Due to girder 7 is followed successively by into first horizontal segment, tilting section and the second horizontal segment, and first on L along its length
The height of horizontal plane is less than the second horizontal plane, and first horizontal segment is connected by tilting section obliquely and the second horizontal segment, so
On being placed in first horizontal segment after L beams turnover panel 2, the upper level and the upper level of the second horizontal segment of L beams turnover panel 2 are big
Cause unanimously, to be so advantageous to the steady placement of wind electricity blade, add security, while the presence of tilting section, be used to set just
The mounting groove of installation elevating ram 6 is put, elevating ram 6 is turned into concealed oil cylinder, at work, its expansion link is located at wind to oil cylinder
The lower section of electric blade, avoid the both sides of its face blade, make it is large-sized, or even be wider than the blade of width of the carbody can also be by
Transport, hydraulic jack are connected away from L beams turnover panel horizontal segment H with vertical section connecting portion one end with L beam turnover panel V horizontal segments, are distinguished
The vertical section of L beams is connected directly between in expansion link in the prior art, so that flexible stroke shortens dramatically, so as to improve
Stability, add security.Elevating ram 6 is when being slant setting simultaneously, can accomplish with tilting section it is substantially vertical, with reference to master
Beam tilting section and the longitudinal section of first horizontal segment and the second horizontal segment junction are highly designed, and the structural strength in the portion is greatly increased
By force, security is added.
The setting of the articulated section 5 of the present invention simultaneously, the relatively conventional frock fulcrum of hinged-support move forward, such as Fig. 1, shown in 5,
It is not located at L beam turnover panel vertical sections V underface, but stands away, is dramatically increased with the distance of turnover panel counterweight 1, so
In lifting, due to lever principle, it is only necessary to which the weight of the turnover panel counterweight 1 of small weight can be completed to lift, traditional frock fortune
Defeated 2.5 megawatts 45.3 meters, the wind electricity blade turnover panel for the wind electricity blade that 10 tons of weight needs 8 tons of counterweight, hinged-support reach end blocking
Counterweight only need 2 tons of counterweights, save the energy, simultaneously because balance weight reduce, also improve balance and security.
For hydraulic system, traditional hydraulic station is to move axial axis plug pump, the hydraulic power of output by engine direct tape splicing
It is the throttle size control by engine, thus the oil pressure exported is variable amount of, so as to which the lifting of fan blade, revolution and change oar are fast
It is slow indefinite thus next difficult to conveyer belt.It is that engine 402 drives generator 403 to generate electricity using Novel hydraulic station, drive motor
Hydraulic power is provided by motor driven axial direction axle plug pump, the power is quantitative, so that the lifting of fan blade, revolution and change oar are more
It is stable.
The control stick of operating system is located at the front end of the horizontal segment of girder second, adds the simplicity of operation, and by passing
The multiple directional control valve of system frock is replaced with Electromagnetic Control multiple directional control valve 406, it is possible to achieve Remote controls, and adds operation
The security of work, is mounted with synchronization on the fluid pressure line of elevating ram 6,408 and divides combiner valve, synchronous valve-divide combiner valve
Two/hydraulic motor is controlled to make it keep synchronized to reinstall rotation mechanism, elevating ram 6 in hydraulic synchronous system, upper dress becomes oar and returned
Rotation mechanism with addition of balanced valve, can prevent big chamber in-line rapid decompression from causing oil cylinder to decline；With prevent load inertia from leading
Cause that oil return speed is too fast causes danger.It is achieved thereby that the lifting stability of oil cylinder.
During work, start engine by driven by engine electrical power generators, then close hydraulic motor earth leakage protective device,
Motor connection axial direction plunger pump provides hydraulic power, and plunger pump promotes hydraulic oil to enter hydraulic pressure seamless steel pipe, hydraulic pressure seamless steel pipe
Electromagnetic Control multiple directional control valve is connected by high pressure consistent lubricant pipe.
When carrying out left and right revolution operation, operation handle C is promoted, hydraulic oil is entered the high pressure consistent lubricant pipe of connection, by hydraulic pressure
Flexible pipe enters the hydraulic pressure seamless steel pipe fixed, welds three-pronged connector in the end of hydraulic pressure seamless steel, passes through high pressure consistent lubricant Guan Lian
Two slew gears of three-pronged connector and lower dress are connect, so as to drive the left and right of whole frock to turn round.
When carrying out lift operation, promote operation handle B hydraulic oil to enter the high pressure consistent lubricant pipe of connection, entered by high pressure consistent lubricant pipe
Enter the hydraulic pressure seamless steel pipe fixed, synchronous valve is connected to high pressure consistent lubricant pipe again in the end of hydraulic pressure seamless steel pipe, in synchronization
There is high pressure consistent lubricant pipe 13 to connect between valve and elevating ram balanced valve, so as to the flexible wind electricity blade of realizing for promoting elevating ram
Lifting.
When become oar operation, the high pressure consistent lubricant pipe of operation handle A hydraulic oil connection is promoted, is entered by high pressure consistent lubricant pipe solid
The hydraulic pressure seamless steel pipe set, the two change oar turn-around machines filled are connected to high pressure consistent lubricant pipe in the end of hydraulic pressure seamless steel pipe
Structure, so as to realize the change oar of wind electricity blade.
