Problems solved by technology
[0004] The two supports at the upper end of the rigging platform are above the water surface, and the operation is simple and easy to remove. The two supports at the lower end are generally easy to fall below the water curve. During offshore demolition operations, they are often affected by changes in tidal levels and are not easy to remove. Completed the disengagement operation, so improvement is needed

The invention provides a rapid disengaging structure of a rigging platform. The rapid disengaging structure of the rigging platform comprises supporting rods arranged at four corner ends of the rigging platform respectively, wherein supporting rods located at the two corner ends at the upper portion of the rigging platform are fixedly connected with the upper portion of a conduit frame. The rapid disengaging structure of the rigging platform is characterized in that supporting rods located at the two corner ends at the lower portion of the rigging frame are respectively provided with a sleeve, supporting rods are arranged at the positions where the conduit frame is connected with the two sleeves of the supporting rods at the two corner ends of the lower portion of the rigging platform in a sleeved mode, the supporting rods are provided with sleeves, and the inner diameters of the sleeves are larger than the inner diameters of the two sleeves of the supporting rods at the corner ends of the lower portion of the rigging platform respectively so that the two sleeves of the supporting rods at the corner ends of the lower portion of the rigging platform can be inserted into or disengaged from the corresponding sleeves of the supporting rods of the conduit frame. The rapid disengaging structure of the rigging platform is simple in structure, convenient to operate, capable of reducing workloads and construction time of offshore construction and capable of effectively reducing risks of offshore operation.
Description
technical field [0001] The invention relates to a quick release structure of a rigging platform. Background technique [0002] The jacket mainly plays the role of supporting the load of the upper module, and the height of the jacket in deeper water is higher, and the horizontal construction method is often used in the construction process. During the installation process of the horizontal construction jacket, the jacket needs to be straightened. There are usually two methods for the jacket righting at present: one is to use the water filling system attached to the jacket and the floating crane to assist in completing the jacket righting. The second is to use the small hole water filling method combined with the water filling system (or the buoy to force the righting) to complete the righting, and then combine the floating crane to sit on the bottom and put it in place. These two methods are inseparable from the assistance of floating cranes, so before entering the water, t...
