Abstract

The invention relates to an extra-large vertical combined bearing device. It includes an upright steel pipe column with an outer diameter of 2 meters and a composite bearing. The middle part of the steel pipe column is coaxially provided with a stepped tubular bearing seat, and the lower part of the steel pipe column is provided with a ring-shaped support platform; the composite bearing includes a central bearing arranged vertically and plane bearings; the central bearing includes an inner ring, an intermediate composite layer and an outer ring, and is sleeved in the middle of the bearing seat; the outer ring is sleeved with a tube shaft-shaped connecting seat, and the axial upper part of the central bearing is connected to the There is a ring-shaped upper sealing pressure plate between the seats, and a ring-shaped lower sealing pressure plate between the lower part and the connection seat; a tubular support arm connection seat is provided on the fixed sleeve of the connection seat; Plane bearing: This device can withstand radial load of 800t and axial load of 300t. It is currently the largest combined bearing with the highest bearing capacity in China, and it is also the only composite bearing device composed of vertical bearing and planar bearing in China.

Description

technical field [0001] The invention belongs to the technical field of gates in water conservancy and hydropower projects, and relates to an extra-large bearing device used for gates. Background technique [0002] The hinge bearing is an important load-bearing part of the gate. It is characterized by being able to withstand large radial loads and certain axial loads. It is mostly used in arc gate hinges. The bearings are arranged horizontally and are generally located above the water surface. In recent years, bottom shaft-driven flap gates have become more and more widely used, so the underwater arrangement of bearings has become more and more common. Before the appearance of this bearing device, the largest joint bearing in China was used on the estuary gate of Suzhou Creek in Shanghai. The inner diameter of the bearing was 2000mm and it was arranged horizontally. According to mechanical analysis, the radial load of the joint bearing is 490t, and theoretically, it basicall...
