The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the block type electromagnetic brake of a kind of elevator of the present invention, comprise electromagnet 1, brake control lever 2, brake wheel 3, female iron core 51, male iron core 52 and housing 14, electromagnet 1, female iron core 51 and male iron core 52 are all arranged on housing 14 inside, female iron core 51 and male iron core 52 one end are hinged by connecting rod 15 and the top of brake control lever 2 after stretching out respectively housing 14, housing 14 bottoms are provided with the cantilever 4 of "eight" shape, the intermediate ends of brake control lever 2 and cantilever 4 one end are hinged, and the bottom of two brake control levers 2 is connected by screw rod 6, nut 10; Between this nut 10 and the bottom of brake control lever 2, be provided with retarding spring 92;
Two brake control levers 2 surround a cavity matching mutually with brake wheel 3, and the inwall of two brake control levers 2 is all symmetrically arranged with braking tile fragment 12, and braking tile fragment 12 outside faces are fixedly installed braking rubber block 11, and braking tile fragment 12 is connected with brake control lever 2 by air bag 13.
Further, described screw rod 6 has also been threaded 7, two hand nuts 7 of two hand nuts all between two brake control levers 2; A hand nut 7 is positioned at the inner side of left end brake control lever 2, and another hand nut 7 is positioned at the inner side of right-hand member brake control lever 2.When two hand nuts 7 are in the middle of screw rod 6 or when both sides rotate, can realize manual degree of tightness brake wheel 3.
Further, described brake control lever 2 is provided with several counterbores 2-1, counterbore 2-1 gap is nested with damping spring 91, and braking tile fragment 12 inwalls are connected with bolt 8, and bolt 8 one end are successively through being threaded mutually with nut 10 after air bag 13, damping spring 91, counterbore 2-1.Can reduce to brake like this impulsive force of 12 pairs of brake wheels 3 of tile fragment, effectively extend the service life of brake wheel 3.
Further, described female iron core 51 one end are circumference and are provided with several shrinkage pools 51-1, and public iron core 52 one end are circumference and are provided with several and the projection 52-1 that shrinkage pool 51-1 matches mutually, and projection 52-1 outer wall is enclosed with the cotton layer of EVA; The cotton layer of EVA can play the effects such as noise reduction, buffering.
Principle of work of the present invention: when elevator remains static, in the coil of the magnet stopper of hoisting motor, no current passes through, at this moment because there is no attractive force between female iron core 51 of brake electromagnet 1 and male iron core 52, braking tile fragment 12 is under the pressure-acting of retarding spring 92, brake wheel 3 is held tightly, guaranteed that elevator is in out-of-run quiescence; When the moment of hoisting motor energising rotation, coil in brake electromagnet 1 is also electrified stream simultaneously, electromagnet 1 magnetizes rapidly when making female iron core 51 and male iron core 52 adhesive, drive brake control lever 2 to overcome the application force of retarding spring 92, making to brake tile fragment 12 opens, depart from completely with brake wheel 3, thereby elevator is moved the in the situation that of brakeless power; When the required landing stop of elevator car arrives, hoisting motor dead electricity, coil in brake electromagnet 1 is while dead electricity also, magnetic force in electromagnet 1 rapidly disappears, female iron core 51 and male iron core 52 reset by brake control lever 2 under the effect of retarding spring 92, make to brake tile fragment 12 and again brake wheel 3 is embraced, elevator stops.
When use is of the present invention, by the damping of air bag, damping spring, greatly reduce impulsive force in braking procedure, its stable performance, noise is little, and braking is reliable, and is conducive to extend the service life of towing machine.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
