Abstract

本发明公布了一种消防抢险用新型液压剪扩器，该剪扩器的刀身通过销轴与夹板铰接，两个刀身的铰接点形成一定间距，夹板固定在套筒上，套筒与油缸外壳连接，刀身的刀柄端部与连杆一端铰接，连杆的另一端与活动连接件铰接，活动连接件连接在活塞前端；本发明剪切和扩张两种功能都是由油缸的推力实现的，剪力和扩张力都能很大。

Description

新型液压剪扩器
技术领域
本发明涉及一种救灾，抢险，救援用新型液压剪扩器。
背景技术
随着社会经济的发展，救援人员担负着越来越多的抢险救援任务，其中，液压剪和液压扩张器是不可缺少的工具，现行使用的剪扩器的剪切功能是靠推力实现，扩张功能是靠油缸拉力实现，其剪切力和扩张力差距很大，扩张力相对剪切力很小。
发明内容
本发明的目的是：提供一种救灾，抢险，救援用新型液压剪扩器，剪切功能和扩张功能都是由油缸的推力实现，使剪切和扩张两个力都很大。
本发明的技术方案是：一种新型液压剪扩器，该剪扩器的刀身通过销轴与夹板铰接，两个刀身的铰接点形成一定间距，夹板固定在套筒上，套筒与油缸外壳连接，刀身的刀柄端部与连杆一端铰接，连杆的另一端与活动连接件铰接，活动连接件连接在活塞前端，活塞在推进的第一阶段，是实现剪切功能，在这一阶段活塞向前推进，推动连杆，连杆推动刀柄端部，使刀身绕销轴从外向里旋转，完成剪切功能，推进的第二阶段是实现扩张功能，活塞从第一个阶段完成的位置继续向前推进，此时连杆由推动刀柄端部转变为拉动刀柄端部，使刀身绕销轴从里向外转动，完成扩张功能。
本发明的有益效果是
剪切和扩张两种功能都是由油缸的推力实现的，使剪力和扩张力都很大。
附图说明
下面结合附图和实施例对本发明作进一步的描述：
图1为本发明的初始状态
图2为本发明的剪切状态
图3为本发明的扩张状态
图4为本发明的完全扩张状态
其中：1刀身；2连杆；3夹板；4油缸外壳；5活动连接件；6活塞；7销轴；8刀柄端部；9套筒；10进油口。
具体实施方式
如图1，图2，图3，图4所示，一种新型液压剪扩器，该剪扩器的刀身1通过销轴7与夹板3铰接，两个刀身1的铰接点形成一定间距，夹板3固定在套筒9上，套筒9与油缸外壳4连接，刀身1的刀柄端部8与连杆2一端铰接，连杆2的另一端与活动连接件5铰接，活动连接件5连接在活塞6前端，活塞6在推进的第一阶段，是实现剪切功能，在这一阶段活塞6向前推进，推动连杆2，连杆2推动刀柄端部8，使刀身1绕销轴7从外向里旋转，完成剪切功能，推进的第二阶段是实现扩张功能，活塞6从第一个阶段完成的位置继续向前推进，此时连杆2由推动刀柄端部8转变为拉动刀柄端部8，使刀身1绕销轴7从里向外转动，完成扩张功能。
