Abstract

本实用新型涉及一种WK-4型电铲斗臂的上档板,包括上档板,其特征是上档板为梯形,设有两个通孔。本实用新型在结构上提高了强度,增大了上档板的承载能力,使用寿命得到提高,制造工艺和结构更简单。

Description

一种电铲斗臂上档板
技术领域
本实用新型涉及一种挖掘机电铲斗臂上的零部件,尤其是露天矿山WK-4型电铲斗臂的上档板。
背景技术
目前,电铲斗臂的上档板呈凸形结构,两边比较单薄电动挖掘机在采掘过程中,电铲斗臂的上档板承受载荷大,长时间工作易造成上档板断裂,上档板开裂位置大都在两边薄壁处,更换上档板很繁琐,处理时间长,给生产带来不便。
发明内容
本实用新型的目的是要提供一种强度更大的电铲斗臂上档板。
本实用新型的目的是这样达到的:所述上档板形状由原来的凸形改为现在的梯形,所述上档板设有两个通孔。
本实用新型具有结构简单,强度提高,使用寿命长等特点。
附图说明
图1、现有上档板结构示意图
图2、本实用新型结构示意图
具体实施方案
对照图1可知,现有上档板为凸形,频繁承受载荷时容易在两边薄壁1处断裂。
对照图2可知,该上档板2为梯形,设有两个通孔3。
