As preferred version, the lifting appliance for hoisting of above-described blade of MW class wind turbine gusset, described suspender lower body lower end is provided with horizontal thread rubber peel.
As preferred version, the lifting appliance for hoisting of above-described blade of MW class wind turbine gusset, the first described suspender upper body is made up of a pair of female bar of the first suspender and the male bar of the first suspender that can be mutually nested.
As preferred version, the lifting appliance for hoisting of above-described blade of MW class wind turbine gusset, the second described suspender upper body is made up of a pair of female bar of the second suspender and the male bar of the second suspender that can be mutually nested.
As preferred version, the lifting appliance for hoisting of above-described blade of MW class wind turbine gusset, described shackle is U-shaped shackle.
The suspender of the blade of MW class wind turbine gusset lifting use that the utility model provides, be characterized in: overall appearance is " 8 " font, suspender body divides the first suspender upper body, the second suspender upper body and suspender lower body, the first suspender upper body can be mutually nested with the second left and right part in upper body, suspender upper body, and the top after nested is connected by shackle; Suspender lower body is provided with cross-tie steelframe and horizontal thread rubber peel simultaneously.Adopt the flexible connection of adapter shaft, can make that suspender is freely opened, closure, suspender is opened to be put into and is hung while lifting on gusset, and suspender can step up the object of slinging automatically.
The suspender of the blade of MW class wind turbine gusset lifting use that the utility model provides, suspender is provided with upper body and lower body, and Yi Ce upper end, upper body can embed opposite side, and can connect by shackle, and shackle can be suspended on lifting machinery equipment.
The suspender of the blade of MW class wind turbine gusset lifting use that the utility model provides, suspender lower body is provided with cross-tie steelframe, and supporting steel frame has certain length along length of blade direction, and width and main stickup angle are wide, can stablize and clamp blade gusset, keep lifting stable.
The suspender of the blade of MW class wind turbine gusset lifting use that the utility model provides, suspender lower body cross-tie steelframe and suspender are provided with horizontal thread rubber bottom, when lifting, horizontal thread contacts with gusset inside face with the main stickup of gusset angle, while remaining on lifting, steadily, can not slide.
Beneficial effect: compared to the prior art the suspender of the blade of MW class wind turbine gusset lifting use that the utility model provides has the following advantages:
The suspender that the utility model provides, designs and produces according to constructional feature and the installation requirement of blade of wind-driven generator " gusset ".In the time of blade production period lifting " gusset ", suspender is suspended to above the suspension rod under workshop " driving ", suspender is opened under the main stickup angle that is put into gusset, ensure that so erose gusset can be steady in the time of lifting, and the special construction of suspender can not produced and damage to gusset in the time of lifting; The mounting structure of suspender itself, even if ensure gusset being perfectly safe in hoisting process---in the time that fracture suddenly occurs suspender main chain spindle, the gusset being lifted still can not be jammed and can fall.
The suspender of blade of MW class wind turbine gusset that the utility model provides lifting use compared with prior art, reasonable in design, workable, equipment cost is low, can save time of setting up, work efficiency is higher, and can actv., well protection is by lifting gusset; Firm when lifting, safety good, have wide range of applications.
