Embodiment Construction
[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0026] like figure 1 and image 3 As shown, an installation base of an offshore platform crane includes a base 1 and a bearing device 2; the base 1 includes an upper base 11 and a lower base 12; the lower half of the upper base 11 is a square column structure 111 , the upper half is a trapezoidal platform structure 112 transition, and its top is a cylindrical structure 113 transition; the lower base 12 is a square column structure; the upper base 11 and the lower base 12 are welded and fixed to each other; the base 1 A circular column hole 4 for installing pile legs is provided through the interior, and the top of the circular column hole 4 and the cylindrical structure 113 are concentric ring structures;
[0027] A plurality of first rib plates 5 are arranged between the circular column hole 4 an...

A mounting base of an ocean platform crane comprises a pedestal and a bearing device. The pedestal comprises an upper pedestal body and a lower pedestal body, the lower half part of the upper pedestal body is of a square cylinder structure, the upper half part of the upper pedestal body is of a trapezoidal-table structure for transition, and the top of the upper pedestal body is of a cylindrical structure for transition. The lower pedestal body is of a square cylinder structure. A cylindrical hole is formed in the pedestal in a penetrating mode, the top of the cylindrical hole and the cylindrical structure are of a concentric-ring structure, and first reinforcing rib plates are arranged between the cylindrical hole and the inner wall of the upper pedestal body and are symmetrically distributed with the cylindrical hole as the axis center. Edges of the two sides of each first reinforcing rib plate are matched with the cross section between the cylindrical hole and the inner wall of the upper pedestal body in shape, the edge of the top of each first reinforcing rib plate upwards tilts from the cylindrical hole to the inner wall of the cylindrical structure, and the tail end of each first reinforcing rib plate is in arc transition. The bearing device comprises a rotating device supporting ring and is mounted at the top of the cylindrical structure. The mounting base of the ocean platform crane is stable in bearing, more uniform in stress and more compact, stable and reasonable in structure, and the manufacturing cost is lowered.
Description
technical field [0001] The invention relates to the technical field of offshore platform lifting, in particular to an installation base of an offshore platform crane. Background technique [0002] With the development of offshore wind power and oil exploration industries, the demand for offshore platform cranes is increasing, and in the ocean's windy and wave environment and the particularity of large-scale operations, the requirements for the structure of offshore platform cranes are gradually increasing. Increase. [0003] The installation base of the existing offshore platform crane uses a single straight cylindrical structure as the support of the base to meet the requirements for the strength and stability of the upper support of the crane, and with the increase of the bearing weight, the installation base The volume of the seat also increases accordingly, so there is a problem that the space occupied by the installation base is large.
