Platform for moving and positioning Target Spect r ometer on the floor

1. Workshop – September 2010 Platform for moving and positioning Target Spectrometeron the floor Cracow University of Technology Mechnical Design Group W. Czyżycki, M. Domagała, G. Filo,M. Hawryluk, E. Lisowski

2. 1. Airpads systems – moving and lifting 2. Air pads, only lifting, y axis Hilman Rollers moving along x axis plastic sliders z axis and two guidelines with two horizontal hydraulic cylinders. 3. Hydraulic jack for lifting (Enerpack system) , y axis Hilman Rollers mowing along x axis plastic sliders (z axis) and two guidelines with two horizontal hydraulic cylinders. Plan of thepresentation

3. Assumptions for construction of the platform: Platform, rails and another devices situated on the floor Target Spectrometer and his doors will be support by the platform Platform allows to move Target Spectrometer in x – axis direction and positioning in z axis and y – axis. • To makethemain assumptions

4. This construction of the platform give us three possibilities to movement: on DELU air pads Independly we can use special polymeric slippers without or with air pads The Hilman Rollers- for this we need steel rails on the floor and lifting system for positioning The construction of the platform includes standard long four I-beams HEB800 air supply hose slipper/support air pad hydraulic cylinder

9. Each 1220mmx1220mm Air pad • Air pads system Lifting hight 40 mm Lifting mass 8x45=360 tones at 4 bar Moving 8x40=320 ton Moving10x40=400 ton

10. Twenty plastic sliders under the platform • Izometricview 700mmx300mm Coeficient of the friction less than 0.08

11. Plastic sliders and air pads under platform • Izometricview

12. Eight or ten pads max load 400 tones The pressure will be controled in each path Double DELU system hose accessory, consisting of: • 12 piece connecting hoses each 5 m long, (2pcs reserve)with two female quick connection couplings each • 2 piece high flexible supply hose 30m long, diameter 2”with two female quick connection couplings each • 2 piece air connection point 2" with external thread AirConsumption 8 m3/min for one segment , pressure 4 bar, lifting 40 mm

13. FEM Analysis - shell model, constraints and load Mass of the target 300 ton, mass door 40 tons

14. I-BEAM Von Mises Stress less than 100MPa • FEM Analysis – von Misesstress

15. Displacement magnitude less than 0.5 mm • FEM Analysis - displacement

23. Workingin long distans on the Hilman Rollers • Precision positioningwithusing air pads and sliders Moving system with Hilman Rollers and air pads and plastic sliders

24. 150-XOTL 150-tons Thetype of rollers Top plate 356x813x25 mm Number contact rollers – 11, Roll diam. 49mm, width 92 mm, mass of one 172 kg • C = capacity of roller in metric tons W = weight of total load, converted to metric tons N = number of rollers to be used P = load Coefficient (from table for correctload)

30. Therange of themovingdistance Lifting platform, y axis on air pads or hydraulic jacks, range 5 mm Positionig, z axis on plastic sliders or air pads, range - 40 mm Hilman Rollers – x axis, range limited by lenght of rails

31. Contactpressure on thefloor Air pads – 0.315 MPa Plastic sliders – 0,857 MPa Hilman Rollers – 11,837 MPa Hydraulic Jacks – 40 MPa (Hilman Rollers pressure on floor by the rails)

32. Air pads platform with plastic sliders Advantages: Give possibility to move in three direction x,y,z No deformation of the structureand low stress Low contactpressure on floor and easycontrolpressureineachpads We don’t need to prepare channels in floor to mount (precisely machined) rails. Thesimple guidance for air pad platform can be mounted on floororwithoutit. We need the air pads only during moving, after that you can use the pads to move another load It is possible to exchange plastic sliders made of plastic into steel ones if theTarget Spectrometer not move long time. Lowfrictionduringmoving Delivery no problem, a few company produceit. Disadvantages: Thereisnecessary to use a big compressor, We needflatfloor, Canapear a noiseifthefloor will not be polishorwavy. Summary air pads

33. Advantages: We needonlyfourblock of Hilman Rollers Hilman rollersseems me cheaperthananothersolution but ifyoutakeconsiderationadditionalsupport devices wich be necessary to useprobablytheprice will be similar Summary Hilman Rollers Disadvantage: Movingonlyalongx-axis We needtwo heavy rails and guidance For positionig z axis we needanother devices For positionigin y axis we needhydraulicorpneumatic system Problem to assureequalpressure under eachrollers We need big Rollers so Hilman don’tproduce for thisguildelinerollers Construction of therails and guidanceis not simpleus for air pads Deliveryonly one Company

34. 1.Each solution to move Target spetometer will be expensive 2. Each solutions is expensive but cheaper than on wheel carriage 3.None of solutions: Hillman and air pads don’t allow to move automaticly Target Spectometer from park to domestic position Summary
