[0002] During the construction of offshore wind power, the fan blades need to be assembled on the offshore wind power construction platform. Sometimes, in order to meet the needs of assembling the fan blades, an oil drilling platform is transformed to form it. The offshore wind power construction platform usually needs to be equipped with a crane for hoisting the fan blades (see Chinese Patent Publication No. CN221030047U). However, for the offshore wind power construction platform transformed from an oil drilling platform, the space is small, and there is a problem that the installation of the marine engineering crane cannot be satisfied. Content of the Utility Model

[0030] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0031] As Figures 1 to 9 shown.

[0032] The technical solution of the present application is that an extended platform 2 and an extended outer platform 6 are fixedly connected by welding or detachably fixed by bolts on the side of the drilling platform 7, and the platform space on the drilling platform 7 is expanded through the extended platform 2 and the extended outer platform 6.

[0033] Traveling tracks 51 are installed on the extended platform 2 and the drilling platform 7, and a crawler crane 52 is installed on the traveling tracks 51. A counterweight platform 53 for placing configuration blocks is installed on the drilling platform 7 at one end of the traveling tracks 51, and a platform outer anti-sway shelf 3 is installed on the extended outer platform 6 to support the boom 5 of the crawler crane 52, thereby constituting a crawler crane layout structure on an oil drilling platform.

[0034] An offshore crane 71 is installed on the extended platform 2, and a platform outer anti-sway shelf 3 is installed on the extended outer platform 6 to support the boom 5 of the offshore crane 71, thereby constituting an offshore crane layout structure on an oil drilling platform.

[0035] Since the platform space on the drilling platform 7 is expanded by installing the extended platform 2 and the extended outer platform 6, the crawler crane 52 is installed on the extended platform 2 and the drilling platform 7 through the traveling tracks 51, or the offshore crane 71 is installed on the extended platform 2, and the platform outer anti-sway shelf 3 is installed on the extended outer platform 6 to support the boom 5 of the crawler crane 52 or the offshore crane 71, which solves the problem that the space of the offshore wind power construction platform transformed from the oil drilling platform is small and cannot meet the installation of the crawler crane or the offshore crane.

[0036] The platform outer anti-sway shelf 3 for the main boom of a large crane in the present application includes:

[0037] The support assembly 1 fixedly installed on the extension platform 6 and the headrest assembly fixed on the support assembly 1. The support assembly 1 inclines outwards

[0038] The headrest assembly includes a transition platform 21 fixed to the top of the support assembly 1. An inclined pillar 22 is fixedly installed on the transition platform 21 in an inclined manner. The inclined pillar 22 inclines inwards, contrary to the outward inclination of the support assembly 1. The middle parts between the inclined pillars 22 are fixedly connected and strengthened by a connecting rod 23, and the top parts between the inclined pillars 22 are fixedly connected and strengthened by a reinforcing plate 24.

[0039] A headrest platform 25 is fixed on the top parts of the inclined pillar 22 and the reinforcing plate 24. A limiting block 26 is fixed on the inner surface of the headrest platform 25. The limiting block 26 is made of an elastic rubber plate. The four limiting blocks 26 are distributed at intervals on the headrest platform 25 for contacting and placing the boom 5.

[0040] When the crawler crane 52 or the offshore crane 71 needs to be stabilized under the influence of sea breeze on the drilling platform 7, the boom 5 of the crawler crane 52 or the boom 5 of the offshore crane 71 is placed on the headrest platform 25 at the top of the support assembly 1. At this time, the boom 5 contacts the four limiting blocks 26 distributed at intervals on the headrest platform 25. Since the limiting block 26 is made of an elastic rubber plate, flexible damping contact between the boom 5 and the headrest assembly is realized, solving the problem that rigid contact between the rigid parts of the boom support structure and the boom is likely to cause wear.

[0041] The support assembly 1 includes four outwardly inclined inclined columns 11. A horizontal support 12 for fixedly connecting and strengthening between the inclined columns 11, a long diagonal brace 13 for fixedly connecting and strengthening between the upper horizontal supports 12, and a short diagonal brace 14 for fixedly connecting and strengthening between the lower horizontal supports 12. The transition platform 21 is fixed to the top of the inclined columns 11.

[0042] The extension platform 6 includes a platform panel 61 fixed to the drilling platform 7. An inclined support 63 is fixed to the lower part of the platform panel 61. The inclined support 63 in an inclined state fixedly connects the platform panel 61 to the drilling platform 7. The inclined columns 11 of the support assembly 1 are fixed to the platform panel 61 of the extension platform 6. The extension platform 6 can be fixed to the bottom of the support assembly 1 to form an integral whole, enabling the extension platform 6 to be matched with the support assembly 1 and making the extension platform 6 form a part of the support assembly 1.

[0043] A vertical support 34 is fixed between the middle part of the inclined support 63 and the middle part of the bottom surface of the platform panel 61. The inclined columns 11 are located on the platform panel 61 at the top of the vertical support 34. A triangular plate 32 is fixed to the top of the platform panel 61 and the inclined support 63 for strengthening.

[0044] A horizontal rod 35 is fixed between the middle part of the inclined support 63 and the drilling platform 7; a triangular plate 32 is fixed between the platform panel 61 and the top of the inclined support 63 for reinforcement. The inclined column 11 is located on the platform panel 61 at the top of the inclined support 63.
