Abstract
The invention discloses a variable pitch gearbox hoisting tool for a wind generating set. The variable pitch gearbox hoisting tool comprises a sling frame structure, a first fixing piece, a second fixing piece and a handrail. The sling frame structure is a C-shaped structure. The first fixing piece and the second fixing piece are arranged at the two ends of the top of the sling frame structure respectively. The second fixing piece penetrates the top of the sling frame structure. The second fixing piece and the top of the sling frame structure are detachably arranged. The handrail is arranged at the bevel of the bottom of the sling frame structure. The handrail is of an A-shaped structure. A fixing block is arranged at the open end of the bottom of the sling frame structure, and the bottom of the fixing block is connected with a lifting hook. A tool structure capable of easily installing a variable pitch gearbox deep into a hub cavity is designed. A hanging rope can be replaced according to variable pitch gearboxes of different weights, and therefore one sling frame structure can be suitable for installing the variable pitch gearboxes of different weights, and the purpose of saving the installing cost input is achieved.

The present invention is achieved through the following technical solutions: a kind of wind generating set pitch control gear case hoisting fixture, comprise suspender frame structure, first firmware, second firmware and handrail, described suspender frame structure is C character form structure, described first firmware and the second firmware are arranged at two ends, suspender frame structure top respectively, described second firmware runs through suspender frame structure top, and the second firmware and suspender frame structure top are detachable setting, described handrail is installed on knuckle place bottom suspender frame structure, and handrail is A character form structure, described suspender frame structure bottom open end is provided with fixed block, a suspension hook is connected with bottom described fixed block.
Further for realize the present invention better, be arranged to following structure especially: the lower section of described second firmware is also arranged porose, described second firmware is arranged on suspender frame structure top open part and is threaded with suspender frame structure and arranges.
Further for realize the present invention better, being arranged to following structure especially: described first firmware is arranged on knuckle place, suspender frame structure top, being threaded between described first firmware and suspender frame structure top or in being wholely set.
Further for realize the present invention better, be arranged to following structure especially: described suspender frame structure, handrail and fixed block are one-body molded.
The present invention compared with prior art, has the following advantages and beneficial effect:
The present invention overcomes the weak point of above-mentioned technology, and designs a kind of tool structure that easily variable propeller gearbox can be arranged on depths in wheel hub cavity; And can change lifting rope according to the Different Weight of variable propeller gearbox, make to utilize a kind of suspender frame structure can adapt to the installation of the variable propeller gearbox of multiple Different Weight, avoid occurring that a kind of suspender frame structure only can adapt to the situation generation of the variable propeller gearbox of single weight, thus play the object of saving cost of installation and dropping into.
Suspender frame structure of the present invention, handrail and fixed block adopt integrated formed structure, further can strengthening the intensity of frock, avoiding occurring safety misadventure when lifting.
Second firmware of the present invention and suspender frame structure adopt detachable connection to arrange, when lifting, because of varying in weight of variable propeller gearbox, and conveniently carry out the replacing of lifting rope, and in bottom providing holes, cross bar can be interted, make to form T-shaped structure between itself and the second firmware, thus further form a kind of safety measure, avoid occurring safety misadventure.
