Abstract

The invention discloses a swivel ball joint and a mounting method thereof. The swivel ball joint comprises a lower ball joint and an upper ball joint arranged above the lower ball joint, wherein a positioning pin hole is formed in the central position of the upper ball joint; a pin shaft is fixedly arranged on the lower ball joint and rotationally connected into the positioning pin hole; both theupper ball joint and the lower ball joint are arranged in the shape of a circle; the top surface of the lower ball joint is a concave sphere; the bottom surface of the upper ball joint is set to a convex sphere which fits the top surface of the lower ball joint; a plurality of upper anchor bolts are uniformly arranged on a support of the upper ball joint; a plurality of lower anchor bolts are uniformly arranged on a support of the lower ball joint; and the upper anchor bolts and the lower anchor bolts are symmetrically arranged. By the adoption of the swivel ball joint disclosed by the invention, the defect that a conventional ball joint is complex to mount and difficult to position can be overcome; the high-efficiency, high-precision and high-quality mounting of the swivel ball joint canbe achieved; and the smooth swiveling can be ensured.

Description

technical field [0001] The invention relates to the technical field of swivel bridge construction, in particular to a swivel spherical joint and an installation method thereof. Background technique [0002] A swivel bridge is a bridge constructed using the swivel method. Bridge swivel construction refers to a construction method in which the bridge structure is formed (cast or spliced) at a position other than the design axis, and then put in place by swivel. It converts operations over obstacles to operations onshore or near the surface. [0003] Compared with the traditional in-situ support cast-in-place, cantilever pouring, etc., swivel construction has the advantages of construction safety, no impact on navigation, and uninterrupted traffic under the bridge. Therefore, this construction method develops rapidly and is more and more widely used, especially for construction It is a railway overpass with heavy traffic and strict safety requirements. [0004] The ball join...
