Description
Technical field
The utility model relates to automated execution member arts, particularly relates to a kind of remote electric release electromagnetic power-off brake.
Background technique
Electromagnetic brake is a kind of connector master end torsion being conveyed to passive side, can combine freely according to needs, cut off or brake, start is carried out because using electromagnetic force, be referred to as magnetic clutch, break, electromagnetic brake is a kind of desirable automated execution element in modern industry, in machine driven system, mainly play the effect such as transferring power and controlled motion.Have compact structure, simple to operate, respond sensitive, the life-span is permanent, uses reliable, is easy to realize the advantages such as distant control.
Traditional electromagnetism dead electricity braking, primarily of compositions such as yoke, armature, brake disc (rotor), geared sleeves, under normal circumstances, during yoke dead electricity, is in braking state.Under some specific environment, namely dead electricity brakes is not often best state.Tower crane such as on building site, if the balance arm of tower crane is braked when dead electricity, when the horizontal wind-engaging of balance arm, because blowing area is larger, the Amplitude Ratio that tower crane can be made to wave is comparatively large, and in this case, traditional electromagnetism dead electricity braking just exists certain defect.If one can be designed, telecontrol whether can brake as required during dead electricity, can address this problem.
Model utility content
The purpose of this utility model is to provide a kind of remote electric to discharge electromagnetic power-off brake, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of remote electric release electromagnetic power-off brake, comprise the yoke be arranged on main shaft, be arranged on armature on the right side of yoke, between yoke and armature, brake spring is set, it is characterized in that: on the right side of described armature, brake disc is installed, described yoke inside is through link screw rod, link screw rod one end is connected with armature, the other end connects the connecting plate be arranged on the left of yoke, connecting plate lower end is shaped with the boss stretched out to the right, moveable electromagnet is provided with above described connecting plate, electromagnet lower end is provided with push rod, and described electromagnet also connects Returnning spring.
Described link screw rod arranges two altogether, and two link screw rods are symmetrical arranged centered by main shaft, and two link screw rod in the vertical directions are arranged on the middle part of connecting plate.
As needed release, by brake guaranties, armature drives connecting plate to move to the left by link screw rod, connecting plate upper end is separated with yoke, now be energized to electromagnet, under magnetic force, electromagnet moves downward, the push rod of electromagnet lower end inserts in the gap of yoke and connecting plate, again by break power-off, connecting plate reset under the effect of brake spring (moving to the right) push down the push rod of electromagnet, the armature of break can not thoroughly be resetted, still releasing state are in after break dead electricity, finally by electromagnet power-off (now break, the equal no electric circuit of electromagnet).
As electronic release (acquisition braking state) need be removed, only break need be energized instantaneously.Break is energized instantaneously, and now armature drives connecting plate to move to the left, and electromagnet automatically resets under the effect of Returnning spring, and the push rod of electromagnet is extracted from gap, and break normally can discharge or brake (the same with common break).
The beneficial effects of the utility model are:
The utility model provides a kind of remote electric to discharge electromagnetic power-off brake, and dead electricity can be selected as required to brake for this break or dead electricity is not braked, and by magnet control, can realize remote electric release; The function of conventional brake can be had, dead electricity can be switched again as required and whether be in releasing state.
Accompanying drawing explanation
Fig. 1 is front sectional view of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in mode of execution, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
As Fig. 1, shown in Fig. 2, a kind of remote electric release electromagnetic power-off brake, this break is for tower crane, comprise the yoke 4 be arranged on main shaft 8, be arranged on the armature 5 on the right side of yoke 4, brake spring 6 is set between yoke 4 and armature 5, brake disc 7 is installed on the right side of armature 5, yoke 4 inside is through link screw rod 1, link screw rod 1 one end is connected with armature 5, the other end connects the connecting plate 2 be arranged on the left of yoke 4, connecting plate 2 lower end is shaped with the boss 9 stretched out to the right, moveable electromagnet 3 is provided with above connecting plate 2, electromagnet 3 lower end is provided with push rod 10, electromagnet 3 also connects Returnning spring 11.During normal power-up work, break is in releasing state, armature 5 is attracted by yoke 4, brake spring 6 is compressed by armature 5, under the drive of link screw rod 1, move to the left in the upper end of connecting plate 2, and there is gap between yoke 4, if now want break dead electricity not brake, just electromagnet 3 is energized, under magnetic force, electromagnet 3 moves down, push rod 10 inserts in the gap between connecting plate upper end and yoke 4, again by yoke 4 power-off of break, under brake spring 6 acts on, armature 5 moves right, armature 5 pulls connecting plate 2 to the right by link screw rod 1, connecting plate 2 upper end compresses push rod 10, under the stop of push rod 10, armature 5 can not reset to the right completely, break is still in releasing state.Although now break power-off, the balance arm of tower crane still can freely rotate, if there is wind, balance arm under wind-force effect, can rotate to parallel with wind direction, thus reduces blowing area, and tower crane significantly can not be waved in wind.To remove dead electricity release, break dead electricity braking state namely to be obtained, as long as break is energized instantaneously.Break is energized instantaneously, and now armature drives connecting plate to move to the left, and electromagnet automatically resets under the effect of Returnning spring, and the push rod of electromagnet is extracted from gap, and break can normally discharge or brake.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification is only preference of the present utility model; be not used for limiting the utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
