Grasping finger type pipe clamping device

A gripping finger type pipe clamping device comprises an opening slip, a gripping and releasing hydraulic cylinder, a working in-position hydraulic cylinder and a fixing frame, the working in-position hydraulic cylinder is installed on the fixing frame, the gripping and releasing hydraulic cylinder is connected with a piston rod of the working in-position hydraulic cylinder, and the opening slip is connected with a piston rod of the gripping and releasing hydraulic cylinder. The device is simple in structure and can act independently, the piston rod of the working in-place hydraulic cylinder is withdrawn or pushed out, and the piston rod of the gripping and releasing hydraulic cylinder is pushed out or withdrawn, so that the oil pipe is clamped and released, the purpose of gripping the finger type opening slip to clamp the oil pipe is achieved, the oil pipe can be clamped in time, and the oil pipe in a well is prevented from flying out. 一种攥握手指式卡管装置，包括开口卡瓦、握紧释放液压缸、工作就位液压缸和固定架，工作就位液压缸安装在固定架上，握紧释放液压缸与工作就位液压缸的活塞杆
