The utility model discloses a vertical shaft operation anti -falling buffer protection structure relates to vertical shaft anti -falling technical field, the utility model discloses a mounting ring, first arc plate, the quantity is multiple, and multiple first arc plate is in
annular array distribution and is installed in the bottom of mounting ring, first adjusting
assembly, first adjusting
assembly is installed in the bottom end of mounting ring, and it is used to drive multiple first arc plate to gather or separate and open, the utility model discloses a first arc plate and first adjusting
assembly fast positioning form rigid intercepting surface, and the overall position of fixing device, and second arc plate cooperation guard board and buffer component, and the falling
impact is converted into elastic
potential energy and is gradually attenuated, and the structural
peak load is reduced significantly, and the protectivity of this device is greatly improved, and this device is installed in the vertical shaft of different diameters, need not
cutting welding to adapt to different well
diameter and lining error, and the dismounting is efficient, and is repeatedly used, and the construction efficiency is greatly improved.
