Description

Technical Field

[0001] The utility model relates to the technical field of bolt loosening sensor installation, in particular to an installation structure of a high-strength bolt loosening sensor. Background Art

[0002] Bolts are essential and extremely important components in industries such as industrial machinery and equipment, transportation, mining, energy and power equipment. However, the loosening of bolts or nuts caused by vibrations caused by mechanical movement, metal stress, external load and other factors has always been a headache. Once the bolts become loose, they will 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.

[0004] In the prior art, the mounting structure for installing the bolt loosening sensor is mostly connected to the nut by means of bonding, adsorption, clamping or top screwing. When fastened by bonding or adsorption, it is easy to loosen and fall off due to the influence of the external environment. Compared with the fastening methods of bonding and adsorption, the connection stability is relatively high when fastened by clamping or top screwing. However, the fastening method of clamping or top screwing has a mounting structure that is mostly clamped on the outside of the nut, and the limiting effect along the axial direction of the nut is not good. When used in a strong vibration environment, it is still easy to fall off, especially when used on bolts in positions such as swing frames and zip lines. Since park amusement places are densely populated areas, once the equipment loosens and falls off, there is a risk of injuring tourists. For this reason, the utility model proposes an installation method in which the mounting structure and the nut are integrated into a metal base, so as to improve the connection strength of the adaptation structure and the nut, avoid the loosening and falling of the equipment, and eliminate safety hazards.

The installation structure includes a sensor adaptation structure and a metal base. The metal base is fixedly connected to the nut and integrally formed. A plurality of installation holes are provided in the metal base, and screws are movably inserted into the installation holes.
