Installation method for integrated prefabrication of anchor platform and anchor mouth

Abstract

The invention provides an installation method for integrated prefabrication of an anchor platform and an anchor mouth. The installation method for integrated prefabrication of the anchor platform and the anchor mouth comprises the following steps that firstly, the structural drawing of the anchor platform and all components of the anchor platform is drawn based on computer aided drawing, and a numerically-controlled file is generated so that a numerically-controlled forming system can be guided to machine components such as a panel, a wrist plate, an annular connecting piece, a surrounding plate and a hawse pipe; secondly, the components such as the panel, the wrist plate, the annular connecting piece, the surrounding plate and the hawse pipe are installed and welded, so that an organic integrity is formed; finally, the organic integrity is hoisted onto an outer plate, of a segmented structure, of a ship body to be positioned, welded and fixed. By the adoption of the installation method for integrated prefabrication of the anchor platform and the anchor mouth, integrated installation of the components such as the anchor platform can be achieved in a one-time mode when the ship body is re-manufactured in a segmented mode, a small number of crane sources are occupied, integrated prefabrication of the anchor platform and the anchor mouth can be achieved conveniently and rapidly, manpower and material resources are saved, and the cycle of a slipway (dock) is shortened.

Description

technical field [0001] The invention relates to construction engineering in the shipbuilding industry, in particular to an installation method for the integral prefabrication of the anchor platform and anchor lip ground. Background technique [0002] At present, the anchor platform panel and half of the brackets are prefabricated on the ground, but the accuracy is very poor, and they have to be disassembled and reassembled in the end. The rest of the anchor coaming, the remaining half of the brackets and the anchor lip are loosely assembled after the bow general section is installed (close to launching). The following problems often exist during the construction process: (1) The operating environment is complex and there are many overlapping processes , with great potential safety hazards; (2) In bulk, the positioning datum is difficult to find, the assembly is difficult, and the resources of the crane are tight, which leads to many assembly and welding man-hours, and the ac...
