Quality detection device for shipbuilding steel plate butt-jointed seams

Abstract

The invention provides a quality detection device for shipbuilding steel plate butt-jointed seams, which comprises a detection tank, a detection tank hold-down mechanism, an alcohol jar, an alcohol detector, and an alarm. A seal rubber ring is arranged at the top of the detection tank connected with the alcohol jar through an air pipe. The detection tank hold-down mechanism comprises a support base board, a jack and clamping boards arranged at two ends of the support base board. The detection tank is arranged at the bottom of the shipbuilding steel plate butt-jointed seams, the support base board is arranged below the detection tank, the clamping boards at the two ends of the support base board are clamped on the shipbuilding steel plates, the jack is arranged between the support base board and the detection tank, the seal rubber ring is pressed on the bottom face of the shipbuilding steel plates which are located on two sides of one butt-jointed seam, the alcohol detector directly faces the top of the welding seam and is connected with the alarm through a signal line. By mean of the quality detection device for the shipbuilding steel plate butt-jointed seams, welding seam detection can be achieved before assembling and after butt welding of the shipbuilding steel plates, the detection is more simple and energy-saving, and the increased rework cost caused by welding seam defects after assembling can be effectively reduced.

Description

technical field [0001] The invention relates to a weld seam quality detection device, in particular to a quality detection device for butt weld seam of a ship steel plate. Background technique [0002] At present, the leakage inspection of most of the watertight cabins is carried out by filling the watertight cabins with water or air. Water detection mainly observes whether the outer surface of the welded seam of the watertight ship is leaking, but there are problems of water intake and drainage; air-inflated inspection needs to brush the foaming agent on the outer surface of the welded seam of the watertight ship, and observe the welded part of the watertight ship Whether there are blisters on the outer surface, the above two detection methods take a long time and high cost, and can only be detected for a sealed watertight ship room. [0003] Since the above-mentioned inspection method detects the sealed watertight ship room, it is basically close to the finished product. ...

Problems solved by technology

Water detection mainly observes whether the outer surface of the welded part of the watertight ship is leaking, but there are problems of water intake and drainage; air-inflated test needs to brush the foaming agent on the outer surface of the welded part of the watertight ship, and observe the welded part of the watertight ship Whether there are blisters on the outer surface, the above two detection methods take a long time and are expensive, and can only be detected for sealed watertight boat rooms

[0003] Since the above-mentioned inspection method detects the sealed watertight ship room, it is basically close to the finished product. Once there is a problem with the inspection quality of the weld (that is, leakage), it is difficult to make up for the weld defect, and it is impossible to butt weld the marine steel plate. After testing and before assembly, there is a quality problem that cannot eliminate the butt weld of marine steel plates from the source
