The device can be used to mount lifting equipment, measuring tools, and temporary support structures on a rotating mechanism, or to combine one or two components together, to achieve seamless integration of multiple tasks and improve work efficiency.

[0043] A device for rotating around the central axis of cylindrical equipment comprises four parts: a central column device, a lower rotating sleeve, an upper rotating sleeve, and a rotating drive device. The central column device comprises a steel pipe column, a fixed support ring, a steel column base plate, and anchor bolts; the lower rotating sleeve comprises a first upper octagonal ring, a first lower octagonal ring, a first vertical roller, a horizontal wheel seat, a first wheel axle, a horizontal load-bearing wheel, and upper and lower rotating sleeve connecting steel plates; the upper rotating sleeve comprises a second upper octagonal ring, a second lower octagonal ring, a second vertical roller, a first tie steel pipe connecting plate, and a second tie steel pipe connecting plate; the rotating drive device comprises a drive device base, a motor, a rotating shaft, a rotating shaft seat, a rotating drive disc, and a circumferential guide wheel.

[0044] The middle column device is vertically fixed in the center of the circular structure equipment. The first upper octagonal ring and the first lower octagonal ring of the lower rotating sleeve are provided with corresponding circular holes on the upper and lower sides. There are protruding small shafts at both ends of the first vertical roller, which respectively penetrate into the circular holes of the first upper octagonal ring and the first lower octagonal ring. The first vertical roller is clamped between the first upper octagonal ring and the first lower octagonal ring. Four are arranged along the circumference of the steel pipe column. The rolling surface of the first vertical roller fits the surface of the steel pipe column and makes circular motion along the center of the steel pipe column. The horizontal wheel seat is fixed to the bottom of the first lower octagonal ring by bolts, and is connected with horizontal load-bearing wheels through the first wheel axle. Four are arranged along the circumference of the steel pipe column. The horizontal load-bearing wheels are in contact with the upper surface of the fixed support ring. The steel pipe column is welded to the fixed support ring to support the horizontal load-bearing wheels and make circular motion along the center of the steel pipe column.

[0045] There are several corresponding circular holes on the upper and lower sides of the second upper octagonal ring and the second lower octagonal ring of the upper rotating sleeve. There are protruding small shafts at both ends of the second vertical roller, which respectively penetrate into the circular holes of the second upper octagonal ring and the second lower octagonal ring. The second vertical roller is clamped between the second upper octagonal ring and the second lower octagonal ring. Four are arranged along the circumference of the steel pipe column. The rolling surface of the second vertical roller fits into the surface of the steel pipe column and makes circular motion along the center of the steel pipe column. The second upper octagonal ring and the second lower octagonal ring are welded together in the symmetrical direction through the first tie steel pipe connecting plate and the second tie steel pipe connecting plate.

[0046] The lower rotating sleeve and the upper rotating sleeve are welded into a whole through the upper and lower rotating sleeve connecting steel plates.

[0047] Four rotary drive units are arranged along the circumference of the steel column. Their drive unit bases are welded to the upper surface of the second upper octagonal ring. The upper surface of the drive unit base is divided into two sections: a high section housing the motor and a high section housing two rotating shaft mounts. Both the motor and the rotating shaft mounts are bolted to the drive unit base. The motor's driving end is connected to a rotating shaft, and the other end of the shaft is connected to a rotating drive disc. The rotating drive disc has a groove that aligns with the end face of the steel column, compressing it. When the motor is activated, the rotating drive disc rotates, causing the hoisting and measuring center column device to rotate along the steel column. Symmetrical trunnions extend from either side of the drive unit base, with their centers extending into the interior of the steel column. Circumferential guide wheels extend through the trunnions, contacting the inner wall of the steel column and pressing against it to prevent tipping. These guide wheels perform a circular motion along the steel column.
