Description

Technical Field

[0001] The utility model relates to the technical field of performance prop devices, in particular to a liftable underwater flip stage. Background Art

[0002] With the continuous improvement of living standards, audiences have higher and higher requirements for the effects of artistic performances. The stage, as an indispensable part of the performance supporting facilities, plays an important role in the performance effect.

[0003] Among them, stage performances in real waters are becoming more and more common, but the problem is that the water level of real waters is subject to large seasonal changes, and the utilization rate of the stage is low, resulting in poor economic benefits. At the same time, the stage form in the waters is single and difficult to change, which cannot meet the diversified needs of the performing arts market.

[0004] In addition, in engineering, the device that connects a structure or component to a support is called a support. Among them, the hinge support is a commonly used basic component with a wide range of applications. It is often used in the design and manufacture of objects for connection, support or stability. The main feature is that it allows components to rotate at the connection while preventing them from separating from each other. In different application scenarios, hinge supports play an important role.

[0005] The problem with the existing hinge supports is that, although they can rotate, they cannot move in the vertical direction, which limits their application scenarios and scope of application. Utility Model Content

[0006] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art and provide a liftable underwater flip stage. The stage as a whole can be lifted and lowered to adapt to the seasonal changes in the water level in the real water area, increase the utilization rate of the stage, and improve the economic benefits. At the same time, the stage is provided with a flipping function to realize the projection function of the stage, which can further enrich the creation of the plot atmosphere of the real water area and improve the viewing experience of the program.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A liftable underwater flip stage includes a certain number of underwater bases, at least one set of hinge support lifting components, a flip stage steel frame and a stage flipping component. A base steel frame is fixedly mounted on the underwater base, and a plurality of pairs of load-bearing wheels are arranged on the base steel frame.

The lifting column rises until the rollers reach the upper plane of the ramp board. The hinge support and the flip stage steel frame on it are in the highest position. To lower, just reverse the operation. When the steel frame of the flip stage is flipped, the winch works to pull back the traction rope, and the traction rope pulls the lifting rope wheel and the lifting support arm to move upward. The steel frame of the flip stage is flipped upward along the hinge support at the end to a certain angle and is in an inclined state. If it does not flip, just reverse the operation. The lifting and flipping of the steel frame of the flip stage can meet different water levels and performance requirements.

[0012] Preferably, the guide column is square, and the first guide wheel group includes a middle guide wheel and two side guide wheels, which are respectively against three surfaces of the guide column to play a role of limiting guidance when the lifting column is raised or lowered.

[0013] Preferably, the number of the guide columns is two, which are located on both sides of the lifting column, and the number of the corresponding first guide wheel groups is two.

[0014] Preferably, the guide bracket is provided with two sets of second guide wheel groups facing each other and two sets of third guide wheel groups facing each other, which are respectively against four sides of the lifting column to ensure the stability of the lifting column when it is lifted or lowered.
