Description

Technical Field

[0001] This utility model relates to the field of steel structure corrosion detection technology, and specifically to a steel structure corrosion detection device. Background Technology

[0002] Steel structure corrosion testing equipment is an important tool for detecting and evaluating the quality and performance of anti-corrosion coatings on steel structure surfaces.

[0003] Coating thickness testing devices utilize principles such as ultrasound, magnetism, or eddy current to measure the thickness of anti-corrosion coatings on steel structure surfaces. When using these devices to test the thickness of anti-corrosion coatings on steel structure surfaces, workers typically need to perform multi-point testing while ensuring that the spacing between adjacent testing points is roughly the same. In practice, workers usually judge the spacing between testing points based on experience, which can easily lead to uneven spacing, thus affecting the accuracy and reliability of the overall testing results. Too large a spacing may miss some potential problem areas, while too small a spacing may increase unnecessary testing workload. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a steel structure corrosion detection device.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A steel structure corrosion detection device, comprising:

[0007] Thickness measuring instrument;

[0008] Flexible connecting rod;

[0009] A fixing rod is fixed to the thickness measuring instrument;

[0010] A first clamping structure is disposed at one end of the flexible connecting rod;

[0011] The second clamping structure is located at the other end of the flexible connecting rod.

[0012] As a further embodiment of this utility model: the first clamping structure includes:

[0013] Shaft;

[0014] The first sleeve is rotatably sleeved on the shaft, and the first sleeve is fixedly connected to the end of the fixed rod away from the thickness measuring instrument.

[0015] The first pressure block is fixed to one end of the shaft.

[0016] As a further embodiment of this utility model: the second clamping structure includes:

[0017] A sliding sleeve is slidably fitted onto the flexible connecting rod;

[0018] The second pressure block is rotatably mounted on one end of the sliding sleeve;

[0019] A threaded opening is formed on the sliding sleeve;

[0020] The fastening bolt is threaded into the threaded opening.

[0021] As a further embodiment of this utility model: a knob is fixed to the end of the fastening bolt away from the flexible connecting rod.

[0022] As a further embodiment of this invention, the flexible connecting rod is made of rubber material.

[0023] As a further aspect of this utility model, both the first pressing block and the second pressing block have anti-slip textures on their surfaces.

[0024] The beneficial effects of this utility model are:

[0025] 1. By rotating the flexible connecting rod, the operator can easily control the distance between two adjacent detection points. Since the flexible connecting rod has a certain length and can rotate between two pressure blocks (the first pressure block and the second pressure block), after each 180° rotation, the distance between the detection points is equal to twice the distance between the first pressure block and the second pressure block. This design allows the operator to control the spacing between detection points without relying on experience or estimation, thereby improving the accuracy and reliability of the detection.

[0026] 2. The free sliding design of the sliding sleeve on the flexible connecting rod provides the operator with another way to adjust the spacing between the detection points. By turning the knob on the fastening bolt, the operator can easily release the restriction on the sliding sleeve, then slide the sliding sleeve on the flexible connecting rod to the desired position, and finally, tighten the fastening bolt again to fix the position of the sliding sleeve, thereby changing the spacing between two adjacent measurement points. This design makes the detection device more flexible. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figure 1-4 As shown, a steel structure corrosion detection device includes: a thickness gauge 1 (the specific structure and working principle of the thickness gauge 1 are not considered innovative aspects of this technical solution and are not shown in the figure, nor will they be described in detail here); a flexible connecting rod 2 made of rubber material, the variability of which facilitates the separation of the thickness gauge 1 from the steel structure surface, preventing friction between the thickness gauge 1 and the steel structure surface during rotation); and a fixing rod 3 fixed to the thickness gauge 1.

[0035] The steel structure corrosion detection device also includes a first clamping structure, which is set at one end of the flexible connecting rod 2. The first clamping structure includes: a shaft 41; a first sleeve 42, which is rotatably sleeved on the shaft 41 and is fixedly connected to the end of the fixed rod 3 away from the thickness measuring instrument 1; and a first pressure block 43, which is fixed at one end of the shaft 41.

[0036] The steel structure corrosion detection device also includes a second clamping structure, which is set at the other end of the flexible connecting rod 2. The second clamping structure includes: a sliding sleeve 51, which is slidably sleeved on the flexible connecting rod 2; a second pressure block 52, which is rotatably installed at one end of the sliding sleeve 51, and the surfaces of the first pressure block 43 and the second pressure block 52 are provided with anti-slip textures; a threaded opening 53, which is opened on the sliding sleeve 51; and a fastening bolt 54, which is threaded into the threaded opening 53. A knob is fixed at the end of the fastening bolt 54 away from the flexible connecting rod 2. The operator can control the distance between two adjacent detection points by rotating the flexible connecting rod 2. In addition, the operator can control the distance between two adjacent detection points by adjusting the position of the sliding sleeve 51. When the position of the sliding sleeve 51 changes, the distance between two adjacent measurement points will also change.

[0037] The working principle of this utility model:

[0038] When using the steel structure corrosion detection device proposed in this utility model, in the initial state, the sliding sleeve 51 is located at the end of the flexible connecting rod 2 away from the fixed rod 3. The operator first places the thickness gauge 1 against the surface of the steel structure and presses the second pressure block 52 against the surface of the steel structure. The thickness gauge 1 is used to perform the first detection on the steel structure. After the first detection is completed, the operator presses down the second pressure block 52 and then rotates the flexible connecting rod 2 so that the flexible connecting rod 2 rotates around the second pressure block 52. When the flexible connecting rod 2 rotates 180°, the thickness gauge 1 is located below the second pressure block 52. At this time, the operator uses the thickness gauge 1 to perform the second detection on the surface of the steel structure. At this time, the distance between the first detection point and the second detection point is twice the distance between the first pressure block and the second pressure block.

[0039] After the second inspection, the staff pressed down on the first pressure block 43, causing the flexible connecting rod 2 to rotate around the first pressure block 43 until the second pressure block 52 rotated to the bottom of the first pressure block 43. Then the staff pressed down on the second pressure block 52 again, causing the flexible connecting rod 2 to rotate around the second pressure block 52 until the first pressure block 43 rotated to the bottom of the second pressure block 52 again. At this time, the staff used the thickness measuring instrument 1 to conduct a third inspection on the surface of the steel structure, and the distance between the third inspection point and the second inspection point was twice the distance between the first and second pressure blocks.

[0040] Based on the above process, staff can control the distance between two adjacent detection points by rotating the flexible connecting rod 2, which makes it easier for staff to control the distance between two adjacent detection points;

[0041] The sliding sleeve 51 can slide freely on the flexible connecting rod 2. The operator can control the distance between two adjacent detection points by adjusting the position of the sliding sleeve 51. Specifically, the operator turns the knob on the fastening bolt 54 to separate the fastening bolt 54 from the flexible connecting rod 2, thereby releasing the restriction of the fastening bolt 54. The sliding sleeve 51 can then slide on the flexible connecting rod 2. After adjusting the sliding sleeve 51 to a suitable position, the operator turns the knob in the opposite direction to make the fastening bolt 54 press against the flexible connecting rod 2 again, thus fixing the sliding sleeve 51 with the fastening bolt 54. When the position of the sliding sleeve 51 changes, the distance between two adjacent measurement points will also change.

[0042] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
