AI Technical Summary
The existing multi-strand cable traction frame is inconvenient to transport after being fixed, and needs to be unfixed before it can be moved, which affects convenience. It is also inconvenient to disassemble and replace, increasing the labor intensity of the staff.
A multi-strand cable traction bracket was designed, comprising a base plate, bracket body, drive rod, drive wheel, pressure wheel, and motor. The motor drives the drive rod to rotate the drive wheel, achieving stable cable traction. The U-shaped plate and pressure wheel work together to reduce friction between the cable and the pressure wheel. Stainless steel bolts and small-pitch nuts are used to prevent loosening and increase the stability of the fixation.
It enables stable traction and transportation of multi-strand cables, reduces frictional damage to the cable surface, improves stability and convenience after fixing, and reduces the difficulty of disassembly and replacement.
