Field of application of the invention

The invention relates to a suspension head for confusion-free, power-train-oriented slat chain systems in the modular system, which are mainly intended for Heb on and transporting loads in metallurgy and construction.

Characteristic of the best known state of the art

For a long time, sling chains have been manufactured in which their intended use is determined by the manufacturer

the suspension link and the round steel chain are firmly welded by means of intermediate and / or transitional steel.

Meanwhile, it has gone over to giving the user the opportunity to assemble his sling chains themselves as needed. This is made possible by modular systems of sling chains, according to DE AS 2335131, which are designed so that only the user, for a certain carrying capacity, provided chains and accessories can be detachably connected to each other.

Significant importance for the unmistakable design of sling chain systems have the suspension heads according to DE OS 2235512, DE PS 2730838 and DE OS 2732246.

The demand for error-free assembly komi.Meh according to DE OS 2 235 512 already known suspension head, consisting of an annular suspension member and an unverlie. bar connected transition member in the form of a ring fork, for einundzweisträ'ngige stop chains after.

However, these known suspension heads become increasingly expensive and less robust with the number of chains to be attached in production.

It is also üin suspension head of the type mentioned above, which consists of a respective annular suspension member, which is welded to at least one annular transition or intermediate member, in turn the fork boot!

and / or Ringgabsln for the connection of the individual sling chains or connecting members are welded directly to certain Ab.Jssungen.First, with this solution, the problems of the former type eliminif to another is a connection between fork shackles or ring fork with chain links not possible.

Also known is a suspension head according to DE PS 2730838, in which each fork shackle or each ring fork is connected to the suspension member or with the associated transition member by a shackle, the shackle bolt connection is secured only immediately before delivery with a locking pin in a blind hole. The advantage of low costs for the storage of a certain number of different suspension heads here is the disadvantage of a weitau J higher cost of different forgings and thus costs compared.

Also known is a suspension head according to DE OS 2732246 mentioned type in which drop-forged in an annular suspension link transition or intermediate links are welded, which are coupled by means of a connecting lug to matching connecting or connecting members, such as a double fork link.

This invention reduces the cost of stocking on suspension heads, because the, otherwise welded into the suspension links, annular transition or intermediate links omitted, however, here are costs for a whole series of drop forgings, which are additionally necessary for mehrsträng'.ge sling chains ,

Furthermore occurring bending stresses of the transition member for multi-strand chain slings are not excluded, because due to the aligned holes a universal twistability and mobility is not guaranteed to a sufficient extent.

Object of the invention

The aim of the present invention is to create a confusion-free load-strand-oriented lifting head for sling chain systems with a minimum of accessories with a simple structural design.

Explanation of the Weoens of the invention

The invention has for its object to provide a suspension head, which is movable on all sides, and in conjunction with as few well-known forging accessories ensures a variable, designed according to the modular system load-strand-oriented sling chain system.

According to the invention the object is achieved in that the connecting element has the shape of a ring eye. The opening of the ring eye for welding in the suspension or. Transition or intermediate member and the bore of the eye for coupling with a fork-head-shaped component is axially offset by 90 °. The width of the eye of the connecting element is approximately equal to the thickness of the fork-head-shaped component. The width of the clevis slot of the fork-head-shaped component and the thickness of the eye of the connecting element are stepped such that in a certain clevis slot only one corresponding to the load capacity row provided connection is possible.

embodiments

Preferred embodiments of the invention are shown in the drawing. Show it:

Fig. 1: a suspension head for a four-strand sling chain suspension in view

2 and 3: a suspension head for a single-stranded sling chain with connecting element in view and in side view

Fig. 4: a suspension head for a two-strand chain stop in view.

In the embodiment of Fig. 1 is a suspension head for a four-strand chain suspension. On the suspension member 1, two transitional or intermediate members 2 are welded, in each of which two connecting elements 3 are also welded captive. By means of four preferably fork-head-shaped components 4 dk connection with the adjoining chain strands 5 is produced.

The Ausführungsbeispial shown in Figure 2 and in Figure 3 a suspension head for a trained on the modular principle load-strand-oriented single-stranded chain suspension or the like consists of an annular suspension member 1, in which a connecting element 3 is captively welded. At its, offset by 90 ° to the ring, lobe-shaped eye 8, as shown preferably, a gabeikopfförmiges component 4 are connected by means of retaining bolts.

The fork-head-shaped component 4 can be configured entirely as required as Doppelgabelvorbindungsglied, shown in Fip 2 and Fig. 3, or as a clevis hook.

Due to the structural design matched only in the load capacity, mutually intended combinations of the hangers are possible. 4 shows a suspension head for a trained on the modular principle load-strand-oriented two-strand chain suspension. Two connecting elements 3 are captive welded into the suspension member 1.
