Abstract

The invention relates to a hoisting device used according to needs and used in a wind power unit cabin. The hoisting device mainly comprises three parts including a crane support, a fixed type electric block and a temporary hoisting system. The crane support is composed of supporting columns, transverse beams and longitudinal beams. The fixed type electric block is installed on one transverse beam of the crane support. The temporary hoisting system is composed of a walking trolley on the longitudinal beams installed on the two sides of the crane support, a dual-purpose cross beam with the two ends fixed to the walking trolley and a hand-pushing monorail trolley and chain block combination installed on the dual-purpose cross beam. The hoisting device used according to the needs can meet the requirement for daily maintenance and can also meet the requirements for maintaining a yaw drive and other heavy components. The impact of swinging of the electric block on the crane support and a cabin cover is reduced by adopting the fixed type electric block and eliminating a travelling crane frame, and the stability and safety of the unit are improved.

Description

Boom hoisting in the Wind turbines cabin of a kind of on-demand use
Technical field
The present invention relates to boom hoisting in a kind of cabin in Large-scale Wind Turbines.
Background technology
In Large-scale Wind Turbines, carry out in cabin safeguarding that required crane structure mainly uses mono beam overhead crane in bridge type.Mono beam overhead crane in bridge type is made up of crossbeam of driving a vehicle, the Electric Chain Blocks of band dolly, driving longeron and Crane Rail, and during use, the roller of driving is walked on long rails, and electric block can be with transverse shifting.The parts needed repairing are winched to thing hole in cabin and are down to ground by electric block, need the most fixing when electric block quits work.The structure using mono beam overhead crane in bridge type form is relative complex, driving frame and electric block are the most removable, during fan operation, rocking of electric block drive chain case can produce impact to driving frame, driving frame produces impact to crane support and cabin, miscellaneous part in cabin can be clashed into when driving frame and electric block are fixed unreliable, produce potential safety hazard.
Summary of the invention
In order to the mono beam overhead crane in bridge type cost overcoming existing use driving frame is high, the defect of the relative complex instability of structure, the invention provides boom hoisting in the Wind turbines cabin of a kind of on-demand use, both the needs of regular maintenance can have been met, it is possible to meet the needs safeguarding the heavier parts such as driftage driving.
The technical solution adopted for the present invention to solve the technical problems is: this boom hoisting mainly includes crane support, fixing type electric calabash, three parts of interim tackling system, wherein crane support is made up of the pillar being arranged in cabin, transverse beam and longitudinal beam, fixing type electric calabash is arranged in the transverse beam of crane support, and the dual-purpose crossbeam that interim tackling system is fixed on walking dolly by the walking dolly being arranged on the longitudinal beam of crane support both sides, two ends, the hand push monorail trolley being arranged on dual-purpose crossbeam and chain block form.
Described dual-purpose crossbeam is fixed with crane support and engine room cover during regular maintenance, is fixed on walking dolly during safeguarding heavier parts.
Described walking dolly, hand push monorail trolley and chain block combination can utilize fixing type electric calabash to assemble in being lifted to cabin during safeguarding heavier parts temporarily, in order to remove after maintenance.
By boom hoisting in the Wind turbines cabin of employing a kind of on-demand use of the present invention, when heavier parts safeguarded by needs, can complete the dismounting of parts by assembling interim tackling system, fixing type electric calabash completes the lifting of parts.Owing to eliminating driving frame and the track of driving frame walking, making crane support structure be simplified, maintenance cost reduces, simultaneously because use fixing type electric calabash, reduce electric block and rock the impact to crane support and engine room cover, improve stability and the safety of boom hoisting.
Accompanying drawing explanation
Accompanying drawing be a kind of on-demand use Wind turbines cabin in the structural representation of boom hoisting.
In figure: 1, pillar;2, walking dolly;3, longitudinal beam;4, fixing type electric calabash;5, transverse beam;6, dual-purpose crossbeam;7, hand push monorail trolley and chain block combination.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Figure shows the structure of boom hoisting in the Wind turbines cabin of a kind of on-demand use, mainly include crane support, fixing type electric calabash 4, interim three parts of tackling system, wherein crane support is by the pillar 1 being arranged in cabin, transverse beam 5 and longitudinal beam 3 form, fixing type electric calabash 4 is arranged in the transverse beam 5 of crane support, interim tackling system is by the walking dolly 2 being arranged on crane support both sides longitudinal beam 3, two ends are fixed on the dual-purpose crossbeam 6 on walking dolly 2, it is arranged on the hand push monorail trolley on dual-purpose crossbeam 6 and chain block combination 7 composition.
In the case of regular maintenance, safeguard articles for use by fixing type electric calabash 4 lifting.When needing to safeguard heavier parts, by fixing type electric calabash 4, walking dolly 2, hand push monorail trolley and chain block are combined 7, and new parts and maintenance tool are lifted in cabin.Walking dolly 2, hand push monorail trolley and chain block combination 7 belong to portion's set of on-demand use, are placed at ordinary times in wind field tool crib, and a wind field only need to configure 1 to 2 set.Dual-purpose crossbeam 6 makes to be fixed by bolts on the longitudinal beam 3 of crane support when dispatching from the factory, and is connected fixing with engine room cover by resilient support simultaneously.When removing the parts needing to safeguard, remove the bolt that dual-purpose crossbeam 6 is connected with engine room cover and pillar 1 simultaneously, crane support longitudinal beam 3 is installed walking dolly 2, dual-purpose crossbeam 6 two ends are fixed on walking dolly 2, then hand push monorail trolley and chain block are combined 7 to be arranged on below dual-purpose crossbeam 6, an interim crane can be formed.
The parts using interim crane that needs are pulled down replacing winch near fixing type electric calabash 4, then new parts are winched to installation site install, after installing new parts, with interim crane, the part pulled down is transported to the position that fixing type electric calabash 4 can be lifted by crane, then portion's set of on-demand use is removed, dual-purpose crossbeam 6 is reduced to fixed form, finally utilizes fixing type electric calabash 4 that set, maintenance tool and the part removed of on-demand use are winched to ground.
Although through the present invention is described in conjunction with specific embodiments, for the art skilled person, the replacement made according to mentioned above, revising and will be apparent from change.Therefore, in such replacement, when modifications and variations fall in the spirit and scope by the claims of the present invention, it should be included in the present invention.
