Stepless height adjusting and force measuring spherical bearing

Abstract

The invention discloses a stepless height adjusting and force measuring spherical bearing. The stepless height adjusting and force measuring spherical bearing comprises an upper bearing plate, a plane tetrafluoro slide plate, a height adjusting lining plate, a height adjusting support, a cylinder sleeve, a lower bearing plate, a force measuring system, a basin plug and a spherical tetrafluoro slide plate; a mirror finished stainless steel plate is welded on the bottom surface of the upper bearing seat and forms a plane friction pair together with the plane tetrafluoro slide plate; meanwhile, the plane tetrafluoro slide plate is embedded in a groove of the height adjusting lining plate; the height adjusting support is matched with the height adjusting lining plate; the spherical tetrafluoro slide plate is positioned in a spherical groove formed by the height adjusting support and the basin plug; the basin plug is positioned within an inner cavity of the cylinder sleeve; through an oil seal and a sealing ring, the basin plug forms a closed inner cavity together with a retainer ring matched with the sealing ring; and the force measuring system is in communication with the closed inner cavity. The stepless height adjusting and force measuring spherical bearing is used for monitoring and measuring various vertical loads and can also be used for adjusting elevations in time when bridge piers and abutments suffer settling.

Description

technical field [0001] The invention relates to a support capable of realizing stepless height adjustment and real-time monitoring of various loads in the vertical direction of structures, specifically a stepless height adjustment force-measuring spherical support. Background technique [0002] With the continuous development of my country's scientific and technological level, the span of bridge structure is getting larger and larger, the structural forms are more and more, and the functional requirements are gradually increasing. The common point of these long-span complex structure bridges is that they all belong to high-order hyperstatically indeterminate structures, and their internal force calculations are extremely complicated. At the same time, after the bridge is completed, the abutment may settle within a certain period of time, which will cause the redistribution of the internal force of the bridge structure, which will have a catastrophic effect on the high-speed ...
