Description

Technical Field

[0001] This utility model relates to the field of stage equipment technology, and in particular to a lifting and rotating stage with an anti-tilt safety locking mechanism. Background Technology

[0002] In the development of the modern performing arts industry, stage equipment has been constantly evolving to meet the increasingly diverse and demanding performance requirements. Early stages were mostly fixed structures with simple forms, making it difficult to realize complex scene changes and performance creativity. With the advancement of technology, stage equipment has gradually developed towards multi-functionality and automation.

[0003] In traditional rotating stages, the lack of effective anti-tilt devices makes them prone to tilting when the load is unevenly distributed, such as when actors are concentrated on one side of the stage or large props are placed unbalancedly. This not only affects the performance but also poses a serious threat to the safety of personnel and equipment on stage, potentially leading to actors falling and getting injured, props slipping and getting damaged. In addition, for some lifting stages, the stability of the lifting process is difficult to guarantee in some traditional designs with simple mechanical transmissions. They may not be able to withstand large load changes and may shake during the lifting process, affecting the normal use of the stage. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a lifting and rotating stage with an anti-tilt safety locking mechanism.

[0005] This utility model is achieved using the following technical solution: a lifting and rotating stage with an anti-tilt safety locking mechanism, comprising a mounting base plate, a protective shell fixedly connected to the upper surface of the mounting base plate, a motor fixedly connected to the inner wall of the protective shell, a worm gear fixedly connected to the output end of the motor, a worm wheel meshing with the surface of the worm gear, a lead screw fixedly connected inside the worm wheel, a lifting frame threadedly connected to the outer surface of the lead screw, side frames fixedly connected to both sides of the upper surface of the mounting base plate, a limit groove formed on the surface of the side frames, several lifting rods fixedly connected to the upper surface of the lifting frame, a rotating platform fixedly connected to the top of the lifting rods, an annular groove formed on the surface of the rotating platform, a second motor installed inside the rotating platform, a stage plate fixedly connected to the output end of the second motor, a guide rod fixedly connected to the lower surface of the stage plate, an anti-tilt support rod fixedly connected to the surface of the guide rod, and a limit groove formed on the inner wall of the annular groove.

[0006] The above technical solution realizes the lifting and rotating functions of the stage board, meeting the needs of different scenarios in stage performances. The self-locking function of the worm gear and worm wheel can effectively improve stability when lifting the stage board. The cooperation of the anti-tilt support rod and the limiting groove can effectively prevent the stage board from tilting during rotation, ensuring the safety of people or objects above the stage board.

[0007] As a further improvement to the above solution, the lifting frame is slidably connected to the inside of the limiting groove.

[0008] The above technical solutions ensure the directionality and stability of the lifting frame's movement, making the entire lifting process smoother and more reliable. This, in turn, ensures the stability of the stage panel's lifting and lowering, which is beneficial for protecting the safety of people and objects on the stage.

[0009] As a further improvement to the above solution, the guide rod is adapted to the annular groove, and the guide rod is rotatably connected inside the annular groove.

[0010] As a further improvement to the above solution, the anti-tilt support rod is adapted to the limiting groove, and the anti-tilt support rod is rotatably connected inside the limiting groove.

[0011] The above technical solutions directly prevent the stage panels from tilting during rotation, further improving the safety of stage performances and protecting personnel and equipment on stage from potential dangers caused by tilting.

[0012] As a further improvement to the above solution, diagonal braces are fixedly connected to both sides of the outer surface of the side frame, and the diagonal braces are fixedly connected to the upper surface of the mounting base plate.

[0013] The above technical solutions enhance the stability of the side frame, thereby improving the stability of the entire lifting and rotating stage structure and helping to keep the entire device stable during the lifting and rotation of the stage panels.

[0014] As a further improvement to the above solution, the surface of the worm gear is rotatably connected to a bearing seat, and the bearing seat is fixedly connected to the upper surface of the mounting base plate.

