Description

Technical Field

[0001] This utility model belongs to the field of stage lifting technology, and in particular relates to a stage lifting device. Background Technology

[0002] Currently, when actors enter or perform, they are usually slowly lifted off the stage using a lift platform to enhance their entrance. The lifting and lowering of this platform is typically achieved using a lifting mechanism.

[0003] However, existing lifting devices can only achieve basic lifting functions and lack effective protection measures for actors when they are raised to high positions. When actors are raised to high and dangerous positions, they are very likely to fall off the stage due to instability, resulting in serious injuries and posing significant safety hazards. Utility Model Content

[0004] To address the technical problem that existing stage lifting devices lack safety protection measures at heights, which can easily lead to serious injuries to performers who fall off the stage, this utility model provides a stage lifting device.

[0005] This utility model is implemented as follows: a stage lifting device includes: a stage body; an installation cavity formed on the stage body, the top inner wall of the installation cavity having an opening; an annular shell disposed in the installation cavity, the top of the annular shell having a support plate fixedly installed, a lifting platform for lifting actors being disposed above the support plate; and a protective mechanism assembled on the support plate for protecting actors.

[0006] Preferably, the protective mechanism includes: an electric telescopic rod fixedly installed at the bottom of the support plate, with a support block fixedly installed on the output rod of the electric telescopic rod; and a transparent protective cover slidably fitted on the lifting platform, with the inner wall of the transparent protective cover fixedly connected to the support block, and the transparent protective cover located inside the opening.

[0007] Preferably, the stage lifting device further includes a height adjustment mechanism installed in the mounting cavity for lifting the support plate.

[0008] Preferably, the height adjustment mechanism includes: a screw rotatably mounted on the inner wall of the bottom of the mounting cavity, a sleeve threaded onto the screw, the top end of the sleeve being fixedly connected to the support plate; a dual-axis motor fixedly mounted on the inner wall of the bottom of the mounting cavity, a first bevel gear fixedly sleeved on the output shaft of the dual-axis motor; and a second bevel gear fixedly sleeved on the screw, the second bevel gear meshing with the first bevel gear.

[0009] Preferably, the stage lifting device further includes a rotating mechanism mounted on the support plate for rotating the lifting platform. The rotating mechanism includes: a housing fixedly mounted on the support plate, a geared motor fixedly mounted on the inner wall of the housing, and the output shaft of the geared motor fixedly connected to the bottom of the lifting platform.

[0010] Preferably, the top of the support plate is provided with a groove, and a ball bearing is provided in the groove, the ball bearing being in contact with the bottom of the lifting platform.

[0011] Preferably, an arc-shaped foot buckle is fixedly installed on the top of the lifting platform, a limit rod is fixedly installed on the inner wall of the mounting cavity, a limit plate is slidably installed on the limit rod, and one side of the limit plate is fixedly connected to the annular shell.

[0012] Compared with related technologies, the stage lifting device provided by this utility model has the following beneficial effects:

[0013] This solution utilizes a protective mechanism that allows the transparent protective shield to be raised to a higher position when the lift platform raises the performer to a relatively dangerous height. The top of the transparent protective shield is higher than the lift platform, gradually forming a transparent protective barrier around the performer. This effectively prevents the performer from falling off the stage due to instability during the performance, greatly improving the safety of performers performing at heights. It effectively solves the technical problem of existing stage lifting devices lacking height safety protection measures, which makes it easy for performers to suffer serious injuries from falling off the stage.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a stage lifting device, such as... Figure 1-4 As shown, the stage lifting device includes: a stage body 1; a mounting cavity 2 opened on the stage body 1, the top inner wall of the mounting cavity 2 having an opening; an annular shell 3 disposed in the mounting cavity 2, a support plate 4 fixedly installed on the top of the annular shell 3, a lifting platform 5 for lifting actors being disposed above the support plate 4; and a protective mechanism for protecting actors mounted on the support plate 4.

[0022] In the solution, when using the lifting device to lift the actor standing on the lifting platform 5, a height adjustment mechanism can be used to lift the support plate 4 and the lifting platform 5, so that the lifting platform 5 can lift the actor to the corresponding height for performance. When the lifting platform 5 is at a relatively dangerous height, the protective mechanism can be activated to shield and protect the actor's surroundings to prevent the actor from falling off the stage due to instability, which can effectively reduce safety hazards.

