TL;DR: In this paper, a rope drive device with a reciprocating wire arrangement function is described, which consists of a backup motor gearbox, a rope roller reducer, a winding roller, a reciprocation screw mechanism and an arrangement guide wheel set.
Abstract: The invention discloses a rope drive device with a reciprocating wire arrangement function. The rope drive device comprises a backup motor gearbox, a rope roller reducer, a winding roller, a reciprocating screw mechanism and an arrangement guide wheel set. A driving motor is connected with an output shaft of a backup motor and an input shaft of a planetary reducer through the backup motor gearbox, so that both the driving motor and the backup motor can drive the motor gearbox to move. The rope roller reducer transmits rotation of an output shaft of the planetary reducer to the winding roller according to a specified speed ratio, and a large torque is obtained. The winding roller is mounted at an output shaft of the rope roller reducer; a drive rope is wound on and unwound from the winding roller. A reciprocating screw of the reciprocating screw mechanism is connected with the winding roller through a gear and drives a nut slider mounted on the reciprocating screw, to reciprocate. The arrangement guide wheel set is fixedly connected with the screw slider and reciprocates with the screw slider to guide the drive rope being tightly wound on the winding roller in a reciprocating manner. The rope drive device allows winding and unwinding of the rope and allows the rope to be regularly and tightly wound.
