Definitions

  • the invention relates to a device for hanging a rail, in particular a downwardly open hollow profile-shaped rail of a suspension crane, according to Claim 1.
  • the commuting Suspension is ensured by the straps at the ends Ball heads and complementary ball sockets on the rail or are attached to the structure. With the pendulum suspension in particular shock loads on the rails in vibration energy transformed; the rails take the form of damped vibrations back to their starting position.
  • the object of the invention is to provide a rigid suspension of a rail, in which horizontal forces, especially impulses, are strongly damped.
  • the invention provides for a device for hanging a rail on a Structure with one end and one end of the rail attached tension element before that between the structure and the tension element
  • Rubber-metal element with two spaced apart essentially horizontal metal supports is provided on their facing each other Inner surfaces of the rubber is attached, the structure being with the lower Metal support and the other end of the tension element with the upper metal support connected is.
  • the flow of force goes through the tension element to the upper metal support, the is supported on the rubber.
  • the rubber formed as an intermediate layer in turn lies on the lower metal support, which is attached to the structure. The intimate connection between the rubber and the inner surface of the metal carrier prevents the metal supports from moving freely against each other.
  • this connection is related to the elastic rubber ensure that horizontal force peaks that occur in pulses are absorbed, d. H. be dampened. You will be in dampened vibrations with very low amplitude converted.
  • a compact rubber-metal element with even distribution of the load is achieved by an embodiment in which that with the upper metal support connected end of the tension element by leaving a space through a vertical opening of the rubber-metal element is guided.
  • a rigid connection between the tension element and the metal support is obtained by Use of a spacer that lies against the upper metal support and through which is the end of the tension element.
  • the spacer element is expediently additionally on the upper one Metal bracket attached.
  • the spacer is vertical arranged hollow cylinder, the end face attached to the upper metal support is.
  • the end of the tension element which is firmly connected to the upper metal support is in the Area of the lower metal carrier with an external thread on which one the spacer against the upper metal support nut is screwed on to a stable and non-compliant with horizontal forces To achieve connection between the metal support and tension element.
  • Fig. 1 and Fig. 2 show a device for hanging a downwardly open hollow profile rail 1 z. B. for a suspended crane.
  • the rail is by means of a Traction element 2 via a rubber-metal element 3 on a as a T-beam 4a trained structure 4 attached.
  • a U-shaped cross member 5 For fastening the rubber-metal element 3 on the T-beam 4a is a U-shaped cross member 5, which with its upper edges 5a abuts the lower outer surface 6 of the T-beam 4a.
  • the firm connection between the flange 6a and the cross member 5 is made via tabs 7, the located on both sides of the web 8 on the inside of the flange 6a and on the cross beam 5 extending beyond the flange width.
  • Fig. 3 shows in a simplified plan view that for each suspension seen in the longitudinal direction of the T-beam 4 two cross beams 5th are arranged parallel and spaced apart so that the screws 9 Corner points of an imaginary square (rectangle is of course also possible) form. In the center of the square there is a tension element 2 in the case of two cross beams 5 attached.
  • the U-shaped cross section of the crossbeam can be clearly seen in FIG. 2.
  • the cross beams 5 are fixed connected to the rubber-metal element 3.
  • the rubber-metal element 3 consists of two spaced apart essential horizontal metal beams 11a, 11b, which are designed as metal plates are. 3 shows in particular that the metal carrier 11a has a circular disc central opening 12 is. The central opening 12 is vertically spaced above one central opening 13 of the lower metal carrier 11b arranged. Seen from above the lower metal beam 11b extends in opposite directions across the Outside contour of the metal carrier 11a also. Between the metal supports is another mutually facing inner surfaces and a rubber plate 14 arranged attached. The attachment is done in the embodiment by vulcanizing the Rubbers on the metal supports 11a, 11b. Of course, it can Rubber can also be any other elastic material that is not must be vulcanized. It is equally conceivable that the elastic Material is glued to the inner surfaces of the metal carrier 11a 11b. That too Rubber is plate-shaped, is only a special embodiment of the rubber-metal element 3rd
  • the rubber plate 14 also has an opening aligned with the openings 13, 14, so that the tension element 2 through the thus formed, in the vertical direction extending total opening can be pushed through.
  • the lower metal support 11b is attached by means of screws 10 and spacer elements 15 the cross members 5 screwed and thus via the cross member 5 with the structure 4th firmly connected.
  • the tension element 2 is at one end 2a with an external thread 2b provided with this end 2a through the openings 12 and 13 and attached to the upper metal support 11a.
  • the attachment takes place here by means of a Nut 16, which is screwed onto the end 2a and also at the top Metal support 11a is soldered or welded. The latter is not essential required, but makes handling easier.
  • FIGS. 1 and 2 additionally provided as a hollow cylinder spacer 17 by which is inserted through the end 2a of the tension element 2 and which at the Inner surface of the upper metal support 11 a rests with its end face.
  • the overhead crane During the operation of the overhead crane, they are vertically up and down directed tensile and compressive forces through the rubber-metal element 3 as in a rigid connection transferred to the structure.
  • pulse-like horizontal force peaks for example due to impacts, cause the upper metal support 11a compared to the lower metal support 11b due to the move elastic effect of the rubber 14 against each other.
  • This elastic Deformation of the rubber 14 intercepts the pulse peaks.
  • the rubber-metal element 3 acts as a quasi-rigid intermediate element, which essentially only horizontal forces shows its elastic properties.
