APPARATUS FOR ALIGNING FLANGE BOLT HOLE OF PIPE WHICH PENETRATE INTERNAL PARTITION OF SHIP BLOCK

摘要

PURPOSE: A flange bolt hole aligner of a pipe passing through an inner baffle of a ship block is provided to detect the position of laser beam irradiated on a marking line drawn on the baffle and align the position of flange. CONSTITUTION: A flange bolt hole aligner of a pipe passing through an inner baffle of a ship block comprises a body(110) with a flat bottom surface, a pair of fixing parts(120), and a pair of laser irradiating parts(130). The fixing parts includes a structure projected from the bottom of the body to be inserted into a bolt hole of a flange, and are coupled to the body to move left and right along the bottom surface of the body. The laser irradiating parts are installed in the body and irradiate laser beam from the top of the body to a marking line drawn on the baffle of the ship block. The center of the laser irradiating parts is located directly above on a central line passing through the center of the two fixing parts.
