Internal tension maintaining device for main cable winding wire

The utility model belongs to the technical field of suspension bridge main cable winding wire construction, and particularly relates to a main cable winding wire internal tension maintaining device. A main cable wrapping wire internal tension maintaining device comprises a first clamping hoop, a pin shaft, a second clamping hoop and a bolt, the upper portion of the first clamping hoop is movably connected with the upper portion of the second clamping hoop through the pin shaft, and the lower portion of the first clamping hoop is fixedly connected with the lower portion of the second clamping hoop through the bolt. According to the utility model, through the pressing effect of the first clamping hoop and the second clamping hoop on the main cable wrapping wire, the end wrapping wire of the main cable is locked, so that the end wrapping wire and the main cable are kept relatively static, and enough friction force is formed to eliminate the torque generated by the internal tension of the wrapping wire on the mai
