Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a bridge construction device, and specifically to an auxiliary bridge tower vertical rotation device. Background Art

[0002] With the development of my country's economy, more and more long-span bridges need to be built, and the structural forms of bridges are becoming more and more novel. The steel tower of the cable-stayed bridge without backstay includes the bridge foundation and the steel tower. The bridge foundation and the steel tower are processed separately. After the bridge foundation is built on the river surface, the processed steel tower is hoisted onto the bridge foundation, and then the steel tower is processed and fixed.

[0003] In the prior art, commonly used installation schemes for steel towers include an in-situ vertical hanging and splicing scheme and a vertical rotation scheme. The in-situ vertical hanging and splicing scheme requires high-altitude hoisting and splicing. High-altitude and three-dimensional operations have greater safety risks. It is difficult to ensure the linear accuracy of the steel arch tower, which has an adverse effect on the appearance of the steel arch tower. In addition, the on-site welding quality between the steel tower segments is difficult to control. If the weld quality does not meet the design and specification requirements, it will have an adverse effect on the structural strength and stiffness of the steel tower.

[0004] In the vertical rotation scheme, the bridge tower is moved to the installation position of the bridge foundation, and the bridge tower is placed horizontally on the bridge foundation. The bridge tower is pulled to a preset angle by a vertical rotation cylinder, and then the bridge tower is fixed. Before the vertical rotation cylinder pulls up the bridge tower, it is necessary to use auxiliary equipment to lift the bridge tower so that there is a certain force angle between the bridge tower and the bridge foundation, which is convenient for the vertical rotation cylinder to pull up the bridge tower. In the prior art, the operation of installing the bridge tower using the vertical rotation scheme is cumbersome and the construction cost is high. Utility Model Content
