The present invention and embodiments relate to the field of stage performing arts device, and more particularly to a wireless remote control orbiter based on 5G frequency band.
An orbiter is a common device in venues for performing arts. The main function of the orbiter is to lift the actors or props for performing in air. Because general orbiter moves with towing wire rope, turning, twisting, and releasing of the cable used for power and control are difficult (easy to wound and interfere with each other), the rails are straight, and the route is relatively short, and the running speed is slow. So these orbiters only move in two-dimensional in a vertical plane. The artistic expression in the performing arts is very limited.
At least one technical problem to be solved by the present patent application is to provide a wireless remote orbiter based on 5G frequency band which can run smoothly with high speed, and low noise, realizing curve motion.
In order to solve the above problem(s), the present invention and its embodiments provides a wireless remote control orbiter based on 5G frequency band, the orbiter comprises a main rail which is fixedly mounted on a bearing beam of stage and a rack which is mounted with translational drive means and lifting drive means. The main rail comprises a vertical rail and a horizontal rail which is formed integrally below the vertical rail. Load-bearing wheels are fixedly mounted on the rack against the upper of the horizontal rail. Translational friction wheel groups are connected to the translational drive means against the vertical rail. The lifting drive means are connected to the hoisting mechanism. A sliding contact line is laid with the rail on the main rail, a collector supplied power from the sliding contact line conductor is mounted on the rack.
Wherein, the translational friction wheel groups comprise a main translational friction wheel which is mounted on the translational drive means, a first bearing pedestal for supporting the main translational friction wheel, a second bearing pedestal which is articulated on the first bearing pedestal and a driven translational friction wheel which is supported on the second bearing pedestal by bearing. The main translational friction wheel and the driven translational friction wheel separately lean against both sides of the vertical rail.
Wherein, a first tension spring is disposed between the first bearing pedestal and the second bearing pedestal.
Wherein, a plurality of horizontal stable wheel groups are disposed on the rack, each of the horizontal stable wheel group comprises two horizontal stable wheels which are movably mounted on the rack, the two horizontal stable wheels separately lean against both sides of the vertical rail.
Wherein, a horizontal affiliated rail is fixedly mounted on the main rail, a plurality of vertical stable wheels are disposed on the rack, each of the vertical stable wheel group comprises two vertical stable wheels which are movably mounted on the rack, the two vertical stable wheels separately lean against both sides of the affiliated rail.
Wherein, the orbiter further comprises a ranging mechanism. The ranging mechanism comprises a ranging synchronous belt which is fixedly mounted on the main rail, and a belt wheel which is meshed with the ranging synchronous belt, and a first encoder which is connected to the belt wheel. The belt wheel is movably mounted on the rack.
Wherein, a second tension spring is disposed on the rack. One end of the second tension spring is connected to the rack, and another end is connected to the belt wheel.
Wherein, a remote control signal receiver is disposed on the rack. The remote control signal receiver receives wireless signal on 5G frequency band.

A corner pulley 15 which can guide the wire rope of the hoisting mechanism is provided on the rack 1 to ensure the wire rope can hoist smoothly and thereby avoid getting stuck and so on.
As shown in
A first tension spring 65 is disposed between the first bearing pedestal 62 and the second bearing pedestal 63, so that the main translational friction wheel and the driven translational friction wheel always lean against both sides of the vertical rail.
A plurality of horizontal stable wheel groups are disposed on the rack 1, each of the horizontal stable wheel group comprises two horizontal stable wheels 4 which are movably mounted on the rack 1, the two horizontal stable wheels 4 separately lean against both sides of the vertical rail 21, so the longitudinal stability and security can be ensure when the hanging tool is high-speed running.
A horizontal affiliated rail 12 is fixedly mounted on the main rail 2. A plurality of vertical stable wheels are disposed on the rack 1. Each of the vertical stable wheel group comprises two vertical stable wheels 13 which are movably mounted on the rack 1, the two vertical stable wheels 13 separately lean against both sides of the affiliated rail 12, so the lateral stability and security can be ensure when the hanging tool is high-speed running.
The orbiter further comprises a ranging mechanism 14, as shown in
A second tension spring 144 is disposed on the rack 1. One end of the second tension spring 144 is connected to the rack 1, and another end is connected to the belt wheel 142, so that the belt wheel is always meshed with the ranging synchronous belt.
Of course, the ranging mechanism can be meshed with a chain or a sprocket, but noise is smaller when the belt wheel is meshed with the ranging synchronous belt.
A first limit switch 10 is separately mounted on the two ends of the rack 1 for preventing collision of the rack with other objects.
The hoisting mechanism 9 is a dual rope winch, namely dual wire rope can be used for lifting the hanging tool, so that the hanging actors or props can be stable and little shake and not spin. A hoisting limit block 17 is disposed on each of the hoisting mechanism. A second limit switch 16 is mounted above each of the hoisting limit block 17 on the rack 1 to prevent accidents which are caused by transfinite winding of the winch. The hoisting limit block 17 is also balancing weight of no-load to avoid rope winding due to spring-back of the wire rope when winch is no-load.
A second encoder is mounted on the drive motor of the translational drive means 7 to control rotation speed and lifting height of the drive motor in order to ensure lifting start-stop smoothly and locating exactly.
A remote control signal receiver and electrical control box 5 are fixedly mounted on the rack 1. The remote control signal receiver and electrical control box 5 are wireless connected with the upstage operating system, modular management can be realized, and the characteristics of good generality, portability, compatibility and so on can be realized. Because of using virtual devices to simulate running interface, graphical editing, storing scenes and automatic running, etc. can be realized, devices operating parameters can be immediately changed in the specific mode, and devices status can be real-time viewed.
The remote control signal receiver can receive the wireless signal of 5G frequency band, so the interference of wireless signal source in venues for performing arts 2G˜3G frequency band (such as wireless Wi-Fi®, mobile phone GPRS signal, wireless intelligent light, wireless microphone, walkie-talkie, etc.) can be effectively avoided, and it is ensured that the orbiter can be whole course controlled and run more securely and reliably.
