    摘要： A coring device has core drilling tool, a core catcher, a rock core barrel, a drilling machine outer cylinder, a flap valve and an inner rod for pulling the rock core barrel. The core catcher is provided inside the lower end of the rock core barrel. The core drilling tool includes an outer core tube and a hollow drill bit. The upper end of the outer core tube is connected to the lower end of the drilling machine outer cylinder. The lower end of the outer core tube is connected to the drill bit. The lower end of the inner rod protrudes into the rock core barrel and is movable axially by a certain distance relative to the rock core barrel. The flap valve includes a valve seat and a sealing flap. The valve seat is coaxially mounted on the inner wall of the drilling machine outer cylinder.

    摘要： A drilling control mechanism of a core drilling rig has a tooth drill and a core drilling rig. The core drilling rig is inside the tooth drill and engages with the drill in a sliding manner. A locking recess is formed at an inner wall of the tooth drill. A locking latch recess is formed at an outer wall of the core drilling rig and has a locking latch therein. The locking latch has a spring. When the locking recess is directly opposite the locking latch recess, the spring extends and the locking latch partially enters the locking recess. The core drilling rig has a central rod, a fluid channel activation module, an outer barrel, and outer barrel unlocking module and a flow diverging module. The central rod passes through the inner cavities of the fluid channel activation module, the outer barrel unlocking module and the flow diverging module.

    摘要： The present disclosure provides a rolling and sliding adaptive device for guiding and fixing a drill pipe. The rolling and sliding adaptive device includes a mounting platform, where the mounting platform is provided with a through hole for the drill pipe to pass through. Multiple rolling and sliding support mechanisms are arranged around the through hole. The rolling and sliding support mechanisms each include a support seat. The support seat is provided with a contact element telescopic and swingable on the support seat. A telescopic drive mechanism is provided between the contact element and the support seat. The contact elements on the multiple rolling and sliding support mechanisms form a funnel-shaped structure with a large upper part and a small lower part around the through hole. The rolling and sliding adaptive device is used on a deep in-situ high-fidelity coring calibration platform for accurate positioning of an assembly process of a multi-section drill pipe bin, thus ensuring the assembly accuracy of the multi-section drill pipe bin and stable support and fixation for the assembly and work of a coring system using the drill pipe.
