Description

Technical Field

[0001] The utility model relates to the technical field of bolt loosening sensor installation, in particular to a bolt loosening sensor installation structure with adjustable anchor point height. Background Art

[0002] Bolts are essential and crucial components in industries such as steel bridges, industrial machinery, transportation, mining, energy, and power equipment. However, loosening of bolts or nuts due to mechanical vibration, metal stress, and external loads has always been a significant problem. Once a bolt becomes loose, it can easily break.

[0003] Therefore, bolt loosening sensors have gradually appeared on the market. By installing a bolt loosening sensor on the nut and cooperating with the anchor point installed on the end of the bolt, the two are used together to monitor the looseness of the bolt, including detecting the elongation or rotation angle of the bolt to obtain the looseness of the bolt. The installation distance between the bolt loosening sensor and the anchor point needs to be less than 6mm to ensure the accuracy of the detection data.

[0004] In the prior art, the anchor point is usually fixed on the end of the bolt by threading or bonding, and the height of the anchor point is fixed. During actual installation, it is not convenient to adjust the installation height of the anchor point according to the height of the bolt protruding from the nut, and the usage scenario is relatively limited. In addition, the connection between the existing mounting structure and the nut is mostly fastened by bonding or clamping. Although it can improve the connection stability between the mounting structure and the nut and is suitable for loosening bolts and nuts in strong vibration environments, the installation method is not convenient enough. When used in an environment with low vibration intensity (such as bolts and nuts on steel structure bridges), the vibration intensity is small, and the connection stability requirements between the mounting structure and the nut are low. If the installation method of the mounting structure and the nut is more convenient, the workload during installation can be reduced to improve installation efficiency.

[0005] To address this situation, the utility model adopts a new bolt loosening sensor installation structure. While ensuring that the bolt and nut structure does not change, the installation structure is fastened to the nut by clamping, thereby improving installation convenience. The height of the anchor point is adjusted by adjusting the number of installed anchor points, so that the installation structure can adapt to the height of different bolts protruding from the nut, thereby improving the scope of application.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-5The utility model provides a bolt loosening sensor mounting structure with adjustable anchor point height: used for mounting a bolt loosening sensor 1 on a bolt 2 and a nut 3 (the bolt loosening sensor 1 is a model SA210 wireless bolt loosening sensor produced by Jiaxing Bogan Technology Co., Ltd., and its specific structure and principle are not described in detail here), including a mounting structure for adapting the bolt 2, the nut 3 and the bolt loosening sensor 1, the mounting structure being mounted on the surface of the nut 3 and protruding from the end face of the threaded head of the bolt 2 to support the bolt loosening sensor 1, the mounting structure comprising an adapting fixture 4 clamped and fixed on the outside of the nut 3, the adapting fixture 4 being made of plastic, and the adapting fixture 4 being a hollow structure, a plurality of protruding clamping blocks 5 being fixedly connected to the inner wall of the adapting fixture 4 near the bottom end, a height-adjustable anchor point 6 being provided on the threaded head of the bolt 2, and a magnet being embedded in the anchor point 6 (not shown in the figure);

[0032] By sleeve-mounting the adapter fixture 4 on the outside of the nut 3 and using the raised clamping block 5 on the inner wall of the adapter fixture 4, the adapter fixture 4 is clamped and fixed on the nut 3, thereby fastening the mounting structure to the nut 3. The installation is carried out in a clamping manner, and no auxiliary tools are required during the installation process. The operation is extremely simple and convenient, which can greatly improve the installation effect.

[0033] A threaded hole 7 is provided at the bottom of the anchor point 6, and the anchor point 6 is threadedly mounted on the threaded head of the bolt 2 through the threaded hole 7. A threaded groove 8 is provided on the surface of the anchor point 6 near the top.

[0034] Through the threaded hole 7 opened at the bottom of the anchor point 6 and the threaded groove 8 opened on the outer surface, the anchor point 6 can be installed in a stacked manner by using the threaded hole 7 and the threaded groove 8 in combination, and the height of the anchor point 6 can be adapted according to the height of different bolts 2 protruding from the nut 3, thereby improving the applicability and practicality of the installation structure.

[0035] The thread groove 8 is adapted to fit the thread barrel.

[0036] The adapter fixture 4 and the bolt loosening sensor 1 are fastened by snapping.

[0037] A buckle 9 is fixedly connected to a position near the bottom end of the outer surface of the bolt loosening sensor 1 .

[0038] The top end of the adapter fixture 4 is provided with a slot portion 10 for use with the buckle 9 .

[0039] Working principle: During installation, first install the anchor point 6 on the threaded head of the bolt 2 to be detected through the threaded hole 7. Then, the staff selects the number of superimposed installation anchor points 6 according to the height of different bolts 2 protruding from the nut 3 to adjust the height of the anchor point 6. Then, the adapter fixture 4 is sleeved on the outside of the nut 3. The adapter fixture 4 is clamped and fixed on the nut 3 using the raised clamping block 5 on the inner wall of the adapter fixture 4. The installation method is extremely simple and convenient, and can greatly improve the installation effect. By using the buckle 9 and the slot part 10 in conjunction with each other, the bolt loosening sensor 1 is fastened and installed on the adapter fixture 4 in a buckle manner. This completes the installation of the bolt loosening sensor 1 on the bolt 2 and the nut 3, and monitors the looseness of the bolt 2 and the nut 3.

[0040] If, during actual installation, the height of the bolt 2 protruding from the nut 3 is too short, and only a single anchor point 6 is installed, which cannot meet the requirement of installing the anchor point 6 and the bolt 2 sensor within an appropriate distance range, the staff can use the top of the anchor point 6 installed on the bolt 2 to connect the top of the anchor point 6 to another anchor point 6 through the threaded groove 8 on the anchor point 6 and the threaded hole 7 on the other anchor point 6, so as to achieve the purpose of adjusting the height of the anchor point 6, adapt to the height of different bolts 2 protruding from the nut 3, and improve the applicability and practicality of the installation structure.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
