The stage foundation pit is mainly used for installing the stage rotating and lifting platform.

[0035] Specifically, the stage rotating and lifting platform of this embodiment includes a rotating structure 10, a main frame structure 20, and a standing platform structure 30;

[0036] The rotating structure 10 includes a rotating base 11, a column structure 12, and a rotation driving device 13; the rotating base 11 is fixed to the bottom of the stage foundation pit to play a supporting and load-bearing role. The column structure 12 is vertically arranged in the stage foundation pit. The bottom of the column structure 12 is rotationally connected to the rotating base 11 through a bearing assembly, so that the column structure 12 can rotate relative to the rotating base 11. The rotation axis of the column structure 12 is vertically arranged, and the rotation driving device 13 is used to drive the column structure 12 to rotate.

[0037] The main frame structure 20 includes a frame main body 21 and a lifting driving device 22. Both ends of the frame main body 21 form a first end 211 and a second end 212 respectively; the first end 211 of the frame main body 21 is hinged to the top of the column structure 12, so that the frame main body 21 can rotate relative to the column structure 12. The rotation axis of the first end 211 of the frame main body 21 is horizontally arranged. The second end 212 of the frame main body 21 is connected to the standing platform structure 30. The lifting driving device 22 is linked with the frame main body 21. By providing power through the lifting driving device 22, the frame main body 21 is driven to rotate relative to the column structure 12, thereby driving the standing platform structure 30 to lift.

[0038] The stage rotating and lifting platform of this embodiment installs the standing platform structure 30 at the end of the main skeleton body 21. The main skeleton body 21 is connected to the column structure 12. The column structure 12 is driven by the rotation driving device 13 to rotate around the vertical direction, thereby driving the standing platform structure 30 to rotate. The main skeleton body 21 is driven by the lifting driving device 22 to rotate around the horizontal direction relative to the column structure 12, thereby driving the standing platform structure 30 to lift. Thus, the rotation and lifting functions of the standing platform structure 30 are realized. In this embodiment, by adopting the method of linkage of double driving devices and using the main skeleton structure 20 as a rotating arm, the functions of rotating and lifting the standing platform structure 30 are respectively controlled by the rotation driving device 13 and the lifting driving device 22. On the premise of ensuring the safety load, the thickness of the main skeleton structure 20 is minimized, making its volume smaller, saving the equipment installation space, reducing the blocking of the audience's viewing line of sight, and enhancing the stage effect.

[0039] Furthermore, a skeleton platform 213 is formed on one side of the main skeleton body 21. The main skeleton body 21 has a first angle and a second angle. When the main skeleton body 21 is at the first angle, the skeleton platform 213 forms a flush plane with the stage ground, hiding the stage rotating and lifting platform in the stage foundation pit. When the main skeleton body 21 is at the second angle, the skeleton platform 213 forms an angle with the stage ground, driving the standing platform structure 30 to rise to the limit position, so as to quickly change the scenery and meet the requirements of different process layouts, stage art designs, etc.

Powered by the rotation driving device 13, through the cooperation of the second meshing tooth and the first meshing tooth, the rotation driving device 13 is driven to rotate around the gear ring, driving the column structure 12 to rotate. By the cooperation of the gear ring and the gear, the output torque of the rotation driving device 13 is amplified, providing a more stable rotation driving force for the column structure 12 and improving the positioning accuracy and stability of the standing platform structure 30 during the rotation process.

Through the main control system, the lifting drive device 22 and the balance drive device 32 are interlocked and linked. The start-up and shutdown sequences are strictly programmed and interlocked to ensure safety. During the rotation of the column structure 12 and the simultaneous rotation and lifting of the main frame structure 20, the balance drive device 32 keeps the platform main body 31 parallel to the stage ground at the same time.
