Hydraulic Tool Catcher

The tool catcher is a safety device, which is installed between the seal head and the lubricator, it is mainly used for automatically grasping rope socket when tools are connected underground and are lifted to the top end of the lubricator, thereby effectively preventing cables from falling off the cable head or instruments drop in well when the cable is broken or the rope socket is impacted on the bottom end of the seal head because of the very fast pulling speed or over big pull force. When release the rope socket , should use the hydraulic control system for pressurizing to lead the hydraulic force to push the piston in the tool catcher and the robotic gripper, the piston drives the robotic gripper which is opened, and then release the rope socket. The upper end connect the grease injection seal head choke flow tube directly, and the safety choke flow ball valve is designed on it, once the cable falling off or broken from the cable head accidentally, under the function of the high pressure flow or the airflow, the safety choke flow ball valve can plug the cable hole to choked flow and seal wellhead automatically.
