Accompanying drawing explanation
Fig. 1 is a kind of adjustable inner hole hanger structure of the utility model figure;
Fig. 2 is that a kind of adjustable inner hole suspender of the utility model bearing plate stretches out the constructional drawing under state;
1, lifting lug device 11, hanger 12, hanger handle 13, hanger connecting panel 2, support 21, support handle 22, supporting plate 23, fixed link 24, adapter plate 241, adapter plate bearing pin 25 guard shields 3, derricking gear 31, suspension rod 311, self-locking device 32, control desk 33, bearing plate 331, bearing plate bearing pin 332, chassis bearing pin 34, chassis.
The specific embodiment
As depicted in figs. 1 and 2, adjustable inner hole suspender, is comprised of lifting lug device 1, support 2 and derricking gear 3.Lifting lug device 1 is comprised of hanger 11, hanger handle 12 and hanger connecting panel 13.Support 2 is comprised of support handle 21, supporting plate 22, fixed link 23, adapter plate 24, adapter plate bearing pin 241 and guard shield 25.Derricking gear 3 is comprised of suspension rod 31, self-locking device 311, control desk 32, bearing plate 33, bearing plate bearing pin 331, chassis bearing pin 332 and chassis 34.Suspension rod 31 upper ends link through hole on supporting plate 22 and lifting lug device 1, and lower end links through hole on adapter plate 23 and chassis 34.Supporting plate 22 links by fixed link 23 and adapter plate 24.Adapter plate 24 is hinged by adapter plate bearing pin 241 and control desk 32.Control desk 32 is hinged by chassis bearing pin 332 and bearing plate 33.Bearing plate 33 is hinged by bearing plate bearing pin 331 and chassis 34.Adapter plate 24, control desk 32, bearing plate 33 and chassis 34 have formed double rocker mechanism jointly, and wherein control desk 32 and chassis 34 are rocking bar, and bearing plate 33 is connecting rod.During off working state, bearing plate 33 is in guard shield 25.During work, handle hanger handle 12 and support handle 21, make suspension rod 31 and support 2 produce relative motion, drive chassis 34 rotations, whole double rocker mechanism is moved.Meanwhile, bearing plate 33 is rotated centered by bearing plate bearing pin 331, and stretches out gradually.During lifting, self-locking device 311 compresses with supporting plate 22, and suspension rod 31 cannot produce relative motion with support 2, prevents that bearing plate 33 from producing motion under external force.
Two sides of described bearing plate 33 are arc, and its radius of curvature is identical with the radius of curvature on chassis 34, and under bearing plate 33 collapsed state, its outer rim is identical with chassis 34 outer rims.
The specific embodiment described in the utility model does not form the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
