Description

Technical Field

[0001] This utility model relates to the field of performance stage props technology, and in particular to a combination device of a lifting and rotating screen and a follow-up lifting stage. Background Technology

[0002] As living standards continue to improve, audiences have higher and higher requirements for the effects of artistic performances. The stage, as an indispensable part of the performance, plays an important role in the performance effect.

[0003] Among the features, liftable stages and displays are common in existing stage performances. However, the lifting of existing stages and displays is done independently, requiring multiple lifting power systems, resulting in complex structures and high costs. In addition, the operation of displays and stages is limited, failing to meet diverse performance needs, thus having a narrow scope of application and failing to fully utilize equipment and space, leading to high operating costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a combination device of lifting and rotating screen and following lifting stage. It has a simple structure and uses a lifting power system to realize the lifting and lowering of the screen and two following stages.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A combined device for a lifting and rotating screen and a following lifting stage is located on a base, comprising one lifting and rotating screen and two lifting stages, symmetrically arranged on both sides of the screen. The lifting and rotating screen includes a fixed truss and an LED screen fixed to its surface. Each lifting stage includes a stage steel frame and a stage surface fixed to its top. The two sides of the fixed truss are rotatably connected to the stage steel frame via slewing bearings. The slewing bearing is a large bearing capable of withstanding comprehensive loads, simultaneously bearing large axial and radial loads and overturning moments. It includes an inner ring, an outer ring, and rolling elements between them. The outer ring is fixed to the stage steel frame, and the inner ring is fixed to the fixed truss, allowing the lifting and rotating screen to rotate between the two lifting stages. Preferably, the slewing bearing is located in the middle of the fixed truss surface to ensure balanced force distribution.

[0007] A lifting drive assembly is provided between the lifting stage and the base. The lifting drive assembly includes a lifting drive motor, a chain mechanism, a rigid chain, and several scissor forks. The lifting drive motor is connected to the chain mechanism. The rigid chain is located inside the chain mechanism and its upper end is fixedly connected to the stage steel frame. The upper and lower ends of the scissor forks are hinged to the stage steel frame and the base, respectively. Initially, the rigid chain is retracted inside the chain mechanism. When it needs to rise, the lifting drive motor drives the chain mechanism, causing the rigid chain to extend upwards, raising the two lifting stages and the lifting rotating screen. Simultaneously, the scissor forks unfold, their height changing synchronously with the lifting stages, providing support and stability. When it needs to descend, the lifting drive motor drives the chain mechanism, causing the rigid chain to return downwards, lowering the two lifting stages and the lifting rotating screen. Simultaneously, the scissor forks fold and retract, their height changing synchronously with the lifting stages.

[0008] Preferably, there is one lifting drive motor, located between the two chain machines. The two sides of the lifting drive motor are connected to the chain machines through drive shafts to realize the synchronous movement of the two lifting stages.

[0009] Preferably, a flip drive assembly is provided between the lifting and rotating screen and the lifting stage. The flip drive assembly includes a flip drive motor, which is fixed to the stage steel frame and is connected to the inner ring of the slewing bearing. Specifically, a gear is provided at the output end of the flip drive motor, and a gear ring that meshes with the gear is provided on the inner ring of the slewing bearing.

[0010] Preferably, there are two flip drive components, with the two flip drive motors fixed on the two stage steel frames respectively, and the two flip drive motors working synchronously.

[0011] Preferably, a flip drive assembly is provided between the lifting and rotating screen and the lifting stage. The flip drive assembly includes a flip drive motor and a flip shaft. The flip drive motor is fixed to the stage steel frame, and the flip shaft is located in the middle of the slewing bearing, with one end fixed to the fixed truss and the other end connected to the flip drive motor. In the initial state, the LED screen and the stage surface are on the same plane or parallel. When rotation is required, the flip drive motor drives the flip shaft to rotate, thereby realizing the rotation of the lifting and rotating screen.

[0012] Preferably, there are two flip drive components, with the two flip drive motors fixed on the two stage steel frames respectively, the two flip shafts located between the two slewing bearings respectively, and the two flip drive motors working synchronously.

[0013] The advantages of this utility model are: 1. Simple structure, using a lifting power system to realize the lifting of the screen and two following stages; 2. The combination of the flip screen and the stage can meet different performance needs, the stage performance scenarios are diverse, the application range is wide, and it can fully utilize the equipment and space in different states, saving operating costs.
