Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a heavy steel support structure (for lifting structures) in which a lobe hook projecting from a base body having at least partially circulating ropes is provided with a device. This invention relates to a suspension member made of cast steel.

Conventional Techniques In order to extract oil from the seabed, it is well known to create an artificial island under the sea and place a large steel container on the island. Such containers are equipped on land with all the equipment necessary for their respective requirements (e.g. polling, power generation, purification, water treatment, worker accommodation) and are equipped with almost three
It weighs up to ゜ooo t. Containers typically have 4 to 6 stops for suspending crane ropes.

These stop points are generally constructed as tubes, which are welded to a beam or support frame made of sheet metal.

Such structures are extremely expensive to manufacture, especially in the case of heavy containers. Such tubes have the following disadvantages: That is, pipes are placed across the container deck and, after the containers are unloaded, become in the way of another building in the Plan I form and therefore have to be burned down.

As an improvement, the stop points were made of cast steel with thick walls and rope hooks with profiles adapted to the crane rope. However, such a stop point is similar to the principle that one rope hook protrudes from each side of a thick beam-shaped base body. Since the rope hook part is located approximately in the center of the base body, and both ends of the rope hook part are connected to multiple intersection points of the container support member, a high bending moment is introduced into the container structure. .

OBJECT OF THE INVENTION It is an object of the invention to provide a suspension element which is inexpensively and concisely formed and which can be placed at one intersection of the support elements of a steel container in order to reduce bending moments. That's true.

Means for Solving the Problems The means of the present invention taken to solve the above-mentioned problems are:-
The base body is formed in a shell shape, and a rope hook part is arranged inside the base body, and the rope hook is located at the base of the part, and the rope hook as a rotation axis has a part axis line and a curve as a generatrix line. connected thereto is a rotating surface extending over at least 90 degrees in the range of the rope, the rotating surface extending tangentially from the rope hem with respect to the base and having an opening in the forward area of the rotating surface for receiving the crane rope; The goal is to make sure that you have the same.

According to an advantageous embodiment of the invention, the opening is approximately 1.1 to 3 times the width of the rope. By this, and because of the design of the inner surface of the shell-like base body, expensive maintenance time is saved, for example in crane ships, since the steel ropes are almost automatically released after lowering the steel support structure.

The respective type of profile or sheet can be welded to the side of the shell-like base body facing the steel support structure. In an advantageous manner, it is also possible to cast a connecting cross section on the basic body to which the steel support part is welded.

FIRST EMBODIMENT A rope hook part 2 having a lobe groove 5 is arranged inside a shell-like base body l. In the base 4, the rope hook as the axis of rotation extends over at least 90 degrees, and the surface of rotation 5 has a partial axis 6 and a curve 7 as the generatrix.

The rotating surface 5 extends tangentially from the rope groove 3 and has an opening 9 for receiving the crane rope 8, which opening is approximately 1.1 to 3 times the width 10 of the rope groove 3. . A connecting cross-section 11 is cast into the base body 1 to which the supporting mechanism parts shown in dash-dotted lines are welded.

Second Embodiment In the embodiment according to FIG. 3, the rope hook is arranged with its partial axis 6 in the horizontal direction. The basic body 1 extends up to the upper edge 12 of the steel support, shown in dash-dotted lines.

Third Embodiment In the embodiment according to FIG. 4, the rope hook is arranged with its partial axis 13 inclined to the horizontal, so that the crane rope is held vertically and at a distance above the stop point. A crane rope 8, which is not described here, can be used without a crane traverse to be placed and held.

Effects of the Invention The advantages obtained by the present invention are that one of the two conventional rope hooks can be omitted, and the rope hook can have the portion housed in a shell-like base; Furthermore, it is centrally located at the intersection of the restricted columns or walls of the steel support structure.

Furthermore, the suspension element according to the invention is compact and therefore able to accept large loads from rope pullers and steel support mechanisms. At the same time, the rope hook can sufficiently abut the crane rope around the part.
