Image collection device for internal surface of long straight pipe

Abstract

The invention relates to the mechatronics field and discloses an image collection device for an internal surface of a long straight pipe. According to the image collection device for the internal surface of the long straight pipe, optical image collection is performed on the internal wall surface through an industrial camera; a positioning mechanism is formed by a servo motor which is installed on a working platform of a three-level cylinder, the three-level cylinder and a screw lifter; the industrial camera is installed at the front end of a cylinder rod of the three-level cylinder; the three-level cylinder is fixed inside a ladder-shaped hollow cylinder sleeve shaft; the ladder-shaped hollow cylinder sleeve shaft which is provided with a pair of rolling bearings is installed on a bearing base; a cylinder installation auxiliary which is arranged on the tail portion of the three-level cylinder is connected with a short shaft through flat keys; the short shaft is connected with the servo motor through a coupler; free adjustment of extensible length and rotating angles of an optical probe can be achieved due to the fact that the servo motor drives the three-level cylinder; a lifting mechanism of the working platform of the whole three-level cylinder is formed by the screw lifter and two rows of guide rails which are symmetrically vertically arranged; the height of the working platform of the three-level cylinder can be adjusted through a hand wheel of the screw lifter and the working platform of the three-level cylinder can be locked at an position during the moving up and down process.

Description

technical field [0001] The invention relates to an image acquisition device for the inner surface of a long straight tube, which is mainly used in the non-destructive detection of defects on the inner surface of a long tube, and belongs to the field of electromechanical integration. Background technique [0002] Endoscopic inspection is an important non-destructive inspection technology, which can be used for inspection and observation of places where high temperature, toxicity, nuclear radiation and human eyes cannot be directly observed. It can be realized without disassembling or destroying the assembly and stopping the operation of the equipment Non-destructive testing has been widely used in the detection and maintenance of automobiles, aero-engines, propellant grains, pipelines and other equipment. Compared with other non-destructive testing technologies, endoscopic testing is intuitive, efficient, and easy to operate. The location and nature of defects are monitored, ...
