Description

DETAILED DESCRIPTION OF THE INVENTION Areas of Use of the Invention The invention provides a method for punching plastic and elastic material articles, especially steel cable conveyor belts, with holes, longitudinal cracks, notches, transverse cracks, rope external cracks, damaged ropes. It is used in rejuvenation and repair with the aid of hot vulcanization as well as cold repair (cold vulcanization), especially of carcass damage, such as edge damage, corrosion, etc.

Characteristics of the known technical solution Methods for refurbishing and repairing steel cable conveyor belts are already known. These methods use a rope cut or separated from a belt piece with a fully vulcanized rubber coating. However, these methods did not guarantee effective and quality-ensuring regeneration or repair of damaged carcass or rope. The known methods are extremely difficult to control, expensive to work with, and lack a good uniform bond with the carcass or rope that is being repaired or regenerated, which makes it difficult to control steel cable conveyor belts. Reuse may even lead to partial repair or refurbishment points, especially in the carcass or even slack in the rope. Therefore, a high service value of the refurbished or repaired steel cable conveyor belt cannot necessarily be achieved.

OBJECTS OF THE INVENTION The object of the invention is to achieve high value-of-use properties of steel cable conveyor belts in a cost-effective manner by remanufacturing and/or repair.

DETAILED DESCRIPTION OF THE INVENTION It is an object of the invention to develop a rope and a method for refurbishing and repairing plastic and elastic material articles, in particular steel cable conveyor belts, which method comprises a rope and/or a rope. Hot vulcanization and/or cold vulcanization during tight bonding of the strip and/or plastic and/or inserted refurbishment or repair pieces of elastic material, e.g. rubber, with the damaged carcass and belt joint. Interval vulcanization ensures regeneration and repair. According to the present invention, this problem is solved as follows. That is, ropes for remanufacturing and repairing articles of plastic and elastic material, preferably steel cable conveyor belts, are made up of a number of strands, which are twisted into strands, and the strands are made into textiles or similar. are twisted or wrapped around each other with materials that are themselves surrounded by an unvulcanized rubber coating or an elastic and/or plastic material coating, and which have plastic properties in the envelope or coating, or both. Alternatively, the elastic material contains a metal adhesive.

Another arrangement according to the invention has the strands loosely twisted or wrapped around them.

Furthermore, according to the invention, plastic or elastic material metal adhesives are preferably used, for example cobalt-based and/or R
It is made of known adhesives such as FS type.

According to the invention, the adhesive is a plastic or elastic woven metal adhesive or a rubber woven metal adhesive.

Furthermore, according to the invention, the adhesive is a plastic or elastic woven adhesive.

Additionally, according to the invention, the rope is a cable-stranded rope, the strands and/or legs of which are twisted or wrapped around with textiles or similar materials. Furthermore, according to the invention, the number of strands and/or legs and their embodiments are preferably three, with or without a core, as appropriate.

The method according to the invention comprises replacing the broken rope with a not fully vulcanized rubber mixture or a not fully cured plastic or elastic material mixture and a rope with a twisted section or envelope around the woven or similar material. or a woven or similar twisted section or a spout having only an envelope is inserted and covered with unvulcanized rubber or a non-fully cured plastic or elastic material, as is known, and thus Fully vulcanized or hardened unvulcanized rubber mixtures or unhardened plastic or elastic materials applied to the sheathing of the rope or woven envelopes of the rope or both plastic or elastic materials metal adhesives or rubber metals. Adhesive or plastic or elastic material woven metal adhesive or rubber woven metal adhesive or plastic or elastic material woven adhesive or rubber woven adhesive.

Furthermore, according to the invention, a rope strip consisting of a suitable number of ropes coated or extruded with plastic and/or elastic material that is not completely cured or with unvulcanized rubber is inserted into the conveyor belt.

Moreover, the advantages of the rope according to the invention are not only based on the possibility of durable, extremely simple and favorable connection of elastic materials such as plastic and/or rubber to this rope, but also because this rope It has properties of particular importance for refurbishing and repairing on the basis of The rope according to the invention assumes a straight and stable position even under slight tension and therefore preferably can be positioned and fixed with great precision.

With the rope according to the invention, vibrations due to collisions are damped in a shorter time than with conventional ropes.

This results in relatively low loading of the joints of plastic and/or elastic material, such as rubber, on the rope. The slight elasticity of the rope according to the invention significantly reduces the tendency of the rope end at the refurbishment or repair site to become detached from the end of plastic and/or elastic materials, such as rubber joints. The so-called "finger effect" also disappears to the greatest extent. The rope according to the invention has an extremely good ability to absorb energy.

The rope according to the invention has advantages over hitherto known rope structures that these structures do not have collectively.

The rope according to the invention is particularly useful for refurbished or repaired conveyor belts in contrast to known rope constructions due to its excellent bonding properties to the carcass or conveyor belt and therefore less tendency to mechanically peel away from belt joints. This yields advantages that give it a value in use that is almost equivalent to a new belt.

All known steel cable conveyor belt structures can be refurbished or repaired with the ropes or methods of the present invention.

The present invention will be described in detail below with reference to embodiments of the accompanying drawings.

As shown in Figure 1, a three-strand rope is a three-strand rope in which each strand is surrounded by a woven or similar surrounding twisted section or envelope, and the surrounding twisted section or envelope is bonded. can be provided with an agent.

FIG. 2 shows the chemistry of a sheathing 3 made of plastic and/or elastic material, e.g. Figure 1 schematically shows the joints.

This bonding action is achieved in the surrounding twisted part or envelope 2 and/or the covering part 3 by means of a chemical adhesive that penetrates through the surrounding twisted part or envelope 2.

As shown in FIG. 3, the rope according to FIG. Adhesive can be added to the section or envelope 2 or the covering 3 during chemical bonding to the strand 1.

After twisting the strands into a rope, a fixed and durable mechanical bonding effect of the part or envelope 2 already twisted around the rope is also achieved, and the bonding action itself is not applied to the layer 2. ) is still protected even if it is damaged.

This applies equally to the twisting of the strand 1 to the leg and the leg to the rope.

The pull-twisted rope shown in Figure 4 is particularly flexible and has significant surface cracks. 1st, 2nd
Alternatively, it can have an adhesive in the covering part 3 and/or in the surrounding twisted part or envelope part 2, similar to the rope shown and described in FIG.

As shown in FIG. 5, a suitable number of ropes, similar to the ropes of FIG. The twisted part or envelope part (
2) and/or an adhesive can be added for chemical bonding to the strand 1 in the covering 3.

Damaged or rusted rope ends must be removed during hot vulcanization refurbishment or repair. The refurbished or repaired area is sufficiently cut out so that no sharp edges occur. Recesses and edges must be sufficiently roughened and dirt and roughness dust removed.

The initial rope or ropes with defects are replaced by a new rope or ropes according to FIGS. 1-5.

The belt piece to be refurbished or repaired is covered with unvulcanized rubber over, between and under the rope or ropes, if necessary, and is then vulcanized in a known manner.

For example, known cobalt-based and/or RFS-based adhesives can be used.
