    • A fluid operated impact drilling tool has a hammer slidably mounted in a casing connected to a string of drilling pipe. Inside the casing above the hammer is mounted a valve. Both the valve and hammer have reciprocal sliding movement along the longitudinal axis of the tool to substantially interrupt flow of a drilling fluid therethrough. Movement of the valve and hammer predominantly results from different pressures acting on separate pressure areas of the valve and hammer. The hammer may impact either an anvil or a bit attached thereto. Wear on the valve and hammer is reduced by smooth, hardened surfaces at locations subject to wear. A trapped fluid may also be used in an alternative embodiment to dampen the shock effect of the valve as it reaches its upper and lower stops.
    • 流体操作的冲击钻具具有可滑动地安装在连接到钻杆系列的壳体中的锤。 在锤子的上方的壳体内安装有阀。 阀和锤均具有沿着工具的纵向轴线的往复滑动运动,以基本上阻止钻井液体流过其中。 阀和锤的运动主要来自作用在阀和锤的不同压力区上的不同压力。 锤子可能会影响砧座或连接在其上的钻头。 阀门和锤子上的磨损在磨损位置的平滑,硬化的表面减少。 在替代实施例中,也可以使用被捕获的流体,以便在到达其上部和下部停止点时抑制该阀的冲击效应。

    • An impact drilling apparatus has an anvil inside a casing for receiving impact blows from a hammer. The lower end of the anvil is threadably connected to a drill bit having an external load bearing shoulder. On the lower end of the casing is attached a driver guide sub which extends downwardly around the threaded connection between the drill bit and anvil to bear on the external load bearing shoulder for transmitting down weight to the bit and simultaneously counteracting lateral forces acting on the bit and anvil. A spline connection is provided between the driven guide sub and the anvil. In the off bottom position, a shoulder of the anvil comes to rest against the top of the driver guide sub which stops the reciprocating action of the hammer while drilling fluid continues to flow.
    • 冲击钻孔装置在壳体内具有用于接收来自锤的撞击的砧座。 砧座的下端螺纹连接到具有外部承载肩部的钻头。 在壳体的下端安装有驱动器引导件,其沿着钻头和砧座之间的螺纹连接向下延伸以承载在外部承载台肩上,用于将重量向下传递到钻头并同时抵消作用在钻头上的横向力 和铁砧。 在被驱动的导向部分和砧座之间提供花键连接。 在底部位置,砧座的肩部靠在驾驶员引导件的顶部上,停止锤子的往复运动,同时钻井液继续流动。

    • A fluid operated impact drilling device wherein a hammer is mounted in a casing for axial reciprocating movement and drilling fluid flows through the hammer. The flow of drilling fluid is controlled by a valve element at the upper portion of the hammer. Differential pressure areas are provided in the flow path of the drilling fluid which coupled with the action of the valve element causes the hammer to be repeatedly lifted up into the valve element and then driven downward against an anvil by the force of the drilling mud. The valve element remains partly open, thereby preventing excessive backpressures from damaging the drill pipe or equipment. The drilling device is attached immediately above the drill bit with the drill bit being secured to the anvil. A catcher device is mounted to stop the reciprocating impact action of the hammer against the anvil upon picking the bit up off bottom.
    • 一种流体操作的冲击钻井装置,其中锤安装在用于轴向往复运动的壳体中,并且钻井流体流过锤。 钻井液的流动由锤的上部的阀元件控制。 在钻井液的流动路径中提供差压区域,其与阀元件的作用相结合,使得锤被重复地提升到阀元件中,然后通过钻井泥浆的力向下抵靠砧座向下驱动。 阀元件保持部分打开,从而防止过大的背压损坏钻杆或设备。 钻头装置紧紧地安装在钻头上方,钻头固定在砧座上。 捕获器装置被安装成在底部拾取钻头时停止锤子对砧座的往复冲击作用。
