The specific embodiment
Below, utilize accompanying drawing that embodiment is described.Fig. 4 represents the planar view of the present embodiment corresponding with the Fig. 3 that has brake equipment now.In addition, Fig. 5 represents the cross-sectional configuration figure of the brake equipment corresponding with Fig. 2.
In the figure, symbol 32,31b, 32c, 32d, 34c, 34d, 36c, 36d are corresponding with symbol 12,22b, 22b, 24c, 24d, 26c, 26d among Fig. 1 and Fig. 2.
In example shown in Figure 4, on the existing position of friction ring 31b, be provided with 4 electromagnetism Compress Spring 34c that are pressed against on the slipper 32c.
Other structures are identical with Fig. 2.That is, this brake equipment has: the dish 31, connect antermarginal part around, have the friction ring 31a, the 31b that are arranged on both sides; Slipper 32c, 32d are pressed against on this dish 31; Check plate 35c, 35d; And hold-down bolt 36c, 36d, fix these slippers, check plate and dish.The plane of revolution moving contact of friction ring 31a and rotation drive motor 11.
In the inside of check plate 35c, on the position on the circular arc that makes progress as shown in Figure 4, have 4 electromagnetism Compress Spring 34c, in check plate 35c, also have the magnet coil 33c that these electromagnetism Compress Springs 34c is switched on and controls.In the inside of check plate 35d, on the position on the downward as shown in Figure 4 circular arc, have 4 electromagnetism Compress Spring 34d, in check plate 35d, also have the magnet coil 33d that these electromagnetism Compress Springs 34d is switched on and controls.The intensity of 8 electromagnetism Compress Spring 34c, 34d is roughly the same.At magnet coil 33c, when 33d does not switch on, electromagnetism Compress Spring 34c, 34d are pressed into slipper 32c, 32d on the dish 31 from its back side by its original power.
Hold-down bolt 36c and slipper 32c and check plate 35c are arranged on four jiaos accordingly, and hold-down bolt 36d and slipper 32d and check plate 35d are arranged on four jiaos accordingly.
Utilize Fig. 4 and Fig. 5 that the action of present embodiment is described.When magnet coil 33c, 33d were switched on, electromagnetism Compress Spring 34c, 34d were by the direction compression to arrow 37c, 37d, and the pressing force that is applied on the dish 31 reduces, and reduced rotation drive motor 11 rotations from coiling 31 pressing forces to rotation drive motor 11.When disappearing to the energising of magnet coil 33c, 33d, electromagnetism Compress Spring 34c, 34d extend naturally, and slipper 32c, 32d increase coiling 31 pressing force.This braking is for example with inversely proportional to the electric current of magnet coil 33c, 33d energising.
Therefore, usually, by never the state of magnet coil 33c, 33d energising being begun to switch on gradually and electric current is increased the rotation of the rope 13 of suspention lift car is accelerated, improve thus the rising or falling speed of lift car, when near bed of interest, again make to the electrical current of magnet coil 33c, 33d to reduce and apply braking, and at bed of interest electrical current stopped, and with slipper 32c, 32d by being pressed on the dish 31.
So, can make to the electrical current of magnet coil 33c, 33d and change and the rising or falling speed of control lift car, stop.
In addition, also can for, making when increasing gradually to the electrical current of magnet coil 33c, 33d, electromagnetism Compress Spring 34c, 34d are increased gradually to the pressing force of slipper 32c, 32d.
According to present embodiment, on electromagnetism Compress Spring 34c, 34d the is arranged on position corresponding with the friction ring 31b that coils 31, therefore change by the electrical current that makes magnet coil 33c, 33d, can easily carry out the braking of drg.
Yet, in the above-described embodiment, the brake equipment that is provided with 8 electromagnetism Compress Springs with roughly the same pressing force is illustrated.But these springs also can not have the pressing force of same degree.
Fig. 6 represents the figure corresponding with Fig. 4 of this embodiment.Electromagnetism Compress Spring in this case except the electromagnetism Compress Spring 44c with common pressing force, also has electromagnetism Compress Spring 44c ', 44d ', and this electromagnetism Compress Spring 44c ', 44d ' have stronger pressing force.
In Fig. 6,41b, 42c, 42d, 46c, 46d are corresponding with 31b, 32c, 32d, 36c, 36d among Fig. 4.In example shown in Figure 6, respectively be provided with respectively 2, be provided with 4 electromagnetism Compress Spring 44c, 44c ' that are pressed against on the slipper 42c altogether.In example shown in Figure 6, be provided with 4 electromagnetism Compress Spring 44d, 44d ' that are pressed against on the slipper 42d.Other are identical with structure shown in Figure 5.
In above-mentioned embodiment shown in Figure 6, the intensity of electromagnetism Compress Spring is two kinds, but also can be for more than three kinds.In addition, need to not be arranged side by side two springs that elastic force is stronger in central authorities, spring that also can elastic force is stronger and weak spring alternately arrange.
According to present embodiment, on electromagnetism Compress Spring 44c, 44c ', 44d, 44d ' the is arranged on position corresponding with the friction ring 41b that coils, therefore by changing the electrical current of magnet coil, can easily carry out the braking of drg.In addition, because the intensity of electromagnetism Compress Spring is different, therefore exist than the easier advantage of carrying out the braking of drg of embodiment shown in Figure 4.
According to above-described at least one embodiment, can access the brake device for elevator that carries out easily the actv. braking and can not produce noise.
Several embodiments of the present utility model are illustrated, but these embodiments point out as an example, be not intended to limit the scope of utility model.These new embodiments can be implemented with other variety of ways, in the scope that does not break away from the utility model purport, can carry out various omissions, displacement and change.These embodiments with and distortion be included in the scope and purport of utility model, and be included in the utility model that patent request scope puts down in writing and in the scope that is equal to it.
