Description

新型挖掘机支耳组件箱体式结构
技术领域
本实用新型涉及一种新型挖掘机支耳组件箱体式结构,属于挖掘机技术领域。
背景技术
目前,挖斗的生产过程中,支耳组件部分都是由两个耳板、两个上边弯板、中弯板、下弯板和底板组成,耳板分别与上边弯板和中弯板焊接,然后上边弯板和中弯板的两端与下弯板焊接,而挖斗工作过程中底板、与耳板是受力最大的几个部位,在挖斗工作过程中经常发生焊道开裂和板材撕裂的问题,并且在生产过程中也很容易产生焊接变形,在大型挖斗的生产中尤其明显,所以如果可以减少焊道就会提高挖斗的使用寿命。 
发明内容
针对上述现有技术存在的问题,本实用新型提供一种新型挖掘机支耳组件箱体式结构,能有效地解决上述问题。 
为了实现上述目的,本实用新型采用的技术方案是:一种新型挖掘机支耳组件箱体式结构,包括耳板、下弯板和筋板,还包括上弯板,上弯板固定连接在下弯板上部,筋板分别与下弯板和上弯板固定连接,耳板固定连接在上弯板的上部。
本实用新型的有益效果是:安装方便,减小焊接缺陷的频率,减小焊道开裂的可能性,提高使用寿命。
附图说明
图1是本实用新型的结构示意图
图2是本实用新型的俯视图
图中:1、耳板,2、上弯板,3、筋板,4、下弯板。
具体实施方式
下面将结合附图对本实用新型作进一步说明。
如图1和图2所示,一种新型挖掘机支耳组件箱体式结构,包括耳板1、筋板3和下弯板4,其特征在于还包括上弯板2,上弯板2焊接在下弯板4上部,筋板3分别与下弯板4和上弯板2焊接,耳板1焊接在上弯板2的上部,采用整体式上弯板代替上边弯板和中弯板拼接的形式,这样就减少了焊道,从而减小了焊接缺陷的频率和焊道开裂的可能性,提高了挖斗的使用寿命。
