Abstract

Modular system for suspension (1) on a crane hook (2) or an attachment point or a lashing point, and a coupling hook (4) for use in such an arrangement.

Description

The invention relates to a modular system for suspension on a crane hook or an attachment point or a lashing point, and a coupling hook for use in such an arrangement.

The state of the art is that chain hangers or systems for chain suspension do not have any elements that can be coupled. Rather, chain hangers and their accessories are made to measure. A flexible use of the systems is therefore not or hardly possible.

Furthermore, it is the state of the art that several suspension rings and/or intermediate links and/or different hooks and/or adapters have to be used in order to achieve a coupling of different chain strands and/or hooks at all.

The Book of Revelation EP 3392525 A1 discloses a suspension ring which is designed in such a way that the carrying capacity as a function of the angle of inclination (an angle that the chain strands form with an imaginary vertical line) is easier for the user to recognize. Furthermore, it is shown here that chain links, i.e. the chain strands, are arranged directly on the suspension ring, which in turn causes a certain inflexibility.

The Book of Revelation DE 20 2019 101 470 U1 discloses a shortening hook with coupling connection for shortening sling chains in slings. The coupling connection is designed here as an eyelet to the detriment of flexibility. This prevents the coupling hook shown here from being used without the appropriate tools or intermediate components, which are attached to the eyelet would have to be able to couple to a crane hook, for example.

The pamphlet DE 696 22 88 1 T2 discloses a chain coupling arrangement with a closed ring member that can be coupled to a lifting device, such as a crane hook, and at least one chain coupling part with a shank portion that can be securely connected to the closed ring member and with a chain coupling portion that is coupled to at least one lifting chain can be.

Furthermore, the reference discloses US 2008/0315 604 A1 a sling system for connecting various loads to a lifting hook, comprising a small number of combinable sling units, each consisting of a number of pre-assembled parts. These units include at least one double sling unit and no more than two single sling units.

In the pamphlet DE 101 64 595 A1 discloses a hook with a fork head suitable for connecting a high-strength round steel chain, the fork tines of which delimit an insertion gap whose width is equal to 1.05 to 1.3 times the thickness of the links of the round steel chain and which is adapted to the inner width of the respective chain link to be connected Cross bolt is bridged, which is characterized in that the fork prongs of the hook outside the area of the insertion gap form an annular eyelet whose clear width (W2) is greater than the width (W1) of the insertion gap.

subject matter of the publication DE 101 49 340 A1 is a slinging device, in particular a shortening load hook, for chains, preferably round link chains. This lifeline has a hook and a shortening claw connected to the hook. This shortening claw divides the chain into a load strand and an associated chain bag, each of variable length.

In the pamphlet EP 0 105 022 A2 discloses a modular system, in particular for assembling load-lifting and/or lashing arrangements, consisting on the one hand of belts of different carrying capacities and on the other hand consisting of components that can be connected to these by means of coupling links, such as hooks, eyelets, shackles, fork heads, shortening claws, connection adapters or also belts, as well as Tensioning and/or control devices also having different carrying capacities, characterized in that the coupling members are designed as association elements for the belts and the components or belts or tensioning and/or control devices of the same carrying capacity.

The pamphlet EP 3 392 525 A1 discloses a suspension ring for multi-strand hangers, comprising two parallel, rectilinear legs which are connected to one another at their respective ends by arcuate connecting legs, the lower connecting leg being symmetrical to the longitudinal center line (MM) of the suspension ring and in the central region of its extension and in the two regions of its openings in each of the two legs, rounded in the shape of a segment of a circle, characterized in that the radii (r 1 , r 2 ) of the curves on the inside of the suspension ring are smaller than half the inside width (B) of the suspension ring, but larger than half the diameter (d) of the legs are, and the circular segment-shaped central area is connected at each of its ends to the circular segment-shaped junction area in the adjacent legs via a rectilinear intermediate section of the connecting leg, which is at an angle (δ) in the range of 50° to 75° to the longitudinal center line ie (MM) of the suspension ring (1) is engaged.

A disadvantage of the prior art is that for coupling the base segments, such as chains or belts, to the suspension ring or adapter Links are needed, especially when attaching four chain strands adapters are necessary because the suspension rings are designed from the prior art only for receiving a maximum of two chain strands. The adapters made for this are tailored to the suspension ring and are not intended for lengthening (coupling) the chain strands.

Presentation of the invention

It is therefore the object of the invention to eliminate the disadvantages of the prior art and to provide a system for suspension on a crane hook, an attachment point or a lashing point which is simple, flexible and modular in use and which allows basic elements to be provided which can be easily combined with one another . It should also be easy to assign the base elements according to different loads.

It is also the object of the invention to provide a coupling hook which can be used in the arrangement, but also independently of the manufacturer for coupling base segments, crane hooks and/or load hooks located on the base segments.

This problem is solved by the features listed in the claims.

