Description

Technical Field

[0001] This application relates to the field of bellows technology, specifically to a high-speed testing device for bellows life. Background Technology

[0002] A corrugated pipe is a flexible pipe with a corrugated structure that can withstand axial, radial and angular displacements while maintaining sealing and pressure resistance. With the increasing popularity of corrugated pipes, it is necessary to conduct tests on them to ensure their performance. Therefore, a high-speed test device for corrugated pipe life is needed.

[0003] Chinese patent CN221037994U discloses a swing fatigue testing device for a double-section metal bellows, including a chute fixing platform, a specimen limiting mechanism, a power swing mechanism, and a flange swing rod of the swing end flange on the bellows specimen that is rigidly connected to the swing rod through a support rod. The power swing mechanism drives the swing end flange to swing back and forth, thereby realizing the swing fatigue life test of the bellows specimen.

[0004] However, the aforementioned device tests the lifespan of the corrugated pipe through a power swing mechanism during use, but it is inconvenient to check for cracks or leaks in the corrugated pipe during the test. Therefore, a second test is still required after the first test, which is time-consuming and labor-intensive. In view of this, we propose a high-speed corrugated pipe lifespan testing device.

[0030] Reference Figure 1 , Figure 2 and Figure 3 This application provides a high-speed test device for the life of a bellows, including a support body 1, a test mechanism 2, a transmission mechanism 3, and a bellows 4. The test mechanism 2 is located inside the support body 1, and the bellows 4 is located in the middle of the test mechanism 2. The test mechanism 2 includes a pressure plate 209 for pressure testing the bellows 4 and a water injection nozzle 204. The pressure plate 209 is located below the water injection nozzle 204, and the water injection nozzle 204 is used to inject water into the bellows 4 tested by the pressure plate 209.

[0031] The pressure plate 209 is used to test the pressure of the bellows 4, so as to understand the strength of the bellows 4. Then, water is injected into the bellows 4 through the water injection nozzle 204, so as to understand whether the bellows 4 has cracks or leaks after the pressure test. This is convenient and quick to detect, saving time and effort.

A first sealing groove 207 is fixedly installed on the lower surface of the pressing plate 206. The first sealing groove 207 is in close contact with the bellows 4. The water injection nozzle 204 is located on the lower surface of the pressing plate 206.

[0033] A water tank 201 is fixedly installed on the top of the support body 1. A pump body 202 is fixedly installed on one side of the water tank 201. The input end of the pump body 202 extends into the interior of the water tank 201, and the output end of the pump body 202 extends into the interior of the support body 1. An elastic hose 203 is fixedly installed at the output end of the pump body 202. The elastic hose 203 extends to the lower surface of the pressing plate 206 and connects with the water injection nozzle 204.

[0034] Hydraulic rods 208 are fixedly installed on both sides inside the support body 1, and the output end of the hydraulic rods 208 is connected to the pressure plate 209.

[0035] By activating the electric telescopic rod 205, the electric telescopic rod 205 drives the pressing plate 206 to adjust, thereby facilitating the contact between the first sealing groove 207 at the bottom of the pressing plate 206 and the bellows 4. Then, the hydraulic rod 208 is activated, and the hydraulic rod 208 drives the pressure plate 209 to perform a pressure test on the bellows 4. After the pressure test is completed, the pump body 202 is activated, and the pump body 202 draws water from the water tank 201 through the input end. Then, the water is delivered to the elastic hose 203 through the output end of the pump body 202. Finally, the water is injected into the bellows 4 through the water injection nozzle 204, thereby facilitating the detection of whether the bellows 4 is leaking.

[0036] Reference Figure 3 and Figure 4 In one aspect of this embodiment, the transmission mechanism 3 includes a slide groove 301 formed at the bottom of the support body 1. A threaded rod 302 is movably connected inside the slide groove 301. A motor 303 is fixedly installed on the rear side of the support body 1. The output end of the motor 303 extends into the slide groove 301 and connects with the threaded rod 302. A slider 304 is slidably connected inside the slide groove 301. The slider 304 is threadedly connected to the threaded rod 302. A test frame 305 is fixedly installed on the upper surface of the slider 304. Two auxiliary rods 307 are fixedly installed on the upper surface of the test frame 305. A bellows 4 is sleeved on the auxiliary rods 307. A second sealing groove 306 is fixedly installed on the upper surface of the test frame 305. The second sealing groove 306 is in close contact with the bellows 4.

[0038] The corrugated pipe 4 is easily fixed by the auxiliary rod 307 on the test frame 305. After fixing, the second sealing groove 306 is in close contact with the corrugated pipe 4, which facilitates subsequent operations. Then, by starting the motor 303, the motor 303 drives the threaded rod 302 to rotate inside the slide groove 301. The threaded rod 302 moves in conjunction with the slider 304, thereby moving the test frame 305 to the designated position for testing. After the test is completed, by pulling the adjusting plate 310, the adjusting plate 310 slides inside the water discharge adjusting groove 309, which facilitates the release of water from the corrugated pipe 4. Finally, the water is discharged through the leakage groove 308 at the bottom of the support body 1.

[0039] All electrical devices in this plan are powered by an external power source.

[0040] Working principle: In use, the corrugated pipe 4 is first secured by the auxiliary rod 307 on the test frame 305. After securing, the second sealing groove 306 is in close contact with the corrugated pipe 4. Then, the motor 303 drives the threaded rod 302 to rotate inside the slide groove 301. The threaded rod 302 moves in conjunction with the slider 304, which in turn moves the test frame 305 to the designated position. Subsequently, the electric telescopic rod 205 adjusts the pressing plate 206, facilitating contact between the first sealing groove 207 at the bottom of the pressing plate 206 and the corrugated pipe 4. Then, the hydraulic rod 208 is activated, which drives the pressure plate 209 to perform a pressure test on the bellows 4. After the pressure test is completed, the pump body 202 is activated, and the pump body 202 draws water from the water tank 201 through the input end. Then, the water is delivered to the elastic hose 203 through the output end of the pump body 202. Finally, the water is injected into the bellows 4 through the water injection nozzle 204, which facilitates the detection of whether the bellows 4 is leaking. After the test is completed, the adjusting plate 310 is pulled and slid inside the water discharge adjusting groove 309, which facilitates the release of water from the bellows 4.
