BG型钻杆排放设备的设计与应用

Design and Application of BG Pipe Handler

传统接卸钻杆多采用人工对扣、拖拽摆放方式,效率较低,工人劳动强度大。针对目前流行的可抬头式全液压钻机,设计了一种BG型自动钻杆排放设备,该设备通过机械手与夹持器2个机构与抬头式动力头配合完成钻杆的自动化接卸、摆放。详细介绍了机械手结构设计与回转驱动选型、夹持器结构设计与夹持油缸选型以及液压系统的设计思路,从理论上确定设备的可靠性。最后通过现场试验验证了BG型自动钻杆排放设备的实用性。

Manual centering and placing drill pipes are the main methods of traditional way to load and unload drill pipes, which is inefficient with high labor intensity.To improve this unfavorable situation, BG mechanical pipe handler is devel-oped to match with hydraulic rigs with tilting power head, it can accomplish loading/unloading and placing drill pipes me-chanically by coordinating the manipulator and the clamping holder with tilting power head.This paper introduces in detail the structural design of the manipulator and rotary driving selection, the structural design of the clamping holder and clam-ping cylinder selection and the design idea of hydraulic system, in order to determine the reliability of this equipment in theory.The practicability of BG mechanical pipe handler is proved by field test.
