Workshop project from June 2010 at Cracow University of Technology. Mechanical design group developed a platform for moving and positioning the Target Spectrometer without surface grooves. The platform offers three movement options using DELU air pads, polymeric slippers, and Hilman Rollers. The construction includes I-beams, air support systems, and hydraulic cylinders for accurate positioning. Removable components like roller guides and hydraulic actuators enhance flexibility. FEM analysis ensured structural integrity under load and stress control. The platform design allows movement in x, y, z directions with minimum deformation and low floor pressure. The platform system can be easily adapted for different loads and conditions.

Workshop – June 2010 Platform for moving and positioning Target Spectometer without any groves in the floor Cracow University of Technology Mechnical Design Group W. Czyżycki, M. Domagała, G. Filo,M. Hawryluk, E. Lisowski
Target spectometer • Target Spectometer with the moveable platform and Muon Filter, which is not moveable Muon Filter Platform Fudamental Guide line
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

Each 1200mmx1200mm pipe Air pad • Air pads system Lifting hight 40 mm
Twenty plastic sliders under the platform • Izometric view 700mmx300mm Coeficient of the friction less than 0.08
Removeable plastic sliders and air pads under platform • Izometric view
Positioning – guide line and fix points End fix point Guide line with bolts at the floor
It is posssible move Target Spectometer usinig four blocks of the Hilman Rollers. The Hilman Rollers could be located between I-beam so construction can be the same us for pads and sliders. It gives possibility to move only in one direction. The positiong x, z – direction will be huge challenge for this solution • The construction with Hilman Rollers Rollers
Contact pressure on the floor Air pads – 0.315 MPa Plastic sliders – 0,857 MPa Hilman Rollers – 11,837 MPa (Hilman Rollers pressure on floor by the rail)
FEM Analysis - shell model, constraints and load Mass of the target 300 ton, mass door 40 tons
I-BEAM Von Mises Stress less than 100MPa • FEM Analysis – von Mises stress
Displacement magnitude less than 0.5 mm • FEM Analysis - displacement
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
Air pads platform with plastic sliders Advantages: Give possibility to move in three direction x,y,z No deformation of the structure and low stress Low contact pressure on floor We don’t need to prepare channels in floor to mount (precisely machined) rails. Guidance for air pad platform can be mounted on floor. 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 Spectometer not move long time.
