Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure detection equipment, in particular to a steel structure anti-corrosion layer detection device. Background Art
[0002] Steel structures occupy a pivotal position in modern construction and industrial fields. Their excellent bearing capacity and stability make them the preferred material for various large-scale facilities. However, steel structures are exposed to the natural environment for a long time and are vulnerable to corrosion factors, resulting in performance degradation and even safety accidents. Therefore, the anti-corrosion work of steel structures is particularly important.
[0003] Anti-corrosion layer testing is an important means to evaluate and monitor the quality of anti-corrosion coatings on the surface of steel structures. Anti-corrosion coatings can effectively isolate steel structures from direct contact with the external corrosive environment and extend the service life of steel structures. However, with the passage of time, anti-corrosion coatings may age, break, and become damaged due to the effects of the external environment, resulting in reduced anti-corrosion effects. Therefore, regular testing of anti-corrosion coatings and timely detection and repair of coating defects are of great significance to ensure the long-term and stable operation of steel structures.
[0004] The traditional method of anti-corrosion layer inspection has long relied on manual operation, using a thickness gauge to measure the thickness of the anti-corrosion layer point by point to evaluate its quality. However, with the rapid development of industrial technology and the continuous expansion of project scale, the limitations of this method have become increasingly obvious. First, manual inspection is inefficient and it is difficult to cope with the large number of inspection needs in large-scale steel structure projects; at the same time, human factors can easily lead to inaccurate inspection results, especially when there are many inspection points, it is difficult to ensure that each point can be inspected in a timely and accurate manner.
[0005] In addition to the low efficiency of traditional anti-corrosion layer detection methods, traditional manual detection methods also face the problem of simultaneous detection of multiple points. During the detection process, manual operation can usually only detect a single point and cannot obtain data from multiple detection points at the same time, which not only reduces the detection efficiency, but also may lead to incomplete and inconsistent data. More importantly, it is difficult to ensure that the detection head of the thickness gauge is always perpendicular to the coating surface due to manual operation, which will have a serious impact on the measurement accuracy. The working principle of the thickness gauge is to calculate the coating thickness based on the vertical distance between the measuring probe and the coating surface. When the probe is not perpendicular to the coating surface, the measurement result will be biased, which will affect the accurate assessment of the quality of the anti-corrosion layer. Utility Model Content
[0006] The utility model aims to provide a steel structure anti-corrosion layer detection device to solve the problems raised in the above background technology.
[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A further improvement of the technical solution of the utility model is that the lifting component includes a second shell, the second shell is fixedly connected to the second limit block, the inner cavity of the second shell is rotatably connected to a bidirectional threaded rod, the inner cavity of the second shell is symmetrically slidably connected to a slider, the two sliders are threadedly connected to the bidirectional threaded rod, and the two sliders are fixedly connected to a clamp.
[0010] The above technical solution is adopted, in which two sliders are threadedly connected to the bidirectional threaded rod, so that the two sliders can be driven to move by rotating the bidirectional threaded rod, and then the clamp can be driven to move by the slider. Since the clamp can fix thickness gauges of different sizes, the thickness gauge can be driven to move when the clamp moves, and then the device can detect the anti-corrosion coating at different heights of the steel structure, thereby improving the detection efficiency of the device, and the thickness gauge is fixed by the clamp, so that when the lifting assembly keeps the tangent perpendicular to the steel structure detection position, the clamp can keep the tangent perpendicular to the steel structure detection position, thereby improving the accuracy of the detection.
[0011] A further improvement of the technical solution of the utility model is that a plurality of slide grooves 1 are symmetrically provided on one side of the semicircular block 1 close to the semicircular block 2, a block assembly is fixedly connected to the side of the semicircular block 1 provided with the slide groove 1, and the inner cavity of the slide groove 1 is communicated with the inner cavity of the adjacent block assembly.
[0012] The above technical solution is adopted, in which a slide groove 1 is provided to facilitate connecting semicircular block 1 with semicircular block 2, and the position of semicircular block 2 can be limited by the clamping block assembly to prevent semicircular block 1 from separating from semicircular block 2 when inspecting the anti-corrosion layer of the steel structure, thereby affecting the inspection.
[0013] A further improvement of the technical solution of the utility model is that a plurality of connecting blocks are symmetrically fixedly connected to one side of the semicircular block 2 close to the semicircular block 1, and a limiting groove used in conjunction with the block assembly is provided on one side of the connecting block close to the block assembly.
[0014] The above-mentioned technical scheme is adopted, in which the connecting block is slidably connected with the slide groove one, and then the cooperation of the card block assembly and the limit groove is facilitated to limit the connecting block in the inner cavity of the slide groove one, so that the semicircular block one and the semicircular block two can fit tightly, and then the semicircular block one and the semicircular block two can be prevented from separating when the anti-corrosion layer of the steel structure is inspected, thereby affecting the inspection.

[0016] The above-mentioned technical solution is adopted, in which the outer shell is threadedly connected to the threaded block, so that by rotating the threaded block, the threaded block can be driven to move in the inner cavity of the outer shell, and then the spring block assembly is pushed to move toward the limit groove, which can facilitate the cooperation between the spring block assembly and the limit groove and limit the position of the connecting block.
[0017] A further improvement of the technical solution of the utility model is that the spring block assembly includes a protrusion, a side of the protrusion close to the threaded block is fixedly connected to a spring, a side of the spring away from the protrusion is fixedly connected to a limiting block 1, and the limiting block 1 is rotatably connected to the threaded block.
[0018] The above-mentioned technical solution is adopted, in which the limit block 1 is rotatably connected with the threaded block, so that when the threaded block is rotated, the limit block 1 can be avoided from being driven to rotate, but when the threaded block moves, the limit block 1 can be driven to move together, and then the limit block 1 can push the spring and the protrusion to move in the direction of the limit groove, and then the protrusion and the limit groove can cooperate to limit the position of the semicircular block 2.
[0019] A further improvement of the technical solution of the utility model is that a stop block is rotatably connected to one side of the bolt, and the stop block is made of rubber material.
[0020] The above-mentioned technical solution is adopted, in which the stop block can be driven to move toward the steel structure by rotating the bolt, and then the stop block is facilitated to contact the steel structure, so that the device can be temporarily connected to the steel structure, thereby facilitating the detection of the steel structure. At the same time, the stop block is made of rubber material, so as to avoid damage to the surface of the steel structure when the stop block contacts the steel structure.
[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0022] 1. The utility model provides a device for detecting anti-corrosion layers of steel structures. Through the sliding connection between the rotating groove and the limit block 2, the parallel component can rotate around the rotating groove, and then the lifting component can be driven to perform rotation detection on the surface of the steel structure, thereby improving the detection efficiency of the device. Through the cooperation of the semicircular block 1, the semicircular block 2 and a plurality of bolts, the device can be temporarily connected to the steel structure, which is conducive to keeping the lifting component parallel to the steel structure at all times, so that the thickness gauge detection head fixedly connected to the lifting component can always be kept vertical to the coating surface, and then it is only necessary to calibrate the verticality of the thickness gauge detection head and the coating surface of the steel structure to be measured once. When the same steel structure is detected multiple times later, there is no need to calibrate the verticality of the thickness gauge detection head and the coating surface of the steel structure, thereby not only improving the accuracy of the detection, but also reducing the time for verticality calibration, thereby improving the detection efficiency.
