Definitions

  • the invention is directed to a device for lifting coils, coils or the like.
  • a support bolt that can be inserted into its inner opening and several clamping segments that are vertically movable on its outer circumference and thereby radially expandable.
  • Such coils 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 over 100 kg even with smaller versions, must be hoisted. 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 smaller 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 often serve other purposes in the handling of such coils.
  • a device of the aforementioned type is calculated for these tasks, in which an axially protruding axially parallel guide rail is anoranet on the circumference of the supporting bolt for jeoes clamping segment, which engages in a longitudinal guide slot of the clamping segment and carries at least one tangential transverse bolt, which has an L arranged obliquely to the longitudinal axis ourchcode angiocn in the clamping segment, wherein the Tragoolzen have Olzen effective in its radially inner upper position locking means relative to the supporting D an outer cone as a sliding guide for an inner cone of the collet segments and the clamping segments.
  • Such a device practically consists only of arei units, the supporting bolt, the clamping segments mounted on these and the locking device. It is consequently simple and inexpensive to manufacture and reliable in its handling, and it can be designed with an extraordinarily small outer diameter of the clamping segments in that the clamping segments are mounted directly around the central supporting bolt. This makes it particularly suitable for handling coils with a small diameter in the inner opening.
  • the supporting bolt 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 in the case of the inner expansion movement inwards so that they are not only led through the inner 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 the inner opening of the coil. In this position, the locking device for the tensioning segments can then be unlocked against the oem support bolt, so that the tensioning segments fall off and are not spread out outside. When the support pin is subsequently raised, the clamping segments then grip firmly on the inside of the coil opening, the weight of the coil increasing the frictional force between the clamping segments and the coil in a known manner.
  • a particularly useful locking device consists of an axially parallel pin arranged at the head of a jeoen clamping segment, penetrating an opening in the bell, and a releasable locking bolt which engages on the outside of the bell 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 remains on until these clamping segment heads are seated. the coil can be retracted into this, whereupon the locking for the clamping segments is 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 performed twice, which causes an exact guidance of the clamping segments.
  • the device consists of a central support pole 1, at the upper end of which a support eye 2 is fastened, by means of which the device can be attached to a HeDezeug.
  • 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 serves 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 1 4 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 angle of inclination 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 and 12 of the clamping segment carrier 9.
  • In the lower end of the guide rail 4 there is a attached inner cone 17, 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 boa 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 with respect to the pin 29. If the pin 29 lies against the stop 32, as can be seen in FIG. 5, the bolt 28 of the bottom 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 in such a way that the bolt 28 emerges from the catch 30 of the individual pins 25, 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 has a further elongated hole 38 in the two parts 11 and 12 of the carrier 9 of the clamping segment 3 penetrates.
  • the clamping jaws 35 are connected to the friction lining 36 via the intermediate pieces 37 and 38 with the carrier 9.
  • Figures 1, 6 and 8 show the device in a position with retracted clamping segments 3.
  • the pins 29 are locked in their upper position by the bolt 28 in the bottom 26 of the rotary cap 25.
  • the clamping segments 3 lie on the minimum circumferential circle.
  • the device is moved a coil 4 1 in the inner opening 4 0 until the level 42 of the head 14 of the support surface 41 comes to rest 9 43 of the coil.
  • the locking device for the pin 29 is relieved, and the rotary cap 25 can be pivoted so far by means of its hand hub 31 that the bolts 28 release the pin 29. Due to its own weight, the clamping segments 3 then fall off until their friction linings 36 come to rest on the inner wall of the coil 40.
  • 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 outward 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 Mab 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 with respect to the central axis of the device.
