Abstract

一种广泛用于石油钻井修井作业的各种动力钳和卡瓦的圆弧面圆弧齿合成牙板，包括底板和齿部，齿部的齿表面设置成圆弧齿面，其半径相当于钻井圆管柱钻具的半径，使二者能有效抱合；在牙板圆弧齿面上制作对称圆弧齿组相啮合成多向多角多刃的齿形，使牙板的牙齿都能与圆管柱钻具有效啮合，牙板的工作抱合面和夹持的轴向力和径向力得到增大。本实用新型结构合理可靠，使用寿命长，减轻圆管柱钻具的损伤，达到降本减排的环保经济效果。

Description

圆弧面圆弧齿合成牙板
技术领域
本实用新型涉及石油钻井修井作业的圆弧面圆弧齿合成牙板
背景技术
各种石油钻井动力钳和卡瓦采用牙板“咬住”钻杆、套管、油管等圆管柱钻具来进行作业。牙板的承载力非常大，故对牙板的强度和齿形要求都很高。专利号90102517动力钳采用平面直齿，弧面直齿和平面弧齿等牙板。直齿的齿向与钻具的重力方向一致，夹持效果较差。平面弧齿牙板的平面齿面与圆管柱接触处于相切位置，往往只有牙板中间二路牙齿能切进钻具受力，而两侧的牙齿则较少切进钻具体，因此牙板的受力工作齿面只有整个牙板齿面的1/2左右，直接影响到牙板的使用寿命和钻井的工作质量和进度，还易损伤钻杆等钻具。牙板是钻井需求量非常大的配件，因此增长牙板的使用寿命，保证了钻井的工作质量和进度，而且能节约大量合金钢材料和机加工及热处理的能源消耗，对降本减排有很大现实意义。
发明内容
本实用新型的目的是提供一种牙形合理，使用寿命长，工作可靠，减轻钻井钻具损伤的圆弧面圆弧齿合成牙板。
本实用新型解决其技术问题新采用的技术方案是：一种圆弧面圆弧齿合成牙板，包括底板和齿部，其与现有技术不同之处是，牙板的齿部设置成圆弧面与对称圆弧齿组相交合成多向多角多刃的齿形，使牙板的牙齿都能与圆管柱钻具有效咬合，牙板的工作抱合面和夹持的轴向力和径向力得到增大。
本实用新型的有益效果是：本实用新型结构合理可靠，对提高牙板的使用寿命，保证钻井的工作质量和进度，减轻圆管柱钻具的损伤效果明显，达到降本减排的环保经济效果。
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是根据本实用新型提出的结构图。
图中1.底板，2.齿部，3.圆弧齿面，4.对称圆弧齿组。
具体实施方式
一种圆弧面圆弧齿合成牙板，包括底板1和齿部2，齿部2的齿表面设置成圆弧齿面3，其半径相当于圆管柱钻具的半径，使二者能有效抱合；在牙板圆弧齿面上制作对称圆弧齿组4相交合成多向多角多刃的齿形，使牙板的牙齿都能与圆管柱钻具有效咬合，牙板的工作抱合面和夹持的轴向力和径向力得到增大。
