Description

摆轮式八绳交叉防摇装置
技术领域
本实用新型属于一种集装箱的吊具,具体涉及一种对集装置摆轮式八绳交叉防摇装置。
背景技术
集装箱起重机在作业的过程中,会产生摇摆,摇摆如果过于剧烈则存在安全隐患,现有的集装箱起升装置大致分为以下几种类型:第1种:在吊具上采用四滑轮八绳平衡起升,无另外的防摇装置,此种装置主要应用于内河港口,在集装箱起吊和运转过程中会产生较大的摇晃,不利于起吊的安全,同时也降低了工作效率。第2种:采用四滑轮八绳吊具,另加双向交叉防摇钢绳,实现柔性防摇,但是不足之处在于需要单独设置防摇系统,使吊具结构更为复杂,并增加了成本。第3种:采用刚性起升导向臂,实现刚性防摇,但是刚性防摇对位性很差,使作业率降低。第4种:采用八根起升钢丝绳交叉斜拉吊具,即在吊具上固定八个绳点,实现起升和防摇的功能,但是采用八绳固定的方法,集装箱在起升的过程中易造成受力不均匀,导致钢绳寿命短,易瞬时超载,不安全。
发明内容
为了克服现有集装箱吊具的不足,本实用新型提供一种摆轮式八绳交叉防摇装置,本实用新型解决其技术问题所采用的技术方案是:
一种摆轮式八绳交叉防摇装置,包括钢丝绳、起升卷筒和导向滑轮,其特征在于:还包括摆动轴滑轮,每个起升卷筒上绕出的钢丝绳绕过导向滑轮后,分别交叉绕过两侧的摆动轴滑轮,钢丝绳的固定端固定在小车上;
所述钢丝绳的固定端设置在与钢丝绳经过的摆动轴滑轮相对的一侧,形成双向交叉;
所述吊具上设有四个固定点;
所述导向滑轮为固定滑轮;
本实用新型的有益效果:采用本吊具防摇装置可以实现双向防摇,不需要另外的防摇系统;采用摆轴式滑轮技术,起升钢丝绳受力均衡,即使集装箱惯性摆动时,也能克服集装箱摆动而引起的钢丝绳受力不均的情况,避免由于钢丝受力过大而出现断绳的危险。
附图说明
图1为本实用新型结构示意图;
附图1、钢丝绳  2、起升卷筒  3、导向滑轮  4、摆动轴滑轮
具体实施方式
一种摆轮式八绳交叉防摇装置,包括钢丝绳1、起升卷筒2和导向滑轮3,还包括摆动轴滑轮4,在使用吊具防摇装置时,每个起升卷筒2上绕出的钢丝绳1绕过导向滑轮3后,分别交叉绕过两侧的摆动轴滑轮4,钢丝绳1的固定端固定在小车上,钢丝绳1的固定端设置在与钢丝绳1经过的摆动轴滑轮4相对的一侧,形成双向交叉,摆动滑轮主要是为了克服起升过程中钢丝绳1角度的变化,吊具上设有四个固定点,而每个固定点都设置有摆动轴滑轮4,导向滑轮3为固定滑轮。
由于集装箱吊具在起升过程中由于钢丝绳1的角度会产生变化,而四个滑轮除了绕其固定轴转动外,还可绕另外一根轴摆动,保证了钢丝绳1与滑轮平面一致,实现起升和双向防摇的功能。
