Description
Technical field
The present invention relates to a kind of level type steel plate structure, more particularly to a kind of steel plate structure used in electricity loss brake.
Background technology
At present, the friction brakes of dead electricity braking are generally used in lifting means, this brake can be realized putting down
Steady to stop and quick start and safety arrestment when power is off, main Types have：It is double to push away brake, axle brake, disc type brake
Device, block brake are also referred to as：Board-like brake etc., wherein using it is most wide be block brake, it is suffered on brake axle to make
The counteracted by pressure of brake block, generally uses in pairs and is arranged at motor both sides.
The friction brakes of existing dead electricity braking, typically using induction coil, by the break-make of control coil electric current,
The adhesive or release of quiet plate and dynamic plate are realized, and then realizes the effect of dead electricity braking.As traditional structure is limited, general coil
The active force of generation is identical with the brake force of brake, to improve brake braking force, just must be to the overall structure of brake
Make improvements with coil.
The content of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of small volume, the cost of material is low, and in phase
The lever shape steel plate of brake braking force is effectively improved in the case of with coil.
In order to realize above-mentioned purpose, following technical scheme is present invention employs：
A kind of lever shape steel plate, including the first plate and the second plate, one end of first plate are provided with breach, and lack
The first sleeve is equipped with the middle part of the lath of mouth both sides；One end of second plate is stretched in breach, and termination and indentations bottom
Space is left, second plate is stretched into, first sleeve and second sleeve
Run through in same straight line, and the first sleeve and second sleeve and be provided with bearing pin.
Preferably：Distance and first bushing core to first of first bushing core to the first plate outer end
The ratio of the inner distance of plate is more than 4, distance and the second sleeve center at the second sleeve center to the second plate outer end
Ratio to the inner distance of the second plate is also greater than 4.
Compared with prior art, the invention has the beneficial effects as follows：It is as the present invention adopts lever construction, former according to lever
Reason, under identical braking radius parameter, the comparable conventional brake of induction coil the suction-combining force reduces 75%；And identical coil, adopt
Brake force 300% can be increased with this lever-type brake；As two blocks of steel plates are also passed through hinge together by the present invention,
Therefore the small volume of the present invention, and then in the case of identical braking radius with the output of identical brake force, material cost 50% can be reduced
More than.
Description of the drawings
Fig. 1 is the cross-sectional view of the brake using the present invention.
Fig. 2 is the dimensional structure diagram of the brake using the present invention.
Fig. 3 is the dimensional structure diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is made a detailed explanation.
A kind of twin coil level type block brake as shown in Figure 1 and Figure 2, including brake main body 1, dynamic plate 4 and friction
Piece 5, the friction plate 5 are fixed on the lower surface of dynamic plate 4, and the middle part upper surface of the brake main body 1 is provided with the first projection 12,
Downward opening recess is provided with the middle part of first projection 12, the top of first projection 12 is also fixed with by the first bolt
Pressing plate 9；The bottom of the brake main body 1 is quiet plate 11, and the two ends of the quiet plate 11 are provided with groove, are fixed with the groove
Induction coil 6；Induction coil is arranged on quiet plate two ends, makes full use of quiet board space, obtains maximum braking force with minimum steel.
Lever steel plate 2 is provided with above the quiet plate 11, as shown in figure 3, the lever steel plate 2 includes the first plate 21 and
Two plates 24, one end of first plate 21 are provided with the middle part of breach 23, and the lath of 23 both sides of breach and are equipped with the first sleeve
22；One end of second plate 24 is stretched in breach 23, and space, second plate 24 are left with 23 bottom of breach in termination
Stretch into and in the middle part of 23 part of breach, be additionally provided with second sleeve 25, first sleeve 22 and second sleeve 25 are in same straight line,
And lever steel plate 2 is hinged on into brake main body 1 through the first sleeve 22, second sleeve 25 and recess sidewall by bearing pin 3
In recess sidewall；The outer end of first plate 21 and the second plate 24 respectively positioned at the top of two induction coils 6, described the
The inner of one plate 21 and the second plate 24 is respectively positioned on below pressing plate 9, the pressing plate 9 and the first plate 21 and the second plate 24
Hold down gag is equipped between inner upper surface；The dynamic plate 4 is connected with the lower section of quiet plate 15 by the second bolt 42, and second
Dynamic plate early warning spring 43 is additionally provided between bolt 42 and dynamic plate 4, dynamic plate can quickly be declutched by dynamic plate preloading spring 43 when being powered,
Avoid the abrasion that friction plate is unnecessary；The middle part of the dynamic plate 4 is provided with upwardly extending second projection 41, second projection 41
Upper end the lower surface in the middle part of lever steel plate 3 is against after the quiet plate 15.
First sleeve, 22 center to 21 outer end of the first plate distance and 22 center of the first sleeve to the first plate 21
The ratio of inner distance is more than 4, in the distance and second sleeve 25 at 25 center of the second sleeve to 24 outer end of the second plate
The heart to the distance of 24 the inner of the second plate ratio also greater than 4.
Gap is provided between the pressing plate 9 and raised line 12, and the bottom of pressing plate 9 is provided with multiple holding tanks.It is described to compress dress
Put including compressing lead column 7 and being set in the holddown spring 8 compressed in lead column 7, described one end for compressing lead column 7 is provided with
Convex surface, one end and the convex surface of holddown spring 8 offset, and the other end is offseted with 9 lower surface of pressing plate, under the active force of holddown spring 8
Compressing lead column 7 has one end of convex surface and the inner upper surface of the first plate 21 or the second plate 24 to offset, and the other end stretches into pressure
In the corresponding holding tank of plate 9.
When the present invention is in "on" position, as coil produces magnetic field, lever steel plate long-armed one end is inhaled, shortwall one
End upwarps and causes holddown spring stress, moves plate and fits with quiet plate in the presence of dynamic plate early warning spring, i.e. friction plate is away from stopping
Wheel, it is long-armed much larger than galianconism due to lever steel plate, so utilizing lever principle, it is possible to achieve complete electricity with less suction
The action that magnetic declutches.When motor power-off, the magnetic field halts that coil is produced, lever steel plate are acted in the elastic force of holddown spring
Under, long arm end is upwarped, and galianconism end pushes, the wall upper end of galianconism side pressure plate forced to move so that dynamic plate overcomes dynamic plate early warning spring
Active force, the friction plate compression brake wheel most moved at last on plate are braked.
