Description

新型气动卡盘
技术领域:
本实用新型涉及一种钻、修井作业中卡持钻杆、油管的动力工具。
背景技术:
现有的气动卡盘卡持管柱的卡瓦为二片式,卡瓦牙为多片式,提升机构为杠杆式,不能同时通过管柱及油泵电缆,管柱受力不均匀,易变形。
发明内容:
本实用新型的目的在于提供一种结构合理,卡持可靠,管柱受力均匀,不易变形的新型气动卡盘。
本实用新型的技术解决方案是:
一种新型气动卡盘,有卡盘体、卡瓦组件、提升机构,其特征是:有两个卡瓦组件,每个卡瓦组件由两个连接在摆杆一端的卡瓦组成,摆杆的另一端与曲柄连杆式提升机构的曲轴连接,卡瓦上装牙板。
卡盘体上装活门,活门上设有通过油泵电缆的通孔。
本实用新型结构合理,新颖,操作方便,管柱受力均匀,卡持可靠,能同时通过管柱及油泵电缆,在油田修井作业中免除拆卸油泵,安装、使用、维护方便。
附图说明:
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型一个实施例的结构示图。
图2是图1的俯视图。
图3是图1的后视图。
具体实施方式:
一种新型气动卡盘,有卡盘体1、卡瓦组件、提升机构,有两个卡瓦组件,每个卡瓦组件由两个连接在摆杆4一端的卡瓦2、3组成,摆杆4的另一端与曲柄连杆式提升机构的曲轴5连接,曲柄连杆式提升机构有与左右曲轴5连接的连杆6和汽缸7组成,卡瓦上装牙板8。卡盘体1上装活门9、活门销10,活门9上设有通过油泵电缆的通孔11。
