Fig. 1 is the utility model structural representation.

Fig. 2 is Figure 1A-A schematic representation.

Fig. 3 is the utility model electrical schematic diagram.

Below in conjunction with accompanying drawing the utility model is further described:

Mounting 6 is made by two corresponding iron plates, and an end is respectively equipped with axle sleeve 25,30 and magnetic shield 24,29 and stops a grade 4(and be made up of reed) constitute.The other end of mounting 6 is integral admittedly by the static iron core 9 of screw 22 with the bipolar electromagnetic mechanism made from permeability magnetic material.Coil 8 is housed in the circular trough of static iron core 9, and it is coil 8 is fixing with compensated loop 10, compensated loop 10 strengthens the effect of magnetic pole area in addition except that fixed coil 8, static iron core 9 opposite sides are provided with the yoke 16 of force pushing type electromagnetic mechanism, place coil 15 in its groove, place armature 17 in coil 15 holes, place stage clip 19 in the groove of armature 17, in its hole and be fixed with not magnetic conduction pin rod 18, iron core 13 usefulness screws 14 are fixing with yoke 16, be placed with stage clip 19 and magnetic conduction pin rod 20 in the groove of iron core 13 too, magnetic conduction pin rod 20 slides in the groove of iron core 13, and both are integral admittedly with pin with magnetic conduction pin rod not 18.

Movable arm 7 is also made by two iron plates of correspondence, which is provided with axle sleeve 26, magnetic shield 27 and jacking block 5, and is integral admittedly by screw 12 and movable core 11.Movable arm 7 is by rotating shaft 2, packing ring 3, and magnetic isolating pad 28, magnetic shield 27, axle sleeve 26 is assembled into this drive unit with mounting 6.The movable core 11 that is contained in static iron core 9 chambeies can move up and down nimbly and freely by rotating shaft 2, movable arm 7, and its movement travel is limited by the square hole 23 that stops shelves 4 and be located on the movable arm 7. Magnetic shield 24,27,29 and magnetic isolating pad 28 are housed on the static iron core 9, can realize every magnetic.

Working procedure:

Electronic switch 21 is contained in static iron core 9 one sides.Give electronic switch 21 when feed, pass through V ₈Respectively to R ₁, C ₁And R ₂, C ₂Charging, and pass through V ₆Realization is to coil 15(M ₂) excitatory, C at first ₁Current potential rise rapidly, make V ₃So conducting is V ₂Conducting is to coil 8(M ₁) excitatory, the bipolar generation suction of static iron core 9 makes movable core 11 adhesives, so movable arm 72 rotations around the shaft move down, by jacking block 5, compressing brake rod 1 is realized declutching.Because coil 15(M ₂) by excitatory, moved so armature 17 inhales, the magnetic conduction pin rod 20 stressed locking positions that are displaced to pin the locking of realization mechanisms with movable arm 7.Because coil 15(M ₂) be in "on" position, so brake bracket keeps declutching.In addition after brake bracket has been finished the task of declutching, C ₂Current potential rise to specified value, V ₅, V ₄Conducting makes V ₃, V ₂(unidirectional silicon cell) ends, coil 8(M ₁) loss of excitation, bipolar electromagnetic mechanism is in electroless state, and braking keeps declutching operation.When disconnecting the power supply of electronic switch 21, coil 15(M ₂) loss of excitation, armature 17 moves on to assigned position after under the effect of stage clip 19, and magnetic conduction pin rod 20 breaks away from locking position, and movable arm 7 is returned to and stops on shelves 4 positions that limited under the effect of brake bracket spring, and brake bracket closes lock.

The utility model has following advantage compared to existing technology:

1, nominal torque doubles than prior art;

2, allow the pass to close number of times and improved 4～40 times, so the life-span is long than prior art;

3, holding current has reduced by 3～5 times than prior art, so economize on electricity;

4, material can be little with plain carbon steel and the little boundary dimension of volume, so joint iron joint copper cost is low;

5, safe and reliable, power supply disconnects and can reliably throw off, and realizes safety brake;

6, installation dimension and existing product are equal to and are convenient to the user and replace.
