The invention provides a brake of an integrated multi-point braking heavy-load elevator traction machine. By means of the brake, braking of a friction plate and a brake disc is sufficient and uniform, operation of an air gap adjustment-free structure is easy and convenient, no sharp noise is generated when magnet yokes and magnets are rapidly attracted, and the whole structure is effectively braked for a long time. The brake comprises two armatures, the two magnet yokes and a brake pad; the two magnet yokes are arranged on the planes of the two sides respectively, and the two magnet yokes are connected through a front upper stop strip and a front lower stop strip to form an integral structure; and the independent armatures are placed on the inner end faces of the magnet yokes, axially-through guide through holes are evenly distributed in the end faces of the armatures, positioning installation holes are correspondingly formed in the positions, corresponding to the guide through holes, of the magnet yokes, fixing guide columns are installed in the guide through holes, the length of the fixing guide columns is larger than the thickness of the corresponding armatures, and installation bolts penetrate the positioning installation holes and the fixing guide columns and then are fixedly connected to a traction machine fixing component.
本发明提供了一体化多点制动重载电梯曳引机的制动器,其使得摩擦片和刹车盘的制动充分均匀,且气隙免调结构的操作简单方便、磁轭和磁铁快速吸附时不会产生尖锐噪音,确保整个结构持久有效的制动。其包括两块衔铁、两组磁轭、刹车片;两块所述磁轭分列两侧平面布置,且两块所述磁轭之间通过前上挡条、前下挡条连接形成整体结构;每组所述磁轭的内端面放置有独立的衔铁,每块所述衔铁的端面均布有轴向贯穿的导向贯穿孔,所述磁轭对应于所述导向贯穿孔的位置对应布置有定位安装孔,所述导向贯穿孔内处安装有固定导柱,所述固定导柱的长度大于对应的衔铁的厚度,安装螺栓贯穿定位安装孔、固定导柱后固接于曳引机固定部件。
