Rig appearance frame with adjustable angle

The utility model provides a rig appearance frame with adjustable angle, belongs to the pore -creating device among the hydraulic and hydroelectric engineering, in particular to adjusting device that can control rig pore -creating angle. It includes the support frame, and triangular support frame is constituteed by last horizontal pole, sheer pole, little horizontal pole and diagonal brace to the support frame, and there is the inserted bar support frame below, and the rig is installed on the support frame. Its key technology installs an angle adjusting device on last horizontal pole, angle adjusting device is H shape, and the rig lower extreme is equipped with down the fulcrum, and install on angle adjusting device the rig upper end, and the rig lower extreme is installed on the sheer pole through lower fulcrum. The utility model discloses the beneficial effect who has is: the utility model discloses installation angle adjusting device on supporting the appearance frame possesses the angle modulation function, and angular discrepancy corrects in the realization work progress. When the rig arouses because of the factor that can't predict that the rig angle changes with the design slope in tool joint, can correct the angle fast succinctly.
