Abstract
The utility model relates to a complete machine hanger with an adjustable center of gravity, which comprises a lifting beam, wherein a lifting point is arranged on the lifting beam, a movable counterweight body is arranged at one end of the lifting beam and a lifting point component is arranged on the lifting beam. When a work piece in a certain state is lifted, the center of gravity of the work piece is fixed, and the position of the counterweight body and the position of the lifting point at the upper part are adjusted, so that the lifting point on the beam, the center of gravity of the hanger and the center of gravity of the work piece are on the same vertical straight line, as a result, the work piece keeps horizontal when lifted up. When the hanger is applied to lift a complete wind-driven generator, as the lifting point of the complete machine is fixed but some parts are not installed on the complete machine before lifting and transporting during the assembly process, the center of gravity of the complete machine is changed; and the hanger fits the situation by adjusting the position of the counterweight body and the position of the lifting point on the lifting beam. The complete machine hanger with the adjustable center of gravity can reduce the suspension height of an overhead crane, save the cost of corollary equipment, and is significant in practical value and wide promotion.
Description
Technical field
The utility model relates to a kind of suspender, is specially a kind of later-model large-scale wind driven generator integral hoisting and hoist tool.Its objective is design one cover center of gravity adjustable suspender, the center of gravity that makes suspender self be consistent by the center of gravity of hanging piece.The present invention is not only applicable to hoisting large-size aerogenerator complete machine, also is applicable to other all centers of gravity of lifting and the skimble-scamble device of the type heart.
Background technology
When aerogenerator is sling, generally can utilize a fine strain of millet formula suspender.As Fig. 4, shown in Figure 5, can find that in use the center of gravity of the center of gravity of suspender self and workpiece is not on same vertical straight line before lifting, suspender and workpiece meeting run-off the straight were controlled and this tilt quantity is very difficult after workpiece was sling.The general length that in use can regulate suspender belt on the suspender makes hanging beam that individual leaning angle is arranged earlier in advance, and behind the workpiece of slinging, hanging beam and workpiece can both keep level.But the length that the bevelled suspender can make the lower end connect with rigging extends, and has increased the height that hangs of overhead traveling crane.Also have, if single suspension centre is used in the hanging beam upper end, just bevelled hanging beam mode is unavailable.Many suspension centres just must be used in hanging beam upper end, and overhead traveling crane hangs height and can increase very big again like this.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of center of gravity adjustable complete machine suspender, and purpose is to make the center of gravity of the center of gravity of overhead traveling crane suspension hook, suspender and workpiece on same vertical straight line.When overhead traveling crane was sling suspender, the hanging beam of suspender was a level like this, and after together slinging with workpiece, hanging beam and workpiece can both keep horizontality.
For achieving the above object, the utility model adopts following technical proposals:
The adjustable complete machine suspender of a kind of center of gravity comprises hanging beam, and hanging beam is provided with suspension centre, is provided with position-movable balance weight body at an end of hanging beam, also is provided with the suspension centre assembly on the hanging beam.
Described balance weight body comprises balance weight body outer cover and clump weight, and clump weight is fixed on the balance weight body outer cover, is equipped with roller on the balance weight body outer cover, the matching of the groove of roller and described hanging beam both sides; Be fixed with captive nut on the hanging beam, be installed with screw rod in the captive nut, screw rod links to each other with a handwheel, and screw rod or handwheel are connected with described balance weight body outer cover simultaneously.Described suspension centre assembly be arranged at hanging beam above, the suspension centre assembly is provided with a plurality of hook on hole.
Add the counterweight of one group of adjustable positions in a side of suspender hanging beam, removable suspension centre of design on the hanging beam of suspender.When hanging the workpiece of a certain state, the center of gravity of this workpiece is definite, regulates the position of counterweight and top suspension centre, and the center of gravity that makes suspension centre on the beam, suspender center of gravity and workpiece is on same vertical straight line, and when slinging workpiece, workpiece will keep level like this.When this suspender uses the aerogenerator unit assembling of ship machinery, because the suspension centre of complete machine is certain, but in the stack-mounted process, may has some parts on the complete machine and also install and just want handling, change has just taken place in the center of gravity of complete machine like this.Position by regulating suspension centre on counterweight and the hanging beam just scalable goes out to be fit to this state suspender.
The utility model can lower overhead traveling crane and hang height, saves the cost of corollary equipment, the present invention proposes the adjustable complete machine suspender of center of gravity, the meaning that very important practical value is arranged and extensively promote.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the adjustable complete machine suspender of a kind of center of gravity mainly is made up of hanging beam 2, suspension centre assembly 11 and balance weight body 10.Hanging beam 2 lower ends also are provided with three suspension centres, suspension centre assembly 11 be arranged at hanging beam 2 above, suspension centre assembly 11 is provided with a plurality of hook on hole.
As Fig. 2, shown in Figure 3, be provided with position-movable balance weight body 10 at an end of hanging beam 2, balance weight body 10 comprises that clump weight 3, balance weight body outer cover 1, roller 5, captive nut support 7, captive nut, screw rod 6 and handwheel 9 form.At first, the cross-sectional plane of hanging beam 2 is " worker " shape, and both sides have groove.Balance weight body outer cover 1 is located at hanging beam 2 outsides, and a clump weight 3 is respectively assembled by bolt 4 in the outside of the left and right sides of balance weight body outer cover 1, and the inside is equipped with roller 5, and roller 5 matches with the groove of hanging beam 2 both sides.The top welding one captive nut support 7 of hanging beam 2, captive nut is assemblied on the captive nut support 7, and screw rod 6 is assemblied in the captive nut 8, and handwheel 9 is installed on the screw rod 6, also is assemblied on the balance weight body outer cover 1 simultaneously.
