Super-huge type vertical combination bearing device

Abstract

The invention relates to a super-huge type vertical combination bearing device. The super-huge type vertical combination bearing device comprises a vertical steel pipe column with the outer diameter of 2m, and a combination bearing, wherein a step tubular bearing base is coaxially arranged in the middle of the steel pipe column; an annular support platform is arranged at the lower part of the steel pipe column; the combination bearing comprises a center bearing which is vertically arranged and a planar bearing; the center bearing comprises an inner ring, a middle composite layer and an outer ring, and coats in the middle of the bearing base; a tube shaft-shaped connecting base coats and connects the outer ring; an annular upper sealing pressure plate is arranged between the axial upper part of the center bearing and the connecting base; an annular lower sealing pressure plate is arranged between the axial lower part of the center bearing and the connecting base; a tubular support arm connecting base fixedly coats the connecting base; and the planar bearing is arranged on the support platform at the lower part of the steel pipe column. The device can bear the radial load of 800t and the axial load of 300t, and is the biggest domestic combination bearing with the highest bearing capacity at present, and is the only domestic composite bearing device consisting of the vertical bearing and the planar bearing.

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...
