Rolling and sliding adaptive device for guiding and fixing drill pipe
Abstract:
A rolling and sliding adaptive device for guiding and fixing a drill pipe 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.
