Description

Technical Field

[0001] This utility model belongs to the field of rust prevention and detection technology for steel structure buildings, and specifically relates to a rust prevention inspection device for the inspection and identification of steel structure buildings. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be derusted, galvanized or painted, and regular maintenance is required. In order to prevent the impact of steel structure rust on the stability of the building, it is necessary to conduct rust prevention testing and evaluation on the treated steel structure.

[0003] However, steel structure buildings are prone to rusting during use, affecting their quality and consequently impacting rust prevention test results. Existing technology, as disclosed in patent publication number CN214067132U, involves a steel structure rust prevention testing device for testing and evaluation. This device includes a base with a first groove in the center of its upper surface. A turntable is housed inside the first groove, and a transparent cylinder is also housed inside the first groove. A first limiting groove, adapted to the turntable, is located on the bottom surface of the transparent cylinder. The top of the turntable is situated within the first limiting groove. A support rod is located in the center of the upper surface of the turntable. A water tank and an oxygen cylinder add atomized water and oxygen to the transparent cylinder, creating a humid and oxygen-rich environment. This allows operators to control the amount of water and oxygen to test the rust prevention ability of samples, improving the accuracy of the test.

[0004] However, the above-mentioned rust detection device has the following problems when in use:

[0005] 1. During the rust prevention testing of steel structures, it is difficult to spray water mist evenly onto the steel structure being tested, making it difficult for the steel structure to fully contact the water mist and oxygen.

[0006] 2. Factors that cause steel corrosion include oxygen, water, salt, temperature, and acidic substances. However, the aforementioned rust prevention inspection device only provides two factors: water and oxygen. This can easily lead to inaccurate inspection results and slow inspection efficiency.

A drive gear is provided at the end of the motor drive shaft. A driven gear that meshes with the drive gear is provided at the lower end of the rotating shaft. The upper end of the rotating shaft passes through the upper bushing at the bottom of the detection box and is connected to the placement platform.

[0012] By adopting the above technical solution, the lifting plate is driven by a hydraulic rod to move up and down along the support guide rod, which in turn moves the placement platform up and down inside the testing box. The motor is controlled to drive the placement platform to rotate inside the testing box via the rotating shaft, so that the water mist spraying on the steel structure to be tested on the placement platform is more uniform.

[0013] Furthermore, the top of the detection box described in this utility model is rotatably connected to a detection box cover, an observation window is provided on the front end face of the detection box, and a temperature and humidity detector for detecting the internal temperature and humidity is also provided on the detection box.

[0018] 1. By utilizing the oxygen generator, circulating fan, heating box, water pump, and acid gas box connected to the inside of the equipment box and the testing box, oxygen, salt spray, hot air heating, and acid gas are respectively introduced into the testing box, making the inspection environment inside the testing box more diverse and the inspection results more accurate.

[0019] 2.

Pump 34 and acid gas tank 37; the upper ends of the inner walls on both sides of the detection box 4 are provided with oxygen nozzles 46 and water mist nozzles 45, which are respectively connected to oxygen generator 31 and water pump 34; the water inlet of water pump 34 is connected to water tank 35 through pipeline; the lower ends of the inner walls on both sides of the detection box 4 are provided with air outlet plates 47, which are respectively connected to circulating fan 32 and acid gas tank 37; the air inlet of circulating fan 32 is connected to the inside of installation box 2 through heating box 33 and air pipe; a solenoid valve 36 for controlling the gas supply of air outlet plate 47 is provided above acid gas tank 37.

[0036] The drive mechanism 7 includes a hydraulic rod 71, a lifting plate 72, and a motor 73. The two ends of the lifting plate 72 are slidably mounted on the support guide rod 23 via guide sliders. The bottom of the lifting plate 72 is connected to the top of the hydraulic rod 71 installed at the bottom of the mounting box 2. The top of the lifting plate 72 is connected to the bottom of the rotating shaft 6 via a bearing seat. The motor 73 is mounted on the lifting plate 72. The motor 73 has a drive gear 74 at the drive shaft end. The lower end of the rotating shaft 6 has a driven gear 61 that meshes with the drive gear 74. The upper end of the rotating shaft 6 passes through the upper bushing 44 at the bottom of the detection box 4 and is connected to the placement platform 5.

[0037] The top of the test box 4 is rotatably connected to the test box cover 41. The front end face of the test box 4 is provided with an observation window 43. The test box 4 is also provided with a temperature and humidity detector 42 for detecting the internal temperature and humidity.
