The operating instruction of this slewing:
1, levelling and locking function
When equipment walking is entered the station before platform, the state for rotating cockpit is uncertain, thus need will after rotation cockpit levelling again into
It stands.At this point, the trigger mechanism on adjustment section rail will touch the clutch in equipment, driving handle is rotated after being touched
Drive master arm rotation, movable stand pushed so that motor and active magnetic clutch turntable 7 with movable stand to the right with respect to chassis
Top is mobile, and active magnetic clutch turntable 7 is pulled to driven magnetic turntable 3 close to aligned position, such as Fig. 6, at this point, driven
Disk and the lower disk spacing of active magnetic clutch turntable 7 only have 1mm in magnetic rotary disk 3, and the magnet between them will be mutually attracting
Draw and the two is aligned to the state attracting to each pair of magnet NS, when rotating cockpit or motor attempts rotation, will make disc-shaped up and down
It misplaces at low-angle, the suction between magnet will prevent the torque that disk misplaces up and down in tangential generate at this time, when this torque foot
When enough big, we can be used to reach the locked purpose of upper and lower disk, realize and rotate synchronously.Disk is equivalent to one up and down at this time
The function of a magnet clutch links motor and pivoting support, thus linkage rotation cockpit and motor.So this when of motor
Starting will drive rotation cockpit rotation, be alignment function；When motor is locked, upper frame will also be locked, and be locking function.
2, non-contact type magnetic speed limiting function:
When car body art skating in orbit, chassis along on track when art skating, rotation cockpit with respect to chassis by
It is rotated freely for 360 ° in inertia meeting, however, to ensure that the comfort of passenger, will control the maximum speed of rotation, it is to use in the past
Purely mechanical brake carries out speed limit, there are problems that maintenance and abrasion.And the present apparatus is a kind of contactless damping mechanism, when
When car body is free to slide, disk is in disengaged condition.Due to rotating the linkage of cockpit and shaft gear 10, rotation cockpit be will drive
Upper disc rotation, but annular damper plate 9 is motionless, and two groups of magnet of upper disk form vertical side in the space of annular damper plate 9
The upward magnetic line of force, when upper disk and annular damper 9 relative rotation of plate, annular damper plate 9 does cutting magnetic force in this magnetic field
Line moves, and vortex is generated in annular damper plate 9, due to electromagnetic induction principle, will generate between annular damper plate 9 and upper disk
One electromagnetic damping torque, to prevent the relative rotation of annular damper plate 9 and upper disk, and relative rotation speed is bigger, and damping turns
Square is bigger.The above is the case where disk disengages, actually since dampened disk is always in the magnetic field of upper disk, any time magnetic resistance
Buddhist nun is existing.
