Description
Technical field
The present invention relates to blade of wind-driven generator hoisting technology field, more particularly to a kind of fan blade is put down to hang and change and hung
Tool.
Background technology
In order to which the sustainable development of the energy and environmental protection, low-carbon economy, the development of clean energy resource are imperative.Wind-powered electricity generation is done
For the pith of clean energy resource, there is the characteristics of green, safe, be widely used and develop at home in recent years.Blade
It is the critical component of blower fan, because the limitation of structure type must use composite, exposure operates in the air throughout the year for it, easily
Aging, damage.At present, the common method for changing blade is installed or repaired in blower fan operation, is essentially all the leaf blower fan
Piece gets off with wheel hub integral demounting, and impeller is installed return fan again after blade is finished changing on ground, because fan blade length is more next
Bigger, more in 30-70m, Renewal process needs large-scale equipment, broad place, and maintenance replacing difficulty is big, cost is high, the time
It is long, it is impossible to fast quick-recovery unit generation, particularly also so operated when single branch blade damage, then it is more aobvious to waste time and energy.In addition,
In special Venue Operations, fan blade difficulty is changed in such as mountain region, sea will be bigger.In addition, significantly due to wind
Machine blade is irregular-shaped objects, and traditional suspender lifting operation is difficult manipulation, and stability and security are poor, although relevant
Also occur some modified suspenders in technical literature, but still there is it is complicated, cost is high, cumbersome, work effect
The low technological deficiency of rate.
The content of the invention
The technical problems to be solved by the invention are just to provide that a kind of fan blade is flat to hang and changes suspender, show to overcome
There is in technology, place high to equipment requirement take big, operation is wasted time and energy, and traditional suspender task difficulty is big, security and stably
The technological deficiencies such as property difference.
The technical solution adopted for the present invention to solve the technical problems is：
Fan blade is flat to hang and changes suspender, including chain sling device, is lifted on the T-shaped beam of chain sling device lower end, installed in T-shaped
The suspender belt of beam bottom, the chain sling device are made up of suspension ring, the chain sling being mounted on suspension ring and suspension hook, and the T-shaped beam includes
Longeron and one end and the crossbeam being connected in the middle part of longeron, one group of take-up and pay-off device, the take-up and pay-off device are respectively provided with longeron both ends
For electric block or bottle gouard moved by hands or one kind of blue bolt is spent, the suspender belt is divided into blade and blade tip suspender belt and hung with blade and blade root
Band, the both ends of leaf tip suspender belt are lifted on the suspension centre of two groups of take-up and pay-off device lower ends respectively, and blade root suspender belt is slided by rotating
Wheel is mounted on the suspension centre of crossbeam lower end.
Further, three chain slings have been mounted on the suspension ring of the chain sling device, one is respectively provided with the longeron both ends of T-shaped beam
Individual longeron hanger, crossbeam hanger is provided with longeron front of motor on crossbeam, three chain sling lower ends respectively with longeron hanger and
Crossbeam hanger top lifts, and two groups of take-up and pay-off devices are lifted on two longeron hanger bottoms respectively, and crossbeam hanger bottom passes through rotation
Turn pulley and mount blade root suspender belt.
Further, it is equipped with the hanging hole no less than one in longeron hanger and crossbeam hanger bottom.
Further, brace is provided between longeron and crossbeam, crossbeam is multistage docking structure.
As preferable, two groups of suspender belts are Flat belt, bandwidth 200-400mm, in use, blade root suspender belt is around leaf
Piece blade root one lifts after enclosing.
Having the technical effect that acquired by the present invention：
1st, because the present invention includes chain sling device, the T-shaped beam for being lifted on chain sling device lower end, hanging installed in T-shaped beam bottom
Band, the chain sling device are made up of suspension ring, the chain sling being mounted on suspension ring and suspension hook, and chain sling device of the present invention can pass through tune
Whole suspension hook is hooked on cuff link position different on chain sling, to adjust each edge lengths of chain sling, plays a part of adjusting suspended object center of gravity；
Because the T-shaped beam includes longeron and one end and the crossbeam being connected in the middle part of longeron, T-shaped girder construction of the invention can reduce tradition
Damage of the suspender in hoisting process to blade and blade tip；Due to being respectively provided with one group of take-up and pay-off device, the receipts at longeron both ends
Actinobacillus device is electric block or bottle gouard moved by hands or the one kind for spending blue bolt, and of the invention two groups of take-up and pay-off devices pass through adjustment one
The retractable operation of group device, can manipulate and be rotated by hoisting blade, be easy to the dismounting of blade with docking, two groups of wire coiling and releasings
Put while retractable operation, blade one end can be hung by raising or reducing, hung the adjustment of blade levelness；By institute
State suspender belt and be divided into blade and blade tip suspender belt and blade and blade root suspender belt, the both ends of leaf tip suspender belt are lifted on two groups of retractable cables respectively
On the suspension centre of device lower end, blade root suspender belt is mounted on by rotating pulley on the suspension centre of crossbeam lower end, when take-up and pay-off device with
Retractable cable mode adjust leaf tip suspender belt both ends high and low position and drive hung blade rotation when, blade root suspender belt can pass through rotation
Turn the realization of pulley driving hanging object and follow rotation, and adjust automatically gravity balance without impact, simple in construction, manipulation is convenient, real
It is good with property；To sum up, the present invention is applied to the upper air installing of fan blade, changes the operations such as dismounting, and simple in construction, cost is cheap,
It is easy to operate, safety and stability, no place limitation, the various situation operations such as land, marine and mountain region are common to, it is applied widely
It is general.
2nd, due to having mounted three chain slings on the suspension ring of the chain sling device, one is respectively provided with the longeron both ends of T-shaped beam
Longeron hanger, crossbeam hanger is provided with longeron front of motor on crossbeam, three chain sling lower ends respectively with longeron hanger and horizontal stroke
Beam hanger top lifts, and two groups of take-up and pay-off device upper ends are lifted on two longeron hanger bottoms respectively, and crossbeam hanger bottom passes through
Rotating pulley mounts blade root suspender belt, and the present invention is rational in infrastructure, and three hangers that three chain slings are correspondingly arranged on T-shaped beam are hung
Dress, hanger is stressed member, and T-shaped beam beam body only plays a supportive role, and product stability is good, securely and reliably.
3rd, due to being equipped with the hanging hole no less than one in longeron hanger and crossbeam hanger bottom, can select as needed
Suitable hanging hole position；Due to being provided with brace between longitudinal and cross beam, crossbeam is multistage docking structure, and of the invention is T-shaped
Girder construction is firm, and crossbeam is multistage docking, can be adapted to the lifting of all size blade, and versatility is good.
4th, because the suspender belt is Flat belt, bandwidth 200-400mm, in use, blade root of the blade root suspender belt around blade
Portion one lifts after enclosing, and can effectively prevent blade injury, lifting is steady, and can effectively tighten up blade and blade root, prevents blade from existing
High-altitude slides, and further improves security.
