between the guide rails 4.
  • Each guide rail 4 is used to support a clamping segment 3.
  • the carrier 9 of the clamping segment 3 has a longitudinal guide slot 10, which is bridged by the yoke 13 connecting the two parts 11 and 12 of the carrier 9.
  • the head 14 of the carrier 9 has an elongated hole 15, the longitudinal axis of which converges towards the end 7 of the supporting bolt 1. The degree of convergence corresponds to the pitch angle of the cone 8 of the supporting bolt 1.
  • the ends of a transverse bolt 16 fastened in the head 5 of the guide rail 4 protrude into the elongated holes 15 of the two parts 11 1 and 12 of the clamping segment carrier 9.
  • an inner cone 17 is attached, which lies flat against the outer cone 8 of the supporting bolt 1.
  • the outer peripheral surface 20 of the yoke 13 is conical in a manner corresponding to the pitch angle of the cone 8 and the angle of convergence of the elongated holes 15.
  • This outer cone 20 bears against the inner cone 21 of a bell 22 which engages over the head 5 of the guide rails 4 and the head 14 of the clamping segment carrier 9.
  • the two cones 20 and 21 form an upper sliding guide for the clamping segments 3 as the cones 8 and 17 represent a lower sliding guide relative to the central support pin 1.
  • the bell 22 is fastened to the support bolt in the region of the upper end thereof.
  • a rotary cap is rotatably but axially immovable on the socket 24 of the supporting bolt 1.
  • the bottom 26 of this rotary cap 25 has a window 27 at an angular distance of 120 °, in which a locking bolt 28 engages.
  • the rotary cap 25 has a lateral handle 31, by means of which it can be pivoted through an angle of approximately 30 °. This angle results from the position of the stops 32 and 33 delimiting the window opening 27 relative to the pin 29. If the pin 29, as can be seen in FIG. 5, bears against the stop 32, the bolt 28 of the base 26 of the rotary cap 25 engages the catch 30 of the pin 29 fastened to the clamping segment 3. If the rotary cap 25 is pivoted relative to the socket 24 of the supporting bolt 1 such that the bolt 28 emerges from the catch 30 of the individual pins 29, the pins 29 and thus the carrier 9 of the clamping segments 3 are released, so that they move into the position according to FIG 7 can fall off. The cone 20 of the yoke 13 slides on the inner cone 21 of the bell 22 and the inner cone 17 of the carrier 9 on the outer cone 8 of the support bolt 1. The axial length of this movement is determined at most by the axial length of the elongated holes 15.
  • the carrier 9 of the clamping segments 3 carries below the head 14 a circular arc-shaped clamping jaw 35 with an outer friction lining 36, e.g. made of hard rubber or the like
  • each guide rail 4 of the supporting bolt 1 has, in addition to the upper transverse bolt 16, a lower transverse bolt 37 which penetrates a further elongated hole 38 in the two parts 11 and 12 of the carrier 9 of the clamping segment 3.
  • the clamping jaws 35 are connected to the friction lining 36 via the intermediate pieces 47 and 48 with the carrier 9.
  • the clamping segments 3 remain in their lower position, and the cross bolts 16 move upward within the oblique elongated holes 15. As a result, the clamping segments 3 are moved further outwards on their conical guides and the engagement force of the friction linings 36 on the coil 40 is increased, so that this is reliably carried along when the device is raised further.
  • the extent of the spreading movement of the clamping segments 3 results from the axial length of the elongated holes 15 and the angle by which the longitudinal axis of these elongated holes 15 converge towards the central axis of the device.
