The invention relates to the field of steel tower hoisting and construction at sea, and discloses a steel tower sliding and vertical rotation method, which includes a transport ship, a spreader, a sliding vertical rotation device and a floating crane. Slide rails are set on the deck of the transport ship. The method includes the following steps: transporting the steel tower to the first position and being on the same line with the floating crane; setting a connecting seat in the middle of the steel tower, and connecting the steel tower with the floating crane through the connecting seat The steel tower is horizontally lying on the slide rail; the steel tower is displaced from the horizontal state to the vertical state under the joint action of the floating crane and the sliding vertical rotation device. The invention can solve the problem that in the current vertical rotation of steel towers, the mutual pull operation of two symmetrical steel towers is needed and the simultaneous construction and manufacture of bridges and steel towers cannot be guaranteed.
Description
technical field [0001] The invention relates to the field of offshore hoisting construction of steel towers, in particular to a method for sliding and vertically rotating steel towers. Background technique [0002] With the development of the national economy and science and technology, the construction of cross-sea bridges has also been gradually developed. [0003] At present, for the installation of bridge steel towers, the method of segmental hoisting is generally adopted, and on-site assembly work is carried out on the construction platform set up at high altitude. The problem is that some adopt the method of "mutually pulling vertical rotation". This method uses the bridge deck as a welding construction platform, and uses the steel tower on one side as a support to carry out the vertical rotation of the steel tower on the other side. Finally, the vertical rotation of the steel towers on both sides is completed, and some of them use two large floating cranes to lift th...
