Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, specifically to a device for testing the wear and corrosion resistance of building steel structures. Background Technology

[0002] In the field of construction engineering, steel structures are widely used due to their high strength and good toughness. However, long-term exposure to complex environments makes them susceptible to corrosion from media (such as acid, alkali, and salt solutions, humid air, etc.), leading to performance degradation and even structural failure. Therefore, testing the wear and corrosion resistance of steel structures is a crucial step in ensuring building safety. Existing testing equipment typically has several shortcomings, such as limited application methods for corrosive media (mostly static spraying or immersion), which fail to simulate the uniform coverage of dynamic corrosive media in real-world environments, resulting in significant deviations in test results. Furthermore, the equipment suffers from low automation, requiring manual intervention during specimen placement and corrosive media application, leading to inefficiency and cumbersome operation. Additionally, the waste collection and treatment functions are inadequate, with corrosive waste easily remaining in the testing chamber, causing equipment corrosion and environmental pollution. Traditional equipment also suffers from poor specimen installation flexibility, making it difficult to adapt to the testing needs of steel structure specimens of different specifications. Therefore, this invention proposes a wear and corrosion resistance testing device for building steel structures to address the shortcomings and deficiencies of existing technologies.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0014] like Figure 1-3As shown, a test equipment for the wear and corrosion resistance of building steel structures includes a test chamber 001, a corrosion application device 002, a rotating mounting structure 003, and a placement rack 004. The rotating mounting structure 003 is installed at the bottom of the test chamber 001, and the corrosion application device 002 is installed on the rotating mounting structure 003. The placement rack 004 is installed at the top of the test chamber 001. The test specimen is fixed to the grid structure of the placement rack by a clamp, which facilitates the uniform spraying of the corrosive liquid onto the surface of the test specimen. The test chamber 001 has a sealing door 110 on the side, which is sealed with double-layer rubber strips to ensure that the corrosive medium does not overflow during the test. The corrosion application device 002 includes a mounting base 210, a corrosion-resistant vertical beam 220, a fixing sleeve 230, a solenoid valve 240, an atomizing nozzle 250, a corrosion-resistant hose 260, a corrosion-resistant tube 1 270, a corrosion-resistant tube 280, a rotating abutment tube 290, a liquid pump 2010, and a corrosion-resistant storage tank 2011.

The atomizing nozzle 250 is mounted on the corrosion-resistant vertical beam 220 via the fixing sleeve 230. The corrosion-resistant hose 260 is connected to the atomizing nozzle 250 via the solenoid valve 240. The spray nozzle 250 uses a high-pressure pneumatic nozzle to atomize the corrosive liquid into droplets with a particle size of 50-100μm. As the rotating seat 310 rotates, the droplets are evenly sprayed onto the surface of the specimen. The corrosion-resistant tube 1 270 and the corrosion-resistant tube 280 are connected by a rotating abutment tube 290. The corrosion-resistant tube 1 270 passes through the mounting groove 211 between the mounting and fixing seats 210. The corrosion-resistant tube 1 270 passes through the central mounting groove 311 of the rotating seat and forms a rotary seal connection with the rotating abutment tube 290, allowing the pipe to maintain liquid communication when it rotates with the rotating seat. The corrosion-resistant tube 280 is connected to the bottom of the corrosion-resistant liquid storage tank 2011, and the liquid pump 2010 is connected between the corrosion-resistant tubes 280.

The rotary seat 310 is mounted on the bottom of the test box 001 via the bearing 330. A corrosion-resistant tube 270 passes through the mounting groove 311 between the rotary seats 310. The rotary gear 320, which meshes with the drive gear 340, is fixedly mounted on the bottom of the rotary seat 310. The drive motor 350 is mounted on the bottom of the test box 001, and the output end of the drive motor 350 is connected to the drive gear 340.

[0016] Further optimizations to this solution include: Figure 1-3 As shown, a sealing ring 331 is provided on the outside of the bearing 330. The outer sealing ring 331 of the bearing is made of fluororubber to prevent liquid inside the housing from seeping into the bearing and causing corrosion.

[0018] Further optimizations to this solution include: Figure 1-3 As shown, the bottom of the detection box 001 is tilted at 130 degrees with an inclination angle of 5°. The bottom of the detection box 001 is equipped with a waste liquid collection tank 006 that connects to the inside of the detection box 001.
