Target device for visual monitoring of displacement of inhaul cable

The utility model relates to a target device for inhaul cable displacement visual monitoring, the target device is installed on a bridge inhaul cable, the inhaul cable is provided with an inhaul cable clamp, and the target device comprises a spherical hinge clamp installed on the inhaul cable clamp, a spherical hinge clamped in the spherical hinge clamp and a plane visual target connected with the spherical hinge. According to the target device for inhaul cable displacement visual monitoring, the plane vision target is connected with the spherical hinge, and then the plane vision target is fixed to the inhaul cable through the spherical hinge clamp, so that the angle of the plane vision target and the angle of the inhaul cable are changed according to the spherical hinge, large-deflection-angle adjustment can be conveniently conducted on the direction of the plane vision target according to the observation direction of a camera, and the visual monitoring accuracy is improved. Therefore, the target pattern rec
