This invention discloses a drawing device for steel wire rope preparation, relating to the technical field of steel wire rope drawing devices. It includes a worktable, with a drive mechanism movably connected to the lower part of the worktable's inner cavity. Two left-right distributed support frames are fixedly connected above the drive mechanism. A pressing mechanism is movably connected inside each support frame. The drive mechanism includes a first motor, with its right side fixedly connected to the left side of the worktable. This steel wire rope drawing device, through the cooperation of a first motor, a bidirectional threaded rod, a sliding plate, an upper die, a lower die, a hydraulic rod, a support plate, a second motor, a roller, and a take-up roller, achieves both drawing and take-up of the steel wire rope using a drawing die. The first motor drives the bidirectional threaded rod to rotate, causing the sliding plate to move the upper support frames and the pressing mechanism in opposite directions, thus drawing the steel wire rope. The second motor drives the take-up roller to rewind the steel wire rope, realizing the drawing and rewinding of the steel wire rope using a drawing die.

The present invention discloses a system and method for detecting the effective pre-tightening force of a cable clamp screw of a long-span suspension bridge. A nut clamp is sleeved on the cable clamp nut of the suspension bridge cable clamp, and a sensor for detecting the contact state of the cable clamp nut is provided on the nut clamp; a hydraulic screw puller can be connected to the exposed section of the cable clamp screw of the suspension bridge cable clamp and abut against the upper cable clamp surface of the suspension bridge cable clamp. The present invention can apply tension to the exposed section of the cable clamp screw through the hydraulic screw puller to achieve pulling of the cable clamp screw. The detection result of the sensor provided on the nut clamp can be used to determine whether the cable clamp nut is separated from the upper cable clamp surface, so as to determine the timing of the cable clamp nut being separated from the upper cable clamp surface. When it is determined that the cable clamp nut is separated from the upper cable clamp surface, the effective pre-tightening force value of the suspension bridge cable clamp is determined according to the tension value applied by the hydraulic screw puller at this time. The present invention is low in cost and does not damage the screw, and has obvious technical advantages over similar screw pre-tightening force detection methods.
