HYDRAULIC-CYLINDER WITH PENING AND CLOSING APPARATUS FOR DAM

摘要

An apparatus for opening and closing a water gate by a hydraulic pressure cylinder is provided to reduce the manufacturing and installing cost by combining a wire rope guided through a flowing pulley at the lower end of both sections of the water gate. An apparatus for opening and closing a water gate structure(100) and a water gate(200) by a hydraulic pressure cylinder(50) includes a wire rope(10) mounted at both sides of the water gate, wherein one end is installed at the lower end of the side surface of the water gate and the other end is installed at the upper part of the structure; fixing pulleys(20) mounted at the upper part of the structure to guide the wire rope; a flowing pulley(30) moving/guiding the wire rope guide up and down by the fixing pulleys; and the hydraulic pressure cylinder mounted with a round bar(40) formed to move the flowing pulley up and down and mounted at the upper part of the structure. The fixing pulleys are plurally installed to prevent the position of the hydraulic pressure cylinder from being limited at the upper part of the structure.
