Description
Technical field
The present invention relates to weld seam detection technical field, more particularly to a kind of weld seam for continous way large-scale storage tank bottom plate to examine
Survey instrument.
Background technology
Because large-scale storage tank bottom plate has one side to be close on the ground so that bottom plate butt weld can only carry out single-sided welding,
And weld seam single-sided welding quality is poor compared with two-sided welding quality, therefore the detection to large-scale storage tank bottom plate weldquality is very heavy
Will.But kerosene detection, full water test, inflation leak test etc. commonly use simple and effective detection method for quality of welding line, are not suitable for big
The detection of type storage tank bottom plate weld seam, therefore, occurs the detection of large-scale storage tank bottom plate weldquality local vacuum-pumping in the prior art
Method：It is covered with weld seam inspection vacuum measuring tank in large-scale storage tank bottom plate face of weld position brushing suds, weld seam inspection vacuum detecting case
Inside vacuumize, whether observation vacuum detecting case inside weld surface produces bubble, so that it is determined that whether weld seam has leakage point.
Such a detection method positive effect, so as to by the use of many businessmans, connect as disclosed on patent application text
Continuous formula large-scale storage tank bottom plate weld joint vacuum detector（Application number：201320631673.8）, welded in continous way large-scale storage tank bottom plate
Display, camera, minipump, deflecting roller, BOGEY WHEEL, dividing plate, suds brush are provided with seam vacuum detection instrument.This
Technical scheme when carrying out weld joint vacuum detection operation can to the automatic application suds of weld seam, testing staff push with-
The continous way large-scale storage tank bottom plate weld joint vacuum detector of more than 40KPa vacuums, slowly being walked along weld seam can be to weld seam
Carry out vacuum detecting；The technical scheme overcomes the problem that current normal weld vacuum detection instrument can not be detected continuously, for drop
Low large-scale storage tank bottom plate weld seam detection working strength, raising detection efficiency have positive effect.
But due to the suds cabin limited volume in the detector, detected for continous way large-scale storage tank bottom plate
When, the phenomenon that the soap aqueous in suds cabin is finished often occurs, now has to stop detection work, carries out to soap
The supply work of water tank, so as to again result in the detection discontinuous phenomenon of work, and reduce operating efficiency.
