La cinta incluye una pluralidad de elementos tensores de suspensión tales como alambres, simples o trenzados, de acero embutidos dentro de la cubierta de protección exterior, de manera similar a un conductor de corriente eléctrica, donde el conductor eléctrico está cubierto exteriormente por una camisa de aislamiento eléctrico. Debido a la cubierta de plástico no es fácil visualizar el estado o daños producidos en los alambres. Usually, steel cables have been used with or without any type of external protective covering. However, steel wire tapes or belts externally coated with a protective plastic cover are being introduced. The belt supports the tensile forces that the suspension tensioning element must withstand. The tape includes a plurality of suspension tensioning elements such as single or braided steel wires embedded within the outer protective cover, similar to an electrical current conductor, where the electrical conductor is externally covered by a jacket of Electrical isolation. Due to the plastic cover, it is not easy to visualize the condition or damage caused to the wires.

El conjunto es más flexible que los cables tradicionales y la cinta se puede acomodar a poleas de menor diámetro. Por otra parte, el contacto de la cinta con los diferentes componentes de la suspensión del elevador es más suave y silencioso. The electrical insulation jacket of the suspension tape protects the suspension tensioning elements and is made of an insulating plastic material such as polyurethane. The assembly is more flexible than traditional cables and the belt can accommodate smaller diameter pulleys. On the other hand, the contact of the belt with the different components of the lift suspension is smoother and quieter.

Suspension tensioning elements are a critical component in terms of safety. If a failure occurs or a breakage of these could lead to a fall of the elevator car, which would imply material and personal damage, to minimize this risk, a safety element is available in the system such as parachutes, brakes, wedging systems and others, and periodic inspections and replacements are carried out.
Por este motivo, en las instalaciones de elevación se utilizan unidades de comprobación que permiten comprobar el estado mecánico de los elementos tensores de suspensión que proporcionan criterios para sustituir los elementos tensores de suspensión en caso de deterioro o cambio periódico de los elementos de suspensión con el fin de evitar un potencial fallo de la instalación de elevación. For this reason, in lifting installations, test units are used to check the mechanical condition of the suspension tensioning elements, which provide criteria for replacing the suspension tensioning elements in the event of a deterioration or periodic change of the suspension elements in order to avoid a potential failure of the lifting system.
Una posibilidad para realizar la comprobación del estado de los elementos tensores de suspensión es mediante el establecimiento de un contacto eléctrico entre un elemento de contacto con los elementos tensores de suspensión. El elemento de contacto o bien accede a los alambres por los extremos libres o bien debe perforarse la camisa de aislamiento eléctrico, que envuelve de los elementos tensores de suspensión, para contactar con ellos. El elemento de contacto permite hacer pasar una corriente o señal eléctrica de prueba a través de los elementos tensores de suspensión. La señal eléctrica de prueba sirve para determinar el estado de los elementos tensores de suspensión. One possibility to check the state of the suspension tensioning elements is by establishing an electrical contact between a contact element with the suspension tensioning elements. The contact element either accesses the wires through the free ends or the electrical insulation jacket, which surrounds the suspension tensioning elements, must be pierced to contact them. The contact element enables a test current or electrical signal to be passed through the suspension tensioning elements. The electrical test signal is used to determine the condition of the suspension tensioning elements.

Asimismo, la operación del dispositivo conector eléctrico es sencillo. The electrical connector device is easy to mount on the suspension strap, as it requires the use of few tools, and the cost of manufacturing it is low. Also, the operation of the electrical connector device is simple.
El dispositivo conector eléctrico comprende una carcasa que presenta una ranura pasante por la que es insertadle la cinta de suspensión. La carcasa comprende un elemento excéntrico que se puede girar con respecto a su mismo eje y un elemento pisador distribuidor desplazable verticalmente con respecto a la ranura pasante, una pluralidad de elementos perforadores, en número igual al número de elementos tensores de suspensión, en contacto eléctrico con una unidad de evaluación. The electrical connector device comprises a housing having a through slot through which the suspension tape is inserted. The casing comprises an eccentric element that can be rotated with respect to its same axis and a distributor holding element movable vertically with respect to the through groove, a plurality of perforating elements, equal in number to the number of suspension tensioning elements, in electrical contact with an evaluation unit.
Los elementos perforadores están dispuestos uno junto al otro elemento perforador dentro de al menos un piano ortogonal al piano de la cinta de suspensión; es decir, los elementos perforadores están dispuestos paralelos entre sí dentro de un piano ortogonal o al tresbolillo distribuidos en al menos dos planos ortogonales al plano de la cinta de suspensión. The piercing elements are arranged side by side with the other piercing element within at least one plane orthogonal to the plane of the suspension tape; that is, the elements perforators are arranged parallel to each other within an orthogonal or staggered plane distributed in at least two planes orthogonal to the plane of the suspension tape.
Los elementos perforadores están configurados para traspasar la camisa de aislamiento eléctrico de la cinta de suspensión para establecer respectivamente una conexión eléctrica individual entre un elemento perforador y un elemento tensor de suspensión. Por consiguiente, el contacto eléctrico entre los elementos tensores de suspensión y los elementos de contacto eléctrico de perforación tiene lugar en dirección perpendicular al plano de la cinta de suspensión. The piercing elements are configured to penetrate the electrical insulating jacket of the suspension tape to respectively establish a single electrical connection between a piercing element and a suspension tensioning element. Consequently, the electrical contact between the suspension tensioning elements and the piercing electrical contact elements takes place in a direction perpendicular to the plane of the suspension tape.
El elemento pisador distribuidor es accíonable por medio del elemento excéntrico para que pueda realizar un movimiento vertical deslizante desde una posición de reposo hacia una posición de trabajo donde pisa la cinta de suspensión contra los elementos perforadores, que perforan la camisa de aislamiento eléctrico de la cinta de suspensión.

