Direction-changing anchorage cable

The utility model discloses a novel turning anchor, comprising a pallet and an anchor ring; corresponding positions of the anchor ring and the pallet are provided with through holes; the through hole of the anchor ring is a conical hole with small interior and large exterior; the internal wall of the conical hole is provided with a wedge-shaped clamping tablet; the through hole position between the pallet and the anchor ring is provided with a hollow concave anchor ring base; the end of the anchor ring is matched with the spherical surface of the concave anchor ring base; the bottom surface of the concave anchor ring base and the surface of the pallet are provided with locating devices. The locating devices are used for preventing the sliding of the concave anchor ring base on the pallet and avoiding the shearing formed to steel stands when the steel stands of the anchor body is pre-tightened. The turning anchor is pivotally connected by the spherical surface which consists of the spherical surface anchor ring and the concave anchor ring base, can be applicable to being used under the situations where the tunnel rock surface is not vertical to the anchor drilling bore or inclined to the tunnel rock surface by arbitary angle or the rock surface is unsmooth, ensures that the bearing capability of the anchor is not reduced and sufficiently exerts the supporting capability of the anchor on the top plate.
