One end is flexibly connected with the movable stand, and the master pendulum arm 811 forms parallelogram from swing arm 821, movable stand and chassis
Connection structure, is fixed with driving handle 83 on the lateral main shaft 81, and the middle part of driving handle 83 turns with the laterally master
Axis 81 connects, and one end of the driving handle 83 is after being triggered so that driving handle drives freely touching for lateral main shaft rotation
Originator 831, gas spring 84 is connected between 83 other end of the driving handle and chassis.
In order to keep movable stand run steady and whole device performance stablize, it is described transverse direction main shaft with laterally from
Shaft is arranged in sustained height.
It is equipped with to generate when driven magnetic turntable 3 rotates between the chassis 1 and driven magnetic turntable 3 and driven magnetic is turned
The non-contact magnetic damping unit of 3 damping force of disk.
The non-contact magnetic damping unit includes the annular damper plate 9 being fixed on chassis and is arranged in the driven magnetic
Property turntable 3 on several spaced annular partitions 311 up and down, be equipped between adjacent annular partition board 311 and hindered for the annular
The annular groove that Buddhist nun's plate 9 stretches into, is equipped with first permanent magnet 31 on annular partition 311, several annular partitions 311 first forever
31 upper and lower directions of magnet, which forms magnetic induction line, which gangs up into complete loops, makes 3 inside of driven magnetic turntable form constant magnetic field, described

The damping force of 9 rotations.
It is heteropolar opposite between the magnetic pole levels of the first permanent magnet on driven magnetic turntable 3, first permanent magnet
Magnetic pole it is heteropolar uniformly at intervals in 3 circumferencial direction of driven magnetic turntable.The magnetic induction line of each permanent magnet is set to gang up as complete loops,
Make to form constant magnetic field inside damping unit.
The magnetic of the second permanent magnet 71 and the first permanent magnet 31 on driven magnetic turntable 3 on active magnetic clutch turntable 7
It is heteropolar opposite between the levels of pole.
The operating instruction of this slewing：
1, levelling and locking function
When equipment is walked into 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 moved, 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 magnetic
7 times disk spacing of disk and active magnetic clutch turntable only have 1mm on property turntable 3, and the magnet between them will attract each other
By the two levelling to state attracting each pair of magnet NS, when rotating cockpit or motor attempts rotation, will make up and down disk formed
Low-angle misplaces, and the suction between magnet will prevent the torque of disk dislocation up and down in tangential generation at this time, when this torque is enough
When big, we can be used for reaching 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 magnet clutch links motor and pivoting support, to linkage rotation cockpit and motor.So this when, motor opened
It is dynamic to drive rotation cockpit rotation, it is alignment function；When motor is locked, upper frame will also lock, 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 repair 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 can 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, one will be generated between annular damper plate 9 and upper disk
A electromagnetic damping torque, to prevent the relative rotation of annular damper plate 9 and upper disk, and relative rotation speed is bigger, damping torque
It 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 damping
All it is existing.
