Hinge joint assembly of sealed centripetal oscillating bearing steel structure

Abstract

The invention discloses a hinge joint assembly of a sealed centripetal oscillating bearing steel structure, and relates to a hinge joint of an oscillating bearing steel structure. The hinge joint assembly comprises centripetal oscillating bearings, seal rings, a pin shaft, a middle ear plate, a pair of double ear plates, pin shaft cover plates, a pair of annular flitches, bolts, nuts, spring washers and a pair of locating sleeves, wherein the centripetal oscillating bearings are provided with inner rings and outer rings; the inner rings and the outer rings can rotate and swing oppositely; the centripetal oscillating bearings are mounted in bearing holes of the middle ear plate in a tight matching manner; the annular flitches press the outer rings of the centripetal oscillating bearings and lock with the bolts; the pin shaft penetrates through the inner rings of the centripetal oscillating bearings; the locating sleeves are sleeved into the two ends of the pin shaft respectively and close to the end faces of the inner rings of the centripetal oscillating bearings; the seal rings tightly sleeve the locating sleeves and are close to the annular flitches; the double ear plates are matched with the pin shaft respectively, are close to the locating sleeves and tightly press the seal rings; and the pin shaft cover plates tightly press the locating sleeves and lock with the bolts on the pin shaft to form the hinge joint assembly of the sealed centripetal oscillating bearing steel structure.

Description

technical field [0001] The invention relates to a joint bearing steel structure hinge, in particular to a sealed centripetal joint bearing steel structure hinge assembly mainly used in steel structure engineering. Background technique [0002] Hinge joints are inseparable from steel structure construction projects, but conventional pin-type hinge joints can rotate freely in one direction, but cannot rotate in other directions, and the stress generated by rigid structures cannot be eliminated. With the rapid development of society, such nodes can no longer meet the requirements of innovative design and complex force-bearing space structure system, and the connection forms of the structure have become increasingly diversified, requiring certain nodes to have the ability of space rotation and force transmission. characteristic. [0003] Chinese patent CN2937297 discloses a steel structure rod end universal hinge joint device mainly used for the hinge connection between steel s...
