Description

Technical Field

[0001] The present invention relates to the technical field of stage equipment, and more specifically to a turntable air-cushion vehicle for stage. Background Art

[0002] When the air cushion is inflated to a certain pressure, the operation of the device has almost no friction with the ground, and thus has the performance of shockproof, friction-proof and anti-static. The most important thing is that it saves effort, and the carrying force only needs 0.5 ten-thousandth of the load, which means that it only takes one kilogram of force to carry two tons of weight. On the stage, acrobats need to complete various difficult actions such as tumbling in the air and flying in the air, which all need to rely on props to complete. At the same time, moving or placing some key decorative heavy objects on the stage also relies on props to complete. Since air-cushion vehicles are particularly suitable for heavy loads that are not easy to move flexibly and large precision equipment that cannot withstand vibration and have high requirements for stability, air-cushion vehicles are often used on the stage. However, the existing air-cushion vehicles drag air pipes and cables, which will affect the movement path selection of the entire air-cushion vehicle and cannot be moved at will. At the same time, the stability of the existing air-cushion vehicles also depends on the stability of the center of gravity of the load. During the stage performance, the existing air-cushion vehicles cannot quickly adjust the direction of the load, resulting in a reduction in the stage performance effect and cannot meet the current stage performance needs. Summary of the invention

[0003] The purpose of the present invention is to solve the technical problem that the existing air-cushion vehicle cannot move arbitrarily and cannot quickly adjust the direction of the load. The present invention provides a turntable air-cushion vehicle for stage.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A turntable air cushion vehicle for stage comprises a rectangular platform, wherein installation cavities are provided at the bottom of the rectangular platform near the four corners, air cushions are arranged inside the installation cavities, all air cushions are connected to an air compressor fixed inside the rectangular platform, a driving mechanism is arranged at the bottom of the rectangular platform, the driving mechanism comprises a placement column slot provided at the center of the bottom of the rectangular platform, a rotatable rotating column is arranged inside the placement column slot, a movable cavity is provided at the center of the bottom surface of the rotating column, a retaining column which can only move up and down is arranged inside the movable cavity, a compression spring is provided between the top surface of the retaining column and the bottom surface of the movable cavity, a roller is provided at the bottom of the retaining column, the roller is connected to a first driving motor, a circle of movable card slots is provided around the center line of the placement column slot at the bottom of the rectangular platform, a movable movable block is arranged inside the movable card slot, a motor support rod is fixed at the bottom of the movable block, the first driving motor is installed on the motor support rod and can move up and down, a second driving motor is provided at the bottom of the rectangular platform, the second driving motor is connected to a rotating shaft, a bevel gear is fixed at the end of the rotating shaft, and the meshing controls the steering.

[0006] On the basis of the above technical solution, all air cushions are interconnected by air pipes arranged at the bottom of the rectangular platform, and all air pipes are connected to air compressors.

[0007] Based on the above technical solution, a plurality of support columns are arranged at the bottom of the rectangular platform, and the bottom surface height of the support columns is lower than the bottom surface height of the air cushion in the deflated state.

[0008] Based on the above technical solution, a battery box is arranged at the bottom of the rectangular platform, and the air compressor, the first drive motor and the second drive motor are all connected to the battery box.

[0009] Based on the above technical solution, two support plates supporting the entire rotating shaft are fixed at the bottom of the rectangular stand, and bearings are arranged between the rotating shaft and the support plates.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The present invention has a compact structure and a reasonable design. The entire air cushion vehicle is supported by four air cushions, which effectively improves the bearing capacity of the tire. At the same time, the air compressor is integrated, which completely replaces the method of connecting the external air compressor to the air pipe and the air pipe to the air cushion, solves the problem of the difficult handling of the dragging air pipe, and allows the entire air cushion vehicle to move at will. When starting the entire air cushion vehicle, firstly, the first drive motor is powered on. When the object is loaded, the air compressor is started to pass compressed air into the air cushion. As the amount of compressed air in the air cushion cavity continues to increase, the air pressure continues to increase, and the air cushion will slowly lift the entire rectangular platform and suspend it off the ground. At this time, the holding column continuously compresses the compression spring, so that the roller is always pressed on the road surface. The first drive motor further drives the roller to rotate, thereby driving the entire air cushion vehicle to move. When it is necessary to turn the load, the second drive motor is started, and the second drive motor drives the rotating shaft and the bevel gear to rotate, driving the entire rotating column to rotate in the column slot, thereby realizing the turning of the load during the movement, and the entire process of adjusting the turning is very rapid.

[0012] 2. In the present invention, the air pipe connects all the air cushions. When the center of gravity of the load is unstable, the air cushion can adjust the internal air pressure through the air pipe, so that the stability of the entire air cushion vehicle can be guaranteed at any time.

[0013] 3. In the present invention, on the one hand, the height requirement of the support column can ensure that the air cushion will not be squeezed when it is not inflated, and on the other hand, it can also improve the stability of the entire air cushion vehicle, thereby improving practicality.

[0014] 4. In the present invention, the battery box allows the entire air cushion vehicle to be free of electrical wiring, thereby further solving the problem of long electrical wiring being difficult to handle and further improving practicality.

[0015] 5. In the present invention, the support plate can improve the structural strength of the rotating shaft, avoid the rotating shaft being too long and resulting in low fatigue strength, thereby increasing the service life of the rotating shaft and further improving practicality.
