Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural scheme of mechanism of the present invention.
In figure: 1, electric motor end cap, 2, brake disc, 3, armature, 4, magnetic yoke body, 5, " L " shape release board, 6, manual release handle, 7, tractive magnet, 8, release screw.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, the powerless magnetic brake of the braking of a kind of energy power release and electronic recovery braking, comprise the magnetic yoke body 4 be arranged on main shaft, armature 3 is provided with on the right side of magnetic yoke body 4, Compress Spring is provided with between magnetic yoke body 4 and armature 3, magnetic yoke body 4 is provided with pin-and-hole above, brake disc 2 is provided with on the right side of armature 3, electric motor end cap 1 is provided with on the right side of brake disc 2, magnetic yoke body 4 inside is provided with release screw 8, one end of release screw 8 is connected on " L " shape release board 5, the other end is connected with armature 3, the quantity of release screw 8 is two, two release screw 8 are symmetrical arranged centered by main shaft, the side of " L " shape release board 5 is provided with manual release handle 6, tractive magnet 7 is arranged on the side of manual release handle 6 and enters in the pin-and-hole above magnetic yoke body 4 through " L " shape release board 5.
The technological scheme that the present invention optimizes further, establishes at regular intervals between the side of described " L " shape release board 5 and magnetic yoke body 4.
The technological scheme that the present invention optimizes further, described magnetic yoke body 4 is fixedly connected on electric motor end cap 1 by mounting screw.
The technological scheme that the present invention optimizes further, is provided with damping device in the gap between described mounting screw and armature 3.
The technological scheme that the present invention optimizes further, is provided with bump protection ring in the gap between described armature 3 and mounting screw.
The working procedure of Electronic control brake off state: be first energized to electromagnetic power-off brake, now yoke 4 adhesive armature 3 brake off, connect the coil power of tractive magnet 7 at once, the pin rod of tractive magnet 7 is under the effect of electromagnetic force, be pushed in the pin-and-hole on yoke 4 cylindrical, then the power supply of first breakaway braking device, after break deenergization, magnetic flux disappears, armature 3 pushes brake disc 2 under the effect of Compress Spring, simultaneously by two release screw 8 on armature 3, manual release handle 6 is pulled to move right, because the push rod of tractive magnet 7 is also in the pin-and-hole of yoke, continue to move to brake disc 2 direction because which limit armature, armature 3 and the brake disc 2 of break are in separated state, disconnect the power supply of tractive magnet 7 more at once, the pin rod of tractive magnet 7 has just been stayed in the pin-and-hole of magnetic yoke body 4, now electromagnetic power-off brake is in the releasing state of brake off, reach Electronic control brake off and the requirement of state can also be maintained.
Electronic control recovers the working procedure of braking state: be energized to electromagnetic power-off brake, yoke 4 produces electromagnet pull adhesive armature 3, relieve the pressure be applied on brake disc 2, release board 5 is in loosening state, now the depression bar of electromagnet is extracted under the effect of Returnning spring in the pin-and-hole of yoke 4, give electromagnetic power-off brake power-off again, electromagnetic power-off brake is now just in dead electricity braking state, reaches the object that Electronic control removes non-brake state.
Present invention preserves the function of manual release, manually and electric dual-purpose, can realize braking and non-brake state, inconvenience, operating space are narrow and small up and down to solve high-lift operation, and the operational issue in place that personnel not easily arrive, practical, operation is more convenient.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
