[0025] The working principle of this embodiment is as follows:
[0026] First, refer to the attached Figure 2, the hook tail frame clamping device 6 is extended into the frame of the hook tail frame workpiece 8 on the hook tail frame maintenance line through the lifting frame 2 and the front and rear moving frames 3, and then the two telescopic parts of the hook tail frame clamping device 6 are expanded outward to press against the two inner side walls of the hook tail frame workpiece 8 from the inside to the outside, so that the hook tail frame clamping device 6 clamps the hook tail frame workpiece 8, and then refer to the attached Figure 3 , lift the hook tail frame workpiece 8 to a suitable height through the lifting frame 2, then rotate the hook tail frame workpiece 8 to the installation direction of the hook tail frame claw 11 through the rotary drive device 5, and then move the hook tail frame workpiece 8 to the hook tail frame claw 11 through the front and rear moving frame 3, and finally the two telescopic parts of the hook tail frame clamping device 6 shrink inward and disengage from the hook tail frame workpiece 8, thus completing the loading step of the hook tail frame workpiece 8, and the above steps can be reversed to unload from the hook tail frame claw 11.
