Description
Technical field
What the present invention relates to is a kind of large-scale superelevation lifting altitude crane barge installed for ocean engineering.
Background technology
Crane barge is the important equipment for ocean engineering installation and lifting and installation, be widely used in the installation of offshore platform, build in operation, be particularly applied to ocean engineering hoisting operation field, as the installation of platform, the maintenance of derrick, the installation etc. of offshore wind power equipment; Meanwhile, crane barge is also the important equipment that seabed is installed.Existing crane barge is divided into coastal waters crane barge and deep ocean work crane barge according to purposes, coastal waters crane barge hoisting capacity is little, between general 1000 ~ 3000 tons, installation crane barge hoisting capacity is also little, be mainly used in the installation of port machinery equipment, and the hoisting capacity of deep ocean work is relatively large, because the hoisting capacity of installing crane barge directly determines the construction ability of this crane barge.At present, the crane barge hoisting capacity of largest domestic is 7500 tons, crane barge hoisting capacity is in the world also in equal rank, but along with the development of ocean engineering, it is trend that crane barge maximizes, sea frock is standby along with keeping the large-scale development, therefore, installing area at sea, original crane barge can not adapt to the trend that ocean engineering maximizes, installation exercise efficiency is too low, seriously constrain the development of ocean engineering, and the present invention adapts to the trend that ocean engineering maximizes just, invent the crane barge that hoisting capacity is 3000 tons of lifting altitudes 165 meters, tens meters are exceeded than existing crane barge ability, greatly expand the scope of work of crane barge, that originally cannot install can install now, also substantially increase the efficiency of installation simultaneously, reduce the cost of installation, obtain larger economic benefit.
Existing crane barge mainly contains two large classes: fixed arm posture crane barge and swinging crane barge, fixed arm posture crane barge comprises jib, support, Shears etc.The lifting power of fixed arm posture crane barge is large, and structure stress form is good, and use relatively more extensive, and crane barge is not high due to lifting altitude, applies extensive, when equal hoisting capacity, the deadweight of fixed arm posture crane barge is lighter, and safety of structure is high.Therefore the crane barge that crane barge design adopts fixed arm posture, particularly coastal waters to install mostly mostly adopts fixed arm posture, the crane barge of this form, and lifting power is larger, and stress form is good, ensure that the stability of structure.Therefore, current crane barge adopts fixed arm posture crane barge to carry out operation usually, particularly ocean engineering installs crane barge, installation exercise is to liking, need to provide huge lifting power to tear steel plate, again its segmentation is installed, this needs ocean engineering to install the safety of this body structure of crane barge, must ensure that crane barge has enough lifting altitudes under the prerequisite of enough hoisting capacities, and crane barge will possess the hoisting capacity of super large, platform leg segmentation installed, now the lifting altitude of crane barge seems and is even more important quickly.
Along with weight equipment technology in ocean develops rapidly to maximization, high-technicalization direction, heavy-duty floating crane is also to maximization, high efficiency development, to adapt to the needs of Overseas Development situation, development of new techniques, existing heavy type is installed crane barge schedule work and is revealed following features: first: crane barge lifting altitude is huge, second: crane barge hoisting capacity is huge, 3rd: crane barge operating load is severe, the 4th: crane barge operating efficiency is high, disposable for spud leg segmentation installation can at sea come up by requirement; 5th, crane barge safety is high, and crane barge structure not only will bear huge hoisting capacity, and will realize when lifting the verting of lift heavy, the action such as to stand up, and realizes ocean engineering installation exercise.Therefore, it is high that heavy-duty floating crane must meet structural strength, and provide load large, stability safety is high, and heavy-duty floating crane must meet under above requirement condition, and deadweight is light as much as possible, reduces productive costs, improves the commercial efficiency of crane barge.
