Abstract

本实用新型公开了一种液压支架伸缩梁加长结构,包括伸缩梁(1),伸缩梁(1)前端安装有弯板(2),弯板(2)上穿孔,通过螺栓(5)和加长板(3)连接。采用加长结构的伸缩梁,将前方岩层托住,防止碎石大量掉落影响伸缩梁下方的设备工作。

Description

一种液压支架伸缩梁加长结构
技术领域
本实用新型涉及液压支架的伸缩梁。 
背景技术
现有液压支架顶部的伸缩梁较短,在岩层较为松软的地区时工作时,前方的岩层被伸缩梁碰一下就会剥落,而伸缩梁又比较短,岩石就会大量的掉落到伸缩梁下方,影响液压支架工作。 
发明内容
本实用新型要解决的技术问题:针对现有的液压支架不适应开采松软煤层的问题,提供了一种将伸缩梁加长的结构。 
本实用新型技术方案: 
一种液压支架伸缩梁加长结构,包括伸缩梁,伸缩梁前端安装有弯板,弯板上穿孔,通过螺栓和加长板连接。
弯板和加长板的交接处安装一块加强板。 
加长板的下侧有加强筋。 
本实用新型有益效果: 
采用加长结构的伸缩梁,将前方岩层托住,防止碎石大量掉落影响伸缩梁下方的设备工作。
附图说明:
图1为本实用新型结构示意图。
图2为本实用新型仰视结构示意图。 
具体实施方式:
如图,在伸缩梁1前端的弯板2上钻一排孔,然后将加长板3和弯板2对接,加长板3上表面是平面,下侧有加强筋,两侧和后侧有护板,护板上也有孔,用螺栓5穿过这两个排孔将弯板2和加长板3连接在一起,然后在弯板2和加长板3的结合处焊接一块加强板4。

Claims (3)

1.一种液压支架伸缩梁加长结构,包括伸缩梁(1),其特征在于:伸缩梁(1)前端安装有弯板(2),弯板(2)上穿孔,通过螺栓(5)和加长板(3)连接。
2.根据权利要求1所述的液压支架伸缩梁加长结构,其特征在于:弯板(2)和加长板(3)的交接处安装一块加强板(4)。
3.根据权利要求1所述的液压支架伸缩梁加长结构,其特征在于:加长板(3)的下侧有加强筋。
