起重机制动器在起升机构中有何作用?

来源:http://impnow.com/news/103.html添加时间:2015-08-12

    其葫芦式起重机的起升机构,通常是由电动葫芦与升降制动器,依靠摩擦在电机停止工作时,将荷载悬挂吊在任意位置的重要装置。起重机制动器在其中起着重要作用。

    盘式制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)器(qi),这(zhei)种制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)器(qi)依靠电(dian)(dian)磁(ci)控(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)、它(ta)装(zhuang)在穿过卷(juan)筒(tong)及减速器(qi)的(de)(de)(de)(de)快速轴上,当制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)器(qi)的(de)(de)(de)(de)电(dian)(dian)磁(ci)线圈电(dian)(dian)流中断时(shi),制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)片(pian)借助弹簧(huang)(huang)的(de)(de)(de)(de)张力(li)进行制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong),当起升电(dian)(dian)机运转时(shi),同时(shi)接通制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)器(qi)电(dian)(dian)磁(ci)铁的(de)(de)(de)(de)电(dian)(dian)流,依靠电(dian)(dian)磁(ci)的(de)(de)(de)(de)吸(xi)引力(li)将弹簧(huang)(huang)压缩,使制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)片(pian)松脱(tuo)。制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)器(qi)的(de)(de)(de)(de)弹簧(huang)(huang)是可以(yi)用(yong)调整螺丝进行调整的(de)(de)(de)(de),以(yi)保证制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)片(pian)之(zhi)间有足够(gou)的(de)(de)(de)(de)压力(li)及其相应的(de)(de)(de)(de)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)力(li)矩,这(zhei)样就可随时(shi)调整以(yi)保证制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)性能。使电(dian)(dian)动(dong)(dong)葫(hu)芦经常(chang)处于良好的(de)(de)(de)(de)工作状态。

    起重机制动器的电磁线圈引出线端6个,以适应电压220V或380V的接线需要。
