The diagnostic instruments above the equator of the spherical device are widely distributed, and the inclination angles with the vertical direction are discrete and diverse. Most diagnostic instruments are installed on the spherical device by hoisting. During the installation process, multiple hoisting points and towing points need to be set up to dock the installation interface of the diagnostic instrument. The operation is cumbersome and the accuracy is low.

The other components and connection methods are the same as those in the sixth embodiment.

[0049] In combination with the description of specific embodiments five to seven, the rotation drive mechanism 7 provides power for the circular clamp 2 to rotate around its own axis, wherein the driving gear 73 is meshed with the teeth of the toothed upper half ring 21 to realize power transmission, and an arc-shaped through groove is processed on the outer wall of the mounting frame 1 for cooperating with the external pressure cover 15 to form a rotating shaft mounting hole 14 for accommodating the driving gear 73, and the external pressure cover 15 and the mounting frame 1 are disassembled and connected by bolts, and the two ends of the driving gear 73 are rotatably connected to the mounting frame 1 and the shell part of the external pressure cover 15 through bearings, and bearing end covers are also provided at both ends of the rotating shaft mounting hole 14 for fixing the bearings, and one of the two driving gears 73 acts as a coupling, which is synchronously mounted on the power output shaft of the rotating motor 71 and one end of the rotating shaft 72, and is fastened to the two by a key, and by installing a long guide flat key on the rotating shaft 72, the center distance of the two clamp assemblies can be adjusted, and the adaptability to the hoisting position of the hoisted object is better.

The driving reduction motor 41 drives the transmission screw 42 to rotate and causes the transmission nut 43 to reciprocate along the axial direction of the transmission screw 42. Driven by the transmission nut 43, the hanging point 5 reciprocates along the length extension direction of the two sliding rods 6. Other components and connection methods are the same as those in the eighth embodiment.

[0053] In this embodiment, the sliding drive mechanism 4 can make the hoisted workpiece move in translation relative to the hoisting point, thereby adjusting the tilt angle of the hoisted workpiece by changing the relative position of the hoisting point and the center of gravity. The drive motor 41 can be replaced by a hydraulic motor, a pneumatic motor, etc. according to actual working conditions, and the transmission screw 42 can be a T-screw or a ball screw;

[0054] The center distance between the two clamp components is adjustable, and manual adjustment of the center distance is more adaptable to the hoisting position of the hoisted object. There is a long guide flat key on the shaft of the rotating drive mechanism, and the clamp component, transmission gear, and mounting frame can be translated along the flat key as a whole. After translation, the mounting frame and the slide rod are locked in the sliding position through the top screw on the top of the mounting frame.
