Title:
WIRE-PULLING DEVICE FOR LAYING ELECTRIC CABLES
Document Type and Number:
WIPO Patent Application WO/2013/037075
Kind Code:
A3
Abstract:
The invention relates to a wire-pulling device, in particular for laying electric cables in a building, comprising a frame (16), a spool of a flexible elongate element (6a) wound into a coil, and means for unwinding said member and advancing same into a section of a duct of an electric facility. Said spool is mounted on a rotary drum (2) driven by a mechanism (13). Said drum (2) has a U-shaped section in which the flexible elongate member is arranged. Said flexible elongate member is fed into a rigid guide member arranged tangentially relative to the periphery of said rotary drum. Said drum (2) drives a set of guide rollers (19) arranged at the periphery thereof. Each roller has a central section (3) having a diameter that is larger than that of the side sections (4) thereof that surround same. The two side sections engage with the ends of the arms of the U while the central section contacts the flexible elongate member (6) arranged between the arms of said U, the contact of the central section having a tangential velocity higher than the velocity of the arms of said U with the flexible elongate member. The wire-pulling device includes an electronic device for controlling the motor for driving said drum.
