Embodiment

Consult Fig. 1, Fig. 2, the present invention includes that bearing rotating ring 1, bearing encircle 2 surely, radially two roller 3 and axial roller 4, said bearing rotating ring 1 is the ring-shaped steel structure casing of segmentation; The lower plane of casing is divided into inner ring and outer ring along circumference; Be laid with several radially two roller base 11 along inner ring, be provided with the axial raceway 12 of annular along the outer ring, said bearing encircles 2 surely and is the ring-shaped steel structure casing of segmentation; The cross section of casing is L-shaped; Bearing encircles surely and is arranged with the annular horizontal plane and the outer facade of column on 2, is laid with several axial roller base 21 along horizontal plane, is provided with the radially raceway 22 of annular along outer facade;

Consult Fig. 3, Fig. 4; Said radially two roller 3 is by radially wheel seat 31 and two-wheel roller 32 are formed; Two-wheel roller 32 vertically is articulated in radially on the wheel seat 31, and said axial roller 4 is made up of axial wheel seat 41 and wheel roller 42, and wheel roller 42 is horizontally hinged on axial wheel seat 41;

Consult Fig. 2, Fig. 3, Fig. 4; Said radially two roller 3 is several; Is connected successively with several radially two roller base 11 of bearing rotating ring 1 through wheel seat 31 radially, axially roller 4 is several, and axial wheel seat 41 of warp and bearing encircle several axial roller base 21 of 2 surely and be connected successively; Bearing encircles 2 surely and is fixed on the concrete foundation; Bearing rotating ring 1 is positioned at bearing and encircles 2 tops surely, and axially raceway 12 is supported on the wheel roller 42 of axial roller 4, and radially two rollers 3 touch on bearing encircles 2 radially raceway 22 surely through two-wheel roller 32.

Embodiment:

Consult Fig. 1, Fig. 3, Fig. 5; Installation of the present invention: bearing is encircled 2 segmental hoistings surely on the column table top of constructure body structure 5; The levelling of splicing back and with column table top embedded part firm welding; Raceway 22 is installed radially and the adjustment back is fastening along outer facade, the axial wheel seat 41 of several axial rollers 4 is installed in bearing successively encircles surely on 2 the axial roller base 21, it is also fastening to adjust axial roller 4 by platform successively; Bearing rotating ring 1 segmental hoisting is encircled 2 tops surely in bearing; And place on the axial roller 4; The horizontal plane of axial raceway 12 is also adjusted in splicing back, with several radially the radially wheel seat 31 of two rollers 3 be installed in successively on radially two roller base 11 of bearing rotating ring 1, encircle the radial clearance between 2 the radially raceway 22 surely by the two-wheel roller 32 on the radially two rollers 3 of platform adjustment and bearing successively; Axially connecting drive unit on the roller 4, install at last.
