Description

Technical Field

[0001] This utility model relates to the field of performance stage props technology, and in particular to a rotating performance device with multiple independently lifting and lowering units. Background Technology

[0002] As living standards continue to improve, audiences have higher and higher requirements for the effects of artistic performances. In order to enhance the viewing experience, many stage performances include aerial performances.

[0003] However, existing aerial stage performances generally only involve performers performing on an aerial stage. The aerial stage equipment itself is often very simple, with only a single lifting function and not many functions that can enhance the performance effect. In addition, the aerial performance equipment is often unable to move in the air or has a very simple trajectory for movement in the air, or cannot realize multiple actors performing in the air at the same time, resulting in poor viewing experience. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-set independent lifting and lowering rotating performance device that can be used for multiple actors to perform rotational and lifting movements in the air, thereby realizing multi-dimensional positional changes of multiple actors in the air.

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

[0006] A rotating performance device with multiple independently lifting and lowering components includes a fixed truss, a rotating truss, a number of rotating components, and a number of lifting components. The fixed truss is fixed to the top of the performance stage, and a number of first supports distributed equidistantly in a circle are fixedly installed at the bottom of the fixed truss. Hanging wheels are installed at the bottom of the first supports. The rotating truss is located below the fixed truss, and its top is fixedly equipped with a concentric annular hanging track and an annular friction track, with the annular hanging track suspended from the hanging wheels. The rotating truss and the fixed truss are rotated together via the annular hanging track and hanging wheels.

[0007] The rotating assembly is fixed to the fixed truss and is equidistantly distributed in a circular pattern. It includes a rotary drive motor and a rotating friction wheel connected by a transmission. One side of the rotating friction wheel abuts against the annular friction track. When the rotary drive motor operates, it drives the rotating friction wheel to rotate. The annular friction track rotates due to the frictional force exerted by the rotating friction wheel, thereby realizing the rotation of the rotating truss and its structure.

[0008] The lifting assembly includes a lifting winch unit, a steering pulley, and a suspension pulley fixed to the rotating truss. A traction rope wound around the lifting winch unit passes sequentially through the steering pulley and the suspension pulley before vertically downwards through the rotating truss. The lower end of the traction rope is connected to the performer. The lifting winch unit operates to raise and lower the traction rope, enabling the performer to rise and fall. In conjunction with the rotating assembly, it allows the performer to rotate in the air.

[0009] Preferably, the rotating assembly further includes a radial clamping wheel fixed to the fixed truss, the radial clamping wheel abutting against the opposite side of the annular friction track relative to the rotating friction wheel. The rotating friction wheel and the radial clamping wheel are located on opposite sides of the respective annular friction tracks, ensuring that the rotating friction wheel always abuts against the annular friction tracks, effectively driving the annular friction tracks.

[0010] Preferably, the radial clamping wheel is fixed to the fixed truss by a gap adjustment assembly. The gap adjustment assembly includes a mounting base, a sleeve, a stud, and a compression spring. The mounting base is fixed to the fixed truss, and the radial clamping wheel is fixed to the sleeve. A fixed block is provided at one end of the sleeve, and a sliding block is provided at the other end. One end of the stud is fixed to the fixed block, and the other end passes through the sliding block and is fixed to the mounting base. The compression spring is sleeved on the stud, and its two ends abut against the fixed block and the sliding block, respectively. When the rotating friction wheel and the radial clamping wheel wear within a certain range, the gap with the annular friction track can be eliminated by the gap adjustment assembly, ensuring effective drive, extending the service life of the entire friction system, reducing operating costs, and simplifying the equipment adjustment process.

[0011] Preferably, there are two sleeves, and correspondingly two studs and two compression springs, with the radial clamping wheel fixed between the two sleeves.

[0012] Preferably, the fixed truss is annular, the rotating truss is annular, and the lifting assembly is circumferentially distributed on the rotating truss.

[0013] Preferably, the annular suspension track has a side-mounted H-shaped cross-section, i.e., H-beams can be used. Alternatively, the annular friction track can have an L-shaped cross-section, with its bottom horizontal section fixed to the top surface of the annular suspension track and its vertical section used for friction drive.

[0014] Preferably, the first bracket has two hanging wheels at its bottom, which abut against the lower ends of the two sides of the flange of the annular hanging track.

[0015] Preferably, a certain number of second supports are fixedly installed at the bottom of the fixed truss in a circularly distributed manner at equal intervals. The bottom of the second support is provided with two radial retaining wheels, which abut against the two sides of the middle section of the annular suspension track, respectively, to ensure that the annular suspension track always moves along the same trajectory.

[0016] The advantages of this invention are: it can be used for multiple actors to perform rotational and vertical movements in the air, enabling multi-dimensional positional changes of multiple actors in the air, enhancing the viewing experience of actors showcasing the charm of the story, and creating an immersive atmosphere for indoor performances.
