Abstract

The present invention relates to a hinge bearing and testing equipment, comprising a first bracket mechanism; a rotating mechanism, which is rotationally connected with the bracket mechanism; a connecting shaft, which is drivingly connected with the rotating mechanism, and one end of the connecting shaft is It is fixedly connected with one end of the measured object; the rotation axis of the connecting shaft is perpendicular to the rotation axis of the rotating mechanism. When testing, the object under test bends downward, driving the connecting shaft to tilt downward to automatically adjust the angle, which can reduce the abnormal stress concentration at the connecting end of the object under test and the connecting shaft, and avoid affecting the test effect of the whole set of testing equipment.

Description

technical field [0001] The invention relates to the technical field of drilling and logging instrument testing, in particular to a hinged shaft support and testing equipment. Background technique [0002] The intelligent pilot drilling system is a relatively advanced drilling and logging tool in the petroleum field. When working 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 process of downhole drilling in the laboratory environment, and then judge the drilling and logging instruments and drilling tools (including ordinary oil drilling and logging) by means of testing. The indicators of the instrument) are normal, so as to judge its performance stability, reliability and service life. The shape of the tools un...
