Description

Technical Field

[0001] The invention relates to the technical field of stage lifting platforms, and in particular to a tabletop tilting driving device of a stage lifting platform. Background Art

[0002] The stage is a special area in buildings such as theaters, auditoriums, and performance venues for actors to perform. The stage is a carrier of performing arts. It provides a space for actors to showcase their works. Actors interpret roles and storylines through body movements, language, and facial expressions on stage. The stage works closely with elements such as lighting and sound to create a complete performance effect.

[0003] The stage deck tilting drive device can drive the stage deck to tilt. By reasonably adjusting the tilt angle of the stage lift deck, audiences in different positions can have a better viewing experience. Moreover, in many stage performances, such as dramas, operas, ballets, etc., various terrains can be simulated by tilting the deck.

[0004] Considering the existing table top tilting driving device, one end of the table top is usually set as the rotation center, and the stage table top is thicker, and the gap between the stage table top and the pedestal is smaller. Therefore, when the stage table top rotates and tilts around the rotation center, the bottom end of the table top close to the rotation center is prone to contact and squeeze with the pedestal, causing damage to the pedestal and the table top. Therefore, before the stage table top is tilted, the table top needs to be lifted upward by another lifting equipment to avoid squeezing with the pedestal when the table top is tilted, thereby reducing the work efficiency and use effect of the stage.

[0018] Reference Figures 1 to 4 The tabletop tilting driving device of the stage lifting platform shown in the figure includes a pedestal 1, a tabletop 2, a lifting mechanism 3, an adjusting mechanism 4, a plug-in mechanism 5 and a buffer mechanism 6. A through slot for the adjusting mechanism 4 to move is provided on the top of the pedestal 1. The tabletop 2 can be rotatably mounted on the adjusting mechanism 4. The lifting mechanism 3 is fixedly mounted on the inner side of the pedestal 1. The lifting mechanism 3 is used to drive the adjusting mechanism 4 to move vertically, and the lifting mechanism 3 can also drive the plug-in mechanism 5 to move horizontally. The adjusting mechanism 4 is used to drive the tabletop 2 to move vertically or rotate. Through the adjusting mechanism 4, the tabletop 2 can be tilted during the movement, thereby avoiding the squeezing of the tabletop 2 and the pedestal 1, improving the work efficiency of the stage, and at the same time, the tabletop 2 can be driven to move vertically and adjust the horizontal height of the tabletop 2. The plug-in mechanism 5 is fixedly mounted on the adjusting mechanism 4. The plug-in mechanism 5 is used to adjust the movement state of the adjusting mechanism 4. By adjusting the movement state of the adjusting mechanism 4, the movement state of the tabletop 2 can be adjusted, so that the use effect of the tabletop 2 is improved.

[0019] Reference Figures 8 to 10The adjustment mechanism 4 includes a moving plate 41, a moving rod 44 and a support rod 47. The moving plate 41 can be slidably installed on the inner side of the pedestal 1. The sliding effect of the moving plate 41 can drive the support frame 42 and the moving rod 44 to move vertically. The moving plate 41 is connected to the table 2 through the support frame 42. The support frame 42 supports one end of the table 2. The support frame 42 is rotatably connected to one end of the table 2. The moving effect of the support frame 42 can drive one end of the table 2 to move vertically. The moving rod 44 drives the table 2 to rotate through the hinge rod 46. The vertical movement effect of the moving rod 44 makes the hinge rod 46 drive the other end of the table 2 to move vertically. The two ends of the hinge rod 46 are respectively hinged to the moving rod 44 and the table 2. The horizontal movement effect of the moving rod 44 makes the hinge rod 46 drive the table 2 to rotate around the support frame 42. A slide groove 49 is provided on the support rod 47, and the support rod 47 and the hinge rod 46 are connected by a connecting column 48. The connecting column 48 slides along the inner side of the slide groove 49, and the support rod 47 supports the hinge rod 46 to improve the stability of the hinge rod 46.

