Description

Cable para aparatos elevadores.Cable for lifting devices.

La presente invención, como su propio título indica se refiere a un cable para ascensores y montacargas, que se unen por una parte a la cabina y por el otro extremo a un contrapeso, pasando por una polea superior de accionamiento.The present invention, as its own title indicates refers to a cable for elevators and forklifts, which they join the cabin on the one hand and on the other end a counterweight, going through a top drive pulley.

Los cables de ascensores o montacargas normalmente suelen estar constituidos por un alma interior de acero o de fibras orgánicas naturales, alrededor de la cual se disponen una serie de paquetes de cables, habitualmente también de acero. Una solución mixta, con un alma central separada de unos paquetes envolventes por una capa aislante está representada en el documento EPO444245.Elevator or forklift cables usually they consist of an inner soul of steel or of natural organic fibers, around which they are arranged a series of cable packages, usually also of steel. A mixed solution, with a central soul separated from packages envelopes by an insulating layer is represented in the document EPO444245.

El documento EP0633350 describe un cable formado por un alma central con una serie de paquetes de cables de acero, que está rodeada por una serie de paquetes de cables de los cuales los filamentos exteriores son metálicos y rodean un alma central de mayor diámetro formada por un material sintético, como puede ser polietileno, polipropileno, poliamida u otras sustancias análogas.EP0633350 describes a formed cable by a central soul with a series of steel cable packages, which is surrounded by a series of cable packages of which the outer filaments are metallic and surround a central soul of larger diameter formed by a synthetic material, such as polyethylene, polypropylene, polyamide or other substances analogous

El documento ES2141851 describe un cable que comprende un paquete central de cables, rodeado de una camisa envolvente, entorno a la cual se sitúan un segundo grupo de cables, así mismo protegido exteriormente por otra envolvente sintética. Los cables son en ambos casos, tanto en la capa interior como exterior, de aramida y la envolvente de los cables interiores es de poliéster, plástico o silicona, mientras que la del envolvente externa es de poliuretano.Document ES2141851 describes a cable that It comprises a central cable package, surrounded by a jacket envelope, around which a second group of cables are located, likewise protected externally by another synthetic envelope. The cables are in both cases, both in the inner layer and exterior, aramid and the inner cable sheath is polyester, plastic or silicone, while the envelope External is polyurethane.

El documento DE1904468 se refiere a un procedimiento para fabricación de un cable de hilos con un revestimiento de material sintético, que protege el cable de la humedad y en consecuencia de la oxidación; entre los cables metálicos se introducen hilos de material sintético que se funden y fusionan con el revestimiento final embebiendo así perfectamente los cables metálicos interiores.Document DE1904468 refers to a procedure for manufacturing a wire cable with a Synthetic material lining, which protects the cable from the moisture and as a consequence of oxidation; between the wires metallic synthetic yarns are introduced that melt and merge with the final coating thus embedding perfectly the inner metal cables.

Dado que un fallo en los cables de los que pende la cabina del ascensor podría tener consecuencias funestas para las personas que lo emplean, los coeficientes de seguridad que se exigen a los cables de ascensores y montacargas son muy elevados. En España se requiere que los cables de los ascensores sean de acero y que la relación entre el diámetro de las poleas y el diámetro de los cables sea cómo mínimo de 40. El motivo de éstas generosas poleas es el de minimizar la fatiga y el desgaste de los cables de acero, en su continuo vaivén sobre las poleas.Since a fault in the cables that hangs the elevator car could have dire consequences for people who use it, the safety coefficients that are They require lifts and forklift cables are very high. In Spain, the elevator cables are required to be steel and that the relationship between the diameter of the pulleys and the cable diameter is at least 40. The reason for these generous pulleys is to minimize fatigue and wear of Steel cables, in their continuous swing on the pulleys.

Ahora bien, si lo que se desea es una maquinaria de ascensor que ocupe un menor volumen, particularmente en altura, se requiere reducir el diámetro de las poleas y en consecuencia el diámetro del cable que soporta la cabina, para ello se recurre al empleo de cables de filamentos de acero perlítico, similares a los empleados en el refuerzo de cubiertas de los neumáticos automóviles, que tienen un diámetro muy reducido y son particularmente flexibles y resistentes a la fatiga con cargas alternadas.Now, if what you want is a machinery of elevator that occupies a smaller volume, particularly in height, it is required to reduce the diameter of the pulleys and consequently the diameter of the cable that supports the cabin, for this purpose the use of perlitic steel filament cables, similar to used in the reinforcement of tire covers cars, which have a very small diameter and are particularly flexible and resistant to fatigue with loads alternated

La solución que se propone en la presente invención consiste en un cable que presenta un haz de cables enrollados, en el que un cable central o interior presenta mayor grosor que los situados periféricamente entorno a éste. Cada uno de estos cables está a su vez formado por un número constante de filamentos de acero perlítico enrollados, presentando mayor sección los filamentos que componen el cable central o interior. La cuerda así formada se embebe en poliuretano formando una sección circular constante.The solution proposed here invention consists of a cable that has a bundle of cables coiled, in which a central or inner cable has greater thickness than those located peripherally around it. Each one of these cables are in turn formed by a constant number of Perlithic steel filaments rolled, presenting greater section the filaments that make up the central or inner cable. Rope so formed it is embedded in polyurethane forming a circular section constant.

Estos paquetes de filamentos que forman cada uno de los componentes del cable principal son filamentos muy delgados y por tanto flexibles de acero perlítico de alta resistencia mecánica,These filament packages that make up each of the main cable components are very thin filaments and therefore flexible high strength perlithic steel mechanics,

Según una importante característica de la presente invención, el sentido de enrollamiento del haz de cables principales es opuesta a la de enrollamiento de los filamentos que componen cada uno de estos cables.According to an important characteristic of the present invention, the direction of winding of the cable bundle main is opposite to the winding of the filaments that make up each of these cables.

El haz de cables que lo estructura está formado por un cable interior y seis cables enrollados entorno a este central y el paso del enrollamiento de este haz está comprendido entre 25 y 55 mm.The cable harness that structures it is formed by an inner cable and six coiled cables around this center and the winding step of this beam is comprised between 25 and 55 mm.

Tanto el cable central como los enrollados entorno a él están formados por un número igual de filamentos de acero perlítico, comprendido entre 15 y 25.Both the central and the coiled cables around it are formed by an equal number of filaments of Perlithic steel, between 15 and 25.

Con las especificaciones citadas y adecuando el paso de enrollamiento de los filamentos del torón o cable central y de los filamentos del los cables o torones exteriores, al tiempo que se adecua también el paso del enrollamiento de los cables exteriores sobre el cable central y efectuando el enrollamiento del cable central con respecto a los periféricos en sentidos opuestos, se consigue reducir el diámetro de la sección de un cable convencional de este tipo, revestidos de un material sintético entre un 35 y un 40%, manteniendo no obstante la carga de rotura adecuada a las normas sobre aparatos elevadores.With the specifications cited and adapting the winding step of the strands of the toron or central cable and of the strands of the outer wires or strands at the same time that the cable winding step is also adapted outer on the central cable and winding the central cable with respect to peripherals in opposite directions, it is possible to reduce the diameter of the section of a cable conventional of this type, coated with a synthetic material between 35 and 40%, while maintaining the adequate breaking load to the rules on lifting devices.
