Be to guarantee the sealing in cover plate, the face of weld and face of weld space that contact plate forms, be stained with cellular rubber on the described weld seam covering box, itself and face of weld surface of contact.
Be the testing result of Real Time Observation tightness of welding lines, described weld seam covers box and adopts transparent material to make.
Weld seam covers box owing to breakage occurs external pressure when preventing from detecting, and is provided with support bar in weld seam covering box inside.
Described weld seam covers box and is provided with tensimeter, and tensimeter connects by the inner chamber that the pressure tapping on the cover plate and weld seam cover box.
The pipeline that described weld seam covers box and vacuum extractor is provided with switch.
The beneficial effects of the utility model are: adopt and should can just can carry out tightness test to the watertight fillet weld in the body section stage at boatbuilding oceangoing ship tightness of welding lines pick-up unit, the ship section can be carried out the integrality application, reduced the step of stickily tear adhesive tape, assurance weld seam periphery enamelled coating is not damaged, greatly alleviate the labour, shortened shipbuilding period.This apparatus structure is reasonable, easy to use, can carry out close property testing to the weld seam of difformity, position.

Accompanying drawing 3 covers the 3rd structure of box and the synoptic diagram of being combined with the face of weld for the utility model weld seam.
Among the figure, 1, weld seam covers box, 2, vacuum extractor, 3, pipeline, 4, cellular rubber, 5, tensimeter, 6, support bar, 7, the face of weld, 8, weld seam, 9, switch.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, form the face of weld 7 and top weld seam 8 thereof after the horizontal jam welding of two block plates.
For detecting the close property of weld seam 8, need to form a seal cavity at weld seam 8, by smearing suds at weld seam 8, the air pressure in the seal cavity is decreased to specified value, when weld seam 8 close property did not reach the regulation parameter, it is not up to standard to show tightness of welding lines that soap bubble will appear in the commissure.
As shown in Figure 1, the device that the utility model provides comprises that namely weld seam covers box 1, vacuum extractor 2, weld seam covers box 1 and is connected by pipeline 3 with vacuum extractor 2, weld seam is covered box 1 cover on the weld seam 8, weld seam covers box 1 and forms seal cavity with the face of weld 7, starts vacuum extractor 2, air pressure in the seal cavity is evacuated to specified value, can begins to detect tightness of welding lines.
By guarantee weld seam cover box 1 and the face of weld 7 the sealing in formations space, as shown in Figure 1, described weld seam covering box is stained with cellular rubber 4 on the surface of contact of itself and the face of weld 7.
Be the negative pressure value in convenient demonstration and the control seal cavity, as shown in Figure 1, cover box at weld seam and be provided with tensimeter 5 that tensimeter 5 connects by the inner chamber that the pressure tapping on the cover plate and weld seam cover box.The pipeline 3 that covers box 1 and vacuum extractor 2 at weld seam is provided with switch 9.
Because when detecting tightness of welding lines, need to observe the suds state at box body inside weld place, so the making of weld seam covering box employing transparent material, during actual production, adopt organic glass to make more.
Because when detecting, the negative pressure value in the seal cavity is crossed when low, and the cell material that weld seam covers box often causes breakage through the pressure of the outside atmosphere of daring not accept, and as shown in Figure 1, covers box inside at weld seam and is provided with support bar 6, and the quantity of support bar can be many.
Weld seam also has other kinds in actual production, accompanying drawing 2 shows a kind of structure of fillet weld, as shown in Figure 2, two block plate vertical weldings form weld seam 8, for detecting the close property of this weld seam, the structure that weld seam shown in Figure 2 covers box 1 is that a cover plate and three face of weld back up pads form, weld seam covers box and face of weld surface of contact opens wide, and weld seam coverage rate and the face of weld form seal cavity.
Can find out that by above-mentioned several welding line structures the structure of weld seam overlay should be comprised of cover plate and two face of weld back up pads that are fixedly connected with the cover plate dorsal edge at least.The claimed technical scheme of the utility model is not limited to the structure that the weld seam described in this embodiment covers box, and the change that covers other structures of welding covering box of carrying out under the enlightenment of box structure at the described weld seam of present embodiment all should belong to protection domain of the present utility model.
