Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting stage technology, specifically to a double-layer lifting stage. Background Technology
[0002] In the current field of stage performance arts, lifting stages play an indispensable role as crucial equipment for enhancing performance effects and improving the audience's visual experience. However, most lifting stages widely used in the market are limited to a single-layer lifting design. While this design can meet basic performance needs, it falls short in creating diverse and three-dimensional performance scenes, resulting in relatively monotonous performance effects that fail to fully showcase the charm and depth of stage art, thus affecting the audience's viewing experience and emotional resonance. Furthermore, existing single-layer lifting stages often lack effective measures to prevent obstruction of the stage boundaries after rising to the predetermined height.
[0003] This deficiency is particularly prominent in high-speed, highly dynamic stage performances. When actors perform vigorous actions such as jumping and running, if they inadvertently approach the edge of the stage, they may lose their balance and fall, endangering not only their personal safety but also potentially causing serious stage accidents and incalculable damage to the performance. This safety hazard is even more pronounced in large-scale outdoor performances or occasions requiring work at heights, posing a severe challenge to the safety and reliability of stage performances.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a double-layer lifting stage to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A double-layer lifting stage includes a support base, with positioning columns fixedly connected to both sides of the support base surface. A lifting cylinder is slidably sleeved on the outer surface of the positioning columns, and a stage base plate is fixedly connected to the top of the lifting cylinder. A retractable cylinder is fixedly connected to both sides of the support base surface, and a lifting screw is slidably installed inside the retractable cylinder. A transmission rod is fixedly connected to one side of the lifting cylinder and is fixedly connected to the lifting screw. A transmission worm gear is rotatably connected to the top of the retractable cylinder, and the inner wall of the transmission worm gear is threadedly connected to the lifting screw. A support plate is fixedly connected to the surface of the retractable cylinder on one side of the support base, and a transmission motor is fixedly installed on the surface of the support plate. An adjusting rod is fixedly connected to the transmission shaft of the transmission motor, and transmission worms are fixedly connected to both sides of the adjusting rod. The transmission worms are meshed with the transmission worm gear. A lifting protection mechanism is provided on the surface of the support base.
[0008] Furthermore, in order to achieve edge protection after the stage bottom edge is raised and lowered, the raising and lowering protection mechanism includes an adjustment groove on the edge of the stage bottom plate surface, a protective rod is rotatably connected inside the adjustment groove, a steel wire rope is fixedly connected to the end of the protective rod, and the end of the steel wire rope is fixedly connected to the support base.
[0009] Furthermore, in order to provide drop protection for the edge of the support base, the surface of the adjusting rod is threaded with transmission threads, and extrusion plates are threaded to both sides of the adjusting rod surface. A rubber airbag is fixedly connected to one side of the extrusion plate, and a ventilation pipe is fixedly installed on one side of the rubber airbag. A protective airbag is fixedly connected to the end of the ventilation pipe.
[0010] Furthermore, in order to limit the rotation of the extrusion plate, a positioning frame is fixedly connected to one side of the shrink cylinder, and a limit rod is fixedly connected to the surface of the positioning frame. The extrusion plate is slidably connected to the limit rod.
[0011] Furthermore, in order to achieve double-layer lifting on the stage base, a support column is fixedly connected to the bottom surface of the stage base, a bearing plate is fixedly connected to the end of the support column, electric push rods are fixedly installed on both sides of the surface of the bearing plate, and a lifting plate is fixedly installed at the end of the electric push rods. The lifting plate is slidably connected to the stage base.
[0012] Furthermore, in order to control the gas connection between the telescopic airbag and the protective airbag, an air intake valve is fixedly installed on one side of the surface of the ventilation duct.
[0013] Furthermore, in order to control the electrical components within the stage as a whole, a multi-control switch is fixedly installed on one side of the stage base.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The drive motor drives the adjusting rod to rotate, which in turn drives the worm gear on the adjusting rod to rotate the worm wheel. This causes the lifting screw to drive the lifting cylinder and stage base plate to move stably up and down through the drive rod. Furthermore, the electric push rod installed at the bottom of the stage base plate allows the lifting plate on the stage to be raised and lowered a second time, achieving double-layer lifting and adjustment of the stage. This provides a more complex and richer stage layout, allowing the audience to experience a more three-dimensional and vivid visual effect.
[0016] 2. After the stage base is raised and lowered, the tension of the steel wire rope in the lifting and protective mechanism pulls the protective rod in the adjustment groove, causing it to rotate and stand vertically with the stage base. This provides edge protection for the stage base, allowing stage personnel to hold onto the protective rod stably in case of a potential fall, preventing further descent. Simultaneously, as the stage base rises, the rotation of the adjustment rod brings the two compression plates on its surface closer together, squeezing and clamping the rubber airbag. This compresses the airbag into the protective airbag, providing effective fall protection to the surface of the supporting base. This dual protection provides a solid safety guarantee for stage personnel. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] According to an embodiment of the present invention, a double-layer lifting stage is provided.
