Embodiment Construction

[0030] The technical solution in this embodiment will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as figure 1 , 2 As shown, the swivel device for spanning the existing railway portal piers in this embodiment includes an upper spherical hinge 1 and a lower spherical hinge 2 arranged between the upper and lower railway portal piers. The upper spherical hinge 1 includes a top plate and a The lower convex spherical structure, the lower ball joint 2 includes a bottom plate and a concave spherical structure arranged on the bottom plate. The sliding part arranged around the convex spherical structur...

Abstract

The invention relates to a turning device for crossing existing railway portal piers and an installing method thereof. The turning device comprises an upper spherical hinge and a lower spherical hingearranged between the upper railway portal pier and the lower railway portal pier, the upper spherical hinge comprises a top plate and a convex spherical structure arranged under the top plate, the lower spherical hinge comprises a bottom plate and a concave spherical structure arranged on the bottom plate, the convex spherical structure is slidably arranged on the concave spherical structure to form a rotary friction pair, and an annular slideway is arranged around the concave spherical structure. The top plate is connected with a plurality of sliding pieces which are arranged around the convex spherical surface structure, and the sliding pieces are arranged on the slideway. According to the turning device for the crossing existing railway portal piers and the installing method thereof, one-step installation of the turning device can be realized, the installation form is changed and the installation mode is simplified. The mounting time of the spherical hinges is greatly saved, the mounting precision is high, the quality is reliable, and the turning of the crossing railway portal piers can be realized.

Description

technical field [0001] The invention relates to a swivel device, in particular to a swivel device for crossing an existing railway portal pier, and an installation method thereof, relating to the field of bridge engineering. Background technique [0002] Bridge construction often needs to cross places such as railways, highways, canyons, etc. Due to the constraints of transportation or the inability to construct above them, these places must be constructed by prefabricating beams. [0003] At present, the construction of this type of bridge mainly adopts the beam body horizontal push or swivel construction method. The beam body horizontal push construction is divided into two types: horizontal push and vertical push. Both methods need to build temporary piers and temporary slides. On the slider, the slider is connected to the tension jack on the opposite side through a wire rope, and the beam body is slowly moved to the position of the beam body through the jack pulling the ...
