Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail:
A kind of many legs of radius adjustable rigid that support support centering structure, comprise supporting leg fixed mount 3, be fixed on supporting leg fixed mount 3 outer circumferential and the scalable adjustment rigid leg 1 of two length of circumferential even angular intervals and a cylinder supporting leg 2;
The scalable adjustment rigid leg 1 of length comprises supporting leg pipe 8, turbine and worm assembly;
Turbine and worm assembly comprises air motor 6, worm gear case 7; Worm gear case 7 is fixed on the outer end of supporting leg pipe 8; Air motor 6 is arranged on outside worm gear case 7; Also comprise screw mandrel 5, worm gear 11, worm screw 12; Worm gear 11, worm screw 12 are placed in worm gear case 7 by bearings;
Leading screw 5 and worm gear 11 are threaded connection, and form screw-nut structure, penetrate in supporting leg pipe 8 outside supporting leg pipe 8;
Worm gear 11 coordinates with worm screw 12 turbine and worm; Worm screw 12 is connected with air motor 6 output shaft;
Leading screw 5 is flat column shape structure, and leading screw 5 is through leading screw guide 10, and the hole of leading screw guide 10 is consistent with the periphery of leading screw 5, and is slidably matched with leading screw 5, thus limits the circumference rotation of 5, can only axially-movable; It is inner and fixing that leading screw guide 10 is arranged on supporting leg pipe 8 outer end;
The end that supporting leg cushion block 4 is positioned at outside supporting leg pipe 8 with leading screw 5 is connected;
