Description

Technical Field

[0001] The present invention relates to the technical field of equipment detection, and in particular to a coating stainless steel pipe leakage testing device. Background Art

[0002] Although stainless steel has a certain degree of corrosion resistance, it may still rust under certain circumstances. Stainless steel can be coated with a coating to increase surface hardness, reduce scratches and wear, and extend its service life. To improve product quality, stainless steel pipes must be leak-tested before leaving the factory. There are several ways to detect leaks in stainless steel, one of which is to test airtightness through a water pressure test. Specifically, the pipe is sealed at both ends and connected to a pressure test pump at one end. The pipe is then placed in water and aerated to observe changes in pressure and the presence of bubbles.

[0003] Currently, there are semi-automatic air tightness testing equipment on the market. Workers need to manually sort qualified products from unqualified products during testing, pick out the unqualified products, and then spray reagents at the leak points. This method is very physically demanding and has low work efficiency. Therefore, the present invention provides a coated stainless steel pipe leakage testing device. Summary of the Invention

[0039] The vertical rod 209 is connected to the first end of a return spring 215, and the second end of the return spring 215 is mounted on the detection bracket 101.

[0040] The working principle of the present invention is as follows: The stainless steel steel pipe to be subjected to airtightness test is put in from one side of the transfer housing 102. The steel pipe rolls into the transfer housing 102 and lands between two partition pieces of two of the conveyor wheels 104. The detection motor 1 301 is started to drive the feeding incomplete gear 112 to rotate. The feeding incomplete gear 112 drives the disc 303 to rotate through the belt 302. When the feeding incomplete gear 112 rotates one week, it drives the disc 303 and the feeding gear 111 to rotate one week. The feeding gear 111 drives the feeding incomplete gear 107 and the feeding reciprocating lead screw 108 to rotate one week, driving the two centering push plates 109 to reciprocate once. When the two centering push plates 109 move relatively, they push the yielding spring 110 and the pushing disc 103 to move. The pushing disc 103 drives the conveyor wheel 104 to move. By the relative movement of the two pushing discs 103, the steel pipe is pushed to the centered position, and steel pipes of different lengths are adaptively adjusted through the yielding spring 110.

[0041] Each time the feeding incomplete gear 107 rotates one week, it drives the feeding gear 106 to rotate a preset angle, driving the spline shaft 105 and the conveyor wheel 104 to rotate a preset angle. Each time the conveyor wheel 104 rotates, one steel pipe at the discharge port of the feeding position in the transfer housing 102 falls between the partition pieces of the conveyor wheel 104, and then the rotating conveyor wheel 104 drives the steel pipes to roll out from the other discharge port of the transfer housing 102 and roll onto the guiding inclined plate 113.

[0042] By starting the detection motor 2 321 to drive the support gear 1 322 to rotate, driving the support gear 2 323 to rotate, driving the rotating shaft 312 to rotate, driving the limiting plate 313 to rotate, so that the opening direction of the limiting plate 313 faces the guiding inclined plate 113. The steel pipe rolls down from the inclined guiding inclined plate 113 and rolls onto the guiding inclined plate 113. Subsequently, the detection motor 2 321 drives the rotating shaft 312 and the limiting plate 313 to rotate again, so that the opening of the limiting plate 313 faces directly upward.

[0043] At this time, the position of the steel pipe corresponds to the detection carriage 1 308, the detection carriage 2 319, and the sealing gasket 320. For steel pipes of different diameters, the height position of the mounting block 318 in the adjusting seat 316 can be adjusted by rotating the adjusting screw 317, so that the axis of the steel pipe corresponds to the axis of the gas transmission pipe 315.

[0044] The hydraulic cylinder 307 is started to extend the piston rod to drive the detection carriage 1 308 to move, driving the rack 1 309 to move, driving the detection gear 310 to rotate, driving the rack 2 311 to move, driving the detection carriage 2 319 to move. The detection carriage 2 319 and the detection carriage 1 308 move relatively to clamp the steel pipe, so that the gas transmission pipe 315 is inserted into the steel pipe, and both ends of the steel pipe are in contact and sealed with a sealing gasket 320 respectively.

[0045] The incomplete feeding gear 112 drives the disc 303 and the eccentric column 304 to rotate through the belt 302, drives the detection connecting rod 305 to swing, drives the lifting frame 306 to descend to the lowest point. There is water in the detection bracket 101, submerging the steel pipe into the water body. Subsequently, the incomplete feeding gear 112 stops rotating, and the air pump 314 pressurizes the steel pipe with air for a preset time to observe whether bubbles are generated.

[0046] After the detection is completed, the incomplete feeding gear 112 continues to rotate, drives the lifting frame 306 to rise through the detection connecting rod 305, and makes the steel pipe leave the water body. The hydraulic cylinder 307 retracts the piston rod, and the detection carriage one 308 and the detection carriage two 319 move away from the detected steel pipe. If no bubbles are generated during the detection process, the detection motor two 321 drives the rotating shaft 312 and the limit plate 313 to rotate towards the separation inclined plate 201. The detected steel pipe on the limit plate 313 rolls towards the separation inclined plate 201 and then rolls into the lower collection box 202.

[0047] Under normal conditions, the monitor 206 monitors the water body situation. If bubbles are found to be generated, the separation motor 204 will start to drive the separation lead screw 205 to rotate one week, driving the monitor 206 to slide a preset stroke on the detection bracket 101. When the monitor 206 slides to the position where bubbles are generated, the marking component 207 sprays the marker to mark the position of the steel pipe bubbles.

[0048] The rotation of the separation lead screw 205 drives the separation turntable 208 to rotate. The rotation of the separation turntable 208 pushes the vertical rod 209 to move downward, compressing the return spring 215. The vertical rod 209 pushes the separation connecting rod 210 to rotate, driving the separation connecting plate 212 to move, driving the separation ejector rod 214 to move upward to push the separation inclined plate 201, so that the separation inclined plate 201 rotates to a position corresponding to the upper collection box 203. Subsequently, when the detection motor two 321 drives the rotating shaft 312 and the limit plate 313 to rotate towards the separation inclined plate 201, the detected steel pipe on the limit plate 313 rolls towards the separation inclined plate 201 and then rolls into the upper collection box 203, separating the qualified products from the unqualified products, facilitating further processing of the leaking steel pipes subsequently.
