A multi-rope cooperative control system testbed for an ultradeep mine hoist is
provided. A
hydraulic motor is mounted on a base and connected to a roller by couplings.
The roller is provided
with a wire rope connected to a cage. A tension sensor on the wire rope
detects the rope's tensile
forces and feedback a signal. A servo hydraulic cylinder is fixed on a hinge,
with the upper end
being connected to a headgear sheave bracket fixed on a linear guide rail. The
hinges and the linear
guide rail are connected to a steel structural bracket. The servo hydraulic
cylinder drives the
headgear sheave up and down via the headgear sheave bracket. A pressure sensor
is placed on the
headgear sheave bracket to detect pressure applied thereto. A spiral
instrument is fixed above the
cage located in the steel bracket to detect whether the cage is horizontal.
L'invention concerne un banc d'essai de système de commande coopérative à câbles multiples pour un treuil de mine ultra-profonde, relatif aux bancs d'essai de système de commande coopérative à câbles multiples pour des treuils. Un moteur hydraulique (1) est raccordé à un rouleau (2) au moyen d'un accouplement (14). Le rouleau (2) présente un câble métallique en acier (3). Le câble métallique en acier (3) est raccordé à une cage (13). Un capteur de tension (11) est placé sur le câble métallique en acier (3) afin de détecter la force de tension du câble métallique en acier et de renvoyer un signal. Un cylindre hydraulique asservi (6) est fixé sur une charnière (9) et l'extrémité supérieure est raccordée à un support (9) de molette. Une molette (8) est raccordée au support (9) de molette et le support (9) de molette est fixé sur un rail de guidage linéaire (7). La charnière (9) et le rail de guidage linéaire (7) sont raccordés à un support structurel en acier (4). Le cylindre hydraulique asservi (6) amène la molette (8) à se déplacer vers le haut et vers le bas au moyen du support (9) de molette. Le capteur de tension (11) est placé sur le câble métallique en acier (3) afin de détecter la force de tension du câble métallique en acier (3). Un capteur de pression (10) est placé sur le support (9) de molette pour détecter une pression appliquée sur la molette (8). Un instrument en spirale (12) est fixé au-dessus de la cage (13) pour détecter si la cage (13) est horizontale. La cage (13) est située dans le support structurel en acier (4). Le moteur hydraulique (1) est monté sur une base (15) de moteur. Dans le banc d'essai, la cage est levée de manière perpendiculaire à l'aide d'un mode de traînée du moteur hydraulique, rendant ainsi les opérations simples et aidant à réaliser la maintenance.
