Problems solved by technology

[0008] The main purpose of the present invention is to improve the structure of the crane in view of the defects of the current crane setting method, and provide a bridge deck crane on a rope, which is supported on the main girder of the steel beam section, which can avoid the pressure of the crane's own weight. It can cause deformation of the steel girder section, solve the problem of misalignment during docking, and does not affect the installation of the cable stays. It can also integrate the functions of the bridge deck crane to reduce construction machinery, reduce construction costs, and improve construction efficiency.

Abstract

The invention belongs to the field of bridge engineering and particularly relates to a cable-mounted deck derrick crane applicable to large-span stay cable steel-concrete composite girder bridge construction. The deck derrick crane comprises two main trusses, a plurality of connecting rods connecting the two main trusses, an anchoring device, a traveling device and hydraulic lifting systems, wherein each main truss comprises inner rhombic truss pieces and outer rhombic truss pieces which are symmetrical relative the corresponding stay cable central line vertically arranged above main longitudinal beam lifting lugs, the rhombic truss pieces are in parallel bolt connection through profile steel, the two hydraulic lifting systems are arranged at the tops of the rhombus tips of the main trusses, and bridge deck slab cranes are arranged on the upper-cord beams of the inner rhombic truss pieces of the two main trusses.

Description

technical field [0001] The invention belongs to the field of bridge engineering, and in particular relates to a cable-riding bridge deck crane used for the construction of long-span cable-stayed steel-concrete composite beam bridges. Background technique [0002] A cable-stayed bridge is a bridge in which the main girder is directly pulled on the bridge tower by cables. Due to the horizontal component force of the cables, the cable-stayed bridge bears a large compressive stress. Therefore, the beam body in the form of a steel-concrete composite beam is often used in the design to give full play to the tensile performance of the steel structure and the compression resistance of the concrete. Performance, therefore, steel-concrete composite girder cable-stayed bridges are developing more and more rapidly at home and abroad. [0003] figure 1 Shown is a cross-sectional schematic diagram of a steel-concrete composite beam body, including a steel beam, a concrete deck 4 on the ...
