The working principle of the utility model is: after the utility model installs, when crane prepares in assigned work position
After ready, corresponding position on the ground is needed to fix iron plate to replace sleeper, and frog type supporting leg assembly 9 is placed at this
On a little iron plates, start crane, crane can start to work, at this time nominal situation of the four of the crane supporting leg in crane
Lower and ground fits closely and is under the monitoring of magnetic force guard system.
If certain moment, crane because overload or the problems such as misoperation will occur or have already appeared to topple
When dangerous, when some permanent magnetism ballistic support floor pan assembly 6 on crane frog type supporting leg assembly 9 will leave iron plate, crane
Pressure sensor 15 on support baseboard outer housing 10 detects the rapid pressure drop on crane support baseboard outer housing 10
And it is lower than some critical value, sensor circuit is connected under the action of pressure sensor 15 at this time, on the one hand starts alarm system hair
Alarm out, instruction crane operator stop constructing immediately and take corresponding measure；On the other hand, starting magnetic force protection system
System, servo motor 20 starts to work and drives moving magnet shaft 14 by synchronous belt 19, then passes through thrust disc 21 and thrust link
22 linkage, and all moving magnet shafts 14 is finally made to rotate predetermined angular, to drive moving magnet 17 to turn over 180 degree, at this time
The pole N of moving magnet 17 and the pole N of fixed magnet 18 be located at it is ipsilateral, the pole S be similarly positioned in it is ipsilateral, as shown in figs. 7-8,17 He of moving magnet
The magnetic direction of fixed magnet 18 is identical, and the magnetic line of force that moving magnet 17 and fixed magnet 18 generate passes through respectively from the respective pole N
The iron plate fixed on the ground returns to the respective pole S, i.e., generates powerful suction to iron plate, make permanent magnetism ballistic support floor pan assembly 6
It is fitted tightly on iron plate, maintains the balance of crane.
Corresponding measure is being taken, such as after stopping working immediately and unloading weight, crane is under the operating condition of safety, behaviour
Author can press control switch, and alarm system is no longer alarmed.At this point, servo motor 20, which receives, releases magnetic force guard signal and anti-
To predetermined angular is turned to, moving magnet 17 is driven to reversely rotate 180 degree and reset, at this time the pole N of moving magnet 17 and fixed magnet 18
The pole N it is not ipsilateral, S is not extremely equally ipsilateral.Later, the magnetic line of force of moving magnet 17 and fixed magnet 18 not yet reach iron plate it
It is preceding just to form closed circuit in inside and cancel out each other, as shown in Figure 6, the magnetic line of force side of moving magnet 17 and fixed magnet 18
To on the contrary, the magnetic line of force can offset each other for one group of moving magnet 17 and fixed magnet 18, and suction cannot be generated to iron plate,
The magnetic force of 6 pairs of permanent magnetism ballistic support floor pan assembly fixed iron plates disappears, whole system whole return, and waiting acts on next time.
