Abstract: 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.

Abstract: An acoustic emission probe positioning system, a test block for the system, and an application of the system are disclosed. The positioning system comprises a first test block and a second test block that are oppositely arranged and that define a non-closed test region. The first test block includes a first main portion and a first protruding portion that are connected to each other. The second test block includes a second main portion and a second protruding portion that are connected to each other. The first main portion and the second main portion are vertically opposite to each other, and the first protruding portion and the second protruding portion are opposite to each other left and right in a staggered manner. Multiple first probe storage holes are defined in the first main portion, and multiple second probe storage holes are defined in the first protruding portion. Multiple third probe storage holes are defined in the second main portion, and multiple fourth probe storage holes are defined in the second protruding portion. The first probe storage holes, the second probe storage holes, the third probe storage holes, and the fourth probe storage holes are each used for accommodating an acoustic emission probe.