[0023] In a further preferred embodiment of the present invention, the protective mechanism includes: an electric telescopic rod 6 fixedly installed at the bottom of the support plate 4, a support block 7 fixedly installed on the output rod of the electric telescopic rod 6; and a transparent protective cover 8 slidably sleeved on the lifting platform 5, the inner wall of the transparent protective cover 8 being fixedly connected to the support block 7, and the transparent protective cover 8 being located inside the opening.

[0024] In this embodiment, the protective mechanism is used to protect the performers. When in use, the electric telescopic rod 6 is activated to drive the support block 7 to rise. The support block 7 will drive the transparent protective cover 8 to rise, so that the top of the transparent protective cover 8 can be higher than the lifting platform 5. The transparent protective cover 8 can shield and protect the performers from falling off the stage due to instability during the performance, which can greatly improve the safety of performers performing at heights.

[0025] In a further preferred embodiment of the present invention, the stage lifting device further includes a height adjustment mechanism for lifting the support plate 4 installed in the mounting cavity 2.

[0026] In this embodiment, the height adjustment mechanism is used to raise and lower the support plate 4. When the support plate 4 is raised and lowered, the lifting platform 5 above the support plate 4 will also be raised and lowered at the same time.

[0027] In a further preferred embodiment of this utility model, the height adjustment mechanism includes: a screw 9 rotatably mounted on the inner wall of the bottom of the mounting cavity 2, a sleeve 10 threadedly mounted on the screw 9, the top end of the sleeve 10 being fixedly connected to the support plate 4; a dual-axis motor 11 fixedly mounted on the inner wall of the bottom of the mounting cavity 2, a first bevel gear 12 fixedly sleeved on the output shaft of the dual-axis motor 11; and a second bevel gear 13 fixedly sleeved on the screw 9, the second bevel gear 13 meshing with the first bevel gear 12.

[0028] In this embodiment, when the height adjustment mechanism is in use, the dual-axis motor 11 is started, which drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the screw 9 to rotate through the second bevel gear 13. The screw 9 drives the sleeve 10 to move vertically, and the sleeve 10 drives the support plate 4 and the lifting platform 5 to rise and fall, so that the lifting platform 5 can raise the actor to the corresponding height for performance.

[0029] In a further preferred embodiment of the present invention, the stage lifting device further includes a rotating mechanism installed on the support plate 4 for rotating the lifting platform 5. The rotating mechanism includes: a housing 14 fixedly installed on the support plate 4, a reduction motor 15 fixedly installed on the inner wall of the housing 14, and the output shaft of the reduction motor 15 fixedly connected to the bottom of the lifting platform 5.

[0030] In this embodiment, the lifting platform 5 can be rotated according to the needs of the performance by using the rotating mechanism. When in use, the reduction motor 15 is started, and the output shaft of the reduction motor 15 will drive the lifting platform 5 to rotate above the support plate 4, so that the actor standing on the lifting platform 5 will also rotate together to achieve the desired performance effect.

[0031] In a further preferred embodiment of the present invention, a groove is provided on the top of the support plate 4, and a ball bearing 16 is provided in the groove, the ball bearing 16 being in contact with the bottom of the lifting platform 5.

[0032] In this embodiment, the use of ball bearings 16 enables the lifting platform 5 to be used stably above the support plate 4, preventing significant shaking of the lifting platform 5 during use.

[0033] In a further preferred embodiment of this utility model, an arc-shaped foot buckle 17 is fixedly installed on the top of the lifting platform 5, a limit rod 19 is fixedly installed on the inner wall of the mounting cavity 2, a limit plate 18 is slidably installed on the limit rod 19, and one side of the limit plate 18 is fixedly connected to the annular shell 3.

[0034] In this embodiment, the use of the arc-shaped foot buckle 17 can hold the actor's feet, thereby ensuring body stability. When the lifting platform 5 is lifting and rotating, it can prevent large-scale accidental swaying of the body. The use of the limiting rod 19 and the limiting plate 18 can further improve the stability of the annular shell 3, the support plate 4 and the lifting platform 5 during use, and prevent obvious shaking.

[0035] In summary, compared with related technologies, this solution, through the use of a protective mechanism, can raise the transparent protective cover 8 to a higher position when the lifting platform 5 raises the actor to a relatively dangerous height. The top of the transparent protective cover 8 can be higher than the lifting platform 5, gradually forming a transparent protective barrier around the actor. This effectively prevents the actor from falling off the stage due to instability during the performance, greatly improving the safety of the actor performing at heights. It effectively solves the technical problem that existing stage lifting devices lack height safety protection measures, which makes it easy for actors to suffer serious injuries from falling off the stage.
