Description

Technical Field

[0001] The utility model relates to the technical field of bridge cable tower construction, in particular to a jack used for pushing between a cross brace and a distribution beam. Background Art

[0002] With the development of economy, the navigation traffic in rivers has become more and more busy. In order to reduce the impact on shipping, the span of cross-river bridges is getting larger and larger, and the height of cable towers is getting higher and higher. In order to improve the stiffness of cable towers and reduce the problem of cracking of large-section cable towers, more and more large-span cable tower structures tend to be spatial diamond-shaped four-tower structures.

[0003] After the cross brace and distribution beam of the existing space diamond-shaped four-tower main tower joint structure are welded and fixed, it is necessary to perform a jacking operation between the cross brace and the distribution beam during a period of relatively constant temperature. Four jacks are set at one end of each steel pipe, and two working jacks (the jacks must be calibrated and qualified first) are used for synchronous jacking. The jacking operation of the cross brace of each layer requires the jack to reach a corresponding thrust to ensure the stability of the structure. The existing device is not convenient for controlling the thrust of the jack, so a jack for jacking between the cross brace and the distribution beam is needed to improve the above problem.
