Multifunctional portal device of suspension bridge pillar top

Abstract

The invention provides a multifunctional portal device of a suspension bridge pillar top, and belongs to the field of construction devices of suspension bridges. The multifunctional portal device of the suspension bridge pillar top comprises a field mounted portal body, wherein the field mounted portal body comprises a supporting truss system, a working platform, a catwalk turning cable saddle, a lifting system and a traction system; the working platform is connected to the upper end of the supporting truss system; the lower end of the supporting truss system is anchored to the suspension bridge pillar top through an anchoring system; and the catwalk turning cable saddle, the lifting system and the traction system are respectively connected with the supporting truss system. The multifunctional portal device of the suspension bridge pillar top is provided with the field mounted portal body, a portal is divided into different blocks which are assembled on a tower top, requirements on field hoisting are met, conveying, mounting and machining can be facilitated further, construction installation is simplified, the different blocks of the portal can be combined with the catwalk turning cable saddle at the tower top, the portal is stressed safely, effects of the portal can be fully achieved in various stages of installation construction of an upper structure of the suspension bridge, and multifunction of the portal is fulfilled really.

Description

technical field

[0001] The invention relates to the field of suspension bridge construction devices, in particular to a multifunctional gantry device at the top of a suspension bridge pier. Background technique

[0002] In order to meet the lifting and installation of the main cable saddle, it is convenient for the construction of catwalks, traction systems, cable strand tensioning systems and other temporary facilities, as well as the installation of construction equipment such as cable tightening machines, wire winding machines, and cable cranes, and at the same time facilitates the subsequent erection of the main cable , cable clips and slings, steel box girders and other permanent structures, and a door frame is set on the top of the tower. Because the overall weight of the conventional door frame is too large, it is not conducive to hoisting and installation. It is necessary to simplify the design of the door frame to facilitate hoisting, installation, and transportatio...
