Technical field
The utility model relates to the lifting of using in the cabin of a kind of hoisting device, particularly wind power generating set and safeguards the hoisting device of usefulness.
Technical background
Because the cabin of most of wind power generating set overhead has seventy or eighty meters high, lifting and maintenance are all inconvenient, need a kind of hanging apparatus can do maintenance again in the cabin from ground lifting tool and part the time.Because blower fan generator unit structure layout, the cabin of wind power generating set is narrower and small, so debugging, maintenance is all inconvenient.
In the weight-lifting equipment layout of traditional wind-powered electricity generation unit, generally select bridge-type and single spiral arm lifting appliance for use, but in order to reduce the weight in cabin, the space in cabin is seldom the time, bridge-type and single spiral arm all can't move and lift by crane flexibly in the cabin, as the walking spiral arm of patent ZL200920139888.1 hang base material platform, the moving 360 degree spiral arms of ZL200920089576.4 two-track hang all and can't satisfy whole requirements, and the obstacle of the spiral arm of patent 92202688.2 box electric block arm hoists in can't hiding in the spiral arm rotary area.
The utility model content
The purpose of this utility model be to provide a kind of can be simple and reliable in small space, can hide obstacle in the front arm rotary area to the compact device of zone lifting in addition.
The purpose of this utility model is achieved through the following technical solutions: a kind of MW class wind turbine bispin arm hanging apparatus, be fixed with the rocking arm permanent seat in the cabin of wind power generating set; the rocking arm permanent seat is connected with a rocking arm that can rotate around bearing pin by a bearing pin; the front end at rocking arm is equipped with an electric block; its characteristics are: described rocking arm is two joints; be respectively front arm and rear arm; front arm connects with the rear arm rotation by the front arm axle, what front arm and rear arm were combined to form two saves folding pair of rocker structure; Electric block is installed in the outer end of front arm, and electric block is used for lifting by crane object in ground or cabin; On front arm and rear arm two joint rocking arms, be respectively equipped with the rocking arm damper regulator; Wherein, the rear arm damper regulator is installed on the rear arm permanent seat, and rear arm is played shock damping action; The front arm damper regulator is installed on the rear arm, and the front arm damper regulator stops the relative motion of front arm and rear arm.Described rocking arm damper regulator comprises a damping mount pad, the damping mount pad is fixed on rear arm permanent seat or the rear arm, one control apparatus is arranged in the damping mount pad, the adjust bar front of control apparatus is with a damping sliding sleeve, the outer ring of damping sliding sleeve is enclosed within the damping sliding sleeving hole of damping mount pad, and damping sliding sleeve and damping mount pad are sliding connection; Be inserted with the adjust bar of control apparatus in the endoporus of damping sliding sleeve; Leading section at the damping sliding sleeve is fixedly connected with the damping material piece.
Characteristics of the present utility model are:
Change rocking arm into two joint rocking arm array configurations, two rocker structures of being made up of front arm and rear arm are collapsible respectively, can escape the zone of front arm scanning after folding, to the cabin space advantageous particularly of narrow and small wind-powered electricity generation unit.
