摘要： A rod support system has an upper gripper assembly and a lower gripper assembly. Each gripper assembly has a top plate having a first track. The first track has a first substantially arcuate portion having a first radius of curvature and a second substantially arcuate portion having a second and smaller radius of curvature. A jaw is constrained to move in a path defined by the first track. A bottom plate of the assembly has a second track that is congruent with the first track also engaging the jaw, so that the jaw is constrained to move in a path defined by the first track and the second track in cooperation. The jaws can support a rod when the jaws move from a position along the first arcuate portion of the first and second tracks to a position along the second arcuate portion of the first and second tracks.

摘要翻译： 杆支撑系统具有上夹具组件和下夹具组件。 每个夹具组件具有具有第一轨道的顶板。 第一轨道具有具有第一曲率半径的第一基本弧形部分和具有第二和较小曲率半径的第二基本上弧形部分。 钳口被限制在由第一轨道限定的路径中移动。 组件的底板具有与第一轨道一致的第二轨道，其也接合钳口，使得钳口被限制为在由第一轨道和第二轨道限定的路径中协作地移动。 当夹爪从沿着第一和第二轨道的第一弧形部分的位置移动到沿着第一和第二轨道的第二弧形部分的位置时，夹爪可以支撑杆。

摘要： A system for automated drilling rod changing has an upper position sensor capable of sensing the position of the rotary head with respect to the deck, and a lower position sensor also capable of sensing the position of the rotary head with respect to the deck. The position sensors have respective electrical outputs connected to a computer. The computer is programmed to compute the vertical position of the rotary head with respect to the deck at a first position, where a first rod is suspended above a second rod held by the table clamp, and at a second position, where the box end of the first rod is capable of being connected to the pin end of the second rod, based on the computed position of the rotary head; and, the computer is programmed to command the rotary head to move from the first position to the second position.