When the plug block 52 is plugged into the housing 53, the T-block 55 and the T-slot 54 are disconnected, and the housing 53 can drive the plug block 52 to move horizontally, thereby driving the movable rod 44 to move horizontally. The T-block 55 is plugged into the inner side of the T-slot 54. When the T-block 55 and the T-slot 54 are plugged into, the plug block 52 is disconnected from the housing 53, thereby keeping the movable rod 44 fixed. The housing 53 is fixedly mounted on the lifting mechanism 3, and the lifting mechanism 3 is used to drive the housing 53 to move horizontally.

[0022] Reference Figures 4 to 6 The lifting mechanism 3 includes a motor 31, a threaded rod 32, an H-shaped rod 33, a threaded sleeve 35 and a threaded column 37. The motor 31 is fixedly installed on one side of the pedestal 1, and the threaded rod 32 can be rotatably installed on the inner side of the pedestal 1, and the threaded rod 32 is fixedly connected to the output shaft of the motor 31. The threaded rod 32 is driven to rotate by starting the motor 31. The H-shaped rod 33 is threadedly connected to the threaded rod 32. The rotation effect of the threaded rod 32 drives the H-shaped rod 33 to move laterally. The H-shaped rod 33 is connected to the pedestal 1 through a guide rod 34, and the H-shaped rod 33 can be slidably installed on the guide rod 34. The guide rod 34 guides the H-shaped rod 33 to prevent the H-shaped rod 33 from deviating when moving.

[0023] Reference Figures 5 to 7The H-shaped rod 33 drives the threaded sleeve 35 to rotate through the mutually meshing rack 38 and gear 36. The gear 36 is driven to rotate by the movement effect of the rack 38. The rack 38 is fixedly mounted on the H-shaped rod 33. The rack 38 can be driven to move by the movement effect of the H-shaped rod 33. The gear 36 is fixedly mounted on the threaded sleeve 35, and the threaded sleeve 35 is rotatably mounted on the inner side of the pedestal 1. The threaded sleeve 35 can be driven to rotate by the rotation effect of the gear 36. The threaded column 37 is connected to the inner thread of the threaded sleeve 35, and the threaded column 37 is fixedly connected to the bottom of the movable plate 41. The rotation effect of the threaded sleeve 35 can drive the threaded column 37 to move vertically, thereby driving the movable plate 41 to move vertically. The top of the H-shaped rod 33 is fixedly connected to the shell 53. Two H-shaped rods 33 are provided. The shell 53 is provided on the H-shaped rod 33 close to the motor 31. The shell 53 can be driven to move through the movement effect of the H-shaped rod 33 close to the motor 31.

[0024] Reference Figure 8 The buffer mechanism 6 includes a cylindrical tube 61, a spring 62 and a resisting column 63. The buffer mechanism 6 is distributed in an array of four groups. The cylindrical tube 61 is fixedly installed at the bottom of the movable plate 41. One end of the spring 62 is fixedly connected to the inner side of the cylindrical tube 61, and the other end of the spring 62 is fixedly installed on the resisting column 63. Through the elastic force of the spring 62, the resisting column 63 always keeps moving downward without being affected by external force. When the resisting column 63 contacts the base 1, it will squeeze the spring 62 and thus play a buffering role on the movable plate 41 and the table 2. The resisting column 63 can be slidably installed on the inner side of the cylindrical tube 61.

[0025] The tilting drive device of the stage lifting table top, through the provided lifting mechanism, adjusting mechanism and plug-in mechanism, enables the H-shaped plate to drive the movable plate to move upward during the movement, and drives the movable rod to move at the same time, so that the table top can be tilted during the vertical movement, thereby improving the work efficiency and use effect of the stage. At the same time, the movable rod is limited by the plug-in mechanism, so that the lifting mechanism and the adjusting mechanism can drive the table top to always move vertically or perform lifting and tilting movements, thereby improving the use effect and functionality of the stage. In addition, the provided buffer mechanism allows the table top to play a buffering role during the descent process, thereby improving the service life and safety of the stage.
