SEGMENT LIFTING JACK &LIFTING TALON



Lifting JackSegment Lifting Jack:– Function:

Raise and lower the MSA into and out of M1 array in a safe controlled mannerPrevent glass hitting glass during Installation & Removal (I&R)Compatible with crane and lifting talon operational sequencesCompatible with registration system

– Handoff without binding or overload

Light weight, simple, easy to operate, idiot-proof

– Requirements:Stroke 300 +/-2mm (increased over DRD reqt. (150mm) by agreement with Project)Lateral motion <0.5mm, Rotational motion: d < +/-0.5mm at vertex (DRD)

– See Jacking Gap Budget

Time for motion <1.0 minutesMaximum force applied < 1.5X weight of assembly being liftedTime for segment Removal and Installation 30 minutes

– ParametersFull extension at +300mmArray insertion at +95mm jack position (45mm mirror thickness+50mm sensor)Begin registration alignment at +10mm


Lifting JackThree jacking phases– Above Array - Coarse position control

Jack position: +100 to +300 mm

Segment is above adjacent segments – nothing to hit

– Array Insertion - Tight position controlJack position: +10mm to +100mm

Segment inserting into array

Adjacent segment 2.5mm away (nominal edge gap)

– Registration – Relaxed clocking controlJack position: 0 to +10mm

Allow registration system to position MSA


Segment Lifting JackSegment Lifting Jack Operations:– Raised 300mm– MSA placed on jack– Lowered onto Subcell

Segment Lifting JackThree-Part Jack System– Removable Center-Shaft installs in fixed frame bushings

Stiff accurate control of segment

Shaft engages with moving frame– 6DOF control

Controlled clearances to permit PMA self-alignment on registration features– Shaft to moving frame clearance 0.5+/-.25mm on diameter– Permits small radial, tip/tilt and clocking motion

– Removable Motorized Screw JackMotor driven Trapezoidal Screw

– will not back-drive– motor circuit be sized to stall or shutoff at max design load (current)– bolts to fixed frame, self-aligns to center shaft

– Permanently installed Clocking PinAttached to fixed frame

Provides required clocking accuracy during array insertion (close tolerance)

Segment Lifting JackSummary– Design concept meets requirements

Gap budget is tight

Glass-to-glass impact will likely occur during earthquake– protect segment corners with Kapton tape as a minimum

Jack motor type needs to be agreed upon


Lifting TalonLifting Talon CONCEPT Design– Requirements:

Safety: FSy > 3.0 for 2g load

Fail-safe (segment cannot be dropped)

Interlocked to assure mate to moving frame

Accommodate 14.5 deg inclination range (tip/tilt adjustment)

– Crane Assumption: Crane accurate to +/-5mm all directions

Crane can move Talon in direction normal to optical surface for segment installation & removal


Lifting TalonLifting Talon:– Talon claws motorized

Low torque motor for safety

Claw pivot point in-board of contact point– self-closing

Interlocks– Open/closed positions

– Moving frame capture (3)

– Vertical contact: moving frame-to-claw (3)

– Talon instrumentedLoad cell with 5N resolution

– to sense segment weight during handoff

– Tip/Tilt adjustableSet to match segment inclination

Tip/Tilt Adjusters


Lifting TalonLifting Talon Interface to Moving Frame:– Moving Frame captured by Talon:

Fail safe, MSA cannot fall off crane - Interlocked

– Self-aligning, kinematic joint – Cylinder in V-groove

Plastic Entrance PieceProtects mirror if accidental

contact occurs

Lifting TalonSegment Removal Sequence– Segment lifted to full stroke: 300mm

– Talon lowered (Claws open)stop at 5-15 mm below capture height

– Talon closedInterlocks verified

– Check Talon closed?– Check moving frame tang inserted in socket?

– Jack begins to lowerTalon Load Cell monitors handoff

Expect TBD weight on Talon after TBD Jack Motion

– TBDs Depend on Crane stiffness

Jack stops after retracting 40mm

– With handoff verifiedSegment extracted

Crane Departs

– Jack re-positioned to receive new MSA

– Crane lowers Talon & Segment toward array

– Moving frame engages onto Jack Center Shaft

– Crane stops at segment height 275-285mm

– Jack extended until MF liftoff detectedIndicator lights on Talon verify handoff

– Talon opens

– Crane departs

– Jack lower segment into position.