[0015] As a further improvement to the above solution, a limiting horizontal plate is fixedly connected to the surface of the side frame, the top end of the lead screw is rotatably connected to the lower surface of the limiting horizontal plate, and preset mounting holes are provided at the four corners of the upper surface of the mounting base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a motor to drive a worm gear, which in turn rotates through the meshing of the worm and worm wheel, thereby driving a lead screw. The rotation of the lead screw causes the lifting frame to move up and down along the limiting groove on the side frame surface. The lifting rod, rotating platform, and stage panel connected to the lifting frame can be raised. During the lifting process, the self-locking function of the worm and worm wheel enhances the safety of the stage during use. Simultaneously, when the stage panel rotates, the guide rod on the lower surface of the stage panel rotates along the annular groove on the rotating platform surface, and the anti-tilting support rod on the guide rod surface rotates along the limiting groove on the inner wall of the annular groove, effectively preventing the stage panel from tilting during rotation and ensuring the safety of personnel and props on stage.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5This embodiment of a lifting and rotating stage with an anti-tilt safety locking mechanism includes a mounting base plate 1. A protective shell 2 is fixedly connected to the upper surface of the mounting base plate 1. A motor 3 is fixedly connected to the inner wall of the protective shell 2. A worm gear 4 is fixedly connected to the output end of the motor 3. A worm wheel 5 is meshed with the surface of the worm gear 4. A lead screw 6 is fixedly connected inside the worm wheel 5. A lifting frame 7 is threadedly connected to the outer surface of the lead screw 6. Side frames 8 are fixedly connected to both sides of the upper surface of the mounting base plate 1. Limiting grooves are formed on the surface of the side frames 8. 9. Several lifting rods 10 are fixedly connected to the upper surface of the lifting frame 7. A rotating platform 11 is fixedly connected to the top of the lifting rods 10. An annular groove 12 is formed on the surface of the rotating platform 11. A second motor 13 is installed inside the rotating platform 11. A stage board 14 is fixedly connected to the output end of the second motor 13. A guide rod 15 is fixedly connected to the lower surface of the stage board 14. An anti-tilting support rod 16 is fixedly connected to the surface of the guide rod 15. A limit groove 17 is formed on the inner wall of the annular groove 12. When the first motor 3 is started, its output end drives the worm gear 4 to rotate. Since the worm gear 4 is meshed with the worm wheel 5, the rotation of the worm gear 4 will drive the worm wheel 5 to rotate. A lead screw 6 is fixedly connected inside the worm wheel 5, so the lead screw 6 rotates together with the worm wheel 5. The lifting frame 7 is threadedly connected to the outer surface of the lead screw 6. When the lead screw 6 rotates, the lifting frame 7 will rise and fall along the limit groove 9 on the surface of the side frame 8. Because several lifting rods 10 are fixedly connected to the upper surface of the lifting frame 7, when the lifting frame 7 rises, the lifting rods 10 lift the rotating platform 11, thereby raising the stage board 14 above. The self-locking function of the worm gear 4 and worm wheel 5 improves stability. After the motor 13 installed inside the rotating platform 11 is started, its output end drives the stage board 14 to rotate. The guide rod 15 on the lower surface of the stage board 14 rotates along the annular groove 12 on the surface of the rotating platform 11. The anti-tilting support rod 16 on the surface of the guide rod 15 rotates along the limiting groove 17 on the inner wall of the annular groove 12. This can effectively prevent the stage board 14 from tilting during rotation.

[0028] The lifting frame 7 is slidably connected to the inside of the limiting slide groove 9. This connection ensures that the lifting frame 7 can stably move up and down along the limiting slide groove 9 when the lead screw 6 rotates. When the lead screw 6 rotates, the lifting frame 7 will not deviate and can only move vertically in the direction specified by the limiting slide groove 9.

[0029] The guide rod 15 is adapted to the annular groove 12. The guide rod 15 is rotatably connected to the inside of the annular groove 12. When the stage board 14 is driven by the motor 13, the guide rod 15 rotates with the annular groove 12 as the track. This structure restricts the rotation path of the stage board 14, making it rotate according to the predetermined trajectory.

[0030] The anti-tilt support rod 16 is adapted to the limiting groove 17. The anti-tilt support rod 16 is rotatably connected to the inside of the limiting groove 17. During the rotation of the stage board 14, the anti-tilt support rod 16 rotates along the limiting groove 17. Due to the limiting effect of the limiting groove 17 on the anti-tilt support rod 16, the stage board 14 is prevented from tilting during rotation.

[0031] Both sides of the outer surface of the side frame 8 are fixedly connected to diagonal braces 18. The diagonal braces 18 are fixedly connected to the upper surface of the mounting base plate 1. The diagonal braces 18 serve to support the side frame 8 and share the pressure borne by the side frame 8 from components such as the lifting frame 7, the turntable 11, and the stage plate 14.

[0032] The worm gear 4 is rotatably connected to a bearing seat 19, which is fixedly connected to the upper surface of the mounting base plate 1.

[0033] The side frame 8 is fixedly connected to a limiting plate 20, and the top of the screw 6 is rotatably connected to the lower surface of the limiting plate 20. Pre-set mounting holes 21 are provided at the four corners of the upper surface of the mounting base plate 1.

[0034] The implementation principle of a lifting and rotating stage with an anti-tilt safety locking mechanism in this embodiment is as follows: The operator turns on the motor 3 inside the protective shell 2. The output end of the motor 3 drives the worm gear 4 to rotate. Since the worm gear 4 meshes with the worm wheel 5, the rotation of the worm gear 4 drives the worm wheel 5 to rotate. The lead screw 6 is fixedly connected inside the worm wheel 5. The lead screw 6 rotates accordingly. When the lead screw 6 rotates, the lifting frame 7, which is threaded to its outer surface, will move up and down along the limiting groove 9 on the surface of the side frame 8. Because the lifting frame 7 is slidably connected inside the limiting groove 9, the lifting frame 7 can only move up and down stably in the vertical direction without deviation. Several lifting rods 10 fixedly connected to the upper surface of the lifting frame 7 rise with the rise of the lifting frame 7. The rotating platform 11 fixedly connected to the top of the lifting rod 10 is also lifted accordingly, thereby driving the stage above. As stage panel 14 is raised, the self-locking function of worm gear 4 and worm wheel 5 improves the stability of the entire lifting process. When stage panel 14 is raised to the required height, the operator turns off motor 13 and stops the lifting operation. After stage panel 14 reaches the appropriate height, the operator starts motor 2 13 inside the turntable 11. The output end of motor 2 13 drives stage panel 14 to rotate. The guide rod 15 on the lower surface of stage panel 14 rotates along the annular groove 12 on the surface of the turntable 11. The anti-tilt support rod 16 on the surface of guide rod 15 rotates along the limiting groove 17 on the inner wall of the annular groove 12. Due to the limiting effect of the limiting groove 17 on the anti-tilt support rod 16, the stage panel 14 is effectively prevented from tilting during rotation. When stage panel 14 is rotated to the required angle, the operator turns off motor 2 13 and stops the rotation operation.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
