Abstract
Synchronization assembly and plant for laying cables such as electric conductors, optical fibers, ropes or suchlike. The machines of the assembly and plant are distinct and independent with respect to each other and each includes unwinding members having at least a pair of capstans to unwind the cables, and corresponding traction/collection members having at least a pair of capstans to wind the cables fed from the relative unwinding members. The synchronization assembly and plant includes automatic adjustment members that adjust the speed of rotation of the capstans of at least two unwinding members or two traction/collection members of the laying machines, so as to maintain the winding/unwinding speed of the cables stretched by each machine substantially equal.
Claims4
A plant for installing cables on pylons, said plant comprising:
- a plurality of machines which are distinct and independent with respect to each other, each of said machines including an unwinding member having a pair of first capstans able to unwind the cables and a corresponding collection member having a pair of second capstans able to wind the cables, said first capstans of said machines forming a first set and said second capstans of said machines forming a second set, said unwinding members and said collection members being positioned on opposite sides with respect to the pylons on which the cables are hung;
- a plurality of synchronization devices able to adjust relative speed of rotation of capstans of only one of the first and second sets of the first and second capstans of said machines, wherein a relative speed of cable-laying of said cables associated with said machines is substantially equal, each of said synchronization devices having a plurality of control cards with the control cards being connected to position detection elements associated with capstans of said only one of the first and second sets of the first and second capstans of said machines, all of the control cards of each of said machines being connected by connections to one another;
- and
- a control panel connected to each of said plurality of synchronization devices for an operator to control said capstans of all machines, wherein a single machine may be stopped while all others continue to operate;
- wherein an operator performs programming, control, rectification and verification operations during the unwinding of the cables associated with all of the plurality of machines.
