An overall sliding and vertical rotation device for a steel cable tower

Abstract

The invention discloses an integral slippage and vertical rotation device for a steel pylon. The slippage and vertical rotation device comprises a floating crane device, a rotating part, a sliding part, at least two sliding rails and a traction device. The floating crane device is connected with the steel pylon and used for providing floating crane force of the steel pylon. One end of the rotating part is fixedly connected with the steel pylon. The sliding part is fixedly connected with the other end of the rotating part so that the steel pylon and the sliding part can rotate relative to each other. The sliding rails are arranged side by side in a spaced manner. The sliding part is arranged on the sliding rails in a sliding manner. The traction device is used for providing traction force for the steel pylon to slide and penetrates the gaps between the sliding rails to be connected with the sliding part. The integral slippage and vertical rotation device solves the technical problem that integral slippage and vertical rotation of a steel pylon installed in the prior art are difficult, and achieves the technical effect that the steel pylon can fast and safely perform slippage and vertical rotation in the installing process.

Description

technical field [0001] The invention relates to the technical field of hoisting construction, in particular to an overall sliding and vertical rotation device for a steel cable tower. Background technique [0002] With the continuous improvement of bridge structure theory and the application of more new materials, modern bridges are developing towards larger spans. Due to the continuous development of tower formwork technology and concrete pouring technology, most of the suspension bridges and cable-stayed bridges in the world use concrete towers. Compared with concrete structures, steel structures have many advantages, and steel structures are better at resisting earthquakes. Steel structures are widely used in various fields. In foreign countries, the application of steel cable towers in cable-stayed bridges or suspension bridges has been very mature. In my country, steel cable towers are just in the application period. The steel cable towers of the Hong Kong-Zhuhai Brid...
