Abstract
The invention discloses a process for installing an impeller assembly elephant foot balance bracket of an offshore wind power field. The process comprises the following steps of: putting a base at first: then, installing balance elephant feet: respectively inserting a first balance elephant foot 3, a second balance elephant foot 4 and a third balance elephant foot 5 in the base 1, wherein the depth is not less than 2 m; after installing the balance elephant feet, assembling impellers, and, in the event of assembling the impellers, connecting a hub 2 to the base 1 by using a bolt; and finally, assembling blades: respectively assembling a first blade 6 on the first balance elephant foot 3 and assembling a third blade 8 right above the third balance elephant foot 5 in turn, and finally, assembling a second blade 7 on the second balance elephant foot 4. The process disclosed by the invention has the advantages of being high in working efficiency, smart in structure, low in requirement of operation platform space, simple for operation and strong in bearing capability.
Description
Technical field:
The present invention discloses a kind of mounting process of balance bracket, and particularly a kind of marine wind electric field impeller assembling resembles the mounting process of leg balance bracket.
Background technique:
Marine intertidal belt wind electric field blower equipment is installed at present, and feasible scheme is the lifting that distributes.Wherein wheel hub and three blades are in the assembling of operating platform deck plane level, and basic order is first positioning and fixing wheel hub, and three blades are installed then one by one.But because blade is elongated, when mounting blades, have serious eccentric moment, the way of taking usually is a bed hedgehopping intensity foam plate below the position of the inclined to one side afterbody of blade center of gravity.This method is brought following two difficult problems: 1) the operating platform area is enough big, places the high tenacity foam plate to guarantee enough spatial position; 2) along with the quick increase of offshore wind farm type, blade dimensions, weight are increasing, and present existing high tenacity foam can't carry the weight of big type blade.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency; A kind of balance blade deadweight that is used for is provided; Thereby reduce requirement, and a kind of marine wind electric field impeller assembling that adapts to the growth requirement of big type gradually resembles the mounting process of leg balance bracket to the operating platform area.
The object of the invention is realized through following technological scheme: a kind of marine wind electric field impeller assembling resembles the mounting process of leg balance bracket; May further comprise the steps: at first lay pedestal: at first as requested pedestal is placed on specified position, and is welded in the construction equipment deck plane; Balance is installed then resembles leg: respectively first balance is resembled leg 3, second balance and resemble leg 4 and the 3rd balance and resemble leg 5 and insert pedestals 1, and the degree of depth is not less than 2 meters; Balance resembles leg and installs back assembling impeller, during the impeller assembling, earlier wheel hub 2 usefulness bolts is connected on the pedestal 1, guarantees during the location that two blades are positioned at that first balance resembles leg 3 and the 3rd balance resembles directly over the leg 5; Assemble blade at last: respectively first blade 6 is assembled in first balance successively and resembles on the leg 3, the 3rd blade 8 the 3rd balance is resembled directly over the leg 5, at last second blade 7 is assembled in second balance and resembles on the leg 4.
The advantage that the present invention compared with prior art has is: adopt Design Of Steel Structure to make, boundary dimension is little, and is little to the operating platform spatial requirement; Simple to operate; After only need pedestal being placed on specified position, respectively three balances being resembled leg and insert pedestal, can carry out the impeller assembly operation; Bearing capacity is strong, can satisfy the existing various type demands of wind energy turbine set.
Description of drawings:
Fig. 1 is a use schematic representation of the present invention;
Label among the figure: 1-pedestal, 2-wheel hub, 3-first balance resemble that leg, 4-second balance resemble leg, 5-the 3rd balance resembles leg, 6-first blade, 7-second blade, 8-the 3rd blade.
Embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show the mounting process that a kind of marine wind electric field impeller assembling of the present invention resembles the leg balance bracket like Fig. 1, may further comprise the steps: at first lay pedestal: at first as requested pedestal is placed on specified position, and is welded in the construction equipment deck plane; Balance is installed then resembles leg: respectively first balance is resembled leg 3, second balance and resemble leg 4 and the 3rd balance and resemble leg 5 and insert pedestals 1, and the degree of depth is not less than 2 meters; Balance resembles leg and installs back assembling impeller, during the impeller assembling, earlier wheel hub 2 usefulness bolts is connected on the pedestal 1, guarantees during the location that two blades are positioned at that first balance resembles leg 3 and the 3rd balance resembles directly over the leg 5; Assemble blade at last: respectively first blade 6 is assembled in first balance successively and resembles on the leg 3, the 3rd blade 8 the 3rd balance is resembled directly over the leg 5, at last second blade 7 is assembled in second balance and resembles on the leg 4.
The present invention resembles the design and use of leg frock through balance; Having now under the marine intertidal belt wind electric field construction equipment situation in short supply; Solve Fan Equipment the harsh demand to large space, shallow draft construction equipment has been installed, also adapted to the fast-developing demand of offshore wind turbine type.
