Abstract

A device for gripping elongated bodies, e.g. chimneys, and manipulating them, especially in a vertical position, comprising at least a pair of binding means, one end of which is adapted for detachable connection with the lower end of the manipulated body and the other end for connection with the manipulation means, in which the binding means are guided along the manipulated body by means of a ring-shaped stabilizing member, the position of which above the center of gravity of the manipulated body is ensured by stoppers mounted on the binding means or auxiliary binding means.

Description

OBŘÍZEK I

The invention relates to a device for gripping elongate bodies, for example chimneys, and their handling, in particular in a vertical position, comprising at least a pair of binding means, one end of which is adapted to detachably engage the lower end of the body to be manipulated.

According to the prior art, elongated bodies are handled by carrying out a tether over the center of gravity of the body for handling the body. After handling, it is necessary to disconnect the harness from the lifting mechanism, often at a considerable height. To disconnect the harness from the body or to attach the harness to the body, it is necessary to use high-lift assembly platforms or a fire ladder. A further disadvantage lies in the tension of the body from the tether, and moreover, the tear damages the surface finish of the body. Occasionally, the tether may be strangled from the body.

Furthermore, self-locking ties anchoring to the lower end of the body to be manipulated are known which, although they do not cause the body to be subjected to tensile stress, but otherwise have the aforementioned drawbacks. In addition, they cannot be used on bodies that have different protrusions, edges, etc.

These drawbacks are largely overcome by a device for gripping elongated bodies such as chimneys and handling them, in particular in a vertical position, comprising at least a pair of slings, the end of which is adapted to detachably engage the lower end of the body to be manipulated and according to the invention, characterized in that the binding means are guided along the manipulated body by means of a ring-shaped stabilizing member whose position above the center of gravity of the manipulated body is secured by tumblers mounted on the binding means or auxiliary binding means.

From the point of view of universal use, it is advantageous for the tumblers to be adjustable on the binding means. It is further preferred that the binding means and / or the auxiliary binding means are attached to a hinge, eg a crane traverse.

Finally, a preferred embodiment wherein the stabilizing, annular-shaped member is detachably provided.

The advantages of the invention are that there is no need to use a high-lift mobile platform or fire ladder, and consequently the cost of their operation, to strengthen the handling space, and to allow handling in confined spaces where it is not possible to position the means. It will increase the safety of work, speed up and facilitate the dismountability of the harness. Since the harness is attached to the lower part of the body, the tensile stress of the body is significantly reduced.

An exemplary embodiment of the invention is shown in the drawings, wherein Fig. 1 shows the body grip by means of hoisting mechanisms (not shown), Fig. 2 grip above the body and Fig. 3 grip the body in a horizontal position.

As an example of a chimney gripping device that greatly reduces the tensile stress of the body and ensures safe working, said construction is comprised of binding means 2 »which are attached at the bottom of the chimney 11 by occasional accessory 2 or permanent accessory 9. it is further guided through the stabilizing members 15 carried by the adjuster. The stabilizing hinge 5 is provided with an element 4 which ensures a secure bending of the binding means 2. For easy assembly and disassembly, the stabilizing hinge 5 is detachable.

Gripping and manipulation with the chimney proceed as follows. If the starting position of the chimney is vertical, the stabilizing member 5 is first assembled at the bottom of the chimney with the slinging means 3 provided with tumblers 6 threaded thereon. The tumblers are positioned so that the stabilizing member 5 is in the working position above the center of gravity of the chimney. The end of the binding means 3 is anchored, for example, to the foot of the chimney.

In case the starting position of the chimney is horizontal, the already assembled stabilizing member 5 is slid onto the chimney body, the tumblers are adjusted and the end of the binding means is anchored eg to the chimney base. Upon completion of the operation, the stabilizing member 5 is lowered to the bottom of the stack where it is dismantled.

The device according to the invention can be used for gripping and handling all kinds of elongated bodies, eg chemical columns and the like.
