Abstract

The invention provides a heat exchanger tube plate crawling robot direct drive transmission mechanism which comprises a machine-mounted box, a motor is arranged in the machine-mounted box, a harmonic reducer is arranged on a top cover of the machine-mounted box, the motor is directly connected with the harmonic reducer, and the harmonic reducer directly drives a load. According to the direct-drive transmission mechanism of the heat exchanger tube plate crawling robot, a transmission chain of the positioning robot is reduced, and the complexity of a transmission part is reduced, so that the rotation precision of the positioning robot is improved, the inspection efficiency is improved, the service life of a probe is prolonged, and the radiation dose level of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of steam generator heat transfer tubes, in particular to a direct-drive transmission mechanism of a heat exchanger tube plate crawling robot. Background technique [0002] Nuclear power plants have a wide variety of heat exchangers and pressure-bearing equipment, which must be non-destructively tested in accordance with certain specifications before they are put into operation and after they are put into operation. Due to the characteristics of the nuclear industry, these devices either operate under radioactive conditions, or are subject to high temperature and high pressure (tension) and fluctuate frequently, so their inspection cycles are more frequent than other industries. At the same time, in order to avoid the consequences of radioactive leakage, its inspection technology, inspection specifications and other related requirements are also more stringent. The heat transfer tu...