According to various embodiments, the modular arrangement for suspension on a crane hook or an attachment point or a lashing point has the following components: a suspension ring, at least one coupling hook and at least one base segment, with a load hook being arranged at one end of the base segment. The suspension ring of the modular arrangement is designed in such a way that it has a non-positive connection with the crane hook or the attachment point or the lashing point and with the at least one Can form coupling hooks. According to various exemplary embodiments, the at least one coupling hook is designed in such a way that it can form a non-positive connection with the suspension ring, with the at least one base segment and/or with the load hook of the at least one base segment. The coupling hook has an underside and an upper side, the upper side according to the invention having a coupling element which is designed to create a connection to the crane hook or the attachment point or the lashing point and/or to the load hook of a base segment. The underside has a holder for receiving the base segments. According to various embodiments, a base segment is a chain segment and/or a belt segment and/or a cable segment. A receiver is, for example, a fork receiver for accommodating the chain segments or an eyelet for accommodating belt and/or cable segments.

The suspension ring is designed to accommodate two to four coupling hooks, with the suspension ring being designed according to the invention such that when two to four coupling hooks are used, an outer limit of a maximum permitted working angle of 60° is secured. According to various exemplary embodiments, the suspension ring has a teardrop shape in cross section with a semicircular underside, the semicircular underside having two opposite latching angles φ for maximum latching of the two to four coupling hooks. Furthermore, the suspension ring has a mounting point, for example a crane hook mounting point, which is arranged centrally on the opposite side of the underside.

According to various exemplary embodiments, the coupling element has a hook with a first securing element. The safety element, for example in the form of a snapper, is used for safety, so that the hook is prevented from slipping out. That The safety element or the snapper must be actively actuated to remove the coupling hook in order to release the connection of the coupling hook to the suspension ring or to the load hook.

The corresponding components (for example suspension ring, base segment, coupling hook) are preferably dimensioned according to different loads to be lifted, pulled and/or held. For example, there is a set consisting of a suspension ring, base chain segment and/or coupling hook for lighter loads, and a set (again consisting of a suspension ring, base chain segment and/or coupling hook) for heavier loads.

The different sets can be coded, for example by means of a color code, so that the different sets can be distinguished and assigned more quickly. For example, a first set for a lower load in the single strand up to 1000kg has the color purple. A second set, on the other hand, which can be used up to a load of 2000kg in a single strand, is green.

The underside of the coupling hook preferably has a shortener, for example a chain shortener. As a result, different lengths of chain strands, cable strands and/or belt strands can be set. For example, with a length of a base chain segment of 1 m, a chain strand length of 20 cm to 1 m can be set. According to various embodiments, the shortener can also have a securing element.

The object is also achieved by means of a coupling hook for use in an arrangement for suspension from a crane hook or an attachment point or a lashing point. According to various embodiments, the at least one coupling hook is designed in such a way that it can form a non-positive connection with the suspension ring, with the at least one base segment and/or with the load hook of the at least one base segment. Of the Coupling hook has an underside and an upper side, with the upper side having a coupling element which is designed in such a way as to create a connection to the crane hook or the attachment point or the lashing point and/or to the load hook of a base element, and the underside having a receiver for receiving Has base segments. The coupling hook according to the invention preferably also has a shortener.

According to various embodiments, a base segment is a chain segment, a cable segment, and/or a belt segment.

An advantage of the arrangement according to the invention and the coupling hook according to the invention is a simple connection of several basic chain segments to form a long chain strand. Only one suspension ring is required to attach this chain strand to the crane hook. The coupling hooks provide a secure and easy-to-make connection to chain strands and between the base chain segments themselves.

According to the invention, the various elements for lifting, holding and/or pulling objects with a crane or other attachment points or lashing points can thus be easily combined with one another. Special tools such as a hammer, screw block and/or mandrel punch are not required.

Likewise, pre-assembly by the manufacturer is not necessary. For example, it is not necessary to pre-assemble a suspension ring on the coupling hook or to pre-assemble a coupling point on a chain base segment. No manufacturer-specific measures need to be taken to ensure a secure connection. All elements are manufactured, sold and delivered separately. Furthermore, it is not necessary to search for suitable elements. Only a suspension ring, at least one coupling hook and base chain segments are required. A length of chain strands is thus freely selectable. Sorting of the elements of the arrangement according to the invention is only necessary for the load to be lifted. However, due to the color coding, a corresponding selection of the chain base segments, crane hooks and/or coupling hooks corresponding to the specific loads can easily be made.

It is also advantageous that no adapters or connecting links are required for coupling the base segments, such as chains or belts, to the suspension ring, especially when attaching four chain segments, no adapters are necessary because, in contrast to the suspension rings from the prior art, which are only designed to hold a maximum of two chain segments, the suspension ring presented here has more than two base segments. No adapters are required to accommodate more than two base segments. The coupling hook for connection to a suspension ring and/or for connection to a load hook of a base segment is designed in such a way that it is suitable for coupling or extending several base segments, with the extension being achieved by coupling the coupling element to the load hook of a first base segment and by means of coupling another base segment to the receiver of the coupling hook.
