Abstract

The invention relates to a mechanical micro-sample rapid sampling mechanism, comprising: a base: a horizontal shaft is arranged on the top; a tool unit: includes a rotary motor and a sampling tool connected with the rotary motor, and the rotary motor is rotatably connected with the horizontal shaft; a swing unit : connected with the upper end of the rotating motor, used to drive the rotating motor to swing around the horizontal shaft. Compared with the prior art, the present invention can realize high-efficiency digging of button-type or spherical-cap-type materials.

Description

technical field [0001] The invention relates to the technical field of pressure vessel inspection, in particular to a mechanical micro-sample rapid sampling mechanism. Background technique [0002] In my country's petrochemical, electric power and other industries, there are many pressure pipelines and other equipment that serve in harsh environments. These equipment have been operating under high temperature, high pressure, hydrogen corrosion and other conditions for a long time, and the service environment is very harsh. In order to ensure safety within the service period, these pressure equipment are often designed with a higher safety factor and a larger safety margin to improve safety. Considering the requirements of economy and safety, people hope to know the mechanical properties of the equipment in a timely and accurate manner without affecting the service of the equipment, so as to evaluate the performance degradation in time. The small punch test or the hydraulic ...
