Weak current College】 【stage mechanical design with the General principles.

<br> <br> The stage machinery of the design, manufacture, inspection and acceptance should be in line with China's existing relevant standards and regulations. <br> <br> 1. the stage machinery design stage machinery must be considered before use in .various weather conditions: temperature, humidity. Air temperature: -25?? 40 ° c, relative humidity of 5%?? 100%. <br> 2. working environment conditions for temperature: 0?? 40 ° c, relative humidity ≤ .80%. <br> 3 all devices are available for stand-alone operation, can realize logic combined. Combined at run time, when a stand-alone operation or multiple stand-alone run-time, with each other to interfere or damage the .device, the device runs interlock. <br> 4. the equipment operation can console (Board), you can also manually. <br> 5. power requirements: 50HZ: 380vac, voltage fluctuations-15% to + 10; <br> .<br> THD rate power: 380V <5%. <br> 6. equipment positioning and synchronization accuracy: <br> <br> Booms positioning accuracy of ± 5mm, synchronization accuracy is ± 10mm <br> II. Implementation and reference .standards and specifications <br> <br> 1. the owners determine construction drawings, after the tender, tender answering: <br> 2. the frame of the basic requirements of the stage <br> 3. the theatre building design code JGJ57- .2000 (J67-2001) <br> 4. test the textiles flammability oxygen index Act GB/T5455-1997 <br> 5. the vertical flammability test of textile Act GB / T 5455-1997 ⑦ grounding device installation and acceptance <br> .6. the cable line construction and acceptance <br> 7. electrical equipment installation engineering construction and acceptance <br> 8. the stage and television with Suspender device "<br> 9. the stage with a mechanical device on the curtain rose <br .> Third, the design principles <br> 1. the stage machinery parts standardization and universal as possible <br> 2. all materials must be new, material quality should comply with the relevant standards: <br> 3. the stage machinery should be .designed to take into account the general maintenance of the simple and quick temporale into consideration lubrication of moving parts: rope, chain, zero Pak adjustments and inspection; <br> 4. electronic equipment control devices should be easy to maintenance, do not remove the .installation parts you can replace any damaged parts; <br> 5. the equipment design, should take full account of the on-site installation fast and efficient; <br> 4, safety design <br> <br> 1. physical security < .br> Access the actor and play area should install video surveillance equipment to monitor the signal needs to be sent separately to the master station and Director room. All mechanical, electrical and control system should be auto-protect, all from the normal channel of access .to the device's mobile or rotation of parts of the protective device shall be set up; all equipment shall meet the appropriate safety standards and procedures, in compliance with the safety and health requirements; all wires, cables should be fire-resistant, flame-retardant .or low smoke type. All runs are set under the emergency shutdown system; lifting equipments, in all possible solemnly produce shear pressure foot of occasions, the staff shall be set on the edge of the safety switch; <br> 2. the safety factor .<br> General machinery parts: all General machinery parts in preliminary discussion of the safety coefficient calculation should be greater than or equal to 5. Security system that is defined as the material limit stress to the maximum operating stress ratio. Working conditions should take account .of the maximum load and dynamic load (emergency braking, collision, etc.) produce stress. Wire rope for lifting or hoisting heavy wire rope safety factor should be equal to or greater than 10. Safety factor is defined as wire rope breaking force and the .maximum working load, acceleration and deceleration of dynamic loads and equipment, steel wire steering the additional load. Wire rope safety factor is used for lifting or hoisting heavy wire rope safety factor should be equal to or greater than 6. <br> 3. safety .devices and standby system <br> Various types of equipment must be protected with overtravel. Lighting crossing the bridge is equipped with overload detection device, hoisting 1.2 times rated weight will stop the running boom. If the console fails, you must have in the control .cabinet for manual operation. <br> <br> <br> <br>.
