Embodiment
Below in conjunction with the accompanying drawings and utility model is described further specific embodiment：
A kind of as shown in figure 1, arch bridge cable-hoisting construction stayed knotting method knotted rope tensioning equipment.
Structure composition and connection
With reference to accompanying drawing 1-3, the application utility model is made up of three parts altogether, is respectively：1- fixed chute pedestals, 2- are slided
Carry-over bar, 3- drive gear sets.
The thin portion of each several part is formed
（1）Fixed chute pedestal.Fixed chute is formed by high strength low-carbon steel one-step casting, and construction includes 1-1 pedestals bottom
Plate, 1-2 floor chutes, 1-3 pedestal risers, 1-4 roof chutes, 1-5 anchor cable fixing end connection rings, 1-6 stop bit blocks.
（2）Slide tensioning rack.Sliding rack is formed by high strength low-carbon steel one-step casting, and construction includes 2-1 slide teeths
Bar, 2-2 anchor cables mobile terminal connection ring, 2-3 stop rods.
（3）Drive gear set.Construction includes 3-1 fixing bearings, 3-2 ball bearings, 3-3 driving gears, 3-4 driven tooths
