Description

Technical field

This technical solution relates to a device for processing spent steel-aluminum ropes, in particular for the purpose of their further material recovery.

BACKGROUND OF THE INVENTION

Currently, aluminum-aluminum ropes, an aluminum sheath, wound and serving as a conductor, and an inner steel core, usually a steel wire of high mechanical strength, are used as electrical wires in a large line of all voltages consisting of aluminum wires for outdoor electrical scale. so-called Alpha ropes. In view of the considerable expansion of these ropes, the subsequent disposal of old and used steel-aluminum ropes is a serious problem, since for their further processing, usually by metallurgical processes, in order to reuse particularly conductive aluminum, it is necessary to separate the aluminum sheath from the inner steel tube. If currently being processed, the spent steel-aluminum ropes are usually cut into pieces of greater length, thereby releasing the winding of the aluminum sheath, and the aluminum sheath is then essentially unraveled by hand. Obviously, such a process is very lengthy and physically strenuous, hindering the processing of the spent ropes to a greater extent, which, on the one hand, results in considerable material losses, in particular aluminum, and, on the other hand, difficulty for various distribution organizations and manufacturing companies to dispose of them.

The essence of the technical solution

These drawbacks of the prior art are largely overcome by the treatment equipment used

aluminum-aluminum wire ropes consisting of an inner steel core and an outer wound aluminum sheath, according to the present invention, characterized in that it consists of at least one driven winding drum mounted on a support frame in which at least one bore of the steel core of the aluminum aluminum wire .

The device according to the present invention allows, after unraveling the end of the aluminum-aluminum rope, to pass its steel core through the pull-through opening and after its attachment to the driven winding drum and start its drive quickly and easily pulling the aluminum sheath from the aluminum-aluminum wire. on the winding drum and the aluminum sheath is collected in front of the bore. This device thus resolves the basic phase of processing spent steel-aluminum ropes by separating their aluminum sheath from the inner steel core. The advantage of the device according to this technical solution is at the same time its simple construction, low purchase price and usability for all types and diameters of steel-aluminum or similar ropes.

Preferably, the winding drum is arranged vertically on the support frame and is provided at its lower end with which it is received in the support frame with a disc in which the anchoring holes of the coiled steel core of the aluminum-aluminum rope are formed. horizontally in the direction of the tangent to the surface of the winding drum.

With a plurality of boreholes and possibly also winding drums, under the appropriate conditions of the device according to the invention, several steel-aluminum ropes can be used simultaneously, which of course results in an increase in labor productivity.

BRIEF DESCRIPTION OF THE DRAWINGS FIG

The technical solution is closer to a specific embodiment of spent steel-aluminum ropes of the solution, in which Fig. 1 shows this device in front view, Fig. 2 shows this device in side view and Fig. 3 shows this device in plan view.

Example of technical solution

The apparatus for processing spent steel-aluminum ropes, according to FIGS. 1 to 3, consists of a support frame 1 with a face plate 2, on which a driven winding drum 3 is mounted vertically, provided with a disc at its lower end. 4 with four anchoring holes 5 for attaching the end of the steel tube in the drawing of a steel-aluminum wire rope (not shown) pre-drawn through the bore 6 formed in the front plate 2 of the support frame 1 horizontally in the tangent direction to the winding drum 3. The support frame 1 is solved by an electric motor with respective gears, in this particular embodiment 60 revolutions of the winding drum 6 per minute are achieved. At the same time, the drive also allows the winding drum 3 to reverse, which is important in some cases for loosening the steel-core of the aluminum-aluminum rope on the winding drum 3 during its removal. The diameter of the winding drum 3 is 300 mm, the diameter of the bore 6 is Hm. In this design, the device allows processing of aluminum-aluminum ropes up to 30 meters, possibly longer, depending on the type of rope and its quality.

The equipment according to this technical solution can be used especially in metal waste processing organizations, eventually also in the operators of electricity distribution, in larger industrial enterprises and the like.
