Embodiment
Below through embodiment's form; Content to the utility model is done further explain; But the scope that should at this point not be interpreted as the said theme of the utility model only limits to following embodiment; Do not breaking away under the above-mentioned technological thought situation of the utility model, all various modifications, replacement and changes of making according to ordinary skill knowledge and customary means include in the scope of the utility model.
The principle of the utility model is that parallelogram is fused in the leverage of break; Conversion through parallel-crank mechanism; Drive unit and operating device are carried out reasonable Arrangement; Reduce installing space, even can be, can the abnormal shape that drive unit and operating device carry out tilting be arranged to meet the demands according to the concrete condition of installation position.
As depicted in figs. 1 and 2; The described a kind of tile fragment formula electromagnetic brake of the utility model; Mainly comprise steel cable assembly 1, electromagnet 2, outer hinge 3, left arm 4, short hinge 5, band andgudgeon chain 6, screw rod 7, right arm 8, briquetting 9, pull bar 10, brake shoe 11, brake shoe 12, spring 13, right brake arm 14, spring housing 15, base 16, right interlock sheet 18, Left-wing Federation's moving plate 19 and left brake arm 20; One side of base 16 is fixed with tensioning mechanism; Another side is fixed with electromagnet 2, and said electromagnet 2 is connected with left arm 4, and left arm 4 is provided with steel cable assembly 1.
Said tensioning mechanism is made up of pull bar 10, spring 13, spring housing 15, and said pull bar 10 is outside equipped with spring 13, is with spring housing 15 outside the spring 13, and spring housing 15 is fixed on the base 16;
Said brake shoe 12 is contained in the brake shoe 11, and is fixing with briquetting 9, and is hinged on respectively on left brake arm 20, the right brake arm 14;
Said left brake arm 20 is hinged on the base 16 with right brake arm 14, is fixed with Left-wing Federation's moving plate 19 and right interlock sheet 18 on left brake arm 20 and the right brake arm 14 respectively, and the centre of left brake arm 20 and right brake arm 14 links to each other with pin;
