Description
Technical field
The utility model relates to support and ship, particularly relates to assembled transport sectional shelf-unit and carrier.
Background technology
Impeller is one of constituent elements of wind power generating set, and be the critical component obtaining wind energy and convert it into mechanical energy, it generally comprises blade and wheel hub.Through people's years of researches and test, be the impeller that sea or land wind power generating set generally all adopt three-vane at present, the sheet number of the blade be namely connected with wheel hub is three.Along with the progressively maximization of wind power generating set, the length of blade of these wind power generating set is usually tens meters of rice even up to a hundred, and therefore, the transport of wind power generating set and installation are than relatively large engineering.
Current wind power generating set generally comprises three types: permanent magnet direct-driven, double-fed type and half direct-drive type, wherein small generator, gear case etc. are arranged in cabin by double-fed type and half direct-drive aerogenerator group, and the electrical generator of permanent magnet direct-drive wind-force generating unit is generally positioned at outside cabin.When installing these wind power generating set, cabin, electrical generator and impeller generally need successively lifting separately to get on to assemble.When wind power generating set is installed at present on land, in order to lift impeller, general employing cloverleaf hanging method, cloverleaf lifting need installation base by wheel hub and three blades assembled good, specifically need when lifting to use two respective independently suspension hooks, wherein first suspension hook connects two suspender belts, these two suspender belts connect the root (part be namely connected with wheel hub) of wherein two blades respectively, the suspender belt of second suspension hook connection is connected near the part of blade tip with the 3rd blade, when lifting, first two suspension hooks promote simultaneously, impeller level is sling, then, second suspension hook declines, first suspension hook continues to promote simultaneously, impeller is made to overturn nearly 90 °, pine second suspension hook afterwards, in place by first hook impeller.
But directly drive in the process of unit at installation sea, contriver finds, for marine unit, what the distant installation project of offshore adopted is jack up ship, and the hull of this ship is with jack up spud leg, and therefore the area on deck is less, there is no enough space assembly cloverleaf impellers, and the main suspension hook of this installation ship is single hook, there is no two independently suspension hooks, so the cloverleaf lifting of impeller can not be realized.
Also a kind of scheme utilizing single hook block dress sea directly to drive unit is had at present, it adopts a word beam or rood beam first to lift the assembly parts of wherein two blades of cabin, electrical generator, wheel hub and three blades as suspender, is lifted separately by the 3rd blade afterwards with another suspender.This Hoisting Program only can adopt a suspension hook, but contriver finds wherein also to there is larger defect in practice: due to cabin, electrical generator, wheel hub and two blades, weight is too large altogether, in order to lift, needing must be larger by the size design of the hanger on wheel hub and engine room foundation, but produces a lot of contradiction between meeting and the former design of wind power generating set like this.Such as wheel hub, the requirement that wheel hub will meet strength at repeated alternation could ensure its service life, if but the hanger larger on wheel hub, its strength at repeated alternation will reduce, according to actual computation, if contriver finds the hanger size added on big hub, the strength at repeated alternation of wheel hub will out of reach requirement, and the strength at repeated alternation of wheel hub to meet the demands be one of them essential condition of wind power generating set design.And for electrical generator, adopt the hanger lifting on electrical generator can cause the distortion of generator amature, affect the air gap of electrical generator, be also unfavorable for the performance ensureing electrical generator.And the hanger larger on engine room foundation can be subject to the restriction in space in cabin, easily cause and mutually interfere with miscellaneous part in cabin.For this reason, contriver contemplates a kind of new Hoisting Program also do not applied for a patent and lifts to utilize single suspension hook: first lift once the assembly parts of cabin and electrical generator, then the assembly parts of wheel hub and two blades is lifted once, once to the 3rd leaf blade hanging finally.
But, in order to coordinate this new Hoisting Program, just need before this wheel hub and two blades to be carried out assembled and transport.Because the design of this Hoisting Program itself is new, do not possess the assembled of this function and transport support in the prior art.
