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 suspension device and at the other end to the belt drum, the corresponding end of the suspension element in an insertion slot for the suspension element having, extending transversely to the suspension means at least the load-bearing means and is guided around a arranged in the recess, the cross-sectional shape of the recess and is pressed by the clamping element against the inner wall of the recess.
  • suspension element For example, in small hoists it is known u. a. also to use flat tapes 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-carrying 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.
  • a small hoist is known with a flat band suspension means in the form of a textile band which can be spirally wound onto a winding roll, which carries loops at its ends and is fastened to a retaining bolt, the band drum having a recess provided with rounded corners for receiving the Has retaining bolt with the strap loop.
  • the tape is sewn or riveted accordingly at the ends. This means that a replacement tape in fixed lengths must be kept ready so that the replacement can be done in a short time.
  • the beginning of the band is then inserted into the longitudinal slot of the clamping sleeve, whereupon the clamping sleeve is rotated when the beginning of the band is clamped between the flanges that are pressed together, so that the band is wound onto the clamping sleeve to a degree given by the size of the holding force to be achieved.
  • the slotted adapter sleeve under the effect of its own elasticity, presses the band windings lying on it against the inner wall of the bore, which means that the beginning of the band is held in a frictional manner.
  • the intrinsic elasticity of a slotted adapter sleeve depends on the manufacturing tolerances, the curing conditions, the material properties etc. and can therefore fluctuate within unpredictable, relatively large limits, so that the size of the holding force exerted on the beginning of the tape cannot be precisely determined or checked in a simple manner. With larger and strongly changing loads, twisting of the adapter sleeve in the bore cannot be ruled out. This is insignificant in the case of loads occurring with magnetic tapes etc. due to their limited strength, but makes such a tape fastening device generally unsuitable for hoists. For these reasons, it must be ensured for safety reasons that the holding force with which the suspension element is held on the belt drum or the load suspension means is at least 2.5 'times the permissible maximum load.
  • the object of the invention is therefore to provide a fastening device for the band-shaped suspension element in hoists, in particular in small hoists, which, with a perfect guarantee of the required security against tearing out by a distinguished, space-saving and economically producible structure and allows a quick, easy replacement of the suspension element in the event of wear.
  • the fastening device mentioned at the outset is characterized in that the recess is designed as a bore in a manner known per se, that the clamping element can be expanded radially and contains an axial clamping screw penetrating the clamping element which can be screwed into an abutment and that Clamping element clamping elements are assigned, by means of which an axial clamping movement can be implemented in a radial widening of the clamping element.
  • the clamping element which is widened by the tightening screw, which can be tightened with a precisely determinable torque, causes a large-area jamming of the band end between the bore wall and the outer circumferential surface of the clamping element, thus ensuring that the band end is held in a frictional manner.
  • the clamping element can be an expandable clamping sleeve;
  • the clamping sleeve made of metal or plastic material, which carries at least one conical clamping surface on its inside as a widening means, which is supported on an associated conical surface of the clamping element, which is clamped axially against the conical clamping surface by the clamping screw.
  • the clamping element can be formed in two parts, both of its parts carrying a conical surface interacting with a corresponding conical clamping surface of the clamping element and the two parts of the clamping element being axially movable in opposite directions by the clamping screw are.
  • the arrangement is such that the clamping element is formed by at least one bolt or sleeve-like spring element made of elastic material which can be axially compressed by the clamping screw supported axially via a support element against the clamping element is.
  • the tensioning screw is tightened, the elastic material is pressed together in the axial direction, so that it deviates radially and presses the band end against the bore wall with great force.
  • the relatively high coefficient of friction of the elastic material of the spring element contributes to a further increase in the achievable holding force for the band end.
  • 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 through the insertion slot into the bore.
  • 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 receiving device of a small hoist in the form of a load hook 1 is shown, 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 band 3 is at the other end on a band drum 4 illustrated in detail in FIG. 4 anchored on which it can be wound spirally in a manner known per se.
  • a cylindrical bore 6 extending transversely to the tape 3, which is aligned parallel to the axis of rotation of the tape drum 4.
  • An externally cylindrical clamping element 9 (FIG. 2) or 9a (FIGS. 3, 5) is inserted in the bore 6 and its outer diameter can be changed by means of a clamping element 10 in the form of a clamping sleeve.
  • the end of the band 3 is inserted through the insertion slot 7 into the bore 6, then passed around the cylindrical clamping element 9 and 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 clad the insertion slot 7 at 16, with 8 in turn having the rounded insertion surfaces for the band 3.
  • the clamping element 9a according to FIG. 3 is inserted into the insert part 15, by means of which the end of the band 3 is clamped to the inner wall of the insert part 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 FIGS. 2, 3, 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.
