Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done explanation in further detail.
As shown in Figure 1, the quality detection device of ship plate butt-weld comprises detection case 1, detection case hold-down mechanism 2, alcohol container 3 (alcohol gas of alcohol container stored certain pressure), alcohol detector 4 and alarm 5.The structure of detection case 1 is as shown in Figure 2; The open top of detection case 1 is provided with packer ring 6 at the top of detection case 1, and detection case 1 is provided with air intake opening 7 and gas outlet 8; Air intake opening 7 is connected with alcohol container 3 through tracheae, and gas outlet 8 is connected with alcohol container 3 through vacuum pump 9.Detection case hold-down mechanism 2 comprises the clamp 12 on the ship plate to be detected 13 that may be stuck in that the two ends of supporting baseplate 10, lifting jack 11 and supporting baseplate 10 are provided with respectively, and supporting baseplate 10 is as shown in Figure 3 with the structure of clamp 12 assemblings.Detection case 1 is arranged on the bottom of ship plate butt-weld; Supporting baseplate 10 is positioned at the below of detection case 1; The clamp 12 of supporting baseplate 10 both sides is stuck on the ship plate 13, and lifting jack 11 is between supporting baseplate 10 and detection case 1, and the bottom of lifting jack 11 is pressed on the supporting baseplate 10; The top of lifting jack 11 is pressed on the detection case 1, and the packer ring 6 at detection case 1 top is pressed on the bottom surface of ship plate 13 of butt-weld both sides.
Alcohol detector 4 is over against at the top of ship plate butt-weld, and connects alarm 5 through signal wire.Detected alcohol at alcohol detector 4 and existed, just with the signal input alarm 5 that detects, alarm 5 is reported to the police.
This quality detection device also comprises slide rail 15, and alcohol detector 4 is installed on the slide rail 15 and with slide rail 15 and is slidingly matched.The structure of slide rail 15 is as shown in Figure 4, and the longitudinal direction of slide rail 15 is provided with two chutes 17, and the bottom of alcohol detector 4 is provided with pulley, and pulley is placed in the chute 17 and can in chute 17, slides.
In the present embodiment, the top of clamp 12 bends inwards, and is colluding the both sides of ship plate 13 through the part that bends inwards, thereby clamp 12 is stuck on the ship plate 13.Be fixed with support plate 16 in the both sides of detection case 1; The top of lifting jack 11 withstands on the support plate 16; The base of lifting jack 11 is placed on the supporting baseplate 10; Jacking sleeve through lifting jack 11 passes to support plate 16 with power, and then passes to the packer ring 6 on the detection case 1, makes the bottom surface sealing of packer ring 6 with the ship plate 13 at detection case 1 top.
The step of using the quality detection device of this ship plate butt-weld to detect is following:
1), the ship plate 13 after will docking keeps flat; Detection case 1 and detection case hold-down mechanism 2 are placed on the bottom of butt-weld; Supporting baseplate 10 is positioned at the below of detection case 1, and the clamp 12 at the two ends of supporting baseplate 10 is stuck on the ship plate 13, makes supporting baseplate 10 be hung in the below of ship plate 13.Lifting jack 11 is installed between supporting baseplate 10 and the detection case 1; The bottom of lifting jack 11 is pressed on the supporting baseplate 10; The top of lifting jack 11 is pressed on the detection case 1; The packer ring 6 at detection case 1 top is pressed on the bottom surface of ship plate 13 of butt-weld both sides, through regulating the adjustable height of lifting jack 11, and then the snap-in force of regulating packer ring 6 and the bottom surface of ship plate 13.
2), the valve of giving vent to anger on the unlatching alcohol container 3; In detection case 1, inject alcohol gas through tracheae; The pressure that the tensimeter 14 that passes through to be provided with on the detection case 1 again shows in the detection cases 1, the pressure in the detection case 1 kept this pressure at least 30 minutes when being higher than the pressure outside the detection case 1 and reaching setting value.Setting value is mainly the pressure that the watertightness cabin is born; When actual detected, this setting value is often than the big 0.1～1MPa of pressure that watertightness cabin bore.
3), alcohol detector 4 is moved along the top of butt-weld, if in moving process, alcohol detector 4 detects the alcohol smell, and alarm 5 sends warning, and then explanation is should place's welding quality defective; If in the moving process, alcohol detector 4 does not detect the alcohol smell, alarm 5 does not send warning, and the up-to-standard of this butt-weld then is described.Alcohol detector 4 is in moving process, in case alarm 5 sends warning, just makes mark in this butt-weld leakages, so that follow-uply carry out repair welding.After detection finishes, open air intake valve and vacuum pump 9 on the alcohol container 3, vacuum pump 9 is with in the alcohol gas suction alcohol container 3 in the detection case 1, so that this alcohol gas is able to recycling.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
