Detailed description of the invention
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, including electric magnet 1, brake arm 2, braked wheel 3, female iron core 51, rail-road core 52 and housing 14, it is internal that electric magnet 1, female iron core 51 and rail-road core 52 are arranged at housing 14, female iron core 51 and rail-road core 52 one end are hinged by the top of connecting rod 15 with brake arm 2 after stretching out housing 14 respectively, the cantilever 4 of "eight" shape it is provided with bottom housing 14, the intermediate ends of brake arm 2 and cantilever 4 one end are hinged, and the bottom of two brake arms 2 is connected by screw rod 6, nut 10；It is provided with tripping spring 92 between this nut 10 and bottom of brake arm 2；
Two brake arms 2 surround a cavity matched with braked wheel 3 phase, and the inwall of two brake arms 2 is all symmetrically arranged with braking tile fragment 12, and braking tile fragment 12 outer surface is fixedly installed braking block rubber 11, and braking tile fragment 12 is connected with brake arm 2 by air bag 13.
Further, described screw rod 6 is also threaded two hand nuts 7, and two hand nuts 7 are respectively positioned between two brake arms 2；One hand nut 7 is positioned at the inner side of left end brake arm 2, and another hand nut 7 is positioned at the inner side of right-hand member brake arm 2.When two hand nuts 7 are toward when screw rod 6 is middle or both sides rotate, it is possible to achieve manual degree of tightness braked wheel 3.
Further, described brake arm 2 is provided with several counterbores 2-1, counterbore 2-1 gap and is nested with damping spring 91, and braking tile fragment 12 inwall is connected to bolt 8, threadeds with nut 10 phase after sequentially passing through air bag 13, damping spring 91, counterbore 2-1 in bolt 8 one end.So can reduce the braking tile fragment 12 impulsive force to braked wheel 3, effectively extend the service life of braked wheel 3.
Further, described female iron core 51 one end is circumferentially provided with several shrinkage pools 51-1, and rail-road core 52 one end is circumferentially provided with several projection 52-1 matched with shrinkage pool 51-1 phase, and projection 52-1 outer wall is enclosed with EVA cotton layer；EVA cotton layer can play the effect such as noise reduction, buffering.
The operation principle of the present invention: when elevator remains static, in the coil of the electromagnetic brake of hoisting motor, no current passes through, at this moment because there is no captivation between female iron core 51 of Breake Electromagnet 1 and rail-road core 52, braking tile fragment 12 is under the pressure effect of tripping spring 92, braked wheel 3 is held tightly, it is ensured that elevator is in idle resting state；When the moment that hoisting motor energising rotates, coil in Breake Electromagnet 1 is also electrified stream simultaneously, while electric magnet 1 magnetizes rapidly and makes female iron core 51 and rail-road core 52 adhesive, brake arm 2 is driven to overcome the active force of tripping spring 92, braking tile fragment 12 is made to open, completely disengage from braked wheel 3, so that elevator is run when brakeless power；When lift car arrives required landing stop, hoisting motor dead electricity, coil in Breake Electromagnet 1 also simultaneously dead electricity, magnetic force in electric magnet 1 rapidly disappears, female iron core 51 and rail-road core 52 are resetted by brake arm 2 under the effect of tripping spring 92, make braking tile fragment 12 again be embraced by braked wheel 3, then elevator stops.
When using the present invention, by the damping of air bag, damping spring, greatly reducing impulsive force in braking procedure, its stable performance, noise is little, and braking is reliable, and is conducive to extending the service life of traction machine.It addition, this simple in construction, reasonable in design, low cost of manufacture.
The above is only the better embodiment of the present invention, therefore all equivalences done according to the structure described in present patent application scope, feature and principle change or modify, and are all included within the scope of present patent application.
