[0003] Chinese patent CN202466415U discloses a dorsal cable tail puller, the puller is equipped with a balance long shaft and a balance weight, but the weight of the cable head clamp for the dragged strands is generally 200~500kg, because the entire suspension system It is flexible, the tension and relaxation of the traction rope will still cause the swing of the strands and deviate from the traction line and the vibration of the whole wire rope, and it will also lead to the swing of the strands, which is not good for the strands

Embodiment Construction
[0014] The connection method between the puller and the traction rope is that the traction rope is connected with the wedge-shaped joint of the wire rope through the front and rear shuttle tubes, the head clamp of the pulled cable is connected with the traction ear through the pin shaft, and the hoist pulls the wire rope to drive the puller on both sides of the suspension bridge. back and forth between.
[0015] The heads of the front shuttle 3 and the rear shuttle 4 are designed to be tapered so that the puller can smoothly pass through the paired pulley groove of the guide wheel group; the upper balance adjustment screw shaft 5 and the upper balance weight 6 are on the right side The eccentric weight balance of the connecting plate and other parts is adjusted by adjusting the screw rod to adjust the left and right balance; the center of the traction ear 7 and the shuttle are designed to be on the same center line, so that the drawn strands and the traction rope of the winch a...

The invention provides a puller for paying-off and towing a rope strand of a suspension bridge. The puller comprises a wedged connector connecting frame 1, a front connecting rod 11, a back connecting rod 12 and a horizontal connecting rod 13, which are connected through pin shafts and form a triangular rod frame of the puller. A traction rope 16 is fixed on a steel wire rope wedged connector 2 of the puller through a front shuttle pipe 3 and a back shuttle pipe 4; the rope head of a towed rope strand 15 is connected with a traction lug 7 through a rope head clamp 14; and an upper balance adjusting lead screw shaft 5 of the puller is additionally provided with a lower balance counterweight 8 and a lower balance adjusting lead screw shaft 9 connected by a lower balance adjusting lead screw shaft 10. The puller is additionally provided with the lower balance counterweight 8 and the lower balance adjusting lead screw shaft 9 for ballasting and balancing a traction system, so that the puller and the rope strand are stably operated.
Description
technical field [0001] The invention relates to a cable-laying and traction device for a suspension bridge, which belongs to the field of design and manufacture of bridge construction equipment. Background technique [0002] Suspension bridge, also known as suspension bridge, refers to a bridge whose main load-bearing member of the superstructure is the cable suspended by the tower and anchored on both banks (or at both ends of the bridge). The main load-bearing component of the suspension bridge is the suspension cable. The suspension cable is composed of many cable strands. Each strand is produced by the production factory and wound on the cable tray, and then transported to the construction site to be released and erected. It is suspended and anchored by the cable tower. On both sides of the bank, the rope erection process is to put one end of the main cable into the puller, and the puller is connected to the traction wire rope of the hoist fixed on both sides of the bank...
