Definitions

  • the invention relates to a fastening device for the band-shaped suspension element of a hoist with a band-shaped suspension element which can be spirally wound onto a belt drum and which is fastened at one end to a load-carrying means and at the other end to the belt drum.
  • suspension element For example, it is known for small hoists, e.g. to use flat belts made of textile material as a suspension element. Such a band-shaped suspension element must be fastened both on the belt drum and on the load suspension means, such as a hook harness, in such a way that the required holding force is achieved with certainty and tearing out of the suspension element is impossible. In addition, the suspension element should be quick and easy to replace when worn.
  • an elevator has become known from DE-OS 21 36 540, in which as a support. medium also a band is used, which is clamped at the end between two holding plates, with additional securing provided by wedge pieces.
  • a support. medium also a band is used, which is clamped at the end between two holding plates, with additional securing provided by wedge pieces.
  • the object of the invention is therefore to provide a fastening device for the band-shaped suspension element, in particular for small hoists, which is characterized by a simple, space-saving and economically producible structure and a quick, simple replacement of the suspension element while ensuring the required security against tearing out properly Wear allowed.
  • the fastening device mentioned at the outset is characterized according to the invention in that the load-carrying means and / or the tape drum has a bore which has an insertion slot for the suspension means and is oriented transversely to the suspension means and in which a clamping element which is adapted to the cross-sectional shape of the bore is arranged, the outside diameter of which can be changed by means of a tensioning element and that the suspension means guided around the end of the clamping element can be clamped between the bore wall and the expanded clamping element.
  • the clamping element Since after the release of the tensioning element the band end can easily be removed from the bore and the end of a new band only has to be put around the clamping element, the replacement of the band-shaped suspension element is particularly simple with this fastening device. On the other On the side, however, the clamping element causes a large-area jamming of the band end between the bore wall and the outer peripheral surface of the clamping element, which ensures that the band end is held in a frictionally locking manner.
  • the clamping element can have an expandable clamping bush, for example made of metal or plastic material, which carries at least one conical clamping surface on its inside, which is supported on a corresponding conical surface of the axially press-in clamping element.
  • the clamping element can be pressed into the clamping element by means of an axial clamping screw.
  • the clamping element can be formed in two parts, both of its parts bearing a conical surface which interacts with a corresponding conical clamping surface of the clamping element and the two parts of the clamping element can be moved axially in opposite directions by the clamping screw are. Similar to an expansion dowel, very large radially outward forces can be transmitted to the clamping bush with such an arrangement, with the result that the band end is clamped with a correspondingly large force between the bore wall and the clamping bush.
  • the arrangement is such that the clamping element is formed by at least one bolt-like or sleeve-like spring element made of elastic material which can be axially compressed by the tensioning element.
  • the tensioning element itself can also be a tensioning screw penetrating the tensioning element.
  • a sleeve-like insert can be inserted into the bore, through which the insertion slot may also be at least lined and in which the clamping element is arranged.
  • This insert which is preferably made of plastic material, protects the band-shaped suspension element at the point where it is inserted into the bore through the insertion slot.
  • the maximum achievable holding force can be increased by this insert, while the tolerances in the production of the bore only have to meet minimal requirements.
  • the wall of the bore or of the insert can have a profiling which improves the mounting of the end of the suspension element.
  • the suspension element can be replaced quickly and easily when worn, the replacement band being cut off from a larger supply roll and being able to be used without additional end processing.
  • the whole device is very small and compact; it is simple and economical to manufacture.
  • a load suspension device of a small lifting device is shown in the form of a load hook 1, which is rotatably mounted in the usual manner on a housing 2, which in turn is attached to a suspension element in the form of a band 3 made of plastic-textile material.
  • the tape 3 is anchored at the other end to a tape drum 4 illustrated in FIG. 4, on which it can be spirally wound in a manner known per se.
  • the end of the band 3 is inserted through the insertion slot 7 into the bore 6, then around the cylindrical clamping element 9 or 9a (see. Fig. 1,4,5) and between the wall of the bore 6 and the outer peripheral surface of the means the clamping sleeve 10 expanded clamping element 9 or 9 a frictionally jammed.
  • the clamping element 9 is designed in the form of a longitudinally slotted clamping sleeve made of metal or plastic material, which carries on its inside two opposing conical clamping surfaces 11, which in turn are supported on corresponding conical surfaces of the two-part clamping element 10.
  • the clamping element 9a consists of a sleeve-like spring element made of elastic material, through the bore of which the clamping screw 100 screwed into the threaded hole 13 runs.
  • the clamping screw 100 is supported via a spring plate 14 against the clamping element 9a. If it is tightened, the elastic material of the clamping element 9a is axially compressed, so that the clamping element experiences a corresponding radial expansion, which causes the end of the band 3 to be clamped to the wall of the bore 6 in the manner already explained.
  • a sleeve-like insert 15 is inserted into the bore 6, which consists, for example, of plastic material and also completely lines the insertion slot 7 at 16, the rounded insertion surfaces for the band 3 also being present at 8.
  • the clamping element 9a according to FIG. 3 is inserted into the insert 15 , by which the end of the band 3 is clamped to the inner wall of the insert 15 in the manner already described when the clamping screw 100 is tightened.
  • the inner wall of the insert part 15 has a profile indicated at 17, by means of which the achievable maximum holding force of the fastening device 5 is increased. It would also be conceivable to provide such a profiling directly on the wall of the bore 6 in the embodiments according to FIG. 2, which is pointed out for the sake of order.
  • the clamping screw 100 is screwed into the threaded hole 13 provided in the bottom of the blind hole 6, it would also be conceivable to make the arrangement such that the hole 6 is designed as a through-hole and the clamping screw 100 carries a threaded nut which is supported on the side facing away from the screw head against the clamping element 9 or 9a.
