A kind of roller ball with stable platform
Technical field
The utility model relates to a kind of roller ball with stable platform.
Background technology
The development of pipe detection technical need, need to be arranged into sensor in tube fluid and go, by different sensors, and the information such as abnormal, the inner-walls of duct of test fluid, the variation of pipeline geography position.This just requires detecting sensor to need stable, a lasting measuring table.Traditional stable detection platform structure complexity, operation inconvenience, causes very large difficulty to O&M.
Utility model content
The technical matters that the utility model solves is: roll by spherical housing, interior ring, outer shroud coordinate adjustment with axle, realize the steady state (SS) over the ground of eccentric inner platform.
The technical scheme that the utility model is taked is: a kind of roller ball with stable platform, is characterized in that: the described roller ball with stable platform comprises sphere shell and internal stability mechanism; Sphere shell comprises two hemispherical Shells in left and right, is respectively spherical shell A1 and spherical shell B8; Internal stability structure comprises outer annulate shaft A3, outer annulate shaft B6, outer shroud 2, inner platform 4, inner axle A5, inner axle B7; In hemispherical Shell spherical shell A1 and spherical shell B8 for etc. radius spheroid, and two hemisphere are concentric; Outer shroud 2 is assemblied between spherical shell A1 and spherical shell B8 by outer annulate shaft A3, outer annulate shaft B6, and outer annulate shaft A3, outer annulate shaft B6 be on same straight line, and the centre of sphere of this straight-line pass spherical shell A1 and spherical shell B8; The axis that outer shroud 2 can form around outer annulate shaft A3 and outer annulate shaft B6 freely rotates; Inner platform 4 is connected with outer shroud 2 by two coupling shaft inner axle A5, inner axle B7, and the axis that the inner platform 4 of centre offset can form around inner axle A5, inner axle B7 freely rotates, and this axis is also by the centre of sphere of spherical shell A1 and spherical shell B8; The axes intersect that the axis that outer annulate shaft 2, outer annulate shaft B6 form and inner axle A5, inner axle B7 form is in the centre of sphere of spherical shell A1 and spherical shell B8, and two axial lines is orthogonal in formed plane.
The utlity model has beneficial effect: a kind of roller ball with stable platform of the utility model, in rolling process, keep the stable of inside panel in any direction, design ingenious, easy to operate.

Fig. 2 is internal stability mechanism structure schematic diagram in the roller ball of the band of the utility model shown in Fig. 1 stable platform;
Wherein, 1-spherical shell A, 2-outer shroud, the outer annulate shaft A of 3-, 4-inner platform, 5-inner axle A, 6-outer annulate shaft B, 7-inner axle B, 8-spherical shell B.
Embodiment
Below in conjunction with Figure of description, embodiment of the present utility model is described further.
Referring to Fig. 1, Fig. 2, the roller ball of the utility model band stable platform, comprises sphere shell and internal stability mechanism.Sphere shell comprises two hemispherical Shells in left and right, is respectively spherical shell A1 and spherical shell B8; Internal stability structure comprises outer annulate shaft A3, outer annulate shaft B6, outer shroud 2, inner platform 4, inner axle A5, inner axle B7.In hemispherical Shell spherical shell A1 and spherical shell B8 for etc. radius spheroid, and two hemisphere are concentric.Outer shroud 2 is assemblied between spherical shell A1 and spherical shell B8 by outer annulate shaft A3, outer annulate shaft B6, and outer annulate shaft A3, outer annulate shaft B6 be on same straight line, and the centre of sphere of this straight-line pass spherical shell A1 and spherical shell B8.The axis that outer shroud 2 can form around outer annulate shaft A3 and outer annulate shaft B6 freely rotates.Inner platform 4 is connected with outer shroud 2 by two coupling shaft inner axle A5, inner axle B7, and the axis that the inner platform 4 of centre offset can form around inner axle A5, inner axle B7 freely rotates, and this axis is also by the centre of sphere of spherical shell A1 and spherical shell B8.So the axes intersect that the axis that outer annulate shaft 2, outer annulate shaft B6 form and inner axle A5, inner axle B7 form is in the centre of sphere of spherical shell A1 and spherical shell B8, and two axial lines is orthogonal in formed plane.Wherein, when roller ball is during around Y-axis rolling movement, rotate around inner axle A5, inner axle B7 by the inner platform 4 of centre offset, adjust self attitude, remain that inner platform 4 is stable; When roller ball is during around X-axis rolling movement, by the inner platform 4 of centre offset and being connected of outer shroud 2, outer shroud 2 rotates around outer annulate shaft A3, outer annulate shaft B6, adjusts self attitude, remains that inner platform 4 is stable; When roller ball is during around Z axis rolling movement, rotate around inner axle A5, inner axle B7 by the inner platform 4 of centre offset, adjust self attitude, remain that inner platform 4 is stable.
