Step 6：End carriage side fining twisted steel nuts and washers is screwed on, girder, urging portion are installed.
The invention has the advantages that：The present invention provides a kind of main rope of suspension bridge thrustor herein by improving, described
Main push-towing rope thrustor includes girder, and the two ends of girder are respectively arranged with one group of preceding thrustor, rear thrustor；The two ends of girder
Head is respectively arranged with one group of screw thread bridle iron；Fining twisted steel one end pass through after screw thread bridle iron by fining twisted steel nut and
Packing ring screws on fixation, and the other end is fixed by the screw-thread steel support base on girder；Wherein, fining twisted steel is through preceding pushing tow dress
Put, rear thrustor, and preceding thrustor, rear thrustor determined by the fining twisted steel nut on fining twisted steel
Position；Jack is provided between preceding thrustor, rear thrustor, the wirerope-winding between preceding thrustor and main push-towing rope.This
After invention is improved, the pushing tow work of the main push-towing rope adjusting apparatus passes through wirerope-winding on preceding thrustor and main push-towing rope, empty
Heart pushing tow jack realizes pushing tow；During pushing tow, rear thrustor is positioned by fining twisted steel nut first, manually behaviour
Make jack, promote the single pushing tow haul distance of main push-towing rope movement respective support numbering, then will by fining twisted steel nut
Preceding thrustor positioning, promotes equal haul distance, this circulates this flow, until main push-towing rope is pushed into target by rear thrustor
Position.
