Embodiment

Consult Fig. 1, Fig. 2, the present invention includes bearing rotating ring 1, bearing fixed ring 2, radially two rollers 3 and axial roller 4, described 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, described bearing fixed ring 2 is the ring-shaped steel structure casing of segmentation, the cross section of casing is L-shaped, be arranged with the horizontal plane of annular and the outer facade of column on the bearing fixed ring 2, be laid with several axial roller base 21 along horizontal plane, be provided with the radially raceway 22 of annular along outer facade;

Consult Fig. 3, Fig. 4, described radially two roller 3 is by radially wheel seat 31 and two-wheel roller 32 form, two-wheel roller 32 vertically is articulated in radially on the wheel seat 31, and described axial roller 4 is comprised 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, described radially two roller 3 is several, be connected successively with several radially two roller base 11 of bearing rotating ring 1 through wheel seat 31 radially, axially roller 4 is several, be connected successively with several axial roller base 21 of bearing fixed ring 2 through axial wheel seat 41, bearing fixed ring 2 is fixed on the concrete foundation, bearing rotating ring 1 is positioned at bearing fixed ring 2 tops, and axially raceway 12 is supported on the wheel roller 42 of axial roller 4, and radially two rollers 3 touch on the radially raceway 22 of bearing fixed ring 2 through two-wheel roller 32.

Embodiment:

Consult Fig. 1, Fig. 3, Fig. 5, installation of the present invention: with bearing fixed ring 2 segmental hoistings on the column table top of constructure body structure 5, the splicing after levelling and with column table top embedded part firm welding, along outer facade raceway 22 is installed radially and adjust after fastening, the axial wheel seat 41 of several axial rollers 4 is installed on the axial roller base 21 of bearing fixed ring 2 successively, successively by the axial roller 4 of platform adjustment and fastening; With bearing rotating ring 1 segmental hoisting in bearing fixed ring 2 tops, and place on the axial roller 4, after the splicing and adjust the horizontal plane of axial raceway 12, the radially wheel seat 31 of several radially two rollers 3 is installed on radially two roller base 11 of bearing rotating ring 1 successively, successively by the radial clearance between the radially raceway 22 of the two-wheel roller 32 on the radially two rollers 3 of platform adjustment and bearing fixed ring 2, connecting drive device on axial roller 4 installs at last.
