Abstract

本实用新型涉及一种对称内外组合钩,包括基体、抓筒和抓杆,基体底部固定有抓杆和空心的抓筒,抓筒底部开口,抓杆位于抓筒内侧,抓筒内壁上和抓杆上分别设有斜向上的钩尖。本实用新型结构简单,工作效率高,可广泛用于打捞作业领域。

Description

对称内外组合钩
技术领域
本实用新型涉及一种打捞工具,特别是涉及一种对称内外组合钩。
背景技术
钩形打捞工具是用于从套管内或油管内部打捞各种绳类及其他落物,如钢丝绳、电缆、录井钢丝、刮蜡片等。目前的钩形打捞工具分为外钩形打捞工具和内钩形打捞工具,由于功能单一,所以针对不同的打捞物需要更换打捞工具,从而影响了工作效率。
发明内容
本实用新型克服了现有技术中的不足,提供了一种结构设计合理,打捞范围广的对称内外组合钩。
为了解决上述问题,本实用新型采用以下技术方案:
对称内外组合钩,包括基体、抓筒和抓杆,基体底部固定有抓杆和空心的抓筒,抓筒底部开口,抓杆位于抓筒内侧,抓筒内壁上和抓杆上分别设有斜向上的钩尖。
与现有技术相比,本实用新型的有益效果是:
本实用新型结构设计合理,将原来两种单一功能的工具合并在一起,打捞范围广,从而提高了打捞效果和打捞工作效率。
附图说明
图1为本实用新型结构示意图。
具体实施方式
对称内外组合钩,如图1所示,包括基体1、抓筒2和抓杆3,基体1底部固定有抓杆3和空心的抓筒2,抓筒2底部开口,抓杆3位于抓筒2内侧,抓筒2内壁上和抓杆3上分别设有斜向上的钩尖4。
本实用新型采用内外钩组合为一体的结构形式,可进行内外两部分钩捞,并互相起阻止落物弹出的作用,以保证捞获绳类落物,不致因本身的弹性而脱钩。
