The invention provides a double-hoisting-point fixed winch. The double-hoisting-point fixed winch comprises a rack, a driving mechanism and winding mechanisms; the driving mechanism, the winding mechanisms, braking mechanisms and a mounting mechanism are installed on the rack separately; and the driving mechanism is in transmission connection with the winding mechanisms and used for driving the winding mechanisms so that the winding mechanisms can rotate around their central axes for winding and/or releasing traction ropes. The double-hoisting-point fixed winch further comprises the braking mechanisms and the mounting mechanism; and each braking mechanism comprises a first brake disc and a second brake disc, wherein the side, close to the second brake disc, of the first brake disc is provided with a convex block, and one side of the second brake disc is fixedly connected with one end of the corresponding winding mechanism. According to the double-hoisting-point fixed winch, the first brake disc is provided with the convex block, the second brake disc is provided with an annular groove, when the surfaces of the first brake disc and the second brake disc are attached, the convex block and the annular groove are also attached, the friction contact area of the first brake disc and the second brake disc is increased, and the braking effect is improved.
本发明提供一种双吊固定式卷扬机,包括机架、驱动机构、收卷机构;所述驱动机构、收卷机构、制动机构和安装机构分别安装在所述机架上;所述驱动机构和收卷机构传动连接,所述驱动机构用于驱动所述收卷机构,使所述收卷机构可绕自身中轴线转动,用于收卷和/或释放牵引绳;还包括制动机构和安装机构;所述制动机构包括第一刹车盘和第二刹车盘;所述第一刹车盘上靠近第二刹车盘的一侧设置有凸块;所述第二刹车盘的一侧与所述收卷机构的一端固定连接。本发明通过在第一刹车盘上设置凸块,在第二刹车盘上设置环形凹槽,在第一刹车盘和第二刹车盘表面贴合的同时,凸块和环形凹槽也贴合,增加了两者的摩擦接触面积,增加制动效果。
