Description

Technical Field

[0001] The invention relates to the technical field of long-span bridge construction, and in particular to a cable installation and lifting device for a cable-stayed bridge. Background Art

[0002] With the rapid development of my country's economy, the status of transportation engineering construction is particularly important; when roads have to cross large rivers, lakes, seas, railways, valleys and other areas with complex geological conditions or navigation boundaries, cable-stayed bridges, as a bridge that has both large spanning capacity and can reduce investment costs and construction difficulty, are increasingly used in current road construction. Especially in recent years, with the development of science and technology, cable-stayed bridges have been widely used in highways, railways, and dual-use bridges, and their spans are getting larger and larger. In such a background, cable-stayed bridges often encounter many problems during construction. For example, during the construction of cable-stayed bridges, a tower crane next to the tower column is usually used to complete the installation of the cable-stayed cable on the tower. However, as the span of the cable-stayed bridge increases, the tower column height increases, the length of the cable-stayed cable becomes longer and longer, and the weight of the cable-stayed cable becomes heavier. After the limited lifting capacity and height change of the tower crane, various insecurities of the tower crane are increased; and due to some restrictions on the shape of the tower column, some tower cranes are farther and farther away from the tower column during installation, which increases the safety risk of the tower crane; the larger the span of the cable-stayed bridge and the higher the tower column, the more cable-stayed cables there are, and the longer the installation time is, especially in typhoon areas, the higher the installation risk and construction cost of the cable-stayed cable; currently, winches are also used for installation on site, but the forms are different and cannot be reused, resulting in a large increase in construction costs and a large waste of resources. For this reason, it is particularly important to study a device suitable for lifting and installing cables for large-span cable-stayed bridges. Summary of the invention
