摘　　要：本文介绍了一种单次只能抓取单杆管柱排管机械手用的扶持钳装置,其可用于二层台排管机械手或钻台机械手,进行对钻铤、钻杆、油管及部分套管的扶持排管作业。该扶持钳装置通过增加主钳指驱动液压缸的导向功能,增长了主钳指驱动液压缸的使用寿命;通过增加连杆数量提高了扶持钳的强度,降低了管柱别开主钳指,发生管柱脱出扶持钳的风险。同时,该扶持钳装置通过改变左右主钳指组件的开度,以实现直径粗细不同的管柱使用同一夹钳夹持的功能;通过管柱挡块改变钳口深度,以避免扶持钳同时夹持两根细管柱的意外情况发生,通过传液压缸感器信号检测和司钻房主控制系统的计算,从而可以实现机械手排管作业完全自动化的目的。This paper introduces a kind of support clamp device that can only grab the single pipe string for the manipulator, which can be used for the pipe discharge manipulator of monkey-board or drill floor manipulator to support the drill collar, drill pipe, tubing and part of the casing. The supporting tong device increases the service life of the main tong finger driving hydraulic cylinder by increas-ing the guiding function of the main tong finger driving hydraulic cylinder;by increasing the num-ber of connecting rods, the strength of the clamp device is improved, and the risk of the pipe string falling out of the clamp device is reduced. At the same time, the supporting tong device can realize the function of using the same clamp to clamp the pipe strings with different diameters and thick-nesses by changing the opening of the left and right main tong finger components;the depth of the jaw is changed by the pipe column stopper to avoid the accidental situation that the clamp device holds two thin pipe strings at the same time. The purpose of complete automation of the manipula-tor pipe arrangement can be achieved by transmitting the signal detection of the hydraulic cylinder sensor and the calculation of the driller’s main control system.
