CS259057B1 - Flux for brazing oeazed blanket sheets - Google Patents

Abstract

The invention falls within the field of recording technology. It concerns the problem of soldering printed circuit boards, with the flux composition being designed to achieve very high-quality soldering and the flux residues do not need to be removed after the soldered parts are soldered. The essence of the solution is the flux composition consisting of 5-20.,i by weight of rosin, 1-4 ·» by weight of oteric acid or stearin, 0.1-1 ,i by weight of diethylamine hydrochloride, 1-9 ,i by weight of hydroxybenzoic acid and 66-92.9 /» by weight of ethyl alcohol or isopropyl alcohol.

Description

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 for detachable connection and the lower end of the body to be manipulated; . ,.

According to the prior art, elongate bodies are handled in such a way that; above the center of gravity of the body performs a tie, for which the body is manipulated. 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 · attach the harness to the body; It is necessary to use forklift assembly platforms, eventually fire ladder · i Another disadvantage lies in the stress of the body from the harness in tension, also the harness damages the surface finish of the body. Occasionally, the harness may be strangled into the body.

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

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

In terms of universal use is. it is advantageous for the tumblers to be adjustable on the binding means. Furthermore, it is preferable 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 brigade, as well as the cost of operating it, to strengthen the handling space, and to allow handling in confined spaces where no

-2 it is possible to ensure the establishment of these funds. It will increase work safety, speed up and facilitate the dismountability of the harness. Since the tie is attached to the lower part of the body, the tensile stress of the body is greatly reduced.

An exemplary embodiment of the invention is shown in the drawings, wherein FIG. 2) the grip above the body and FIG. 3 the grip of the body in a horizontal position.

As an example, a chimney gripping device that greatly reduces the tensile stress of the body and ensures a safe work, said construction consisting of binding means 3, which are attached at the bottom of the chimney 2 by occasional accessories 2, or permanent accessories 9. The stabilizing hinge 5 is provided with an element 4 which ensures a secure bending of the binding means 3. For easy assembly and disassembly, the stabilizing hinge 5 is detachable.

UGoping and handling the chimney is as follows. In case the starting position of the chimney is vertical, the stabilizing member 5 is first assembled at the foot of the chimney with the slinging means 3 provided with tumblers 6. The tumblers b are set so that the stabilizing member 5 is in 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.

If the training position of the chimney is horizontal, then the already assembled stabilizing member 5 is slid onto the chimney body, the tumblers 6 are adjusted and the end of the binding means 3 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 manipulating all the drones of elongated bodies such as chemical columns etc.
