PURPOSE:The mounting structure which can be surely fixed and can be easily interchanged, by mounting the cannon to the frame through the swivel arm so as to be able to freely swing, and also, by strongly pushing the cannon into the groove installed in the frame through the wing type engaging part so as to be fixed. CONSTITUTION:For dismounting the cannon 1, the hydraulic cylinder 5 of the clampers 15a, 15b, is actuated to release the tightening of the washer 14. Next, the rod of the hydraulic cylinder 4 of the swivel arm 2 is pulled back, and the swivel arm 2 is turned to take the cannon 1 out of the pass line. After that, the cannon 1 is hanged up by the unillustrated crane and is removed away. Next, the cannon 1 of desired size is transported to the position of the swivel arm 2 by the crane, and is brought down so as to engage the arm 11 with the hook 2a; after that, the hydraulic cylinder 5 of the clampers 15a, 15b, and the hydraulic cylinder 4 are actuated to tighten the washer 14 of the cannon 1 for fixing it at the specified position. As a result, the wing type engaging part 12 is strongly pushed into the groove 13 of the frame 101. |