[0027] Example 1:
[0028] like Figures 1-5As shown, a double-layer lifting stage according to an embodiment of the present invention includes a support base 1. Two pairs of positioning columns 2 are fixedly connected to both sides of the surface of the support base 1. A lifting cylinder 3 is slidably sleeved on the outer surface of each positioning column 2. A stage base plate 4 is fixedly connected to the top of the lifting cylinder 3. A pair of retractable cylinders 5 are fixedly connected to both sides of the surface of the support base 1. A lifting screw 6 is slidably installed inside the retractable cylinder 5. A transmission rod 7 is fixedly connected to an adjacent side of each pair of lifting cylinders 3. The transmission rod 7 is fixedly connected to the lifting screw 6. A transmission worm gear 8 is rotatably connected to the top of the retractable cylinder 5. The inner wall of the transmission worm gear 8 is threadedly connected to the lifting screw 6. The lifting screw 6 penetrates and extends into the interior of the retractable cylinder 5. A support plate 9 is fixedly connected to the surface of the retractable cylinder 5 on one side of the support base 1. A drive motor 10 is fixedly installed on the surface of the support plate 9. An adjusting rod 11 is fixedly connected to the drive shaft of the drive motor 10. A pair of drive worm gears 12 are fixedly connected to both sides of the adjusting rod 11. The drive worm gears 12 are meshed with the drive worm wheel 8. The drive motor 10 drives the adjusting rod 11 and the drive worm gears 12 to rotate, which in turn drives the drive worm wheel 8 to rotate. The inner wall of the drive worm wheel 8 is threadedly connected to the lifting screw 6, which drives the top drive rod 7 to move up and down. In turn, the drive rod 7 drives the lifting cylinder 3 and the stage base plate 4 to move up and down, thus achieving stable lifting and lowering of the stage base plate 4. The surface of the support base 1 is provided with a lifting protection mechanism 13, which is used to protect the stage base plate 4 and the edge of the support base 1 from falling after being raised.
[0029] like Figures 1-5As shown, the lifting and protective mechanism 13 includes multiple adjustment slots 1301 on the edge of the stage base 4. Each adjustment slot 1301 has a protective rod 1302 rotatably connected inside. A steel wire rope 1303 is fixedly connected to the end of the protective rod 1302. The end of the steel wire rope 1303 is fixedly connected to the support base 1, and the length of the steel wire rope 1303 is the same as the distance between the end of the protective rod 1302 and the support base 1 after the stage base 4 is raised. As the stage base 4 is raised, the steel wire rope 1303 gradually tightens. The tightened steel wire rope 1303 pulls the protective rod 1302 to move and rotate, thereby causing the protective rod 1302 to rotate to... Perpendicular to the surface of the stage base 4, it provides protection and obstruction to the edges of the stage base 4 after it is raised. The surface of the adjusting rod 11 has a transmission thread 1304, and a pair of compression plates 1305 are threaded to both sides of the adjusting rod 11. A rubber airbag 1306 is fixedly connected to one side of each compression plate 1305. This rubber airbag 1306 is inherently elastic and can automatically return to its initial state when not under pressure. A ventilation pipe 1307 is fixedly installed on one side of the rubber airbag 1306, and a protective airbag 1308 is fixedly connected to the end of the ventilation pipe 1307. The protective airbag 1308 is laid flat around the outer edge of the support base 1. A positioning frame 14 is fixedly connected to one side of the retractable cylinder 5. A limit rod 15 is fixedly connected to the surface of the positioning frame 14. The extrusion plate 1305 is slidably connected to the limit rod 15. When the stage base 4 is raised or lowered, the rotation of the adjusting rod 11 causes the extrusion plates 1305 on both sides of the adjusting rod 11 to move closer to each other and extrude the rubber airbag 1306. The gas in the rubber airbag 1306 enters the protective airbag 1308 through the ventilation pipe 1307, causing the protective airbag 1308 to inflate at the edge of the support base 1, thus achieving drop cushioning protection on the stage base 4. Two pairs of support columns 16 are fixedly connected to the bottom surface of the stage base 4. The ends of the support columns 16 are fixedly connected to the bottom surface of the stage base 4. A support plate 17 is fixedly connected, and a pair of electric push rods 18 are fixedly installed on both sides of the surface of the support plate 17. A lifting plate 19 is fixedly installed at the end of the electric push rod 18. The lifting plate 19 is slidably connected to the stage base plate 4. By extending and retracting the electric push rods 18, the lifting plate 19 on the surface of the stage base plate 4 can be raised and lowered, realizing the double-layer lifting on the stage base plate 4. An air inlet valve 20 is fixedly installed on one side of the surface of the ventilation pipe 1307 to control the gas connection between the rubber airbag 1306 and the protective airbag 1308. A multi-control switch 21 is fixedly installed on one side of the surface of the stage base plate 4 to control the various electrical components on the stage.
[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0031] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the transmission motor 10 drives the adjusting rod 11 and the transmission worm gear 12 to rotate, which in turn drives the transmission worm wheel 8 to rotate. The inner wall of the transmission worm wheel 8 is threadedly connected to the lifting screw 6, causing the lifting screw 6 to drive the top transmission rod 7 to move up and down. This, in turn, causes the transmission rod 7 to drive the lifting cylinder 3 and the stage base 4 to move up and down, achieving stable lifting and lowering of the stage base 4. As the stage base 4 rises, the steel wire rope 1303 gradually tightens, and the tightened steel wire rope 1303 pulls... The protective rod 1302 moves and rotates, thereby rotating the protective rod 1302 to be perpendicular to the surface of the stage base plate 4, so as to block and protect the edge of the stage base plate 4 after it is raised. Furthermore, by rotating the adjusting rod 11 when the stage base plate 4 is raised and lowered, the extrusion plates 1305 on both sides of the surface of the adjusting rod 11 move closer to each other and extrude the rubber airbag 1306. The gas in the rubber airbag 1306 enters the protective airbag 1308 through the ventilation pipe 1307, so that the protective airbag 1308 inflates at the edge of the support base 1, thereby achieving drop cushioning protection on the stage base plate 4.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
