Storage tank detecting robot

Abstract

The invention discloses a storage tank detection robot which comprises a driving mechanism, a lifting mechanism, a guiding mechanism and a detecting mechanism. The driving mechanism comprises a driving wheel portion, a driven wheel portion, a distance adjusting portion, a driving bottom plate and a bearing wheel fixed onto the driving bottom plate. The lifting mechanism comprises a lifting motor,a rolling shaft and a lifting part, wherein the lifting motor is provided with an output shaft, and the rolling shaft is connected with the output shaft of the lifting motor. The guiding mechanism isprovided with a connector for guiding the lifting part, one end of the connector is fixed onto the driving bottom plate, and the other end of the connector is matched with the lifting part through a guide wheel. The detecting mechanism comprises a detecting bottom plate, a sensor box and a magnet, the sensor box is provided with a magnetic memory sensor, the storage tank detection robot can perform circular motion along a storage tank under driving of the driving mechanism, and the detecting mechanism can move up and down along the wall of the storage tank under driving of the lifting mechanism. The defected position of the storage tank can be accurately recognized, so that early diagnosis and flaw detection are performed on the storage tank.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a storage tank detection robot for detecting stress concentration and surface damage of the storage tank. Background technique [0002] Large storage tanks are special equipment for storing crude oil, liquid chemical raw materials and their products. They are widely used in many fields and play a positive role in my country's production and economic development. At present, many storage tanks in our country have been in service for a long time, and there are many defects. Leakage or even explosion accidents are very easy to occur at the defects, which will seriously damage the environment and threaten the safety of the staff. Therefore, the development of storage tank inspection methods and timely detection of storage tank defects can prevent accidents in advance. [0003] At present, the non-destructive testing technologies commonly used in the detection of larg...

AI Technical Summary

Problems solved by technology

Due to the uneven wall of the storage tank, there is a certain height of weld seam on the outside of the tank wall. When the robot crosses the weld seam, the distance between the robot and the tank wall surface increases, its adsorption force decreases, and the overturning moment increases, so there is Easy to overturn, fall off, etc.
