DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1-Figure 5As shown, the rotating column structure that can be switched manually or electrically in the mobile DR includes a rotating disk 5, which is rotatably mounted on a chassis 6, and a vertically arranged column is mounted on the rotating disk 5. In practice, the column is divided into a rotating column upper moving part 3 and a rotating column lower fixed part 4, wherein the column lower fixed part 4 is fixed on the rotating disk 5, and the column lower fixed part 4 can rotate along the vertical axis of the rotating disk 5. The column upper moving part 3 is connected to the end head assembly 1 through a telescopic arm 2, and a body 7 is also mounted on the chassis 6; it also includes a belt-away device. The chassis 6 is provided with a reduction motor 11 with a combined function, a support frame 12, and the reduction motor 11 is installed on the support frame 12. The reduction motor 11 can drive the rotating disk 5 to rotate through a transmission component. The chassis 6 also has an adjusting member for fine-tuning the position of the support frame 12. Specifically, the adjusting member is a screw 10; under the action of the screw 10, the adjusting member moves back and forth to adjust the distance between the support frame 12 and the rotating disk 5, and then adjusts the meshing distance between the driving gear three 15 and the gear ring. This adopts the existing technology to achieve its position fine-tuning.

[0023] The reduction motor 11 includes a planetary reduction motor and an electromagnetic brake, which are existing products.

[0024] Of course, this solution can also be adopted, where the reduction motor 11 is a clutch motor, that is, other motors with a clutch function can still achieve the same effect.

[0025] The transmission assembly includes a driving gear 1 13, a driving gear 2 14 and a driving gear 3 15. The driving gear 1 13 is installed on the end of the output shaft of the reduction motor 11. The driving gear 2 14 and the driving gear 3 15 are coaxially installed on the support frame 12. The driving gear 2 14 and the driving gear 3 15 rotate synchronously. The driving gear 2 14 is meshed with the driving gear 1 13, and the driving gear 3 15 is meshed with the ring gear of the rotating disk 5.

[0026] The rotating disk 5 includes a slewing support bearing 8, and the driving gear 3 15 is meshed with the gear ring of the slewing support bearing 8; the slewing support bearing 8 adopts the existing structure.

[0027] During operation, the reduction motor 11 drives the driving gear 1 13, the driving gear 1 13 drives the driving gear 2 14, the driving gear 2 14 drives the driving gear 3 15, and the driving gear 3 15 drives the supporting plate to rotate; the size relationship of the driving gear 1 13, the driving gear 2 14, and the driving gear 3 15 depends on the rotation speed requirement of the slewing support bearing 8; the transmission mode is gear transmission, and in practice, if it is changed to chain transmission or synchronous belt transmission, the same effect can still be achieved; similarly, the speed change of large and small gears is a single speed change, and if it is changed to multiple speed changes, the same effect can still be achieved.

[0028] When the reduction motor 11 adopts a planetary reduction motor and an electromagnetic brake structure, if the electromagnetic brake is released, the column can be rotated manually. When the electromagnetic brake loses power, it will clamp the motor rotating shaft of the planetary reduction motor to achieve a braking effect. When electric operation is required, the planetary reduction motor and the electromagnetic brake are energized at the same time, and the motor rotating shaft of the planetary reduction motor rotates normally, thereby driving the rotating disk 5 to rotate. When the power is off, the brake is locked to achieve a braking effect.

[0029] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
