Abstract

The invention relates to a hinged shaft support and test equipment. The hinged shaft support comprises a first bracket mechanism, a rotating mechanism which is rotationally connected with the bracketmechanism, and a connecting shaft which is in transmission connection with the rotating mechanism, and one end of the connecting shaft is used for being fixedly connected with one end of a measured object. The rotating axis of the connecting shaft is perpendicular to the rotating axis of the rotating mechanism. During testing, the tested object is bent downwards to drive the connecting shaft to incline downwards to automatically adjust the angle, so that abnormal stress concentration at the connecting tail end of the tested object and the connecting shaft can be reduced, and the test effect ofthe whole set of test equipment can be prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of drilling and logging instrument testing, in particular to a hinge shaft support and testing equipment. Background technique [0002] The intelligent drilling guide system is a relatively advanced drilling and logging tool in the petroleum field. When working in the downhole, the maximum bending angle is 18° / 30 meters and the maximum speed is 200r / min. In order to verify the environmental adaptability and reliability of the system, Mechanical strength and fatigue life, it is necessary to simulate the working state of drilling and logging instruments and drilling tools in the downhole drilling process in the laboratory environment, and then judge the drilling and logging instruments and drilling tools (including ordinary oil drilling and logging The indicators of the instrument) are normal, so as to judge its performance stability, reliability and service life. The shape of downhole tools for intelligent d...
