Abstract
PURPOSE: To provide a support leg device which takes a high decelerating ratio and has a self-lock function, by a method wherein a rack is mounted in a longitudinal direction, and a worm, which engages the rack and rotates through the working of a reduction gear, is installed on a work ship.
CONSTITUTION: When a work ship 3 on the sea arrives at a given position, with a worm 8 turned by means of a motor 5, a support leg 1 is lowered to the sea bed through the rack of the support leg 1. The support leg 1, which is of a square post formed in a truss structure, is constituted such that the racks are welded at cylinder materials located at 4 corners. The rack 2 engages with the worm 8, being pivotably driven through a motor 5, a reduction gear 6, a pinion gear 7, and a gear 4 which are securly istalled on a frame 9.