In the working position of the holding element, this element exerts a piercing clamping force on the suspension tape towards the piercing elements, so that the clamping force is maintained as long as the actuation of the eccentric element does not cease.
El elemento excéntrico del tipo leva, tornillo leva o similar, está montado en la carcasa con posibilidad de girar respecto a un eje longitudinal de esta leva. El elemento pisador está montado en la carcasa con posibilidad de desplazamiento vertical, según un eje perpendicular al eje longitudinal del elemento excéntrico. El elemento pisador presiona la cinta contra los elementos perforadores. En otra disposición el elemento pisador puede permanecer estático y la leva accionar a los elementos perforadores, de manera, que la cinta de suspensión es presionada por los elementos perforadores contra el elemento pisador. The eccentric element of the cam type, cam screw or the like, is mounted in the housing with the possibility of rotating with respect to a longitudinal axis of this cam. The pressing element is mounted in the casing with the possibility of vertical movement, along an axis perpendicular to the longitudinal axis of the eccentric element. The holding element presses the tape against the perforating elements. In another arrangement the holding element can remain static and the cam actuate the piercing elements, so that the suspension tape is pressed by the piercing elements against the holding element.
Por lo tanto, el elemento pisador de apriete presenta un movimiento regulado por el movimiento controlado del elemento excéntrico que pisa con presión uniforme y controlada sobre la cinta de soporte dispuesta en la ranura pasante de la carcasa para que los elementos perforadores penetren la camisa de aislamiento eléctrico de la cinta de suspensión. Ai cesar la actuación del elemento excéntrico, el elemento pisador puede retraerse desde la posición de trabajo hacia la posición de reposo o simplemente dejar de presionar la cinta, pudiéndose remover el contacto eléctrico establecido entre los elementos perforadores y los elementos tensores de suspensión. Therefore, the clamping plunger element has a movement regulated by the controlled movement of the eccentric element that steps with uniform and controlled pressure on the support tape arranged in the through groove of the casing so that the piercing elements penetrate the insulation jacket. electric suspension tape. When the actuation of the eccentric element ceases, the holding element can be retracted from the working position to the rest position or simply stop pressing the belt, being able to remove the electrical contact established between the piercing elements and the suspension tensioning elements.
El elemento excéntrico presenta una porción exterior libre a la carcasa y accesible desde el exterior de esta carcasa, de manera que, un operario puede manipular la porción exterior libre del elemento excéntrico para efectuar La regulación del paso en el avance del elemento excéntrico y, consecuentemente, del deslizamiento vertical del elemento pisador entre la posición de reposo y la posición de trabajo y viceversa.

Los elementos perforadores fienen unas dimensiones y tamaño que permite establecer una conexión eléctrica conductora regulada y controlada entre los elementos tensores de suspensión y la unidad de evaluación. Este contacto eléctrico establecido requiere que los elementos de perforación atraviesen la camisa de aislamiento eléctrico de la cinta de suspensión, evitando que los elementos perforadores se puedan desviar de la dirección de perforación prevista al perforar la camisa de aislamiento eléctrico, lo que podría impedir el contacto con los elementos tensores de suspensión y, además, los elementos perforadores también pudieran entrar en contacto con otros elementos tensores de suspensión contiguos estableciéndose un cortocircuito entre dos elementos tensores de suspensión adyacentes, no siendo deseable, o no entrar en contacto con ningún elemento tensor de suspensión al perforar la camisa de aisiamiento eléctrico de la cinta de suspensión. The piercing elements have dimensions and sizes that allow a regulated and controlled conductive electrical connection to be established between the suspension tensioning elements and the evaluation unit. This established electrical contact requires the piercing elements to pass through the electrical insulation jacket of the suspension tape, preventing the piercing elements from deviating from the intended piercing direction when piercing the electrical insulation jacket, which could prevent contact. with the suspension tensioning elements and, in addition, the piercing elements could also come into contact with other adjacent suspension tensioning elements, establishing a short circuit between two adjacent suspension tensioning elements, being undesirable, or not coming into contact with any tensioning element of suspension by piercing the electrical insulation jacket of the suspension tape.
