Prestressed steel strand unbounded tendon rope threading machine
The invention relates to a prestressed steel strand unbounded tendon rope threading machine. The prestressed steel strand unbounded tendon rope threading machine comprises tire groups, a transmission part, a motor, a variable-frequency control box, a guide device and an installation frame; the tire groups are divided into n groups, wherein n is greater than or equal to 1 and less than or equal to 6; the transmission part comprises a gear set, a chain wheel group formed by chain wheels and a chain, a rotating shaft and a reducer of the rotating shaft; tires of the tire groups are respectively installed on an installation frame upper frame and an installation frame undercarriage; under a working state, motor drives the tires which are respectively installed on the installation frame upper frame and the installation frame undercarriage to rotate relative to each other by virtue of the transmission of the reducer and the gear and the chain wheel, a single unbounded steel strand passes through a slit between two relatively rotating tires installed on the installation frame upper frame and the installation frame undercarriage in a squeezing manner by virtue of the guide device, the single unbounded steel strand is pushed by the two relatively rotating tires to move forwards by virtue of squeezing friction force, and a rope threading process of the steel strand from a bridge deck to a rope tower and then to the bridge deck can be realized; the rope threading machine can greatly alleviate the labor intensity of operators and improve the rope suspension construction efficiency.
