A method for hanging and installing cable bridges under high-altitude platforms

Abstract

The invention discloses an installation method for suspending a cable bridge under a high-altitude platform. The method comprises the steps of production and installation of a mobile platform, installation of the cable bridge, laying of a spring board and a safety rope, cable laying and subsequent disassembly and the like. The mobile platform comprises a steel tube erect rod, a cross beam, a skipping board, and a right-angle coupler, the steel tube erect rod comprises a left erect rod and a right erect rod, the bridge installation position is surveyed and mapped on site based on an operation map, the steel tube right-angle coupler is utilized to connect the left erect rod and the right erect rod, and the left erect rod, the right erect rod and a lifting lug at the upper end are connected through bolts, which facilitates assembly and disassembly. By means of the installation method for suspending the cable bridge under the high-altitude platform, the operation tasks of installation of the bridge and laying of cables in the bridge can be completed safely, efficiently, conveniently and with good quality, and the rental fee of all-around scaffolds is saved; the problem that in a conventional installation method, a passage is occupied for a long time is solved, and the installation method for suspending the cable bridge under the high-altitude platform has the advantages that the installation is convenient, the operation is safe, the operation cost is reduced, and the passage is not occupied and the like.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a method for hanging and installing a cable bridge under a high-altitude platform. Background technique [0002] The steel structure of the steelmaking workshop of the smelting project is high, and the process platform has many layers, so the installation of the bridge is difficult, especially the converter platform on the first floor, which is usually 8 to 11 meters above the ground. Steel pipe scaffolding, erecting a manual operation installation platform, the scaffolding is placed for a long time after erection, and can only be removed after the cables in the bridge frame are laid and the bridge cover plate is installed. It will be unfavorable and increase the construction cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a method for hanging and i...
