】 【Weak current College on stage machinery system design plan.

<br> <br> Summary: the stage machinery is the stage equipment of backbone is the cinema at the play an important part of the Church, on stage and screen, stage lighting design plays a vital role in the stage machinery design! have a .direct impact on the overall effect of the stage, he is like a building Foundation! and stage machinery design and safety also has a lot to do, the stage machinery mainly composed by sloat - curtain hanger, light boom and scenery boom! <br .> <br> Stage hanging tender is divided into two types of electric and manual, it is mainly used for suspension and lifting various curtains, lamps, scenery, etc, is a frequent mobile machinery around, so the security boom is also a major factor .of the stage. Booms role can reduce the labor intensity of the work, up to a multiplier effect, if a stage is 14 meters of depth, we can set the booms for him 38 road 24 Road King rod (including a front curtain), .14 road spare suspenders 【including 2-d side road light bracket products】, lifting movie screen frame, 1 road lighting crossing bridge and endless uniform expansion starts machine 1 set. <br> <br> So here the stage machinery of specific parameters: .<br> <br> A, scenery Suspender technical parameters are as follows: <br> Motor power: 2.2KW hanging points: 4 <br> Lifting speed: 0.27m / s provisional pole body length: 16 m <br> Motor speed .: 1400 rpm speed ratio: 40: 1 <br> Lifting load: 400KG rod for steel pipe <br> Control mode: point control <br> This type of crane, with upper and lower limit with recoil protection devices. Brake type: worm ., worm self-locking, electromagnetic brake. Noise ¡ .ü 45dB. <br> Hanger rod with two Φ 50 black mild steel tube welding into boom, intermediate connector-lined pipe. Finally all brush antirust paint twice, outer spray black paint. <br> B, light boom technical parameters are as follows .: <br> Motor power: 3KW hanging points: 4 <br> Lifting speed: 0.18m / s provisional pole body length: 14 m <br> Motor speed: 1400 rpm speed ratio: 50: 1 <br> Lifting load: 600KG .rod to 50 black pipe hangers <br> Control mode: point control <br> The upper and lower limit, Suspender with recoil protection devices. Brake type: worm, worm self-locking, electromagnetic brake. Noise ¡ .ü 45dB. <br> Hanger Rod used Φ 50; black mild steel tube welding into boom, intermediate connector-lined pipe. Finally all brush antirust paint twice, outer spray black paint. <br> <br> Stage machinery design principles <br .> <br> (Extract) 1, steel structure <br> <br> All load-bearing a) of the steel structure, its structural stiffness is greater than 1: 1000 <br> B) steel structure should design reasonable, the steel .structure and its connector should be able to withstand the maximum rated load and by the emergency shutdown caused by shock loads; <br> C) steel structure material shall meet the relevant standards; <br> D) steel weld shall comply with the relevant provisions ., mainly welds should be checks for non-destructive testing; <br> <br> 2, crane and hoisting equipment <br> <br> ① hoist winch on the motor and brake should be joint action, only the motor power is switched on ., you can open the license; in case of brake actuators and motors does not open when it's plugged in, but not the suspenders (load) a still or slow decline; <br> <br> ② Web components <br> ※ The reel .diameter not less than 30 times the diameter of the wire-rope; <br> ※ Reel with high-quality welding cast iron or thick-walled seamless steel tube and precise mechanical processing; <br> ※ Rope Island drum Groove centreline angle should be .at 2.5 degrees; <br> ※ Web components should be designed to prevent the rope in load or relaxation State job hopping. ③ pulley <br> ※ The pitch diameter of the pulley, should not be less than the diameter of the wire rope; .28 times <br> ※ The pulley and the pulley block bearing should be used; <br> ※ Pulleys and weights should prevent the rope from slot protectors. <br> ※ The rope and pulley of the deflection angle of not more than 2.5 degrees .. <br> <br> ④ rope <br> ※ Suspension rope should be a core with man-made fibres; soft rope <br> ※ Advance inspection: the availability of all wire rope shall be tested in batches; <br> ※ .The scene: wire rope should be careful during installation, cannot in any way technical tying or damage; damage or deformation of steel wire rope not receive. All cut off the head should be properly addressed; <br> * Installation: steel wire should not .be fixed with the device or mobile part of friction, the risk of damage or stuck, the correct protective measures to be taken; <br> ※ The suspension bearing: across the top of the steering wheel or in other places where flying rings, wire .rope should be supported on the pulley. <br> <br> ⑤ wire rope accessories <br> ※ Wire rope accessories should adopt galvanization of standard accessories; <br> ※ Wire rope accessories specification size and wire rope match; <br> ※ .Using rope clamps, each connector will use at least three correct installation of the rope clamp. <br> <br> 3, suspenders <br> <br> A hanger using tubes) or truss rod, tube or structure should be straight, not .distorted; <br> B) tube bar made of high quality seamless steel tube manufacturing; <br> C) Rod connector should be minimal, the connector uses the filled circle bars and pipes; <br> D) suspension rope's end with a single .installation to bar adjustment device adjustments; <br> E) tubes: pipe end should be equipped with eye-catching color permanent plastic caps or steel head; <br> <br> 4, spacing, positioning, overtravel switch <br> <br .> A) spacing and positioning switch <br> I. trip terminates the limited were <br> Switch: stroke end limit switch should be able to detect the equipment normal travel lock and parking; <br> Ii. the intermediate position switch: in .a suitable place to configure the intermediate position switch and deceleration switch; <br> Iii. direct collision limit openOff: stroke end limit switch can also be selected directly impact limit switch. <br> <br> B) overtravel limit switch <br> .Overtravel limit switch: all electric equipment should be installed on separate overtravel limit switch to prevent stroke end limit switch failure cause mechanical damage. <br> <br> 4. motor <br> <br> A) work cycle: stage machinery set by .intermittent operation. Each work cycle provided for in the load conditions 6 full itinerary stops running and 15min; <br> B) motor model: stage machinery, device, using the first brand in Shanghai Yuejin Motor. <br> C) power factor: .all motor power factor should be greater than or equal to 0.85. <br>.
