Description

TECHNICAL FIELD

[0001] The utility model relates to truss field, more particularly, to a rotatable truss type stage device. BACKGROUND

[0002] In modern stage performance and large-scale activities, the rotating stage is widely used due to its unique effect. The complex structure and a large number of connecting components of the existing rotating stage result in its large size, and the use of a large amount of metal material results in its heavy weight, which occupies a large space and needs to borrow special transport tools, so the transportation is extremely inconvenient. In addition, the large size also increases the difficulty of installation and disassembly, which needs to consume a large amount of manpower and time. The heavy rotating stage also has higher requirements for the rotating structure, and the gravity and friction force increase accordingly. If the design is improper, the rotating structure will not run smoothly, and the phenomenon of jamming is easy to occur, which seriously affects the performance effect and audience experience. SUMMARY

[0004] To solve the above technical problems, the utility model adopts the technical scheme: a rotatable truss type stage device is provided, which comprises a base, a support truss pivotally connected to the base, and a driving motor for providing driving force. Under the driving of the driving motor, the support truss rotates around its rotation center relative to the base. A plurality of rotating wheels are located between the base and the support truss to support the support truss, and the rotating wheels are distributed around the rotation center of the support truss.

[0005] The plurality of rotating wheels provide sufficient support force to the support truss and allow it to rotate relative to the base. When the base is installed on other planes, the rotation of the support truss is more smooth and stable under the driving of the driving motor. The support truss can be installed with various lamps or other stage props, and the rotating motion is coordinated to make the overall effect more lively and rich.

[0006] Further, the plurality of rotating wheels are distributed around the same circumference. The stress of the support truss is more uniform, effectively ensuring smooth rotation.

[0007] Further, the rotating wheels are fixedly connected to the base through mounting brackets, and the rotating wheels abut against one side of the support truss close to the base. The mounting brackets make the rotating wheels more firmly connected to the base, and the height of the rotating wheels can be adjusted through the mounting brackets.

[0008] Further, the support truss is provided with a horizontal adjusting plate on one side close to the base, the rotating wheel is abutted against the support truss through the horizontal adjusting plate, and the rotating wheel slides on the surface of the horizontal adjusting plate under the driving of the driving motor. During the rotation of the support truss, the horizontal adjusting plate enables the rotating wheel to slide on a relatively flat surface, the pulley is not easy to deform, and thus the support truss can rotate stably.

[0009] Further, the horizontal adjusting plate is provided with a guide rail for guiding the sliding direction of the rotating wheel, so that the positioning of the support truss during the rotation is more accurate, and the abrasion caused by the movement deviation of the rotating wheel is reduced.

[0010] Further, the support truss comprises a circular ring formed by splicing arc-shaped supports and a connecting base located at the center of the circular ring, and further comprises a connecting truss for connecting the circular ring and the connecting base. The splicing mode is favorable for storage and transportation, and the connecting truss strengthens the connection between the arc-shaped supports.

[0012] Further, the center of the support truss is provided with a connecting plate for connecting with the driving motor, and further comprises a plurality of auxiliary wheels arranged around the rotation center of the support truss, which are fixedly connected to the base and abut against the connecting plate. For a stage device with a larger area, the auxiliary wheels further strengthen the support of the support truss, so that the stress is more balanced and the middle part is prevented from collapsing.

[0013] Further, the support truss is provided with a panel on the side away from the base. The panel makes the surface of the support truss flat, which is favorable for mounting various lamps or other stage props or for workers to stand on the panel to work.

[0014] Further, the base comprises a plurality of support rods which can be spliced with each other. The overall weight is reduced, and the base is convenient to disassemble, so that storage and transportation are further facilitated. BRIEF DESCRIPTION OF DRAWINGS
