VARIABLE HEIGHT TYPE SUPPORTER OF HULL BLOCK

摘要

Disclosed is a height-variable hull block supporter configured to arbitrarily change the height of a hull block supporter. The height-variable hull block supporter comprises: an outer casing pipe vertically installed in a base frame; an inner support pipe arranged on the outer casing pipe to be lifted; a first sheave arranged on the outer casing pipe to be rotated; a second sheave coupled to the bottom of the inner support pipe; and a winch wire having one end fixed on the outer casing pipe and the other end passing the second sheave and the first sheave in order. The inner support pipe and the second sheave are lifted by the winch wire to support a hull block. Thus, the present invention can correspond to various support heights of the block with one supporter by arbitrarily setting the support height of the hull block; does not need individual supporters per height; is free from the limitation of selecting the height of an attached pillar cap; and does not need a separate fine adjusting device. Also, the present invention can prevent safety accidents not by requiring the high place work of a worker, and can drastically improve productivity by making the installation work convenient.
