Description

Technical Field

[0001] This utility model relates to the field of performing arts equipment, and in particular to a multi-ring rotating lifting platform for stage performance applications. Background Technology

[0002] Currently, in the field of performing arts equipment, multi-ring turntable technology, multi-ring / layer lifting platform technology, and rotating lifting platform technology are all very mature and widely used in practice. However, a technology for performing arts equipment required for multi-ring and independently rotating and rotating lifting scenarios has not yet been publicly reported. To meet the needs of multi-ring and independently rotating performance scenarios, this utility model designs and develops a ring-shaped rotating lifting platform. Utility Model Content

[0003] The purpose of this invention is to provide a ring-shaped rotating lifting platform to meet the performance needs in multi-ring rotating lifting application scenarios.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A circular rotating lifting platform includes a wooden platform surface, a circular rotating platform system, and a lifting system;

[0006] The rotary table system includes a rotary table steel structure, a rotary table support, a rotary table slewing support, and a rotary table drive motor. The rotary table slewing support is an internal gear ring slewing bearing. The top of the rotary table steel structure is fitted with a wooden tabletop decoration. The bottom of the rotary table steel structure is fixedly installed on the top of the inner ring of the rotary table support. The bottom of the outer ring of the rotary table support is bolted to the rotary table support. The rotary table drive motor is fixed to the inner side of the rotary table support. The first drive gear on the output shaft of the rotary table drive motor meshes with the internal gear ring of the rotary table support.

[0007] The lifting system includes a screw and nut lifting assembly, a lifting slewing support, a lifting drive motor, and a fixed support. The lifting slewing support is an external gear ring slewing support. Multiple screw and nut lifting assemblies are evenly arranged circumferentially on the outside of the lifting slewing support. The bottom of the inner ring of the lifting slewing support is fixed to the fixed support. The screw and nut lifting assemblies and the lifting drive motor are both mounted on the fixed support. The second drive gear on the output shaft of the lifting drive motor meshes with the external gear ring of the lifting slewing support. The bottom of the rotating platform support is threadedly connected to the screw and nut lifting assembly. The lifting drive motor drives the external gear ring of the lifting slewing support to rotate, thereby driving the screw and nut lifting assembly to rotate, and thus causing the rotating platform system threadedly connected to the screw and nut lifting assembly to perform lifting and lowering movements.

[0008] Furthermore, the lead screw lifting nut lifting assembly is provided with 6 sets.

[0009] Furthermore, the lead screw nut lifting assembly includes a lifting nut, a lead screw, a driven gear, a fixed lead screw support, and a movable lead screw support. The fixed lead screw support is fixedly installed on a fixed support, and the lower end of the lead screw is rotatably installed on the movable lead screw support through a thrust bearing. The movable lead screw support is bolted to the fixed lead screw support. The driven gear is located in the middle of the lead screw and meshes with the outer gear ring of the lifting and rotating support. The lifting nut is fixed on the ring turntable support and is threadedly connected to the lead screw.

[0010] Due to the adoption of the above technical solution, the beneficial technical effects of this utility model are as follows:

[0011] Compared to multiple independent lifting technologies, the circular rotary lifting platform of this utility model adopts a single rotary lifting technology, which better meets the synchronization requirements during equipment lifting and lowering, while greatly saving the space required for the arrangement of transmission components.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following describes this utility model in further detail through preferred embodiments.

[0018] Example

[0019] Please see the appendix Figure 1-4 As shown in the figure, the circular rotating lifting platform provided in this embodiment includes a wooden platform 1, a circular rotating platform system 2, and a lifting system 5 arranged from top to bottom.

[0020] Specifically, the rotary table system 2 includes a rotary table steel structure 6, a rotary table support 3, a rotary table slewing support 7, and a rotary table drive motor 8. The rotary table slewing support 7 is an internal gear ring slewing bearing. A wooden tabletop decoration 1 is installed on the top of the rotary table steel structure 6. The bottom of the rotary table steel structure 6 is fixedly installed on the top of the inner ring of the rotary table support 7. The bottom of the outer ring of the rotary table support 7 is bolted to the rotary table support 3. The rotary table drive motor 8 is fixed inside the rotary table support 3. A first drive gear 16 on the output shaft of the rotary table drive motor 8 meshes with the internal gear ring of the rotary table support 7. The rotary table drive motor 8 drives the internal gear ring of the rotary table support 7 to rotate through the first drive gear 16, thereby causing the rotary table steel structure 6, installed on the top of the inner ring of the rotary table support 7, to rotate.

[0021] Specifically, the lifting system 5 includes a lead screw 9 lifting nut 4 lifting assembly, a lifting rotary support 11, a lifting drive motor 12, and a fixed support 13. The lifting rotary support 11 is an external gear ring rotary support. Multiple lead screw 9 lifting nut 4 lifting assemblies are evenly arranged circumferentially on the outside of the lifting rotary support 11. The bottom of the inner ring of the lifting rotary support 11 is fixed to the fixed support 13. The lead screw 9 lifting nut 4 lifting assembly and the lifting drive motor 12 are both mounted on the fixed support 13. The second drive gear 17 on the output shaft of the lifting drive motor 12 meshes with the external gear ring of the lifting rotary support 11. The bottom of the ring turntable support 3 is threadedly connected to the lead screw 9 lifting nut 4 lifting assembly. The lifting drive motor 12 drives the external gear ring of the lifting rotary support 11 to rotate, thereby driving the lead screw 9 lifting nut 4 lifting assembly to rotate, and thus causing the ring turntable system 2 threadedly connected to the lead screw 9 lifting nut 4 lifting assembly to perform lifting motion.

[0022] Specifically, the lead screw 9 nut lifting assembly includes a lifting nut 4, a lead screw 9, a driven gear 10, a fixed lead screw support 14, and a movable lead screw support 15. The fixed lead screw support 14 is fixedly installed on the fixed support 13. The lower end of the lead screw 9 is rotatably installed on the movable lead screw support 15 through a thrust bearing. The movable lead screw support 15 is bolted to the fixed lead screw support 14. The driven gear 10 is located in the middle of the lead screw 9 and meshes with the outer gear ring of the lifting rotary support 11. The lifting nut 4 is fixed on the ring turntable support 3 and is threadedly connected to the lead screw 9. The lifting drive motor 12 drives the outer gear ring of the lifting rotary support 11 to rotate through the second drive gear 17, thereby causing the gear meshing with the outer gear ring of the lifting rotary support 11 to rotate. The lead screw 9 rotates accordingly, and the lifting nut 4 rises and falls with the rotation of the lead screw 9.

[0023] In this embodiment, the lifting assembly of the lead screw 9 and the lifting nut 4 is provided in 6 sets. In other embodiments, the number of lifting assemblies of the lead screw 9 and the lifting nut 4 is appropriately increased or decreased according to the diameter and load conditions of the rotary table system 2.
